Description

Technical Field

[0001] This invention relates to the field of braking system technology, and specifically to a brake caliper. Background Technology

[0002] Electromechanical braking systems (EMB), as a modern alternative to traditional hydraulic calipers, have gained attention with the development of electric vehicles and autonomous driving technologies. Currently, EMB electronic brake calipers are directly mounted on the wheel ends, replacing the original hydraulic braking system. They use electrical wiring instead of hydraulic lines and transmit signals from the pedal to the actuator via electronic signals, offering advantages such as fast response, high efficiency, small size, and light weight.

[0003] The basic structure of a brake caliper includes a caliper body and a caliper support. The two ends of the caliper body are axially slidably connected to the caliper support via guide pins. A dust cover (also called a dust shield) is installed on the guide pin between the caliper body and the caliper support to prevent debris from entering the gap between the guide pin and the caliper body, thus ensuring the smooth movement of the caliper body. For example, patent document CN 119196194A discloses a brake caliper assembly.

[0004] According to data from car dealers, the lifespan of dust covers on brake calipers is significantly shorter in northern regions than in southern regions. In particular, during winter vehicle testing in 2025, the lifespan of dust covers on brake calipers was significantly shorter compared to factory testing.

[0005] Therefore, how to improve the service life of the dust cover on the brake caliper and ensure the normal use of the brake caliper has become a technical problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the purpose of the present invention is to provide a brake caliper that addresses the above-mentioned technical problems, thereby extending the service life of the dust cover on the brake caliper and ensuring the normal use of the brake caliper.

[0008] The guide pin connects the caliper bracket and the brake caliper, and the dust cover is fitted onto the guide pin;

[0009] A protective body is provided on the caliper bracket or brake caliper body. The axial position of the protective body is directly opposite the axial position of the dust cover. When the brake caliper is installed on both sides of the brake disc, the distance from the protective body to the axis of the brake disc is greater than the distance from the dust cover to the axis of the brake disc.

[0010] Preferably, the protective body is a protective plate disposed on the back of the brake caliper body.

[0011] Preferably, the protective plate is integrally formed on the back of the brake caliper body, and the protective plate extends along the radial direction of the brake disc.

[0012] Preferably, the protective body is an arc-shaped plate disposed at the end of the brake caliper body, and the arc-shaped plate is located on one side of the dust cover.

[0013] Preferably, when the brake caliper is installed on both sides of the brake disc, the arc-shaped plate is located at the end of the brake caliper body where it is in a higher position.

[0014] Preferably, the protective body is an arc-shaped plate disposed at the end of the clamp body bracket, and the arc-shaped plate is located on one side of the dust cover.

[0015] Preferably, when the brake caliper is installed on both sides of the brake disc, the arc-shaped plate is located at the end of the caliper bracket where it is in a high position.

[0016] Preferably, the protective body is a protective post disposed at the end of the clamp support.

[0017] Preferably, the protective column is integrally formed on one or both ends of the clamp body bracket.

[0018] Preferably, the brake caliper body is provided with a first guide hole, the guide pin passes through the first guide hole, and one end of the guide pin is connected to the caliper body bracket; one end of the dust cover is connected to the brake caliper body, and the other end of the dust cover is connected to the caliper body bracket or the guide pin.

[0019] Preferably, the brake caliper further includes a protective cover and a mounting bolt. One end of the guide pin abuts against the caliper body bracket. The mounting bolt is disposed in the connecting through hole to the guide pin. The connecting end of the mounting bolt is threadedly connected to the caliper body bracket. The nut end of the mounting bolt abuts against the guide pin. The protective cover is disposed on the periphery of the other end of the guide pin and is connected to the brake caliper body.

[0020] Preferably, the caliper bracket is provided with a second guide hole, the guide pin passes through the second guide hole, and one end of the guide pin is connected to the brake caliper; one end of the dust cover is connected to the brake caliper or the guide pin, and the other end of the dust cover is connected to the caliper bracket.

[0021] The beneficial effects of this invention are:

[0022] This invention provides a protective body on the brake caliper body and caliper support. The protective body and the dust cover are positioned axially on the brake caliper, and the distance between the protective body and the brake disc axis is greater than the distance between the dust cover and the brake disc axis. This allows the protective body to be positioned radially between the wheel rim and the dust cover during wheel rotation. This prevents ice and snow adhering to the wheel rim from rubbing against the dust cover, thus protecting the dust cover and extending its service life. Attached Figure Description

[0035] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. These embodiments are for illustrative purposes only and are not intended to limit the scope of the invention.

[0036] In the description of this invention, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0038] Furthermore, in the description of this invention, unless otherwise stated, "a plurality of" means two or more.

