Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a split heat dissipation type brake disc. Background Art

[0002] To put it simply, a brake disc is a round plate that rotates when the car is moving. Brake discs are divided into solid brake discs and ventilated discs according to their structure. Solid brake discs are just a piece of metal disc with a very simple structure. Ventilated discs are divided into two types: scored discs and perforated discs. Their common function is to improve the cooling performance of the brake discs. The brake discs generate braking force by clamping the brake calipers. When you step on the brakes, it clamps the brake discs to slow down or stop the car.

[0003] However, in the existing equipment, the brake disc is integrally formed by casting, that is, the brake disc hub and the brake disc are integrally formed by a casting process. This brake disc has slow heat conduction, which affects the service life of the brake disc. Therefore, a split heat dissipation brake disc is proposed. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Reference Figures 1 to 3, the utility model provides a split heat dissipation brake disc: it includes a first disc body 1 and a second disc body 2, a plurality of support blocks 3 are fixedly arranged between the first disc body 1 and the second disc body 2, the distance between the first disc body 1 and the second disc body 2 on one side is greater than the thickness of the two disc bodies, the heat generated by the edge will increase the heat dissipation area in the middle and further improve the heat dissipation efficiency, a plurality of blocking frames 6 are fixedly arranged on the first disc body 1, a brake disc hub 7 is fixedly arranged on the side of the first disc body 1 away from the second disc body 2, the brake disc hub 7 is made of aluminum alloy, the brake disc hub 7 made of aluminum alloy can accelerate heat dissipation, and at the same time can also improve the corrosion resistance of the equipment, the first disc body 1 and the second disc body 2 are both made of cast iron, a plurality of positioning shaft holes 8 and half-shaft through holes 10 are arranged on the brake disc hub 7, the half-shaft through holes 10 are located at the center of the plurality of positioning shaft holes 8, a plurality of connecting plates 9 are fixedly arranged on the outer wall of the brake disc hub 7, the connecting plate 9 is fan-shaped, the connecting plate 9 and the blocking frame 6 are both provided with internal threaded holes, and the setting of the blocking frame 6 can block and limit the connecting plate 9, thereby playing a role of reinforcement;

[0026] The surfaces of the first disk body 1 and the second disk body 2 are provided with a plurality of rows of heat dissipation holes 4 and a plurality of through grooves 5. The heat dissipation holes 4 and the through grooves 5 can improve the heat dissipation performance of the brake disc. The through grooves 5 can discharge the powder generated during braking to prevent the powder from adhering to the disk body and reducing the braking performance of the brake disc. There are twelve rows of heat dissipation holes 4, each row of heat dissipation holes 4 has three heat dissipation holes, and there are five through grooves 5. The through grooves 5 are arranged in a circular equidistant array on the first disk body 1 and the second disk body 2.

[0027] Working principle: During use, multiple heat dissipation holes 4 and through grooves 5 can play a role in rapid heat dissipation. The heat generated by the disc body during braking will be diffused through the heat dissipation holes 4 and through grooves 5, which can improve the heat dissipation efficiency of the brake disc. When the brake disc is in contact with the brake pad, the friction between the brake pad and the brake disc will produce a large amount of powder, which can be discharged through the through grooves 5 or heat dissipation holes 4, which can minimize the amount of powder attached to the surface of the brake disc and ensure braking performance. The brake disc and the brake disc hub 7 are separate, which can reduce the overall area of ​​the brake disc. Therefore, when the brake disc is hot, the heat conduction speed of the brake disc can be accelerated. If the surface of the brake disc is uneven and needs to be replaced, the multiple screws on the blocking frame 6 and the connecting plate 9 can be removed one by one, and the two disc bodies can be replaced. The brake disc hub 7 can continue to be used, which can reduce the cost of use. The setting of the blocking frame 6 can block and limit the connecting plate 9 to play a reinforcement role.
