TECHNICAL FIELD

[0001] The utility model relates to brake component technical field, especially in brake caliper protection structure, simultaneously, the utility model relates to a kind of brake caliper assembly with the brake caliper protection structure, and vehicle with the brake caliper assembly. BACKGROUND

[0002] The existing brake caliper assembly is composed of three main components: actuator, caliper body and caliper frame. Among them, the threaded holes are arranged at the left and right side lugs of the caliper body, and the corresponding threaded grooves are arranged at the corresponding positions of the caliper frame. The two are reliably connected by bolts, so that the caliper body is firmly fixed on the caliper frame. In addition, the threaded holes are arranged in the middle of the boss reinforcing ribs at the left and right ends of the actuator, and the corresponding threaded grooves are arranged at the corresponding positions of the caliper body. The actuator and the caliper body are tightly connected by bolt fastening.

[0003] However, the pin dust cover of the existing brake caliper is directly exposed to the external environment, and is easily damaged and lost due to the erosion of natural factors such as sunlight, rain, snow and the like for a long time. In addition, when driving in the rain or contacting road deicing agents and other chemicals, the metal parts of the brake caliper are prone to corrosion, which not only affects the performance of the parts themselves, but also accelerates the aging of the pin dust cover, significantly shortening its service life. SUMMARY

[0004] Therefore, the utility model aims to provide a brake protection structure to protect the dust cover and prolong its service life.

[0005] To achieve the above-mentioned purpose, the technical scheme of the utility model is as follows:

[0006] A brake caliper protection structure includes a guard plate, which is arranged at the connecting assembly of the caliper body and the caliper frame of the brake caliper.

[0007] The guard plate has a top portion and a side portion. The top portion is arranged on the top of the dust cover of the connecting assembly, and the side portion is arranged on the outside of the dust cover.

[0008] Further, the guard plate is connected to the caliper body through the top portion.

[0009] Further, the caliper body includes a caliper body and a lug protruding outwardly from the caliper body. The caliper body is connected to the caliper frame through the lug.

[0010] The top portion is screwed on the lug.

[0011] Further, the top portion has an outwardly protruding portion, which protrudes outwardly to one side of the side portion along the connecting direction of the connecting assembly.

[0012] The top portion is connected to the lug by the outer protrusion.

[0013] Further, the brake caliper protection structure further comprises a shield covering the actuator of the brake caliper.

[0014] The shield comprises an annular portion surrounding the actuator and an end portion disposed outside the actuator.

[0015] Further, the actuator comprises an actuator body and a boss protruding outward from the actuator body.

[0016] Corresponding to the boss, the annular portion is provided with a connecting block protruding radially outward, and an external fastener connects the connecting block, the boss and the caliper body together.

[0017] Further, a reinforcing rib is provided between the actuator body and the boss.

[0018] The annular portion is provided with a protrusion protruding radially outward, and the protrusion covers the reinforcing rib.

[0019] Further, the annular portion is provided with a protrusion protruding radially outward, and the protrusion covers the reinforcing rib.

[0020] Compared with the prior art, the utility model has the following advantages:

[0021] The brake caliper protection structure comprises a shield plate, a top portion, a lug and a connecting assembly. The shield plate is connected to the lug by the top portion. The connecting assembly is connected to the lug and the caliper body. The shield plate is provided on the connecting assembly. The shield plate can reduce the direct exposure of the dust cover, prevent damage due to external impact, prevent water from directly impacting the dust cover in rainy weather or after passing through a waterlogged section, reduce water infiltration, reduce the phenomenon of metal parts rusting and corroding the dust cover, have a good protective effect on the dust cover, prolong the service life of the dust cover, improve the durability of the dust cover, and reduce the maintenance requirements.

