Description

Technical Field

[0001] The present application relates to the technical field of brake caliper brackets, and in particular to a brake caliper bracket capable of reducing vibration and noise. Background Art

[0002] The brake caliper assembly plays a crucial role in modern automotive braking systems, and the caliper bracket, as a key component, is directly impacting the performance and reliability of the entire braking system. When the vehicle brakes, the caliper bracket must withstand a complex system of forces generated by the intense friction between the friction pad and the brake disc, including but not limited to axial and radial forces, as well as the resulting vibration loads. The combined effects of these forces place stringent demands on the caliper bracket's structural strength, rigidity, and stability.

[0003] Existing brake caliper brackets, when resisting the various forces and vibrations generated during braking, experience creep—a small but continuous relative displacement between the caliper bracket and adjacent components. This creep not only causes unpleasant noise, reducing driver and passenger comfort, but more seriously, it can also impair the overall stability and reliability of the braking system, accelerating the wear of related components and shortening the service life of the entire braking system.

[0026] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application. It should be noted that, in the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other in any way.

[0027] The brake caliper assembly plays a crucial role in modern automotive braking systems, and the caliper bracket, as a key component, is directly impacting the performance and reliability of the entire braking system. When the vehicle brakes, the caliper bracket must withstand a complex system of forces generated by the intense friction between the friction pad and the brake disc, including but not limited to axial and radial forces, as well as the resulting vibration loads. The combined effects of these forces place stringent demands on the caliper bracket's structural strength, rigidity, and stability.

[0028] Existing brake caliper brackets, when resisting the various forces and vibrations generated during braking, experience creep—a small but continuous relative displacement between the caliper bracket and adjacent components. This creep not only causes unpleasant noise, reducing driver and passenger comfort, but more seriously, it can also impair the overall stability and reliability of the braking system, accelerating the wear of related components and shortening the service life of the entire braking system.

[0029] Based on this, an exemplary embodiment of the present application provides a brake caliper bracket with shock absorption and noise reduction, which includes a brake caliper bracket body, a support pin mounting seat and a buffer pad mounting seat provided on the brake caliper bracket body, and a support pin mounting hole formed in the support pin mounting seat; by installing a buffer pad on the buffer pad mounting seat, the impact force and vibration energy generated during braking can be absorbed and dissipated, and the vibration can be effectively prevented from being transmitted to the vehicle body or the suspension system, thereby reducing the noise caused by vibration; by installing a support pin dust cover in the support pin mounting hole, the vibration energy in the brake caliper bracket body can be converted during braking, thereby suppressing the resonance phenomenon of the brake caliper bracket.

[0030] An exemplary embodiment of the present application provides a brake caliper bracket with vibration reduction and noise reduction, such as Figures 1 to 4As shown, the brake caliper bracket includes a caliper bracket body 10, which is provided with symmetrically arranged support pin mounting seats 101. Support pin mounting holes are formed within the support pin mounting seats 101. Support pin dust covers 20 are installed in the support pin mounting holes. Support pins 30 are mounted within the support pin dust covers 20. Support pin dust covers 20 convert vibration energy generated during braking into heat and dissipate it, thereby suppressing resonance in the caliper bracket. A buffer pad mounting seat 102 is formed on the side of the support pin mounting seats 101 opposite the support pin mounting holes. A buffer pad 40 is mounted on the buffer pad mounting seat 102. The buffer pad 40 absorbs and dissipates the impact force and vibration energy generated during braking, effectively preventing vibration from being transmitted to the vehicle body or suspension system, thereby reducing noise caused by vibration. A shock-absorbing sleeve is also provided at the bottom of the support pin mounting holes. The end of the support pin 30 is sleeved within the shock-absorbing sleeve. The shock-absorbing sleeve converts vibration generated during braking, suppressing resonance in the caliper bracket.

[0031] like Figure 5 As shown, the buffer pad mounting seat 102 includes a positioning portion 1021 and a mounting portion 1022. The positioning portion 1021 is provided on the end surface of the support pin mounting seat 101. Preferably, the positioning portion 1021 is a cylindrical boss, and its end surface is the positioning surface of the buffer pad 40. The mounting portion 1022 is provided on the end surface of the positioning portion 1021 and is concave inwardly toward the positioning portion 1021 to form a mounting hole for the buffer pad 40. The buffer pad 40 includes a top wall, side walls, and mounting struts. The mounting struts are provided on the top wall and are located in the mounting space enclosed by the side walls and the top wall. The mounting struts are adapted to the mounting hole of the buffer pad 40, and the mounting struts are installed in the mounting hole of the buffer pad 40. The buffer pad 40 is preferably made of nitrile rubber or silicone rubber, which has a high elastic modulus and good damping properties and can effectively absorb and dissipate vibration energy.

