Description

Technical Field

[0001] This utility model belongs to the field of floating brake calipers. Specifically, this utility model relates to a friction pad limiting structure for a brake caliper bracket. Background Technology

[0002] Existing disc brakes with floating calipers are prone to dragging, noise, and unnecessary energy loss; they also tend to generate braking noise during braking, which seriously affects the comfort of driving and causes noise pollution to the environment. Therefore, the above problems need to be solved.

[0003] The existing technology has the following drawbacks: 1. The current structural design usually has only one spring plate that fixes the friction plate in the brake caliper bracket. The return of the friction plate requires an additional return spring. The return spring forces on both sides are often not synchronized, which leads to inconsistent active return of the friction plate, which can easily cause drag and noise. 2. The circumferential limit of the friction pad is a mechanical limit. If the gap between the friction pad and the caliper bracket is too large, it is easy for the friction pad to hit the brake caliper bracket during braking, causing abnormal noise. 3. Current friction pad wear alarms typically use mechanical or electronic alarms. The alarm principle of existing technologies is that the alarm can only be triggered after the brake caliper bracket comes into contact with the brake disc, which can easily cause damage to the brake disc.

[0004] Utility model patent CN218882853U, published on April 18, 2023, discloses a brake caliper bracket. The bracket body has a buffer element at the point where the braking tangential force applies. A groove structure is formed on the bracket body corresponding to the position of the buffer element, with the buffer element fixed within and protruding from the groove structure. However, this brake caliper bracket does not completely solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by providing a friction pad limiting structure for a brake caliper bracket that improves braking noise and reduces brake disc damage.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: The friction pad limiting structure of the brake caliper bracket includes a bracket body, the bracket body includes a mounting groove, the end of the friction pad is located in the mounting groove, a damping unit is provided on the mounting groove, and an alarm unit is provided on the friction pad.

[0007] The mounting groove includes a platform and a sidewall, the platform and the sidewall are arranged perpendicularly, the damping unit includes a vulcanized rubber layer, the vulcanized rubber layer is disposed on the sidewall, and the vulcanized rubber layer is located on one side of the end of the friction plate.

[0008] The damping unit also includes a vulcanized rubber spring, which is mounted on the platform and has its end face in contact with one side of the friction plate.

[0009] The alarm unit includes an electronic alarm, and the vulcanized rubber spring has a through hole in the middle, with one end of the electronic alarm extending into the through hole.

[0010] The electronic alarm is equipped with external wires.

[0011] The electronic alarm is equipped with a positioning step, which is in contact with the electronic alarm.

[0012] The vehicle includes the friction pad limiting structure of the aforementioned brake caliper bracket.

[0013] The technical effects of this utility model are as follows: The friction pad limiting structure of the brake caliper bracket of this utility model, by setting a vulcanized rubber layer at the mounting groove, can effectively improve the impact noise of the friction pad hitting the caliper bracket, and at the same time improve the braking noise; a rubber spring is also used at the mounting groove to provide the return force for the friction pad, while increasing the axial damping and improving the braking noise; through the contact between the electronic alarm and the caliper bracket, dynamic contact with rotating parts can be effectively avoided, thereby avoiding damage to the friction surface of the brake disc.

[0016] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of this invention, and to facilitate its implementation.

[0017] like Figure 1As shown, the friction pad limiting structure of the brake caliper bracket includes a bracket body 1, which includes a mounting groove 3. The end of the friction pad 2 is located within the mounting groove 3. A damping unit is provided on the mounting groove 3, and an alarm unit is provided on the friction pad 2. The mounting groove 3 serves as the limiting position for the friction pad 2 on the bracket body 1. By providing damping to the friction pad 2 through the damping unit, noise reduction is achieved. Furthermore, no redesign or modification of other structures of the bracket body 1 is required, which helps reduce design costs.

