Pressure filling installation structure and automobile braking system

Abstract

The invention relates to a pressure filling installation structure and an automobile braking system. The pressure filling installation structure comprises a kettle cover, a valve body and a valve needle, the kettle cover is arranged on the valve body in a sleeving mode, the valve needle for controlling opening and closing of the valve is arranged in a valve cavity of the valve body, and an elastic element is arranged between the valve body and the valve needle; the brake fluid pot is covered with the pot cover, the valve needle is pushed to be opened through pressure, liquid in the brake fluid pot is made to move into the pipeline so as to detect the sealing performance of the pipeline and / or exhaust residual gas in the pipeline, and when the pressure is removed, the elastic element pushes the valve needle to be closed. The invention further provides an automobile braking system. The automobile braking system comprises the pressure filling installation structure. The problems that residual gas exists in a brake fluid pipeline of a brake system of an existing modified or maintained vehicle, brake failure occurs in the running process of the vehicle, and therefore safe running of the vehicle is affected are solved.

Description

technical field [0001] The invention relates to the technical field of automobile modification or maintenance, in particular to a pressure filling installation structure and an automobile braking system. Background technique [0002] The braking system of an automobile is a very critical and important system to realize the safe operation and normal operation of the vehicle. Usually, the filling of brake fluid is done by vacuum filling equipment in the production line, and the pressure test and filling are completed through the method of vacuuming - maintaining pressure - filling. [0003] like figure 1 As shown, it is a schematic diagram of the brake fluid filling of the production line. 01 is the vacuum filling equipment. The filling process is as follows. First, the interface of the vacuum filling equipment 01 is connected and sealed with the brake fluid tank 02, and the filling equipment starts to pump Vacuum, when a certain degree of vacuum is reached, the brake system...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide a pressure filling installation structure and an automobile brake system to solve the problem of the brake system of the existing remodeled or repaired vehicle. There is residual gas in the dynamic fluid pipeline, which leads to brake failure during the operation of the vehicle, which affects the safe driving of the vehicle. It is also possible to perform a seal test on the brake fluid pipeline of the rebuilt or repaired vehicle
