TG series Series overview TGL
The TGL was presented in 2005. With gross weight ratings from 7.5 to 12 t, the MAN TGL covers the whole range of transport tasks in its application field. The 7.5 t version is a super-light specialist vehicle with high payload intended primarily for use by rental companies, fleets and small companies. The four-cylinder engine with a maximum output of 240 hp and the light C cab are designed to meet the corresponding requirements. 4 fixed wheelbase/overhang combinations are available in this weight class. The complete wheelbase range and the flexible frame rear end are available from a GWR of 8.0 t to permit realisation of all vehicle variants. A crew cab complements the range of cabs for local and long-distance operation. The engine type D08 is used in the TGL.
1.4
LF-02a[1]. TG-allg.-01-Einführung-0805 FH-en.doc
TGM
The TGM is in a class of its own with engines of the type D08, offering outputs from 240 hp to 326 hp and weight ratings of between 13 and 26 t. Combined with matching chassis variants, this model range has offered economical and reliable transport solutions since 2005. The crew cab rounds off the range of cabs for local and long-distance operation. The vehicle components are based on the Trucknology® modular system.

TGA / TGS / TGX
The TGA covers the weight class from 18 tonnes. The MAN TGS / TGX was presented in autumn 2007 and was chosen as "Truck of the Year 2008" at the European Road Transport Show 2007 in Amsterdam.

Difference compared with previous vehicle identification number (up to 1999): The 7-digit vehicle number (formerly "planning number") is no longer part of the vehicle identification number. Instead, the vehicle identification number has two "Z" characters as filler characters, a check character and a letter or digit specifying the model year at the corresponding positions.

Characters 12 to 17 Sequential number, line-dependent: The sequential number is assigned independently of vehicle type to all vehicles built on a line. The number is assigned in the order in which the vehicles leave the line. It must therefore always be considered in conjunction with the plant code.

LF-02a[1]. TG-allg.-01-Einführung-0805 FH-en.doc
Vehicle number
The vehicle number (formerly "planning number") consists of the type code number and a 4-digit sequential number. The sequential number can also contain letters. It is assigned type-independently when construction of a vehicle is defined, irrespective of the assembly line on which it is then built. This "planning number" was previously part of the vehicle identification number. Since 1st July 1999, the vehicle number can no longer be determined from the vehicle identification number. It is now located on a yellow sticker on the vehicle frame, for example, and on the identification plate (type plate). The vehicle number can be found on the identification plate (e.g. type plate on the door pillar on the passenger's side).

Service Information Bulletins can be called up via the Intranet / Extranet. VNSTT produced the Service Bulletin SM 700 b on this. In June 1998, the Service Information numbering system was changed from a date-like numbering system with a suffixed group number (e.g. 170698/10) to sequence numbers with suffixed group number. (e.g. 23210) LF-02a[1]. TG-allg.-02-Dokumentation-0805 FH-en.doc

The comfort cab suspension is standard for the long-distance cabs L32/ 37/ 40/ 41. The air-sprung 4-point cab suspension allows a maximum spring travel of +/-45mm. The air suspension is controlled by means of 3 level-control valves located at the front right and left and rear right.
Level-control valve mechanical external
Current cab air suspension system A 4-point suspension is also installed, but the spring bags are no longer controlled by means of level-control valves. Instead, the control is integrated in 3 spring bags and is realised by means of a lever on a cam track.
New cab air suspension system Sliding guide for valve control The air spring bag can become trapped between the level control mechanism and rolling piston if it is loaded when not pressurised! For this reason, connect the air supply before loading the air spring.

LDS Air Spring Damping System
The air spring and shock absorber are combined in one unit (air spring damping system, LDS). The air suspension allows the fully loaded forward-control vehicle to be lowered by 90 mm from ride level and to be raised by 90 mm (the total travel is 280 mm). On a fully loaded low truck - car transporter, the system permits lowering by 60 mm from ride level and lifting by 160 mm (the total travel is 220 mm).

Rear axle X-arm The X-arm performs all axle guidance tasks (transverse and longitudinal) and also the function of the stabilisers. This means that it is possible to omit trailing arms and A-arms as well as the stabilisers, thereby achieving a weight saving of approx. 45 kg. The X-arm provides extremely precise axle guidance and therefore improves tracking, driving stability and roll stabilisation. The favourable restoring force characteristic improves driving stability in the event of rolling movements.

