Abstract

The invention discloses a wheel hub motor device capable of outputting high torque. The wheel hub motor device comprises a wheel hub motor, a first planetary gear row, a second planetary gear row and a wheel rim, wherein the wheel hub motor is provided with a motor outer casing; the first planetary gear row comprises a first sun gear, a first planetary carrier and a first inner gear ring; the first gun gear fixedly sleeves a motor shaft of the wheel hub motor; the second planetary gear row comprises a second sun gear, a second planetary carrier and a second inner gear ring; the second sun gear is connected with the first planetary carrier, and rotates together with the first planetary carrier; the second sun gear is rotationally supported on the motor shaft of the wheel hub motor; the first inner gear ring is fixedly connected with the second planetary carrier, and the second inner gear ring is fixedly connected with the motor outer casing; the wheel rim is connected with the secondary planetary carrier, rotates together with the second planetary carrier, and is used for outputting rotation power. The invention also discloses an automobile. 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...
