Abstract:
This is achieved according to the present invention by a torque/power transfer device comprising a main frame, a driving member (2), a driven member (3), and at least two pulley systems. Each pulley system comprises at least one stationary pulley (11a, 11b), which is stationary relative to the main frame, at least one movable pulley, which is movable relative to the main frame, a first wire connected to the driving member (2) and running over the at least one stationary pulley and the at least one movable pulley and a second wire operatively connected to the at least one movable pulley at one end and to the driven member (3) at its other end, wherein the second wire is running via a stationary regulator. The first wire of each pulley system is connected to a common point of the driving member and the second wire of each pulley system is operatively connected to a common eccentric point of the driving member. The regulators and the driven member are arranged relative to each other so that a centre of rotation for the driven member is arranged on an imaginary first line between the regulators of the both pulley systems. The imaginary first line has an angle relative the horizontal plane determined based on the radius of the driven member and a distance between the centre of rotation and respective regulator.
