Embodiment Construction

[0011] The present invention will be further described below in conjunction with accompanying drawing:

[0012] Such as figure 1 As shown, the present invention relates to a high-speed train brake disc-wheel disc, comprising a brake disc body 1, a brake friction surface 2, a center positioning hole 3, uniformly distributed mounting holes 4, a reinforcing boss 5, a first radial Plate-shaped cooling ribs 6 , second radial fan-shaped cooling ribs transition balance boss 7 , third radial plate-shaped fan-shaped combined cooling ribs 8 , transition balance boss 9 . It is characterized in that: the central positioning hole 3 of the high-speed train brake disc body 1 is positioned on the brake assembly device, connected by bolts through the uniformly distributed installation holes 4, and the uniformly distributed installation holes 4 are distributed on the reinforcing boss 5. The heat generated during the friction process of the braking friction surface 2 is dissipated through the r...

Abstract

The invention relates to a high-speed train brake disc-a wheel disc. The high-speed train brake disc is composed of a brake disc body, a brake friction surface, a central positioning hole, uniformly-distributed mounting holes, a reinforcing boss, radial radiating ribs and a transition balancing boss; and the brake disc is characterized in that the central positioning hole of the high-speed train brake disc body is positioned on a high-speed train wheel, the central positioning hole and the high-speed train wheel are connected by bolts through the uniformly-distributed mounting holes, and the uniformly-distributed mounting holes are distributed on the reinforcing boss. Heat generated in the braking friction process is dispersed through the radial radiating ribs, and the generated vibrationis eliminated through the transition balancing boss; and the brake disc has the advantages of being good in heat dissipation effect, high in braking strength, stable in braking operation and high in safety and effectiveness.

Description

technical field [0001] The invention relates to a high-speed train brake disc, in particular to a high-speed train brake disc-wheel disc. Background technique [0002] As we all know, disc brakes are the basic braking method for high-speed trains to stop at present. With the increase of the running speed of the train, the braking safety requirements will also be greatly improved. During the braking process of the train, higher temperature and greater vibration will inevitably affect the braking effect. Higher temperature and greater vibration will inevitably Affect the safety of high-speed trains. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the above-mentioned prior art, and provide a high-speed train brake disc-wheel disc structure with the advantages of good heat dissipation effect, high braking strength, stable braking operation, and high safety and effectiveness. . [0004] The tec...
