Abstract

The invention discloses a new energy electric vehicle rear drive direct-connected speed reducer, belongs to the technical field of new energy electric vehicle speed reducers, can cooperate with an electric vehicle drive motor to run in all working conditions from low speed to high speed, and solves the problems that the assemble of the structure of an existing speed reducer is complicated and difficult, the maintenance is inconvenient, the noise is excessive, the abrasion is serious, the lubrication and cooling are insufficient, and the service life is short. The speed reducer comprises a speed reducer shell body, a power input assembly, a middle transmission assembly and a differential device assembly; the middle transmission assembly and the power input assembly are arranged in the speedreducer shell body in sequence from the right side; the differential device assembly is arranged in the speed reducer shell body from the lower side, and the formed speed reducer is in direct-connected assembly with an electric vehicle rear axle housing and left and right half shafts. The new energy electric vehicle rear drive direct-connected speed reducer has the advantages that the structure is simple, the transmission efficiency is high, the assembly and maintenance are convenient, and the cost is low.

Description

technical field [0001] The invention relates to the technical field of a rear drive reducer for a new energy vehicle, in particular to a rear drive direct-coupled reducer for a new energy electric vehicle. Background technique [0002] With the promotion and implementation of the national new energy vehicle strategy, the new energy vehicle market has ushered in a period of rapid development. The power characteristics of the driving motor of new energy electric vehicles determine that the traditional automobile gearbox is not suitable for the functional requirements of new energy electric vehicles; the main advantages of electric vehicles are low noise and zero emission, so the main mechanical transmission part of electric vehicles - reducer noise , Maximizing the battery life is the key to the electric vehicle reducer. With the rapid development of the new energy vehicle market, more and more electric vehicle reducers appear on the market. Some products have problems such as...
