Description

Technical Field

[0002] Brake knocking noise is a relatively common brake noise. The sound source is the friction pad hitting the brake caliper bracket. The friction pad is installed on the brake caliper bracket. There is a certain gap between the side of the friction pad and the side of the brake caliper bracket. When the vehicle brakes, the brake caliper bracket drives the friction pad and the brake pad on the wheel to rub and contact, which causes the brake pad to exert a large lateral force on the friction pad, causing the side of the friction pad to repeatedly hit the side of the brake caliper bracket. In order to suppress brake knocking noise, the industry currently uses the following method: filling grease in the gap between the side of the friction pad and the side of the brake caliper bracket to reduce the knocking noise. As time goes by, the grease is easy to evaporate and dry, so that the grease can no longer suppress the knocking noise. Utility Model Content

[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] like Figures 1-4 As shown, the embodiment of the present application provides a device for eliminating brake knocking noise, which is applied to the brake knocking noise in the brake system. The brake knocking noise is the brake noise generated during the braking process. This phenomenon is relatively common. The reason is that the friction plate 80 repeatedly hits the brake caliper bracket 90. In the brake system, the friction plate 80 is installed on the brake caliper bracket 90. There is a certain assembly gap between the side of the friction plate 80 and the side of the brake caliper bracket 90. When the vehicle brakes, the brake caliper bracket 90 drives the friction plate 80 to rub against the brake pad on the wheel. Under the reaction force, the brake pad of the wheel hits the friction plate 80. 0 applies a large friction force, which causes the side of the friction plate 80 to repeatedly hit the side of the brake caliper bracket 90. The way to solve the brake knocking noise in the industry is to fill grease in the gap between the side of the friction plate 80 and the side of the brake caliper bracket 90, relying on the damping force of the grease to reduce the knocking noise. This method has certain defects. As time goes by, the grease is easy to evaporate and dry out, and the grease is significantly reduced, and it can no longer play the role of suppressing the knocking noise. The brake knocking noise elimination device of the present application is intended to improve the long-term and effective elimination of the knocking noise generated during the braking process.

[0024] The brake knocking noise elimination device is arranged between the side of the brake caliper bracket 90 and the side of the friction plate 80. The brake knocking noise elimination device includes a connecting portion, an abutting portion 100 and a connecting section. The connecting portion is used to connect with the side of the brake caliper bracket 90 in the brake system, and the abutting portion 100 is used to abut against the side of the friction plate 80. The connecting portion, the abutting portion 100 and the connecting section are connected together, and the connecting section is connected between the connecting portion and the abutting portion 100, that is, the connecting portion and the abutting portion 100 are connected through the connecting section, and the connecting section is elastic, so that the abutting portion 100 and the connecting portion are elastically connected. Under the action of the elastic force, the abutting portion 100 and the side of the friction plate 80 are elastically abutted. In this embodiment, the brake caliper bracket An elastic abutment is formed between the side of the frame 90 and the side of the friction plate 80, so that a damping effect is formed between the side of the brake caliper bracket 90 and the side of the friction plate 80, thereby effectively suppressing the brake knocking noise, and the connecting part, the abutting part 100 and the connecting section have a long service life. Compared with volatile and easy-to-air-dry grease, the brake knocking noise elimination device can effectively eliminate the knocking noise of the vehicle system for a long time. Specifically, along the direction of the reaction force of the brake pad on the friction plate 80 on the wheel, a brake knocking noise elimination device is provided on the upstream side of the friction plate 80 and the downstream side of the friction plate 80, so that there is a damping effect between the two sides of the friction plate 80 and the brake caliper bracket 90, which is conducive to improving the noise elimination effect.

