Problems solved by technology

The fundamental defects of traditional braking technology are: 1. Spring energy storage braking and retarding braking torque are weak, and only control the rear wheel; The dynamic and main brakes cannot be used together
Therefore, when the main brake fails and fails, the emergency efficiency of the traditional braking technology is poor, and the braking force cannot be given in a timely and reasonable manner, and the speed control and parking within the artificial safety range are lost.
[0004]The consequences of brake failure and bad brakes are often major traffic accidents, which are likely to cause casualties, damage to vehicles and damage to public facilities. personal serious harm or loss

Abstract

The invention discloses an anti-failure brake master valve, comprising an upper valve body, a middle valve body and a lower valve body, wherein the upper valve body provides an impelling force; the middle valve body is of a pneumatic valve structure in a normal condition; and the lower valve body is applied to timely and effectively compensate a brake torque via air release control on an air outlet in case of system fault blockage, component locking, air pressure reduction and rapid leakage, and can repair a front wheel in the case that the front wheel is failed, repair a rear wheel in the case that the rear wheel is failed, and repair a whole automobile in the case that the whole automobile is failed. The anti-failure brake system composed of the anti-failure brake master valve disclosed by the invention and other components is high in safety and reliability, excellent in performance, simple in structure, convenient in installation, strong in practicability, strong in social benefits and economic effects, wide in development prospect, and easy to popularize.

Description

technical field [0001] The invention relates to a brake valve in an automobile brake system, in particular to a failure-preventing brake master valve for automobiles. Background technique [0002] Brake failure and failure can be divided into rear axle, front axle and the whole vehicle - because air brake technology is mainly used in medium and large vehicles, and medium and large vehicles are often prone to various reasons such as poor working conditions and defects in traditional braking technology. Cause brake failure, poor braking. For example, various factors such as: low-temperature system pipelines are blocked by water accumulation, system components are frozen and issued, high and low temperature system pipe fittings and components are damaged and leak air, etc., seriously affect the braking reliability. [0003] According to the basic safety requirements of the traditional air brake technology, the following two auxiliary brakes must be provided in addition to the ...
