Definitions

  • the invention relates to a rail-bound low-floor vehicle which has at least two car bodies coupled by a joint and a single-axle chassis which is arranged next to the joint below a car body and which is essentially formed from a frame and two wheels.
  • a low-floor vehicle with the aforementioned features is known from the magazine “Stadt mich" 5/90, see in particular page 22, picture 11 and page 24, picture 17.
  • the middle car body of the three-part vehicle shown rests on single-axle single-wheel chassis, which are each arranged next to a joint .
  • Both wheels of the undercarriage are individually pivoted on a frame and can be connected to each other by a tie rod.
  • the tangential setting of the wheels when cornering takes place via the forces acting at the wheel contact point; the position of the chassis frame in relation to the car body does not change.
  • Such independent wheel trolleys are well suited for low-floor vehicles, since a deep central aisle of the vehicle floor can protrude into the space between the individual wheels, the wheels penetrating the side floor sections and being covered with wheel arches below the passenger seats. In comparison to a conventional wheel set, however, a single wheel arrangement is more complex.
  • the invention has for its object to design a low-floor vehicle of the generic type in the sense of an alternative to a single wheel chassis such that radial settings of the wheels and a low-lying floor can be achieved even when using a simple wheel set.
  • the undercarriage and the body are connected to one another via a vertical axis of rotation arranged in the longitudinal center of the vehicle and with a longitudinal distance from the center axis of the two wheels, the space above a wheelset shaft taking up the center axis being free of components of the undercarriage. It is therefore essential that the vertical axis of rotation extends in front of or behind a wheelset shaft that occupies the center axis, so that the space above this shaft can be used for the lowered central aisle of the vehicle floor.
  • two car bodies 1 and 2 are coupled by a joint 3, which enables these car bodies to rotate and bend relative to one another.
  • a single-axle running gear 4 which has a frame 5 and one usually formed from two wheels 6 and a shaft 6a ' Has wheelset.
  • the bearings 6b of the wheel set are supported against the chassis frame 5 with the interposition of primary springs 11 (see also FIG. 2).
  • the primary springs 11 are rubber-metal elements which are arranged at an angle to one another, so that longitudinal and transverse forces can also be transmitted between the wheel bearing 6b and the chassis frame 5 without additional components. Only the vertical dampers 16 shown in FIG. 1 are assigned to the primary springs 11.
  • connection of the car body 1 and the chassis 4 takes place via a vertical axis of rotation 8 of a pivot bearing on the car body 1, which is designed as a ball socket 8a in the exemplary embodiment two wheels 6 and their wheelset shaft 6a '.
  • a wishbone 9 is held on the one hand on the vertical axis of rotation 8 and attached via its two other ends in a horizontal bearing 5a to the chassis frame 5.
  • the bearings 5a contain elastic bushings which are stiff in the longitudinal direction of the vehicle, but allow cushioning in the transverse direction of the vehicle, a transverse damper 17 being effective.
  • the wishbone 9 engages under the wheelset shaft 6a ', so that the free space above this shaft can be used for a central aisle 13a of the low-lying vehicle floor 13.
  • the secondary springs 12 consist of a combination of coil and rubber springs and also work as flexicoil springs when the chassis 4 is pivoted about the vertical axis of rotation 8.
  • a steering linkage 10 which according to FIG. 1 has a link-side link 10b, an intermediate lever 10c and a link-side link 10a.
  • the handlebar 10b is connected on the one hand in the region of the joint 3 to the body 2 and on the other hand to the intermediate lever 10c which is mounted on the body 1.
  • the suspension arm 10a engages approximately in the middle on the intermediate lever 10c; its other end is connected to the chassis frame 5. Because of the vertical spring travel, it goes without saying that 10 ball joints are arranged within the steering linkage. For reasons of space, the control arm 10a also runs below the axle shaft 6a '.
  • the damper 14 shown in FIG. 1 is effective when the chassis 4 is pivoted.
  • Both the wishbone 9 and the steering linkage 10 are fastened to the body 1 and to the chassis frame 5, the elastic bearings 5a holding the wishbone 9 being stiff in the longitudinal direction of the vehicle. As a result, 12 identical up and down movements are achieved when the secondary springs are deflected, and steering errors are thus avoided.
  • a disc brake device 15 shown in FIGS. 1 and 3 is not shown in FIG. 2 for the sake of clarity.

Claims (9)

  1. Véhicule ferroviaire à plancher bas qui présente au moins deux superstructures (1,2) accouplées par une articulation (3) et un dispositif de roulement à un essieu (4) placé à côté de l'articulation (3), sous une superstructure (1), qui est essentiellement formé par un châssis (5) et deux roues (6), caractérisé en ce que le dispositif de roulement (4) et la superstructure (1) sont reliés entre eux par un axe de rotation vertical (8) coupant l'axe longitudinal (7) du véhicule et disposé avec un écart longitudinal (L) par rapport à l'axe central (6a) des deux roues (6), sachant que l'espace au-dessus d'un arbre d'essieu monté (6a') à travers lequel s'étend l'axe central (6a) ne contient aucune pièce du dispositif de roulement.
  2. Véhicule à plancher bas selon la revendication 1, caractérisé en ce que, pour transmettre des forces longitudinales et transversales, est prévu un levier triangulé (9) passant sous l'arbre de l'essieu monté (6a') des roues (6), qui est fixé par deux extrémités au châssis (5) du dispositif de roulement par le biais de paliers horizontaux (5a) et par sa troisième extrémité à l'axe de rotation vertical (8).
  3. Véhicule à plancher bas selon la revendication 1 ou 2, caractérisé en ce que l'axe de rotation vertical (8) est constitué par un coussinet sphérique (8a) fixé à la superstructure (1).
  4. Véhicule à plancher bas selon l'une des revendications 1 à 3, caractérisé en ce que le dispositif de roulement (4) peut être réglé dans la direction radiale par une timonerie (10) en fonction des mouvements des superstructures (1, 2) roulant sur une voie en courbe.
  5. Véhicule à plancher bas selon la revendication 4, caractérisé en ce qu'un levier (10a) faisant partie de la timonerie (10) et relié au dispositif de roulement se trouve sous l'arbre de l'essieu monté (6a') des roues (6).
  6. Véhicule à plancher bas selon l'une des revendications 1 à 5, caractérisé en ce que le dispositif de roulement (4) présente un niveau de suspension primaire et un niveau de suspension secondaire.
  7. Véhicule à plancher bas selon la revendication 6, caractérisé par des ressorts primaires (11) disposés en angle l'un par rapport à l'autre qui transmettent des forces longitudinales et radiales entre un roulement de roue (6b) et le châssis (5) du dispositif de roulement.
  8. Véhicule à plancher bas selon la revendication 6 ou 7, caractérisé en ce que, directement entre le châssis (5) du dispositif de roulement et la superstructure (1), sont disposés des ressorts secondaires (12) pouvant être sollicités comme des ressorts à boudin flexibles.
  9. Véhicule à plancher bas selon les revendications 2,4 et 8, caractérisé en ce que le levier triangulé (9) et la timonerie (10) sont fixés aux mêmes éléments - superstructure (1) et châssis (5) du dispositif de roulement -, de sorte que, lorsque les ressorts secondaires (12) se compriment, ces éléments (1, 5) effectuent des mouvements ascendants et descendants identiques, ce qui permet d'éviter des erreurs de direction.
