Problems solved by technology

However, there are two defects in this structural design. One is that the braking method is single and there is no backup braking method. When the brake caliper fails, it is very easy to be dangerous; the other is that both the brake caliper and the brake disc are exposed to the outside world. In rainy days or just after passing the car, the friction force between the friction plate and the brake disc will decrease, which will affect the braking effect and pose a safety hazard

Embodiment Construction

[0020] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0021] figure 1 It is a structural schematic diagram of the rear wheel of the electric vehicle described in the present invention, as figure 1 As shown, a rear wheel of an electric vehicle includes a brake disc 1, a left motor case 2, a dust cover 3, and a stator bracket 4, and the brake disc 1, the left motor case 2, a dust cover 3, and a stator The bracket 4 encloses a closed space 5, the closed space 5 is an annular structure, and the brake disc 1 is an annular structure.

[0022] The right side of described left motor housing 2 is equipped with motor cover 10, right motor housing 11, and described left motor housing 2, motor cover 10, right motor housing 11 form a semi-enclosed annular space.

[0023] A main shaft 17 runs through the inside of the stator bracket 4, and the main shaft 17 is connected with a rim 18 through a bearing.

[0024] A steering knuck...

Abstract

A rear wheel of an electric vehicle comprises a brake disc, a left motor casing, a dust cover and a stator support. The rear wheel of the electric vehicle is characterized in that the brake disc, the left motor casing, the dust cover and the stator support define a confined space which is of an annular structure; the brake disc is of an annular structure; a brake wedge is arranged on the inner side of the annular structure of the brake disc; the stator support is of a tubular structure; friction wedges are arranged on the outer side of the stator support; the brake wedge and the friction wedges are positioned in the confined space. The rear wheel of the electric vehicle has the beneficial effects that a driver can apply the brake with either brake component so as to prevent danger. The phenomenon of decrease of friction force due to entering of water is avoided, so that the safety coefficient is increased.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to a rear wheel of an electric vehicle. Background technique [0002] Electric vehicle braking is generally accomplished by friction between the friction plate on the brake caliper and the brake disc. However, there are two defects in this structural design. One is that the braking method is single and there is no backup braking method. When the brake caliper fails, it is very easy to cause danger; the other is that both the brake caliper and the brake disc are exposed to the outside world. In rainy days or just after passing the car, the friction force between the friction plate and the brake disc will decrease, which will affect the braking effect and pose a safety hazard. Contents of the invention [0003] The purpose of the present invention is to design a kind of electric vehicle rear wheel in order to solve the above problems. The specific design scheme is: [0004] A rea...
