Vehicle, driving system thereof, and vehicle driving wheel

Abstract

The invention provides a vehicle, a driving system thereof, and a vehicle driving wheel. The vehicle comprises a frame and a driving system. The driving system comprises the vehicle driving wheel anda driving motor used for driving the vehicle driving wheel to rotate. The vehicle driving wheel comprises a vehicle hub. An inner gear ring is integrally machined on the wall of an inner hole of the vehicle hub, a planet wheel, a planet carrier and a sun wheel which are matched with the inner gear ring are arranged in the inner hole of the vehicle hub, the sun wheel is provided with a connecting end in transmission connection with the driving motor, and the inner gear ring, the planet wheel, the planet carrier and the sun wheel form a planet gear train. By means of the structural advantages ofthe planetary gear train, the large transmission ratio and the large output torque are achieved; and the planetary gear train is arranged in the hub, so the space in the hub is fully utilized, and the space outside the hub is saved, thereby the problem that due to the fact that the transmission ratio and the output torque are increased, the structure is too large, and the installation space is insufficient is solved.

Description

technical field [0001] The invention relates to a vehicle, its drive system and vehicle drive wheels. Background technique [0002] With the increasing shortage of global energy and the continuous deterioration of the environment, in order to save energy and reduce vehicle exhaust emissions, many countries around the world are vigorously developing and promoting electric vehicles. Electric vehicles can not only save energy and reduce emissions, but also improve the comfort of people in cars. It can also solve the problem of energy shortage. [0003] The traditional fuel-powered bus adopts the central direct drive mode, that is, the power of the engine is transmitted to the axle through the transmission and the drive shaft, and then transmitted to the tires through the axle reducer, differential, and half shaft. For traditional electric buses, the engine is only changed to a motor, and the form of power transmission remains unchanged. If you want to design a bus from the pe...
