Electric Power Steering Pump System
NFEHPS-1010R1 5311AB
EHPS represents the evolution of conventional hydraulic steering into the electric era, replacing engine drive with an electric motor while retaining hydraulic lines and fluid. The ECU adjusts motor speed in real time based on vehicle speed and steering angle, enabling on-demand flow and pressure for precise assistance. Built on mature hydraulic technology, EHPS delivers robust steering power, making it ideal for light- to heavy-duty commercial vehicles such as buses and trucks.
Quantity:
EHPS, short for Electro-hydraulic Power Steering, is a technology that falls between traditional hydraulic power steering and pure electric power steering. Traditional HPS: Its hydraulic pump is directly driven by the engine via a belt. As long as the engine is running, the pump operates continuously, consuming energy. This is one reason why the steering wheel is heaviest, and fuel consumption increases when traditional gasoline-powered cars are idling. EHPS: It replaces the engine with a dedicated electric motor. This electric motor is specifically designed to drive the hydraulic pump, thereby generating hydraulic power steering.
