Problems solved by technology

This seemingly simple question actually involves more complex technical parameters and other indicators, including the uniform distribution of the contact force between the brake pad and the brake disc, the thermal degradation of the brake pad, and the relationship between the steel back and the friction material. Adhesive strength and other indicators
[0003] The existing brake pads have uneven braking force distribution during the braking process, resulting in uneven wear of the brake pads, local damage, and poor heat dissipation. As the temperature increases, the brake pads will expand and deform during the braking process, and accompanied by Continuous braking will generate vibration and noise of the brakes, and the moisture resistance of the brake pads will be reduced in rainy and snowy days. These conditions will lead to poor stability of braking force, reduced safety performance, and shortened service life

Embodiment Construction

[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] like figure 1 As shown, a brake pad for a disc brake includes a friction layer 1 and a steel back layer 2, the friction layer 1 and the steel back layer 2 are fan-shaped, the steel back layer 2 is located above the friction layer 1, and passes through the metal Binder 3-phase bonding, such as figure 2 as shown, figure 1 The cross-sectional view of B-B of the steel back layer 2 and the friction layer 1 is engraved with a layer of diamond-shaped mesh grooves. The diamond-shaped mesh grooves can increase the bonding strength between the friction layer 1 and the steel back layer 2, thereby effectively reducing The problem of the reduction of the bond strength between the friction layer 1 and the steel back layer 2 caused by the long-term braking process is solved.

[0027] like image 3 As shown, the braking surface of the friction layer 1 is provided with seve...

Abstract

The invention discloses a brake pad for a disc brake. The brake pad comprises a friction layer and a steel backing layer, the steel backing layer is positioned above the friction layer and adhered to the same through a metal binding agent, a braking face of the friction layer is provided with a plurality of arc grooves which are distributed transversely and penetrate through the friction layer, and skewed slots which are distributed obliquely, longitudinally and uniformly and lead to the edge of the friction layer are formed in the outer sides of the arc grooves on two sides. A layer of rhombus net grooves is graved on a face, fitting with the friction layer, of the steel backing layer. Two cylindrical bosses are symmetrically arranged on the upper surface of the steel backing layer, and the outer edges of the bosses are provided with asterisk-shaped reinforcing ribs. The brake pad for the disc brake has the advantages of vibration reduction, noise suppression, long service life, high stability, good heat effect, high safety, effectiveness in improvement of safety of the brake and good application prospect.

Description

technical field [0001] The invention relates to the field of automobile mechanical parts, in particular to a brake pad for a disc brake. Background technique [0002] Brake pads are one of the indispensable parts in the braking process of automobile disc brakes. At the same time, they are also a kind of safety parts. role. This seemingly simple question actually involves more complex technical parameters and other indicators, including the uniform distribution of the contact force between the brake pad and the brake disc, the thermal degradation of the brake pad, and the relationship between the steel back and the friction material. Adhesive strength and other indicators. [0003] The existing brake pads have uneven braking force distribution during the braking process, resulting in uneven wear of the brake pads, local damage, and poor heat dissipation. As the temperature increases, the brake pads will expand and deform during the braking process, and accompanied by The c...
