[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Traditional brake housings have two through holes: an oil inlet and a bleed hole. Under normal operating conditions, the oil inlet pipe is removed by loosening (tightening) the oil inlet bolt, and excess air is removed by loosening (tightening) the bleed hole. These two operating conditions are independent and are carried out separately.

[0022] To address this disassembly and assembly situation, this utility model designs a brake inlet pipe mounting bolt structure with venting function, combining the vent screw and the inlet pipe bolt venting structure to form an integrated oil inlet and venting system. Brake fluid flows through the oil inlet through hole of this new structure, and gas is expelled through the threaded hole of the vent screw.

[0023] like Figures 2-4 As shown, the structure includes an exhaust function oil inlet pipe mounting bolt 1, a vent screw 2, and an oil inlet hose assembly 3. One end of the exhaust function oil inlet pipe mounting bolt 1 is connected to the external brake assembly 4 via a thread, and the other end of the exhaust function oil inlet pipe mounting bolt 1 is connected to the vent screw 2. An oil hole is opened in the middle of the exhaust function oil inlet pipe mounting bolt 1, and the oil hole is connected to the oil inlet hose assembly 3.

[0024] like Figure 1 As shown, the exhaust function oil inlet pipe mounting bolt 1 has an exhaust bolt oil inlet through hole A and an exhaust bolt vent screw thread hole B sequentially opened along its own axial direction. The exhaust bolt oil inlet through hole A and the exhaust bolt vent screw thread hole B are arranged coaxially and directly connected. At the same time, the exhaust bolt oil inlet through hole A has a radial hole with side connection in the middle, and the radial hole is connected to the built-in through hole of the oil inlet hose assembly 3.

[0025] like Figure 2 As shown, the vent screw threaded hole B of the venting function oil inlet pipe mounting bolt 1 and the vent screw 2 are fitted together by thread to form a threaded conical surface sealing connection, which avoids oil leakage and improves the versatility of the vent screw 2.

[0026] The diameter of the oil inlet hole A of the vent bolt is smaller than the diameter of the threaded hole B of the vent bolt vent screw. A step is formed between the oil inlet hole A of the vent bolt and the threaded hole B of the vent bolt vent screw. The vent screw 2 is used to tightly connect to the step to block the flow between the oil inlet hole A of the vent bolt and the threaded hole B of the vent bolt vent screw.

[0027] The inner end of the vent screw 2 is threaded to the vent screw threaded hole B of the vent bolt, and the outer end is equipped with a dust cover.

[0028] like Figure 3 As shown, the oil inlet hole A of the vent bolt is connected to the radial hole and the built-in through hole of the oil inlet hose assembly 3 to form a brake fluid channel for brake fluid flow, ensuring brake fluid circulation and improving the stability of the braking system.

[0029] like Figure 4As shown, the external brake assembly 4 has a brake inlet mounting hole C. A venting function inlet pipe mounting bolt 1 is installed at the brake inlet mounting hole C. The end of the venting function inlet pipe mounting bolt 1, located at the venting bolt inlet through-hole A, is threaded to the brake inlet mounting hole C. This installation and mating of the brake inlet mounting hole C with the brake assembly 4 effectively reduces the time required for disassembling and assembling the venting bolt 1 and vent screw 2, improving the efficiency of disassembling the inlet hose assembly 3 and venting the vent screw 2.

[0030] The oil inlet mounting hole C of the external brake assembly 4 is a universal hole that integrates oil inlet and venting, eliminating the need for a venting hole, reducing the machining cost of the brake venting hole, and providing more space for the overall vehicle and other brake arrangements.

[0031] The implementation process of this utility model is as follows:

[0032] First, the vent screw 2 is installed and fitted through the threaded hole B of the vent screw to form a threaded connection and a conical surface seal.

[0033] Secondly, the oil inlet hole A connects to the built-in through hole of the oil inlet hose assembly 3 to form a brake fluid passage, ensuring the flow of brake fluid;

[0034] The external part is installed and fitted with the brake assembly 4 through the brake oil inlet mounting hole C, which effectively reduces the time for disassembly and assembly of the oil inlet pipe mounting bolt 1 and the air venting screw 2 during the venting process, and improves the venting efficiency of disassembly and assembly of the oil inlet hose assembly 3 and the air venting screw 2.

[0035] Finally, the oil inlet mounting hole C of the external brake assembly 4 is a universal hole for both oil inlet and exhaust.

[0036] Example:

[0037] During the bleeding process of vehicle braking system debugging, maintenance, and bench testing, the brake system undergoes two independent processes: loosening / tightening the oil inlet bolt and bleed screw to remove excess air. These processes are time-consuming and inefficient. The current solution integrates the functions of the oil inlet bolt and bleed screw, sharing a common oil inlet mounting hole. This eliminates interference between the bleed screw bleed and oil inlet bolt bleed functions, reducing the bleeding and disassembly time by at least 15-20 minutes. It also eliminates the need for a separate bleed hole in the brake system, lowering machining costs and providing more space for other aspects of the vehicle and brake system layout.

[0038] As can be seen from the implementation, this utility model has a simple structure and is easy to implement. It can effectively reduce the time spent disassembling and assembling the oil inlet pipe bolt and the vent screw for venting, eliminate the processing cost of the brake vent hole, and provide more space for the layout of the whole vehicle and other brake components.
