Abstract

The invention relates to a steering driving wheel, and belongs to the field of electric automobiles. The steering driving wheel comprises an unequal length double-cross-arm suspension, a driving motor, a steering motor, a universal transmission shaft, a worm gear reducer, a small bevel gear, a transmission bevel gear, a large bevel gear, a pair of braking calipers and automobile wheels, wherein both the driving motor and the steering motor are fixedly connected to an automobile frame, the driving motor drives the automobile wheels to rotate in a transmission mode through the universal transmission shaft and the gears, and the steering motor achieves steering of the automobile wheels through the universal transmission shaft and the worm gear reducer. When an automobile turns, mutually independent operating of a driving system and a steering system can be achieved through reasonable controlling of rotation speed of the driving motor. While the steering driving wheel achieves large-angle steering and driving of the automobile wheels, unsprung mass of the automobile wheels is further reduced, and flexibility and driving smoothness of the automobile are improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, in particular to a steering drive wheel that can be used for electric vehicles. 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 transmission angle, it generally cannot Large ...