ECAS air suspension system The designation ECAS stands for: Electronically Controlled Air Suspension
ECAS is an electronically controlled air suspension system for motor vehicles. ECAS functions ECAS includes the following functions: ⇒ Increased driving comfort and protection of the transported goods through a lower spring rate and low natural frequency. ⇒ Constant vehicle height independent of load. ⇒ Possibility of level adjustment on one side. The following improvements were realised, among others: ⇒ Reduced air consumption while driving. ⇒ Lower installation volume of complex systems. ⇒ Additional functions such as kneeling, overload protection for low-speed traction control. ⇒ Accelerated air filling and venting operations thanks to large valve cross-sections. The control electronics is the heart of the system. Task of the control unit ♦ Permanent monitoring of incoming signals ♦ Comparison of these values (actual values) with stored values (setpoints) ♦ Calculation of required control reaction for every deviation ♦ Activation of the solenoid valves Additional tasks of the control unit ♦ Management and storage of the different setpoints. ♦ Data exchange via the T-CAN and MAN-Cats II ♦ Regular monitoring of the functioning of all system parts ♦ Plausibility check of received signals to detect faults

MAN HydroDrive®
Special feature of this system: If required, the front wheels are additionally driven at the push of a button. Unlike in the past, when this was achieved by means of a transfer case and propshafts, this is realised here with two hydraulic wheel hub motors. In contrast to vehicles with conventional all-wheel drive, trucks equipped with the MAN HydroDrive® system are also ideally suited for primary use in on-road operation. In normal driving mode, trucks equipped with MAN HydroDrive® drive as usual with rear-wheel drive. However, the transport task may also require the vehicle to be driven off unpaved roads - possibly on difficult terrain or on a construction site - or it may have to cope with difficult driving conditions such as snow or ice. In such situations, the MAN HydroDrive® can be activated in the cab, and the hydrostatic wheel hub motors integrated in the front wheels additionally drive the front axle. Activation of the MAN HydroDrive® even functions under load and up to a speed of 28 km/h. The significantly higher traction provided by four wheels allows stuck vehicles to be moved off again.

Steering knuckle The kingpins have three steps and are inserted from "above" with the axle in installation position. The grease DEA Acron OS3 ( 09.15006.0015 ) is used for initial grease lubrication on assembly. Any grease nipples still present are needed only for production (initial assembly grease filling) and are covered by cap closures. The disc brakes, wheel bearings and axle knuckles are identical for steered front, leading and trailing axles.
HUB UNIT The wheel bearing was also changed with the introduction of "LUCAS D-ELSA" disc brakes. These axles are equipped with "HUB UNIT" wheel bearings. The bearing assembly is provided with for-life lubrication and is encapsulated. There is no need for a prescribed annual grease change. When the disc brakes are replaced, the wheel bearing remains on the axle knuckle as a completely closed unit.

The leading or trailing axle is steered hydraulically by means of a hydraulic cylinder. Angle sensors are fitted on the steering gear and on the leading or trailing axle. These sensors measure the steering angle and transmit the values to the control unit and valve block. The hydraulic pressure is 160 - 170 bar. This is generated by a maintenance-free vane pump, which is driven by the air compressor via a cross coupling.

Adjustment with skew steering wheel
If the steering wheel is skew, the steering is not adjusted by moving the steering wheel on the steering spindle. The steering must be in neutral position on the steering gear as shown in Figure 1. Fine adjustment is then performed by means of the thread on the pushrod to the steering arm on the axle knuckle.

The Electronic Brake System consists of three sub-functions. The system components are as follows: EBS control unit, service brake module, pressure regulating modules, trailer control module, rotational speed sensor, brake pad wear sensor, axle load sensor. The EBS control unit controls the pressure in the brake cylinders of the brake system with the pressure regulating modules. A connected trailer with ABS is controlled via the brake line with the trailer control module. Trailers with EBS are controlled by the EBS CAN bus via the ABS socket. The deceleration rates of the tractor and trailer are matched to each other by the integrated coupling force control system.
3.38
LF-02a[1]. TG-allg.-03-Rahmen-Fahrwek-0805 FH-en.doc
If the EBS is de-energised, has failed or if there are faults in the system, the system becomes a pure air brake system with two service brake circuits. When the vehicle is braked, the service brake valve builds up pressure in the brake cylinders on the front and rear axles. However, the pressure in the brake cylinders is not regulated and depends only on the brake pedal position.
Special features ¾
EBS Knorr 5 and Wabco 2 do not have an axle load sensor.
¾
The axle loads are detected by way of the slip behaviour.
¾
The trailer control modules do not have any control units.
¾
In the case of Wabco 2, the EBS control unit, service brake module and front axle module are installed as one unit in the central brake module.

