Description

Technical Field

[0001] The utility model belongs to the field of vehicle structures, and more specifically, relates to a brake caliper assembly, a brake module and a vehicle. Background Art

[0002] At present, during the vehicle braking process, the driving part on the caliper body can push the friction plate connected thereto towards the brake disc. The friction plate cooperating with the claw on the caliper body can generate a frictional torque when the brake disc is clamped between the two friction plates. The frictional torque causes the rotating speed of the brake disc to decrease or stop, thereby realizing the braking of the vehicle.

[0003] However, due to the short length of the existing claws and the small contact area between the claws and the friction plates on the claws, with the gradual increase of the driving force of the driving part, the caliper body will produce a certain amount of rigid deformation. After the deformation amount of the caliper body increases, the two friction plates will also deflect during the braking process, resulting in uneven wear of the two friction plates, so that the phenomenon of unstable braking occurs. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a brake caliper assembly, a brake module and a vehicle for the deficiencies of the existing technology, so as to solve the problems proposed in the above background art that due to the short length of the existing claws and the small contact area between the claws and the friction plates on the claws, with the gradual increase of the driving force of the driving part, the caliper body will produce a certain amount of rigid deformation. After the deformation amount of the caliper body increases, the two friction plates will also deflect during the braking process, resulting in uneven wear of the two friction plates, so that the phenomenon of unstable braking occurs.

[0005] In order to achieve the above purpose, the utility model provides a brake caliper assembly, and the structure includes:

[0006] A caliper body, at least one claw is bent and extended at one end of the caliper body;

[0007] An extension part is arranged at the outer end of at least one of the claws, and the extension part makes the length of the claw longer.

[0008] Preferably, the structure further includes at least one driving part, and the driving part is connected to the other end of the caliper body;

[0009] Two friction plates, the two friction plates are respectively connected to the inner bent wall of the claw and the driving end of the driving part, the two friction plates are arranged oppositely, and the length of the claw is at least greater than 2 / 3 of the height of the friction plate.

[0010] Preferably, the structure further includes a brake caliper bracket, which includes a mounting bracket and a cross beam. The mounting bracket is in an "n" shape. The two ends of the mounting bracket in the "n" shape are bent and extended and integrally formed and connected to the two ends of the cross beam respectively. The mounting bracket in the "n" shape is sleeved on the driving part and fixedly connected to the caliper body. The cross beam is arranged on the side of the claw away from the driving part.

[0011] Preferably, the extension part is flat, and the flat extension part extends between the friction plate on the inner bent wall and the cross beam.

[0012] Preferably, the driving part includes two driving hydraulic cylinders, and the two driving hydraulic cylinders are arranged side by side.

[0013] Preferably, the number of the claws is three, and the three claws are arranged side by side.

The beneficial effects are as follows: An extension part is arranged at the outer end of at least one of the claws of the structure. The extension part makes the length of the claw longer. Furthermore, the contact force point between the claw and the friction plate changes, so that the force position of the friction plate is at its geometric center, and the deflection of the two friction plates will be reduced. While the claw is lengthened, the contact area between the claw and the friction plate on the claw is also increased, so that the outer edge of the friction plate on the claw can form a more perfect fit with the brake disc, enabling the two friction plates to be in uniform contact with the brake disc, realizing uniform wear of the two friction plates. When the claw is lengthened and the contact area is increased, the stress on the caliper body becomes smaller and the stiffness increases.

[0031] The preferred embodiments of the present utility model will be described in more detail below. Although the preferred embodiments of the present utility model are described below, it should be understood that the present utility model can be implemented in various forms and should not be limited by the embodiments set forth herein. On the contrary, these embodiments are provided to make the present utility model more thorough and complete, and to fully convey the scope of the present utility model to those skilled in the art.

[0032] As Figure 1 , Figure 2 and Figure 5 shown, the present utility model provides a brake caliper assembly, and the structure includes:

[0033] The clamp body main body 1, and at least one claw 2 is bent and extended from one end of the clamp body main body 1;

[0034] An extension portion 10 is provided at the outer end of at least one of the claws 2, and the extension portion 10 lengthens the length of the claw 2.

[0035] Specifically, to solve the problems that the existing claws are short, the contact area between the claws and the friction plates on the claws is small, and as the driving force of the driving part gradually increases, the clamp body will produce a certain amount of rigid deformation. After the deformation amount of the clamp body increases, the two friction plates will also deflect during the braking process, resulting in uneven wear of the two friction plates, and even causing the problem of unstable braking. The present utility model provides a brake caliper assembly. An extension portion 10 is provided at the outer end of at least one of the claws 2 of this structure, and the extension portion 10 lengthens the length of the claw 2. Furthermore, the contact force application point between the claw 2 and the friction plate 4 changes, making the force application position of the friction plate 4 at its geometric center. The deflection of the two friction plates 4 will be reduced. While the claw 2 is lengthened, the contact area between it and the friction plate 4 on the claw 2 is also increased, enabling the outer edge of the friction plate 4 on the claw 2 to form a more perfect fit with the brake disc 9, making the two friction plates 4 and the brake disc 9 achieve uniform contact, and realizing uniform wear of the two friction plates 4. When the claw 2 is lengthened to increase the contact area, the stress on the clamp body main body 1 becomes smaller and the stiffness increases. Finally, the overall stiffness of the brake caliper assembly is also improved, and more stable braking can be achieved.

