Technical Field

[0001] The utility model relates to the technical field of friction materials, in particular to a friction plate with a bearing structure. Background Art

[0002] With the continuous development of construction, electric power and engineering machinery, the application and demand of loaders are also growing. Loaders are used in bulk material working conditions in ports, construction sites, gravel plants, timber yards and other places. Indeed, loaders are a main force in developing China. In actual use, existing domestic friction plates still have problems such as unstable friction performance, high wear rate and low heat resistance, which seriously restrict the excellent maneuverability of the mechanical system. Especially under heavy load and high energy load conditions in the port field, the performance stability of the friction pair is more important.

[0003] Therefore, it is urgent and necessary to develop new friction plates and friction pairs that match the transmission system or brake system, have a long service life and high reliability. Copper-based powder metallurgy friction materials are powder metallurgy materials prepared by powder metallurgy with copper alloy as the matrix, lubricating components and friction components added.

[0004] Since copper has high thermal conductivity and good wear resistance, copper-based friction materials have the characteristics of good thermal conductivity, stable friction coefficient, wear resistance, and excellent heat resistance. Compared with iron-based materials, they have the advantage of low wear with mating parts (cast iron or steel), especially in wet working conditions, they have high wear resistance and corrosion resistance.

[0005] At present, my country's high-speed train brake pads are mainly imported. Domestic brake pad materials have the characteristics of low friction coefficient and high wear rate, which cannot meet the development needs of my country's high-speed trains. The country attaches great importance to friction materials used in high-speed and heavy-load conditions and their development prospects. Summary of the invention
