Description

Technical Field

[0001] The utility model belongs to the technical field of anti-skid pumps for automobiles, and particularly relates to an anti-skid pump capable of increasing the amount of pump fluid. Background Art

[0002] Automobile anti-skid pumps usually refer to hydraulic pumps installed in automobile braking systems to prevent wheels from slipping during braking and improve vehicle driving safety and handling stability. The amount of pump fluid in the anti-skid pump determines the magnitude of the braking force, but the existing anti-skid pumps have a small and fixed pump fluid volume, which can provide sufficient braking effect in daily use. However, the actual working scenarios of automobiles are different, and greater braking effect is required in some emergency situations, especially when driving on ice, snow and other roads. Wheel slippage will increase the probability of accidents, and in severe cases, more tragic traffic accidents will occur.

[0003] Secondly, insufficient fluid in the anti-skid pump may lead to low work efficiency in actual work, causing the early anti-skid performance to be unstable and unable to improve the stable anti-skid braking effect, resulting in insufficient vehicle performance and unable to guarantee the driving experience and driving safety of the driver and passengers.

[0004] In summary, the automobile anti-skid pump has some problems in use due to its small pumping amount of fluid, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
