Abstract
A low-noise disc-typed brake includes a brake clamp, a shaft pin and a frame; one end of the shaft pin is fixed to the brake clamp; while the other end of the shaft pin is movably arranged in the frame; a shaft pin dustproof sleeve is arranged between the shaft pin and the frame; one end of the shaft pin dustproof sleeve is arranged in the external installation trough of the shaft pin. The utility model is characterized in that the other end of the dustproof sleeve is arranged in the internal wall of the frame; a drop-proof mechanism is arranged between the dustproof sleeve and the frame. The utility model has the advantages of good sealing performance and convenient and reliable application. The water and impurity grains can be prevented from entering the matching surface between the surface and the shaft pin, the vibration and noise can also be effectively reduced, the abrasion between the frame and the shaft pin can be relieved, and the service life can be prolonged.
Description
(1), technical field
The utility model relates to a kind of component of motor-rehicle braking system, particularly a kind of low noise formula disk type braker.
(2), background technique
At present, traditional disk type braker, brake calipers, pivot pin and support have been generally comprised, one end of pivot pin is fixed on the brake calipers, the other end activity be positioned at support, be provided with the pivot pin dirt-proof boot between pivot pin and the support, these pivot pin dirt-proof boot two ends lay respectively in the outer mounting groove on pivot pin and the support, have certain interval between pivot pin and the support.Above-mentioned pivot pin dirt-proof boot can prevent that sealing or impurity particle enter the fitting surface of support and pivot pin, reaches purpose dustproof, waterproof.But because brake calipers generally is floating type installation, the gap that exists between support and the pivot pin, in the vehicle driving process, thereby this cooperation place is shaken the generation noise easily, when Motor Vehicle travelled on the relatively poor road surface of road conditions such as hollow, this noise can become bigger because of the reinforcement of vibrations.In addition, for full-metallic contacts, easily be worn between support and the pivot pin, reduced the working life of break.
(3), summary of the invention
The purpose of this utility model just provides a kind of good airproof performance, easy to use and reliable low noise formula disk type braker, it can prevent that not only sealing and impurity particle etc. enter the fitting surface of support and pivot pin, can also effectively reduce the vibrations noise, slow down the wearing and tearing between support and the pivot pin, prolong working life.
The purpose of this utility model is to realize by such technological scheme, it includes brake calipers, pivot pin and support, one end of pivot pin is fixed on the brake calipers, the other end activity be positioned at support, be provided with the pivot pin dirt-proof boot between pivot pin and the support, one end of this pivot pin dirt-proof boot is positioned at the outer mounting groove on the pivot pin, it is characterized in that: the other end of dirt-proof boot is installed in rack inner wall, is provided with escapement between described dirt-proof boot and the support.
Above-mentioned escapement can be arranged on the anticreep draw-in groove that anticreep Ka Tai on the dirt-proof boot and corresponding anticreep Ka Tai are arranged on rack inner wall; Also can be arranged on the anticreep Ka Tai that anticreep draw-in groove on the dirt-proof boot and corresponding anticreep draw-in groove are arranged on rack inner wall.
Anticreep Ka Tai and anticreep draw-in groove cooperating to each other, can prevent effectively that sealing and impurity particle enter the fitting surface of support and pivot pin, avoid therefore and the corrosion and the wearing and tearing that produce.And embed between support and the pivot pin because dirt-proof boot is a part of, reduced the area of support and pivot pin Metal Contact face, make it when further wearing and tearing between minimizing pivot pin and the support, also obviously reduced vibrations noise between the two.
(4), description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is a kind of embodiment's of the utility model a structural representation;
Fig. 2 is the cutaway view Amplified image of A-A among Fig. 1;
Fig. 3 is the another kind of embodiment's of the utility model a structural representation;
Fig. 4 is the cutaway view Amplified image of B-B among Fig. 3;
Among the figure: 1. brake calipers; 2. pivot pin; 3. support; 4. pivot pin dirt-proof boot; 5. outer mounting groove; 6. anticreep Ka Tai; 7. anticreep draw-in groove; 8. vent slot.
(5), embodiment
The utility model is described in further detail below in conjunction with drawings and Examples:
Shown in Fig. 1 or 2, the utility model includes brake calipers 1, pivot pin 2 and support 3, one end of pivot pin 2 is fixed on the brake calipers 1, the other end activity be positioned at support 3, be provided with pivot pin dirt-proof boot 4 between pivot pin 2 and the support 3, one end of this pivot pin dirt-proof boot 4 is positioned at the outer mounting groove 5 on the pivot pin 2, it is characterized in that: the other end of dirt-proof boot 4 is installed in support 3 inwalls, is provided with escapement between described dirt-proof boot 4 and the support 3.
As shown in Figure 1, escapement is arranged on the anticreep card platform 6 on the pivot pin dirt-proof boot 4 and is arranged on the anticreep draw-in groove 7 that matches with anticreep card platform 6 on the support 3.
As shown in Figure 3, escapement is arranged on the anticreep draw-in groove 7 on the pivot pin dirt-proof boot 4 and is arranged on the anticreep card platform 6 that matches with anticreep draw-in groove 7 of support 3 inwalls.
Shown in Fig. 3 or 4, for the ease of the installation between pivot pin 2 and the support 3, pivot pin dirt-proof boot 4 is provided with vent slot 8.
Claims (4)
