Abstract

The invention relates to a power machine assembly used for an electric vehicle, and belongs to the technical field of electric drive system structures. The power machine assembly comprises a motor hollow gear shaft connected with a hollow shaft motor; the motor hollow gear shaft is connected with a motor gear sleeve through a spline; the motor gear sleeve is engaged with a bull wheel (7) of a stepped gear arranged on a gear supporting shaft through a gear structure; a small wheel of the stepped gear which is integrated with the bull wheel of the stepped gear is also arranged on the gear supporting shaft; the small wheel of the stepped gear is engaged with an inner gear through the gear structure; the inner gear is connected to a differential mechanism shell through the spline; a differential mechanism is arranged in the differential mechanism shell; and the differential mechanism is linked with a half shaft. By using the power machine assembly used for the electric vehicle, the structure is simple, the noise is low, the efficiency is high, the resonance vibration is small, the start is fast, and energy saving is realized.

Description

technical field [0001] The invention relates to a power machine assembly for an electric vehicle, belonging to the technical field of electric drive system structure.
