Description

Technical Field

[0001] This utility model relates to the technical field of bicycles, specifically to a wear-resistant hydraulic disc brake for bicycles. Background Technology

[0002] When a bicycle hydraulic disc brake is operated, the piston inside the brake lever compresses the hydraulic fluid when the rider squeezes the brake lever. The pressure is transmitted to the caliper through the oil line, which pushes the piston to drive the brake pads to clamp the disc, generating friction to slow down or stop the wheel.

[0003] However, common bicycle hydraulic disc brakes experience high wear. With frequent use, the temperature of the caliper, brake pads, and disc rises rapidly, significantly increasing wear and reducing lifespan. Therefore, those skilled in the art have provided a wear-resistant bicycle hydraulic disc brake to address the problems mentioned in the background section. Utility Model Content

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A wear-resistant bicycle hydraulic disc brake includes a caliper, with drive pistons on both sides of the caliper, and a braking mechanism at the output end of each drive piston for braking in conjunction with a disc mounted on the bicycle wheel axle.

[0006] Preferably, both braking mechanisms include a connecting disc, with limit blocks fixedly installed on both sides of the top of the connecting disc, and limit grooves formed on both sides inside the caliper. Limit rods are fixedly installed in the limit grooves, and the limit blocks are movably installed in the limit grooves, with the limit blocks and limit rods being movably connected.

[0007] Preferably, a heat dissipation groove is provided on the inner side of the connecting plate, and a plurality of support shafts are fixedly installed in the heat dissipation groove. A plurality of heat dissipation holes are provided on one side of the connecting plate, and the plurality of heat dissipation holes are all connected to the heat dissipation groove.

[0008] Preferably, a brake disc is fixedly installed on the other side of the connecting disc, and the connecting disc is made of a material with high rigidity and high thermal conductivity.

[0009] Preferably, the caliper has mounting slots on both sides and at the top, and a cooling fan is fixedly installed in each mounting slot.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] With its designed braking mechanism, the calipers are typically installed at a certain angle. When the bicycle is in motion, the inner side of the caliper can trap the airflow. Through the design of the connecting disc, the airflow can pass through the heat dissipation grooves and several heat dissipation holes, and the airflow can drive the cooling fan to rotate, thereby improving the ventilation efficiency, cooling the connecting disc, and then cooling the brake disc, effectively reducing the wear of the brake disc.

[0016] The present invention will be further described in detail below with reference to embodiments:

[0017] This utility model discloses a wear-resistant hydraulic disc brake for bicycles. (See reference...) Figure 1-3 It includes a caliper 1, with drive pistons 2 on both sides of the caliper 1. The output ends of the drive pistons 2 on both sides are equipped with a braking mechanism for cooperating with the disc mounted on the bicycle wheel axle for braking.

[0018] By adopting the above technical solution, the present invention, through the setting of the braking mechanism, since the caliper 1 is generally installed at a certain angle, can catch the wind on the inner side of the caliper 1 when the bicycle is moving. Through the setting of the connecting plate 3, the wind can pass through the heat dissipation groove 7 and several heat dissipation holes 9, and the wind can drive the cooling fan 12 to rotate, thereby improving the ventilation efficiency, thereby dissipating heat on the connecting plate 3, and then dissipating heat on the brake disc 10, effectively reducing the wear of the brake disc 10.

[0019] Reference Figure 1-3 Both braking mechanisms include a connecting disc 3. Limiting blocks 4 are fixedly installed on both sides of the top of the connecting disc 3. Limiting grooves 5 are opened on both sides inside the caliper 1. Limiting rods 6 are fixedly installed in the limiting grooves 5. Limiting blocks 4 are movably installed in the limiting grooves 5, and the limiting blocks 4 and the limiting rods 6 are movably connected.

[0020] By adopting the above technical solution, the limiting block 4 facilitates movement within the limiting groove 5, thereby driving the connecting disc 3 to move the brake disc 10, which improves the stability of the movement of the connecting disc 3.

[0021] Reference Figure 1-3 The inner side of the connecting plate 3 is provided with a heat dissipation groove 7, and several support shafts 8 are fixedly installed in the heat dissipation groove 7. Several heat dissipation holes 9 are provided on one side of the connecting plate 3, and the several heat dissipation holes 9 are all connected to the heat dissipation groove 7.

[0022] By adopting the above technical solution, the heat dissipation grooves 7 and heat dissipation holes 9 facilitate the flow of air through the heat dissipation grooves 7 and several heat dissipation holes 9 when the bicycle is in motion, and the air can drive the cooling fan 12 to rotate, thereby improving the exhaust efficiency, thus dissipating heat from the connecting disc 3, and further dissipating heat from the brake disc 10, effectively reducing the wear of the brake disc 10.

[0023] Reference Figure 1-3 A brake disc 10 is fixedly installed on the other side of the connecting disc 3, and the connecting disc 3 is made of a material with high rigidity and high thermal conductivity.

[0024] By adopting the above technical solution, and by making the brake disc 10 with a material that has high rigidity and high thermal conductivity, it can provide strong support and rapid heat dissipation, thereby reducing wear.

[0025] Reference Figure 1-3 The caliper 1 has mounting slots 11 on both sides and top, and cooling fans 12 are fixedly installed in the mounting slots 11.

[0026] By adopting the above technical solution, the cooling fan 12 makes the cooling slot 7, cooling hole 9 and mounting slot 11 form a cooling air duct, which can improve air circulation efficiency, accelerate heat dissipation and reduce operating temperature.

[0027] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
