    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: In a mechanism for driving motor vehicles having a synchromesh gearbox with a friction clutch for each of two power branches with at least four power shiftable speeds and consecutive speeds are alternatively present on each one of the two power branches. Each friction clutch is a wet disc clutch with its inner discs having continuous radial grooves for a cooling oil flow supplied from a bore in a shaft. A switch piston shuts off the flow of cooling oil when the friction clutch is disengaged or almost completely disengaged. A prestressed cup spring in a compensating cylinder serves as a strong return spring thereby accelerating disengagement or delaying engagement of the friction clutch. Corrugated spring rings, axially situated between the inner discs and radially within the outer discs, serve as additional return springs. The wet clutch operates as a dry clutch and only has a low torque when it is disengaged. A large flow of cooling oil flows to the friction clutch and cools it as it engages and when it is engaged. The wet friction clutch replaces a conventional dry friction clutch, especially when starting up the motor vehicle.

    摘要: In a power take-off a spring engages a hydraulically actuated clutch-activating pressure plate to force the same into a neutral position. In one embodiment of the invention a hydraulically operated spring-loaded piston for arresting the rotational motion of an output shaft engages the pressure plate upon shifting thereof into its neutral position and consequent uncoupling of the output shaft from an input or drive shaft. In another embodiment of the invention an annular friction disk slidably connected or splined to the output shaft for stopping the same is clamped between a brake housing and a hydraulically actuated piston. The pistons automatically retract under the action of respective springs upon shut-off of the vehicle engine driving the input shaft and energizing the hydraulic system actuating the plates and the pistons, whereby the angular position of the output shaft may be manually adjusted.
