Description

Technical Field

[0001] This utility model relates to the technical field of caliper heat dissipation structure, specifically an automatic cooling brake caliper. Background Technology

[0002] Brake calipers are the core component of disc braking systems. They use hydraulic pressure to push friction pads to clamp the brake disc that rotates with the wheel, thereby generating friction to achieve braking.

[0003] Currently, commonly used brake calipers require additional energy for heat dissipation during the cooling process, and cannot achieve dual heat dissipation for both the caliper and the brake disc. For example, CN120557295A discloses an automatic cooling brake caliper, which includes a magnetorheological cooling caliper assembly, a self-circulating cooling caliper assembly, and a housing. The magnetorheological cooling caliper assembly and the self-circulating cooling caliper assembly are respectively installed on one side of the outer wall of the housing. The magnetorheological cooling caliper assembly is installed on one side of the outer wall of the self-circulating cooling caliper assembly.

[0004] As can be seen from the above-mentioned publicly available scheme, the brake caliper dissipates heat through a magnetorheological cooling caliper assembly and a self-circulating cooling caliper assembly. However, both the magnetorheological cooling caliper assembly and the self-circulating cooling caliper assembly require additional energy when working, and cannot achieve true "automatic" cooling. They also cannot dissipate heat from the brake disc during the cooling process. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an automatic cooling brake caliper to solve the problem that existing brake calipers cannot achieve true "automatic" cooling and cannot simultaneously dissipate heat from the brake disc.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic cooling brake caliper, comprising a caliper body, a brake disc, and a friction pad assembly disposed between the two. The caliper body contains a heat dissipation system, which includes a first heat dissipation channel and a second heat dissipation channel formed inside the caliper body. A turbine is disposed within the first heat dissipation channel. The turbine includes fan blades, a connecting shaft, and a driven gear. The fan blades are fixed to the connecting shaft and located within the first heat dissipation channel. The connecting shaft is rotatably mounted on the inner wall of the first heat dissipation channel via a sealed bearing. The driven gear is fixed to the connecting shaft. At the end, a gear ring is fixedly connected to the edge of the brake disc. The outer side of the gear ring meshes with the driven gear. This invention cleverly utilizes the power of the brake disc rotation to drive the turbine fan blades to rotate at high speed through the meshing of the gear ring and the driven gear. No additional energy is required, achieving true "automatic" cooling. Furthermore, by setting up the first and second heat dissipation channels, a complete cooling airflow path is formed. Cold air is drawn in from the air inlet, flows through the inside of the caliper body to remove heat, and then blows directly onto the brake disc and friction pad area from the two air outlets. The heat dissipation area is large and the efficiency is high, achieving dual high-efficiency cooling of the caliper body and the brake disc.

[0007] Preferably, the caliper body has an opening groove for accommodating the brake disc and is connected to the vehicle suspension system through a fixing plate. A friction pad assembly mounting plate is fixedly connected to the surface of the caliper body. A portion of the friction pads mounted on the friction pad assembly mounting plate are located in the opening groove, so that both the brake disc and the friction pads can be installed in the opening groove and actively cooled by air blowing.

[0008] Preferably, the inlet of the first heat dissipation channel is an air inlet located at one end of the caliper body, and its outlet is a first air outlet. The second heat dissipation channel is connected to the first heat dissipation channel through a connecting channel, and its outlet is a second air outlet. It can achieve efficient heat dissipation through forced air cooling.

[0009] Preferably, both the first air outlet and the second air outlet are located within the opening groove, and both the first air outlet and the second air outlet blow air towards the area between the friction pad assembly mounting plate and the brake disc, which can provide dual heat dissipation for the caliper body and the brake disc.

[0010] Preferably, the outer surface of the caliper body is provided with a plurality of heat dissipation plates and a plurality of heat dissipation strips. The plurality of heat dissipation plates and the plurality of heat dissipation strips are all made of aluminum alloy thermally conductive metal, which can improve the heat dissipation effect of the caliper body and at the same time improve its strength.

[0011] Preferably, the connecting channel is composed of a connecting pipe that connects the end of the first heat dissipation channel to the beginning of the second heat dissipation channel, so as to form a through heat dissipation duct.

[0012] Preferably, the outer side of the gear ring is provided with teeth that are evenly spaced, and the teeth are straight teeth. The rotation of the gear ring can drive the driven gear to rotate automatically.

