Description

Technical Field

[0001] The utility model belongs to the technical field of automobile distribution valves and relates to a distribution valve capable of waterway switching. Background Art

[0002] The automobile distribution valve is an important part of the air-fuel subsystem in the hydraulic brake system. Its main functions are as follows: the automobile distribution valve is responsible for receiving the fluid from the hydraulic pump and distributing the fluid flow to each branch duct according to the needs of the brake. The automobile distribution valve distributes the fluid evenly to the injector of each cylinder through the internal fluid channel to ensure that each branch duct can obtain the right amount of fluid. The automobile distribution valve is a key component in the automobile braking system. Its main function is to distribute and switch the brake fluid to achieve the braking function of the vehicle. If the automobile distribution valve cannot distribute and switch the fluid, a series of serious problems will occur.

[0003] Failure of the distribution valve will result in the brake fluid not being distributed to each brake as required, resulting in uneven or insufficient braking force. This will directly extend the braking distance and increase the risk of accidents. In emergency braking situations, uneven distribution of braking force may cause the wheels to lock, leading to serious consequences such as loss of control, skidding or rollover of the vehicle.

[0004] Failure of the distribution valve may cause abnormal noise, vibration or abnormal pedal feeling in the brake system. These problems not only affect the driver's comfort, but also may make the driver lose confidence in the brake system, further affecting driving safety. Therefore, a water-channel switchable distribution valve is urgently needed to solve the above problems. Utility Model Content
