ABSTRACT:
An electro-mechanical power transmission equipment, consisting of casing (3–3d) and inside the casing (3–3d) the power transfer arrangement having the power-in-axle (1) and the power-out axle (8), and between them an electricity generating and torque-transferring main generator arrangement (17,20,21,22) rotated by the axle (1), and an electric motor arrangement (29,30,31,31) that rotates axle (8), and the incoming rotational power is divided by the first planetary gear set (e.g.2b,4,5,6,7) between power-out axle (8) and the electric power transmission. For enhanced process of electric power transmission the main generator arrangement (17,20,21,22) is equipped with a special combination of speed up gearing (12,13,14,15) and optional clutches (10,19/10,19b) which greatly increase the air gap velocity between the main generator's magnetic field producing elements (20,21), and that in the electric motor arrangement (29,30,31,32) the armature winding (32) and the rotor (30) are counter-revolving in relation to one another and between rotor (30) and power-out axle (8) is an additional, special reduction gear arrangement (24,25,26,27) transferring multiplied torque to the power-out axle (8) and that in the power transmission process all torques and counter-torques of both the generator arrangement (17,20,21,22) and the electric motor arrangement (29,30,31,32) are directed to rotate the power-out axle8in the intended direction of axle (8).
