Motor vehicle brake pads with good heat dissipation performance

Abstract

The invention discloses a motor vehicle brake pad with good heat dissipation performance, relates to the technical field of brake pads, and comprises sequentially connected friction pads, a heat insulation layer, a back plate and a sound-absorbing sheet, and one side of the heat insulation layer is provided with a cooling groove for cooling The notch of the groove is provided with a heat conducting sheet, the side of the back plate is provided with a cooling water tank, a driving mechanism is provided between the back plate and the cooling water tank, the driving mechanism includes a driving component and a control component, and a A first connecting pipe and a second connecting pipe, a first connecting pipe is provided between the driving assembly and the cooling tank, a second connecting pipe is provided between the control assembly and the cooling tank, the first connecting pipe, the second connecting pipe The pipe, the first communication pipe and the second communication pipe are all provided with a first one-way valve. The invention lowers the temperature of the friction plate through self-circulation, so that the temperature can be maintained within an acceptable range to work normally, avoiding the situation that the friction coefficient decreases due to excessive temperature of the friction plate, and does not need to be driven by external energy, which is energy-saving and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of brake pads, in particular to a motor vehicle brake pad with good heat dissipation performance. Background technique [0002] Brake pads are an important component of the braking system. When working, the rotor is stopped mainly by the friction between the brake pads and the brake disc. Therefore, when the brake pads are working, a lot of heat will be generated due to friction, and their temperature can even be as high as two to three hundred degrees Celsius. Usually, stopping in time after braking can prevent the brake pads from being overheated for a long time. However, if you encounter a long-distance downhill road, you need to use the brake pads continuously, which will cause the temperature of the brake pads to be too high for a long time. On the one hand, it will increase the internal stress of the brake pads and reduce its service life. Even continuing to heat up will cause the friction coefficient...
