Description

Technical Field

[0001] This utility model relates to the technical field of brake pads, specifically a brake pad based on a high-viscosity, low-noise friction material. Background Technology

[0002] Brake pads are the most critical safety component in a car's braking system, and their performance determines the effectiveness of braking. However, existing brake pads are made of an adhesive heat insulation layer, friction blocks and steel plates connected together. When braking, the friction pads rub against the brake disc, which generates a lot of noise. This not only affects the surrounding environment, but also reduces the user experience, thus reducing the efficiency of the friction pads. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a brake pad based on a high-viscosity, low-noise friction material. This solves the problem that brake pads, which consist of an adhesive heat insulation layer, friction blocks, and steel plates connected together, generate significant noise during braking due to friction between the friction pad and the brake disc. This not only affects the surrounding environment but also reduces the user experience, thereby lowering the efficiency of the friction pad.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a brake pad based on a high-viscosity, low-noise friction material, comprising a base and a friction block. The friction block is disposed on the upper end of the base and is made of a high-viscosity, elastic friction material. A mounting seat is fixedly installed on the upper end of the base. A placement groove is provided inside the top surface of the mounting seat. Sound-absorbing cotton is fixedly installed inside the placement groove. The bottom of the friction block is fitted onto the upper end of the mounting seat and is tightly fitted with the sound-absorbing cotton.

[0005] Preferably, a gasket is fixedly installed between the base and the mounting base. The base, gasket, mounting base, and sound-absorbing cotton are all symmetrically provided with insertion holes at both ends. The positions of the insertion holes in the base, gasket, mounting base, and sound-absorbing cotton correspond to each other. Connecting columns are symmetrically fixedly installed at both ends of the bottom surface of the friction block. The connecting columns are slidably connected to the inside of the insertion holes and are wrapped by the sound-absorbing cotton, thereby improving the noise reduction effect of the friction block.

[0006] Preferably, each of the connecting columns is fixedly connected to a threaded column at its bottom, the threaded column extends to the lower end of the base, and a nut is threaded onto the outside of each threaded column. The nut is located at the lower end of the base, thereby enabling the friction block to be securely installed.

[0007] Preferably, the bottom of the threaded column is fitted with a sealing sleeve, which is fitted onto the lower end of the nut and pressed against the bottom of the nut, thereby preventing loosening of the installation between the friction blocks.

[0008] Preferably, the bottom of the friction block is sealed to the outer sidewall of the mounting base by a sealing gasket, thereby ensuring a tight connection between the friction block and the mounting base.

[0009] Preferably, the top of the sound-absorbing cotton extends to the upper outer part of the mounting base after installation, thereby facilitating a tight fit between the sound-absorbing cotton and the friction block.

[0010] This invention provides a brake pad based on a high-viscosity, low-noise friction material. It offers the following advantages: 1. This type of brake pad based on a high-viscosity, low-noise friction material can effectively reduce the noise generated by the friction block during braking by using the sound-absorbing cotton and the friction block. 2. This type of brake pad based on a high-viscosity, low-noise friction material can transmit the noise generated by the friction block during braking to the interior of the sound-absorbing cotton through the set connecting post, thereby further reducing noise generation.

Detailed Implementation

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0014] Please see Figure 1-3This utility model provides a brake pad based on a high-viscosity, low-noise friction material, including a base 1 and a friction block 3. The friction block 3 is disposed on the upper end of the base 1, and the friction block 3 is a high-viscosity elastic friction material. A mounting seat 2 is fixedly installed on the upper end of the base 1. A placement groove 6 is provided inside the top surface of the mounting seat 2, and a sound-absorbing cotton 7 is fixedly installed inside the placement groove 6. The bottom of the friction block 3 is sleeved on the upper end of the mounting seat 2, and the bottom is tightly fitted with the sound-absorbing cotton 7. A gasket 9 is fixedly installed between the base 1 and the mounting seat 2. The base 1, gasket 9, mounting base 2, and sound-absorbing cotton 7 all have symmetrically arranged insertion holes 8 at both ends. The positions of the insertion holes 8 in the base 1, gasket 9, mounting base 2, and sound-absorbing cotton 7 correspond to each other. The bottom surfaces of the friction block 3 are symmetrically fixed with connecting posts 10 at both ends. The connecting posts 10 are slidably connected to the inside of the insertion holes 8 and are wrapped by the sound-absorbing cotton 7. The bottom of each connecting post 10 is fixedly connected with a threaded post 11, which extends to the lower end of the base 1. Nuts 5 are threadedly sleeved on the outside of each threaded post 11. Located at the lower end of the base 1, the bottom of the threaded post 11 is sealed with a sealing sleeve 4, which is fitted onto the lower end of the nut 5 and pressed against the bottom of the nut 5. The bottom of the friction block 3 is sealed to the outer side wall of the mounting base 2 by a sealing gasket. The top of the sound-absorbing cotton 7 after installation extends to the upper outer side of the mounting base 2. When the friction block 33 rubs against the brake pad, the noise generated will be effectively reduced by the sound-absorbing cotton 7. At the same time, the noise generated will be transmitted to the connecting post 10. 10 is located inside the sound-absorbing cotton 7. By wrapping it with the sound-absorbing cotton 7, the generation of noise can be further effectively reduced. When installing the friction block 3, the connecting post 10 is inserted through the sound-absorbing cotton 7, the mounting base 2, the gasket 9 and the insertion hole 8 inside the base 1, until the threaded post 11 is moved to the lower end of the base 1. Then, the nut 5 is threaded onto the threaded post 11, which can make the position of the friction block 3 secure. Then, the sealing sleeve 4 is fitted onto the threaded post 11, which can effectively limit the position of the nut 5.

[0015] It should be noted that, in this embodiment, as Figure 1-3 As shown, when using the brake pad body, the noise generated by the friction block 33 rubbing against the brake pad is effectively reduced by the sound-absorbing cotton 7. At the same time, the noise is transmitted to the connecting post 10. Since the connecting post 10 is inside the sound-absorbing cotton 7, the noise generation can be further effectively reduced by the sound-absorbing cotton 7. When installing the friction block 3, the connecting post 10 is inserted into the holes 8 inside the sound-absorbing cotton 7, the mounting base 2, the gasket 9 and the base 1, until the threaded post 11 is moved to the lower end of the base 1. Then, the nut 5 is threaded onto the threaded post 11, which can make the position of the friction block 3 secure. Then, the sealing sleeve 4 is put onto the threaded post 11, which can effectively limit the position of the nut 5.
