An Equal-length Double Wishbone Suspension Wheel Side Drive Device Capable of Large Angle Steering

Abstract

The invention relates to an equal-length double-crossarm suspension wheel rim driving device capable of realizing large-angel steering, belonging to the field of electric automobiles. The device comprises an equal-length double-crossarm suspension, a driving motor, a steering motor, a belt wheel with a changeable pitch, a steering belt, a driving belt wheel, a steering belt wheel, a small bevel gear, a large bevel gear, a main pin, a bridge shell, a braking clamp and wheels. The connection lines of the main shaft and upper and lower crossarms and the connection lines of the upper and lower crossarms and an automobile frame hinging point form a parallelogram; the driving motor and the steering motor are both arranged on the connection lines of the upper and lower crossarms and the automobile frame hinging point and fixedly arranged on an automobile frame; the driving motor is used for driving the wheel through belt driving and gear driving; the large bevel gear also serves as a braking disc; the steering motor realizes the steering of an automobile through belt driving; the driving belt wheel and the small bevel gear are both sleeved on the main pin; and the steering belt wheel is connected with the main pin through a flat key. When the automobile steers, the rotating speed of the driving motor is controlled reasonably so that a driving system and a steering system can work independently.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to an equal-length double-wishbone suspension wheel-side driving device capable of large-angle steering. Background technique [0002] In recent years, with the increasingly serious energy crisis and the continuous enhancement of people's awareness of environmental protection, the requirements for automobiles are getting higher and higher. Electric vehicles have incomparable advantages over traditional vehicles in terms of energy saving, environmental protection and performance, and have become the mainstream of new energy vehicle development recognized around the world. At present, the design of electric vehicles at home and abroad is mostly modified on the basis of traditional vehicles. The steering system of electric vehicles mostly adopts the connecting rod steering trapezoidal mechanism of traditional vehicles. Since the steering trapezoidal mechanism is limited by the transmis...
