Gas-automotive brake fluid and brake oil brake. Brake gas
1, the gas is air tight brake unit (commonly known as an air pump), a minimum of two air reservoir, a brake master cylinder, a front wheel quick release valve, the rear relay valve a. four brake cylinder, adjust the back four, four cams, brake shoes and brake eight ancient four components. Brake oil liquid
2, the brake master cylinder by a brake oil (brake hydraulic pump) and the brake fluid reservoir composition.
using a truck air brakes, brake oil are generally car, so the car brake master cylinder and wheel cylinders are hydraulic brake pump. Brake cylinder (hydraulic brake pump) are indispensable parts brake system, when braking the brakes when you plate, put the brake master cylinder to the brake fluid pressure in each brake wheel cylinder through the feed pipe. The brake cylinder has a link control brake shoes or brake pads. When the brake, the brake oil in the brake pipe to the brake cylinder push rod on the brake shoe intensify flanged wheels on the wheel stop. The technical requirements of automotive brake wheel cylinder high, because he directly affect people’s lives.
2. Use
brake wheel cylinder brake system is an indispensable part, its main action is a top movable brake pads, drum brake friction brakes. And still reduce the vehicle speed.
3, Principle
car
After depressing the brake master cylinder hydraulic thrust cylinder overwhelm oil, a piston inside the cylinder by the brake hydraulic pressure begins to move to promote the film. Oil from the brake master cylinder and the brake is a brake oil tank composed. They attached a brake pedal, a brake hoses attached. Brake master cylinder with a brake fluid within the reservoir, and has an oil inlet and the oil outlet. When the brakes, the oil outlet openingOil feed port is closed. At a pressure piston pump, brake hoses are extruded tubing flow to each brake cylinder for braking function. When the brake pedal is released. Brake master cylinder inside the oil outlet will close, oil inlet open, the brake fluid flowing from each brake wheel cylinder into the brake master cylinder, back to the original state. Trucks
by a pump driven by the engine, the air compression to the high pressure gas stored in the gas cylinder. One of the energy accumulator to the brake master cylinder through the associated conduit. Brake master cylinder the upper and lower air chambers, on the rear air chamber control, under the control of the front air chamber. when the driver presses the brake pedal, the gas is first opened, the high pressure gas accumulator pass to the relay valve. Release the control piston of the relay valve, this time Further a gas accumulator can live relay valve and two rear wheel cylinders is turned on. Release brake cylinder push rod forward, back through the toner angular rotation of the cam, the cam is eccentric, while rotating the brake shoes Old distraction brake friction generating arrival braking effect, while
on the brake master cylinder chamber open lower chamber also open, high-pressure gas into the quick release valve, and then distributed to the two front wheel cylinders after the same.
when the driver releases the brake pedal, the upper and lower gas chamber closed front wheel and the rear wheel fast into the valve piston of the relay valve action of the spring in position next time. plenum front and rear brake cylinder with the atmosphere linked, the return push rod, the end of the brake.
generally First wheel brake, the front wheel later, so that the driver controls the direction of benefit.
