Title:
MULTI-FUNCTIONAL ELECTRIC RECIRCULATING BALL STEERING SYSTEM FOR COMMERCIAL VEHICLE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2022/227601
Kind Code:
A1
Abstract:
A multi-functional electric recirculating ball steering system for a commercial vehicle, and a control method therefor. The system comprises: an electric power assisting module, a mechanical transmission module, and a control module. The electric power assisting module comprises: a dual-rotor motor module (14) and an assist motor (22).The mechanical transmission module comprises: a steering wheel (1), a steering shaft (4), a shaft coupling (5), a recirculating ball steering gear (16), a sector gear (19), a sector gear shaft (6), a steering drag link (7), a steering tie rod (12), a steering knuckle arm (8), a left trapezoidal arm (11), a right trapezoidal arm (26), a left steering knuckle (10), a right steering knuckle (25), a left wheel (9), and a right wheel (24). The control module comprises: an electronic control unit (21), a torque sensor (3), a vehicle speed sensor (20), an angle sensor (2), and a current sensor (23). By means of the present system, the high reduction ratio capability of the recirculating ball steering gear (16) is fully utilized, the system assist torque is maximized, the electric power assistance function is achieved, the system is simplified, and the reliability of the system while providing a wire control function is ensured.
