Abstract

The invention provides a drive-by-wire independent steering-driving integrated double wishbone suspension system based on a double crank mechanism. The drive-by-wire independent steering-driving integrated double wishbone suspension system based on the double crank mechanism comprises a wheel steering angle sensor, a worm gear reducer, a servo motor, a bracket, an upper swinging arm, a driving rod, a driving rod ball, a connecting rod, a lower swinging arm, a lower swinging arm ball stud, a hub, a driven rod ball, a steering knuckle, a driven rod, an upper swinging arm ball stud, a PID (Proportion Integration Differentiation) controller and a CAN bus system. The invention is advantaged in that a steering mechanism does not occupy additional space during realizing drive-by-wire four-wheel, the steering error is furthest reduced, the adverse effect of the wheel hop on the working state of a decelerating device when a vehicle runs on a complicated pavement can be effectively decreased, and toe-in interference caused by reverse input can be effectively avoided. As steering wheel signal feedback is also included, the closed-loop control of the system can be realized, accurate steering can be realized and the vehicle steering performance can be very well improved. The excellent effects are extremely helpful for the promotion of the drive-by-wire independent steering-driving integrated double wishbone suspension system in the vehicle industry.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to a double-wishbone suspension system based on a double-crank mechanism-based independent steering-by-drive integrated double-wishbone suspension system. Background technique [0002] The rise of new energy vehicles, mainly electric vehicles, provides new ideas for solving the oil crisis and environmental pollution problems. In recent years, the development of in-wheel motors and steering-by-wire technology has attracted great attention. Compared with the previous generation of electric power steering system, the steering-by-wire system has better operational stability. Since the steering wheel and the steering wheel do not need to be connected by a mechanical mechanism, on the one hand, it gets rid of some installation and positioning restrictions of the steering system itself, and on the other hand, it also gets rid of the motion interference between the ste...
