Abstract
A thermally balanced brake disc stack provides brake discs of greater mass at the center of the stack and of lesser mass at the opposite ends of the stack. The temperature of the high mass discs in the center of the stack will rise to a lower level than the thinner discs at the ends of the stack. However, the heat dissipation rate at the ends of the stack exceeds that at the center of such that all of the discs cool to a predetermined temperature concurrently.
Claims13
A thermally balanced brake disc stack, comprising:
- a plurality of stator discs;
- a plurality of rotor discs interleaved with said stator discs;
- a pressure plate at a first end of the stack;
- an end plate at a second end of the stack;
- and
- wherein a stator disc and a rotor disc at each of said first and second ends are thinner than said stator and rotor discs at a center portion of the stack such that, during braking operations employing the brake disc stack, said stator and rotor disc at each of said first and second ends will rise to higher temperatures and cool more quickly than said stator and rotor discs at said center portion of the stack.

A brake disc stack, comprising:
- a first rotor disc at a first end of the stack;
- a second rotor disc at a second end of the stack;
- a plurality of rotor discs at a center portion of the stack;
- a first stator disc at said first end of the stack;
- a second stator disc at said second end of the stack;
- a plurality of stator discs at said center portion of the stack;
- and
- wherein said rotor and stator discs are interleaved, said first and second rotor discs are thinner than said plurality of rotor discs, and said first and second pluralities of said stator discs are thinner than said plurality of said stator discs such that, during braking operations employing the brake disc stack, said first and second rotor discs and said first and second stator discs will rise to a higher temperature and cool more quickly than said plurality of rotor discs and said plurality of stator discs.
