Embodiment Construction

[0014] Such as figure 1 , figure 2 shown. A suspension type single-motor electric axle assembly of the present invention includes a mechanical axle 3 , a driving motor 1 and a gear box 2 . Wherein, the mechanical axle 3 adopts the traditional mechanical axle in the drive unit of the traditional pure electric vehicle. The drive motor 1 adopts the motor in the traditional pure electric vehicle drive unit. The gearbox 2 includes a reducer and differential assembly 7 integrated in a gearbox housing 8 . The reducer is a two-stage deceleration reducer composed of the first cylindrical gear 4, the double cylindrical gear 5 and the second cylindrical gear 6. The torque of the driving motor 1 is amplified by the two-stage speed ratio of the gearbox 2 and then input to the mechanical axle. 3 on both sides of the wheel end. The torque input end on one side of the drive motor 1 and the gearbox 2 is connected by flange interface bolts. The torque input and end of the gearbox 2 is co...

Abstract

The invention is a suspension type single-motor electric axle assembly, belongs to the technical field of automobile manufacturing and mainly solves the problems that the transmission chain of the existing pure electric vehicle is longer and part of the space of the vehicle is occupied due to adopting of the power unit structure of the traditional internal combustion engine vehicle. The suspensiontype single-motor electric axle assembly is characterized by comprising a mechanical axle, a driving motor and a gearbox; the driving motor is connected with the torque input end of the gearbox, andthe torque output end of the gearbox is connected with the mechanical axle to form the electric axle assembly; and the mechanical axle, the driving motor and the gearbox are arranged in parallel structures. The suspension type single-motor electric axle assembly has the characteristics of stable power output, high efficiency, compact structure, reducing the weight, increasing the passenger space and battery arrangement space in a carriage, improving the product applicability and competitiveness, and is mainly used for the electric vehicle axle power assembly of the pure electric vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile manufacturing, and in particular relates to an electric axle power assembly for a pure electric vehicle. Background technique [0002] At present, the vast majority of pure electric vehicles adopt the power unit structure of traditional internal combustion engine vehicles, that is, motor, transmission shaft, reducer / differential assembly. Due to the long transmission chain, the loss of transmission efficiency is large, and the parts are large in size, which will occupy part of the space of the car, affect the passenger capacity of the car and the battery layout space, and affect the driving range of the vehicle. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the purpose of the present invention is to provide a drive motor, gear box and traditional mechanical axle integrated into an electric axle assembly, such a compact structural arrangement can sh...
