The brake master cylinder is the main matching part of the hydraulic brake. There is a tank for storing brake oil on the top and a piston in the cylinder below. The piston is acted by the brake pedal in the cylinder and then through the push rod, and transmits the brake hydraulic pressure in the cylinder to each wheel sub-cylinder. It is also a hydraulic brake device and is a brake cylinder arranged in each wheel.
Working principle: When the driver depresses the foot pedal, by pulling the lever, one end of the lever arm presses the balance spring to move the balance arm downward. First, the exhaust valve is closed, and the intake valve is opened. The intake valve is charged into the brake air chamber, and the air chamber diaphragm is pushed to rotate the brake cam to achieve wheel braking, thereby achieving the braking effect
Composition: The main matching part of the hydraulic brake master cylinder. There is a tank for storing brake oil on the top, and a piston in the cylinder below.
Working principle: When the driver depresses the foot pedal, the force of the foot will cause the piston in the brake master cylinder to push the brake fluid forward and generate pressure in the oil circuit. The pressure is transmitted to the brake cylinder piston of each wheel via the brake oil, and the piston of the brake cylinder pushes the brake pads outward, causing friction between the brake pads and the inner surface of the brake drum, and generating sufficient friction to reduce the speed of the wheels. In order to achieve the purpose of braking.
The brake master cylinder is the main control device in the vehicle's service brake system. It realizes sensitive follow-up control during the braking process and release process of the dual-circuit main brake system.