[0036] Such as Figure 2 and Figure 4 As shown, preferably, this structure further includes at least one driving part 3, and the driving part 3 is connected to the other end of the clamp body main body 1;

[0037] Two friction plates 4, the two friction plates 4 are respectively connected to the inner bent wall of the claw 2 and the driving end of the driving part 3, the two friction plates 4 are arranged oppositely, and the length of the claw 2 is at least greater than 2 / 3 of the height of the friction plate 4.

[0038] Specifically, during the braking process, the driving part 3 can push the friction plate 4 connected to it towards the brake disc 9. In cooperation with the friction plate 4 on the inner bent wall, it can make the brake disc 9 generate a frictional torque under the clamping of the two friction plates 4, and the frictional torque causes the rotating speed of the rotating brake disc 9 to decrease or stop, thereby realizing the braking of the vehicle;

[0039] The ideal length of the claw 2 is preferably to cover the entire height of the friction plate 4 on the entire inner bent wall. When space is limited, the length of the claw 2 is at least greater than 2 / 3 of the height of the friction plate 4.

[0040] Such as Figure 1 and Figure 3As shown, preferably, the structure further includes a brake caliper bracket 5, which includes a mounting bracket 6 and a cross beam 7. The mounting bracket 6 is in an n shape. The two ends of the n-shaped mounting bracket 6 are bent and extended and integrally formed and connected to the two ends of the cross beam 7 respectively. The n-shaped mounting bracket 6 is sleeved on the driving part 3 and fixedly connected to the caliper body 1. The cross beam 7 is arranged on the side of the hook 2 away from the driving part 3.

[0041] Specifically, the mounting bracket 6 is provided with connection holes for fixedly connecting to the steering knuckle 8 through bolts.

[0042] Preferably, the extension part 10 is flat, and the flat extension part 10 extends between the friction plate 4 on the inner bending wall and the cross beam 7.

[0043] Specifically, on the premise of meeting the strength requirements, the extension part 10 is made flat. Furthermore, without changing the structure of the original cross beam 7, the extension part 10 can extend between the friction plate 4 on the inner bending wall and the cross beam 7. Furthermore, the modification amount on the basis of the original scheme is minimized, saving costs.

[0044] Preferably, the driving part 3 includes two driving hydraulic cylinders, and the two driving hydraulic cylinders are arranged side by side.

[0045] Specifically, when the deflection of the friction plate 4 decreases, the required liquid volume of the hydraulic cylinder will become smaller and stable, improving the working performance of the hydraulic cylinder.

[0046] Preferably, the number of the hooks 3 is three, and the three hooks 3 are arranged side by side.

[0047] Specifically, the three hooks 3 are applicable to the brake caliper assembly.

[0048] Preferably, an extension part 10 is arranged at the outer end of the middle hook 3.

[0049] Specifically, the force application position of the friction plate 4 on the inner bending wall is more easily located at its geometric center.

[0050] Preferably, the caliper body 1 is an aluminum caliper body.

[0051] As Figure 6 shown, a braking module, which includes:

[0052] A brake caliper assembly, with the caliper body 1 fixedly connected to the steering knuckle 8;

[0053] A brake disc 9, which is rotatably connected to the steering knuckle 8 and is arranged between the two friction plates 4.

[0054] A vehicle, which includes the brake caliper assembly.

[0055] In summary, when the braking module provided by the present utility model is implemented on an automobile, since the extension portion 10 lengthens the length of the claw 2, furthermore, the contact force application point between the claw 2 and the friction plate 4 changes, making the force application position of the friction plate 4 at its geometric center, the deflection of the two friction plates 4 will be reduced, and the required liquid volume of the hydraulic cylinder will become smaller and stable; the ideal length of the claw 2 is preferably to cover the entire height of the friction plate 4 on the entire inner bent wall. When the space is limited, the length of the claw 2 is at least greater than 2 / 3 of the height of the friction plate 4; while the claw 2 is lengthened, the contact area between the claw 2 and the friction plate 4 on the claw 2 is also increased, enabling the outer edge of the friction plate 4 on the claw 2 to form a more perfect fit with the brake disc 9, so that the two friction plates 4 and the brake disc 9 achieve uniform contact, and the wear of the two friction plates 4 is uniform; when the claw 2 is lengthened to increase the contact area, the stress on the caliper body 1 becomes smaller and the stiffness increases. At the same time, in order not to change the structure of the brake caliper bracket 5, on the premise of meeting the strength requirements, the extension portion 10 is made flat, and the extension portion 10 can be arranged between the friction plate 4 on the inner bent wall and the cross beam 7. Furthermore, the modification amount based on the original scheme is minimized, saving costs. This design effectively utilizes the layout space of the brake caliper assembly and fully lengthens the length of the middle claw 2 of the brake caliper assembly to meet the requirements of the initial design goal.

[0056] The embodiments of the present utility model have been described above. The above description is exemplary and not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art without departing from the scope and spirit of the described embodiments.
