Definitions

  • the invention relates to a chassis with a steering mechanism for the radial control of the wheel sets regardless of the wear condition of the rails, the steering mechanism connecting the two wheel sets both to one another and to the car body in such a way that the angle of rotation of the rubber-elastic bearings in the articulation points remain as small as possible and that the articulation on the car body is as space-saving as possible and has good decoupling.
  • EP-PS 0 389 582 discloses a bogie in which, in a first embodiment, the wheel sets are connected to one another for mutual self-control for the purpose of radial adjustment by a self-control device arranged vertically on the bogie frame.
  • the aforementioned EP-PS 0 389 582 shows in a further embodiment a bogie in which the wheelsets for the box-side forced control are connected to one another by a vertically arranged positive control device and via a pivot point which is external to the bogie frame.
  • EP-PS 0 263 283 therefore proposes a positive control device in which the wheel sets for positive control on the box side are connected to the car body by a horizontally arranged positive control device and via an articulation point on the inside with respect to the bogie frame.
  • a steering mechanism for a chassis of the type mentioned at the outset, in which the articulation on the car body takes place on the inside with respect to the chassis frame.
  • the wheel sets are initially connected to each other in a known manner by a control device, which is arranged on the outside of the undercarriage frame, essentially in a vertical plane, which is mounted in the undercarriage frame and, in relation to the latter, in an internal articulation in a second vertical plane which is offset parallel to the control device has, which is in an active connection with the car body.
  • the steering mechanism created in this way transmits through the articulation according to the invention the turning movement of both articulation points in the same plane when cornering between the car body and a chassis and converts them into opposite movements of the control devices on both chassis sides via the joint mounting of the articulation and control device.
  • This constructive design ensures that the wheel sets are controlled in a curve-radial manner regardless of the wear condition of the rails and that the angle of rotation of the rubber-elastic bearings, especially in the articulation points of the linkage, remains as small as possible, the linkage also being space-saving and without restrictions for the installation space of other units .
  • the control device reacts insensitively to the spring travel of the car body, which occurs constantly in the vertical and horizontal directions during operation, by means of the articulation shown, so that it is not inadvertently activated as a result.
  • the constructive arrangement of the articulation avoids a deterioration in the vertical dynamics and excitations of the car body.
  • the steering mechanism according to the invention is finally made for the steering mechanism according to the invention to be combined with at least one damper device in order to effectively dampen the movements from the sinusoidal motion of the wheel sets.
  • FIG. 1 shows a chassis with a steering mechanism according to the invention
  • FIG. 2 shows a chassis with a steering mechanism according to the invention, and combined with mechanical decoupling device and / or restraint means

