Abstract

The invention relates to a reducer assembly for a rear axle of an electric vehicle, and belongs to the field of electric vehicles. An output shaft of a motor is connected with the input end of a first reducer shaft. The output end of the first reducer shaft and the input end of a second reducer shaft are connected through a gear in an engaged mode. The output end of the second reducer shaft and an input shaft of a differential mechanism are connected through a gear in an engaged mode. The input end of the differential mechanism is arranged outside a shell of the differential mechanism through a gear. Reducer shell spigots are arranged at the two ends of the differential mechanism. An oil seal is arranged beside a bearing of the input end of the first reducer shaft. According to the reducer assembly for the rear axle of the electric vehicle, pollution of water and dust to bearings and the like is avoided, noise is reduced, and the service life is prolonged.

Description

technical field [0001] The invention relates to a rear axle reducer assembly, in particular to an electric vehicle rear axle reducer assembly, which belongs to the field of electric vehicles. Background technique [0002] At present, the rear axle of the electric tricycle uses welding to fix the electric vehicle or reducer on the rear axle, and the motor drives the gear plate through the chain, which is linked with the reducer and the differential. The deceleration of this split structure The machine assembly is prone to water and dust in the bearings, and it is not safe, and there are defects such as high noise and short life. Contents of the invention [0003] Aiming at the defects such as high noise and short life of the current reducer assembly driven by chains between the motor and the reducer, the present invention provides a rear axle reducer assembly for an electric vehicle, the purpose of which is to prevent water and dust from entering the connecting shaft etc.,...
