Prroduct introduction

The pressure sensor of the power steering system detects and controls the pressure value of the high-pressure oil 

flowing into the left or right chamber of the power cylinder when the steering wheel is rotated, 

and transmits the data to the ECU to control the steering high-pressure oil pump; 

The steering wheel simultaneously controls the high-pressure oil driving cylinder to help the steering operation be light and reduce the steering control force of the driver.
