What is the working principle of the ABS pump?
1 Answers
The working principle of the ABS pump is that when a large current is applied to the solenoid valve, the plunger moves to the upper end, the passage between the master cylinder and the wheel cylinder is cut off, and the wheel cylinder is connected to the hydraulic oil tank. The brake fluid in the wheel cylinder flows into the hydraulic oil tank, reducing the braking pressure. At the same time, the drive motor starts, driving the hydraulic pump to work, pressurizing the brake fluid that flows back to the hydraulic oil tank and delivering it to the master cylinder, preparing for the next braking cycle. The ABS pump is translated into Chinese as "Anti-lock Braking System" and, together with airbags and seat belts, is known as one of the three major inventions in automotive safety history. It is a vehicle safety control system with advantages such as anti-skid and anti-lock functions.
