Description
Technical Field
The utility model relates to a brake master cylinder with tank assembly in the technical field of automobile brake systems, in particular to a connecting sleeve of the brake master cylinder with tank assembly, which is mainly applied to brake systems of cars and micro-cars.
Background
The existing brake master cylinder assembly with a tank for automobile braking mainly comprises a liquid storage tank assembly, a brake master cylinder assembly, a connecting sleeve and a fixing screw (pin). The liquid storage tank assembly is used for storing brake liquid, and is used for replenishing the brake liquid for each brake pipeline in the braking process and monitoring the storage amount of the brake liquid in the brake pipeline. When the brake liquid level reaches the critical value of the system, the liquid storage tank can send out a signal to prompt the replenishment of the brake liquid. As shown in fig. 3, the adapter sleeve 1 serves as the only rubber member connecting the reservoir assembly 2 and the master cylinder assembly 3, and not only serves to support the reservoir assembly, but also serves to provide sealing for both.
As shown in fig. 4, the conventional connecting sleeve 1 is composed of a thick lip 101 with supporting function, an R-shaped inner sealing ring belt 102 and an R-shaped outer sealing ring belt 103 which are matched with the oil outlet nozzle of the liquid storage tank assembly and the oil inlet hole of the brake master cylinder assembly respectively. The thick lip 101 is a ring with a height of 4.16mm and an angle of 3 ° and 5 ° respectively, where manufacturability is poor and efficiency is low during assembly. The inner and outer R-shaped sealing ring belts are respectively matched with the oil outlet nozzle of the liquid storage tank assembly and the oil inlet hole of the brake master cylinder assembly to realize the sealing effect of the assembly, and the reliability of the brake master cylinder assembly with the tank is required to be ensured without leakage. With the continuous development of the structure and the appearance of the liquid storage tank assembly, the brake master cylinder with tank assembly has higher requirements on the structure and the performance of a sealing element connecting sleeve in the whole vehicle use, and the connecting sleeve structure can not meet the assembly and use requirements of the existing liquid storage tank assembly at present.
Disclosure of Invention
The utility model provides a connecting sleeve of a brake master cylinder with a tank assembly, which solves the problems that the assembly manufacturability of the existing connecting sleeve is poor, and the sealing performance cannot meet the continuous development of the brake master cylinder with the tank assembly.
The technical scheme adopted by the utility model is as follows: the bottom surface of the lip edge of the connecting sleeve, which is contacted with the brake master cylinder assembly, is a plane, the upper surface contacted with the liquid storage tank assembly comprises an inner low plane, an outward inclined plane and an outer high plane, two R-shaped sealing ring belts are arranged at the matched sealing surface of the liquid storage tank assembly oil outlet nozzle, and three R-shaped sealing ring belts are arranged at the matched sealing surface of the liquid storage tank assembly oil inlet hole.
The lip thickness H is 3mm.
The included angle alpha between the inclined plane and the vertical line is 30 degrees.
The utility model has the advantages that the structure is novel, the structure of the connecting sleeve is optimized, the thick lip of the original liquid storage tank assembly and the brake master cylinder assembly which are matched with each other is thinned, and the inclined plane is changed into the plane, so that the structure has good assembly property in assembly, reduces the assembly process difficulty, improves the production efficiency and reliability, and adds one and two R-shaped sealing ring belts at the matched sealing surface with the liquid storage tank assembly oil outlet nozzle and the brake master cylinder assembly oil inlet hole respectively.

Detailed Description
As shown in fig. 1, the bottom surface of the lip 101 of the connecting sleeve 1, which is contacted with the brake master cylinder assembly, is a plane 10101, the upper surface contacted with the liquid storage tank assembly comprises an inner low plane 10102, an outward inclined plane 10103 and an outer high plane 10104, two R-shaped sealing ring bands 102 are arranged at the matched sealing surface of the liquid storage tank assembly nozzle, and three R-shaped sealing ring bands 103 are arranged at the matched sealing surface of the liquid storage tank assembly oil inlet hole.
As shown in FIG. 1, the lip 101 has a thickness H of 3mm.
As shown in fig. 1, the inclined plane 10103 forms an angle α with the vertical line of 30 degrees.
Principle of operation
As shown in figure 2, the original thick lip of the supporting function of the liquid storage tank assembly and the brake master cylinder assembly is thinned, and the circular ring formed by inclined planes with the angles of the thick lip being 3 degrees and 5 degrees respectively is changed into an inclined plane, so that the structure has good assembly property in assembly, reduces the difficulty of assembly process, improves the production efficiency and reliability, and can meet the requirement of the brake master cylinder belt tank assembly used by various vehicle types on the tightness by adding one and two R-shaped sealing ring belts at the matched sealing surfaces of the liquid storage tank assembly oil outlet nozzle and the brake master cylinder assembly oil inlet hole.
