Abstract
Abstract A coupling assembly which may be utilized as a brake, torque convertor or differential. The basic assembly includes a pair of concentric cylindrical members with roller elements disposed therebetween and in rolling engagement with the concentric members. Normally one concentric member may be freely driven or rotated relative to the other, however, the system also includes actuation means for distorting one of the concentric members into an elliptical or other configuration to provide a distortion in the other member which moves therealong in a wave-like fashion, the transmission of energy between the members being proportional to the amount of distortion, i.e., the number or frequency of distortions or the amplitude of a single distortion or various combinations thereof.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
94 words
A coupling assembly comprising: output means, input means freely movable relative to said output means in a deactuated condition and non-movable relative to said output means in a fully actuated condition, and actuation means for variably distorting a portion of one of said output and input means into the other so that the latter has a distortion which moves therealong in wave-like fashion between said deactuated and actuated conditions whereby the transmission of energy from said input means to said output means is proportional to the amount of said distortion in said output means.
Claim 2
Dependent Claim
94 words
A coupling assembly comprising: output means, input means freely movable relative to said output means in a deactuated condition and non-movable relative to said output means in a fully actuated condition, and actuation means for variably distorting a portion of one of said output and input means into the other so that the latter has a distortion which moves therealong in wave-like fashion between said deactuated and actuated conditions whereby the transmission of energy from said input means to said output means is proportional to the amount of said distortion in said output means.
Claim 3
Dependent Claim
95 words
A coupling assembly comprising: output means, input means freely movable relative to said output means during a deactuated condition and increasingly less movable relative to said output means between said deactuated condition and a fully actuated condition, and actuation means to variably distort said output and input means for providing a distortion in said output means which moves therealong in wave-like fashion of decreasing velcoity from said deactuated condition to said actuated condition so that transmission of energy from said input means to said output meaNs is proportional to said distortion in said output means.
Claim 4
Dependent Claim
95 words
A coupling assembly comprising: output means, input means freely movable relative to said output means during a deactuated condition and increasingly less movable relative to said output means between said deactuated condition and a fully actuated condition, and actuation means to variably distort said output and input means for providing a distortion in said output means which moves therealong in wave-like fashion of decreasing velcoity from said deactuated condition to said actuated condition so that transmission of energy from said input means to said output meaNs is proportional to said distortion in said output means.
