Unequal double-wishbone suspension wheel side driving device capable of achieving large-angle steering

Abstract

The invention relates to an unequal double-wishbone suspension wheel side driving device capable of achieving large-angle steering and belongs to the field of electric automobiles. The unequal double-wishbone suspension wheel side driving device capable of achieving large-angle steering comprises an unequal double-wishbone suspension, a driving motor, a steering motor, a universal transmission shaft, a worm and gear reducer, a bevel pinion, a transmission bevel gear, a bevel gear wheel, a brake caliper, an axle housing and wheels, wherein the driving motor and the steering motor are both fixedly arranged on an automobile frame; the driving motor drives the wheels to rotate through the universal transmission shaft and gear transmission; the bevel gear wheel simultaneously plays the role of a brake disc; and the steering motor achieves steering of automobiles through the universal transmission shaft and the worm and gear reducer; the transmission bevel gear is sleeved on a master pin in empty mode; and a worm gear is connected with the master pin through a flat key. When automobiles steer, mutually independent operation of a driving system and a steering system can be achieved by reasonably controlling the rotate speed of the driving motor. The unequal double-wishbone suspension wheel side driving device capable of achieving large-angle steering not only achieves large-angle steering, but also reduces the unsprung mass of the automobiles, and improves the flexibility of the automobiles and riding comfort.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to an unequal-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. Most of the steering systems of electric vehicles follow the linkage-type steering trapezoidal mechanism of traditional vehicles. Since the steering trapezoidal mechanism is limited by the transm...

Problems solved by technology

However, in this type of technology, electric wheel drive is used. Due to the complex structure of the wheel mechanism of the electric wheel and the large unsprung mass, the size and quality of the motor are greatly limited, which seriously affects the performance of the electric vehicle.
