Abstract

The invention discloses a dual-motor synchronous-driving steering actuator of an automobile steer-by-wire system. The dual-motor synchronous-driving steering actuator aims at improving the steering actuating response characteristics and life of the steer-by-wire system and the structural redundancy safety and structural compactness of a steering actuating system. The dual-motor synchronous-driving steering actuator comprises two same steering motors, two same worm-gear reducer assemblies, torque angle sensors and a rack and pinion steering gear assembly. According to the dual-motor synchronous-driving steering actuator, the dual motors and the worm-gear reducer assemblies which are reversely and symmetrically arranged are adopted, the two steering motors and worm-gear reducers assembled with the steering motors are meshed with racks of rack and pinion steering gears, and the torque angle sensors are embedded into the worm-gear reducer assemblies.

Description

technical field [0001] The invention belongs to the field of automobiles, and relates to an actuator of an automobile steering system by wire, in particular to an actuator by wire of an automobile synchronously driven by double motors. Background technique [0002] Traditional steering systems (mechanical, hydraulic and electric power steering systems) ensure that the car moves according to the driver's will, but because of its fixed steering ratio, the car's response characteristics vary with the speed and steering wheel angle, so the driver must Compensating for changing characteristics ensures that the car behaves as intended under different operating conditions. But this affects the handling stability and driving comfort of the car. Therefore, the steer-by-wire system came into being. The steer-by-wire system can freely design the force transmission characteristics and angle transmission characteristics of the steering system, which brings a lot of room for development...
