摘要： In a non-finite speed ratio transmission device using a toroidal continuously variable transmission (2), a hydraulic cylinder (30) for driving a power roller (20) via a trunnion (23), a shift control valve (46) for controlling a supply direction of oil to an oil chambers (30A, 30B) of the hydraulic cylinder (30), and a precess cam (35) which feeds back a displacement of the power roller (20) to the shift control valve (46) so as to shut-off the flow of oil to and from the oil chambers (30A, 30B), are provided. The shift control valve (46) comprises a drain port (46J) which can be connected to the oil chamber (30A) and a drain port (46I) which can be connected to the oil chamber (30B). By providing a positive torque control valve (40) which controls the oil pressure of the drain port (46I), and a negative torque control valve (45) which controls the oil pressure of the drain port (46J), the shift control valve (46) controls a differential pressure &Dgr;P of the oil chambers (30A, 30B) from 0 to a line pressure PL when the speed ratio ic of the toroidal continuously variable transmission (2) is maintained in the vicinity of a geared neutral position GNP.

摘要： A torque coupling connects the secondary driving wheels of an automotive vehicle indirectly to the power unit of the vehicle through a variable torque coupling, while the primary driving wheels on the vehicle are connected directly to the power unit. The coupling compensates for variations in the angular velocity of the primary and secondary wheels while still transferring torque to the secondary wheels. The coupling includes a magnetic particle clutch organized about an axis and a planetary gear set organized about the same axis. The coupling has two paths through which the torque is transferred, one a mechanical path and the other a clutch path. Most of the torque is transferred through the mechanical path, while the clutch path accommodates for slippage and controls the proportion of torque delivered to the secondary wheels, with the control being solely dependent on the magnitude of the current directed through the clutch.

摘要翻译： 扭矩耦合通过可变转矩联接将机动车辆的辅助驱动轮间接地连接到车辆的动力单元，同时车辆上的主驱动轮直接连接到动力单元。 联轴器补偿主轮和副轮的角速度的变化，同时仍然将扭矩传递到次轮。 联轴器包括围绕轴线组织的磁粉离合器和围绕相同轴线组织的行星齿轮组。 联轴器具有两个转矩传递的路径，一个是机械路径，另一个是离合器路径。 大部分扭矩通过机械路径传递，而离合器路径容纳滑动并且控制传递到次级车轮的扭矩的比例，该控制仅取决于引导通过离合器的电流的大小。

摘要： A planetary gear transmission has two or more planetary gear sets in the gear train. Each planetary gear set comprises a sun gear mounted on a sun shaft with the sun gear engaging a plurality of planet gears mounted on a planet gear carrier with the plurality of planet gears engaging a ring gear mounted on the transmission housing. Each gear of the planetary gear transmission is a helical cut gear. Sun gears and/or ring gears are mounted for axial movement with respect to the transmission. Thrust imbalances on the sun gears and/or ring gears resulting from uneven loading and the helical cut result in sun gears and/or ring gears moving in the axial direction to eliminate the thrust imbalances and thereby resulting in equal loading or power sharing amongst the planetary gear sets.
