[Auto Repair Knowledge]What is ABS? The working principle and common sense of ABS

ABSIt is an improved technology based on conventional braking devices.It works by relying on highly sensitive wheels mounted on each wheelRotating speedsensorAnd the speed of the car on the bodysensor, Controlled by computer. During emergency braking, once a wheel is found to be locked, the computer immediately instructs the pressure regulator to release (decrease) the pressure of the wheel's brake cylinder and restore the rotation of the wheel. The working process of abs is actually a cycle of lock-release-lock-release, so that the vehicle is always in a critical lock gap rolling state, effectively overcoming the deviation, sideslip, and throwing during emergency braking. Tail, to prevent the car body from getting out of control and other situations. 1. When ABS is braking, the high-speed retracting and releasing action of the brake cylinder will cause the high-pressure brake fluid to be frequently squeezed and produce a louder sound.Brake pedalThere will also be jitter and top foot phenomenon.Don’t be bothered by this phenomenon while driving. In an emergency, use abs to brake without hesitation.brakeStep on the bottom, you can't relax. 2. Because the wheels do not lock up during ABS emergency braking, the front wheels still have a guiding role, so the driver can brake and steer for emergency avoidance. 3. The abs system has very high requirements for brake fluid. Therefore, adding brake fluid should strictly follow the requirements in the instruction manual. Generally, it is forbidden to mix different types of brake fluid. Generally speaking, the brake fluid of the same model should be replaced once a year. You can also use dot3 or dot4 alcohol-based brake fluid. 4. The abs wheel sensor and gear ring are installed on each wheel, so always keep the sensor probe and gear ring clean to prevent mud, oil, and especially magnetic substances from adhering to the surface, which will cause the sensor to fail or lose. The signal to the computer is wrong and affects the normal operation of the abs system. 5. Vehicles equipped with abs system should strictly follow the regulationstireAir pressure standard while maintaining coaxialtireTo balance the air pressure, it is strictly forbidden to use tires of different specifications. In addition, pay attention to check the gap between the wheel speed sensor probe and the ring gear. Excessive axial gap of the wheel bearing will directly affect the normal operation of abs. 6. When driving, the driver should always pay attention to the abs warning light on the dashboard. If it flickers or stays on, it means that the abs system is out of working state.at this timeBraking SystemIt has returned to the normal brake work interface. The car can continue to drive, but it no longer has the abs function. It is recommended to overhaul it as soon as possible.
