ABSTRACT:
A cushioned brake assembly for dampening the reaction forces between rotating and non-rotating components of the brake assembly during a breaking action, includes a plurality of alternating rotatable and non-rotatable discs, a fluid actuated piston, a spring element, and a cushion disc positioned between the piston and the discs. The cushion disc includes a resilient portion which is compressed during a braking action to dampen the reaction forces. Prior art clutch and brake assemblies utilize various types of spring elements to dampen reaction forces between rotating and non-rotating components during clutching and braking. These prior art dampening elements do not provide optimum damping functions. The subject cushioned brake assembly provides optimum spring rate characteristics during cushioned braking function.