[0039] Specific embodiment 1, such as Figures 1-3 , Figure 6 As shown, a brake caliper 100 includes: a caliper bracket 110, a brake caliper body 120, a guide pin 130, and a dust cover 140.

[0040] Two first guide holes 121 are provided on the brake caliper body 120, and the two first guide holes 121 are located at the two ends of the brake caliper body 120 respectively.

[0041] There are two guide pins 130, and the two guide pins 130 are inserted one-to-one into the two first guide holes 121. One end of the guide pin 130 extends axially to the outside of the brake caliper body 120 and is fixedly connected to the caliper body bracket 110.

[0042] There are two dust covers 140, which are fitted one-to-one on the two guide pins 130. The dust covers 140 are located between the two ends of the brake caliper body 120 and the two ends of the caliper support 110. One end of the dust cover 140 is connected to the brake caliper body 120, and the other end of the dust cover 140 is fixedly connected to the caliper support 110 or the guide pin 130. That is, the other end of the dust cover 140 can be indirectly fixedly connected to the caliper support 110 through the guide pin 130.

[0043] A protective body 150 is provided on the brake caliper body 120. The axial position of the protective body 150 is directly opposite to the axial position of the dust cover 140. That is, in the circumferential direction, the protective body 150 and the dust cover 140 are spaced apart. In the axial direction, the position of the protective body 150 is the same as that of the dust cover 140. When the brake caliper 100 is installed on both sides of the brake disc 200, the distance from the protective body 150 to the axis of the brake disc is greater than the distance from the dust cover 140 to the axis of the brake disc.

[0044] Preferred, such as Figure 3 As shown, the protective body 150 is configured as a protective plate 151 integrally formed on the back of the brake caliper body 120, and the protective plate 151 extends along the radial direction of the brake disc 200. The radial distance from the outermost end of the protective plate 151 to the axis of the brake disc is greater than the radial distance from the outermost end of the dust cover 140 to the axis of the brake disc. This is so that when the ice and snow that are stuck to the rim 300 rotate with the wheel during vehicle operation, they first come into contact with the outer end of the protective plate 151. Through the friction between the protective plate 151 and the ice and snow on the rim 300, the length of the ice and snow on the rim 300 is prevented from increasing and colliding or rubbing against the dust cover 140, thereby protecting the dust cover 140 and extending its service life.

[0045] More preferably, such as Figure 2 As shown, the brake caliper 100 also includes a protective cover 160 and a mounting bolt 170. One end of the guide pin 130 abuts against the caliper body bracket 110, and a coaxial connecting through hole is provided on the guide pin 130. The mounting bolt 170 is installed in the connecting through hole of the guide pin 130, and the connecting end of the mounting bolt 170 extends axially to the outside of the guide pin 130 and is threaded into the connecting hole 111 of the caliper body bracket 110. The nut end of the mounting bolt 170 abuts against the guide pin 130, that is, the nut end of the mounting bolt 170 abuts against the step in the connecting through hole.

[0046] The protective cover 160 is installed on the periphery of the other end of the guide pin 130, and the protective cover 160 is connected to the brake caliper body 120.

[0047] It should be noted that, in this application, the axial direction refers to... Figure 6 The axial direction of the brake disc 200, the radial direction refers to... Figure 6 The radial direction of the brake disc 200 and the circumferential direction refer to... Figure 6 The circumferential direction of the central brake disc 200.

[0048] Specific embodiment 2, such as Figure 1 , Figure 2 , Figure 4 and Figure 6As shown, a brake caliper 100 includes: a caliper bracket 110, a brake caliper body 120, a guide pin 130, and a dust cover 140.

[0049] Two first guide holes 121 are provided on the brake caliper body 120, and the two first guide holes 121 are located at the two ends of the brake caliper body 120 respectively.

[0050] There are two guide pins 130, and the two guide pins 130 are inserted one-to-one into the two first guide holes 121. One end of the guide pin 130 extends axially to the outside of the brake caliper body 120 and is connected to the caliper body bracket 110.

[0051] There are two dust covers 140, which are fitted one-to-one on the two guide pins 130. The dust covers 140 are located between the two ends of the brake caliper body 120 and the two ends of the caliper body bracket 110. One end of the dust cover 140 is connected to the brake caliper body 120, and the other end of the dust cover 140 is connected to the caliper body bracket 110.

[0052] A protective body 150 is provided on the brake caliper body 120. The axial position of the protective body 150 is directly opposite to the axial position of the dust cover 140. That is, in the radial direction, the protective body 150 and the dust cover 140 are spaced apart. In the axial direction, the position of the protective body 150 is the same as that of the dust cover 140. When the brake caliper 100 is installed on both sides of the brake disc 200, the distance from the protective body 150 to the axis of the brake disc is greater than the distance from the dust cover 140 to the axis of the brake disc.

