Zusammenfassung:	The invention relates to a variable belt drive (10). There is a need for an improved variable belt drive (10). A variable belt drive (10) may include a non-rotating piston housing (12) which forms one or several, preferably three piston bores (14). A rotatable input shaft (16) may be coupled to a power source and may be supported by bearings (18, 20) in the piston housing (12). A first sheave (24) may be mounted for rotation with the shaft (16) and may be fixed axially to the shaft (16). A second sheave (26) may be mounted for rotation with the shaft (16) and may be slidable axially on the shaft (16). A piston (40) may be movable in each piston bore (14) in response to fluid pressure.
