Anti-collision rear axle of electric vehicle

Abstract

The invention discloses an anti-collision rear axle of an electric vehicle. The anti-collision rear axle of the electric vehicle comprises an electric vehicle rear axle rod body, an anti-collision plate and a plurality of connecting pieces, the plurality of connecting pieces are used for connecting the electric vehicle rear axle rod body and the anti-collision plate. By arranging the anti-collision plate, the electric vehicle rear axle rod body can be effectively protected, and the electric vehicle rear axle rod body is prevented from deforming when the electric vehicle rear axle rod body is accidentally collided in the driving process; a damping spring is arranged between the anti-collision plate and a vehicle body, so that the impact energy can be effectively absorbed, and compared withan existing rigid-connected anti-collision device, the protection effect of the anti-collision rear axle of the electric vehicle is better; the anti-collision plate is provided with an inclined plate,so that muddy water can be effectively prevented from intruding into parts on the electric vehicle rear axle rod body, and a differential mechanism and a driving motor on the electric vehicle rear axle rod body are effectively protected.

Description

technical field [0001] The invention relates to an anti-collision rear axle of an electric vehicle, which belongs to the technical field of electric vehicle rear axles. Background technique [0002] The rear axle refers to the rear drive shaft component of the vehicle power transmission. It consists of two half-bridges that implement half-bridge differential motion. The rear axle of an electric vehicle includes a propeller shaft, a differential and a drive motor. Domestic current electric tricycle is an indispensable means of transportation in people's daily life, and has the advantages of safe use and low cost. However, when using electric tricycles in the countryside, because the road quality is relatively poor, it is easy for ground protrusions to hit the rear axle of the electric vehicle, resulting in deformation of the rear axle of the electric vehicle and damage to the motor. Contents of the invention [0003] In view of the problems existing in the above-mentione...