[0022] In addition, the shield plate is connected to the caliper body by the top portion, which can fully utilize the rigidity of the caliper body to ensure that the shield plate remains stable during vehicle driving, avoids loosening or falling off due to vibration or impact, and can directly transmit external impact force to the caliper body to avoid the dust cover or the connecting assembly bearing additional stress, thereby prolonging the service life of the dust cover. The lug is a connecting component of the caliper body and the caliper frame, which usually has high structural strength and rigidity. The top portion of the shield plate is screwed to the lug, which can fully utilize the load capacity of the lug to ensure that the shield plate remains stable during vehicle driving and avoids loosening due to vibration or impact. In addition, the screwing method is convenient for disassembly and replacement, which reduces the complexity of production and maintenance.

[0023] Secondly, by setting the outwardly convex part outwardly convex to the side portion side in the top portion, the top portion is facilitated to be connected with the lug, and the external force received by the guard plate is also facilitated to be transmitted to the caliper body. By setting the guard shield on the actuator of the brake caliper, and by making the annular portion of the guard shield surround the actuator, and by making the end portion block the outside of the actuator, a full-coverage protective layer is formed, which can block the flame and high temperature, and protect the actuator from the invasion of external fire, high temperature, dust, moisture and other adverse factors, so as to ensure the stable operation of the equipment, prolong the service life of the equipment, and reduce the frequency of maintenance and replacement.

[0024] Furthermore, by setting the connecting block corresponding to the boss of the actuator on the annular portion, and by connecting the connecting block, the boss and the caliper body together through external fasteners, the guard shield, the actuator and the caliper body can form a close overall structure, which is beneficial to improve the overall rigidity and stability of the brake caliper; at the same time, the external impact force can be effectively dispersed, the relative displacement of each part can be reduced, and the risk of loosening or deformation can be reduced.

[0025] In addition, by setting the protruding part outside the reinforcing rib on the annular portion, the invasion of foreign matter to the reinforcing rib can be effectively prevented, so that the reinforcing effect of the reinforcing rib on the actuator body and the boss can be ensured, and the structural strength of the brake caliper as a whole can be ensured. By interference-fitting the annular portion on the actuator body, the radial displacement of the guard shield can be prevented, the setting stability of the guard shield can be improved, and at the same time, the external impurities can be effectively prevented from entering the gap between the annular portion and the actuator, so that the external impurities can be better isolated, and the performance degradation of the actuator caused by corrosion and pollution can be effectively prevented.

[0026] Another purpose of the utility model is to provide a brake caliper assembly comprising a brake caliper and the brake caliper protection structure as described above arranged on the brake caliper.

[0027] The brake caliper assembly has the advantages that the external invasion on the dust cover and the actuator can be reduced by arranging the brake caliper protection structure as described above, so that the service life of the dust cover and the actuator can be prolonged, and the frequency of maintenance and replacement of the brake caliper assembly can be reduced, and the cost can be saved.

[0049] Embodiment one

[0050] This embodiment relates to a brake caliper protection structure, including the guard plate 4, the guard plate 4 is arranged at the connecting assembly of the caliper body 1 and the caliper frame 2 of brake caliper. Wherein, the guard plate 4 has top portion 401 and side portion 402, top portion 401 is blocked at the top of the dust cover 6 of connecting assembly, and side portion 402 is blocked at the outside of dust cover 6.

[0051] The brake caliper protection structure of this embodiment, by setting the guard plate 4 at the connecting assembly of the caliper body 1 and the caliper frame 2 of brake caliper, can reduce the direct exposure of dust cover 6, prevent it from being damaged due to external impact, and when it rains or passes through the waterlogged road section, the guard plate 4 can prevent water from directly impacting the dust cover 6, reduce water infiltration, reduce the phenomenon of metal parts rusting and corroding the dust cover 6, can have good protection effect to the dust cover 6, and prolong its service life to avoid metal parts rusting, improve durability. In addition, the guard plate 4 can also better block dust and sand, reduce the possibility of entering the connecting assembly, thereby prolonging the service life of the connecting assembly and reducing the maintenance requirement.

