As shown in fig. 1-3, the utility model provides a brake disc end runout adjustment gasket for place install in the middle of brake disc and bearing to the runout that adjustment brake disc 3 terminal surface 31 exists is out of tolerance when the assembly. The brake disc end jump shim, in general, may comprise an annular shim body 1. The gasket body 1 is made of rubber material, metal material and the like. The gasket body 1 is provided with a plurality of through holes 2 for the brake disc 3 to pass through by mounting bolts. The gasket body 1 is provided with a convex structure 4. The protruding height of the protruding structure 4 is not larger than the end face runout tolerance of the brake disc 3. The shim body 1 is used for installing and positioning the brake disc end jump adjusting shim between the brake disc and the bearing. The raised structure 4 is used for compensating the end face run-out tolerance of the brake disc 3. Optionally, the protruding structure 4 is disposed between two adjacent through holes 2. The gasket body 1 is also provided with a positioning hole 5. The positioning holes 5 and the through holes 2 are alternately arranged. In a specific embodiment, a positioning hole 5 is formed in the center of the protruding structure 4. The arrangement of the positioning holes 5 can effectively prolong the service life of the gasket. When detecting the end jump out of tolerance, can combine the concrete position of out of tolerance, place brake disc end jump adjusting shim and install in the middle of brake disc 3 and bearing, wherein, need face to the direction of out of tolerance protruding structure 4 to carry out the decoupling zero to the end jump stack, after finally guaranteeing brake disc 3 loading, realize the end jump compensation, make the end jump be in comparatively ideal scope.
Specifically, the utility model provides a brake disc end jump adjusting shim as shown in fig. 3, gasket body 1 includes first face 11, second face 12 and side 13. In a particular embodiment, the raised structures 4 are provided on the first face 11 avoiding the through-holes 2. Alternatively, the raised structures 4 may also be disposed on opposite positions of the first face 11 and the second face 12, respectively. It should be understood that the utility model provides a brake disc end jump adjusting shim, its protruding structure 4's effect is the compensation of realizing the end jump, and the effect of gasket body 1 is the stability of the installation location who improves the gasket, increases its life-span during use. If the structure of the gasket body 1 is removed, only the protruding structure 4 exists, the effect of end jump compensation adjustment can be achieved, the service life is short only due to the fact that the fixed point of the gasket body 1 is lacked, the gasket is easy to lose efficacy, and the gasket can be used in a short-period bench test.
As shown in fig. 4, the brake disc 3 is mounted on the bearing in a state of being mounted on the actual vehicle, and the ideal mounting state is that the end face 31 of the brake disc 3 jumps very little after the brake disc 3 is mounted on the vehicle. However, as can be seen from fig. 4, in a real vehicle, the end jump of the brake disc 3 is often very large, beyond a reasonable range, under the influence of various factors. In addition, even if the dimensions of the individual pieces are acceptable, there is a possibility that the end jumps of the bearing and the brake disk 3 are superimposed, and the end jumps of the brake disk are amplified by the bearing, resulting in an out-of-tolerance. And the utility model provides a brake disc end jumps adjusting shim is exclusively used in the end of brake disc 3 promptly and jumps the adjustment. As shown in fig. 5, the brake disc assembly diagram after installing the end-jump adjusting shim of the brake disc of the present invention is shown. The principle is as follows: at the superposition position of the brake disc 3 and the bearing end jump, the brake disc end jump adjusting shim is installed, so that the end jump superposition is decoupled, and finally, the end jump is ensured to be in a more ideal range after the brake disc 3 is loaded.
The utility model provides a brake disc end is jumped adjusting shim can improve assembly efficiency, jumps the end of brake disc and controls at extremely low within range, even stack with the bearing like this, the assembly end is jumped and also can not be too big, can greatly practice thrift the cost.
The utility model provides a brake disc end is jumped adjusting shim when being used for the 4S shop to reprocess, when the user appeared the travelling comfort and complain, the brake disc was disassembled in the 4S shop, reprocesses after sale to the brake disc, need not the friction surface of turning brake disc, only need assemble suitable brake disc end jump adjusting shim can to with assembly end jump control in reasonable within range. The method can prevent the trouble in the bud, reduce the repair cost, better ensure the satisfaction degree of users and maintain the brand image of products.
The above description is only for the preferred embodiment of the present invention, and is not intended to limit the present invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included within the protection scope of the present invention.
