Description

Technical Field

[0001] This utility model relates to the field of brake disc design technology, and in particular to an adaptive floating brake disc. Background Technology

[0002] A brake disc, simply put, is a round plate that rotates when the car is moving. The brake caliper clamps onto the brake disc to generate braking force; when you press the brake pedal, it's the caliper that clamps onto the brake disc to slow down or stop the car. Brake discs offer better braking performance and are easier to maintain than drum brakes.

[0003] Adaptive floating brake discs typically separate the outer friction surface of the brake disc from the inner support, with a special non-rigid structure connecting them in the middle, namely a floating connection. However, when a vehicle brakes for a long time or frequently, the brake disc will generate a lot of heat due to friction, causing the temperature to rise sharply. When the temperature rises to a certain level, the material properties of the brake disc will change, the coefficient of friction will decrease, and thus the braking effect will be weakened.

[0004] Therefore, it is necessary to provide an adaptive floating brake disc to solve the above-mentioned technical problems. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] First Embodiment

[0028] Please refer to the following: Figure 1 and Figure 2 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of an adaptive floating brake disc provided by this utility model; Figure 2 for Figure 1 The diagram shows the connection structure of the connecting assembly and the planetary disk. An adaptive floating brake disc includes: a brake caliper assembly 1, the brake caliper assembly 1 including a caliper body 11, and a connecting plate 12 fixedly connected to the surface of the caliper body 11;

[0029] Connecting component 2, which is disposed on the surface of the connecting plate 12, includes a sun wheel 21 and a first limiting groove 22;

[0030] Planetary assembly 3, which is disposed on the outer surface of the connecting assembly 2, includes a planetary disk 31, a fan blade 32, and a planet carrier 33;

[0031] Brake disc assembly 4 is disposed on the outer surface of planetary disk 31. Brake disc assembly 4 includes disc body 41, second limiting groove 42 and heat dissipation hole 43.

[0032] There are two connecting plates 12, which are fixedly connected to the left and right ends of the caliper body 11 respectively. The function of the connecting component 2 is to connect the transmission. The function of the planetary component 3 is to increase the heat dissipation performance of the brake disc. The function of the brake disc component 4 is to achieve braking by connecting with the brake caliper of the caliper body 11.

[0033] The sun disk 21 is movably connected to the inner surface of the bottom of the first limiting groove 22, and the first limiting groove 22 is formed on the outer surface of the sun disk 21.

[0034] The surface of the sun disk 21 has multiple heat dissipation holes. The first limiting groove 22 is ring-shaped and has teeth arranged in an array on its inner surface. The bottom inner surfaces of the two connecting plates 12 are connected by a rod, and the sun disk 21 is slidably sleeved on the surface of the rod.

[0035] The planetary disk 31 is movably connected inside the first limiting groove 22, the fan blade 32 is fixedly connected inside the planetary disk 31, and the planet carrier 33 is movably connected to the inner surfaces of the planetary disk 31 and the connecting plate 12 at both ends.

[0036] The planetary assembly 3 consists of three planetary disks 31. The outer surfaces of the three planetary disks 31 are all provided with teeth arranged in an array. The teeth mesh with the teeth inside the first limiting groove 22, so that the three planetary disks 31 are circumferentially connected to the surface of the sun disk 21. The interior of each planetary disk 31 is fixedly connected with multiple fan blades 32. The curved surface design of the fan blades 32 and the tilt angle with the rotation axis cause the air pressure on one side of the fan blades 32 to decrease and the air pressure on the other side to increase during rotation, thereby forming a pressure difference.

[0037] The disk body 41 is movably connected to the outer surface of the planetary disk 31, the second limiting groove 42 is formed on the inner surface of the disk body 41, the planetary disk 31 is movably connected to the inside of the second limiting groove 42, and the heat dissipation hole 43 is formed on the surface of the disk body 41.

[0038] The disk body 41 is ring-shaped, and the second limiting groove 42 is opened on the inner surface of the disk body 41. The internal array has teeth, and the surface teeth of the three planetary disks 31 just mesh with the internal teeth of the second limiting groove 42. There are multiple heat dissipation holes 43, which are arrayed on the surface of the disk body 41 to improve the heat dissipation performance of the disk body 41.