[0052] Based on the overall introduction as above, one exemplary structure of the brake caliper protection structure of the embodiment is referred to Figures 1 to 3 The structure of brake caliper is the same as prior art, and as Figure 4As shown in the drawings, the brake caliper assembly mainly comprises a caliper body 1, a caliper bracket 2 and an actuator 3. The connecting assembly of the caliper body 1 and the caliper bracket 2 mainly comprises a guide pin arranged on the caliper bracket 2 and a mounting bolt penetrating through the caliper body 1. The head of the guide pin is internally threaded, and the mounting bolt is connected with the guide pin by screwing after penetrating through the caliper body 1. The dust cover 6 is arranged on the outside of the guide pin to prevent external dust and sundries from entering the connecting assembly.

[0053] In addition, as a preferred embodiment, as shown in Figure 5 and Figure 6 shown in the drawings, the guard plate 4 of the present embodiment is L-shaped, and the top portion 401 and the side portion 402 are both flat and vertically arranged. It should be noted that, in addition to being perpendicular to each other, the top portion 401 and the side portion 402 can also be arranged at an acute angle or an obtuse angle. In addition, in addition to being flat, the top portion 401 and the side portion 402 can also be arc-shaped and smoothly connected. That is, at this time, the guard plate 4 is generally arc-shaped, as long as it can protect the top and side of the dust cover 6. In addition, the top of the present embodiment is based on the orientation shown in Figure 2 , the side is the side close to the external environment of the brake caliper assembly as a whole.

[0054] Here, as a preferred embodiment, in combination with Figures 1 to 3 shown in the drawings, the guard plate 4 of the present embodiment is connected to the caliper body 1 through the top portion 401. In this way, the rigidity of the caliper body 1 can be fully utilized to ensure that the guard plate 4 remains stable during vehicle driving and avoids loosening or falling off due to vibration or impact. At the same time, external impact forces can be directly transmitted to the caliper body 1, avoiding additional stress on the dust cover 6 or the connecting assembly, thereby prolonging its service life. Moreover, this connection method will not interfere with other functional components of the brake caliper, ensuring the normal operation of the brake system.

[0055] Specifically, as shown in Figures 1 to 3 , the caliper body 1 comprises a caliper body and a lug 101 protruding outward from the caliper body, and the caliper body 1 is connected to the caliper bracket 2 through the lug 101, and the top portion 401 is screwed onto the lug 101. In addition, the lug 101 is usually two lugs arranged on opposite sides of the caliper body, and correspondingly, the connecting assembly and the guard plate 4 are both two corresponding to the lug 101.

[0056] The support lug 101 is a connecting component of the caliper body 1 and the caliper bracket 2, and generally has high structural strength and rigidity. The top portion 401 of the guard plate 4 is screwed on the support lug 101, so that the load bearing capacity of the support lug 101 can be fully utilized, and the guard plate 4 can be kept stable during vehicle driving, avoiding loosening due to vibration or impact. At the same time, since the guard plate 4 is fixed on the support lug 101 by screwing, when the dust cover 6 needs to be replaced or maintained, the guard plate 4 can be removed alone without disassembling the entire brake caliper structure, reducing the maintenance difficulty. Moreover, the screwing method is also convenient for adjusting the position of the guard plate 4 or replacing the damaged guard plate 4, improving the maintenance efficiency.

[0057] At this time, as shown in Figures 1 to 3 For the convenience of connecting the top portion 401 with the support lug 101, the top portion 401 has an outward protruding portion which protrudes outward to one side of the side portion 402 along the connecting direction of the connecting component, and the top portion 401 is connected with the support lug 101 by screwing through the outward protruding portion. The connecting direction of the connecting component is the axial direction of the mounting bolt, and the support lug 101 extends in a direction approximately perpendicular to the connecting component.

[0058] In this embodiment, by providing the outward protruding portion which protrudes outward to one side of the side portion 402 on the top portion 401, the connection between the top portion 401 and the support lug 101 is facilitated, and the external force received by the guard plate 4 can also be transmitted to the caliper body 1. In addition, the design of the outward protruding portion enables the top portion 401 of the guard plate 4 to extend outward and connect with the support lug 101 without increasing the overall volume, and makes full use of the space around the brake caliper. At the same time, the design of the outward protruding portion does not require additional complex components, and better protection effect can be achieved through simple structural improvement, which can reduce production cost.

