What are the classifications of braking systems? What are the types of automotive braking systems?

The braking system is generally composed of two main parts: the brake control mechanism and the brake. The brake control mechanism produces the braking action, controls the braking effect, and transmits the braking energy to the various parts of the braking system, and the brake is the part that generates the force that hinders the movement or movement trend of the vehicle.

1.The brake pedal of the car is under the steering wheel, and when the brake pedal is pressed, the brake lever is pressurized and transmitted to the brake pad on the brake drum to jam the brake wheel, so that the car slows down or stops running. The manual brake of the car is next to the gear shift and is connected to the brake bar.

Bicycle brakes are also common, which are decelerated by rod brakes fixed to the frame or disc brakes.

2.The brakes are accomplished by the intense friction between the brake pads and the brake drums.

3.The principle of braking is to convert the kinetic energy of the car into heat energy and consume it, and the kinetic energy comes from the power provided by the engine, which needs to be provided by the work of fuel combustion, which means that if you step on the brakes once, it means that your gasoline will be wasted. So, please remember the first point:

When driving, apply the brakes as little as possible, and braking is only for comfort or in an emergency.

4.Many brakes are emergency brakes as a last resort, so you must pay attention to the braking skills. There are two situations discussed here, one is the vehicle without the ABS anti-lock braking system, and the old vehicles are basically like this.

When this kind of vehicle encounters emergency braking, if the braking force is too large, it may make the car tires lock (the tires do not rotate at all), we can often see two black brake marks that drag a long time on the road, which is the traces of friction between the tires and the ground when the car brakes without ABS, the tires will no longer rotate after the tires are locked due to emergency braking, but the huge inertia will make the tires of the car rub against the ground and continue to slide forward, The violent friction between the tire and the ground caused a black mark on the rubber particles that had been rubbed off on the tire. At this time, if you force the direction, it will often have serious consequences such as deviation, side slippage, tail flicking, or even rollover out of control.

Mechanical, hydraulic, pneumatic and gas-liquid complex.

According to the different functions of the braking system, the braking system can be divided into service brake system, parking brake system, emergency braking system and auxiliary braking system.

The braking system used to slow down a moving vehicle or even stop is calledService brake system

A braking system that keeps a stopped vehicle in place is calledParking brake system

In the event of the failure of the service brake system, the braking system that ensures that the vehicle can still achieve deceleration or stop is calledEmergency braking system

In the process of driving, the braking system that can reduce the speed of the vehicle or keep the speed of the vehicle stable, but cannot be called the emergency stop of the vehicleSecondary braking system

Among the braking systems mentioned above, the service brake system and the parking brake system are required for every vehicle.

How it works. The general principle of operation of the braking system is to prevent the rotation or tendency of the wheels by using the friction between the non-rotating elements connected to the body (or frame) and the rotating elements connected to the wheels (or propeller shafts).

A metal brake drum with an inner circle as the working surface is fixed to the wheel hub and rotates with the wheel. On the immobile brake plate, there are two support pins that support the lower ends of the two curved brake shoes. The outer surface of the brake shoe is equipped with a friction plate.

The brake floor is also equipped with a hydraulic brake wheel cylinder, which is connected with the hydraulic brake master cylinder installed on the frame with an oil pipe. The pistons in the master cylinder can be operated by the driver via a brake pedal mechanism.

When the driver steps on the brake pedal to compress the brake fluid, the wheel cylinder piston presses the brake shoe against the brake drum under the action of hydraulic pressure, so that the brake drum reduces the rotation speed or remains still.

Hydraulic brakes, pneumatic brakes, disc brakes, drum brakes,

There are two main types of this: mechanical type and power assist type.

The composition of the braking system, as a braking system, is of course to make the moving car slow down or even stop according to our wishes. The working principle is to convert the kinetic energy of the car into heat energy through friction. The automobile braking system is mainly composed of energy supply devices, control devices, transmission devices and brakes, and the common brakes mainly include drum brakes and disc brakes.

Drum brakes drum brakes mainly include brake wheel cylinders, brake shoes, brake drums, friction pads, return springs and other parts. Mainly through the hydraulic device is the friction plate and the inner side of the brake drum rotated by the wheel, so as to have the effect of braking. When the brake pedal is pressed, the piston movement of the brake master cylinder is promoted, and then pressure is generated in the oil circuit, and the brake fluid transmits the pressure to the brake cylinder of the wheel to push the piston, and the piston pushes the brake shoe to move outward, so that the friction pad and the brake drum rub.

Friction Friction brakes. Braking is based on the friction between the brake parts and the moving parts.

