Abstract

This articulation device for an articulated vehicle comprises a first shackle ( 14 ), a second shackle ( 16 ), and an articulation joint ( 18 ) comprising a first articulation member ( 20 ) comprising a single first section ( 52 ) and a second articulation member ( 22 ) comprising a single second section ( 60 ). The first section ( 52 ) and the second section ( 60 ) are rotatable relative to each other; the first shackle ( 14 ) is connected to the first articulation member ( 20 ) and the second shackle ( 16 ) is connected to the second articulation member ( 22 ). The second articulation member ( 22 ) comprises a single connecting member ( 66 ) through which the second section ( 60 ) is connected to the second shackle ( 16 ), the connecting member ( 66 ) being adapted to adjust the position of the second section ( 60 ) relative to the second shackle ( 16 ) along a longitudinal axis (X 2 -X 2 ) and along a transverse axis (Y 2 -Y 2 ).

First claim

What is claimed is:

1. An articulation device for an articulated vehicle comprising:
a first shackle adapted to be attached to a first car of the articulated vehicle,
a second shackle adapted to be attached to a second car of the articulated vehicle, and
an articulation joint comprising a first articulation member comprising a single first section, the articulation joint comprising a second articulation member comprising a single second section,
the first section defining a first longitudinal axis, the second section defining a second longitudinal axis, the first section and the second section being rotatable relative to each other about a first transverse axis extending transversely to the first longitudinal axis and the second longitudinal axis the first shackle being connected to the first articulation member and the second shackle being connected to the second articulation member;
wherein the second articulation member comprises a single connecting member through which the second section is connected to the second shackle, the connecting member being adapted to adjust the position of the second section relative to the second shackle along the second longitudinal axis and along a second transverse axis extending perpendicularly to the second longitudinal axis and the first transverse axis.

2. The articulating device for an articulated vehicle according to claim 1 , wherein the connecting member adjustably defines the position of the second section relative to the second shackle along the second longitudinal axis independent of the adjustment of the second section relative to the second shackle along the second transverse axis.

3. The articulation device for an articulated vehicle according to claim 1 , wherein the first articulation member comprises:
a first adjustable stop movable relative to the first section along the first longitudinal axis, and
a first clamping member,
the first adjustable stop and the first clamping member being adapted to set the first section relative to the first shackle.

4. The articulation device for an articulated vehicle according to claim 1 , wherein the second articulation member comprises:
a second adjustable stop movable relative to the second section along the second longitudinal axis, and
a second clamping member,
the second adjustable stop and the second clamping member being adapted to fasten the connecting member relative to the second section.

5. The articulation device for an articulated vehicle according to claim 1 , wherein the connecting member is rotatable relative to the second section about the second longitudinal axis, wherein the second shackle defines a third longitudinal axis parallel to the second longitudinal axis and offset from the second longitudinal axis, the connecting member being rotatable relative to the second shackle along the third longitudinal axis, and wherein the device includes at least one fastening member adapted to fasten the connecting member relative to the second shackle.

6. The articulation device for an articulated vehicle according to claim 5 , wherein the first section is movable relative to the second section along the vertical axis over a range of between −20 mm and +20 mm.

7. The articulation device for an articulated vehicle according to claim 1 , wherein the connecting member is movable in translation along the second transverse axis relative to the second shackle, and wherein the articulation device comprises at least one fastening member adapted to fasten the connecting member relative to the second shackle.

8. An articulated vehicle comprising:
a first car, and
a second car,
wherein the vehicle comprises an articulation device for an articulated vehicle according to claim 1 , the first shackle being attached to the first car and the second shackle being attached to the second car.

9. A method of adjusting an articulation device for an articulated vehicle, the articulation device comprising:
a first shackle adapted to be attached to a first car of the articulated vehicle,
a second shackle adapted to be attached to a second car of the articulated vehicle, and
an articulation joint comprising a first articulation member comprising a single first section, the articulation joint comprising a second articulation member comprising a single second section,
the first section defining a first longitudinal axis, the second section defining a second longitudinal axis, the first section and the second section being rotatable relative to each other about a first transverse axis extending transversely to the first longitudinal axis and the second longitudinal axis the first shackle being connected to the first articulation member and the second shackle being connected to the second articulation member;
wherein the second articulation member comprises a single connecting member through which the second section is connected to the second shackle, the connecting member being adapted to adjust the position of the second section relative to the second shackle along the second longitudinal axis and along a second transverse axis extending perpendicularly to the second longitudinal axis and the first transverse axis,
wherein the second articulation member comprises:
a second adjustable stop movable relative to the second section along the second longitudinal axis, and
a second clamping member,
the second adjustable stop and the second clamping member being adapted to fasten the connecting member relative to the second section,
the method comprising:
adjusting the position of the connecting member by translating the connecting member relative to the second section along the second longitudinal axis; and
fastening the connecting member to the second section by the second adjustable stop and the second clamping member.

10. A method of adjusting an articulation device for an articulated vehicle, the articulation device comprising:
a first shackle adapted to be attached to a first car of the articulated vehicle,
a second shackle adapted to be attached to a second car of the articulated vehicle, and
an articulation joint comprising a first articulation member comprising a single first section, the articulation joint comprising a second articulation member comprising a single second section,
the first section defining a first longitudinal axis, the second section defining a second longitudinal axis, the first section and the second section being rotatable relative to each other about a first transverse axis extending transversely to the first longitudinal axis and the second longitudinal axis the first shackle being connected to the first articulation member and the second shackle being connected to the second articulation member;
wherein the second articulation member comprises a single connecting member through which the second section is connected to the second shackle, the connecting member being adapted to adjust the position of the second section relative to the second shackle along the second longitudinal axis and along a second transverse axis extending perpendicularly to the second longitudinal axis and the first transverse axis,
wherein the connecting member is rotatable relative to the second section about the second longitudinal axis, wherein the second shackle defines a third longitudinal axis parallel to the second longitudinal axis and offset from the second longitudinal axis, the connecting member being rotatable relative to the second shackle along the third longitudinal axis, and wherein the device includes at least one fastening member adapted to fasten the connecting member relative to the second shackle,