[0025] Preferably, the connecting portion includes a first section 201, a second section 202 and a third section 203, the second section 202 is connected between the first section 201 and the third section 203, the first section 201 is used to connect to the brake caliper bracket 90, one end of the connecting section is connected to the abutting portion 100, and the other end of the connecting section is connected to the second section 202. In this embodiment, the connecting portion also includes a first transition section 301 and a second transition section 302. The first section 201 and the second section 202 are connected by the first transition section 301, and the third section 203 and the second section 202 are connected by the first transition section 301. Connected by the second transition section 302, the first section 201, the first transition section 301, the second section 202, the second transition section 302 and the third section 203 are connected end to end in sequence and form a "J" shape, so as to adapt to the protruding structure on the side of the friction plate 80 and the recessed structure of the brake caliper bracket 90. In practice, a protruding structure is provided on the side of the friction plate 80, and a recessed structure is provided on the brake caliper bracket 90. The protruding structure of the friction plate 80 is adapted to the recessed structure of the brake caliper bracket 90, thereby improving the stability of the friction plate 80. The "J" shape is conducive to adaptation in the gap.

[0026] The first section 201, the first transition section 301, the second section 202, the second transition section 302 and the third section 203 are all plate-like structures, and the first section 201 and the first transition section 301 are vertically connected, the first transition section 301 and the second section 202 are vertically connected, the second section 202 and the second transition section 302 are vertically connected, and the second transition section 302 and the third section 203 are vertically connected. Along the direction of the "J" shape, the length of the first section 201, the length of the first transition section 301, the length of the second section 202, the length of the second transition section 302 and the length of the third section 203 can be freely set as long as it adapts to the gap between the friction plate 80 and the brake caliper bracket 90. The first section 201, the first transition section 301, the second section 202, the second transition section 302 and the third section 203 are an integrally formed structure. In this way, the structural integrity is stronger, which is conducive to improving the strength of the components. Moreover, it can be formed by continuously bending a whole piece of plate, which is conducive to reducing production costs.

[0027] More preferably, the abutting portion 100 is a plate-like structure, and the abutting portion 100 and the second section 202 are spaced apart and arranged in parallel, and one end of the abutting portion 100 is connected to the end of the connecting section. The abutting portion 100 of the plate-like structure can increase the contact area with the friction plate 80 and improve the matching stability. In this embodiment, the abutting portion 100 is an elongated plate-like structure, and the abutting portion 100 is a long plate. One end of the connecting section is connected to one end of the second section 202, and the other end of the connecting section is connected to one end in the longitudinal direction of the abutting portion 100. The other end in the longitudinal direction of the abutting portion 100 extends toward the other end opposite to the second section 202. That is, the abutting portion 100 and the second section 202 are connected by the connecting section, so that the abutting portion 100 and the second section 202 form a folded posture, but the abutting portion 100 and the second section 202 are spaced apart and arranged in parallel. In this way, a buffer gap is formed between the abutting portion 100 and the second section 202, which is conducive to producing a damping effect on the friction plate 80.

[0028] Preferably, the connecting section includes two arc-shaped connecting arms 401, one end of the connecting arm 401 is connected to the second section 202, and the other end of the connecting arm 401 is connected to the abutment 100. The material of the connecting arm 401 is an elastic material, for example, it can be carbon steel, chrome vanadium steel or silicon manganese steel, etc. More preferably, the first section 201, the first transition section 301, the second section 202, the second transition section 302, the third section 203, the two connecting arms 401 and the abutment 100 are an integrally formed structure, and the overall material is an elastic material, which further enhances the damping effect between the brake caliper bracket 90 and the friction plate 80.

[0029] After the brake knocking noise elimination device is arranged between the friction plate 80 and the brake caliper bracket 90, the first section 201 is connected to the side of the brake caliper bracket 90, the outside of the first transition section 301, the outside of the second section 202, the outside of the second transition section 302 and the outside of the third section 203 all abut against the side of the brake caliper bracket 90, and the protruding structure of the friction plate 80 abuts against the abutting portion 100.

