Abstract

The invention relates to a disc-type servomotor direct-driving device suitable for self-adaptable power-assisted steering of an automobile. The disc-type servomotor direct-driving device comprises a rack shaft, wherein the right end of the rack shaft is connected with the other end of a right horizontal pull rod through a first power-assisting motor connecting mechanism or a second power-assisting motor connecting mechanism; a torque sensor installed on a steering column is connected with a disc-type motor of the first power-assisting motor connecting mechanism or the second power-assisting motor connecting mechanism through an electronic control unit; and power provided by the disc-type motor for steering is adopted to reduce the hand power of an operator for steering, and when the operator rotates a steering wheel leftward or rightward, the first power-assisting motor connecting mechanism or the second power-assisting motor connecting mechanism provides the rack shaft and the right horizontal pull rod with power for leftward movement or rightward movement, so as to enable s left steering wheel and a right steering wheel to rotate. The disc-type servomotor direct-driving device provided by the invention has the advantages of simple mechanism, small occupied space and quick response speed.

Description

technical field [0001] The invention relates to the field of automobile steering systems, in particular to a disc servo motor direct drive device suitable for automobile adaptive power steering. Background technique [0002] The electric power steering system (EPS) is based on the traditional mechanical steering system, according to the torque signal acting on the steering wheel and the vehicle speed signal, the electronic control device makes the motor generate an auxiliary force of corresponding magnitude and direction to assist the driver A servo system that performs steering operations and obtains the best steering characteristics. The electric power steering system can provide the best power assistance under various driving conditions, reduce the disturbance to the steering system caused by uneven road surfaces, improve the steering characteristics of the car, reduce the steering force when the car is running at low speed, and improve the speed of the car when driving a...
