  • Patent number: 9951840
    Abstract: A method and an assembly for absorbing energy during an overload event. An energy absorber reduces loads on an object being transported on a loading unit during a single overload event, which introduces such a high degree of energy that there is an overwhelming likelihood the object would be damaged without an energy absorber. Measurement values on the current state of the loading unit are sensed. A control device determines an overload event and a damping of the energy absorber is set to a high value after the detection of the overload event. The damping is maintained for a specified prolonged time period and controlled dependent on the measurement values during the overload event to increase the load for objects during the specified time period initially to a specified threshold load and after the specified time dependent on the measurement values detected during the overload event.

  • Patent number: 9841078
    Abstract: An energy absorber is controlled in an overload event to absorb potentially damaging energy. The energy absorber acts between a receiving unit for receiving objects for transporting and a carrier device that connects to a transporter. An absorber force can be influenced by an electrically controlled magnetic field unit. Measurement values of loads acting on the loading unit are captured sequentially and an overload event is determined if a measure derived from the measurement values exceeds a predetermined threshold value. After the onset of an overload event a prognosticated load curve of the loading unit is assessed from a multitude of measurement values captured from the onset of the overload event. A planned power flow curve for the magnetic field unit is determined and the load curve is damped time-dependent so that a planned load curve ensues which remains beneath a predetermined load limit.

  • Patent number: 9835221
    Abstract: An energy absorber reduces an excessive load between an object and an assembly in an overload event. The energy absorber includes an absorber cylinder and a piston device with an absorber piston and a piston rod. A first chamber of an absorber chamber is filled with a field-sensitive absorber fluid. The piston has an absorber valve with an absorber duct extending in an axial direction and being subject to a selective field of a field generating device. A ratio of the outer diameter of the piston rod to an outer diameter of the absorber piston is greater than 0.6 and the first chamber extends in a space around the piston rod. During the relative motion of the fastener and the holding device the field-sensitive absorber fluid is urged through the damping duct of the absorber piston.

  • Patent number: 7744155
    Abstract: The protection system is used especially for the protection against a fatal effect of vertical accelerations triggered by a landmine on the passengers of an armored vehicle. For this, the sitting unit consisting of a seat body (7) and a backrest (8) is held movable in vertical direction and is coupled with an end area (15) of a longitudinally variable damping device (11), whose other end (13) is connected to the roof (4) of the vehicle (2) through a carrying equipment (6). In addition, the sitting unit is carried with vertical distance from the vertical guide (18) in a lower guide path (19) transversally directed so that the sitting unit executes both a downward as well as a tilting movement relative to the vehicle together with a passenger (3) during loading through vertical acceleration. In this way, an improved usage of the constructively limited effective length of the damping device (11) occurs so that the effect of the protection system is essentially improved.

  • Patent number: 7712823
    Abstract: The armored vehicle (1), showing a bottom and a top shell (4, 5) has a reinforced floor structure for protection against mines, in that the floor area (6) of the subshell (4) is connected rigidly with an inner floor plate (7) via bracing elements (13, 14, 15) having longitudinal and transverse walls, which are also connected with the side walls (11, 12) of the subshell (4) along their borders (9, 10). The minimum height of the stiff bracing elements (13, 14, 15) corresponds to distance provided for the arrangement of a drive shaft between the inner floor plate (7) and the floor area (6).
