What is the function of a brake valve What is a brake

1) Including: air compressor, air reservoir, pressure regulator.

Safety valves, intake air filters, exhaust air filters, pipe filters, oil-water separators.

Air dryers, antifreezes, multi-circuit pressure protection valves and other devices.

2) Function: 1) Air compressor: Manufacture of compressed gas for braking.

2) Air reservoir: used to store compressed air to ensure braking at any time.

3) Pressure regulator and safety valve: ensure that the pressure in the gas reservoir is within the specified range, not only to ensure normal braking, but also to prevent the cylinder from being bursting.

4) Air intake filter, exhaust filter and duct filter: to clean the air and avoid dust, impurities, etc. from entering the braking system.

Reduces wear and improves the service life of braking system components.

5) Oil-water separator: used to separate the moisture and lubricating oil in the compressed air, so as not to corrode the non-oil-resistant rubber parts in the air reservoir and pipeline.

6) Air dryer: The air output by the oil-water separator inevitably contains a small amount of water, and it is dried with a dryer to avoid corroding the air reservoir and other metal devices in the pipeline.

7) Antifreeze: Prevent the residual moisture accumulated in the pipeline and other air pressure elements from freezing and blocking the pipeline in the cold season to ensure normal braking.

8) Multi-circuit pressure protection valve: In the multi-circuit braking system, when a set of circuits is damaged and leaks, the multi-circuit pressure protection valve can ensure that the rest of the intact circuits continue to be inflated.

3) These components are essential for a normal pneumatic braking system.

Function: The brake valve is the main control device in the automobile service brake system, which realizes sensitive follow-up control in the braking process and release process of the dual-circuit main braking system.

Composition: The brake valve is mainly composed of an upper chamber piston, a lower chamber piston, a push rod, a roller, a balance spring, a return spring (upper and lower chambers), an upper chamber valve, a lower chamber valve, an air inlet, an air outlet, an exhaust port, and a ventilation hole.

Principle: when the driver steps on the pedal, one end of the pull arm is pressed down by stretching the pull rod to press the balance spring, so that the balance arm moves down, the exhaust valve is closed first, the intake valve is opened, and the compressed air of the air reservoir is filled into the brake chamber through the intake valve, and the air chamber diaphragm is pushed to make the brake cam rotate so as to realize wheel braking.

The brake valve is an important control device in the pneumatic driving braking system, which can ensure that the driver has a good enough pedal feeling, accurately control the timing of the brake valve to the brake chamber and the timing of pressure and exhaust, and some cars can be used as a control signal to input another control device - relay valve, and ensure that the air pressure in the brake chamber changes proportionally to the stroke of the brake pedal, and the change of output pressure is accurate enough within a certain range, which is gradual and changeable.

A brake is a device that has the function of slowing down a moving part (or moving machinery), stopping, or keeping it in a stopped state. It is a mechanical part that stops or slows down a moving part in a machine. It is commonly known as brake and brake.

This teacher should tell you, the brake should be the brake, the parking brake should be the handbrake, the clutch is not needed to step on the left foot, of course, only the manual transmission has a clutch.

Simply put, it's the brakes.

The brake valve is the main control device of the automobile service brake system. The brake valve is mainly composed of an upper chamber piston, a lower chamber piston, a push rod, a roller, a hairspring, a return spring (upper chamber and lower chamber), an upper chamber valve, a lower chamber valve, an air inlet, an air outlet, an air outlet and an exhaust port. A car with a state bend fitted with an exhaust brake valve has the following advantages:

1.When the car goes down a long slope, it can significantly reduce the number and time of driving braking, which can prevent the brake from overheating and the braking force from decreasing, so that the track making shouter is always in good condition. Extend the service life of shoes, reduce the fatigue of the driver when braking, and contribute to environmental protection; 2.

Exhaust braking is braking created by compressing the gas in the engine and exhaust pipe. Therefore, soft braking, no impact, reducing the impact load of parts, can prolong the service life of related parts, reduce the number of maintenance; 3.The exhaust brake is transmitted to the drive wheels through the drivetrain.

