Vehicle brake failure emergency protection system

Abstract

The invention discloses a vehicle brake failure emergency protection system, which belongs to the field of vehicle braking, and is characterized in that an emergency brake is creatively added on the basis of existing brake calipers to add third protection for a vehicle brake system, so that damage caused by brake failure is avoided to a certain extent. The emergency brake judges whether brake fails by monitoring displacement of a piston, triggers an igniter to ignite gunpowder, decomposes sodium azide blocks into nitrogen by means of high temperature during gunpowder combustion, a large amount of nitrogen enters an oil duct of brake calipers, and brake oil is extruded by means of gas pressure. Therefore the piston moves so that friction between a brake plate and a brake disc is caused. When a brake master cylinder or a brake slave cylinder, brake oil and a pipeline of the brake oil fail, the emergency braking function can be achieved, the safety of passengers is effectively protected, in addition, when a vehicle is collided, an emergency brake can be triggered to brake the vehicle, and secondary damage is avoided.

Description

technical field [0001] The invention relates to the field of automobile brakes, and more specifically relates to a vehicle brake failure emergency protection system. Background technique [0002] Automobile braking system refers to a special braking mechanism that installs braking devices on automobiles in order to technically ensure the safe driving of automobiles and increase the average speed of automobiles. Generally speaking, the automobile brake system includes two independent devices of the service brake device and the parking brake device. The driving brake device is operated by the driver with his feet, so it is also called the foot brake device. The parking brake device is manually operated by the driver, so it is also called the hand brake device. The function of the service brake device is to slow down the moving car or stop it in the shortest distance. The function of the parking brake device is to keep the car that has been parked on various road surfaces st...

Problems solved by technology

[0003] The importance of brakes is known even if it is not repeated here. Although brakes are only a part of the vehicle, once the brakes fail, the consequences are unimaginable

There are many reasons for brake failure, mainly one: lack of necessary maintenance for the brake system, too many impurities in the brake master cylinder, poor sealing, failure of the vacuum booster pump, dirty brake fluid or mixed use of several brake fluids Air resistance, oil leakage from the brake master cylinder or sub-cylinder, air leakage from the gas storage tank or pipeline; 2: Failure of the machine due to improper operation, such as long-term downhill, which will cause friction and heat generation of the brake pads and carbonization of the brake hub 1. The brake function is completely invalid; 3. Due to severe overload, under the action of gravity acceleration, Jiada has lost the inertia of the vehicle, which directly leads to brake failure

[0004] Brake devices are mainly divided into two types: butterfly (disc) and drum. For butterfly brakes, no matter what causes the brakes to fail, it will eventually cause the pistons in the brake calipers to fail to drive the brake pads forward. Vehicles with butterfly brakes have two kinds of emergency braking devices, hand brake and engine brake, but for novice and inexperienced female drivers, hand brake and engine brake cannot solve the problem of brake failure in time
