Classification:
Electric-Recirculating-Ball-assist EPS (E-RCB/X-EPS)
Vehicles with front axle weighing less than 2500Kg, Light trucks, Light buses and other logistics cargo vehicles, Assisted autonomous vehicles, etc.
Product Introduction
1.Compact structure, reliable, high stability, high safety, energy saving and environmental protection
2.The gear sector and rack meshing adopts additional radial displacement technology, which makes the gear and rack meshing transmission smooth and smooth without jamming. The meshing point can be accurately controlled at the middle position, effectively eliminating the steering gear gap and improving the ability to return to alignment
3.Applying variable transmission technology, when driving in a straight line at high speed, only a small angle of steering is required, and the steering is precise and the steering stability is good. When driving at a low speed and turning at a large steering angle, the steering is light and labor-saving
4.The power assist is variable with speed: The controller controls the motor assist according to the vehicle speed and steering wheel torque signal to achieve good steering characteristics of light low-speed steering and stable high-speed steering
5.Active backing control: The controller can collect the steering wheel angle, and by controlling the motor, it can achieve active backing control that cannot be achieved by the hydraulic system
6.Performance and fault detection: The controller has a self-test function. lf a fault occurs, it will send a signal to the vehicle instrument panel and send it to the main controller through CAN
