Problems solved by technology

[0003] The existing electric vehicle drive rear axle mostly adopts the transmission structure of motor, secondary reducer and differential, the transmission chain is long, and the structure layout is not compact enough, which makes the transmission efficiency of the whole vehicle low, which is not suitable for the use of micro electric vehicles. When using a first-stage reducer, the first-stage driving gear shaft needs to have the characteristics of low number of teeth and high strength. It is difficult to achieve the desired effect by traditional gear processing methods.
Considering the small internal space and low power storage of micro electric vehicles, the traditional electric vehicle drive rear axle is not completely suitable for micro electric vehicles.

Abstract

The invention discloses a driving rear axle of a mini electric vehicle. The driving rear axle of the mini electric vehicle adopts a transmission structure with a motor, a single-reduction gearbox and a differential, is simple and compact in structure and high in transmission efficiency as compared with the prior art, and is more suitable for mini electric vehicles. Simultaneously, a motor output gear shaft which is processed by a cold extrusion molding technique has the characteristics of low number of teeth and high strength, and is suitable for the transmission structure with the motor, single-reduction gearbox and differential. The motor and reduction gearbox integrated case is convenient for mounting and disassembly, reduces the required space for arrangement, and solves the problem that the inner space of the mini electric vehicle is insufficient.

Description

technical field [0001] The invention relates to a thermal fatigue testing machine applied to the metal bellows of the automobile exhaust system, more specifically, it relates to a kind of independent and combined Motion thermal fatigue testing machine. Background technique [0002] Electric vehicles use vehicle-mounted power batteries as power to drive vehicles. Because electric vehicles have the characteristics of energy saving, environmental protection, lightness, and low operating costs, more and more attention has been paid to them. [0003] The existing electric vehicle drive rear axle mostly adopts the transmission structure of motor, secondary reducer and differential, the transmission chain is long, and the structure layout is not compact enough, which makes the transmission efficiency of the whole vehicle low, which is not suitable for micro electric vehicles. When the first-stage reducer is used, the first-stage driving gear shaft needs to have the characteristics...
