A braking system is a series of special devices used in an automobile to impose a certain amount of force on some parts of the automobile (mainly the wheels) by an external force (mainly the road).
The function of the braking system is to make the driving car decelerate or even stop according to the driver's requirements.
Stabilising parked cars under all road conditions, including on ramps;
To keep the speed of a car going downhill.
The braking action on the car can only be acting on the car and the direction of the opposite direction of the car driving, and the magnitude of these external forces are random, uncontrollable, so the car must be equipped with a series of special devices to achieve the above functions.
function
In order to ensure the safety of the car, improve the average speed of the car, to improve transport productivity, in all kinds of cars are equipped with special brake mechanism.
Such a series of specialized devices is known as the brake system.
Automobile brake system function
1) Ensure that the car can slow down and stop as required by the driver
2) Ensure the vehicle reliable parking brake system
type
1.
According to the function: service brake system parking brake system auxiliary brake system
1) Driving brake system -- it is operated by the driver with his foot, so it is also called foot brake system.
Its function is to slow down or stop a moving car for the shortest distance.
2) Parking brake system -- It is manually operated by the driver, so it is also called hand brake system.
Its function is to keep cars that are already parked on all kinds of roads in place
3) Second braking system -- A set of devices to ensure that the car can still decelerate or stop in case of failure of the driving braking system.
In many countries, brake regulations stipulate that a second brake system is also a must for the automobile.
4) Auxiliary braking system -- vehicles that often drive in mountainous areas and some special-purpose vehicles are used to stabilize the speed when going downhill in order to improve the running safety and reduce the deterioration of the performance of the driving braking system and the wear of the brakes.
2.
According to the brake energy transmission: mechanical type, hydraulic type, pneumatic type, electromagnetic type, combined type.
3.
How many points by circuit: single circuit brake system, double circuit brake system.
4.
Divided by energy: human braking system, power braking system, servo braking system.
1) Human braking system -- the braking system that takes the driver's body as the only braking energy.
2) Power brake system -- a brake system that USES the potential energy in the form of air pressure or hydraulic pressure converted from the power of the engine to brake.
3) Servo braking system -- a braking system that USES both manpower and engine power for braking.
According to the role of the braking system classification
Brake system can be divided into service brake system, parking brake system, emergency brake system and auxiliary brake system.
The braking system used to slow down or even stop a moving car is called the driving braking system.
The braking system used to make a stopped car stay in place is called parking brake system.
In the case of failure of the driving braking system, the braking system which ensures that the car can still decelerate or stop is called the emergency braking system.
In the process of driving, the auxiliary driving braking system can reduce the speed or keep the speed stable, but the emergency braking system of the vehicle cannot be called the auxiliary braking system.
Among the above braking systems, the driving braking system and parking braking system are all necessary for every car.
According to brake control energy classification
The braking system can be divided into manpower braking system, power braking system and servo braking system.
The braking system with the driver's body as the only braking energy is called human braking system.
A pneumatic braking system that relies entirely on the power of the engine
Or hydraulic form of potential energy braking system is called dynamic braking system;
The braking system which USES both manpower and engine power for braking is called servo braking system or booster braking system.
According to the braking energy transmission mode classification
Brake system can be divided into mechanical type, hydraulic type, pneumatic type, electromagnetic type.
The braking system that adopts two or more modes of energy transmission at the same time is called combined braking system.