[0053] Preferred, such as Figure 4 As shown, the protective body 150 is configured as an arc-shaped plate 152 integrally formed on the end of the brake caliper body 120. The arc-shaped plate 152 is located on one side of the dust cover 140, and the radial distance from the arc-shaped plate 152 to the brake disc axis is greater than the radial distance from the dust cover 140 to the brake disc axis. That is, in the radial direction of the brake disc 200, the dust cover 140 is located between the arc-shaped plate 152 and the brake disc axis. This allows ice and snow that are stuck to the rim 300 during vehicle operation to first contact the outer end of the arc-shaped plate 152 when the wheel rotates. Through the friction between the arc-shaped plate 152 and the ice and snow on the rim 300, the length of the ice and snow on the rim 300 is prevented from increasing and colliding or rubbing against the dust cover 140, thereby protecting the dust cover 140 and extending its service life.

[0054] More preferably, when the brake caliper 100 is installed on both sides of the brake disc 200, the arc-shaped plate 152 is located at the end of the brake caliper body 120 where it is in a high position, so that during the manual tire changing process, the rim 300 of the fallen tire first contacts the arc-shaped plate 152, preventing the rim 300 from directly impacting the dust cover 140, thereby protecting the dust cover 140 and extending its service life.

[0055] Specific embodiment 3, such as Figure 2 , Figure 6 and Figure 7 As shown, a brake caliper 100 includes: a caliper bracket 110, a brake caliper body 120, a guide pin 130, and a dust cover 140.

[0056] Two second guide holes are provided on the clamp body support 110, and the two second guide holes are located at the two ends of the clamp body support 110 respectively.

[0057] There are two guide pins 130, and the two guide pins 130 are inserted into the two second guide holes in a one-to-one correspondence. One end of the guide pin 130 extends axially to the outside of the caliper bracket 110 and is fixedly connected to the brake caliper 120.

[0058] There are two dust covers 140, which are fitted one-to-one on the two guide pins 130. The dust covers 140 are located between the two ends of the brake caliper body 120 and the two ends of the caliper body bracket 110. One end of the dust cover 140 is fixedly connected to the brake caliper body 120 or the guide pin 130, and the other end of the dust cover 140 is fixedly connected to the caliper body bracket 110.

[0059] A protective body 150 is provided on the brake caliper body 120. The axial position of the protective body 150 is directly opposite to the axial position of the dust cover 140. That is, in the radial direction, the protective body 150 and the dust cover 140 are spaced apart. In the axial direction, the position of the protective body 150 is the same as that of the dust cover 140. When the brake caliper 100 is installed on both sides of the brake disc 200, the distance from the protective body 150 to the axis of the brake disc is greater than the distance from the dust cover 140 to the axis of the brake disc.

[0060] Preferred, such as Figure 7As shown, the protective body 150 is configured as an arc-shaped plate 152 integrally formed on the end of the brake caliper body 120. The arc-shaped plate 152 is located on one side of the dust cover 140, and the radial distance from the arc-shaped plate 152 to the brake disc axis is greater than the radial distance from the dust cover 140 to the brake disc axis. That is, in the radial direction of the brake disc 200, the dust cover 140 is located between the arc-shaped plate 152 and the brake disc axis. This allows ice and snow that are stuck to the rim 300 during vehicle operation to first contact the outer end of the arc-shaped plate 152 when the wheel rotates. Through the friction between the arc-shaped plate 152 and the ice and snow on the rim 300, the length of the ice and snow on the rim 300 is prevented from increasing and colliding or rubbing against the dust cover 140, thereby protecting the dust cover 140 and extending its service life.

[0061] Specific embodiment 4, such as Figure 1 , Figure 2 and Figure 6 As shown, a brake caliper 100 includes: a caliper bracket 110, a brake caliper body 120, a guide pin 130, and a dust cover 140.

[0062] Two first guide holes 121 are provided on the brake caliper body 120, and the two first guide holes 121 are located at the two ends of the brake caliper body 120 respectively.

[0063] There are two guide pins 130, and the two guide pins 130 are inserted one-to-one into the two first guide holes 121. One end of the guide pin 130 extends axially to the outside of the brake caliper body 120 and is connected to the caliper body bracket 110.

[0064] There are two dust covers 140, which are fitted one-to-one on the two guide pins 130. The dust covers 140 are located between the two ends of the brake caliper body 120 and the two ends of the caliper body bracket 110. One end of the dust cover 140 is connected to the brake caliper body 120, and the other end of the dust cover 140 is connected to the caliper body bracket 110.

