Abstract
A transmission arrangement, particularly for an agricultural working vehicle, has a parallel-shift transmission and an input shaft, proceeding from which input shaft a drive power can be distributed via a first and a second shifting element to respective layshafts, and has a first and a second coaxially arranged output shaft, wherein the drive power can be transmitted by each of the layshafts to each of the output shafts as needed, and has a group-shift transmission with multiple shifting groups.
Claims9
A transmission arrangement for an agricultural working vehicle, comprising:
- a parallel-shift transmission having an input shaft, from which a drive power is distributed via a first shifting element and a second shifting element to a respective first layshaft and a second layshaft, and having a first output shaft and a second output shaft arranged coaxially with one another, wherein the drive power can be transmitted from each of the layshafts to each of the output shafts as necessary;
- a first shifting point having a first position which connects the first layshaft to the first output shaft and a second position which connects the first layshaft to the second output shaft, and a second shifting point having a first position which connects the second layshaft to the first output shaft and a second position which connects the second layshaft to the second output shaft;
- a group-shift transmission having multiple shifting groups axially spaced from the first layshaft and the second layshaft, wherein a first shifting group is drivingly connected to the first output shaft and a second shifting group is drivingly connected to the second output shaft, the multiple shifting groups transmitting drive power to a final output shaft;
- and
- a third shifting point having a first position which connects the first output shaft to the final output shaft via the first shifting group and a second position which connects the first output shaft to the second output shaft, and a fourth shifting point having a first position which connects the second output shaft to the final output shaft via the second shifting group.
