Abstract

An articulated joint ( 1 ) for an implement carrier vehicle ( 10 ), said articulated joint ( 1 ) being adapted to connect a front vehicle body ( 2 ) and a rear vehicle body ( 3 ). The articulated joint ( 1 ) comprises a socket ( 4 ) arranged in a first articulation link portion ( 5 ), said first articulation link portion being adapted to be connected to one of said front or said rear vehicle body ( 2, 3 ). The articulation joint ( 1 ) further comprises a stud ( 6 ) arranged in a second articulation link portion ( 7 ), and extending along an axis A, said second articulation portion ( 7 ) being adapted to be connected to another one of said front or rear vehicle body ( 2, 3 ), said stud being pivotally arranged in said socket ( 4 ), and at least one annular sealing device ( 8 ) at least partly enclosing said stud and socket, and wherein said annular sealing device ( 8 ) comprises a sealing flange ( 9 ).

First claim

1 - 15 . (canceled)

16 . An articulated joint for an implement carrier vehicle comprising a front vehicle body and a rear vehicle body, the articulated joint comprising:
a socket located in a first articulation link portion, the first articulation link portion configured to be connected to one of the front vehicle body or the rear vehicle body; a stud located in a second articulation link portion and extending along an axis, the second articulation portion configured to be connected to the other of the front vehicle body or the rear vehicle body, the stud configured to be pivotally received in the socket; an upper annular sealing device comprising a first sealing flange configured to at least partly enclose the stud and the socket; and a lower annular sealing device comprising a second sealing flange configured to at least partly enclose the stud and the socket.

17 . The articulated joint according to claim 16 , wherein the upper annular sealing device, the lower annular sealing device, the first sealing flange, and the second sealing flange are configured to provide an annular sealing space, the annular sealing space configured to hold lubricant.

18 . The articulated joint according to claim 17 , wherein the annular sealing space encloses the stud and the socket.

19 . The articulated joint according to claim 16 , wherein the first and second sealing flanges are each directed away from the axis.

20 . The articulated joint according to claim 16 , wherein the upper annular sealing device and the lower annular sealing device each comprise a substantially V-shaped cross-section.

21 . The articulated joint according to claim 16 , further comprising a cover plate configured to at least partly cover the stud and the socket.

22 . The articulated joint according to claim 21 , wherein one of the upper annular sealing device or the lower annular sealing device is attached to the cover plate.

23 . The articulated joint according to claim 21 , wherein one of the first sealing flange or the second sealing flange seals the cover plate to the first articulation link portion.

24 . The articulated joint according to claim 21 , wherein one of the first sealing flange or the second sealing flange seals the cover plate to the second articulation link portion.

25 . The articulated joint according to claim 21 , wherein a spherical bearing is configured to be inserted into the socket, and wherein the stud is configured to be received in the spherical bearing.

26 . The articulated joint according to claim 25 , wherein one of the first sealing flange or the second sealing flanges seals the cover plate to the spherical bearing.

27 . The articulated joint according to claim 16 , wherein each of the upper annular sealing device and the lower annular sealing device is attached to either the first articulation portion or the second articulation portion.

28 . An implement carrier vehicle, comprising:
a front vehicle body and a rear vehicle body; and an articulated joint configured to connect the front vehicle body and the rear vehicle body, the articulated joint comprising:
a socket located in a first articulation link portion, the first articulation link portion configured to be connected to one of the front vehicle body and the rear vehicle body;
a stud located in a second articulation link portion and extending along an axis, the second articulation portion configured to be connected to the other of the front vehicle body and the rear vehicle body, the stud configured to be pivotally received in the socket;
an upper annular sealing device comprising a first sealing flange configured to at least partly enclose the stud and the socket; and
a lower annular sealing device comprising a second sealing flange configured to at least partly enclose the stud and the socket.

29 . The implement carrier vehicle according to claim 28 , wherein the implement carrier vehicle comprises two or more of the articulated joint.

30 . The implement carrier vehicle according to claim 28 , wherein the upper annular sealing device, the lower annular sealing device, the first sealing flange, and the second sealing flange are configured to provide an annular sealing space, the annular sealing space configured to hold lubricant.

31 . The implement carrier vehicle according to claim 30 , wherein the annular sealing space encloses the stud and the socket.

32 . The implement carrier vehicle according to claim 28 , wherein the first and second sealing flanges are each directed away from the axis.

33 . The implement carrier vehicle according to claim 28 , wherein the upper annular sealing device and the lower annular sealing device each comprise a substantially V-shaped cross-section.

34 . The implement carrier vehicle according to claim 28 , further comprising a cover plate configured to at least partly cover the stud and the socket.

35 . The implement carrier vehicle according to claim 34 , wherein one of the upper annular sealing device or the lower annular sealing device is attached to the cover plate.
