Problems solved by technology
Now the best performance of the friction block is ceramic material, but the price is relatively expensive. In the city, the brakes are lightly stepped on or tapped to slow down. Only when the speed is fast and the distance is close can the heavy step be used. The price of replacing the whole ceramic friction block is relatively Expensive, and the existing brake pads are easy to accumulate dust, which reduces the friction coefficient of the brake pads. The thickness of the friction layer on the brake pads has certain requirements. Too thin will affect the sensitivity of the brakes and reduce the safety performance.

The invention provides a brake pad. The brake pad comprises a metallic base plate. Installing ports are formed in the two sides of the metallic base plate. A rectangular groove is formed in the middle of the metallic base plate. The size of the groove is identical with that of a fixed plate. Screw through holes are formed in the groove. Cylindrical hole grooves corresponding to the through holes in the groove are formed in the fixed plate. Threads matched with screws are arranged in the hole grooves. A connecting plate is connected with the fixed plate through springs. The fixed plate is connected to the metallic base plate through threads. A semimetal friction block is arranged on the connecting plate. A ceramic friction block is arranged on the metallic base plate and surrounds the semimetal friction block. A chip discharging groove is formed in the ceramic friction block. Since the brake pad is provided with the chip discharging groove, the brake pad has good heat dissipation and chip discharging effects; and the semimetal friction block protrudes out of the ceramic friction block by 5 mm, the semimetal friction block makes contact with a brake disc to reduce the speed by only slightly stepping on the semimetal friction block, and the semimetal friction block has a larger number of working times, and the service life of the ceramic friction block is guaranteed to the maximum extent.
Description
technical field [0001] The invention belongs to parts of an automobile brake system, in particular to a brake pad. Background technique [0002] In the braking system of a car, the brake pads are the most critical safety parts. The brake pads play a decisive role in the quality of all braking effects. When braking, the friction blocks are squeezed on the brake disc or drum to generate friction, thus To achieve the purpose of vehicle deceleration and braking. Now the best performance of the friction block is ceramic material, but the price is relatively expensive. In the city, the brakes are lightly stepped on or tapped to slow down. Only when the speed is fast and the distance is close can the heavy step be used. The price of replacing the whole ceramic friction block is relatively Expensive, and the existing brake pads are easy to accumulate dust, which reduces the friction coefficient of the brake pads. The thickness of the friction layer on the brake pads has certain req...