[0059] As a further embodiment, in combination with Figures 2 to 6 As shown in, the width of the outward protruding portion gradually decreases in the direction away from the side portion 402. This design facilitates the external impact received by the guard plate 4 to be well transmitted to the caliper body 1 for dispersion, and also facilitates the positioning and alignment of the guard plate 4 during installation. In addition, the design of the outward protruding portion with gradually decreasing width makes the appearance of the guard plate 4 more smooth and beautiful, and also can reduce the amount of material used while ensuring the structural strength.

[0060] In addition, as a preferred embodiment, in combination with Figure 5 and Figure 6As shown in FIG. 4, a protruding block 403 is arranged at the corner of the outer protruding part 402 and protrudes towards the side part 402. A connecting hole is arranged on the protruding block 403 for connecting with the supporting lug 101. When installed, the protruding block 403 abuts against the supporting lug 101 and is screwed on the supporting lug 101 through the connecting hole. In this embodiment, the protruding block 403 abuts against the supporting lug 101 to form a gap between the top part 401 and the dust cover, which can effectively prevent the damage of the dust cover 6 caused by the vibration of the guard plate 4 under external force impact.

[0061] With reference to the foregoing Figures 1 to 3 As a further embodiment, the brake caliper protection structure of this embodiment further comprises a cover 5 arranged on the actuator 3 of the brake caliper. The cover 5 comprises an annular part 501 arranged around the actuator 3 and an end part 502 arranged outside the actuator 3. In this embodiment, the cover 5 arranged on the actuator 3 of the brake caliper is provided, and the annular part 501 of the cover 5 is arranged around the actuator 3, and the end part 502 is arranged outside the actuator 3, forming a comprehensive protection layer, which can block the flame and high temperature, protect the actuator 3 from external fire, high temperature, dust, moisture and other adverse factors, thereby ensuring the stable operation of the equipment, prolonging the service life of the equipment, and reducing the frequency of maintenance and replacement.

[0062] In combination with Figure 2 , Figure 3 and Figure 7 and Figure 8 As shown in FIG. 5, the actuator 3 of this embodiment comprises an actuator body and a protrusion 301 protruding outward from the actuator body. Corresponding to the protrusion 301, the annular part 501 is provided with a connecting block 503 protruding outward along the radial direction of the annular part 501, and the external fastener connects the connecting block 503, the protrusion 301 and the caliper body 1 together. The structure of the actuator body can refer to the prior art, and generally, two protrusions 301 are arranged on the two opposite sides of the actuator body to improve the connection firmness between the actuator 3 and the caliper body 1.

[0063] In this embodiment, the connecting block 503 of the cover 5, the protrusion 301 of the actuator 3 and the caliper body 1 are connected together by the external fastener, so that the cover 5, the actuator 3 and the caliper body 1 form a compact overall structure, which significantly improves the overall rigidity and stability of the brake caliper. This connection method can effectively disperse external impact force and vibration energy, reduce the relative displacement of each part, and reduce the risk of loosening or deformation. In addition, the cover 5 is an independent part connected by the external fastener, which is convenient for disassembly and replacement. The external fastener can be a bolt, and at this time, a connecting groove with a threaded hole can be arranged on the caliper body 1, a through hole can be arranged on the protrusion 301, and a via hole for the bolt to pass through can be arranged on the connecting block 503.

[0064] In addition, as a further embodiment, the annular portion 501 is shaped to the actuator body and is fitted on the actuator body in an interference fit. In this way, the structural stability between the shroud 5 and the actuator 3 can be improved, and the shroud 5 can be kept stable during vehicle driving. In addition, the interference fit can effectively prevent dust, sand, rainwater and other pollutants from entering the gap between the shroud 5 and the actuator 3, and can further protect the actuator 3 from external environment, thereby prolonging the service life of the actuator 3. Moreover, the interference fit forms a seamless connection between the shroud 5 and the actuator body, and the overall appearance is more compact and beautiful, which is beneficial to improve the integration and aesthetics of the product
