Abstract

Harvesting vehicle, in particular forage harvester or combine harvester, comprising a mounting frame ( 10 ), wherein the mounting fame ( 10 ) is designed to couple an attachment to the mounting frame ( 10 ) and via the mounting frame ( 10 ) to the harvesting vehicle, and comprising a drive coupler ( 16 ) which engages with the mounting frame ( 10 ) and which is designed to form a drive connection between the attachment and the harvesting vehicle in order to transmit a drive power provided by the harvesting vehicle in the direction of the attachment, wherein the drive coupler ( 16 ) has a drive hub ( 17 ) which can be coupled to the harvesting vehicle, a coupling disk ( 19 ) which can be coupled to the attachment and a centering mandrel ( 22 ) which cooperates with the attachment, wherein the centering mandrel ( 22 ) is fixedly engaged with the coupling disk ( 19 ), a slide piece ( 24 ) which can be displaced in a translatory manner relative to the drive hub ( 17 ) is coupled fixedly in terms of rotation to the drive hub ( 17 ), and wherein the slide piece ( 24 ) is connected to the coupling disk ( 19 ) via universal joints ( 30, 31 ) such that the centering mandrel ( 22 ) can be displaced together with the coupling disk ( 19 ) and the slide piece ( 24 ) in a translatory manner relative to the drive hub ( 17 ).

First claim

The invention claimed is:

1 . A harvesting vehicle comprising
a mounting frame ( 10 ), wherein the mounting fame ( 10 ) is designed to couple an attachment to the mounting frame ( 10 ) and via the mounting frame ( 10 ) to the harvesting vehicle, a drive coupler ( 16 ) which engages with the mounting frame ( 10 ) and which is designed to form a drive connection between the attachment and the harvesting vehicle in order to transmit a drive power provided by the harvesting vehicle in the direction of the attachment, wherein the drive coupler ( 16 ) has a drive hub ( 17 ) which can be coupled to the harvesting vehicle, a coupling disk ( 19 ) which can be coupled to the attachment and a centering mandrel ( 22 ) which cooperates with the attachment, wherein the centering mandrel ( 22 ) is fixedly engaged with the coupling disk ( 19 ), a slide piece ( 24 ) which can be displaced in a translatory manner relative to the drive hub ( 17 ) is coupled fixedly in terms of rotation to the drive hub ( 17 ), the slide piece ( 24 ) is connected to the coupling disk ( 19 ) via universal joints ( 30 , 31 ), such that the centering mandrel ( 22 ) can be displaced together with the coupling disk ( 19 ) and the slide piece ( 24 ) in a translatory manner relative to the drive hub ( 17 ).

2 . The harvesting vehicle as claimed in claim 1 , wherein a central piece ( 29 ) is coupled between the slide piece ( 24 ) and the coupling disk ( 19 ), such that a first universal joint ( 30 ) is formed between the slide piece ( 24 ) and the central piece ( 29 ) and a second universal joint ( 31 ) is formed between the central piece ( 29 ) and the coupling disk ( 19 ).

3 . The harvesting vehicle as claimed in claim 2 , wherein a radially outwardly oriented projection ( 40 ) engages with or is configured on the central piece ( 29 ), wherein a first spring element ( 38 ) is supported on the drive hub ( 17 ) and the projection ( 40 ) and a second spring element ( 39 ) is supported on the projection ( 40 ) and the coupling disk ( 19 ).

4 . The harvesting vehicle as claimed in claim 3 , wherein
the first spring element ( 38 ) covers the first universal joint ( 30 ) on the outside at least in some portions, the second spring element ( 39 ) covers the second universal joint ( 31 ) on the outside at least in some portions.

5 . The harvesting vehicle as claimed in claim 3 , wherein the first spring element ( 38 ) and the second spring element ( 39 ) have a variable spring constant.

6 . The harvesting vehicle as claimed in claim 1 , wherein the drive hub ( 17 ) has a recess ( 25 ) with an internal toothing ( 26 ) in which a portion ( 28 ) of the slide piece ( 24 ) having an external toothing ( 27 ) engages, forming the coupling which is fixed in terms of rotation with the drive hub ( 17 ) and the translatory displaceability relative to the drive hub ( 17 ).

7 . The harvesting vehicle as claimed in claim 1 , wherein the drive coupler ( 16 ) has at least one spring element ( 38 , 39 ) which is arranged between the coupling disk ( 19 ) and the drive hub ( 17 ) and covers the universal joints ( 30 , 31 ) on the outside at least partially in some portions.

8 . The harvesting vehicle as claimed in claim 1 , wherein the mounting frame ( 10 ) is configured as a pendulum frame.

9 . The harvesting vehicle as claimed in claim 1 , characterized by a feeder unit with a feeder housing ( 11 ), wherein the mounting frame ( 10 ) is mounted on the feeder housing ( 11 ).

10 . The harvesting vehicle of claim 1 , wherein the harvesting vehicle is a forage harvester.

11 . The harvesting vehicle of claim 1 , wherein the harvesting vehicle is a combine harvester.
