Product Description
Electric Hydraulic Power Steering Pump
The electric Hydraulic Power Steering Pump assembly (hereinafter referred to as the "Steering Pump") is the steering power source for pure electric logistics vehicles, buses, and hybrid buses, providing reliable steering assistance for vehicles, and is the core component of the Steering System. The steering pump consists of a vane pump manufactured in strict accordance with the principles of QC/T299.2 -, a fully enclosed self cooled permanent magnet synchronous motor, and other insulation mechanisms. The main power supply on the vehicle provides power to the permanent magnet synchronous motor through a DC-AC converter. After the circuit is connected, the drive motor operates at a constant rotational speed, which in turn enables the hydraulic pump driven by the motor to provide stable flow to the assist cylinder, ensuring the steering assistance demand at any time. The overall protection level of IP67, minimum volume and weight, excellent noise performance, and stable and reliable performance make our steering pump popular with customers and host manufacturers.
Critical parameters

DARE AUTO is able to design the pump and software according to Customer’s technical specifications. With a robust global engineering team, DARE AUTO is able to provide customized solution.
Better NVH performance
- Motor design: better PMSM electric motor helps to produce required torque while keeping itself quieter.
- Gear Pump design: customized gear pump design helps to improve the NVH performance.
- Electrical hardware: motor position sensing technology helps to reduce torque ripples.
- Control software: precise control algorithms (including sinusoidal motor control) help to reduce the fluid turbulence in the fluid.
Fully conforms to “Quick response” requirement
- Steering velocity is calculated according to the steering angle received.
- A proprietary algorithm  is uesd for quick response to steering maneuvers.
- Steering velocity acceleration rate is also taken into account and utilized to improve the quick response performance.
Less current consumption compared to other equivalent products
- Control algorithm is designed to minimize the chance of generating huge current spikes.
- Motor control phase advance angle is monitored and controlled using current consumption feedback.
- Motor control angle is optimized to reduce current consumption at idle speed.