[0039] The working principle of the adaptive floating brake disc provided by this utility model is as follows:

[0040] During operation, the disc 41 is fixedly connected to the tire, and the tire drives the disc 41 to rotate at high speed. The planetary disk 31 meshes with the inner surface of the disc 41, and the first limiting groove 22 is fixed. The planetary disk 31 is subjected to the force of revolution and rotation of the teeth, so the planetary disk 31 revolves around the outer surface of the sun disk 21 while rotating on its own axis. The curved surface design of the fan blade 32 promotes airflow, thereby accelerating the flow of heat on its surface and reducing thermal friction between it and the surface of the disc 41. When braking, the brake pads inside the caliper 11 are connected to the surface of the disc 41 to brake the disc 41. The disc 41 is subjected to friction, and the rotation speed component decreases, thereby achieving deceleration.

[0041] Compared with related technologies, the adaptive floating brake disc provided by this utility model has the following beneficial effects:

[0042] This invention provides an adaptive floating brake disc, in which a connecting component 2 and a planetary component 3 are movably connected inside the brake disc assembly 4. The planetary component 3 can revolve around the sun while rotating on its own axis, increasing the flow on the surface of the disc body 41, thereby improving the heat dissipation performance and braking effect of the disc body 41.

[0043] Second Embodiment

[0044] Please refer to the following: Figure 3 Based on the adaptive floating brake disc provided in the first embodiment of this application, the second embodiment of this application proposes another adaptive floating brake disc. The second embodiment is merely a preferred embodiment of the first embodiment, and the implementation of the second embodiment will not affect the separate implementation of the first embodiment.

[0045] Specifically, the second embodiment of this application provides an adaptive floating brake disc that differs in that the adaptive floating brake disc has a braking assembly 5 disposed inside the caliper body 11, the braking assembly 5 includes a brake pad 51, the brake pad 51 is fixedly installed inside the caliper body 11, and one end of the brake pad 51 is fixedly connected to a cylinder 52.

[0046] There are two cylinders 52, and two brake pads 51 are fixedly connected to the surface of each cylinder 52. The two sets of brake pads 51 are fixedly installed on the inner surfaces of the left and right ends of the caliper body 11. By extending and retracting the brake pads 51, the two cylinders 52 can squeeze the surfaces of the disc body 41 at both ends to generate friction, thereby achieving tire braking.

[0047] An adjustment assembly 6 is provided inside the clamp body 11. The adjustment assembly 6 includes a bidirectional threaded rod 61, which is movably connected to the inner surface of the clamp body 11. A transmission belt 62 is fixedly connected to the surface of the bidirectional threaded rod 61, and a limit block 63 is threadedly connected to the surface of the bidirectional threaded rod 61. The limit block 63 is movably connected to the surface of the cylinder 52.

[0048] There are two bidirectional threaded rods 61. The two bidirectional threaded rods 61 are rotatably connected to the inner surfaces of the clamps 11 at the left and right ends of the cylinder 52. The transmission belt 62 consists of a belt with the surfaces of two pulleys meshing together. The two pulleys are fixedly connected to the surfaces at the center of the two bidirectional threaded rods 61. Thus, when one of the bidirectional threaded rods 61 is rotated, the two bidirectional threaded rods 61 can be rotated synchronously through the transmission belt 62. The surfaces of the two bidirectional threaded rods 61 are meshed with two limiting blocks 63. The limiting blocks 63 connected to the same surface form a set.

[0049] The working principle of the adaptive floating brake disc provided by this utility model is as follows:

[0050] When cylinder 52 wears out, one of the bidirectional threaded rods 61 is rotated, and the other bidirectional threaded rod 61 is driven to rotate synchronously through the transmission belt 62. As a result, the two sets of limit blocks 63 move relative to each other, and the distance between them is adjusted. Thus, the limit blocks 63 limit the cylinders. After the brake is reset, the two cylinders 52 are connected to the surface of the limit blocks 63 due to the limit of the limit blocks 63.

[0051] Compared with related technologies, the adaptive floating brake disc provided by this utility model has the following beneficial effects:

[0052] This utility model provides an adaptive floating brake disc, in which a rotatable bidirectional threaded rod 61 can adjust the distance between two sets of limiting blocks 63, thereby limiting the two cylinders 52. This allows the distance between the two cylinders 52 to be adjusted according to the wear condition of the cylinders 52, thus improving the service life of the cylinders 52.

[0053] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
