What is the function of a hand brake? What is the role of the brakes

Hand brake is a braking device that makes the car not slippery when parked, and in special cases, it is used in the era of emergency braking or foot failure with foot movement.

The function of the hand brake is to prevent the wheels from turning when the vehicle is parked or when going up and down hills.

When the wheels are turning rapidly, the hand brake cannot be used.

Parking state auxiliary braking.

The function of the braking system is: to make the moving car force to slow down or even stop according to the driver's requirements; Stable parking of stopped cars in various road conditions, including on ramps; Keep the speed of the car going downhill steady.

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

Automobile braking system refers to the installation of a special braking mechanism with braking devices 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 sets of service brake device and parking brake device. Among them, the service brake device is operated by the driver with his feet, so it is also called the foot brake device.

The parking brake device is operated by the driver by hand, so it is also called the hand brake device.

To reliably hold the vehicle in a parked position without skidding, the brakes are generally applied after parking and released before starting.

How it works] 1Disc brakes.

Disc parking brake Disc brake, also known as disc brake calling, is named after its shape as the name suggests. It is controlled by hydraulic pressure, and the main components are brake discs, cylinders, brake calipers, oil pipes, etc. The brake disc is bolted to the axle head of the wheel with alloy steel bolts and rotates with the wheel.

The sub-cylinder is fixed on the bottom plate of the brake. The two friction pads on the caliper are mounted on each side of the brake disc. The piston of the sub-cylinder is driven by the hydraulic action from the oil pipe, and the friction plate is pressed against the brake disc to cause friction braking, and the action is as if the rotating disc is clamped with pliers to force it to stop.

This kind of brake dissipates heat quickly, is light in weight, simple in structure, and easy to adjust.

2.Drum brakes.

Drum Parking Brake Principle A typical drum brake is mainly composed of a base plate, a brake drum, a brake shoe, a brake cylinder (brake cylinder), a return spring, a fixing pin and other parts. The bottom plate is installed in the fixed position of the axle, it is fixed, and it is equipped with brake shoes, oil cylinders, return pins and leakage springs, and fixed pins to withstand the rotational torque during braking. Each drum has a pair of brake shoes, and the brake shoes have friction linings.

The brake drum is mounted on the wheel hub and rotates with the wheel, and it is made of a certain amount of cast iron, which is shaped like a garden drum. When braking, the cylinder piston pushes the brake shoe to compress the brake drum, and the brake drum is decelerated by friction, forcing the vehicle to stop rotating.

Hand brake is a device that makes the car not slip when parked, and in special cases, cooperates with the foot brake.

A hand brake, commonly known as a hand brake, is a device that fixes the car body on the ground or on a certain plane without relative movement.

It is used to stabilize the vehicle after the vehicle is parked to avoid accidents caused by rolling when the vehicle is parked on a slope. The common handbrake is generally placed in the driver's right hand in a down-hanging position for easy use.

When applying the handbrake brake, step down on the letter slag brake pedal and pull the handbrake lever all the way up. To release the handbrake, press down on the brake pedal, pull the handbrake lever up slightly, press the button on the end of the handbrake lever with your thumb, and then lower the noisy handbrake lever to its original position!

The function is to stabilize the vehicle after the vehicle is stopped, to avoid the car to slip when the car is parked on the slope road, to start smoothly on the ramp, and to temporarily use or cooperate with the handcar brake brake for emergency braking after the driving brake effect fails.

Hand brake: a longitudinal device that can fix the body on the ground or on a certain plane without relative movement. 【Function】 Keeping * reliably in the parked position and slipping due to the source posture is not cracked, generally the brake is implemented after parking and the brake is released before the start of the sale.

The function of the hand brake is to prevent the vehicle from rolling when it is unmanned after it has stopped.

Brake old exciter: a longitudinal device that can fix the body on the sock ground or on a certain plane without relative movement.

Function: Maintain the parking position reliably without slipping, generally after the stop is to brake and release the brake before starting.

Brakes, the name tells you.

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.

The function of the brake: 1. In the process of driving, it is convenient to slow down and stop; 2. Keep the car still and prevent the vehicle from sliding forward and backward. The brake is a device that has the function of decelerating, stopping or maintaining the stop state of the moving parts, commonly known as brakes and brakes, which are mainly composed of frames, brakes and control devices.

Automobile brakes are divided into: service brakes (foot brake), parking brakes (hand brake), balance booster brakes, balance booster brakes in the process of driving with spiral groove brake drum will keep the car balanced throughout the driving process, has a good effect on the driver of heavy-duty vehicles.

Brake or Wang is commonly known as brake, which is a device that can make a moving object slow down, stop or even remain stationary. The deceleration brake tools matched on cars, motorcycles, bicycles and other vehicles can be called brakes, and the brakes are mainly composed of operating devices, brake parts, brake frames and other parts. The above is the answer to the question "what is a brake", and the following is some additional content about the brake, interested readers can continue**.

1. Adjustable brakes: Most of the brakes are adjustable, so as to achieve a more comfortable braking strength, and for the brakes used in racing, the adjustable range will be larger.

2. Application of brakes: brakes are not only used in vehicles, but also in all objects that can move, such as common elevators have brakes.

3. Types of brakes: The types of brakes can also be divided into disc brakes, fixed caliper brakes, non-friction brakes and so on according to the different use environments.

4. The temperature of the brake: The brake has a maximum working temperature limit, once the temperature is exceeded, the role of the brake will be weakened or even disappeared.

Summary. Hello oh dear, the brake is a braking device. A brake is a braking device, a mechanical part that stops or slows down moving parts in a machine.

Brake pads are generally composed of steel plates, bonded insulation, and friction blocks, where the insulation layer is composed of materials that do not transfer heat for the purpose of heat insulation. The friction block is composed of friction materials and adhesives, and is squeezed on the brake disc or brake drum to produce friction when braking, so as to achieve the purpose of decelerating and braking the vehicle. <>