[0065] A protective body 150 is provided on the caliper bracket 110. The axial position of the protective body 150 is directly opposite to the axial position of the dust cover 140. That is, in the radial direction, the protective body 150 and the dust cover 140 are spaced apart. In the axial direction, the position of the protective body 150 is the same as that of the dust cover 140. When the brake caliper 100 is installed on both sides of the brake disc 200, the distance from the protective body 150 to the axis of the brake disc is greater than the distance from the dust cover 140 to the axis of the brake disc.

[0066] Preferred, such as Figure 2 and Figure 6As shown, the protective body 150 is configured as an arc-shaped plate 152 integrally formed at the end of the caliper bracket 110. The arc-shaped plate 152 is located on one side of the dust cover 140, and the radial distance from the arc-shaped plate 152 to the brake disc axis is greater than the radial distance from the dust cover 140 to the brake disc axis. That is, in the radial direction of the brake disc 200, the dust cover 140 is located between the arc-shaped plate 152 and the brake disc axis. This allows the ice and snow that are stuck to the rim 300 during vehicle operation to first contact the outer end of the arc-shaped plate 152 when the wheel rotates. Through the friction between the arc-shaped plate 152 and the ice and snow on the rim 300, the length of the ice and snow on the rim 300 is prevented from increasing and colliding or rubbing against the dust cover 140, thereby protecting the dust cover 140 and extending its service life.

[0067] More preferably, such as Figure 6 As shown, when the brake caliper 100 is installed on both sides of the brake disc 200, the arc-shaped plate 152 is located at the end of the brake caliper body 120 where it is in a high position. This allows the rim 300 of the fallen tire to contact the arc-shaped plate 152 first during manual tire changing, preventing the rim 300 from directly impacting the dust cover 140. This protects the dust cover 140 and extends its service life.

[0068] Further optimized, such as Figure 2 As shown, the brake caliper 100 also includes a protective cover 160 and a mounting bolt 170. One end of the guide pin 130 abuts against the caliper body bracket 110, and a coaxial connecting through hole is provided on the guide pin 130. The mounting bolt 170 is installed in the connecting through hole of the guide pin 130, and the connecting end of the mounting bolt 170 extends axially to the outside of the guide pin 130 and is threadedly connected to the connecting hole of the caliper body bracket 110. The nut end of the mounting bolt 170 abuts against the guide pin 130, that is, the nut end of the mounting bolt 170 abuts against the step in the connecting through hole.

[0069] The protective cover 160 is installed on the periphery of the other end of the guide pin 130, and the protective cover 160 is connected to the brake caliper body 120.

[0070] Specific embodiment 5, such as Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, a brake caliper 100 includes: a caliper bracket 110, a brake caliper body 120, a guide pin 130, and a dust cover 140.

[0071] Two first guide holes 121 are provided on the brake caliper body 120, and the two first guide holes 121 are located at the two ends of the brake caliper body 120 respectively.

[0072] There are two guide pins 130, and the two guide pins 130 are inserted one-to-one into the two first guide holes 121. One end of the guide pin 130 extends axially to the outside of the brake caliper body 120 and is connected to the caliper body bracket 110.

[0073] There are two dust covers 140, which are fitted one-to-one on the two guide pins 130. The dust covers 140 are located between the two ends of the brake caliper body 120 and the two ends of the caliper body bracket 110. One end of the dust cover 140 is connected to the brake caliper body 120, and the other end of the dust cover 140 is connected to the caliper body bracket 110.

[0074] A protective body 150 is provided on the caliper bracket 110. The axial position of the protective body 150 is directly opposite to the axial position of the dust cover 140. That is, the protective body 150 and the dust cover 140 are spaced apart in the radial or circumferential direction. In the axial direction, the position of the protective body 150 is the same as that of the dust cover 140. When the brake caliper 100 is installed on both sides of the brake disc 200, the distance from the protective body 150 to the axis of the brake disc is greater than the distance from the dust cover 140 to the axis of the brake disc.

[0075] Preferred, such as Figure 5 As shown, the protective body 150 is configured as a protective post 153 integrally formed at the end of the clamp bracket 110. The protective post 153 is located on one side of the dust cover 140, and the radial distance from the arc plate 152 to the brake disc axis is greater than the radial distance from the dust cover 140 to the brake disc axis. This is so that when the vehicle is in motion, the ice and snow that are stuck to the rim 300 first come into contact with the outer end of the protective post 153 as the wheel rotates. Through the friction between the protective post 153 and the ice and snow on the rim 300, the length of the ice and snow on the rim 300 is prevented from increasing and colliding or rubbing against the dust cover 140, thereby protecting the dust cover 140 and extending its service life.
