Abstract
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.
Claims16
Controlled hydraulic transmission containing housing, caps, two shafts, control unit and rotary mechanism of interaction with power fluid, characterized in that between cap and piston of rotary mechanism is installed gear transmission.
A controlled hydraulic transmission containing housing with opening for control arm fixed on internal mechanism of rotary movement transformation and internal cavity filled with power fluid and said mechanism of rotational movement transformation;
- caps, which internal face is machined to assure sliding contact with the piston face, the caps having hole for supporting thru shaft;
- and two shafts, characterized in that the shafts are provided with cam having cylindrical surface eccentric against the shaft axis with eccentricity e and intended for running fit of the piston.
