A spring-damper system includes at least a differential cylinder (4), a hydraulic accumulator (26) and a control valve device (1, 2). By at least one motor-pump unit (22), pressure fluid can be supplied to the annular end (6) or both the annular end (6) and the piston end (8) of the differential cylinder (4) in a closed circuit using the control valve device (1, 2).

A connecting arrangement for a stabilizer of a vehicle, with at least one lever that extends transversely to a longitudinal direction. The lever has a bearing eye provided with a non-circular inner circumferential contour. A torsion-bar spring with a rotation axis extends in the longitudinal direction. The torsion-bar spring has an outer circumferential contour, at least at one end, that matches the inner circumferential contour of the bearing eye and which fits into the bearing eye. The wall of the bearing eye is cut through by at least one slit extending in the longitudinal direction, by which two opposite wall sections of the wall are separated from one another. The two wall sections are pressed against the non-circular outer circumferential contour of the torsion-bar spring by at least one releasable clamping element.

A control unit for a vehicle that has a chassis and a driver's cab on the chassis, comprising a first data interface for receiving image data generated by an imaging sensor, a second data interface for receiving vehicle state data generated by a vehicle state sensor, an evaluation unit for evaluating the image data and/or the vehicle state data in order to generate a first control signal on the basis of the evaluation of the image data, which is configured to counteract a relative movement between the chassis and the driver's cab and/or generate a second control signal on the basis of the evaluation of the vehicle state data, which is configured to correct a setting of the imaging sensor, and a signal output unit for outputting the first and/or second control signals.

A spring-damper system consisting of at Least a differential cylinder (4), a hydraulic accumulator (26) and a control valve device (1, 2), is characterized in that by means of at least one motor-pump unit (22) pressure fluid can be supplied to the annular end (6) or both the annular end (6) and the piston end (8) of the differential cylinder (4) in a dosed circuit using the control valve device (1, 2).

Vehicle cab suspension control systems are disclosed herein. In some embodiments, the cab suspension control systems can include front cab-to-frame mounts that include controllable elastomer-based isolators that can provide real time variable damping to improve ride quality and/or road holding and reduce cab roll in response to, for example, input from one or more cab and/or frame mounted accelerometers, position sensors, etc. Embodiments of the control systems described herein can utilize a single vehicle controller (e.g., an ECU) to control all of the cab suspension components (e.g., semi-active damping technologies, air spring technologies, etc.) employed on a vehicle to provide a single suspension control solution that can provide improved ride performance, road holding, etc.

A cabin (12) of a mobile work machine (10) is adaptable to a frame of the work machine by means of an arrangement (1) which comprises longitudinal levelling means (2) for levelling the cabin in the direction of longitudinal tilting (A) of the work machine, and transverse levelling means (20) for levelling the cabin in the direction of sideward tilting (H),transverse in relation to the longitudinal direction (B) of the work machine, with respect to transverse pivoting axle (J). The transverse pivoting axle extends in a substantially orthogonal horizontal direction in relation to the longitudinal pivoting axle (C), and is adapted at a lower height than the longitudinal pivoting axle.

In one embodiment, a suspension system for a vehicle cab, the suspension system comprising: a structural assembly; a cab mounted to the structural assembly; and plural suspension units arranged between the cab and the structural assembly, the plural suspension units comprising, fore and aft, a first pair of suspension units and a second pair of suspension units, wherein a lateral distance between the second pair of suspension units is greater than a lateral distance between the first pair of suspension units.

A suspension system (2) comprising two flanges (10A, 10B), defining respective absolute reference positions, the second flange (10B) defining a relative reference position relative to the first flange (10A); and a core member (17), which is mobile only along a two degrees of freedom (M19, R19), a damper (21) applying an elastic return for bringing back the core member (17) to two degree reference positions; wherein the positions of the flanges (10A, 10B) and of the core member (17) are mechanically linked so that: when the flanges (10A, 10B) are in the absolute reference positions, the core member (17) is in the two degree reference positions; when the second flange (10B) is away from the relative reference position, the core member is away from the first degree reference position; and when the flanges (10A, 10B) are away from the absolute reference positions, the core member is away from the second degree reference position.
