Description

Technical Field

[0001] This patent relates to the field of brake technology, specifically a fixed-caliper disc brake with heat dissipation function. Background Art

[0002] Brakes are an indispensable part of automobiles, but today's brakes are usually of a caliper disc structure, and the components lack a device that can quickly dissipate heat, which shortens the service life of the brake disc and the brake caliper. At the same time, today's brake discs often have some holes in them in order to quickly dissipate heat. Some large vehicles also have fixed caliper disc brakes with water tanks. Drivers can regularly spray the brake discs and friction blocks with water in the water tank to cool them down. However, in hot weather such as summer, the water in the water tank will also become hot, so the cooling and heat dissipation effect after spraying will also become worse. For this reason, we propose a fixed caliper disc brake with heat dissipation function. Utility Model Content

[0003] In view of the shortcomings of the prior art, the purpose of this patent is to provide a fixed-caliper disc brake with a heat dissipation function. This patent installs a water tank on the top of the brake caliper, and cooling fins are fixed on the left and right side walls of the water tank through mounting rings. The cold surface of the cooling fin is located inside the water tank, and the hot surface of the cooling fin is located outside the water tank. The water in the water tank can be cooled by the cold surface of the cooling fin, so that the water mist sprayed from the nozzle is low-temperature water mist, which effectively increases the heat dissipation and cooling effect on the brake disc and friction head, and improves the service life of the overall brake.

[0020] A ring body 13 is integrally formed on the side wall of the refrigeration fin 12, and a mounting ring 14 is attached to the outer side of the ring body 13. Mounting holes 15 are provided at the four corners of the mounting ring 14 and the ring body 13. Bolts 16 are provided in the mounting holes 15. The ends of the bolts 16 pass through the rubber ring 11 and are screwed into the threaded groove 10.

[0021] By tightening the bolts 16 , the mounting ring 14 can be pressed against the ring body 13 , and the ring body 13 can be pressed against the rubber ring 11 .

[0022] Specifically, the shapes of the ring body 13 and the mounting ring 14 match the shape of the annular groove 9 .

[0023] The shapes of the ring body 13 and the mounting ring 14 match the shape of the annular groove 9 to define the mounting positions of the ring body 13 and the mounting ring 14 and the water tank 3 .

[0024] Specifically, the inner side wall of the mounting ring 14 does not contact the cooling fins 12 .

[0025] Specifically, the inner wall of the mounting hole 15 on the mounting ring 14 is provided with a circular groove 17, and a connecting ring 18 is integrally formed on the side wall of the bolt 16. The connecting ring 18 is located in the circular groove 17, and the outer wall of the connecting ring 18 and the inner wall of the circular groove 17 slide relatively. The side wall of the bolt 16 does not contact the inner wall of the mounting hole 15.

[0026] By setting a connecting ring 18 (annular) in the annular groove 17, the bolt 16 and the mounting ring 14 are integrated. When the refrigeration plate 12 needs to be disassembled for maintenance or replacement, the mounting ring 14 needs to be disassembled. At this time, the bolt 16 will not be separated from the mounting ring 14 through the connecting ring 18, avoiding the loss of parts.

[0027] Specifically, a sealing rubber layer is provided in each through hole of the brake caliper 1 for accommodating the water pipe 5 .

[0028] Specifically, a fan 19 is fixedly mounted on the bottom of the outer side surface of the mounting ring 14 .

[0029] The fan 19 can blow air upward, which is beneficial to take away the heat on the hot surface of the cooling plate 12, avoid heat accumulation, and increase the service life of the cooling plate 12.

[0030] Working principle: Hydraulic oil enters the left oil pipe of brake caliper 1, and the hydraulic oil enters brake caliper 1. The hydraulic oil pushes the piston in brake caliper 1, so that the two pistons approach each other, and the friction block at the end of the piston contacts the brake disc 2 to reduce the speed.

[0031] The cold surface of the cooling plate 12 can cool the water in the water tank 3. The driver can control the pump body 4 to start pumping out the cooling water in the water tank 3 and spray it out from the nozzle 6 to cool the brake disc 2 and the friction block.

The water in the water tank can be cooled by the cold surface of the cooling fin, so that the water mist sprayed from the nozzle is low-temperature water mist, which effectively increases the heat dissipation and cooling effect on the brake disc and friction head, and improves the service life of the overall brake.
