Abstract
Abstract A clutch brake for use with non-synchronized vehicle transmissions includes noise suppression components. The clutch brake comprises a pair of housing members secured together which receive components of a torque limiting assembly. The assembly includes an inner ring member adapted to rotationally engage the transmission drive shaft and which is coupled to a concentric, outer ring member through a lost motion coupling. The outer ring, in turn, is frictionally coupled to the housing by an adjacent wave spring which includes inwardly directed tabs. The tabs exert a biasing force against the inner ring member, inhibiting wholly unrestricted motion which might generate undesirable vibration and noise.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
71 words
In a clutch brake assembly having a housing with opposed friction surfaces, a first ring member secured for rotation with a drive shaft, a second ring member rotationally coupled to said first ring member through a lost motion coupling and an axially resilient member disposed between said housing and said second ring member, the improvement comprising tab means extending from said axially resilient member for axially biasing said first ring member.
Claim 2
Dependent Claim
71 words
In a clutch brake assembly having a housing with opposed friction surfaces, a first ring member secured for rotation with a drive shaft, a second ring member rotationally coupled to said first ring member through a lost motion coupling and an axially resilient member disposed between said housing and said second ring member, the improvement comprising tab means extending from said axially resilient member for axially biasing said first ring member.
