EHP (Electrohydraulic Steering Pump)

PUMPElectro – HEMA Electro Hydraulic Power Steering Pump is designed to be used in electric trucks, buses and tractors.

Depending on the varying demand for hydraulics on the vehicle, PUMPElectro mainly provides the exact amount of oil flow needed in certain pressure levels in order to operate the vehicle hydraulic systems. PUMPElectro consists of a pump, two BLDC type electric motors, two motor drivers, mechanical parts and brackets.

Thanks to the compact structure of PUMPElectro consisting of integrated electronic control unit, it is easy to mount on the vehicle.

Operating Principle:

Based on the hydraulic needs, the motor drivers regulate the electric motor’s speed at certain torque levels.

The vehicle’s primary controller can directly manage the speed of the electric motors and pump through the CAN Bus, or a control function can be added for speed control. The required oil flow is produced by the pump based on displacement and speed.3

Application Fields:

-Steering Systems of Heavy Duty Electric Trucks and Buses

-Steering and Lift Systems of Electric Tractors
