3. EHPS OUTLINE EHPS (Electronically Controlled Full Hydraulic Power Steering) is adopted in some counterbalanced electric powered forklift models (5FBE, FBMF, etc.). A mechanism that electronically controls the pump motor rotation for hydraulic pressure generation is added to the hydrostatic type power steering to make the motor run only during steering operation so as to save energy. When the steering wheel is rotated, the rotating torque is detected by a torque sensor which sends an electric signal to the controller. The controller receives the signal and sends the corresponding chopping instruction for motor rotation to a transistor. The hydraulic components of the hydrostatic type power steering mechanism in the EHPS are not explained here because they are almost the same in structure and function with those explained elsewhere. The chopping control for motor rotation varies with the model. It is roughly classified into the type using an electrical torque sensor (FBMF series) and the type using an oil pressure switch at the steering oil control valve (5FBE series).

1) Torque Sensor The torque sensor consists of the mechanical block that provides displacement between the input and output shaft rotation angles according to the rotating torque generated by steering wheel rotation and the sensor block that generates an electric signal according to the angle displacement. The mechanical block consists of the input shaft directly rotated by the steering wheel rotating torque, output shaft connected to the power steering control valve, and the leaf spring for retaining the neutral position.

When the steering wheel is in its neutral position, the input and output shafts are held in the neutral position by the leaf spring. When the input shaft is rotated by the steering wheel, the output shaft is not rotated immediately because of the reaction force from the tires transmitted through the control valve. As a result, an angle difference is generated. This difference is converted to an electric signal in the sensor block explained below.

Oscillation circuit B
The sensor block consists of the resonance circuit and the sensor circuit. In the sensor circuit, an electrical vibration (oscillatory current) flows through coil 1-1 in each of oscillation circuits A and B. When the oscillatory current flows through coil 1-1, a current is generated in coil 2 by the induced electromotive force and it flows through the resonance circuit including coil 3 and a capacitor. In the resonance circuit, variation in the positional relationship between coil 3 and the core (due to torsional angle difference between the input and output shafts) changes the oscillation frequency and amplitude. As a result, coil 1-2 provided opposite to coil 2 can receive a signal corresponding to the positional relationship between coil 3 and the core. In this way, the sensor circuit provides an output representing the torsional angle difference between the input and output shafts. Two pairs of resonance circuits are provided on the shafts, to which oscillation circuits A and B correspond. This configuration minimizes the influence of temperature on the torque sensor characteristic.
