TLDR
In this paper, a wheel motor drive axle for electric vehicles is proposed, which consists of an axle case, a motor, a one-stage reducer and a two-stage reduction.Abstract:
The utility model relates to a wheel motor drive axle for an electric vehicle. The wheel motor drive axle for the electric vehicle comprises an axle case, a motor, a one-stage reducer and a two-stage reducer of the same structure as the one-stage reducer. The one-stage reducer and the two-stage reducer respectively comprise a sun wheel, a plurality of planet wheels and a planet carrier. The planet wheels are arranged outside the sun wheels and connected with the planet carriers, and the planet wheels and the sun wheels are fixed through gear rings. The sun wheel of the one-stage reducer is connected with a drive shaft of the motor, the planet carrier of the one-stage reducer is connected with one end of a differential axle, the other end of the differential axle is connected with the sun wheel of the two-stage reducer, and the planet carrier of the two-stage reducer is connected with a hub. The wheel motor drive axle for the electric vehicle has the advantages of being compact in structure, reasonable in design, convenient to install and good in stability, due to the fact that parts such as a gearbox and a differential mechanism required by a centralized motor for driving the vehicle are eliminated, so that a drive system is simplified, the weight of the parts is lightened, and the arrangement of the whole vehicle is benefited.read more
