Definitions
- the invention relates to a transmission, preferably an automatic transmission, with a Mauab and a vehicle with such a transmission.
- clutch-dependent Depending on where the power is split in the drive train, a distinction is made between clutch-dependent and engine-dependent power take-offs.
- the branch point is behind the starting clutch, i. In other words, a corresponding flow of power only takes place when the starting clutch is closed.
- the coupling of the power take-off usually takes place on the countershaft of the main gear or transmission, which has the disadvantage that the transmission and in particular the synchronizers are additionally stressed due to this connection.
- the distribution point for the power flow is on the engine side of the clutch. The power take-off is therefore independent of the frictional connection of the starting clutch. Since in these cases the power flow is not routed via the main or transmission gearbox, engine-dependent power take-offs can generally achieve higher power flows than clutch-dependent power take-offs.
- the central idea of the invention is to enable a variability of the attachment of the auxiliary unit along the longitudinal direction of the transmission via a corresponding extension shaft of the power take-off on the one hand and, on the other hand, via a parallel offset arranged at the end of the power take-off - usually not available - an additional possibility of Provide variation of the attachment of the auxiliary unit perpendicular to the longitudinal direction of the transmission.

- the transmission gear should here - according to the usual understanding - be designed for a speed and torque conversion between input and output, for which forms known in the prior art (including, for example, toothed gears, chain gears and / or hydraulic cal gears) can be used.
- the transmission should include a power take-off that can be connected to at least one auxiliary unit of the vehicle.
- a power take-off is understood to mean an interface via which power can be diverted from the actual drive train of the vehicle.
- the power take-off is preferably an engine-dependent power take-off.
- the power branching point for the power take-off can be arranged on the engine side or on the drive side and have no direct connection to parts of the reduction gear.
- the auxiliary output should in the present case comprise an extension shaft, preferably axially parallel to the drive and / or output.
- the extension shaft can be connected to the drive at a first shaft end via a first parallel offset and have a second parallel offset at a second shaft end.
- a “parallel offset” is intended to denote a displacement or a distance between two, preferably parallel, axes of rotation in a plane perpendicular to the two axes of rotation.
- the first and / or the second parallel offset, for. B. be designed as several intermeshing gears, in addition or alternatively other displacement techniques known in the prior art such. B. chain and / or belt connections can be used.
- the aforementioned transmission thus has a total of several "degrees of freedom" for possible - z. B. dependent on the available space in the vehicle - variations or adjustments of an auxiliary unit connection position on the power take-off.
- z. B. by means of the first parallel offset a "first”, z. B. lateral, shifting perpendicular to the drive or to the drive shaft.
- a “second” shift along the longitudinal direction of the gearbox and a “third”, e.g. B. vertical, shifting perpendicular to the axis of rotation of the extension shaft.
- the first shaft end and / or the first parallel offset can be arranged on the gear drive side in front of the transmission gear.
- the first shaft end and / or the first parallel offset can have a smaller distance from the drive and / or from a drive machine usually connected to the drive than the transmission gear.
- the second Shaft end and / or the second parallel offset can also be arranged on the transmission output side behind the reduction gear.
- the second shaft end and / or the second parallel offset can be arranged downstream of the transmission gear with respect to a gearbox longitudinal direction L (see FIGS. 1A and 1B) fixed by the axis of rotation of the drive and / or output.
- the area of the transmission can be dealt with with the power take-off and the connection point for at least one auxiliary unit on the power take-off can be relocated to the area on the transmission output side, in which more space is usually available to accommodate the auxiliary unit.
- the extension shaft of the power take-off can have a greater length extension than the transmission gear.
- the extension shaft - preferably in the transmission longitudinal direction L - be formed longer than the transmission gear.
- the extension shaft can also extend beyond the transmission gear on the transmission output side.

Primarily, the implementation of different power take-off configurations and thus possible accessory connection positions through the interaction of the first and second parallel offsets 5bi and 5b 2 should be illustrated, which is why the components located within the transmission housing 8 and the power take-off housing 9 are shown explicitly was waived.
- the embodiment designated with a) in FIG. 2 corresponds to the representation of the embodiment in the longitudinal direction of the transmission L, shown in a side view in FIG. 1B, as shown in FIG. based on the normal installation position of the transmission 10 in the driving tool 20 - a horizontal shift (arrow I) of the torque transmission path, ie a shift in the transverse direction of the transmission Q., while the second parallel offset 5b 2 is a vertical shift (arrow II) of the torque transmission path "Upwards", ie a shift in gear height direction H, causes. As is also illustrated by the different lengths of arrows I and II, the two parallel offsets 5bi and 5bi also have different offset lengths.

- the two parallel offset sets 5bi and 5bi continue to have different offset lengths.
- the embodiment labeled c) ultimately also illustrates the case that a parallel offset causes an “oblique” shift in the torque transmission path, ie both a shift in the gear height direction and a lateral shift in the gear direction Q more easily.
- the first parallel offset 5bi again causes a horizontal shift (arrow I) of the torque transmission path, ie a shift in the transverse direction of the transmission Q.
- the second parallel offset 5b 2 causes, however, both a lateral Shift in the transverse direction of the transmission Q as well as a shift in the vertical direction of the transmission H, resulting in the overall shift indicated by the arrow II “laterally obliquely upward”.
- the second parallel offset 5b 2 here also has a longer offset length compared to cases a) and b). As illustrated by the examples mentioned above, the combined use of two parallel offsets thus advantageously enables flexible variation of the power take-off configuration and thus possible accessory connection positions depending on the application.
- FIG. 3 shows a schematic illustration of a vehicle 20 in side view according to an embodiment of the invention.
- the motor vehicle 20, which in the present case is only an example of an articulated vehicle, d. H. a combination of a tractor unit and a semi-trailer, is here to include a transmission 10, as described in this document be.