[0030] In this embodiment, the connecting arm 401 is in an arc shape, specifically a semicircular shape, so that the abutting portion 100 and the second section 202 are folded in half, and the two connecting arms 401 are arranged at intervals. A tongue 501 bent toward the second section 202 is provided on the abutting portion 100 in the area between the two connecting arms 401. One end of the tongue 501 is connected to the abutting portion 100, and the other end is inclined and extended in the direction of the second section 202 and away from the abutting portion 100. In this way, after the brake knocking noise elimination device is arranged between the friction plate 80 and the brake caliper bracket 90, the protruding structure of the friction plate 80 abuts against the abutting portion 100, and there is a certain pre-tightening force between the protruding structure of the friction plate 80 and the abutting portion 100, so that the end of the abutting portion 100 away from the connecting arm 401 abuts against the second section 202, so that the friction plate 80 and the brake caliper bracket 9 0 generates an elastic damping force between them. When the brake is applied, under the reaction force of the brake pad on the wheel, for the brake knocking noise elimination device on the downstream side of the force direction, the friction plate 80 squeezes the abutment 100. On the one hand, the connecting arm 401 generates a stronger elastic reaction force, and the abutment 100 also generates elastic deformation and generates an elastic reaction force. If the connecting arm 401 is severely deformed, the tongue 501 will move with the abutment 100 and touch the side of the brake caliper bracket 90 against which the second section 202 abuts, thereby playing an elastic limiting role. For the brake knocking noise elimination device on the opposite side, under the elastic force of the connecting arm 401, the abutment 100 slightly pushes the friction plate 80, so that the friction plate 80 produces an obvious damping effect between the brake caliper bracket 90, preventing the friction plate 80 and the brake caliper bracket 90 from colliding, thereby effectively suppressing the generation of brake knocking noise.

[0031] More preferably, a contact pin 601 is provided on the second transition section 302, and the end of the contact pin 601 protrudes from the side of the second transition section 302 away from the first transition section 301, that is, the end of the contact pin 601 protrudes from the outer surface of the outer side of the second transition section 302, and the contact pin 601 has a certain elastic deformation ability. In this way, the part composed of the first transition section 301, the second section 202 and the second transition section 302 is squeezed into the recessed structure of the brake caliper bracket 90. Relying on the elastic deformation ability of the contact pin 601, the end of the contact pin 601 can form a reverse hook engagement with the side wall of the recessed structure of the brake caliper bracket 90, which is more convenient for installation. In this embodiment, one end of the contact pin 601 is connected to the second section 202, and the end of the contact pin 601 extends to the area of ​​the second transition section 302 and protrudes outside the second transition section 302, and the end of the contact pin 601 faces the third section 203 , and extends obliquely in the direction of rotation. More preferably, a through groove 602 is provided at the junction of the second section 202 and the second transition section 302, and the contact foot 601 is in the through groove 602, and one end of the contact foot 601 is connected to one side of the second section 202, and the other end of the contact foot 601 first extends toward the second transition section 302 along the plane where the second section 202 is located, and then extends obliquely toward the third section 203, and the end of the contact foot 601 protrudes outward from the second transition section 302. In this way, when squeezing into the recessed structure of the brake caliper bracket 90, the contact foot 601 is deformed so that the end of the contact foot 601 is retracted to the outside of the second transition section 302 to a certain extent. After being fully squeezed in, a barbed reverse hook matching structure is formed between the contact foot 601 and the side of the brake caliper bracket 90, which makes the matching more stable. More preferably, the end of the contact foot 601 can be forked to improve the barbed matching strength.

[0032] More preferably, two connecting feet 700 are provided at the end of the first section 201, and the connecting feet 700 and the first section 201 are connected vertically to each other, and the extension direction of the connecting feet 700 on the first section 201 is the same as the extension direction of the first transition section 301 on the first section 201, that is, the connecting feet 700 and the first section 201 are connected vertically, and the connecting feet 700 and the first transition section 301 are located on the same side of the first section 201, and the connecting feet 700 and the first transition section 301 have the same extension direction on the same side of the first section 201. In this way, after the brake knocking noise elimination device is installed on the friction plate 80 and the brake caliper bracket 90, the first section 201 is abutted against the side of the brake caliper bracket 90, and the connecting feet 700 are inserted into the side of the brake caliper bracket 90 to improve the connection strength.
