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.

    本发明公开了一种车辆刹车失效紧急保护系统,属于汽车制动领域,通过在现有的刹车卡钳的基础上创造性的加入紧急制动器来为汽车制动系统添加第三道保护,一定程度上避免了刹车失效带来的伤害,紧急制动器通过监测活塞的位移来判断刹车是否失效,并以此触发点火器来将火药引燃,利用火药燃烧时的高温使叠氮化钠块分解出氮气,大量的氮气进入到刹车卡钳的油道中,利用气体压力挤压刹车油,从而让活塞移动使刹车片与刹车盘摩擦,在刹车总泵或分泵和刹车油及其管路失效时可起到紧急制动的作用,有效保护了乘客的安全,另外当车辆发生碰撞后也可触发紧急制动器来对车辆进行制动,避免二次伤害。
