Regeleinrichtung, welche den Fluidfluß in die/aus den Kammern (18, 20) steuert bzw. regelt.
Abstract:
A machine (100) employing controllable mounts (106) and a method for controlling such mounts (106) based on operator input are disclosed. The controllable mount (106) may include a housing (108), a pin (120), rheological fluid (116) within the housing (108) and coils (131) provided proximate to the rheological fluid (116). As current is applied to the coils (131), the apparent viscosity of the rheological fluid (116) is increased, and in so doing so is the stiffness and damping of the controllable mount (106). Depending on various factors, the operator may want a particular level of feedback. For example, when fine grading, the operator may want to feel every vibration and thus the controllable mounts (106) should be as stiff as possible. The present disclosure therefore provides the operator with the ability to select the desired level of feedback. This can be done through an operator interface (188) that enables an operator to specifically set the current to each mount (106), or enter other information whereupon a processor (168) of the control system (182) executes the necessary algorithm (262) to provide the operator with the optimum level of feedback.

Abstract:
A variable load limiting device for a vehicle safety belt assembly is provided for controllably restraining a vehicle occupant by the vehicle safety belt assembly during deceleration of a vehicle. The device includes a body including a fluid chamber for containing a free-flowing fluid therein. A wiper assembly is operably disposed in the fluid chamber and selectively coupled to the vehicle safety belt assembly. The wiper assembly creates a pressure differential within the fluid chamber when a force in excess of a predetermined value is applied to the vehicle safety belt assembly. A throttle valve is operably connected to the body for controlling fluid pressure in the fluid chamber.
Abstract:
Some embodiments relate to a compact noncontact mechanical coupling, damping, and/or load bearing device comprising an internal load bearing member and an external load bearing member mated in an interdigitated relation while maintaining a gap therebetween. Some embodiments include a means for maintaining the gap between the internal and external load bearing members including, without limitation, hydrostatic means, hydrodynamic means, electrorheological fluids, magnetorheological fluids, electric fields, and/or magnetic fields.
Abstract:
A stabilizer bar (D, E, F) for controlling the roll of an automotive vehicle has left and right sections (16, 18), each provided with a torsion rod (22, 70) and a torque arm (24). The torsion rods are aligned along a transverse axis (X) and attached to a structural component (B) of the vehicle, while the torque arms are connected to the left and right control arms (2) of the vehicle's suspension system (A). In addition, the bar has a coupling (20, 72, 80) between the torsion rods of the two sections for controlling the torsional stiffness of the bar. The coupling includes a rotor (343, 86) fitted to one of the torsion rods and a housing (36, 88) fitted to the other torsion rod, with the housing receiving the rotor, such that a cavities exist between the rotor and housing. Both the rotor and housing carry vanes (44, 56, 82, 104), that alternate so that the vanes of the rotor are located between the vanes of the housing. The cavities contain a magneto-rheological fluid (40, 82). The bar also includes an electrical coil (38, 138) controls the viscosity of the fluid either at the coupling or at a valve (84) located remote from the coupling, but in either place, such that the variations in the viscosity of the fluid control the torsional stiffness of the stabilizer bar.
Abstract:
The invention relates to a valve (1) on the basis of electrorheological and/or magnetorheological fluids, comprising a fluid inlet channel (3) which is connected with a fluid outlet channel (4) via a valve gap (5) filled with an electrorheological and/or magnetorheological fluid. The surfaces delimiting the valve gaps are configured as capacitor fields and/or coil systems which can be electrically controlled and impingement of said fields acts on the fluid circulating through the valve gap. The aim of the invention is to improve such a valve in such a way that it can be used in a variety of applications and permits high pressures and flow rates. To this end the invention provides for least one of the surfaces delimiting the valve gap to be movable.
Abstract:
A device for prevention of pitching rolling of a vessel for the purpose of absorbing the rolling motion of the vessel and of providing the passengers with comfortable voyage. The device comprises a lead container (20) containing lead (30) therein and having an opening (21) at its top, a heating coil (40) arranged on a bottom surface of the lead container (20) to heat and melt the lead (30) in the container (20) and covered with a heat insulating cover (50), a support frame (60) connecting the lead container (20) to a bottom plate (70) of the vessel, a support column (13) connected to a bottom surface (11) of a cabin and inserted in the lead container (20) through the opening (21) of the container (20) and having a plate floater (14) at its lower end, the plate floater (14) contacting with the surface of the lead (30) of the container (20), and a lid (22) covering the container (20) to hermetically seal the opening (21) and tightly engaging with the support column (13), the lid (22) being slidable with respect to an outer surface of the container (20). This device is installed under the bottom of a cabin of the vessel and prevents the pitching rolling of the vessel body from being transferred to the cabin, thereby providing the passengers in the cabin with a safety and comfortable voyage irrespective of the pitching rolling.
