Description

A new type of brake pad

Technical Field

The utility model relates to the technical field of brake pad bodies, in particular to a novel brake pad.

Background Art

Automobile brake pads, also called automobile brake leathers, refer to the friction materials fixed on the brake drum or brake disc that rotates with the wheel. The friction lining and friction pads bear external pressure, generating friction to achieve the purpose of vehicle deceleration. Automobile brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks. The steel plates must be coated to prevent rust. During the coating process, the SMT-4 furnace temperature tracker is used to detect the temperature distribution of the coating process to ensure quality.

When the brake pad is used for emergency braking of the car, the long-term friction between the brake pad and the brake disc will generate a large amount of heat in a short time. Existing brake pads usually adopt natural cooling method. Due to the limited contact area between the brake pad and the air, the cooling effect is relatively poor.

By adopting the above technical solution, when the driver steps on the brakes during the continuous driving of the vehicle and the temperature of the brake pad is high, the temperature of the brake pad body will be transferred to the heat sink through the heat conduction plate. After absorbing the heat, the heat sink will increase the contact area with the air through the transverse ventilation holes and the longitudinal ventilation holes, thereby improving the efficiency of heat release and the cooling efficiency of the brake pad body.

Furthermore, the transverse ventilation holes and the longitudinal ventilation holes are provided in plurality and are interconnected.

Furthermore, an annular dustproof net arranged around the heat sink is fixed to the bottom surface of the mounting plate, and the inner side of the annular dustproof net is in contact with the side wall of the heat sink and the side wall of the rubber layer.

By adopting the above technical solution and setting the annular dustproof net, the probability of debris entering the transverse ventilation holes and the longitudinal ventilation holes causing the air circulation in the ventilation holes to deteriorate and thus affecting the heat dissipation effect is reduced.

Furthermore, a support plate is fixed on the side wall of the brake pad body, a sound-absorbing layer is fixed on the bottom surface of the support plate, a second bolt is penetrated through the mounting plate and is clearance-matched with the mounting plate, and the end of the second bolt is threadedly connected to the support plate.

The tungsten carbide coating 11 improves the wear resistance of the brake pad body 1 and extends the service life of the brake pad. A heat sink 3 is arranged on the top of the heat conducting plate 2, and a first bolt 4 is arranged on the heat sink 3 to be gap-matched with the heat sink 3 and the heat conducting plate 2. A transverse ventilation hole 31 is arranged on the side wall of the heat sink 3, and a longitudinal ventilation hole 32 is arranged on the side wall of the heat sink 3 away from the transverse ventilation hole 31, and a plurality of transverse ventilation holes 31 and longitudinal ventilation holes 32 are arranged and connected to each other. The transverse ventilation holes 31 and the longitudinal ventilation holes 32 are connected to each other to improve the air circulation on the heat sink 3 and further improve the efficiency of heat release. The heat sink 3 is provided with a mounting plate 5, and a rubber layer 6 is fixedly mounted on the bottom surface of the mounting plate 5, and the bottom surface of the rubber layer 6 is in contact with the top surface of the heat sink 3.

The setting of the annular dustproof net 7 reduces the probability that the air circulation in the ventilation holes 31 and the longitudinal ventilation holes 32 enter the sundries, causing the air circulation in the ventilation holes to deteriorate, thereby affecting the heat dissipation effect. The mounting plate 5 is penetrated by a second bolt 9 that is clearance-matched with the mounting plate 5.
