TITLE Two-Speed Clutch ABSTRACT OF THE DISCLOSURE A two-speed clutch is shown according to the preferred embodiment of the teachings of the present invention for the selective rotational relation of an input shaft with a first or second sheeve unit having different diameters. The first sheeve unit is rotatably mounted to the input shaft. The second sheeve unit is mounted to a housing in turn rotatably mounted to the input shaft. The clutch includes a friction disc which is located between and frictionally interrelates with the first sheeve unit or the housing. The housing includes a single, reciprocally mounted piston for moving the friction disc. Utilizing a two-speed clutch of the present invention eliminates the requirement of two separate and complete drive units as in prior techniques. Furthermore, since the housing performs multiple functions, i.e., rotatably mounts the second sheeve unit to the input, slidably mounts the piston, acts as the interface for the second sheeve unit with the friction disc, and other functions, the two-speed clutch of the present invention greatly reduces the number of parts and results in a simplicity of construction. Furthermore, the two-speed clutch of the present invention provides a relatively dust and other element free environment for the piston and splined interconnection of the interfacing friction disc with the input.