Non-friction brakes. The structural forms of brakes mainly include magnetic particle brakes (braking by using the shear force generated by magnetic particle magnetization), magnetic eddy current brakes (adjusting the size of braking torque by adjusting the excitation current) and water eddy current brakes.

Brake structure.

It can also be divided into external block brakes, inner shoe brakes, belt brakes, disc brakes, etc.;

Brake parts working condition.

It can also be divided into normally closed brakes (often in the state of tight brakes, which can be released by applying external force) and normally open brakes (often in the state of loose brakes, and external force needs to be applied to brake);

Manipulation methods. It can also be divided into human, hydraulic, pneumatic and electromagnetic force operated brakes.

The role of the braking system.

The braking system can be divided into service brake system, parking brake system, emergency braking system and auxiliary braking system. Among the braking systems mentioned above, the service brake system and the parking brake system are required for every car.

Brake manipulation energy.

The braking system can be divided into human braking system, power braking system and servo braking system. The braking system that uses the driver's body as the only braking energy source is called the human braking system; A system that brakes entirely on the potential energy in the form of air pressure or hydraulics converted from the power of the engine is called a power braking system; A braking system that uses both human and engine power for braking is called a servo braking system or a booster braking system.

Braking energy transmission mode.

The braking system can be divided into mechanical, hydraulic, pneumatic, electromagnetic and other types. At the same time, two types of braking systems are used in the form of energy transmission, which is called a combined braking system.

The classification of braking system is as follows: 1. According to the classification of the role of the braking system, the braking system used to reduce the speed or even stop the moving car is called the driving braking system; The braking system used to keep the stopped car in place is called the parking brake system; In the case of the failure of the service brake system, the braking system that ensures that the car can still decelerate or stop is called the emergency braking system; In the process of driving, the auxiliary service braking system reduces the speed of the vehicle or keeps the speed of the vehicle stable, but it is not known that the braking system that can stop the vehicle in an emergency manner is called the auxiliary braking system;

2. According to the classification of braking control energy, it can be divided into human braking system, power braking system and servo braking system. The braking system that uses the driver's body as the only braking energy source is called the human braking system; A system that brakes entirely on the potential energy in the form of air pressure or hydraulics converted from the power of the engine is called a power braking system; A braking system that uses both human and engine power for braking is called a servo braking system or a booster braking system.

3. According to the transmission mode of braking energy, it can be divided into mechanical, hydraulic, pneumatic, electromagnetic, etc. At the same time, two kinds of braking systems are used in the way of energy transmission, which is called the combined braking system.

The classification of braking systems is as follows:1According to the function of the braking system, the braking system used to slow down or even stop the moving car is called the starting brake system; The braking system used to keep a stopped car in place is called a parking brake system; The braking system that ensures that the car can still slow down or stop in the event that the starting braking system fails, is called an emergency braking system.

In the process of starting, the paving braking system reduces the speed of the vehicle or keeps the speed of the vehicle stable, but the braking system used for the emergency stop of the vehicle cannot be called the paving braking system; 2.According to the classification of braking control energy, it can be divided into hand braking system, power braking system and servo braking system. The braking system with the driver's body as the only braking energy is called the hand brake fluid bindling system; A system that converts the power of the engine into potential energy in the form of air pressure or hydraulics is called a power braking system.

The braking system that uses manpower and engine power for braking at the same time is called servo braking system or auxiliary force braking system; 3.According to the mode of braking energy transmission and slip delivery, it can include mechanical, hydraulic, pneumatic, electromagnetic, etc. At the same time, two braking systems with energy transfer are called combined braking systems.

The braking system can be divided into the following three categories:1According to the classification of the role of the braking system, it can be divided into three types of braking systems:

Launch brake system, parking brake system and emergency braking system. The start brake system is used to slow down or stop a moving vehicle; The parking brake system is used to keep the vehicle in place; The emergency braking system ensures that the vehicle can still slow down or stop if the starting braking system fails. During the start, the paving braking system is used to reduce or stabilize the speed of the vehicle, but it cannot be used for emergency stops.

2.According to the classification of braking control energy, it can be divided into hand braking system, power braking system and servo braking system. The hand brake system relies entirely on the driver's body energy for braking; The power braking system completely relies on the conversion of engine power into potential energy braking in the form of air pressure or hydraulics; The servo braking system is a power assist braking system, which uses both human and engine power for braking.

3.According to the transmission mode of braking energy, it can be divided into mechanical, hydraulic, pneumatic and electromagnetic braking systems. Two braking systems with energy transfer are called combined braking systems.
