TECHNICAL FIELD
[0001] The utility model relates to the field technology of caliper, especially a motorcycle caliper. BACKGROUND
[0002] The motorcycle caliper is an important component for the braking system, which is usually installed on the front wheel and rear wheel of the motorcycle to control the braking of the wheel. The caliper is usually composed of two or more pistons, which apply pressure through hydraulic or mechanical systems to make the brake pads clamp the brake disc on the wheel, thereby slowing down or stopping the rotation of the wheel. The design and performance of the motorcycle caliper are crucial to the braking effect and safety of the motorcycle.
[0003] The current motorcycle caliper mainly includes a first half shell, a second half shell, a first piston and a second piston. The inner side of the first half shell is recessed with a first recess, and the second half shell is combined with the first half shell. The inner side of the second half shell is recessed with a second recess, and the second recess is opposite to the first recess. The first piston and the second piston are respectively embedded in the first recess and the second recess. However, the above-mentioned motorcycle caliper uses more materials, resulting in a heavier overall weight, and does not have a heat dissipation structure, which has a poor heat dissipation effect and adversely affects the braking effect. SUMMARY
[0004] Therefore, the utility model provides a motorcycle caliper which can effectively solve the problems of poor heat dissipation effect and heavy weight of the existing motorcycle caliper.

The inner side of the first half shell is recessed with a first recess, and the second half shell is combined with the first half shell. The inner side of the second half shell is recessed with a second recess, and the second recess is opposite to the first recess. The first piston and the second piston are respectively embedded in the first recess and the second recess. The outer side of the first half shell corresponds to the first recess to form a first heat dissipation fin, and the outer side of the second half shell corresponds to the second recess to form a second heat dissipation fin.
[0007] Preferably, the first recess is two, and the second recess is also two. The two second recesses are opposite to the two first recesses, and each first recess is provided with a first piston, and each second recess is provided with a second piston.
[0008] Preferably, the upper and lower surfaces of the first half shell are formed with a fixing hole, and the outer side of the first half shell is recessed with a hollow weight-reducing groove which is communicated with the fixing hole.
[0009] Preferably, the first half shell is formed with fixing holes on the upper and lower surfaces of both ends, and a hollow weight-reducing groove is arranged for each fixing hole.
[0010] Preferably, the second half shell is recessed with a weight-reducing notch on the outer side of both ends.
[0011] Preferably, the inner side of the first half shell is recessed with a plurality of screw holes, and the inner and outer sides of the second half shell are formed with a plurality of through holes, and a plurality of bolts are respectively screwed into the corresponding through holes and screw-connected with the corresponding screw holes.
[0012] The utility model has obvious advantages and beneficial effects compared with the prior art, specifically speaking, the above technical scheme can know that:
[0013] By forming the first heat dissipation fin on the outer side of the first half shell corresponding to the first recessed cavity, and forming the second heat dissipation fin on the outer side of the second half shell corresponding to the second recessed cavity, the heat dissipation of each heat dissipation fin can be accelerated, so that the temperature of the caliper during braking is effectively reduced, which is beneficial to guarantee the braking effect; and by cooperating the hollow weight-reducing groove and the weight-reducing notch, the material of the product is reduced, so that the overall weight of the product is lighter.

[0026] Please refer to Figs. 1 to 4 As shown in the drawings, the preferred embodiment of the present application shows the specific structure, comprising a first half shell 10, a second half shell 20, a first piston 30 and a second piston 40.
[0027] The inner side of the first half shell 10 is recessed with a first cavity 11, and the outer side of the first half shell 10 is formed with a first heat dissipation fin 12 corresponding to the first cavity 11. In this embodiment, the first half shell 10 is made of cast iron, and the first cavity 11 is two. In addition, the upper and lower surfaces of the first half shell 10 are formed with fixing holes 13, which are used for external installation and fixation. The outer side of the first half shell 10 is recessed with a hollow weight-reducing groove 14, which communicates with the fixing hole 13 to reduce the overall weight of the product. Moreover, the upper and lower surfaces of both ends of the first half shell 10 are formed with fixing holes 13, and each fixing hole 13 is provided with a hollow weight-reducing groove 14. In addition, the inner side of the first half shell 10 is recessed with a plurality of screw holes 15.
[0028] The second half shell 20 is spliced with the first half shell 10, and the inner side of the second half shell 20 is recessed with a second cavity 21, which is opposite to the first cavity 11. The outer side of the second half shell 20 is formed with a second heat dissipation fin 22 corresponding to the second cavity 21. In this embodiment, the second half shell 20 is made of cast iron, and the second cavity 21 is two, and the two second cavities 21 are opposite to the two first cavities 11 respectively. In addition, the outer side of both ends of the second half shell 20 is recessed with a weight-reducing notch 23 to reduce the overall weight of the product. In addition, the inner and outer sides of the second half shell 20 are formed with a plurality of through holes 24, and a plurality of bolts (not shown in the figure) pass through the corresponding through holes 24 and are screwed and connected with the corresponding screw holes 15, so that the second half shell 20 and the first half shell 10 are spliced and fixed together.
[0029] The first piston 30 and the second piston 40 are respectively embedded in the first cavity 11 and the second cavity 21. Each first cavity 11 is provided with a first piston 30, and each second cavity 21 is provided with a second piston 40.
[0030] In use, the product is installed on a motorcycle, and the brake oil enters the bottom of each first piston 30 and each second piston 40 through the oil channel to push each first piston 30 and each second piston 40 to move outward, thereby pushing the brake pad to clamp the brake disc to achieve braking. The arrangement of the first heat dissipation fin 12 and the second heat dissipation fin 22 can accelerate heat dissipation, thereby effectively reducing the temperature of the caliper when braking. Moreover, the arrangement of the hollow weight-reducing groove 14 and the weight-reducing notch 23 can reduce the weight.
