Abstract

The invention relates to the technical field of drive axle reducers and discloses a drive axle reducer for an integrated motor. The reducer comprises a shell body, a driving bevel gear and a driven bevel gear, wherein the shell body defines an installation cavity, and a sun gear and a planet carrier assembly are arranged in the installation cavity; a sun gear installation hole is formed in the center of the planet carrier assembly, and the sun gear is arranged in the sun gear installation hole and fixed on the planet carrier assembly; the planet carrier assembly is further provided with a plurality of planetary gear installation holes circumferentially distributed around the sun gear installation hole, planetary gears are arranged in the planetary gear installation holes, and the planetarygears mesh with the sun gear; the driving bevel gear is fixed on the planet carrier assembly and configured to rotate along with the sun gear; and the driven bevel gear meshes with the driving bevelgear and is fixedly connected to a differential assembly. According to the drive axle reducer for the integrated motor, the planetary gear, the driving bevel gear and the driven bevel gear are provided additionally and connected to the sun gear in series, so that speed reducing ratio of the drive axle reducer is increased, output torque of the driven bevel gear is increased, and the whole vehiclematching requirement is met.

Description

technical field [0001] The invention relates to the technical field of drive axle reducers, in particular to a drive axle reducer with an integrated motor. Background technique [0002] In domestic electric vehicle axles, since the motor power is directly transmitted to the wheels through the axle, the original gearbox structure is canceled and a large deceleration ratio is required. At present, two pairs of cylindrical gears are mostly used for deceleration, or a pair of cylindrical gears and a pair of bevel gears are used for deceleration. The deceleration of these two structures is relatively small, and the maximum output torque often cannot meet the matching requirements of the whole vehicle. Contents of the invention [0003] Based on the above, the purpose of the present invention is to provide a motor-integrated drive axle reducer, which solves the problems in the prior art that the reduction ratio is small and the maximum output torque cannot meet the matching requ...
