Electric vehicle rear axle with protective structure

Abstract

The invention discloses an electric vehicle rear axle with a protective structure. The electric vehicle rear axle comprises a protective pipe, a drive protective shell, a motor, a transmission shaft and rotation wheels. The drive protective shell is fixedly welded to the outer side wall of the protective pipe, an inner cavity of the drive protective shell communicates with an inner cavity of the protective pipe, the transmission shaft is arranged in the inner cavity of the protective pipe and does not make contact with the side wall of the inner cavity of the protective pipe, the two rotationwheels are arranged and fixedly welded to the two ends of the transmission shaft, inward-recessed grooves are formed in the outer walls of the two rotation wheels, protective rings are fixedly bondedto the two sides of the protective pipe, and shelter rings are fixedly bonded to the sides, away from the center of the protective pipe, of the protective rings. By the adoption of the electric vehicle rear axle with the protective structure, through arrangement of first supports, rotary shafts, supporting boards and a protective cover, the protective cover is arranged above the motor and sheltersthe motor, impurities such as dust and water falling from an electric vehicle can be prevented from entering the motor, the motor is protected, and the motor is safer.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle rear axles, and in particular relates to an electric vehicle rear axle with a protective structure. Background technique [0002] The rear axle refers to the rear drive shaft component of the vehicle's power transmission. It consists of two half-bridges that implement half-bridge differential motion. If it is a vehicle driven by the front axle, then the rear axle is just a follower bridge, which only plays the role of carrying. If the front axle is not the drive axle, then the rear axle is the drive axle. At this time, in addition to the bearing function, it also plays the role of driving, deceleration and differential speed. If it is four-wheel drive, there is generally a distribution in front of the rear axle. actuator. [0003] The rear axle is widely used (such as electric vehicles, automobiles, etc.), and it is also a relatively mature mechanical component in the existing technolo...

AI Technical Summary

Problems solved by technology

[0003] The rear axle is widely used (such as electric vehicles, automobiles, etc.), and it is also a relatively mature mechanical component in the existing technology. However, the current rear axle cannot protect the motor, and there is no structure to protect the motor on it, so that the motor is directly exposed. , the fallen debris on the electric vehicle may affect the work of the motor
