Abstract

The utility model discloses a disc-type brake pad of commercial vehicles. The disc-type brake pad of commercial vehicles comprises a steel back and friction materials which are attached to the steel back. The disc-type brake pad of the commercial vehicles is characterized in that two grooves are arranged on a supporting portion on a lower portion of the steel back. After the two grooves are arranged on the supporting portion on the lower portion of the steel back, contact area of the steel back and a brake caliper body is reduced, space is reserved on a contact portion, and the brake pad is beneficial for accumulation and discharge of friction dusts. Therefore, braking jitter and brake noises due to poor contact can be effectively avoided. As friction during braking is along the transverse direction, intensity of the brake pad after slotting can not be influenced.

Description

A kind of disc brake pad of commercial car
Technical field
The utility model belongs to the auto parts and components field, particularly a kind of disc brake pad of commercial car.
Background technique
Disc brake pad is to be fitted each other through the high temperature compacting by steel backing and friction material layer to constitute.Disc brake device be with static brake disc clamp along with the brake disc of tyre rotation to produce frictional force, the speed that turns a wheel reduces.When stepping on braking pedal, the piston in the general braking pump can be pushed, and in brake fluid line build-up pressure; Pressure is sent to the piston of the wheel cylinder on the brake clamp via brake oil; The piston of wheel cylinder can outwards move and promote brake block and remove to clamp brake disc after being under pressure, and makes brake block and brake disc rub; To reduce vehicle wheel rotational speed, make car deceleration or stop.In the brake system of automobile, brake block is the breaking piece of most critical, and the quality of all braking effects all is that brake block plays a decisive role.
The steel backing of brake block mainly plays a supportive role.The existing lower support position that is used for the brake block steel back on heavy goods vehicles and the bus is directly stamping forming.The steel backing bottom contacts with the stent support of brake calipers; The friction ash drops on the support of brake calipers in the brake process; When dust stratification more for a long time, can cause brake block and brake calipers surface of contact not enough, be prone to produce brake judder and braking force deficiency; Can produce brake noise simultaneously, when serious even can cause the brake safe accident.
Summary of the invention
In order to overcome the above-mentioned defective of existing disc type brake block steel back, the utility model provides the disc brake pad of commercial car, the brake noise that can effectively avoid brake judder and cause because of brake block and caliper bad connection.
A kind of disc brake pad of commercial car, comprise steel backing and with the friction material that steel backing fits, it is characterized in that the lower support position of steel backing is provided with two grooves.
Further, said groove is an arch.
Further, said recess width is 10 mm.
Further, said depth of groove is 3mm.
After two grooves are opened at the lower support position of steel backing,,, help the accumulation and the discharge of each brake back friction dust simultaneously at the contact segment slot milling because the area of contact of steel backing and braking clamp body reduces.So the brake noise that can effectively avoid brake judder and cause because of bad connection.And, can the intensity of brake block not had any impact behind the fluting owing to frictional force when braking is horizontal direction.
The described commercial vehicle of the utility model comprises the automobile that is used to the personnel that transport and goods.
Description of drawings
Fig. 1 is the floor map of a kind of mode of execution of the utility model.
Fig. 2 is the worm's eye view of brake block steel back shown in Figure 1.
Embodiment
Disc brake pad like the commercial car of Fig. 1-shown in Figure 2 comprises steel backing 1 and the friction material 2 (friction material does not show fully) that fits with steel backing, and the lower support position of steel backing is provided with the groove 3 of two arches.Recess width is 10 mm, and the degree of depth is 3mm.
After two grooves are opened at the lower support position of steel backing,,, help the accumulation and the discharge of each brake back friction dust simultaneously at the contact segment slot milling because the area of contact of steel backing and braking clamp body reduces.So the brake noise that can effectively avoid brake judder and cause because of bad connection.And, can the intensity of brake block not had any impact behind the fluting owing to frictional force when braking is horizontal direction.