Functional description Brake clamping When braking takes place, the force of the brake cylinder (combination or diaphragm brake cylinder) acts on a lever arm. This lever arm transmits the force to the bridge via the roller bearing.
The clamping force acts on the inner brake pad via the threaded tubes and thrust pieces. After the clearance between the brake pad and brake disc has been overcome, the reaction force is transmitted to the outer brake pad via the brake calliper (sliding calliper). The braking torque for the wheel is produced by the brake pad pressure on the brake disc. Brake release When the forces of the brake cylinder are reduced, the compression spring presses the bridge with threaded tubes and the lever arm back to the initial position.
LF-02a[1]. TG-allg.-03-Rahmen-Fahrwek-0805 FH-en.doc
3.43
Brake adjustment The brake is equipped with an automatic, wear-free adjusting device that ensures a constant clearance between the brake pads and the brake disc. Each brake operation also results in operation of the adjuster, which has a positive connection with the lever arm.

In the event of increased clearances due to brake pad and brake disc wear, the threaded tubes are preturned by the adjuster by the wear dimension. The total clearance is 0.6 - 1.1 mm. (total clearance on both sides of the brake disc) A smaller clearance can lead to overheating problems and increased wear!

As with conventional fuel injection systems, the EDC system also consists of an injection pump and a governor. A control sleeve pump is installed in the EDC MS 6.1 (M = fuel delivery control; S = timing adjustment). Both systems are controlled by a microprocessor-based control unit. The program memory of this control unit contains all the maps defined for the engine.
The great advantage of the EDC system is the actuator mechanism, which is always the same irrespective of the map. In other words, the control unit is exclusively responsible for the maps, corrections, etc. On mechanical governors, in contrast, all the components that affect the control characteristic (flyweight parts, spring sets, and compensating devices such as torque control spring capsules, stops, etc) are actually integrated in the governor. If it is wished to change the control characteristic, it is therefore necessary to replace these parts. In the EDC system, there is no mechanical connection between the accelerator and governor. The accelerator has an integrated pedal travel sensor. The driver request is sent to the vehicle management computer via a PWM (pulse-widthmodulated) signal.

The CR fuel injection system consists of a quantity-controlled high-pressure pump that can produce a very high fuel pressure (max. 1800 bar) in a fuel reservoir, the "rail". The rail makes this pressure available to the "fuel injector" for finely atomised injection.
The main characteristic of CR systems is therefore the fact that pressure generation and fuel injection from the rail are separated. This time-controlled fuel injection system therefore overcomes the typical restrictions of conventional camcontrolled systems. The increased average fuel injection pressure and injection timing can be freely selected over a wide range independently of the engine operating point. The quantity-controlled high-pressure pump, which is fed by a flanged-on predelivery pump, delivers as much diesel fuel as required to the rail until the desired fuel pressure is reached. This pressure accumulator is connected via hydraulic lines with the fuel injectors. The fuel injectors are controlled by solenoid valves and inject a quantity of the stored fuel defined by the control unit into the combustion chambers of the engine. This allows optimisation of the combustion process.
The hydraulic components of the fuel injection system are monitored by the control unit. The sensors of the control unit continuously measure data relating to engine and vehicle operation. For example, the rail pressure sensor, control unit and quantity-controlled high-pressure pump form a control loop to produce the desired rail pressure. Other sensors, such as coolant temperature sensor, charge air temperature sensor or atmospheric pressure sensor, help to optimally adapt the engine to changing ambient conditions.

