Description

Technical Field

[0001] This application relates to the field of automotive braking technology, and in particular to a caliper body assembly, caliper, and brake. Background Technology

[0002] As a key component of automotive electronic brake systems, the caliper drives a piston to press the friction pads against the brake disc, providing braking and parking functions. The caliper includes a piston, a drive linkage assembly (comprising a screw and a nut fitted onto the screw) housed within the piston and capable of floating relative to it, an actuator, and the caliper body. The actuator drives the screw and nut mounted in the caliper body, which in turn pushes the piston to engage the friction pads mounted on the caliper, gripping the brake disc and thus achieving the parking function.

[0003] Currently, caliper bodies are usually formed by one-piece casting of metal parts, but such caliper bodies, while having a low weight, are difficult to have strong structural rigidity. Utility Model Content

[0004] This application provides a caliper body assembly, a caliper, and a brake, which improves the rigidity of the caliper body assembly while reducing its weight, thereby at least partially solving the above-mentioned technical problems.

[0005] To achieve the above objectives, according to a first aspect of this application, a caliper body assembly is provided, comprising:

[0006] The clamp body has a mounting hole and a mounting groove. Along the axial direction of the mounting hole, the mounting groove is located on one side of the mounting hole and communicates with the mounting hole.

[0007] An insert is embedded in the clamp body, the insert comprising a structural member with a density less than that of the clamp body, the insert being configured to enhance the structural rigidity of the clamp body.

[0008] Optionally, the insert is fitted into the wall of the mounting groove; and / or,

[0009] The embedded component includes:

[0010] A metal plate, the shape of which is adapted to the wall of the mounting groove and embedded in the wall of the mounting groove.

[0011] Optionally, along the axial direction of the mounting hole, the metal plate extends from the side of the mounting groove near the mounting hole to the side away from the mounting hole.

[0012] Optionally, the metal plate comprises:

[0013] The plate body includes a first surface and a second surface along the thickness direction of the plate body;

[0014] A protruding structure, wherein the protruding structure protrudes from at least one of the first surface and the second surface.

[0015] Optionally, the protrusion structure includes a plurality of protrusions, which are arranged in multiple rows and columns; and / or,

[0016] Along the first direction, a first clearance groove is provided on the side of the plate body near the bottom of the mounting groove, and the first clearance groove is connected to the mounting groove.

[0017] Optionally, a groove is formed between two adjacent rows and / or two adjacent columns of the protrusions, the groove having an inner wall surface close to the protrusion, and the projected outer contour of the inner wall surface is a straight line along the thickness direction of the plate body.

[0022] The caliper body assembly of this application embodiment includes a caliper body and an insert. The insert is embedded in the caliper body and includes a structural member with a density lower than that of the caliper body. The insert is configured to enhance the structural rigidity of the caliper body. Therefore, since the density of the caliper body is lower than that of the insert, the weight of the caliper body will not be excessive. By embedding an insert that enhances its structural rigidity within a relatively lightweight caliper body, the rigidity of the caliper body assembly is improved while maintaining a low weight.

[0033] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the protection scope of this application.

[0034] Currently, common caliper bodies are either made of pure aluminum or pure iron. Pure aluminum caliper bodies have low density and light weight, but are large in size, have weak rigidity, and are expensive. Cast iron caliper bodies, on the other hand, have high density, heavy weight, small size, good rigidity, and are inexpensive. It is clear that such caliper bodies struggle to balance low weight and high rigidity.

[0035] To address the aforementioned problems, the first embodiment of this utility model provides a caliper body assembly, please refer to [link to relevant documentation]. Figures 1 to 4 The caliper body assembly includes a caliper body 10 and an insert 20. The caliper body 10 has a mounting hole 11 and a mounting groove 12. Along the axial direction of the mounting hole 11, the mounting groove 12 is located on one side of the mounting hole 11 and communicates with it. A transmission connection kit can be installed in the mounting hole 11, and the piston can move at least partially into the mounting groove 12. Along the axial direction of the mounting hole 11, friction plates can be provided on the side of the mounting groove 12 away from the mounting hole 11 and on the piston. The transmission connection kit can push the piston to cause the friction plates to grip the brake disc, thereby achieving a parking function.

[0036] The insert 20 is embedded within the caliper body 10. The insert 20 includes structural components with a density lower than that of the caliper body 10, and is configured to enhance the structural rigidity of the caliper body 10. Because the caliper body 10 has a lower density than the insert 20, its weight will be lighter. Since the insert 20 enhances the structural rigidity of the caliper body 10, it achieves both light weight and high structural rigidity. This prevents deformation and damage during braking and parking, thereby extending the service life of the caliper assembly.

[0037] As can be seen, the caliper body assembly of this application embodiment includes a caliper body 10 and an insert 20. The insert 20 is embedded within the caliper body 10 and includes structural components with a density lower than that of the caliper body 10. The insert 20 is configured to enhance the structural rigidity of the caliper body 10. Therefore, since the density of the caliper body 10 is lower than that of the insert 20, the weight of the caliper body 10 will not be excessive. By embedding the insert 20, which enhances the structural rigidity of the relatively lightweight caliper body 10, the rigidity of the caliper body assembly is improved while maintaining a lower weight.

[0038] During the use of the caliper, considering the stress on the caliper body 10, the mounting groove 12 (i.e., the caliper opening) requires a significant amount of material to ensure rigidity. Other structural components, especially the caliper fixing gear, bearings, force transmission mechanism, and motor, do not require transmitting large forces or high rigidity. Therefore, in this embodiment, the rigidity of the entire caliper body 10 can be ensured simply by embedding the insert 20 within the groove wall of the mounting groove 12. This eliminates the need to embed the insert 20 outside the mounting groove 12, further reducing the weight of the caliper body 10 while simultaneously improving its structural rigidity.