[0018] like Figure 2 As shown, the mounting groove 3 includes a platform 4 and a side wall 5. The platform 4 and the side wall 5 are arranged perpendicularly. The damping unit includes a vulcanized rubber layer 6, which is located on the side wall 5 and on one side of the end of the friction pad 2. The side wall 5 of the mounting groove 3 serves as a lateral limiting position for the friction pad 2, i.e., a radial limiting position. The platform 4 and the bracket body 1 are an integral structure, which can constrain the space on one side of the mounting groove 3. By setting a vulcanized rubber layer 6 on the side wall 5, damping is provided for the friction pad 2 in the circumferential direction, which can effectively solve the impact noise of the existing disc brake during braking, thereby improving braking noise. When the gap between the friction pad 2 and the bracket body 1 is too large, the vulcanized rubber layer 6 can solve the problem of the friction pad 2 impacting the brake caliper bracket and causing abnormal noise. A limiting step 12 is provided at one end of the vulcanized rubber layer 6 on the mounting groove 3, which forms a groove structure with the platform 4, which is conducive to the firm fixation of the vulcanized rubber layer 6 in the mounting groove 3.

[0019] like Figure 2 and Figure 3 As shown, the damping unit also includes a vulcanized rubber spring 7, which is mounted on the platform 4. The end face of the vulcanized rubber spring 7 contacts one side of the friction plate 2. The platform 4 serves as the axial limiting position for the friction plate 2. The vulcanized rubber spring 7 is positioned here as a return spring. The vulcanized rubber spring 7 is extensible and can deform and compress under force, providing a return force for the friction plate 2. This provides damping for the friction plate 2 in the axial direction, effectively improving the problems of braking drag and high-frequency noise.

[0020] like Figure 4 As shown, the alarm unit includes an electronic alarm 9. A through hole 8 is provided in the middle of the vulcanized rubber spring 7, and one end of the electronic alarm 9 extends into the through hole 8. An electronic alarm 9 is installed on the back plate of the friction pad 2. When the friction pad 2 wears to a certain extent, during braking, the end of the electronic alarm 9 extending into the through hole 8 becomes the sensing end of the alarm. The sensing end of the alarm is shorter than the depth of the through hole 8. When it contacts the platform 4, it conducts current, transmitting a signal through the wire 10 to the vehicle's instrument panel lights, thus providing an alarm warning to the driver. The electronic alarm 9 can be a commonly used contact sensor or contact-type sensing element.

[0021] The working principle of the electronic alarm 9 is as follows: When the friction pad 2 has not worn down to the thickness required for replacement, during vehicle braking, the friction pad 2 is pushed by the hydraulic push rod, and the vulcanized rubber spring 7 undergoes a certain deformation, until it contacts the brake disc to brake the vehicle. However, the sensing end of the electronic alarm 9 will not contact the platform 4, so no alarm will be triggered. After the vehicle has been used for a period of time, the thickness of the area of ​​the friction pad 2 that is used to contact the brake disc for braking decreases, while the structure of the friction pad 2 in the mounting groove 3 area is a non-braking area, and the thickness of this area remains unchanged. Therefore, during vehicle braking, the stroke of the hydraulic push rod increases, and the vulcanized rubber spring 7 also undergoes greater deformation, causing the sensing end of the electronic alarm 9 to contact the platform 4, thereby connecting the current and transmitting a signal to the vehicle instrument through the wire 10. Subsequently, the instrument will display a light prompt to replace the friction pad 2, thus preventing the friction pad 2 from continuing to wear down and causing damage due to dynamic contact between the brake disc and the bracket.

[0022] like Figure 1 and Figure 4 As shown, the electronic alarm 9 is externally equipped with a wire 10. The wire 10 is used to transmit the alarm signal from the electronic alarm 9 to the vehicle's instrument panel lights, alerting the driver to replace the friction pad 2.

[0023] like Figure 4 As shown, the electronic alarm 9 is equipped with a positioning step 11, which contacts the electronic alarm 9. This structure serves to position the electronic alarm 9, thereby ensuring the reliability of its operation.

[0024] The vehicle includes the friction pad limiting structure of the aforementioned brake caliper bracket.

[0025] The friction pad limiting structure of the brake caliper bracket effectively reduces the impact noise of the friction pad 2 hitting the caliper bracket by setting a vulcanized rubber layer 6 at the mounting groove 3, and also improves braking noise. A rubber spring is also used at the mounting groove 3 to provide return force for the friction pad 2, while increasing axial damping and improving braking noise. The contact between the electronic alarm 9 and the caliper bracket can effectively avoid dynamic contact with rotating parts, thereby avoiding damage to the brake disc friction surface.

[0026] The present invention has been described above by way of example with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention; or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