Exhaust gas recirculation (EGR)
Cooled and regulated exhaust gas recirculation systems are installed in engines from Euro 3. These systems reduce formation of nitrogen oxide. The exhaust gas mixed with the intake air reduces the oxygen concentration in the charge gas and increases its temperature. Both these factors reduce the combustion temperature and formation of nitrogen oxide. This also reduces the quantity of exhaust gas. If too much exhaust gas is recirculated, soot and carbon monoxide emissions increase due to the lack of oxygen. The recirculated quantity of exhaust gas must be restricted so that sufficient oxygen remains for combustion.
Function: The exhaust gas is routed to the turbocharger in separate exhaust manifolds (cylinders 1,2,3 and 4,5,6). The exhaust gas is routed from 2 outlet points (1st outlet from cylinders 1,2,3 and 2nd outlet from cylinders 4,5,6) in separate pipes through a heat exchanger connected to the cooling circuit. The cooled exhaust flow is brought together only after the check valves at the end of the heat exchanger. This separate exhaust gas routing results in a pulsating exhaust gas flow, which is required to overcome the charge pressure in the intake manifold. The quantity of recirculated exhaust gas can be restricted or interrupted (engine braking mode) by means of the electro-pneumatically controlled shutoff flap. This is controlled by the EDC control unit. The charge air temperature sensor is located in the intake manifold. This is used to switch off EGR as required in order to ensure that the intake air does not become too hot. ChargeEngine

New engine generation D20 Common Rail + cooled exhaust gas recirculation + MAN PM-KAT
The MAN PM-KAT filter is a continuously operating particulate matter separating system featuring open channels
Particulate separation is effected by specially triggered turbulence during the deflection of exhaust gases in the separator and their passage through the sintered metal fabric.
The dissolution of the particulates retained in the fabric is the result of the permanent chemical reaction brought about with the aid of the NO2 formed in the upstream oxidising catalytic converter.
As a result, the MAN PM-KAT is maintenance-free and does not clog up. In addition, an above-proportional amount of the smallest particulates (< 40 nm) is eliminated.

Two-stage turbocharging
The principle of two-stage turbocharging allows generation of very high boost pressures. In the upper rpm range, these pressures would lead to overloading of the engine (particularly cylinder pressure) as well as of the peripheral devices (e.g. charge air cooler). For this reason, it is always necessary to limit the boost pressure. In the simplest case, this is done by a pressure-loaded and springloaded waste gate that limits the boost pressure above a certain fixed value. The D0834 LFL 42 additionally features a boost pressure control valve controlled by the electronic engine controller (EDC). This makes it possible to achieve an optimum boost pressure characteristic.

Cab operation The CAN bus structure Background: Many open-loop and closed-loop control operations must nowadays be performed by electronic control units, since mechanical or electrical control systems do not offer the required level of performance. The electronic control units require information to perform all the tasks reliably, and they receive this from connected sensors as well as from other control units. To minimise the number of sensors required in the vehicle, the goal is to measure each measured value (e.g. water temperature, engine) only once, and to then make this measured value available to all control units.
In the TG series, the control units are connected by means of a data network, the CAN network (CAN = Controller Area Network, BUS = Binary Unit System).

This means that existing operating elements for control, delivery, distribution, temperature adjustment and air cleaning can also be used for operation of the auxiliary system when the vehicle is stationary.
Cold accumulator
Expansion tank Air-conditioning unit with heat sink Evaporator unit
Control and distribution unit
The combined driving and auxiliary air-conditioning system increases operating safety and economy in addition to enhancing driver comfort and performance. The best possible air distribution in the cab is achieved with a low noise level through utilisation of the optimised air routing of the vehicle air-conditioning system for the auxiliary system as well. This means that no additional air ducts are necessary.
LF-02a[1]. TG-allg.-05-Fahrerhaus-0805 FH-en.doc
5.13
Air conditioning during break and waiting times When the engine is switched off, cold is supplied by the accumulator, which stores excess cold while the vehicle is moving. During operation of the auxiliary airconditioning system, the fan and control functions of the vehicle air-conditioning system remain active; this means that the driver does not need to adjust or change anything. Air conditioning while sleeping Sleeping in the vehicle is no longer a problem even during very warm or sultry nights thanks to the auxiliary air-conditioning system, which also de-humidifies the air. In order to ensure that it does not become too cold in the cab as the night temperatures fall, the control system first reduces the cold supply and then fully switches off the accumulator if the temperatures fall further. If this is not sufficient to prevent excessive cooling, the fan is operated only periodically. However, an adequate supply of fresh air is always guaranteed.

