Abstract
The invention discloses a brake pad having an alarm function. The brake pad having the alarm function comprises a steel backing, a friction block is fixed to the lower end surface of the steel backing, and an alarm piece is arranged at the right end of the steel backing. The alarm piece is provided with an elastic piece portion and an elastic clamping groove clamped with the right end of the steel backing. The elastic clamping groove comprises a bottom, an upper side wall portion tightly attached to the upper end surface of the steel backing, and a lower side wall portion tightly attached to the lower end surface of the steel backing. The upper side wall portion is bent back after being bent upwards, then, the upper side wall portion extends downwards to an alarm position formed after the friction block is abraded, and the elastic piece portion is located at the right side of the elastic clamping groove. A groove is formed in the upper end surface of the steel backing, the position, corresponding to the groove, of the upper side wall portion is provided with a stamping hole, and a material in the stamping hole is overturned downwards and clamped into the groove in order to prevent the elastic clamping grove from falling off from the right end of the steel backing.
Description
Technical field
The present invention relates to a kind of brake block with warning function.
Background technique
Automotive disc brake comprises brake disc and brake block, can wear and tear, change brake block and usually cause waste, and check brakes sheet is cumbersome according to distance travelled number after brake block uses a period of time.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the deficiency in prior art, provides a kind of brake block with warning function.
The technical solution adopted for the present invention to solve the technical problems is: a kind of brake block with warning function, comprise steel backing, steel backing lower end surface is fixed with brake pad, steel backing right-hand member is provided with alarm, alarm has shrapnel part, with the elasticity draw-in groove of steel backing right-hand member clamping, elasticity draw-in groove comprises bottom, be close to the upside wall portion of steel backing upper-end surface and be close to the A lower side wall portion of steel backing lower end surface, the upwards back bending after bending of upside wall portion, then the alarm point extended downward after brake pad wearing and tearing forms shrapnel part, shrapnel part is positioned on the right side of elasticity draw-in groove, described steel backing upper-end surface is provided with groove, wall portion respective slot place, described upside is provided with punching hole, turn under material in punching hole and snap in groove to stop elasticity draw-in groove to come off from steel backing right-hand member.
Brake pad of the present invention the invention has the beneficial effects as follows: when may wear to warning thickness, brake disc starts to swipe the lower end of shrapnel part, sends harsh noise, reminds driver to change brake block in time, with guarantee driving safety, thus it also avoid the trouble that driver needs running check brake block.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
In figure: 1. steel backing; 2. brake pad; 3. elasticity draw-in groove; 4. wall portion on the upside of; 5. shrapnel part; 6. groove.
Embodiment
The present invention is further illustrated with preferred embodiment by reference to the accompanying drawings now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
A kind of brake block with warning function as shown in Figure 1, comprise steel backing 1, steel backing 1 lower end surface is fixed with brake pad 2, steel backing 1 right-hand member is provided with alarm, alarm has shrapnel part 5, with the elasticity draw-in groove 3 of steel backing 1 right-hand member clamping, elasticity draw-in groove 3 comprises bottom, be close to the upside wall portion 4 of steel backing 1 upper-end surface and be close to the A lower side wall portion of steel backing 1 lower end surface, the upwards back bending after bending of upside wall portion 4, then the alarm point extended downward after brake pad 2 wearing and tearing forms shrapnel part 5, shrapnel part 5 is positioned on the right side of elasticity draw-in groove 3, the perpendicular distance of shrapnel part 5 lower end to steel backing 1 lower end surface is less than the thickness of brake pad 2, described steel backing 1 upper-end surface is provided with groove 6, wall portion 4 respective slot 6 place, described upside is provided with punching hole, turn under material in punching hole and snap in groove 6 to stop elasticity draw-in groove 3 to come off from steel backing 1 right-hand member.
When alarm is installed, while steel backing 1 right-hand member is snapped in elasticity draw-in groove 3, should guarantee that the material turned under in punching hole snaps in groove 6 to prevent alarm from coming off from steel backing 1 right-hand member.
Above-described embodiment is only for illustrating technical conceive of the present invention and feature; its object is to person skilled in the art can be understood content of the present invention and be implemented; can not limit the scope of the invention with this; all equivalences done according to Spirit Essence of the present invention change or modify, and all should be encompassed in protection scope of the present invention.
