The general working principle of the brake system is to prevent the rotation or rotation of the wheel by the mutual friction between the non-rotating element connected to the body (or the frame) and the rotating element connected to the wheel (or the drive shaft). 1) There is a gap between the hoof drum when the brake system is not working, the wheel and the brake drum can rotate freely. 2) When the brake is applied, the vehicle should be decelerated. The brake pedal is stepped on the push rod and the master cylinder piston to make the master cylinder oil Under a certain pressure, it flows into the wheel cylinder, and pushes the brake shoe around the support pin through the two-wheel cylinder piston. The upper end is separated to the two sides and the friction plate is pressed against the inner circular surface of the brake drum. The non-rotating brake shoe generates a frictional torque to the rotating brake drum, thereby generating a braking force.
The function of the brake master cylinder is to convert the mechanical energy input from the outside into hydraulic energy, so that the hydraulic energy can be transmitted to the brake wheel cylinder through the pipeline. The brake master cylinder is mainly double-cavity and is used for single and double-circuit hydraulic brake systems. Double chamber brake master cylinder 1) Structure (such as series double chamber brake master cylinder in BJ1041 hydraulic brake system)
The brake system is mainly composed of a brake, a hydraulic transmission mechanism and the like. As long as the wheel brake has a rotating portion and a fixed portion to form the brake drum with the inner circular surface as the working surface, it is fixed on the wheel hub and rotates together with the wheel. The support pins (two) are fixed to the stationary brake floor and supported at the lower ends of the two curved brake shoes. The outer surface of the brake shoe is also provided with a generally non-metallic friction lining. There is also a hydraulic brake wheel cylinder on the brake bottom plate, which is connected with a hydraulic brake master cylinder mounted on the frame. The brake master cylinder piston is operated by the driver via the brake pedal.
