Problems solved by technology

Moreover, the existing brake pads are generally fixed by means of friction pads sticking to the steel back. During use, the friction pads are easy to fall off from the steel back under the action of shear force.
If the brake pads fall off during driving, the consequences will be disastrous

Embodiment Construction

[0011] refer to figure 1 , the present invention proposes a low-noise alarm disc brake pad, including a steel plate 1 and a friction plate 2, wherein:

[0012] The friction plate 2 is fixed on the steel plate 1, and the side of the steel plate 1 close to the friction plate 2 is provided with a plurality of first grooves 3, and the side of the friction plate 2 close to the steel plate 1 is provided with the first groove 3 at a position corresponding to the first groove 3. The second groove 4 connected to the groove 3, the first groove 3 is provided with a boss 5 integrally formed with the steel plate 1, the height of the boss 5 is equal to the sum of the depth of the first groove 3 and the second groove 4, the steel plate 1 is located below the boss 5 and is provided with cooling holes 8 and the boss 5 is penetrated by the cooling holes 8 , and the number of the cooling holes 8 is consistent with the number of the bosses 5 . The first groove 3 is provided with a sound-absorbin...

Abstract

The invention provides a low-noise alarming disc type brake pad which comprises a steel plate and a friction sheet, wherein the friction sheet is fixed on the steel plate; multiple first grooves are formed in one side, which is close to the friction sheet, of the steel plate; second grooves communicating with the first grooves are formed in positions, which correspond to the first grooves, on one side, which is close to the steel plate, of the friction sheet; convex pillars integrated with the steel plate are arranged in the first grooves; the height of each convex pillar is equal to a depth sum of the first grooves and the second grooves; silencing sheets arranged on the convex pillars in a sleeving manner are arranged in the first grooves; and alarming sheets arranged on the convex pillars in a sleeving manner are arranged in the second grooves. According to the low-noise alarming disc type brake pad, by the arrangement of the silencing sheets in the first grooves, noise generated in a friction process of the brake pad and a brake disc can be effectively reduced; and first assembling holes are formed in the steel plate, and second assembling holes are formed in the friction sheet, so that the friction sheet and the steel plate are fixed together through connection pillars and elastic collars, and falling of the friction sheet can be effectively prevented.

Description

technical field [0001] The invention relates to the technical field of motor vehicle brakes, in particular to a low-noise alarm disc brake pad. Background technique [0002] Brake pads are the executive components that perform braking while the car is running. The brake pads clamp the brake disc that rotates with the tires, and the brake pads rub against the brake disc to convert the driving kinetic energy of the car into heat energy, thereby realizing the braking of the car. operate. During the braking process, severe noise will be generated when the brake pads rub against the brake disc. Moreover, the existing brake pads are generally fixed by means of the friction pads being stuck on the steel back, and the friction pads are easy to fall off from the steel back due to the shear force during use. If the brake pads fall off during driving, the consequences will be disastrous. Contents of the invention [0003] Based on the technical problems existing in the background ...
