(54) VARIABLE HYDRAULIC TRANSMISSION


(57) The invention refers to hydraulic rotation transmissions and can be used in power transmissions and transmissions where the stepless ratio variation is essential. It can also be used as stepless speed transmission for vehicles (Fig. 1). Getting any transmission ratio with higher performance factor is achieved by applying in the hydraulic transmission new scheme, including motionless and movable bodies containing two coupled rotors, composing of camshafts with pistons and separated by motionless wall. Transmission ratio varies from 0 to maximal value displacing the movable body in axial direction by means of overhanging control arm.
