Example Embodiment
[0050] Example one
[0051] A high-speed train brake pad with optimized friction particle combination and installation method. The brake pad includes a brake disc 1, a brake pad structure and a loading device. The loading device is connected to the brake pad structure, and the brake pad structure is connected to the brake pad structure. The brake disc 1 is matched, and the brake pad structure includes a brake pad back plate 2. The brake pad back plate 2 is provided with a plurality of friction particles 7, and the plurality of friction particles 7 have two types and The above shape. In this embodiment, the structure of the brake pad back plate 2 is symmetrical, the shape is arc-like, and it is stamped and formed by steel materials.
[0052] The friction particles 7 include polygonal friction particles 702 and circular friction particles 701. In this embodiment, the polygonal friction particles 702 are regular hexagonal friction particles.
[0053] Studies have shown that the perfo...
Example Embodiment
[0063] Example two
[0064] The technical solution of this embodiment is basically the same as that of the first embodiment, the difference lies in:
[0065] Such as figure 2 As shown, in this embodiment, the number of friction particles 7 is eighteen, ten of which are circular friction particles 701, and the remaining eight are regular hexagonal friction particles 702. The ten circular friction particles 701 are arranged on the outer layer and the cut-in end of the brake pad back plate 2 with relatively high relative speed and impact; the eight regular hexagonal friction particles 702 are arranged on the system with relatively low relative velocity and impact. The inner and middle part of the back plate 2 of the moving brake disc. Due to the large passenger flow in the city, excessive braking noise will seriously affect the passenger's riding experience, so the high-speed trains operating in the city put forward higher requirements for the vibration and noise reduction of the br...
