Heat-dissipation type wear-resistant brake pad

Abstract

The invention discloses a heat-dissipation type wear-resistant brake pad comprising a metal sheet and a friction block. The metal sheet and the friction block are laminated into a whole, buffer slopes are arranged on two sides of the friction block, and micro pits are formed in the friction surface, toward a brake disc, of the friction block. A first arc-shaped slot group and a second arc-shaped slot group are formed in the friction surface, toward the brake disc, of the friction block. The arc protruding direction of arc-shaped slots in the first arc-shaped slot group is identical to the rotation direction of the brake disc, and the arc protruding direction of arc-shaped slots in the second arc-shaped slot group is opposite to the rotation direction of the brake disc. Depth of the arc-shaped slots in the first arc-shaped slot group is larger than that of the arc-shaped slots in the second arc-shaped slot group, and two ends of each arc-shaped slot in the first arc-shaped slot group and the second arc-shaped slot group extend to the edge of the friction block.

Description

technical field [0001] The invention relates to the technical field of automobile braking, in particular to a heat dissipation type wear-resistant brake pad. Background technique [0002] Brake pads are the executive components that perform braking while the car is running. The brake pads clamp the brake disc that rotates with the tires, and the brake pads rub against the brake disc to convert the driving kinetic energy of the car into heat energy, thereby realizing the braking of the car. operate. During the braking process, the friction between the brake pad and the brake disc will accumulate a large amount of heat energy in a short time, especially when performing emergency braking at high speed, the temperature of the brake pad will accumulate and rise in a short time; when braking After the temperature of the pad rises to a certain value, the braking effect of the brake pad will be greatly reduced or even invalid. [0003] Therefore, the friction performance and heat ...

AI Technical Summary

Problems solved by technology

However, the straight groove is arranged in the middle of the friction block, which cannot evenly dissipate heat from the entire friction block, and the rotation direction of the brake disc is perpendicular to the straight groove, so the heat dissipation effect of the straight groove is relatively poor. In addition, dust is also easy to accumulate in the straight groove. In the groove, which affects the performance stability of the friction block; when the car is braking in normal driving and reverse state, the straight groove cannot achieve good heat dissipation effect of multi-working condition braking
