Brief Introduction of Automobile Braking System

The only thing that can brake the car is the external force acting on the car and the direction is opposite to the driving direction of the car, and the magnitude of these external forces are random and uncontrollable, so a series of special devices must be installed on the car to achieve the above functions

The car braking system refers to the special braking mechanism installed on the car in order to technically ensure the safe driving of the car and improve the average speed of the car. Generally speaking, the automobile braking system includes two independent devices, the service braking device and the parking braking device. Among them, the service brake device is operated by the driver's foot, so it is also called the foot brake device. The parking brake is operated by the driver's hand, so it is also called the hand brake.

The function of the service brake device is to slow down or stop the vehicle in the shortest distance. The function of the parking brake is to keep the car stationary on various roads. However, sometimes in emergency situations, the two braking devices can be used at the same time to increase the braking effect of the car. For some special-purpose cars and cars that often travel in mountainous areas, long-term and frequent braking will cause the service brake device to overheat, so various types of auxiliary braking devices are often added to these cars to stabilize when going downhill. speed.

According to the braking energy, the braking system can also be divided into three types: human braking system, dynamic braking system, and servo braking system. The human braking system uses the driver's physical strength as the braking energy; the dynamic braking system uses the air pressure or hydraulic pressure converted from the engine power as the braking energy; and the servo braking system uses both human and engine power as the braking energy. In addition, according to the transmission method of braking energy, the braking system can be divided into mechanical, hydraulic, pneumatic and electromagnetic.

In the category of automotive braking systems, a brake is a component in an automotive braking system that is used to generate a force that resists the movement or tendency of a vehicle to move. Currently, the brakes used in all types of cars are friction brakes, that is, the braking torque that prevents the movement of the car is derived from the friction between the stationary element and the rotating working surface.
