Problems solved by technology

However, when the friction block and the brake disc are in contact with each other, a large amount of heat will be generated, and the heat will be transferred to the piston rod through the back plate, and then transferred to the oil in the hydraulic cylinder, causing the temperature of the oil to rise and the volume to change, thereby affecting the brake. Braking precision and stability

Abstract

The invention relates to the technical field of automobile accessories, and discloses a heat dissipation type brake pad. The heat dissipation type brake pad comprises a back plate and a friction block. A heat insulating layer is arranged between the back plate and the friction block. Piston rod limiting holes are formed in the outer side face of the back plate. Heat insulating cavities are formed in the bottoms of the piston rod limiting holes and filled with heat insulating filler. Cover plates are arranged at the opening ends of the heat insulating cavities. Supporting protruding rings are arranged at the positions of the inner walls of the bottoms of the piston rod limiting holes. Flow guiding grooves are formed in the outer side face of the back plate and communicate with the piston rod limiting holes. The bottom faces of the flow guiding grooves are flush with the bottom faces of the piston rod limiting holes. In the braking process of the brake pad, heat transmitted to oil in a hydraulic cylinder can be reduced to the maximum degree, and therefore the service life of the hydraulic cylinder is prolonged, and the stability of the braking performance of the brake pad is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts, in particular to a heat dissipation brake pad. Background technique [0002] Brake pads are also called brake pads. In the braking system of automobiles, brake pads are the most critical safety parts. Brake pads are mainly used in the braking of automobiles, motorcycles and other transportation. The brake pad is generally composed of a back plate and a friction block, and the back plate is usually a steel plate. The brake pad is installed in the brake mounting seat in the brake assembly. The outer edge of the back plate of the brake pad is limited by the reed. The inner edge of the back plate of the brake pad is in contact with the brake mounting seat. The back of the back plate is in contact with the hydraulic cylinder. The piston rod is contacted and connected, and the piston rod of the hydraulic cylinder stretches to drive the friction block to contact and separate from the brake disc, the...
