Description

Technical Field

[0001] The utility model relates to the technical field of brake pads, in particular to a heat dissipation type brake pad. Background Art

[0002] At present, brake pads are also called brake leathers. In the braking system of a car, brake pads are the most critical safety parts. The quality of all braking effects is determined by brake pads, so good brake pads are the protectors of people and cars. Brake pads are generally composed of steel plates, adhesive insulation layers and friction blocks.

[0003] A heat dissipation brake pad is disclosed in a Chinese utility model patent with announcement number CN211715600U, including a friction member, a heat sink A is fixedly connected to the bottom of the friction member, a heat sink B, a heat insulation layer and a base are arranged in sequence below the heat sink A, a short cylinder is arranged at the bottom of the heat sink A, a plurality of cylindrical grooves are arranged at the top of the heat sink B, the depth of the cylindrical groove is 1 / 3 of the length of the short cylinder, the bottom end of the short cylinder is inserted into the cylindrical groove, a filter screen is covered between the outer walls of the heat sinks A and B, a plurality of pairs of protrusion groups are arranged on the outer walls of the heat sinks A and B, heat dissipation fins are straddled between the protrusion groups, and two screws are also arranged at the bottom of the heat sink A, which pass through the heat sink B, the heat insulation layer and the base in sequence and pass out from the bottom of the base to be threadedly connected with a nut.

[0004] Although the above-mentioned prior art has good ventilation and heat dissipation effects, a large amount of heat will be generated during the friction of the brake pad, causing the temperature of the brake pad to rise sharply. The heat dissipation efficiency is low if the heat is only dissipated by the heat dissipation holes of the brake pad. If the temperature drops slowly, it is easy to accelerate the wear of the brake pad and the brake disc, reducing the service life. Utility Model Content

[0005] In order to solve the technical problem that the heat dissipation efficiency is low and the temperature drops slowly, the wear of the brake pad and the brake disc is likely to be accelerated and the service life is reduced, the utility model provides a heat dissipation type brake pad.

[0006] The utility model is implemented by the following technical scheme: a heat dissipation type brake pad, comprising a fixing plate, a base plate is fixedly mounted on the fixing plate by fastening screws, a friction plate is fixedly connected to the top of the base plate by a heat-conducting adhesive layer, and a heat dissipation component is arranged between the base plate and the fixing plate for rapid heat dissipation of the friction plate when in use.

[0007] As a further improvement of the above scheme, the heat dissipation assembly includes a heat dissipation cavity opened on the lower surface of the substrate, the lower surface of the heat dissipation cavity is fixedly connected to a plurality of mounting plates, the bottom of the mounting plate is fixedly connected to a plurality of rotating shafts, and the surface of the rotating shaft is rotatably connected to fan blades.

[0008] Through the above technical solution, when the car is driving, the fan blades are rotated by the wind. When the brake pads are applied, the heat generated is quickly dissipated through the rotation of the fan blades. Even when the car is parked, the fan blades will rotate for a period of time to dissipate heat, thereby speeding up work efficiency.

[0009] As a further improvement of the above solution, a copper heat sink is provided on the upper surface of the fixing plate, and the heat sink is provided corresponding to the fan blades.

[0010] As a further improvement of the above solution, a plurality of heat dissipation grooves are separated on the top of the friction plate, and a plurality of heat dissipation holes penetrate the interior of the friction plate.

[0011] Through the above technical solution, the use of heat dissipation slots and heat dissipation holes can further accelerate the heat dissipation speed.

[0012] As a further improvement of the above solution, a pad is provided between the fixing plate and the base plate, the pad is elliptical in shape, and is used to increase the distance between the fixing plate and the base plate, thereby accelerating the air flow rate.

[0013] Through the above technical solution, by increasing the distance between the fixing plate and the base plate, the convection space is enlarged, and the surrounding air flow rate is increased, thereby achieving the purpose of rapid heat dissipation.

[0014] As a further improvement of the above solution, the fan blades are rotated by air blowing during the driving of the vehicle, so that the brake disc automatically dissipates heat while working.

[0015] Through the above technical solution, the fan blades can rotate automatically without a driving device when the car is running, thus saving energy loss.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] When the vehicle brakes, the friction plate rubs against the brake disc to slow down the brake. The fan blades are rotated by the air during the driving of the vehicle. The heat generated is quickly dissipated through the rotation of the fan blades. Even when the vehicle is parked, the fan blades will rotate for a period of time to dissipate heat. This design quickly dissipates the heat of the brake pads through the automatic rotation of the fan blades, thereby speeding up work efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] When the car is driving, the fan blades 12 are rotated by the wind. When the brake pads are applied, the heat generated is quickly dissipated through the rotation of the fan blades 12.
