ABSTRACT:
Coupling apparatus for rotatably coupling an input shaft to an output shaft includes an outer assembly having a pair of inner conic friction surfaces mounted for rotation with the input shaft, a pair of opposed annular piston members located within the outer assembly defining a space between them, each of the annular piston members being connected to the output shaft and one of a pair of friction elements having outer conic friction surfaces. A pressurized fluid is directed into the space between the annular piston members to move the same away from each other against the force of respective cup-shaped springs whereby the outer friction surfaces of the friction elements engage the inner friction surfaces of the outer assembly to engage the coupling. A pin-fork arrangement is utilized to interconnect the output shaft with each of the annular piston members in a manner such that the output shaft, which is mounted in a bearing housed within the outer assembly, can be centered with respect to the outer assembly.
