Abstract: A full carbon-ceramic axle-mounted brake disc is disclosed, including a disc hub and a plurality of friction discs sleeved on the disc hub and coaxially stacked. The plurality of friction discs and the friction discs and the disc hub are locked and connected integrally through connecting structures. The friction discs are made of a carbon-ceramic composite material and are composed of heat dissipation reinforcing ribs arranged radially on a disc face and a back face, the heat dissipation reinforcing ribs between the stacked friction discs being in contact with each other on a one-to-one basis. Radial heat dissipation channels are formed on two sides of the heat dissipation reinforcing rib, and a connecting groove connecting the radial heat dissipation channels on the two sides is formed between the heat dissipation reinforcing ribs.

Abstract: A full carbon-ceramic axle-mounted brake disc is disclosed, including a disc hub (2) and a plurality of friction discs (1) sleeved on the disc hub (2) and coaxially stacked. The plurality of friction discs (1) and the friction discs (1) and the disc hub (2) are locked and connected integrally through connecting structures. The friction discs (1) are made of a carbon-ceramic composite material and are composed of heat dissipation reinforcing ribs (11) arranged radially on a disc face (10) and a back face, the heat dissipation reinforcing ribs (11) between the stacked friction discs being in contact with each other on a one-to-one basis. Radial heat dissipation channel (12) are formed on two sides of the heat dissipation reinforcing rib (11), and a connecting groove (13) connecting the radial heat dissipation channels (12) on the two sides is formed between the heat dissipation reinforcing ribs (11).
