All-carbon ceramic axle-mounted brake disc

Abstract

The invention discloses an all-carbon ceramic axle-mounted brake disc. The brake disc includes a disc hub and a plurality of friction discs which are coaxially piled up, wherein the disc hub is sleeved with the friction discs. The friction discs are interlocked and connected through connecting structures into a whole and the friction discs and the disc hub are also interlocked and connected through connecting structures into a whole; the friction discs are made from carbon ceramic composite materials and composed of heat dissipation reinforcement bars with the disc surfaces and the rear surfaces are arranged in the radial direction, the heat dissipation reinforcement bars between the piled-up friction discs make contact in a one-to-one corresponding mode, axial heat dissipation channels are formed in the two sides of the heat dissipation reinforcement bars, and communication grooves communicated with the axial heat dissipation channels on the two sides are formed between the heat dissipation reinforcement bars. The all-carbon ceramic axle-mounted brake disc has the advantages that the structure is simple, the heat dissipation effect is excellent, connection is reliable, maintenanceis convenient, and the weight is low, and reliable braking is ensured while the energy consumption and maintenance cost of a transport tool are reduced.

Description

technical field [0001] The invention belongs to the braking technology of vehicles (including trains, automobiles and heavy-duty trucks, etc.), and in particular relates to an all-carbon ceramic axle-mounted brake disc. Background technique [0002] The brake disc is a key component of the vehicle, which is related to the safety of the vehicle. Because of the complex and harsh working environment and inconvenient maintenance and replacement, the brake disc product must have reliable braking, convenient maintenance and a long service life. At present, the brake discs used in vehicles are generally made of metal materials such as cast steel (iron) or forged steel, which have the characteristics of high technical maturity, low cost, and wide applicable speed range, and have been widely used at home and abroad. However, traditional cast steel (iron) or forged steel brake discs are heavy, which is not only inconvenient for installation and maintenance, but also increases the ener...

AI Technical Summary

Problems solved by technology

[0004] At present, most of the structural design of brake discs is aimed at metal brake discs, and its heat dissipation structure is usually made of integral casting, so it is not suitable for carbon ceramic brake discs

However, reports on carbon-ceramic brake discs are generally limited to the manufacturing process of the disc, and do not involve specific structural design.
