Description

A kind of automobile disc brake friction pad with strong heat dissipation

technical field

The invention relates to the technology of auto parts, in particular to a friction pad of an auto disc brake with strong heat dissipation.

Background technique

With the rapid development of expressways and the increasing development trend of vehicle ownership, the traffic accidents brought about are also increasing. According to relevant survey statistics, traffic accidents caused by problems such as insufficient braking of the vehicle itself account for a large proportion.

The braking system is an important part of the vehicle, which directly affects the safety of the vehicle. Automobile brakes are divided into two types: disc brakes and drum brakes. The disc brake brakes through a disc (brake disc) that is fixed to the tire and the hub and rotates at the same speed. When braking, oil pressure is used to push the piston in the brake caliper. It generates braking force and contacts with the brake disc to generate friction and finally stops the vehicle. Because of its light weight, simple structure, convenient adjustment, stable braking effect, good thermal stability and water stability, it is widely used in on small vehicles.

When the car brakes are braked, especially when working for a long time or continuous emergency braking, a large amount of heat will be generated, which will cause the brakes to undergo thermal recession, thereby damaging the brake friction linings and seriously affecting the braking performance, which will increase the occurrence of traffic accidents. possibility. At the same time, high temperature will accelerate the fatigue damage of automobile disc brake parts, and the disc brake lining for automobiles is the brake brake component of the brake. The traditional lining is mainly composed of a lining body and a friction plate arranged on the lining body. During use, the brake is mainly stopped by the friction of the friction plate.

Due to repeated friction will generate a lot of heat, the heat accumulated on the brake friction lining cannot be dissipated, which will not only affect the normal use of the lining, but also cause serious wear of the lining, which will easily cause brake failure and cause traffic accidents .

Contents of the invention

The technical problem to be solved by the present invention is to provide a friction pad of automobile disc brake with strong heat dissipation, the heat dissipation fin has fast heat dissipation and long service life, so as to overcome the deficiencies of the prior art.

The present invention is achieved like this:

A friction pad for automobile disc brakes with strong heat dissipation, including a brake pad back plate, connecting pieces and slots connected to the corresponding positions of the disc brake are arranged around the brake pad back plate, and the friction lining is fixed on the support On the front side of the back plate, vertical heat dissipation strips parallel to each other are arranged on the working surface of the friction lining, and the bottom ends of the vertical heat dissipation strips are aligned with the bottom ends of the friction lining.

In the aforesaid friction pad of an automobile disc brake with strong heat dissipation, the cross-sectional area of the heat dissipation belt is a shallow groove structure in the shape of a semicircle.

In the aforesaid friction pad of an automobile disc brake with strong heat dissipation, the length of the heat dissipation band is not greater than 1/3 of the length of the friction lining at the corresponding position.

Due to the adoption of the above technical solution, compared with the prior art, the present invention provides a vertical cooling strip on the end surface of the friction lining body, so that the lining can be used without affecting the braking performance during use. The heat accumulated on the lining body is quickly dissipated through the heat dissipation belt, which provides a guarantee for the normal use of the lining and prolongs its service life. The vertical heat dissipation belt of the friction plate also acts as a chip removal groove. The arrangement of the vertical heat dissipation strips functioning as chip removal slots can discharge the debris generated by the friction of the friction plate out of the brake, preventing it from remaining on the friction plate and affecting the braking process. At the same time, mass production of the brake block can save costs.

detailed description

Embodiment of the present invention: a friction pad for automobile disc brakes with strong heat dissipation, as shown in the accompanying drawings, includes a brake pad back plate 10, and positions corresponding to the disc brake are set around the brake pad back plate 10 The connecting piece 13 and the slot 14 are connected, and the feature is that the friction lining 11 is fixed on the front side of the support back plate 10, and the vertical heat dissipation strips 12 parallel to each other are arranged on the working surface of the friction lining 11, and the vertical The bottom end of the heat dissipation belt 12 is aligned with the bottom end of the friction lining 11 .

Wherein the cross-sectional area of the heat dissipation strip 12 is a semicircular shallow groove structure, and the length of the heat dissipation strip 12 is not greater than 1/3 of the length of the friction lining 11 at the corresponding position.

This embodiment is used for a disc brake for automobiles. The disc brake includes a brake caliper 1 and an inspection hole 2 thereon, an air release screw 3, a brake piston housing 4, a brake disc 5 and a brake disc. Ventilation holes 6, brake caliper bracket 7, brake pads with good heat dissipation performance and vertical heat dissipation belts with chip removal slots, including inner brake pads 8 and outer brake pads 9, etc. When braking, the oil is pressed into the wheel cylinder, and the piston presses the two brake pads against the brake disc under hydraulic pressure to generate friction torque for braking. The friction between the brake pad and the brake disc is The vehicle slows down until it comes to a stop. The invention improves the heat dissipation of the disc brake by changing the structures of the inner brake pad and the outer brake pad.

In the above scheme, by setting up a heat dissipation belt on the friction lining working surface of the lining body, the heat accumulated on the lining body can be quickly dissipated through the heat dissipation belt during the use of the lining, which is the best for the lining body. Normal use provides protection and prolongs its service life. At the same time, the setting of the heat dissipation belt groove saves the use of friction materials, and can save a certain amount of cost for mass production.

In this embodiment, the friction lining 1 and the lining support back plate 1 are integrated, and the production stage adopts the pressure embedding of the friction lining on the lining carrier plate by extrusion under high pressure and elevated temperature. , which is beneficial to reduce production costs and facilitate installation.

In this embodiment, the heat dissipation belt provided on the friction lining also acts as a chip removal groove, which can discharge the debris generated by the friction of the friction lining after the braking process, so as to prevent it from remaining on the friction lining and affecting the to the brakes.
