Title:
MULTIFUNCTIONAL ELECTRIC CIRCULATING BALL STEERING SYSTEM FOR COMMERCIAL VEHICLE, AND CONTROL METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2023/273643
Kind Code:
A1
Abstract:
A multifunctional electric circulating ball steering system for a commercial vehicle. The system comprises: an electric power assistance module, a mechanical transmission module, and a control module. The electric power assistance module comprises: a dual-rotor electric motor module (14) and an assistance electric motor (22). The mechanical transmission module comprises: a steering wheel (1), a steering shaft (4), a shaft coupling (5), a circulating 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). Further disclosed is a control method for the multifunctional electric circulating ball steering system for the commercial vehicle. The multifunctional electric circulating ball steering system for the commercial vehicle fully uses high reduction ratio capability of the circulating ball steering gear (16), maximizes a system assistance torque, achieves an electric power assistance function, simplifies the system, and ensures the reliability of the system while providing a wire control function.