[0032] like Figure 6 and 7 As shown, the support pin dust cover 20 includes a first mounting section 201 and a second mounting section 202 connected in sequence; a support pin mounting hole is formed in the first mounting section 201 and the second mounting section 202; the first mounting section 201 includes an inner layer portion 203 embedded in the support pin mounting hole and an outer layer portion 204 covering the outside of the inner layer portion 203, the inner layer portion 203 and the outer layer portion 204 are connected to each other, and an accommodating space for accommodating the support pin mounting seat 101 is formed between the inner layer portion 203 and the outer layer portion 204. The double sealing of the embedded inner layer portion 203 and the outer layer portion 204 significantly improves the sealing effect between the support pin dust cover 20 and the brake caliper bracket. Preferably, as Figure 7 As shown, the free end of the outer portion 204 forms a second annular protrusion 208 inwardly; Figure 5As shown, a second annular groove 1011 is formed on the support pin mounting seat 101; the size of the second annular groove 1011 is adapted to the size of the second annular protrusion 208; when the support pin dust cover 20 is installed in the support pin mounting hole, the second annular protrusion 208 is embedded in the second annular groove 1011, so that the support pin mounting seat 101 can be stuck in the accommodating space, and the support pin dust cover 20 is tightly matched with the brake caliper bracket, which can ensure the stability and reliability of the installation between the support pin dust cover 20 and the brake caliper bracket, and improve the sealing performance between the support pin dust cover 20 and the brake caliper bracket.

[0033] like Figure 6 and 7 As shown, the second mounting section 202 includes a stretching portion 205 connected to the outer portion 204 and a fitting portion 206 disposed on the top of the stretching portion 205; the top of the fitting portion 206 forms a first annular protrusion 207 inwardly; Figure 5 As shown, a first annular groove 301 is formed on the upper outer wall of the support pin 30; the size of the first annular groove 301 is adapted to the size of the first annular protrusion 207; when the support pin 30 is installed in the support pin dust cover 20, the first annular protrusion 207 is embedded in the first annular groove 301, so that the support pin 30 and the support pin dust cover 20 are tightly fitted, thereby improving the sealing performance between the support pin 30 and the support pin dust cover 20.

[0034] Preferably, the stretching portion 205 has a stretched state and a non-stretched state; during the operation of the brake caliper, each time the brake is applied, the support pin 30 will slide relative to the support pin mounting seat 101, and when the support pin 30 slides out of the support pin mounting hole, the support pin 30 will drive the stretching portion 205 to move together, so that the stretching portion 205 is in a stretched state, and in the stretched state, the inner wall of the stretching portion 205 fits the outer wall of the support pin 30; when the braking is completed, the support pin 30 returns to the initial state, that is, the support pin 30 is completely installed in the support pin mounting hole, at this time, the stretching portion 205 is in a non-stretched state, and in the non-stretched state, the stretching portion 205 forms a multi-layer stack in the direction away from the axis of the support pin 30.

[0035] During installation of the support pin 30, due to the extremely small gap between the outer dimensions of the support pin 30 and the dimensions of the support pin mounting hole, a small amount of lubricant is typically applied to the outside of the support pin 30 to facilitate installation. During installation of the support pin 30, it is necessary to exhaust the air within the support pin mounting hole. In one embodiment, to facilitate the exhaust of air within the support pin mounting hole during installation of the support pin 30, a plurality of concave exhaust channels 209 are provided on the inner wall of the inner layer portion 203. This allows air within the support pin mounting hole to be exhausted through the exhaust channels 209 during installation of the support pin 30, preventing deformation of the support pin dust cover 20 during installation.

[0036] In one embodiment, Figure 6 As shown, the outer walls of the first mounting section 201 and the second mounting section 202 are both provided with a buffering and shock absorbing portion 210 to suppress the vibration of the brake caliper bracket and improve the stability and reliability of the braking system.

[0037] In this application, the terms "comprises," "comprising," or any other variations thereof are intended to encompass non-exclusive inclusion, such that an article or device comprising a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such article or device. In the absence of further limitations, an element defined by the phrase "comprising..." does not exclude the presence of additional identical elements in the article or device comprising the element.

[0038] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications that fall within the scope of the present application.
