Description

Technical Field

[0001] The utility model relates to the technical field of automobile brake pads, in particular to an automobile brake pad which is convenient for heat dissipation. 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. Existing brake pads will generate high temperatures when braking, which can easily cause the brake pads to deform and affect their service life.

[0003] After searching, the application with patent number CN212455277U discloses a car brake pad that is easy to dissipate heat, including a back plate and a friction plate arranged on the back plate, wherein a plurality of heat dissipation channels are arranged in the friction plate, and the heat dissipation channels are inclined downward in the vertical direction. The heat dissipation channels penetrate the friction plate and are provided with an air inlet at the downward end and an air outlet at the upward end. A cooling fan is provided at one end of the air inlet, so that the brake pad can be cooled to prevent deformation of the brake pad caused by high temperature and affect the service life of the brake pad.

[0004] However, due to the setting of the heat dissipation channel and the heat dissipation fan, the friction plate is directly cooled by the heat dissipation fan, and the heat generated by the friction plate is carried away by the flowing wind, resulting in that the heat generated by the friction plate cannot be discharged in time, and the heat dissipation effect is poor. At the same time, due to the setting of the back plate and the friction plate, the friction plate will produce friction noise and vibration when in use, the noise is loud, the impact on the environment is great, it is easy to cause noise pollution, and the practicality is low.

[0005] Therefore, we propose an automobile brake pad that is easy to dissipate heat. Utility Model Content
