Abstract
Method and arrangement including a vehicle having a first and a second vehicle section connected to an articulation that allows rotation about a vehicle longitudinal axis of the vehicle. A positioning arrangement is included that has at least one adjusting device in which the positioning arrangement includes operation by at least one adjusting device in order to rotate the first and second vehicle sections into a predefined basic position in relation to one another.
Claims14
An articulated vehicle comprising:
- a first and a second frame half connected to an articulation that allows the first and the second frame halves to rotate in relation to one another about a longitudinal axis of the vehicle;
- a positioning arrangement comprising at least one adjusting device;
- and
- said positioning arrangement further comprising at least one means of operation operated by said at least one adjusting device in order to rotate the first and second frame halves about the longitudinal axis of the vehicle into a predefined basic position in relation to one another and wherein the positioning arrangement has operative and inoperative conditions in which the frame halves are fixed in the predefined basic position in relation to one another when the positioning arrangement is in the operative condition and in which the frame halves are freely rotatable in relation to one another when the positioning arrangement is in the inoperative condition and said inoperative condition is triggered when a predetermined angular difference between frame halves is determined;
- wherein the means that operate the positioning arrangement comprise two guide arms operated by the at least one adjusting device.
A method in an articulated vehicle having an articulation which allows a first and a second frame half to rotate in relation to one another about the vehicle longitudinal axis for rotating the first and the second frame halves into a predefined basic position in relation to one another, said method comprising:
- rotating at least one of the frame halves about the longitudinal axis of the vehicle into the predefined basic position by means of at least one adjusting device;
- and providing two guide arms positioned on the first frame half and which are brought against two bearing surfaces positioned on the second frame half by means of at least one adjusting device.