[0013] Compared with the prior art, this utility model provides an automatic cooling brake caliper, which has the following beneficial effects: This invention cleverly utilizes the power of the rotating brake disc to drive the turbine fan blades to rotate at high speed through the meshing of the gear ring and the driven gear. It achieves true "automatic" cooling without the need for additional energy. Furthermore, by setting up the first and second heat dissipation channels, a complete cooling airflow path is formed. Cold air is drawn in from the air inlet, flows through the inside of the caliper body to carry away heat, and then blows directly onto the brake disc and friction pad area from the two air outlets. The heat dissipation area is large and the efficiency is high, achieving dual high-efficiency cooling of the caliper body and the brake disc. Attached Figure Description

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This utility model provides a technical solution: an automatically cooling brake caliper, comprising a caliper body 1, a brake disc 4, and a friction pad assembly disposed between the two. The caliper body 1 is made of cast metal and is connected to the axle via a fixing plate 15 to fix its installation position. A cooling system 2 is integrated inside the caliper body 1, including an air inlet 21, a first cooling channel 22, a first air outlet 23, a connecting pipe 24, a connecting channel 25, a second cooling channel 26, and a second air outlet 27, forming a complete airflow cooling path for dual cooling of the caliper body 1 and the brake disc 4. The caliper body 1 includes a first heat dissipation channel 22 and a second heat dissipation channel 26. A turbine 3 is installed in the first heat dissipation channel 22. The turbine 3 includes a fan blade 31, a connecting shaft 32 and a driven gear 34. The fan blade 31 is fixed on the connecting shaft 32 and located in the first heat dissipation channel 22. The connecting shaft 32 is rotatably mounted on the inner wall of the first heat dissipation channel 22 through a sealed bearing 33. The driven gear 34 is fixed to the end of the connecting shaft 32. A gear ring 41 is fixedly connected to the edge of the brake disc 4. The outer side of the gear ring 41 meshes with the driven gear 34. The rotation of the brake disc 4 can drive the gear ring 41 to rotate, which in turn drives the driven gear 34 to rotate, without the need for additional energy.

[0018] The caliper body 1 has an opening slot 11 for accommodating the brake disc 4 and is connected to the vehicle suspension system through a fixing plate 15. A friction pad assembly mounting plate 14 is fixedly connected to the surface of the caliper body 1. Part of the friction pads mounted on the friction pad assembly mounting plate 14 are located in the opening slot 11, so that both the brake disc 4 and the friction pads can be installed in the opening slot 11 and actively cooled by air blowing. The inlet of the first heat dissipation channel 22 is an air inlet 21 opened at one end of the caliper body 1, and its outlet is a first air outlet 23. The second heat dissipation channel 26 is connected to the first heat dissipation channel 22 through a connecting channel 25, and its outlet is a second air outlet 27. It can achieve efficient heat dissipation through forced air cooling.

[0019] The first air outlet 23 and the second air outlet 27 are both located within the opening slot 11. Both the first air outlet 23 and the second air outlet 27 blow air towards the area between the friction pad assembly mounting plate 14 and the brake disc 4, which can provide dual heat dissipation for the caliper body 1 and the brake disc 4. The outer surface of the caliper body 1 is provided with several heat dissipation plates 12 and several heat dissipation strips 13. The several heat dissipation plates 12 and several heat dissipation strips 13 are all made of aluminum alloy thermally conductive metal, which can improve the heat dissipation effect of the caliper body 1 and at the same time improve its strength.

[0020] The connecting channel 25 is composed of a connecting pipe 24, which connects the end of the first heat dissipation channel 22 and the beginning of the second heat dissipation channel 26, so as to form a through heat dissipation air duct. The outer side of the gear ring 41 is provided with teeth 42 distributed at equal intervals. The teeth 42 are straight teeth. The rotation of the gear ring 41 can drive the driven gear 34 to rotate automatically.

[0021] The working principle of this device is as follows: When the vehicle is in motion, the brake disc 4 drives the gear ring 41 to rotate together. Since the caliper body 1 is fixed, the rotating gear ring 41 drives the driven gear 34 that meshes with it to rotate, thereby driving the connecting shaft 32 and the fan blade 31 to rotate at high speed. The rotation of the fan blade 31 generates suction, which draws external cold air into the first heat dissipation channel 22 from the air inlet 21. When the airflow flows through the first heat dissipation channel 22, it absorbs the heat of the caliper body 1. Subsequently, part of the airflow is blown out from the first air outlet 23, and the other part enters the second heat dissipation channel 26 through the connecting pipe 24. After secondary heat exchange, it is blown out from the second air outlet 27. Finally, all the heated airflow is guided to the surface of the brake disc 4, forming a highly efficient forced air cooling system, which significantly reduces the temperature of the entire braking system.
