Design of Emergency Braking Device for Heavy Truck Running Brake System Failure

本论文以重型货车气压制动系统为例,在汽车原有的制动装置上设计了汽车行车制动失灵时的应急制动装置,当行车制动装置失灵时,应急制动装置自动起作用,产生应急制动,防止汽车失控,保障人员和车辆的安全。本设计从系统的结构、工作原理等方面进行了论述,以供汽车生产厂家改进汽车制动系统的安全性借鉴。

The thesis takes automatic braking system for heavy truck as an example. It has the design of emergency braking device in case of failure of heavy truck service braking device. When the vehicle brake is out of order, emergency braking device automatically starts so as to generate emergency braking, prevent vehicle out of control and safeguard personnel and vehicle safety. The design is discussed from the aspects of system structure and working principle in order to be used as a reference for automobile manufacturers to improve the safety of automobile braking system.
