Emergency brake system of trailer

Abstract

The invention discloses an emergency brake system of a trailer. The emergency brake system comprises a brake plate arranged below a chassis of the trailer. The brake plate is fixed on the chassis of the trailer through connecting structures. A friction layer is fixed on the lower surface of the brake plate. The width of the brake plate is less than the distance between the inner sides of wheels of the trailer. A control button or handle for controlling the connection structures to move to make the brake plate fall is arranged in a cab of the trailer, and friction is caused between the falling brake plate and the ground under the pressure of an axle to force the vehicle to be braked. According to the emergency brake system of the trailer, under the condition of a brake failure or an emergency brake, a driver can quickly release the brake plate through the control button or handle in the cab, friction is caused between the friction layer and the ground under the pressure of the axle, so that the trailer is quickly braked at a short distance, and the problem that the driver cannot deal with the situation of brake failures presently is solved. The emergency brake system of the trailer has obvious beneficial effects and is suitable for application and popularization.

Description

technical field [0001] The present invention relates to a trailer emergency braking system, and more specifically relates to a trailer emergency braking system which performs friction braking through a brake plate dropped between the vehicle axle and the ground. Background technique [0002] As a kind of cargo transportation vehicle, the trailer has the characteristics of large cargo capacity, long transportation distance and long driving time. Especially when transporting on mountainous roads, if brake failure or emergency occurs, traffic accidents are very likely to occur, causing great harm. loss of life and property. It is not uncommon to see traffic accidents caused by trucks not being able to brake at home and abroad. [0003] Trucks (usually trailers) use stored pressurized gas as the braking power. If the gas pipeline is damaged or other faults occur, the brakes will fail. In the event that braking is required, the driver will be helpless when the brakes fail, and ...

AI Technical Summary

Problems solved by technology

On the continuous downhill section, if the truck brakes continuously, the brakes will easily fail due to the long-term friction between the brake shoe and the brake hub. For the truck with brake failure, the most effective way to avoid traffic accidents is to Allow vehicle to stop, also do not have a kind of effective method or device that can stop the lorry of brake failure at present
