The braking system of auto brake hose is closely related to safety. A considerable part of traffic accidents are caused by failures of the braking system. It is necessary to check and replace the braking system regularly, instead of waiting for a failure before thinking of replacing it. That would be too late.
The braking system of a car includes a service brake system and a parking brake system. The service brake system is mainly used to reduce the speed and brake during driving, while the parking brake system is to keep the car in a stable state. In case of rolling, it can also work with the service brake system and the parking brake system to brake during emergency braking. The parking brake system generally uses a parking brake lever and a wire cable to implement a parking brake on the rear wheels. The same set of brakes are used as the service brake, and a ratchet device is used for locking.
Service brake system
The service brake system is also what we often call the brake system, which generally uses a hydraulic booster system, consisting of a brake pedal, brake fluid, brake master cylinder, brake hose, brake cylinder, and brakes (disc brakes and drum brakes). ) And other components. During braking, stepping on the brake pedal will drive the brake master cylinder to transfer the brake fluid to the brake cylinder, which then acts on the brake pads/brake discs or drum brakes, forcing the wheel speed to decrease to achieve the braking effect.
Brake master cylinder
The brake master cylinder is also called the brake master cylinder, and its main function is to push the brake fluid to be transmitted to the various brake cylinders to push the pistons. The current brake master cylinder is a tandem dual-chamber brake master cylinder. It can realize dual-circuit hydraulic control. That is to say, the two pistons in tandem are resistant to the same cylinder body. Through the control of the brake pedal, the brake fluid is delivered to the front and rear wheels to achieve a braking effect.
The brake sub-cylinders also have different appearances in different forms of brake systems, but they are the same in essence. They introduce brake fluid, and then push the piston in the sub-cylinder to push the brake shoe or the brake shoe into contact with the brake drum or brake disc. The sub-cylinder of the drum brake system is located in the brake drum, mostly in the form of a plunger, connected to the brake shoe. The sub-cylinder of the disc brake system is actually the brake caliper. It uses the volume change of the brake fluid in the cylinder to push the piston against the brake pad to contact the brake disc by injecting brake fluid into the cylinder. Braking effect.
Brake fluid is a liquid medium that transmits brake pressure in the hydraulic brake system of an automobile, and is used in vehicles that use a hydraulic brake system. Brake fluid is also called brake fluid or force fluid. Its English name is BrakeFluid. It is an indispensable part of the brake system. In the brake system, it is used as a force transmission medium, because the liquid cannot It is compressed, so the pressure output from the master cylinder will be directly transmitted to the sub-cylinder through the brake fluid.
