Structure and working principle of disc brakes (illustrated)

Automotive Principles 2019-12-05 16:42:20


Most vehicles today use disc brakes. When the brake pedal is depressed, the brake pads mounted on the inside and outside of the housing are pressed against the rotating brake disc by hydraulic pressure. The kinetic energy is converted into heat through friction, and the car is braked. Disc brakes are superior to drum brakes in terms of anti-fading performance, sensitivity, and maintenance. Plate ...

Drum brakes are a type of brake used earlier in automobiles, and they are also more commonly used in trucks or passenger cars. Compared with disc brakes, the biggest advantage of drum brakes is that it can generate huge braking force with less force, but its heat and water resistance, self-adjustment of brake clearance, braking ...

Automotive Principles 2019-10-26 21:21:23


The working principle of the automobile air-conditioning refrigeration system is as follows: (1) Compression process: The low-temperature and low-pressure gaseous refrigerant on the low-pressure side of the evaporator is compressed into a high-temperature and high-pressure gaseous refrigerant and sent to the condenser to cool down. (2) Condensation process: the superheated gaseous refrigerant sent to the condenser ...

Automotive Principles 2019-04-22 16:17:34


Drivers' distraction, fatigued driving, and insensitive response to emergencies are important reasons for traffic accidents. According to statistics, about 14% of highway accidents are caused by cars deviating from lanes. If the driver does not concentrate within 3s, 80% will cause lane departure and rear-end collision ...
