Abstract
The invention relates to a multi-gear transmission device, particularly a two-gear transmission device, for transferring a drive torque from an input side to an output side, which transmission device has at least two selectable gear ratios. The multi-gear transmission device further has a multi-stage clutch device, particularly a two-stage clutch device, with at least two different, selectable limit torques. According to the invention, the multi-stage transmission device has at least two preferably switchable translating gear pairs, and the multi-stage clutch device is included in the translating gear pairs.

A multi-gear transmission device in particular a two-gear transmission device, for transmitting a drive torque from an input side to an output side, comprising:
- at least two selectable gear ratios and a multi-stage clutch device, in particular a two-stage clutch device, that has at least two different selectable limit torques;
- and
- at least two preferably switchable transmission gear pairs, wherein the multi-stage clutch device is accommodated in the transmission gear pairs,
- wherein each of the at least two transmission gear pairs has a first transmission gear on a first transmission shaft constituting the input side of the multi-gear transmission device and a second transmission gear on a second transmission shaft constituting the output side, and
- wherein that the multi-stage clutch device has at least two clutch units, each of which includes an input wheel, which is embodied as a grooved bell that has a detent profile provided on an inner surface thereof, and each input wheel is respectively mounted in freely rotating fashion on the second transmission shaft.
A multi-gear transmission device, comprising:
- at least two selectable gear ratios and a multi-stage clutch device that has at least two different selectable limit torques;
- and
- at least two switchable transmission gear pairs,
- wherein the multi-stage clutch device is accommodated in the at least two transmission gear pairs,
- wherein the multi-stage clutch device includes a first clutch unit having a first limit torque and a second clutch unit having a second limit torque,
- wherein the multi-stage clutch device has a first operating state, in which the first clutch unit is engaged, and a second operating state, in which the second clutch unit is engaged, and
- wherein the multi-stage clutch device has a third operating state, in which both the first clutch unit and the second clutch unit are engaged.
