The variator (3) is connected with the planetary gear unit (4) and with the manual gear unit (9) in the area of a first shaft (14) and in the area of a second shaft (15). The variator (3) and the planetary gear unit (4) form a module (2) and are arranged on a common carrier plate (19).
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.

摘要:
A transmission device (1) for a vehicle with a variator (3), a planetary gear unit (4) and a gearshift transmission unit (9). The variator (3) has a length which is greater than a width and a depth of the variator (3). When the variator (3) is installed in position in the vehicle, the length of the variator (3) is orientated at least approximately diagonally to the length of the vehicle.
摘要:
A method and a device for controlling the slip of a tractor vehicle or the like, in which the drive wheel slip is determined and, if the actual slip is different from a specified nominal slip, the gear ratio of a controllable transmission in the drivetrain is adjusted in the direction of slip optimization. The transmission is a geared-neutral transmission whose output speed, at full drive power, can be adjusted to an extremely small value close to zero.
摘要:
The invention concerns a multi-step speed-change transmission. An intermediate transmission (9) is situated between an input group (7) and a main group (8). A double gear (28, 29) forms an additional overdrive. The speed-change transmission according to the invention is provided for use in motor vehicles utilized in agriculture or construction.
摘要:
A continuously variable transmission device (1) has a power split which takes place in the area of a sum planetary transmission (9). A first shaft (8) of the sum planetary transmission (9) can be brought into operational connection with a drive engine or machine (3). A second shaft (12) of the sum planetary transmission (9) can be connected, for continuous variation of the gear ratio, with an electric machine (36) which itself can be coupled with an electric energy source (38).
摘要:
A transmission device for a vehicle (1) having a variator (3), which is configured as a hydrostatic device, of a transverse axial construction that can be adjusted at least in the region of a pivot axis (11), a planetary gear set (4) and a manual gear unit (9). The orientation of the pivot axis (11) of the variator (3), following installation in the vehicle, at least approximately corresponds to the orientation of a vehicle vertical axis (16).
