Abstract

The invention discloses an electric wheel assembly device for an overload vehicle. The electric wheel assembly device comprises a hub motor and a two-stage planetary gear reducer, wherein the hub motor comprises a left motor casing, a right motor casing, a motor rotor, a stator coil and a motor shaft; the two-stage planetary gear reducer comprises a first-stage planetary gear pair and a second-stage planetary gear pair; the first-stage planetary gear pair comprises a first-stage sun gear, a first-stage planetary gear, a first-stage planetary shaft, a first-stage planetary carrier and a first-stage inner gear ring; and the second-stage planetary gear pair comprises a second-stage sun gear, a second-stage planetary gear, a second-stage planetary shaft, a second-stage planetary carrier and a second-stage inner gear ring. The invention further discloses the vehicle. The electric wheel assembly device has the advantages that the structure is simple, the technology is easy to implement, and meanwhile, integration is convenient to achieve by the electric wheel assembly device and the finished vehicle.

Description

technical field [0001] The invention relates to the field of electric wheel structure, in particular to an electric wheel assembly device for a heavy-duty vehicle and an automobile. Background technique [0002] Electric vehicles include hybrid vehicles, fuel cell vehicles, pure electric vehicles, etc., which have the characteristics of energy saving and environmental protection, and are the development direction of the new generation of automobile technology. The electric vehicles currently being developed are generally formed by modifying the power transmission system in the traditional automobile chassis. For example, a hybrid vehicle is driven by adding a drive motor to the drive train and realizing power synthesis with the help of a power synthesizer. The fuel cell vehicle uses the electric energy output by the fuel cell and the electric energy of the auxiliary energy to provide power for the drive motor to drive the vehicle. A pure electric vehicle uses a power batte...