[0039] Among them, such as Figure 2 and Figure 3As shown, the insert 20 in this embodiment may include a metal plate 21. The shape of the metal plate 21 is adapted to the groove wall of the mounting groove 12 and is embedded in the groove wall of the mounting groove 12.

[0040] The metal plate 21 is easy to process. In terms of processing technology, the metal plate 21 can be obtained by stamping or casting. When casting the clamp body 10, the metal plate 21 can be embedded into the clamp body 10.

[0041] Along the axial direction of the mounting hole, the metal plate 21 extends from the side of the mounting groove 12 near the mounting hole 11 to the side away from the mounting hole 11, thereby reinforcing and strengthening the rigidity of the entire mounting groove 12.

[0042] like Figure 4 As shown, the metal plate 21 in this embodiment includes a plate body 211 and a protruding structure 212. Along the thickness direction of the plate body 211, the plate body 211 includes a first surface 2111 and a second surface 2112. The protruding structure 212 protrudes from at least one of the first surface 2111 and the second surface 2112.

[0043] Therefore, in this embodiment, a protruding structure 212 can be provided on at least one of the first surface 2111 and the second surface 2112 of the plate body 211. The protruding structure 212 can increase the bonding area between the metal plate 21 and the clamp body 10, which can make the metal plate 21 and the clamp body 10 bond better, the force transmission more stable, and the fatigue performance better.

[0044] The protrusion structure 212 in this embodiment includes multiple protrusions 120, which are arranged in multiple rows and columns. The multiple rows and columns of protrusions 120 enable the metal plate 21 to fit more stably with the clamp body 10, resulting in better bonding strength.

[0045] Along the first direction (e.g.) Figure 1 (In the direction indicated by the middle arrow X), a first clearance groove 110 is provided on the side of the plate body 211 near the bottom of the mounting groove 12, and the first clearance groove 110 communicates with the mounting groove 12. This not only reduces the overall volume of the plate body 211, thereby further reducing the weight of the caliper body assembly, but also ensures that the plate body 211 does not occupy the mounting space within the mounting groove 12, ensuring that the friction pad can be stably and reliably installed within the mounting groove 12. Furthermore, in this embodiment, the bottom of the first clearance groove 110 can be flush with the bottom of the mounting groove 12, making the overall structure of the caliper body assembly more compact and reliable.

[0046] A groove 201 is formed between two adjacent rows and / or two adjacent rows of protrusions 120. The groove 201 has an inner wall surface near the protrusion 120, and the projected outer contour of the inner wall surface is a straight line along the thickness direction of the plate body 211. That is, the groove 201 formed between two adjacent rows and / or two adjacent rows of protrusions 120 is a straight groove. This type of groove 201 is convenient to process and has low processing difficulty. Of course, in some other embodiments, the groove 201 in this embodiment can also be a curved groove or other irregular groove structure. Here, this embodiment does not make a limitation.

[0047] Along the thickness direction of the plate body 211, the projected outer contour of the protrusion structure 212 on the first surface 2111 coincides with the projected outer contour of the protrusion structure 212 on the second surface 2112. That is, when both the first surface 2111 and the second surface 2112 are provided with protrusion structures 212 composed of multiple protrusions 120, the multiple rows and columns of protrusions 120 on the first surface 2111 and the multiple rows and columns of protrusions 120 on the second surface 2112 are arranged in a one-to-one correspondence, so that the bonding strength between the plate body 211 and the clamp body 10 on opposite sides along its own thickness direction is balanced.

[0048] The metal plate 21 includes at least two pieces, which are spaced apart from each other. The structural rigidity of the clamp body 10 is further improved by the at least two spaced metal plates 21.

[0049] In this embodiment, the clamp body 10 may specifically include an aluminum clamp body, and the metal plate 21 may include an iron plate. By embedding the iron plate in the aluminum clamp body, especially in the groove wall of the mounting groove 12 of the aluminum clamp body, the aluminum clamp body can have a lighter weight while maintaining strong structural rigidity. At the same time, since the unit price of the iron plate is low, the production cost of the aluminum clamp body can also be reduced.

[0050] Along the axial direction of the mounting hole 11, the mounting groove 12 includes a first sidewall 121 away from the mounting hole 11, the first sidewall 121 being provided with a second clearance groove 122, the second clearance groove 122 communicating with the mounting groove 12, along a second direction (e.g. Figure 1 (In the direction indicated by the middle arrow Y), at least one metal plate 21 is located on one side of the second clearance groove 122. Along the second direction, at least another metal plate 21 is located on the other side of the second clearance groove 122. Thus, by embedding at least two metal plates 21 in the groove wall of the mounting groove 12 and by spaced at least two metal plates 21 on opposite sides of the second clearance groove 122, the weight of the clamp body 10 is reduced while ensuring the structural rigidity of the clamp body 10 at the mounting groove 12, so that the clamp body 10 has the structural advantages of both lightweight and high rigidity.

[0051] The protruding structure 212 may be provided on at least two metal plates 21, or it may be provided on only at least one of the metal plates 21. This embodiment is not limited to this.

[0053] The third embodiment of this utility model also provides a brake, which includes the caliper provided in the second embodiment of this application. The brake has all the beneficial effects of the caliper provided in the second embodiment, which will not be repeated here.
