Abstract: A hydraulic system for damping the motion of rotation of a swivel joint between two vehicle parts of an articulated vehicle, of an articulated bus for example, comprising a hydraulic damping device as well as an electrically triggerable proportional pressure control valve, whereas the proportional pressure control valve is arranged between the force side and the suction side of the damping device, a mechanical pressure control valve (103) being provided in addition to the proportional pressure control valve (104) in the conduit between the suction side and the force side of the damping device, and whereas a multiple-way valve is provided for the alternative drive of the pressure control valve (103) or of the proportional pressure control valve (104).

Abstract: The invention relates to an emergency exit window of a vehicle with a window pane (1) and a window frame profile (10), whereas the window frame profile (10) is retained by the window bay in the wall (20) of the vehicle, whereas the window frame profile (10) is provided with a recess (14) for the location of the window pane (1), the window frame profile (10) being provided with an opening (17) that is located at some distance of the front side of the window pane (1) and that is intended to detachably receive a first expansion member (30), a second expansion member (60) being arranged opposite the first expansion member (30) in the window frame profile (10), whereas the window bay of the vehicle is provided with a hook-shaped bracing (120) of the window frame profile, whereas the hook-shaped end of the bracing (120) is engaged in the window frame profile (10) and whereas the hook-shaped end of the bracing (120) is inserted in the window frame profile (10) at some distance of the second expansion member (60) in

Abstract: Hinge connection between two vehicles, which are connected to each other in an articulated manner such that the two vehicles can be adjusted in relation to one another around a vertical axis, a transverse axis, and a longitudinal axis. Movements around the vertical axis are made possible within the hinge by one hinge part each being associated with one of the two vehicles and by both hinge parts being adjustable in relation to one another around the vertical axis. Movements around the transverse axis and around the longitudinal axis are made possible by one of the hinge parts being connected to one of the two vehicles adjustably around the transverse axis and the longitudinal axis. The hinge part that is connected to one of the two vehicles adjustably around the transverse axis and around the longitudinal axis is held rigidly at a rigid strap, which in turn is held at the corresponding vehicle (3) via an elastic element (4).

Abstract: A bellows for articulated vehicles has side walls reinforced to have greater rigidity that the top and bottom of the bellows in order to enable relative horizontal motion while preventing bulging or collapsing of the side walls. The side walls may have one or more added layers to impart greater rigidity or may include materials inherently more rigid than those used in the top and bottom of the bellows.
