  • a vibration damper for the torsional vibrations introduced into a steering wheel via a steering spindle.
  • the amplitudes of oscillations in the plane perpendicular to the longitudinal axis of the steering column are essentially rectilinearly oscillating oscillatory movements, that is, of oscillations which occur in the Steering column longitudinal axis vertical plane occur, for example, in the horizontal direction or in the vertical direction.
  • a hydraulic damper damper tuned to the natural frequency of the steering system for reducing such steering wheel torsional vibrations, in which a damper mass supported on springs oscillates with large deflections in a hydraulic damping medium. It can be provided as a damper damper attached to a tie rod stroke damper with oscillating in the axial direction, designed as a damper piston damper. Alternatively, a rotary absorber damper fastened to the steering column and having a damper mass that swings in the circumferential direction is proposed in this document. In practice, however, torsional vibration dampers have not yet become established in motor vehicle steering systems.
  • a larger mass is preferably attached to the steering wheel in the region of the largest possible diameter in such an elastic manner that this mass can vibrate at least slightly compared to the steering wheel.
  • This mass should be able to execute torsional vibrations essentially around the center of the steering wheel or around the center of the steering wheel. It is important that this mass is not negligibly small compared to the weight of the steering wheel, which is why the specific weight of this so-called mass, which is best formed by at least one suitably shaped metal element, is significantly greater than that of the steering wheel base material or essentially that Steering wheel forming material mix should be.
  • this mass can be arranged as far as possible, or at least one metal element forming this mass, if this metal element or the possibly a plurality of metal elements is / are essentially accommodated in the steering wheel rim, in such a way that it or they can be or are at least slightly movable relative to it.
  • the metal element is then preferably ring-shaped, in the sense of an advantageous production a single closed metal ring can be elastically embedded in the steering wheel rim.
  • an inner metal ring can be guided so as to be displaceable relative to an outer metal ring surrounding it, around its common steering wheel center.
  • the elastic connection of the metal element to the steering wheel or steering wheel rim can take place via an elastomer element, this so-called connection being designed in such a way that slight torsional vibrations preferably around the center of the steering wheel between the steering wheel and the (or) metal element (s) ) possible are.
  • the metal element can be completely connected to the steering wheel rim via an elastic connection, but next to it - viewed over the cross section of the steering wheel rim - only a partial, i.e. possible in some areas and in particular over one or more segment (s) elastic connection.
  • the torsional vibrations introduced into the steering wheel by the oscillatory system formed by the motor vehicle steering and the vehicle axle with the steerable wheels can be reduced, in the best case to the extent that they are no longer perceived as disturbing by the driver of the motor vehicle - be taken.
  • the Steering wheel rim or the crown skeleton forming the steering wheel rim which, as usual, is still foamed or wrapped, has a recess that receives the metal element. This recess can be almost completely filled with a suitable elastomer material, in which then or via which the metal element is then virtually floating.
  • the recess can also be provided with a cover on which the metal element is suspended elastically.
  • the elastic suspension mentioned does not have to take place via a suitably designed elastomer element; rather, other elastic suspensions, for example via spring elements or the like, are also possible.
  • the metal element can be made of brass or steel, while the lighter steering wheel rim and the steering wheel spokes can be formed by a light metal skeleton, in particular made of aluminum or magnesium.

  • the steering wheel rim 1 is encased by a handle structure, not shown, which is foamed, for example.
  • a circumferential recess 2 on the rear side of the steering wheel facing away from the driver, into which a metal ring 3 (here closed and thus extending over the entire rim circumference) is inserted, which - to choose a more general term - is also referred to as the metal element 3 according to the invention.
  • This metal element 3 is held elastically on the steering wheel rim 1 or in its recess 2 such that the metal element 3 or the metal ring 3 can perform at least a slight oscillating movement about the axis of rotation 7 relative to the steering wheel rim 1.
  • the recess 2 is almost completely filled with a suitable elastomer material, which forms an elastomer element 4, in or over which the metal element 3 is mounted in a quasi-floating manner.

Abstract

L'invention concerne la direction d'un véhicule, comportant un amortisseur de vibrations pour les vibrations torsionnelles induites dans le volant par l'intermédiaire de la barre de direction. Le volant est doté d'au moins un élément métallique (3) situé le plus loin possible du centre du volant, cet élément ayant un poids spécifique sensiblement supérieur à celui du matériau constituant le volant. Cet élément métallique (3) est de préférence annulaire et encastré de manière élastique dans la couronne du volant (1), de sorte qu'il (3) peut au moins légèrement tourner autour du centre du volant sur le plan du volant, par rapport à la couronne du volant (1). Accroché à la couronne du volant par un élément élastomère (4), cet élément métallique, vu en section transversale, est relié à ladite couronne entièrement ou seulement partiellement au moyen d'une attache élastique. La couronne du volant (1) comporte de préférence un évidement (2) destiné à recevoir l'élément métallique, cet évidement étant pourvu d'un recouvrement (5), auquel est suspendu l'élément métallique de manière élastique.
