it (SCU) is fully fluid link ed. This means there is no mechanical connection between the steering unit, the pump and the steering cylinder s. The unit consists of a manually operated directional control servo valve and feedback meter element in a single body. It is used principally for fluid linked power steering systems but it can be used for some servo-type applications or any application where visual positioning is required. The close coupled, rotary action valve performs all necessary fluid directing functions with a small number of moving parts. The manually actuated valve is coupled with the mechanical dri ve to the meter gear. The control is lubricated and protected by the power fluid in the The Char-Lynn®

Pump flow not used for

When not
steering, the power beyond unit directs all inlet flow to the auxiliary circuit. However once steering is initiated, part of the auxiliary flow is diverted to steering. Since steering has priority, all flow, if required, will be diverted to steering. The tank port of the steering unit has flow only when steering is operated. Thus, flow out of the auxiliary ( “ PB ” ) port and the tank port will fluctuate or stop depending on steering input.

Neutral Bleed Feature
Closed Center Steering Control Units are available with and without neutral bleed feature. Most applications may not require the bleed feature, however, the maximum temperature
differential between components within the steering circuit must not exceed specification (50 F or 28 C). Order unit with the bleed feature if the temperature differential may exceed this limit. The neutral bleed feature allows a small flow of fluid to pass through the unit when in neutral to reduce the thermal differential. °

Typically, the gerotor between the SCU housing an
the shift
valve is the smaller gerotor (first gerotor). The shift valve is activated by the operator, which allows or prevents flow to the second gerotor. A separate solenoid valve provides the pressure pilot signal to shift the aforementioned valve. The OEM will define and provide the operator switch to activate the solenoid valve. d

The
ing unit operates the same as a traditional hydrost atic steering control unit. Steering (flow) is a function of steering wheel rot ations (rpm). Metered (gerotor) steering provides precise, responsive, and smooth steering. All the flow is metered by the first gerotor, resulting in a greater number of turns lock-to-lock. In case of pressure loss, the shift valve automatically prevents flow to the second gerotor and emergency steering is available via the first gerotor. steer
Metered Steering Mode 2
– The

Description
Manual in
The
dual displacement steering control unit allows manufacturers of off road vehicles to retain manual steering capabilities while reducing the number of components in their system. By using t wo displacements in one unit we offer a better solution to manually steer a vehicle in an unpowered mode without the need of a back-up power system— resulting in a more econom ical machine.

Performance in powered
The
dual displacement ing unit uses two gerotors and a pressure controlled logic valve. The logic valve switches between two displacements, one displacement for manual steering and the tot al of both displacements for powered operation. The logic valve is spring returned to the smaller manual displacement when inlet pressure falls below 8 bar [120 psi]. Above 8 bar [120 psi] the logic valve connects both gerotors to provide full powered displacement.

Eaton Patented Technologies Cylinder Damping
Description
Features
Cylinder damping can help smooth the steering action of large articulated vehicles such as loaders, scrapers, and skidders. These vehicles have overhanging weight with high inertial loads. This energy is dissipated by the cylinder damping orifices which bleed a small amount of flow from the cylinder port to tank.
Three levels engineered to fit your application.
Cylinder Damping has 3 different levels of application. The number of levels equal to the number of Cylinder Damping (CD) orifices. This technology is available on Series 10, Series 20, Series 25, and Series 40. Not all SCUs come with all 3 levels.
Flow Amplification without Cylinder Damping
Benefits
• Reduces jerking motion on medium and large articulated vehicles. • Available on the following steering control units (Series 10, 20, 25, 40).

This is achieved by hydraulically blocking the flow of oil to the gerotor with a shift valve.

Product Description
Eaton’s Series 10 Steering
Control Unit (SCU) facilit ates hydraulic fluid flow like no other unit on the market. This highly-engineered product is the ultimate SCU for mid-range flow applications. Benefits •
The new Series 10 SCU has
unprecedented, continuous pressure rating of 275 bar (4000 psi), making it ideal for heavy-dut y equipment, such as construction and agricultural machiner y. •
an
Its high pressure -
rating re
duces overall equipm ent costs, since smaller cylinder sizes can be assigned into the system. •
The new Series 10
incorporates proven Eaton technologies. An internal, balanced architecture and a widewalled sleeve that is 40% thicker than st andard designs offer increased performance during transient pressure conditions.

Description
The Series 20
steering l unit continues Eaton’s tradition of innovative design and high quality that began with the first fluid linked power steering system.
•
You
•
can count on th s
i steering unit to provide the same smooth, predict able steering as the Char-Lynn steering units that provide dependable, trouble-free steering on applications around the world. •
Provides
m uch
moother steering by minimizing jerky motion on articulated vehicles. s
function
•
Jerk-reducing valves and accumu ators can
l be li i d on most vehicles, providing customer savings through fewer components required and reduced system cost. e m nate
•
S ymmetrical
valving
provides passageways d valving that are equally placed, and pressure areas that are st aged for minimum internal leakage. This results in balance, precise ser vo response and uniform left or right steering action. Eaton’s high
capacity

Steering System Components Brake Valve
loading brake valve makes power brakes an economical and efficient feature on lift Eaton Hydraulics’ sens
trucks.
power brakes in lift productivity, incorporating them into lift trucks has traditionally been expensive. The need for additional flow meant extra plumbing, plus the addition of a dedicated pump or a high pressure accumulator for the brake circuit. The increased system size also meant extra demand on the engine, resulting in reduced fuel economy. While
trucks can aid
brake valve provides a better solution. Used in conjunction with load-sense steering and a priority valve, it can work with an existing system. A dedicated flow source is not required. It also ensures that brakes and steering have priority over the hoist circuit. The Eaton
brake valve has a shuttle in the sensing port which allows the priorit y valve to determine whether brakes or steering require higher pressure. The priorit y valve then shifts to provide adequate flow and pressure for the function with the greatest needs. An Eaton’s new
nte
ra
ress
re
The
design of the circuit also increases efficiency. The control flow line of the circuit is connected in parallel to both the brake valve and the steering unit. Thus, brake and steering pressures are not additive during simultaneous operation. The existing steering pressure is usually enough to provide full power braking.
IN
SS
PS
Another feature
of the
Eaton
brake valve is that it accommodates dead engine braking. The valve contains a large internally cored area that acts as a reser voir, providing oil for brake actuation in the manual mode. The valve design allows the volume and pressure required for manual braking to be generated without excessive pedal force. Thus, the load-sensing brake valve offers the benefits of powered brakes and manual brakes in a single package, eliminating the need for an accumulator.

Before proceeding to evaluation required pump flow the maximum required steering wheel speed must be determined. Typically 120 revolutions per minute (RPM) is used for Rmax. It is import ant at engine low idle condition that the maximum steering wheel speed should be more than 60 rpm. For engine normal idle condition, maximum steering wheel speed should be more =

pm if possible. open center SCU connected with pump directly, maximum pump flow should be less than 1.4 times of SCU rated flow. Higher flow into SCU increases pressure-loss of the steering system. If higher flow is unavoidable, install a flow divider valve into the system or use a load sensing system. r
