Description
Technical field
The present invention relates to automotive parts technical field, specifically a kind of automobile brake hose rubber grommet.
Background technology
Usually be all provided with hydraulic brake system in modern automobile brake system, brake hose is the passage transmitted fast for realizing brake-pressure.Because brake hose is arranged on quiet Dynamic link library car chassis and suspension realizing brake piping, move by planned course for preventing brake hose, avoid producing with other bodywork parts and to interfere or destruction that path of motion departs near driving engine thermal source and brake hose causes braking failure, need on brake hose, to install rubber grommet additional, brake hose is fixed to motor vehicle assembly position to control the path of motion of brake hose.
But in real work, brake hose can be turned to and the External Force Acting of suspension up-and-down movement, for preventing sliding between rubber grommet and brake hose, common design is: one, during assembling, between brake hose and rubber grommet, add glue fix, but this design is when Long-Time Service, meeting temperature influence, causes Performance Decay and mutually slides; Two, employing is embossed on brake hose, but this design is when Long-Time Service, also can occur aging and mutually slide; Three, the diameter of bore of rubber grommet is adopted to be less than the interference fit of the diameter of brake hose, elastic recovery force by rubber grommet makes to produce friction force between brake hose and rubber grommet, but the bad control of this friction force and smaller, different diameters is too large, bad assembling between brake hose and rubber grommet and easily cause assembling rear cracking, different diameters is too little, then friction force is too little, does not have fixing effect.
Summary of the invention
The present invention is for overcoming the deficiencies in the prior art, the design of groove is increased in the inside of rubber grommet, by the design of groove, make application force be converted to favourable constrained force to increase, thus increase contact force, reach the effect improving contact surface friction force, stop brake hose and rubber grommet that the phenomenon of sliding occurs.
For achieving the above object, design a kind of automobile brake hose rubber grommet, comprise rubber grommet body, it is characterized in that: in rubber grommet body, lateral shaft is provided with endoporus to running through, the outer rim of endoporus is laid with some radial directions and axial groove, described radial direction and axial groove are circular groove, and width that is radial and axial groove is 2 ~ 4 millimeters, and the degree of depth that is radial and axial groove is 0 ~ 1 millimeter; Described rubber grommet body, endoporus and radial direction and axial groove are that rubber is made into integration.
Described radial direction and axial groove are at least 3 one group, and endoporus is at least laid with 3 groups.
A force analysis for automobile brake hose rubber grommet, loading process is as follows:
(1) by brake hose and rubber grommet body interference fit;
(2) under rubber grommet body is subject to the effect of external force F, stress point is A, when external force F is L to the distance of brake hose;
(3), when rubber grommet body is subject to external force F, antagonistic force N1 can be produced, therefore, antagonistic force N1=external force F × distance L1;
(4) due to the design of groove, when being subject to external force F, groove is easily out of shape, and can produce the second antagonistic force N2, according to distance L × external force F=second antagonistic force N2 × distance L2, therefore, second antagonistic force N2=(distance L × external force F) ÷ distance L2;
(5) draw thus, friction force f=(antagonistic force N1+ second antagonistic force N2) × fus.
Described distance L1 is the distance between antagonistic force N1 to external force F.
Described distance L2 is the distance between the second antagonistic force N2 to external force F.
Described fus is the friction coefficient between brake hose and rubber grommet body.
The present invention compared with the existing technology, increases the design of groove, by the design of groove in the inside of rubber grommet, make application force be converted to favourable constrained force to increase, thus increase contact force, reach the effect improving contact surface friction force, stop brake hose and rubber grommet that the phenomenon of sliding occurs.
When adopting the stressed stacked system of segmentation to replace whole end stressed, carrying skew causes contact surface reduce thus cause friction force to reduce; Adopt design to run through groove not only to play and be easy to expand and effect not easy to crack, and play the effect that the liquid being easy to be stored in endoporus when assembling is easy to volatilization, simultaneously when needs are reprocessed, the liquid sprayed at end face is easy to enter while inside can play the location of the quick travel after entering liquid, the effect fixing fast behind location and liquid is easy to volatilize.

Detailed description of the invention
The present invention is described further with reference to the accompanying drawings below.
As shown in Figure 1 to Figure 3, in rubber grommet body 1, lateral shaft is provided with endoporus 2 to running through, the outer rim of endoporus 2 is laid with some radial directions and axial groove 3, described radial direction and axial groove 3 are in circular groove, and width that is radial and axial groove 3 is 2 ~ 4 millimeters, the degree of depth that is radial and axial groove 3 is 0 ~ 1 millimeter; Described rubber grommet body 1, endoporus 2 and radial and axial groove 3 are made into integration for rubber.
Radial and axial groove 3 is at least 3 one group, and endoporus 2 is at least laid with 3 groups.
The opening angle at endoporus 2 two ends is 30 °.
As shown in Figure 4, the force analysis of traditional grommet is friction force f=antagonistic force N × fus; In figure, antagonistic force N=Ft bullet, Ft bullet is the back stretch after grommet assembling.
As shown in Figure 5, loading process of the present invention is as follows:
(1) by brake hose and rubber grommet body interference fit;
(2) under rubber grommet body is subject to the effect of external force F, stress point is A, when external force F is L to the distance of brake hose;
(3), when rubber grommet body is subject to external force F, antagonistic force N1 can be produced, therefore, antagonistic force N1=external force F × distance L1;
(4) due to the design of groove, when being subject to external force F, groove is easily out of shape, and can produce the second antagonistic force N2, according to distance L × external force F=second antagonistic force N2 × distance L2, therefore, second antagonistic force N2=(distance L × external force F) ÷ distance L2;
(5) draw thus, friction force f=(antagonistic force N1+ second antagonistic force N2) × fus.
Distance L1 is the distance between antagonistic force N1 to external force F.
Distance L2 is the distance between the second antagonistic force N2 to external force F.
Fus is the friction coefficient between brake hose and rubber grommet body.
As shown in Figure 6, in use, skid force is unstable for traditional grommet, although and adopt the mode improving friction coefficient, be also difficult to meet the demands.
As shown in Figure 7, due to the design of groove, skid force improves greatly, and highly stable.
Increase the design of groove in the inside of rubber grommet, by the design of groove, making application force be converted to favourable constrained force increases, thus increases contact force, reaches the effect improving contact surface friction force, stops brake hose and rubber grommet that the phenomenon of sliding occurs.
When adopting the stressed stacked system of segmentation to replace whole end stressed, carrying skew causes contact surface reduce thus cause friction force to reduce; Adopt design to run through groove not only to play and be easy to expand and effect not easy to crack, and play the effect that the liquid being easy to be stored in endoporus when assembling is easy to volatilization, simultaneously when needs are reprocessed, the liquid sprayed at end face is easy to enter while inside can play the location of the quick travel after entering liquid, the effect fixing fast behind location and liquid is easy to volatilize.
