Abstract

A transmission includes a drive element, a first output element, a primary transmission unit, a reversing unit, and an intermediate gearbox. At least two of the at least nine shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least four shifting elements so as to establish at least twenty-eight forward gears between the drive element and the first output element.

First claim

What is claimed is:

1. A transmission for transmitting a torque generated by a traction motor to at least one driven axle of an agricultural or industrial commercial vehicle, the transmission comprising:
a drive element;
a first output element;
a primary transmission unit including at least one first planetary gear set having a first sun gear, a first ring gear, a first planet carrier, and a first planet set, and a second planetary gear set having a second sun gear, and a third planetary gear set having a third sun gear and a third planet set, and wherein the second planetary gear set and the third planetary gear set have a first common planet set and a first common ring gear and a first common planet carrier, and the primary transmission unit includes at least nine shifting elements;
a reversing unit having at least two shifting elements; and
an intermediate gearbox having at least two shifting elements;
wherein at least two of the at least nine shifting elements of the primary transmission unit, at least one of the at least two shifting elements of the reversing unit, and at least one of the at least two shifting elements of the intermediate gearbox are activatable in combinations of at least four shifting elements so as to establish at least twenty-eight forward gears between the drive element and the first output element.

2. The transmission of claim 1 , wherein the intermediate gearbox is disposed in the direction of the force flux and torque flux downstream of the primary transmission unit and upstream of the reversing unit.

3. The transmission of claim 1 , wherein the reversing unit is disposed in the direction of the force flux and torque flux downstream of the primary transmission unit and upstream of the intermediate gearbox.

4. The transmission of claim 1 , wherein the at least nine shifting elements of the primary transmission unit include a first brake, a second brake, a first clutch, a second clutch, a third clutch, a fourth clutch, a fifth clutch, a sixth clutch, and a seventh clutch.

5. The transmission of claim 1 , wherein the reversing unit includes a fourth planetary gear set having a fourth sun gear, a fourth ring gear, a fourth planet carrier, and a fourth planet set.

6. The transmission of claim 1 , wherein the intermediate gearbox includes a fifth planetary gear set having a fifth sun gear, a fifth ring gear, a fifth planet carrier, and a fifth planet set.

7. The transmission of claim 1 , wherein the at least two shifting elements of the reversing unit include an eighth clutch and a third brake.

8. The transmission of claim 1 , wherein the at least two shifting elements of the intermediate gearbox include a ninth clutch and a tenth clutch.

9. The transmission of claim 1 , further comprising a power take-off module.

10. The transmission of claim 9 , further comprising a rear axle module disposed between the power take-off module and the primary transmission unit.

11. The transmission of claim 9 , further comprising a power take-off drive shaft.

12. The transmission of claim 1 , wherein the first output element is connected in a drivable manner to a second intermediate element.

13. An agricultural or commercial vehicle comprising the transmission of claim 1 .

14. The agricultural or commercial vehicle of claim 13 , wherein the transmission is disposed in the vehicle in such a manner that a transmission longitudinal axis is substantially parallel to a vehicle longitudinal axis.
