Abstract

The invention discloses a wheel-side driving structure, a wheel-side driving assembly and a vehicle, the wheel-side driving structure comprises a planetary gear train, a driving motor unit and an adjustable-speed motor unit, the planetary gear train comprises a sun gear, a gear ring and a planet carrier for driving wheels, and the adjustable-speed motor unit is in transmission connection with the sun gear; the driving motor unit is in transmission connection with the gear ring; or the planetary gear train comprises double planet carriers for driving the wheels, and a small sun gear and a large sun gear of which the rotating axes coincide, the speed regulating motor unit is in transmission connection with the small sun gear, and the driving motor unit is in transmission connection with the large sun gear. The wheel-side driving assembly and the vehicle comprise a left wheel-side driving structure and a right wheel-side driving structure which share the driving motor unit, and the left wheel-side driving structure and the right wheel-side driving structure both comprise the wheel-side driving structure. The wheel edge driving structure is simple and compact in structure and good in installation performance, the average efficiency of the wheel edge driving assembly and the vehicle is high, and the cost is relatively low.

Description

technical field [0001] The present invention relates to the technical field of wheel-side drive structures, in particular, to a wheel-side drive structure, a wheel-side drive assembly and a vehicle. Background technique [0002] With the development of vehicle technology, electric vehicles are becoming more and more popular. For example, the four-wheel independent drive system of an electric vehicle uses four motors to drive the four wheels of the vehicle independently, and the torque and speed of the four wheels can be precisely controlled independently of each other, which brings a series of advantages, such as realizing more Small radius turning, auxiliary ESP function, auxiliary steering function, auxiliary braking function, etc. Existing four-wheel independent drive systems are generally bulky, heavy and costly. SUMMARY OF THE INVENTION [0003] The purpose of the present invention is to provide a wheel-side drive structure, a wheel-side drive assembly and a vehicle...
