Abstract
A pressure balanced brake disc stack provides brake discs of greater thickness at the ends and center of the stack and of a lesser thickness at the areas in between the centrally disposed disc and the discs at the end of the stack. The increased thickness of the discs at the end of the stack prevent deflection or distortion of those discs to more evenly distribute the braking pressure applied thereto throughout the stack so as to provide a higher braking coefficient. Additionally, the unique configuration of the brake stack allows for effective heat dissipation at the discs adjacent to the end discs of the stack.
Claims15
A pressure balanced brake disc stack, comprising:
- a plurality of rotor discs;
- a plurality of stator discs interleaved with said rotor discs;
- a pressure plate at a first end of said stack;
- an end plate at a second end of said stack;
- and
- wherein a rotor disc at each of said first and second ends is thicker than said stator and rotor discs adjacent thereto such that during braking operations employing said brake disc stack, said rotor disc at each of said first and second ends will deflect less and distribute pressure more uniformly through the stack than if said end rotor discs were as thin as said stator and rotor discs disposed adjacent thereto.
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 additional rotor discs disposed between said first and second ends;
- a plurality of stator discs disposed between said first and second ends;
- a first stator disc apart from said plurality of stator discs disposed between said plurality of rotor discs, wherein said rotor and stator discs are interleaved, said first and second rotor discs are thicker than said plurality of said rotor discs and said plurality of stator discs;
- and
- said first stator disc is thicker than said first and second rotor discs, such that during braking operations employing the brake disc stack, said first and second rotor discs will distribute pressure more evenly within the brake disc stack than if said first and second rotor discs were as thin as said plurality of rotor discs.
