Torque converter based on erf and / or magnetoviscous fluids

摘要

The drive and driven sides of the torque converter (1)have an hydraulic positive-displacement pump (2) with a first (5) and second (6) rotor each of which has at least one rotary piston protruding into a respectively electro-rheological and electro-rheological/magneto-rheological fluid-filled chamber (8,20) in the housing (4). Separately electrically controlled condenser plate segments and/or coil arrangements (10,22) are distributed over the periphery of the two end walls (9,21). The pressure side of the positive-displacement pump is connected to the entry side of the positive-displacement motor (3).
