Definitions

  • the invention relates to a movement system with three degrees of freedom for emulating lifting, pitching and rolling movements of vehicles of the type defined in the preamble of claim 1.
  • a known movement system with three degrees of freedom for the simulation of pitching, rolling and rolling movements in vehicles (DE 31 02 566 AI, Fig.l) has a floor-fixed base frame and a triangular platform accommodating a driver's cab or a driver's cabin of a vehicle universal joint arranged in the center of the triangle is fixed to a central column fastened to the base frame.
  • three actuators are articulated, which are supported on the base frame at three pivot points.
  • Each actuator is designed as a telescopic hydraulic cylinder.
  • the center column is also designed as a telescopic hydraulic cylinder.
  • the invention has for its object to provide a movement system of the type mentioned with three degrees of freedom To create replication of lifting, pitching and rolling movements in vehicles, which has a high lateral rigidity, so that additional measures to stabilize the movement system in the horizontal direction can be omitted.
  • the movement system according to the invention has the advantage that the synchronous drive of each plunger at two spaced-apart, mutually aligned points means that each actuator itself has a high degree of lateral stiffness and the entire movement system in the horizontal direction due to the points of attack of the three actuators on the platform, which are offset from one another by 120 °
  • the level is very stiff, so that additional stabilizers or an additional mounting of the platform on a centrally engaging central column can be dispensed with.
  • the movement system is overall simpler in construction and can be manufactured more cost-effectively. At the same time, the overall height of the movement system can be reduced.
  • the stroke range of the tappets can be easily adapted to the required conditions.
  • FIG. 1 shows a top view of a movement system with three degrees of freedom for emulating lifting, pitching and rolling movements in vehicles
  • FIG. 3 shows a side view of the actuator in the direction of arrow III in FIG.
  • FIG. 4 shows the same representation as in FIG. 3 of a modified actuator.
  • the movement system sketched schematically in FIG. 1 with three degrees of freedom for emulating lifting, pitching and rolling movements in vehicles has a platform 11 that receives a vehicle and is moved by three actuators 12.
  • the platform 11 removed here is indicated by dashed lines.
  • Each actuator 12 is fastened to a base frame 10 which is fixed to the floor and engages with a plunger 13 on the underside of the platform 11 at a pivot point 14 or 15 or 16.
  • the three articulation points 14-16 of the three plungers 13 are offset by the same circumferential angle of 120 ° from each other on a circular arc 17.
  • Fig.l only one of the three actuators 12 is shown in plan view, while of the other two actuators 12 only Articulation points 15, 16 on the platform 11 are indicated.
  • the connection between the plunger 13 and platform 11 in the articulation points 14-16 takes place via a Ball joint 18, which is only indicated schematically in FIGS. 2 and 3.
  • Each plunger 13 is designed as a U-shaped bracket with two mutually parallel bracket legs 131, 132, which are connected to one another by a yoke 133.
  • the ball joints 18 in the articulation points 14-16 are each arranged centrally on the upper side of the yokes 133 facing the platform 11.
  • a lifting drive 19 acts on each of the stirrup legs 131, 132 running at a transverse distance.
  • the two linear actuators 19 are seated on a common drive shaft 20, which can be driven by an electric motor 21 via a transmission accommodated in a transmission housing 22.
  • the drive shaft 20 is rotatably mounted in the gear housing 22 and protrudes from the gear housing 22 with its two shaft ends. Each shaft end carries an eccentric unit 23, via which the two bracket legs 131 and 132 of the tappet 13 are coupled to the drive shaft 20.
  • each eccentric unit 23 has a swivel arm 24 which is non-rotatably connected to the drive shaft 20 and which is pivotably connected to the stirrup leg 131 or 132 about a swivel axis 25 aligned parallel to the drive shaft 20.
  • the drive shaft 20 is driven by the electric motor 21 via the gearbox in such a way that it rotates from the basic position shown in FIG. executes a maximum of ⁇ 60 °, whereby the plunger 13 thereby executes an essentially linear stroke movement.
  • each eccentric unit 23 is realized by an eccentric cam 26 which is seated on the projecting ends of the drive shaft 20 in a rotationally fixed manner.

Abstract

Système à mouvement à trois degrés de liberté pour la simulation de mouvements de levage, de tangage et de roulis pour des véhicules, comprenant une plate-forme (11) recevant le véhicule et trois actionneurs (12) déplaçant la plate-forme (11), agissant sur celle-ci (11), chacun via un chariot-coulisseau (13) articulé à la partie inférieure de la plate-forme (11). En vue d'obtenir une rigidité élevée du système à mouvement dans le plan horizontal, avec un coût de fabrication avantageux, l'invention est caractérisée en ce que les points d'articulation (14-16) du chariot-coulisseau (13) sont agencés sur un arc de cercle (17), décalés mutuellement d'un même angle périphérique, et en ce que chaque chariot-coulisseau (13) est entraîné par deux systèmes de commande de levage (19) synchronisés entre eux, en prise à distance oblique l'un de l'autre, avec ledit chariot, symétriquement par rapport aux points d'articulation de ce chariot (14 ou 15 ou 16).
