Abstract: The individual room units presently used in aircraft, e.g. crew rest rooms, are usually fixed installations so that quick on-demand changeover of passenger seats to such a room unit may only be feasible with an extended change-over period in the repair hangar. According to an exemplary embodiment of the present invention, a modular wall construction system for aircraft cabins is provided, which comprises individually prefabricated wall construction panels (701, 702, 703) adapted for a quick installation with connecting elements without additional tools. This may result in the formation of at least one room of a room unit (1) of individual size and geometry.

Abstract: A joint arrangement is proposed in a vehicle having a knuckle steering system where the steering linkage comprises one tie rod (2) flexibly connected with the steering cylinder via one joint (9), on lever element (3) flexibly connected with the tie rod (2) and the axle bridge (1) via one joint (7) provided between the tie rod (2) and the lever element (3) and one joint (8) provided between the elver element (3) and the axle bridge (1) and one coupler (5) flexibly connected with the axle head (6) and the tie rod (2) via one joint (10) provided between the coupler (5) and the tie rod (2), the lever element (3) and the coupler (5) being connected with the tie rod (2) via a double joint (6), at least one joint (7) being designed as radial joint and the other joints (8, 9, 10) as ball joints.

Abstract: An axle pivot steering device (4) of a vehicle having first lever elements (8A—1, 8B—1), which are respectively operatively connected, via a second lever element (8A—2, 8B—2), with a wheel carrier (10A, 10B). The first lever elements (8A—1, 8B—1) and the second lever elements (8A—2, 8B—2) are connected with third lever elements (13A, 13B), in an articulated manner, at fixed rotational points (14A, 14B). At least two of the lever elements (8A—1, 8A—2, 13A) are designed to be fork-shaped and be inter-coupled, in an area of the rotational points (14A, 14B), by a bearing bolt (15) such that the bearing torques resulting from the bearing forces acting on the bearing bolt (15) are at least approximately zero.

Abstract: A vehicle having at least one axle (1) steerable via a knuckle steering system (4) which is designed with one main steering cylinder device (6) flexibly connected with track rods (8A, 8B). The track rods are in operative connection with wheel carriers (10A, 10B). A steering kinematics of the knuckle steering system between the main steering cylinder device and one wheel carrier (10A, 10B), is in flexible operative connection with a lever element (13A, 13B) rotatable around a fixed pivot (14A, 14B) in a manner that a steering angle error corresponding to a demanded steering angle is substantially minimized by a reduction of the angle of lock of the wheel (2A or 2B) currently outside the curve in relation to an angle of lock of the wheel (2B or 2A) currently inside the curve.

At least two of the lever elements (8A—1, 8A—2), in the connecting area of the lever elements (8A—1, 8A—2, 13A) are designed fork-shaped and interspaced, the same as made by bearing points crossed by a bearing bolt (15) so that the bearing torques resulting from the bearing forces acting on the bearing bolt (15) are at least approximately zero.

Abstract: A method for a steering system adjustment and a steering system of articulated wheels of a vehicle having a knuckle steering system by which, both in a four-wheel and a two-wheel steering mode and preferably also in any desired intermediate modes, the Ackermann angle and optionally a desired steering angular deflection can be respectively adjusted, preventing the former disadvantages resulting from a rigid localization of an Ackermann intersection point. The method improves the total driving behavior of the vehicle and reduces the wear detectable on tires and chassis sites. The method for steering system adjustment and/or for steering system of the wheels provides that an Ackermann intersection point is moved by an operator or a selector and control device along a vehicle longitudinal axis and/or the extension thereof within an area determined by the maximum steering angle of the wheel axles.
