    摘要: A continuously variable transmission device comprising a variator and a secondary power splitting. For power splitting, a planetary gear set has a first shaft coupled to the transmission input, a second shaft of the gear set coupled a first shaft of the variator, and a third shaft of the gear set couples a second shaft of the variator. First and second shift elements are provided to switch between first and second gear ratio ranges. Via the variator, the gear ratio is continuously variable within the gear ratio range and the two gear ratio ranges overlap. To implement the first gear ratio range, the second shaft of the gear set is connected, via the first shift element, to the transmission output, and to implement the second gear ratio range, the third shaft of the planetary gear set is connected, via the second shift element, to the transmission output.

    摘要: The gear-change transmission has a closely stepped input group (7) before a main group for fine tuning the speed within a working range. Between the input group (7) and the main group (8) is situated a pressurized-oil cooled drag-torque reducing multi-disc starting clutch (26) so that the gears in both groups can also be easily engaged when using synchronizer positive clutches (18, 20). A reversing shaft (13) for reverse gear is fully integrated in the input group (7) and its gear clutches (F/G) can be introduced with a gear selector (83, 112) the same as for the remaining splitter gears of the input group (7). A change-over clutch (36) for an intermediate transmission (9) is optionally placed directly before the starting clutch (26) operatively and structurally on the primary shaft (32) of the starting clutch (26). The main drive shaft (10) is guided parallel to the countershaft (12) and to the drive shaft (39) of the main group (8) through the common transmission housing (1) and is connectable, via a separating clutch (67) and via a two-step transmission group (68, 69, 70, 71, 72), with a power take off shaft (73). The input group (7), with the same arrangement of the shafts (11, 12, 13), can be equipped either with hydraulic double gear clutches (A, B, C, D, F, G) axially aligned in respect to each other or with double synchronizer clutches. In the first case, there is provided over the main group (8) on the main drive shaft (10), a change-over clutch (25) for a mechanical bypass operative connection of the powershift clutches (14, 15, 16) utilizable in forward or reverse direction for towing or emergency possibilities.
