The wheel hub motor device has the advantages that the structure is simple, the implementing of technique is easy, and the integration with the whole automobile is convenient.
Description
technical field [0001] The invention relates to the structural field of hub motors, in particular to a hub motor device and an automobile that output large torque. 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 battery to provide elec...
