with the main part of the brake master cylinder braking oil pressure, battery saving groove brake fluid thereon, the bottom is equipped with a piston within the cylinder. The piston in the cylinder is then subject to a brake pedal acting through the push rod, the hydraulic cylinder is transmitted to the respective wheel brake cylinders points, the hydraulic brake device is disposed in the brake cylinder of each wheel.
1. The brake master cylinder noun
with the main part of the brake master cylinder braking oil pressure, battery saving groove brake fluid thereon, the bottom is equipped with a piston within the cylinder . The piston in the cylinder is then subject to a brake pedal acting through the push rod, the hydraulic cylinder is transmitted to the respective wheel brake cylinders points, the hydraulic brake device is disposed in the brake cylinder of each wheel.
2. Classification of brake master cylinder
The pneumatic brake master cylinder into a hydraulic brake master cylinder and the brake master cylinder into two categories.
● pneumatic brake master cylinder
: the pressure of the brake master cylinder main piston chamber, the lower chamber of the piston, the push rod, roller, spring balance, back spring (upper and lower chambers), the valve chamber, the valve chamber, air inlet, outlet, exhaust outlet, the composition of the vent hole.
Working principle: When the driver depresses the foot pedal, by stretching the pull rod end of the arm under the pressure balance spring, so that the balance arm down, the exhaust valve is first closed, open the inlet valve, at this time the compressed air accumulator is charged intake brake chamber, the air chamber diaphragm push the brake in order to achieve rotation of the cam wheel, so as to achieve the braking effect
● hydraulic brake master cylinder
composition: main fitting part of a hydraulic brake master cylinder with brake fluid tank pool deposits thereon, the bottom is equipped with a piston within the cylinder.
Working principle: When the driver depresses the foot pedal, the piston in the brake oil to push forward biased to cause the foot brake master cylinder and a pressure in the oil passage. Pressure is transmitted via the brake fluid to the wheel brake cylinder of each piston, the piston brake wheel cylinder brake pad and then push outwards, the inner surface of the brake pads and the brake drum friction and generate sufficient friction to reduce the rotational speed of the wheel, in order to achieve the purpose of the brakes.
3. The action of the brake master cylinder
automotive brake master cylinder is one of the main driving system of the braking control apparatus, servo control sensitive to achieve the dual-circuit braking system and the master brake release process.
Working principle: When the driver depresses the foot pedal, by stretching the pull rod end of the arm under the pressure balance spring, so that the balance arm down, the exhaust valve is first closed, open the inlet valve, at this time the compressed air accumulator is charged intake brake chamber, the air chamber diaphragm push the brake in order to achieve rotation of the cam wheel, so as to achieve the braking effect.
