How are braking systems classified, and what can be divided into car braking systems?

Classification of braking systems:

Press 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. The braking system used to make a moving car reduce its speed or even stop is called a service brake 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 the braking system of the emergency stop of the vehicle cannot be called the auxiliary braking system. Among the braking systems mentioned above, the service brake system and the parking brake system are required for every car.

2) Press the brake to manipulate the 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.

3) According to the transmission mode of braking energy.

The braking system can be divided into mechanical, hydraulic, pneumatic, electromagnetic, etc. 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 general working principle of the braking system.

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).

The braking system applied in the automobile can be divided into two types, one is the hydraulic braking system; One is the pneumatic braking system.

The working principle of the hydraulic braking system: in physics, we know that "the pressure in the liquid is equal everywhere", the use of closed pipelines to connect the hydraulic pump, when the pressure of the brake cylinder acts on the brake fluid, the liquid is incompressible, and the pressure is transmitted to the brake cylinder, so that the two pistons in the cylinder are stretched to both sides under the action of liquid pressure, and the brake pads and brake discs are pushed to generate braking force. From this we know that a hydraulic pump is necessary in a hydraulic braking system.

Brake system. Pascal's Law is applied. To put it simply, the pressure applied to the fluid of the brake master cylinder after we press the brake pedal is equal to the liquid pressure at the brake, but because the pressure is equal to the pressure per unit area, the pressure applied will increase as long as the area of the piston is increased. For example, in the experiment below, two cylindrical pistons, the diameter of the left piston is 2 inches, and the diameter of the right piston is 6 inches, which is 3 times that of the left piston, then if a certain amount of force is applied to the left piston.

The braking system of the automobile 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;

The braking system of the car can be divided into: parking brake, service brake, emergency braking, and auxiliary braking.

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.

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 is divided into two types: drum brake and disc brake, and the braking system is composed of four parts: energy supply device, control device, transmission device and brake. The characteristics of disc brakes and drum brakes are as follows: 1. Drum brakes, the cost of drum brakes is cheap, and in line with the traditional design, for heavy vehicles, because the speed is generally not very high, the durability of brake shoes is also higher than that of disc brakes; 2. Disc brake, the heat dissipation performance of the disc brake is very good, and the response of the braking system is relatively fast, and it can do high-frequency braking action.

Compared with drum brakes, disc brakes have a simple structure and are easy to maintain. 3. Drum brake, heat dissipation is much worse, secondly, the braking force stability is insufficient, the braking changes on different road surfaces are very large, not easy to control, and may cause brake recession and brake failure when continuously stepping on the brakes; 4. The cost of the disc brake is relatively expensive, and it is not suitable for some special environments, such as the sand and gravel in the limb forest conditions, which will easily damage the brake disc. In addition, the friction area between the brake pad and the brake disc of the disc brake is smaller than that of the drum brake, and the power of the brake is also smaller, and the wear of the brake pad is larger, and the frequency of replacement is higher.

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.
