FULL CARBON-CERAMIC AXLE-MOUNTED BRAKE DISC

摘要

A full carbon-ceramic axle-mounted brake disc, comprising a disc hub (2) and a plurality of friction discs (1) coaxially stacked on the disc hub (2); the plurality of friction discs (1) and the friction discs (1) and the disc hub (1) are locked and connected integrally by means of a connecting structure; the friction discs (1) are a carbon-ceramic composite material, and are composed of heat dissipation reinforcing ribs (11) arranged radially on a back face and a disc face (10), the heat dissipation reinforcing ribs (11) between stacked friction discs being in contact on a one-to-one basis; a radial heat dissipation channel (12) is formed on both sides of the heat dissipation reinforcing ribs (11), and a connecting channel (13) connecting the radial heat dissipation channels on both sides is formed between the heat dissipation reinforcing ribs (11). The present full carbon-ceramic axle-mounted brake disc has the advantages of a simple structure, excellent heat dissipation effects, reliable connection, high structural strength, convenient maintenance, and light weight, and reduces the energy consumption and maintenance costs of a transport vehicle whilst ensuring reliable braking.
