Description

Technical Field

[0001] The utility model relates to the field of brake discs, in particular to a special-shaped rib heat dissipation brake disc. Background Art

[0002] The brake disc and the tire are fixed and rotate at the same speed. When braking, the oil pressure is used to push the brake shoe to contact the friction surface of the brake disc and the brake wheel. The friction generated by the contact is used to suppress the rotation of the tire to complete the braking action. Because the friction process generates a lot of heat, the temperature of the brake pad will rise accordingly. When the maximum temperature exceeds the limit, the friction coefficient will begin to decrease, and the braking effect will become worse and worse, which can easily cause brake failure and cause accidents. This phenomenon is the thermal decay of the brake.

[0003] The utility model patent with application number 201420235914.1 discloses a brake disc, in which a plurality of heat dissipation ribs are arranged. By arranging a plurality of arc-shaped grooves on the heat dissipation ribs, the contact area between the wind and the heat dissipation ribs is increased, thereby improving the heat dissipation efficiency. However, in this scheme, the groove design fails to fully increase the contact area between the heat dissipation ribs and the wind, and its heat dissipation channel is relatively limited, which cannot accelerate the heat dissipation.

[0019] The following is combined with Figure 1 To Attachment Figure 3 The principles and features of the present invention are described, and the examples given are only used to explain the present invention, and are not used to limit the scope of the present invention.

[0020] A special-shaped rib heat dissipation brake disc comprises an assembly disc 1, a first disc 2, a second disc 3 and ribs 4. The assembly disc 1 and the first disc 2 are an integral structure, and a mounting hole 5 is provided on the assembly disc 1 for fixing to a tire. The first disc 2 and the second disc 3 are in a parallel structure and are fixedly connected by ribs 4. The ribs 4 are provided in a plurality of groups and are evenly distributed in a spiral shape around the axis of the two discs between the first disc 2 and the second disc 3. Specifically, the ribs 4 include short bending ribs 40 and long bending ribs 43, and the short bending ribs 40 and the long bending ribs 43 are arranged at intervals, and the first disc 2 and the second disc 3 are connected by the long bending ribs 43. In one embodiment, the ribs 4 can be provided in 37 groups.

[0021] The short bending rib 40 includes a short rib 1 41 and a short rib 2 42. The short rib 1 41 is arranged on the first disc 2, and the short rib 2 42 is arranged on the second disc 3. In one embodiment, the short rib 1 41 and the short rib 2 42 are symmetrically arranged on the first disc 2 and the second disc 3, and a gap is formed between the two to facilitate air flow. The cross-section of the short rib 1 41 and the short rib 2 42 can adopt a streamlined structure that is conducive to air flow, and the cross-section of the short rib 1 41 and the short rib 2 42 can also adopt a right-angle trapezoidal structure, wherein one end of the right angle is close to the outer edge of the first disc 2 and the second disc 3.

[0022] One side of the long curved rib 43 is a wavy structure, and both sides of the long curved rib 43 can also be set as a wavy structure. The wavy structural design increases the contact area between the brake disc body and the air, thereby increasing the heat dissipation effect, and through the cooperation of the short curved rib 40 and the long curved rib 43, the rib 4 and the brake disc body form a ventilation groove of a special shape. When the brake disc rotates, the outer surface of the brake disc forms air turbulence due to the brake disc ventilation groove, so that the air can take away the heat on the brake disc faster.

[0023] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
