An infinitely variable hydraulic drive for bicycles and other applications has a housing (11), attached side covers (65, 66), and a relatively movable displacement ring (32). The displacement ring carries a cylindrical pump ring (34) and a cylindrical motor ring (35). Vane rotors (30, 61) define the pump and motor of a hydrostatic transmission. Shift lever (20) allows the tube (59) to be rotated and thus permits lateral displacement of the displacement ring. Adjustment of the displacement ring controls pump and motor displacement to vary the transmission drive ratio. |
