Abstract:
1. A joint for an articulated vehicle having vehicle parts with the joint between the vehicle parts, the joint comprising: two joint segments that are rotatable relative to each other; and a damping device comprising two piston cylinder dampers, one piston cylinder damper being disposed on each side of the center longitudinal axis of the joint and extending between the two joint segments; each piston cylinder damper having a piston rod and a piston received in a cylinder, the cylinder having a bottom, the piston having a cylinder bottom side and an opposite piston rod side; and the piston of each piston cylinder damper having at least one check valve with a flow direction from the cylinder bottom side to the piston rod side so as to reduce the effective damping torque when the piston moves towards the cylinder bottom such that in any angular position of the joint segments, the total damping torque of the two piston cylinder dampers acting on the joint is substantially equal in a positive as well as in a negative direction of rotation.
