Embodiment Construction
[0035] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0036] Such as Figure 1-4 As shown: this embodiment is a wear-resistant and noise-reducing semi-metallic brake pad, including a friction block 1, and two slots 6 are formed in the middle of the friction block 1. The slots 6 improve the heat dissipation effect of the brake pad, and can Effectively let the rainwater flow away along the slot 6, twelve anti-slip lines 7 are arranged on the upper surface of the friction block 1, see figure 1 , twelve anti-slip lines 7 form three sets of anti-slip lines, two slots 6 are located between two adjacent anti-slip lines, chamfers 8 are formed on both sides of the friction block 1, and the bottom of the friction block 1 An adhesive layer 2 is provided, and a backboard 3 is provided below the adhesive layer 2. Corresponding lugs 9 are formed on both sides of the backboard 3, and a gasket 4 is arranged under the b...

The invention discloses a wear-resistant and noise-reduction semimetal-based brake pad which comprises a friction block. Multiple open grooves are formed in the middle of the friction block, multipleanti-skid lines are arranged on the upper surface of the friction block, chamfers are formed on the two sides of the friction block correspondingly, a bonding layer is arranged below the friction block, and a back plate is arranged below the bonding layer. Corresponding supporting lugs are formed on the two sides of the back plate, a gasket is arranged below the back plate, multiple correspondingfixing holes are formed in the back plate and the gasket, multiple convex parts are formed on the lower surface of the back plate, and multiple concave parts corresponding to the convex parts on the lower surface of the back plate are formed on the upper surface of the base plate. A silencing plate is further arranged between the back plate and the gasket, multiple through holes are formed in thesilencing plate, the friction block, the bonding layer and the back plate form a bonding block, and the bonding block is in bolted connection with the gasket. The invention further discloses a preparation process of the wear-resisting and noise-reducing semimetal-based brake pad. The brake pad provided has high wear resistance and noise reduction performance.
Description
technical field [0001] The invention relates to a wear-resistant and noise-reducing semi-metallic brake pad and a preparation process thereof, belonging to the technical field of semi-metallic brake friction materials. Background technique [0002] Brake pads are also called brake pads. In the braking system of a car, brake pads are the most critical safety parts. The brake pads play a decisive role in the quality of all braking effects. Therefore, good brake pads are the protectors of people and cars. The working principle of the brake is mainly from friction. Using the friction between the brake pad and the brake disc (drum) and the tire and the ground, the kinetic energy of the vehicle is converted into heat energy after friction, and the car is stopped; a set of good and efficient brakes The system must be able to provide stable, sufficient and controllable braking force, and have good hydraulic transmission and heat dissipation capabilities, so as to ensure that the for...
