Abstract: A roll stabilizer for a motor vehicle includes a torsion bar and a vibration damper located on the torsion bar. The vibration damper is configured to vibrate relative to the torsion bar. The vibration damper includes two half-shells formed together about the torsion bar. Damper elements are disposed between the half-shells. The damper elements can be adjusted via an adjustment component to alter the rigidity of the damper elements.

Abstract: A fuel cell stack and a compression system for providing compressive force to a fuel cell stack having first and second ends is provided. The compression system includes asymmetric leaf springs operatively connected to first and second ends of the fuel cell stack. Each leaf spring includes a slot having first and second connector positions. The compression system also includes tension members connected to the leaf springs. The tension members compress the leaf springs to provide a compressive load to the fuel cell stack.

Abstract: An apparatus for locking a sheet of metal to be shaped in a press, comprising at least one fluid-operated actuator for translational motion of a first sheet presser, adapted to support, in an initial operation step a sheet of metal to be shaped, arranged above a first lower die part, coupled to the base of the press. The first presser cooperates with a second presser, coupled to the second die part associated with the upper ram of the press, in locking a perimetric portion of the sheet of metal during shaping. The actuators are part of a circuit for regenerating and supplying the working fluid, provided with devices for the delayed return of the actuators, upon opening the press, for shaped sheet protection.

Abstract: A lift strut with directional damping comprising a housing comprising a wall that defines a housing chamber, the housing defining an axis; spring means located in the chamber; piston means movable through the chamber along the axis in a first direction and a second direction, the spring means biasing the piston means in the first direction, the piston means comprising a shaft, a seat connected to the shaft along the shaft length, and a resilient member fixed to the seat, the resilient element comprising at least one primary damping ridge and a damping tongue, each of the at least one primary damping ridges being in friction engagement with the housing as the resilient member is moved in the first and second directions, the damping tongue being in engagement with the housing wall when the resilient member is moved in the first direction and being located away from the housing wall when the resilient member is moved in the second direction.

Abstract: A vehicle system component is provided with an electrical charge to resist corrosion. Preferably, the electrical charge is generated by movement of components adjacent to the suspension component. Friction surfaces may be placed in contact with each other such that and heat is generated upon movement of the vehicle system components. The heat is transferred into electrical energy. In another embodiment, an electrical coil receives a magnetic member which moves within the coil to generate the current. The charge may be stored in a capacitor and periodically dispatched onto said component. The invention thus provides a low cost and simplistic way of resisting corrosion to vehicle components, and in particular to vehicle suspension components.

Abstract: A damper device comprising a first and second assembly suitable for guided relative displacement. The first assembly is supported stationarily with respect to a reference. The second assembly is supported for guided relative displacement with respect to the first assembly and the reference. A driving connection connects the second assembly and a system to be damped. A shoe rests against the first assembly and a resilient control that works in buckling is interposed between the shoe and the second assembly. The resilient control exerts a force on the shoe tending to urge the shoe against the first assembly during an active stage of damper device loading, corresponding to relative displacement in a first direction between the first and second assemblies and to reduce the force exerted by the shoe during a passive stage of damper device loading corresponding to relative displacement in a second direction between the first and second assemblies.

Abstract: A coated coil spring wrapped in a coating member prepared from a soft synthetic resin foam, wherein the coating members of the respective coil spring turns constituting at least the effective region of the coil spring are provided with a helical clearance; and the width of said clearance accounts for 0.15 to 0.50 times the width of the adjacent coil spring turns.
