Abstract

The invention discloses an electric wheel hub with a wheel edge reduction gear. The electric wheel hub comprises a wheel hub main shaft, a wheel hub, a wheel hub motor and the wheel edge reduction gear, wherein the wheel hub is in running fit with the wheel hub main shaft; the wheel hub motor and the wheel edge reduction gear are arranged in the wheel hub; the wheel edge reduction gear comprises a center gear in running fit with the wheel hub main shaft, an inner gear ring and a plurality of duplicate gears; the inner gear ring is coaxially fixed to the wheel hub; the plurality of duplicate gears are distributed around the wheel hub main shaft; the center gear is used for distributing power output by the wheel hub motor to rack wheels of each duplicate gear; and a pinion of each duplicate gear is meshed with the inner gear ring. The fixed-shaft electric wheel hub is simple in structure, compact in component assembly, high in support stiffness, large in reduction ratio, high in power and relatively long in service life, and has a good lubricating function.

Description

technical field [0001] The invention belongs to the field of electric wheel hub driving devices, and in particular relates to an electric wheel hub with a wheel-side reduction device. Background technique [0002] The wheel reducer is to improve the driving force of the car to meet or correct the power matching of the entire transmission system. The wheel-side reducer currently used is an additional set of gear transmissions that reduce speed and increase torque to meet the power matching needs of the entire transmission system. Installed at the power output terminal of the vehicle to reduce the load on the gearbox. Most of the existing wheel speed reducers adopt planetary gear structure and bevel gear structure. The sun gear of the planetary gear reduction mechanism is used to receive the power input of the motor, and the planet carrier of the planetary gear mechanism is used to output the power. The gearbox of this moving shaft reduction mechanism The structure is comple...
