Electric vehicle device for deflating rear tire during emergency braking

Abstract

The invention discloses an electric vehicle device for deflating a rear tire during emergency braking. The device comprises a vehicle frame, two rear wheel supporting frames are fixedly arranged at the lower end of the vehicle frame in a front-back symmetrical mode, a rear wheel rotating shaft is arranged between the rear wheel supporting frames in a rotating mode, an installation ring is fixedlyarranged on the rear wheel rotating shaft, and six rear wheel supports are fixedly arranged on the installation ring in an annular array mode. When an electric vehicle runs on a slippery road surfaceor runs at a high speed, the safety of a driver can be guaranteed only by shortening the braking distance during braking action, the device can deflate a rear tire while locking a brake disc, the contact area between the rear tire and the ground is increased, the braking effect is greatly improved, and the braking distance is shortened; in the continuous driving process, the vehicle can automatically inflate the rear tire, and the tire pressure is normal in the driving process.

Description

Technical field[0001]The present invention relates to an electric vehicle apparatus in which the back of the tire is mainly involved in the technical field of vehicle brake devices.Background technique[0002]In daily life, the electric car can be seen everywhere, but when driving on a high-speed or slippery road, it is often easy to cause the tire slip, because when the brake disc is locked, the electric vehicle will still be slippery. Continue to move a certain distance from the direction of travel, the braking action cannot be completed in time, there is a very high safety hazard, you want to solve the above problem, can increase the friction of the tire and the ground by increasing the contact area of ​​the tire and the ground, so the design This device solves the above problems.Inventive content[0003]The technical problem to be solved by the present invention is to provide an electric vehicle device in which the back of the tires in the end of the emergency brake, solves the abov...

AI Technical Summary

Problems solved by technology

[0002] In daily life, electric vehicles can be seen everywhere, but when driving at high speed or on slippery roads, it is often easy to cause the problem of tire slippage when braking, because the electric vehicle will still be in a slippery state when the brake disc is locked. Continue to move a certain distance in the direction of travel, and the braking action cannot be completed in time when braking, which has a very high potential safety hazard. To solve the above problems, the friction between the tire and the ground can be increased by increasing the contact area between the tire and the ground. Therefore, the design This device solves the above problems
