What is the working principle of the car brake system?
With the ABS anti-lock system car after depressing the brake pedal, the brake fluid from the brake master cylinder through the ABS anti-lock control valve to the wheels of the brake to achieve the brake. The ABS anti-lock system will be based on the braking conditions (emergency braking or bad road braking brake hydraulic and other sensor signal changes) and quickly control the brake hydraulic changes, that is, the brake quickly brake, release , Then brake, and then release the process (we commonly known as the fast point of the brake, of course, the speed can not do), so as to prevent the wheel suddenly locked and cause the vehicle flick or slip to ensure the safety of the driver.
Overview of the working principle of the car brake The function of the car brake system is to make the driver according to the road and traffic, etc., in order to make the road to the wheel to exert a certain force, the car to a certain degree of forced braking to meet the driver's driving needs The The brake system is mainly composed of energy supply device, control device, transmission device, brake force adjustment device and brake. Brake in the brake system is used to produce obstacles to the movement of the vehicle or movement of the force of the components, can be divided into two kinds of drum and disc. Today's cars also have a central brake (hand brake), mainly used for parking brake. Due to the different structural and physical characteristics, the current drum brakes are generally used in heavy-duty vehicles, and light cars almost all use disc or front disc rear drum brakes (modern disc brakes are composed of brake discs and brake calipers , So called chuck-type brakes, commonly known as brake calipers)
The general principle of the braking system is to prevent the rotation or rotation of the wheels by the mutual friction between the non-rotating elements associated with the vehicle body (or frame) and the rotating elements connected to the wheels (or drive shafts). Brake system does not work when there is a gap between the drum, the wheel and the brake drum can be free to rotate the brake when the car deceleration, pedal brake pedal through the putter and the master cylinder, so that the main cylinder of oil under a certain pressure into the wheel And the brake shoe is rotated about the support pin by the two-wheel cylinder piston, and the upper end is separated from both sides and pressed against the inner surface of the brake drum with its friction plate. Does not turn the brake shoe on the rotating brake drum friction torque, resulting in braking force to lift the brake when the release of the brake pedal back when the brake shoe is back to the original position, the braking force disappears.
