Abstract
A kind of blind rivet brake block steel back, comprise steel backing main body, a described steel backing main body surface uniform mutually bonding with friction substrate is provided with several half counterbores, the steel backing main body one side surface mutually bonding with friction substrate is also fixed with some blind rivets, blind rivet is evenly arranged at around half counterbore, and the surface on blind rivet top is provided with cone shape hole; Due to blind rivet and the effect of cone shape hole being arranged at blind rivet, when steel backing main body and friction substrate are suppressed, blind rivet embeds friction substrate, therefore, it is possible to effectively improve the bond degree between steel backing main body and friction substrate, add the working life of brake block, decrease brake block and use the potential safety hazard being.
Description
Technical field
The utility model relates to a kind of brake block steel back, specifically relate to a kind of blind rivet brake block steel back, belong to automotive brake part field.
Background technique
Due to the development of society, the performance of vehicle and growing with each passing day several times of traveling, in order to increase the stability of the skidding of vehicle when running at high speed, disk type brake has become the brake system of current main flow.Disk type brake is made up of steel backing and friction substrate, in the manufacture and using process of automobile brake sheet, the quality of steel backing and friction substrate changes well the overall performance directly determining brake block, but steel backing and the quality of the bonding degree of friction substrate have directly felt the quality of brake block.
Traditional automobile brake sheet is all made by steel backing and friction substrate high temperature, the faying surface of steel backing and friction substrate is arranged in planar usually, therefore make the bond degree between steel backing and friction substrate not high, this brake block after long usage, even come off above steel backing because the deficiency of bond degree makes friction substrate loosen, had a strong impact on the safety traffic of vehicle.Also there is a kind of brake block steel back of hole structure in the market, the steel backing of this structure first stamps through hole on steel backing surface, then friction substrate compacting is got on, although increase the bond degree between steel backing and friction substrate like this, but this steel backing easily produces distortion when suppressing with friction substrate, the flatness on steel backing surface is differed, so not only have impact on the overall appearance of brake block, but also reduce the practical intensity of steel backing.
Summary of the invention
In order to overcome above-mentioned existing technical problem, the utility model provides a kind of blind rivet brake block steel back that effectively can improve bond degree between brake block steel back and friction substrate.
The utility model solves the technological scheme that its technical problem adopts: a kind of blind rivet brake block steel back, comprise steel backing main body, a described steel backing main body surface uniform mutually bonding with friction substrate is provided with several half counterbores, the steel backing main body one side surface mutually bonding with friction substrate is also fixed with some blind rivets, blind rivet is evenly arranged at around half counterbore, and the surface on blind rivet top is provided with cone shape hole.
Described blind rivet is that wedge shape is arranged, and the diameter on the top of blind rivet is greater than blind rivet is connected one end diameter with steel backing main body.
The quantity of described half counterbore is at least 1, and the quantity of blind rivet is 2 to 16.
The quantity of described half counterbore is 2, and the quantity of blind rivet is 16.
The degree of depth of described half counterbore is 2-4mm, and blind rivet exceeds steel backing body surfaces 2-5mm, and cone shape hole is 1-2mm relative to the degree of depth of blind rivet top end surface.
The degree of depth of described half counterbore is 3mm, and blind rivet exceeds steel backing body surfaces 3mm, and cone shape hole is 1mm relative to the degree of depth of blind rivet top end surface.
Described blind rivet and steel backing main body design for integral type.
The beneficial effects of the utility model are, structure is simple, effectively can improve the bond degree between steel backing main body and friction substrate, add the working life of brake block, decrease brake block and use the potential safety hazard being.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is the overall structure schematic diagram of the utility model embodiment.
Fig. 2 is the sectional view of the utility model A-A.
In figure: 1. steel backing main body, 2. half counterbore, 3. blind rivet, 4. cone shape hole.
Embodiment
In order to make technical problem to be solved in the utility model, technological scheme and beneficial effect clearly understand, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the utility model, and be not used in restriction the utility model.
As shown in Figure 1 to Figure 2, a kind of blind rivet brake block steel back, comprise steel backing main body 1, the described steel backing main body 1 one side surface mutually bonding with friction substrate is provided with several half counterbores 2, the steel backing main body 1 one side surface mutually bonding with friction substrate is also fixed with some blind rivets 3, blind rivet 3 is with steel backing main body 1 for integral type designs, and blind rivet 3 is evenly arranged at around half counterbore 2, and the surface on blind rivet 3 top is provided with cone shape hole 4.Blind rivet 3 is arranged in wedge shape, and the diameter on the top of blind rivet 3 is greater than blind rivet 3 is connected one end diameter with steel backing main body 1.The quantity of half counterbore 2 is 2, and the quantity of blind rivet 3 is 16.The degree of depth of half counterbore 2 is 3mm, and blind rivet 3 exceeds the surperficial 3mm of steel backing main body 1, and cone shape hole 4 is 1mm relative to the degree of depth of blind rivet 3 top end surface.
By adopting such scheme, first offer 2 half counterbores 2 at steel backing main body 1 surface uniform, and the degree of depth of half counterbore 2 is 3mm, then 16 blind rivets 3 are gone out at the back side of steel backing main body 1 at the peripheral location of two and half counterbores 2, namely around each half counterbore 2,8 blind rivets 3 are evenly provided with, blind rivet 3 exceeds the surperficial 3mm of steel backing main body 1, then goes out cone shape hole 4 at the top end surface of blind rivet 3, and cone shape hole 4 is 1mm relative to the degree of depth of blind rivet 3 top end surface.Adopt said structure, the utility model increases the area of contact between friction substrate and steel backing main body 1, also improve the bond degree between steel backing main body 1 and friction substrate, the utility model is had, and simple, between steel backing main body and friction substrate the bond degree of structure is high, long service life, the advantages such as potential safety hazard during use is few.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all do within spirit of the present utility model and principle any amendment, equivalent to replace and improvement etc., all should be included within protection domain of the present utility model.
