Embodiment

[0039] see Figure 1 to Figure 5 , the brake disc in this embodiment is a preferred embodiment of the present invention, and specifically includes a friction disc 1 and a skeleton disc 2, wherein both the friction disc 1 and the skeleton disc 2 have a disc structure with an inner ring, and the inner rings of the two The size of the ring and the outer ring are the same, and the friction disc 1 is cold riveted with the skeleton disc 2 through the first rivet 41 made of copper or steel, and is fixedly connected with the wheel through the skeleton disc 2 .

[0040] see in conjunction Figure 6-8 The friction disc 1 is made of carbon-ceramic friction material with a thickness of 10mm-20mm. Both sides of the friction disc 1 are processed into flat surfaces. On the friction disc 1, there are first rivet holes 101 arranged in an annular array around the center of the friction disc. , the first rivet holes 101 are respectively distributed in two groups near the inner ring and outer ri...

Abstract

The invention discloses a lightweight brake wheel disk for high speed train, comprising a frictional disk made of carbon / ceramic frictional material and a framework disk of carbon-carbon composite material; the frictional disk and the framework disk are bonded to each other and fixedly connected through a rivet, and connected with a wheel through the framework disk. The brake disk is composed of the frictional disk made of carbon / ceramic material and the framework disk made of carbon-carbon material; the whole density is about one third of forged steel, and the wheel disk has obvious weight reducing effect of the brake system and better high temperature performance and brake efficiency; the lightweight brake wheel disk cannot be corroded in the high-concentration oxygen, and the brake performance is greatly improved, thus the carbon-ceramic brake disk can replace the service life of two steel brake disks, and the maintaining cost is greatly reduced.

Description

technical field [0001] The invention relates to a high-speed train brake disc, in particular to a composite material brake disc with lightweight and high-efficiency features for a high-speed train brake system. Background technique [0002] The braking system is a key system for the safety and emergency of high-speed trains. The high-speed train braking system is composed of brake pads, brake discs, brake calipers, brake cylinders and control systems. The brake cylinder makes the brake pads clamp the brake disc through the brake caliper, and relies on the friction between the brake pads and the brake disc to convert the kinetic energy of the high-speed train into heat energy, and the heat energy is dissipated into the atmosphere through the brake disc and brake pads, thereby achieve the purpose of braking. Traditional brake discs are mostly metal brake discs made of a single material, which is heavy, and due to manufacturing processes and other reasons, there will inevitab...
