Problems solved by technology

Its disadvantages are: because the wheel shaft is under unilateral force, it will cause the wheel shaft to run unsteadily and affect the service life of the components; in addition, the single-motor input method must require a large modulus of the driving bevel gear and the driven bevel gear , not only will affect the smoothness of the transmission, but also will generate a lot of noise

Abstract

The invention relates to a double-motor input wheel-side speed reducer for an electric bus. The double-motor input wheel-side speed reducer comprises a planetary gear speed reducer arranged in a wheel, wherein a wheel shaft is arranged in the planetary gear speed reducer; a driven bevel gear is arranged on the wheel shaft; two driving bevel gears are arranged on the outer side of the driven bevel gear and meshed with the driven bevel gear; meshed points between the two driving bevel gears and the driven bevel gear averagely divide the circumference of the driven bevel gear; and each driving bevel gear is driven by a driving motor. The double-motor input wheel-side speed reducer provided by the invention is suitable for electric buses.

Description

technical field [0001] The invention relates to a double motor input wheel side reducer for an electric passenger car. Background technique [0002] At present, the wheel reducer used in electric passenger cars is usually input by a single motor, which realizes the operation of the wheel shaft through a drive motor arranged on the side of the wheel shaft, through the transmission of the driving bevel gear and the driven bevel gear. Its disadvantages are: because the wheel shaft is under unilateral force, it will cause the wheel shaft to run unsteadily and affect the service life of the components; in addition, the single motor input method must require a large modulus of the active bevel gear and the driven bevel gear , not only will affect the smoothness of the transmission, but also will generate a lot of noise. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a dual-motor input wheel side reducer for electric ...