The differential of the drive axle distributes braking torque evenly between the left and right wheels. Reduce the tendency of the car side to be dull and slippery, have a sense of safety when driving, and improve the average speed of the car; 4.The oil barrier switch of the exhaust brake has a certain fuel-saving effect.

The brake valve is the main control device in the service brake system of the car. The brake valve is mainly composed of an upper chamber piston, a lower chamber piston, a push rod, a roller, a balance spring, a return spring (upper and lower chamber), an upper chamber valve, a lower chamber valve, an air inlet, an air outlet, an exhaust port, and a vent. Cars are equipped with exhaust brake valves that have the following advantages:

1. When the car goes down a long slope, the number and duration of the driving brake can be significantly reduced, so as to prevent the brake from overheating and the braking force from declining, and keep the brake in good condition. It prolongs the life of the shoe, reduces the fatigue of the driver's braking process, and is conducive to environmental protection;

2. Exhaust brake is the brake produced by compressing the gas in the engine and exhaust pipe. Therefore, Zhaopei brakes softly, without impact, reduces the impact load of parts, can prolong the service life of related parts, and reduce the number of maintenance;

3. The exhaust brake is transmitted to the side wheel of the drive through the drive train. The differential on the axle distributes the braking torque evenly to the left and right wheels. It reduces the tendency of the car to guess the rubber on the side of the sliding limb, and has a sense of safety when driving, which can increase the average speed of the car;

4. The oil stop switch of the exhaust brake has a certain fuel-saving effect.

Millions of car purchase subsidies.

1. Emergency braking: emergency braking is emergency braking, in the process of driving the car, the driver uses the brake correctly and quickly, so that the vehicle can stop the car in the shortest distance;

2. To put it simply, it is emergency braking, but emergency braking is not just a foot to press the brake to the end, the correct emergency braking method is also very important, and not under all circumstances can use emergency braking;

3. The so-called emergency braking is naturally used in an emergency, because emergency braking will cause relatively large damage to the car and tires, and the vehicle under emergency braking is more difficult to control, and it is not suitable for frequent use.

The brakes play the role of slowing down and stopping the car while it is moving. In general, the service brake (foot brake) is a convenient way to slow down and stop while on the road. But if the service brake fails, you can use the parking brake.

Brakes can be divided into the following five types:1Throttle Controlled Braking:

When you need to slow down, keep in third gear and completely release the throttle differential fluid. At this time, the engine tends to idle, which creates a resistance to the transmission system, acts on the wheels, and achieves the purpose of deceleration. 2.

Exhaust brake: There is a disc valve at the junction of the exhaust manifold and exhaust pipe of a high-power diesel engine. When the gear is in gear, the solenoid switch is operated to close it, suffocating the engine, so as to achieve the braking effect.

As soon as the accelerator is pressed, the valve will be automatically opened. 3.Hydraulic Turbine Reducer:

Add a turbine chamber at the rear end of the gearbox. When the brake circuit is switched on, the transmission oil creates damping in the turbine to achieve the braking effect. Although there is no wear and tear, heat dissipation increases.

4.Electric turbine virtual reducer: It is equivalent to installing a "generator" on the transmission shaft.

When not energized, there is no contact and wear. When braking is required, the circuit is turned on, and the transmission shaft is resisted by the rotten rock of the electromagnetic field to achieve the purpose of braking. 5.

Engine braking structure: The brake signal makes the exhaust valve slightly open and not closed, and the piston moves up and down to generate braking force due to the air flow resistance.

Hello, dear. The function of the valve core of the brake digging stove valve: the valve core is the valve part of the valve body with the help of its movement to achieve the basic function of direction control, pressure control or flow control.

The working principle of the brake valve and the valve core: when the driver steps on the pedal, one end of the pull arm is pressed down by stretching the pull rod to judge the balance spring, so that the balance arm moves down, the exhaust valve is closed at first, and the intake valve is opened, and the compressed air of the air reservoir is filled into the brake chamber through the intake valve, and the diaphragm of the air chamber is pushed to rotate the brake cam to realize wheel braking. Brake valve and spool function:

The brake valve is the main control device in the automobile service brake system, which realizes sensitive follow-up control in the braking process and release process of the dual-circuit main braking system.
