Heat-dissipation structure of brake pad

摘要

A heat-dissipation structure of brake pad includes a main plate. The main plate has a first heat-dissipation portion at a first end and a second heat-dissipation portion at a second end. The first heat-dissipation portion includes a plurality of heat-dissipation pillars protruded from the main plate. The second heat-dissipation portion includes a plurality of protrusions or recesses formed on the main plate. The main plate has a brake pad on a face thereof opposite to the heat-dissipation pillars. The brake pad is located between the first and the second heat-dissipation portions. When the main plate is disposed on a caliper body, the first and the second heat-dissipation portions are exposed at two ends of the caliper body respectively to increase heat-dissipation area.

1. A heat-dissipation structure of brake pad, adapted for being disposed on a caliper device wherein the caliper device includes a caliper body having a fixed-volume receiving room formed through the caliper body, the heat-dissipation structure of brake pad includes:
a main plate, having a first face and an opposite second face, the main plate having a first heat-dissipation portion at a first end and a second heat-dissipation portion at a second end, the first heat-dissipation portion including a plurality of heat-dissipation pillars protruded from the first face, the second heat-dissipation portion including a plurality of protrusions protruded from at least one of the first face and the second face, the main plate having a brake pad on the second face, the brake pad being located between the first heat-dissipation portion and the second heat-dissipation portion, when the main plate is disposed on the caliper body, the main plate penetrates the receiving room, the first heat-dissipation portion and the second heat-dissipation portion are exposed outside the caliper body at two ends of the caliper body respectively, and the brake pad is received in the receiving room; wherein the first face is for being pushed by a piston in a direction perpendicular to the first face, and the second face is for attachment of the brake pad; wherein each of the heat-dissipation pillars and each of the protrusions protrude in the direction perpendicular to the first face; wherein a first direction is defined from the first end to the second end of the main plate, each protrusion is an elongated rib, the elongated ribs are spacedly arranged along a second direction, the second direction is perpendicular to the first direction; wherein an imaginary line defined by the two ends of each elongated rib along an extending direction of the elongated rib is unparallel to the first direction, each elongated rib obliquely extends from a bottom-right side to an upper-left side of the first face of the main plate, the main plate has a third end and an opposite fourth end along the second direction, a distance from an end of each elongated rib near the second end of the main plate to the second end of the main plate is tapered from the third end to the fourth end of the main plate.
