Definitions

  • the invention relates to a spatial independent wheel suspension for wheels of rail vehicles, in which the wheel unit consisting of the wheel, the wheel bearing, the non-rotating wheel carrier and optionally a drive and / or braking device with respect to the vehicle can perform steering movements and / or spring movements, and in which the wheel carriers are connected movably to the vehicle via a handlebar which has joints at its ends, and to a handlebar acting as a tie rod through or via intermediate elements with the wheel carrier of the opposite wheel.
  • the invention is therefore based on the object of avoiding the known disadvantages of bogies and rigid axles and, moreover, of creating a wheel linkage on the rail vehicle which brings the aforementioned improvements.
  • the solution to the problem is that the articulation point of at least one handlebar on the vehicle can be adjusted depending on the driving state, such as driving forwards or backwards, straight or cornering, braking or driving and / or depending on the state of wear of the wheel tires.
  • the links are advantageously arranged essentially on the side of the wheel unit facing away from the center of the vehicle the momentary steering axis determined by the arrangement of the handlebars lies at least approximately in the plane perpendicular to the axis of rotation of the non-pivoted wheel, which also contains the contact point wheel-rail (wheel contact point).
  • the advantage of the independent wheel suspension according to the invention lies primarily in the fact that no bogie is required and thus saves considerable weight in the unsprung masses, which again benefits the smooth running of the rail vehicle. Furthermore, by eliminating the rigid axle, the invention allows the floor height of the vehicle to be lowered considerably (low-floor vehicle), which makes it easier to get in and out and thus increases the comfort of the passengers. By guiding the wheel on the handlebars and the virtual swivel axis thus formed the entire installation space inside the wheel stands for the drive, for example through a wheel hub motor with a planetary gear connected downstream.
  • an example embodiment of the invention is shown schematically using a rail wheel 11 which rolls on a rail 12 and forms the wheel contact point 13 there.
  • the wheel 11 rotates on an axis 14 which is firmly connected to the non-rotating wheel carrier 15, 16.
  • Drive and / or braking devices can also be arranged on the wheel 11 in a known manner.
  • the wheel unit consisting of wheel 11, wheel bearing on axle 14 and non-rotating wheel carrier 15, 16 is articulated on vehicle 21 with four links 17.18.19 and 20 such that the articulation points on the vehicle are at a greater distance than on part 16 of wheel carrier 15, 16.
  • the handlebars 17 - 20 are essentially on the side facing away from the center of the vehicle Wheel unit 15, 16 is arranged, the momentary steering axis 22 defined by the arrangement of the links 17-20 being at least approximately in the plane 23 lying perpendicular to the axis of rotation 14 of the non-pivoted wheel 11, which also contains the point of contact wheel-rail (wheel contact point 13) .
  • a spring 24 is arranged on a handlebar 19, which is supported on the vehicle 21.
  • a tie rod 25 is articulated on the wheel carrier 15, 16, which is connected to the wheel carrier of the opposite wheel.
  • the two links 17 and 18 are articulated on the vehicle 21 in such a way that their articulation points on the vehicle side can be shifted horizontally in a guide 26, 27 and approximately parallel to the longitudinal axis of the vehicle.
  • the two guides 26 and 27 are of the same length and are arranged such that the steering axis 22 is still in the plane 23 in the position 22a even when the links 17 and 18 are shifted into the respective end position.
  • links 17-20 On one or more links 17-20, elements known per se from vehicle construction, such as springs 24 and / or damping elements, are arranged.
  • control arms 17 and 18 in the guides 26, 27 can be adjusted by electrical, pneumatic and / or hydraulic devices depending on the direction of travel, longitudinal or lateral accelerations or decelerations and / or the state of loading of the vehicle.

Claims (7)

  1. Suspension individuelle dans l'espace, de roues de véhicules sur rails, où l'unité roue, comprenant la roue, le palier de roue, le support de roue ne tournant pas, ainsi que, le cas échéant, un dispositif d'entraînement et/ou un dispositif de freinage, peut exécuter des mouvements de direction et/ou des mouvements à ressorts par rapport au véhicule et où les supports de roues sont reliés, de façon mobile, au support de roues de la roue située en face, par l'intermédiaire de bras oscillants, munis d'articulations à leurs extrémités, agissant comme bielles de connexion, par, ou par l'intermédiaire d'éléments intercalés, caractérisée par le fait que le point d'articulation d'au moins un bras oscillant (17-20) sur le véhicule (21) est réglable en fonction du mode de marche, tel que la marche avant ou la marche arrière, la marche tout droit ou en courbe, en freinage ou en accélération et/ou en fonction de l'état d'usure des bandages des roues.
  2. Suspension individuelle des roues dans l'espace, suivant la revendication 1, caractérisée par le fait qu'un ressort (24) est disposé sur au moins un bras oscillant (17-20) pour recevoir la charge de la roue.
  3. Suspension individuelle des roues dans l'espace, suivant la revendication 1 ou 2, caractérisée par le fait que sur au moins un bras oscillant (17-20) est disposé un amortisseur.