Automatic functions:
Activation in brake pedal lead travel Retarder stages are integrated in the free travel of the brake pedal (approx. 25 % of the total actuating range). The service brake is not yet active in this range. The amount of activated retarder torque depends on the vehicle load. It is a maximum of 50 % of the maximum torque, but without engine brake operation. The retarder icon is additionally shown on the display.

Automatic braking function with cruise control operating lever
The automatic braking function is used to inform the FFR of a desired speed. In conjunction with the FFR and engine CAN, the EDC system regulates the vehicle speed to the desired speed (as long as the engine power is sufficient for this). The automatic braking function is activated 4km/h above the set cruise control speed. The speed threshold of 2 km/h is defined as part of EOL parameterisation and can be changed by the service organisation. The FFR manages this function and the braking power of the retarder/intarder or of the engine brake is increased, depending on the engine load.
Activation by adaptive braking
A further comfort function is provided by the brake pedal. When the vehicle is braked with the brake pedal, the speed is stored at which the brake pedal is released (= adaptive braking). The speed is stored and is maintained as the new speed by the automatic braking system as long as the required braking torque of the retarder is sufficient. This function is deactivated when the accelerator is pressed or the cruise control stalk is operated.
Activation by the accelerator
A further comfort function is available when the accelerator is in normal position. The current vehicle speed is saved and the vehicle is automatically braked if the speed exceeds the current speed by 4 km/h. This function is deactivated again when the accelerator or brake pedal is pressed or the cruise control stalk is operated.

Switch: FGR (cruise control) / FGB (speed limiter) / ACC switchover
Function:
The FGR/FGB/ACC (cruise control/speed limiter/ACC) switch is used for switching from the cruise control function to the speed limiter function. Cruise control (FGR): The switch FGR/FGB/ACC (button 10) must be set to the FGR function. It is possible to set a desired speed with the cruise control stalk switch A429. The cruise control function is also deactivated if the driver presses the brake pedal (signal from EBS via T-CAN) or clutch pedal (signal from clutch travel sensor B362).
Speed limiter (FGB)
The switch FGR/FGB/ACC must be switched to the FGB function. Using the cruise control stalk switch A429, it is possible to set a maximum speed that cannot be exceeded. An icon appears on the display when the maximum speed is reached. The speed limiter function is not switched off but is temporarily interrupted when the accelerator is pressed hard (e.g. to overtake, like with kick-down). The speed limiter is activated again when the current vehicle speed falls below the speed limit.

When the vehicle is stopped, the current gear or the gear selected by the DNR switch is maintained as the gear for driving off, depending on which is the lower gear.
Emergency functions in the event of failure Automatic mode is activated if the cruise control/gearbox switch fails. If the DNR switch fails, it is possible to shift from forward gears via neutral to reverse gears and vice versa with the cruise control/gearbox switch. Autoskip function: If the engine speed falls below a certain limit (900 rpm) in manual mode, it is possible to skip several gears by "Downshift" (hold) operation. The gear recommended by the transmission control is then engaged.
In position "D" , the TipMatic selects the starting gear depending on the current vehicle load (standard starting gear = D3)!

Manoeuvring position ("DM" and "RM"): In Manoeuvring mode, the whole travel of the accelerator is used to close the clutch; the engine speed is limited to 850 rpm. The manoeuvring gears "DM" and "RM" are for extremely slow driving, e.g. when coupling and uncoupling a semitrailer or trailer. Overview of switch variants: Switch, 7-stage, for TipMatic 4x2, 6x2, until May 2004 Buses, rigids also after 2004
Switch, 5-stage, for TipMatic 4x2, 6x2, from June 2004 In position "D", the TipMatic gearbox automatically selects the starting gear depending on the vehicle load (standard starting gear = D3) Switch, 6-stage, for TipMatic 6x4, 8x4, 8x2, 6x2, 4x4, 6x6, refuse collection vehicles
Switch, 6-stage, for TipMatic "Offroad" 4x4, 6x6, 8x6, 8x8

Towing and tow-starting The drivetrain to the drive axles must always be disconnected for towing! This can be done by removing the propshaft or axle shafts.
Tow-starting AS-Tronic
Tow starting of the engine is not possible!
Roller test bed After driving into the test bed rollers, the gearbox must be shifted to “Neutral”, otherwise the AS-Tronic control unit will detect a “moving vehicle” and close the clutch. The vehicle may then independently drive out of the test bed rollers!
