Abstract:
A frequency tuned damper assembly for dampening vibrations of a vibrating structure comprises a mass element (20) being elastically supported at opposite ends in a console via two elastic damper elements (30). At least a first damper element forms part of a first snap-lock mechanism and is in a biased state by being elastically compressed in a longitudinal direction of the mass element (20) for maintaining the snap-lock mechanism in a locked state in which the mass element (20) is held in a locked mounted position, wherein the snap-lock mechanism for assembling the damper assembly is arranged to allow, by an elastic compression in the longitudinal direction of the first damper element, the mass element to be brought into its locked mounted position by a transverse movement in relation to the longitudinal direction. A method for assembling a frequency tuned damper assembly is also disclosed.
Abstract:
In a vehicle having a wheel or endless track driven undercarriage supporting a lifting arm, the undercarriage (10) of the vehicle is provided with formations (20) on a vertical lateral surface (18) to engage with mating formations (22) on a vertical lateral surface of a removable counterweight (16). The formations (20,22) are shaped to engage by sliding the counterweight (16) in a vertical plane relative to the undercarriage (10) and, when engaged, they support the weight of the counterweight (16) vertically and prevent separation of the counterweight (16) from the undercarriage (10).
Abstract:
System for balancing the loads on the wheels of an industrial vehicle, the industrial vehicle comprising at least a front axle (ant) and a rear axle (post), a loading platform and a transported load and/or ballast (Z) slidably associated with the loading platform of the vehicle, with a reciprocal position that can be controlled by at least an actuator; the system comprising means for calculating a load transfer (DR) between the wheels of the vehicle with respect to an initial condition of load distribution and means for balancing such load transfer (DR) with a shift (x) of the load or ballast (Z) restoring said initial condition.
Abstract:
Atténuateur de vibrations pour véhicule automobile, du type comprenant un batteur (2), dont la masse (3) et l'agencement au sein du compartiment moteur dépendent de la gamme de fréquence des vibrations à atténuer, caractérisé en ce que le batteur (2) comporte une masse (3) qui coopère avec un socle par des moyens de solidarisation aptes à libérer la masse (3) au-delà d'un seuil prédéterminé de décélération du véhicule.
Abstract:
Bei einer Vorrichtung zur Tilgung von aufbauseitigen Torsionsschwingungen an einem Cabriolet-Fahrzeug wird ein elastisch gehaltener Massekörper verwendet. Der Tilger (2) ist an einem Rahmen (3) einer Windschutzscheibe (4) über Schublager (21) elastisch gehalten und mit Abstand zum Rahmen in Querrichtungen (7,8) des Fahrzeugs relativ frei schwingend angeordnet. Der Tilger weist eine die Torsionseigenfrequenz des Fahrzeugs im Bereich des Rahmens gleiche Frequenz auf, wobei die Lager eine durch ihre Geometrie bedingte Schubsteifigkeit besitzen. Der Tilger ist über mindestens ein mittiges Schublager zum Rahmenelement hin elastisch abgestützt, wobei endseitig der Tilgermasse jeweils ein Blattfederelement (24) angeordnet und, eine Querbewegung der Tilgermasse zulassend, abstützend zum Rahmenelement gelagert ist.
