Abstract
An articulated working machine vehicle, such as an articulated hauler, including a front section and a rear section pivotally connected via a connection arrangement configured to control a pivot angle between the front and rear sections for steering of the vehicle, the connection arrangement further being configured to allow the front and rear sections to rotate in relation to each other about a longitudinal axis of the vehicle. The connection arrangement comprises a rotation damper device arranged to transfer dampened relative rotation between the front section and the rear section of the vehicle.

An articulated working machine vehicle, such as an articulated hauler, comprising a front section and a rear section pivotally connected via a connection arrangement configured to control a pivot angle between the front and rear sections for steering of the vehicle, the connection arrangement further being configured to allow the front and rear sections to rotate in relation to each other about a longitudinal axis of the vehicle,
- characterized in
- that the connection arrangement comprises a rotation damper device arranged to transfer dampened relative rotation about the longitudinal axis between the front section and the rear section of the vehicle, wherein the rotation damper device comprises a first part fixed to the vehicle front section and a second part fixed to the vehicle rear section so that the first part rotates in relation to the second part when the front and rear vehicle sections rotate in relation to each other about the longitudinal axis of the vehicle,
- and wherein the rotation damper device further comprises a viscous liquid arranged between and in connection with the first and a second part so as to provide for a dampened transfer of rotation between the first and second parts.