  • a steering mechanism (2, 2 ') which consists of a control device (11, 11') and a linkage (21, 21 "), both of which are mounted in common pivot positions (6, 6 ') in the chassis frame (3).
  • the control device (11, 11') is in a first, approximately vertical plane on the outside of a chassis frame (3) on a rotating shaft (9 , 9 ') Also arranged on the rotating shaft (9, 9') and on the inside with respect to the chassis frame (3), a linkage (21, 21 ') is provided in a second, approximately vertical plane, which is connected to the car body (4th ) is in an active connection
  • the control devices (11, 11 ') on both sides of the chassis are arranged approximately parallel to each other and have a Z-shaped design, with the handlebar rods (13, 14) of the control device (11) opposite the handlebar rods (13', 14 ') of the control device ( 11 ') are aligned geometrically in the same direction, so that they can function functionally in opposite directions for the radial control of the wheel sets (5, 5') in connection with the handlebar levers (12, 12 ') via the linkage (21, 21')
  • the wheel sets (5, 5 ') in the area of their axle bearing points (7, 7') per chassis side via upper handlebars (13, 13 ') with a handlebar lever (12, 12') in an upper articulation point (15, 15 ') and connected via lower handlebars (14, 14 ') to the handlebar lever (12, 12') in a lower articulation point (16, 16 '), rubber-elastic bearings (8) being provided in all articulation points
  • the handlebar lever (12, 12 ') is attached at one end to a rotary shaft (9, 9') which is passed through the chassis frame (3) and is mounted in the pivot bearing (6, 6 ').
  • the rotary shaft (9, 9 ') has a control lever (22, 22') which in the rest position is approximately vertically upward and which, via an approximately horizontal control rod (23, 23 '), has an articulation point (24, 24'). is connected to the car body (4), with rubber-elastic bearings (8) being provided in all articulation points
  • the articulation (21, 21 ) reacts insensitively to the spring travel of the car body (4) which occurs constantly in the vertical and horizontal directions during operation due to the articulation shown, so that the control device (11, 11 ') thereby does not operate unintentionally
  • the described possibilities for arranging the articulation (21, 21 ') ultimately serve to optimally design the decoupling in each case and to avoid a deterioration in the vertical dynamics and suggestions of the car body (4).
  • FIG. 2 shows, as a further preferred exemplary embodiment, the combination of a steering mechanism (2, 2 ') according to the invention with a mechanical decoupling device (31) and / or with a damper device (39) arranged between the control device (11, 11') and the chassis frame (4).
  • the control rods (23, 23 ') of the linkage (21, 21') are connected via the articulation points (24, 24 ') to the outer levers (35, 35') of a decoupling device (31) on the car body side.
  • This consists of a connection shaft (34) which is rotatably mounted on the body (4) in two pivot positions (33, 33 '), the inner torsion-proof lever (36) of which, via the connecting rod (38) in the articulation points (37) with the chassis frame (3) connected is
  • the synergism resulting from the combination of steering mechanism (2, 2 ') and decoupling device (31) serves to decouple the steering function from the longitudinal movement, so that the steering mechanism (2, 2') remains completely unaffected by this

  • the damper device (39) can be arranged in the form of at least one damper, which preferably has a dry friction characteristic, between a control device (11, 11 ') and the chassis frame (3).
  • the combination of the steering mechanism (2, 2 ') according to the invention with a decoupling device (31) and / or damper device (39) thus advantageously supports the creation of a chassis (1) whose wheelsets (5, 5') are provided solely by the steering mechanism ( 2, 2 ") and independently of the wear condition of the rails.
  • one control device (11, 11 ') each is arranged essentially in a first vertical plane on the outside of the chassis frame (3) and this with an articulation (in relation to the chassis frame (3) in a second vertical plane) 21, 21 '), it is alternatively also conceivable to design the rotary shafts (9, 9') on both sides of the chassis as a one-piece connecting shaft, on the outer ends of which the control devices (11, 11 ') are arranged in a rotationally fixed manner.
  • control devices (11, 11 ') which are constructed in a z-shape, are arranged geometrically in opposite directions with respect to the arrangement of their handlebar rods (13, 14 and 13', 14 ') on the handlebar levers (12, 12') on both chassis sides.

Abstract

Dans un mécanisme de guidage utilisé pour commander radialement en courbe les essieux montés du bogie d'un véhicule sur rails, les deux essieux montés sont mutuellement reliés par des dispositifs de commande en Z montés à l'extérieur du châssis du bogie. Chaque dispositif de commande en Z est fonctionnellement relié à la caisse de wagon par une articulation. Les dispositifs de commande (11, 11') sont montés des deux côtés du châssis (3) du bogie dans un premier plan vertical, à l'extérieur du châssis (3) du bogie, et au moins une articulation (21, 21') parallèle au dispositif de commande correspondant est montée dans un deuxième plan vertical décalé vers l'intérieur par rapport au châssis (3) du bogie. Les essieux montés (5, 5') sont radialement réglés dans les virages uniquement en fonction de l'angle de torsion qui résulte lorsqu'un virage est amorcé, indépendamment de l'état d'usure des rails. L'association de dispositifs de commande (11, 11') montés dans un premier plan vertical et d'articulations (21, 21') montées dans un deuxième plan vertical permet de commander les essieux montés indépendamment de l'état d'usure des rails et de réduire fortement l'usure des boudins et des flancs des rails causée par les forces de guidage dans le cas d'une commande automatique.
