Definitions

  • the invention relates to a sprung wheelset single chassis.
  • spring-loaded wheelsets which serve to support the adjacent ends of two car bodies and whose radial radial adjustment is carried out via a control device as a bisector between the car bodies.
  • a turning movement which is carried out in the air springs of the secondary stage, must be forced on the entire wheel set single running gear via the control device for the turning out movement.
  • this sometimes results in large turning movements, which are still superimposed by the dynamic transverse movements during driving operation and lead to impermissibly high loads on the air suspension bellows.
  • the object of the present invention is to upgrade spring-loaded wheelsets for higher travel speeds and low-wear bends, so that they offer the passengers appropriate driving comfort under two-axle vehicles.
  • the task is solved by the measure according to one of the claims.
  • the measures on which the invention is based are advantageously achieved by the measures shown, and a single wheel set according to the invention for higher driving speeds and a pronounced bow-friendliness is exercised, which exerts low rail straightening forces even under the worst contact geometry conditions.
  • the arrangement and the characteristics of the elements controlling the wheel set are also essential to the invention for this purpose.
  • FIG. 1 shows a first embodiment of a wheelset single chassis in a three-dimensional representation
  • FIG. 2 shows an embodiment according to FIG. 1 in the side view
  • FIGS. 1 and 2 shows an embodiment according to FIGS. 1 and 2 in plan view
  • FIG. 4 shows a side view of an exemplary embodiment for the control of a single wheel set of a two-axle rail vehicle and the control of two adjacent single wheel sets of coupled rail vehicles
  • Fig. 5 shows an embodiment for the control of a
  • FIG. 6 shows an exemplary embodiment for the control of two adjacent individual wheelset bogies of coupled rail vehicles according to FIG. 4 in a side view
  • FIG. 7 shows a further exemplary embodiment of a single wheel set in a motorized embodiment
  • FIG. 12 shows a further exemplary embodiment of a motorized wheelset single undercarriage according to FIG. 6, but in a particularly light design
  • FIG. 13 shows a schematic structure of a single-wheel gear set according to section line II-II in FIG. 2.
  • the wheel set 1 is provided at its two axle ends with a respective axle bearing 2, 2 1 , which are connected to one another via a c-shaped axle link bracket 4.
  • the wishbone bracket 4 is preferably angularly rigid, so that an axially rigid design of the axle bearings 2, 2 'can be dispensed with. As a result, any single or double row spherical, tapered or cylindrical roller bearings can be used.
  • the axle control arm 4 is supported on the one hand at its two outer ends with a stabilizer bar 5, 5 'in the vertical direction and on the other hand articulated on the chassis frame 10 via a longitudinal link 11 arranged in an approximately horizontal position.
  • all the connection points of the stabilizer bars 5, 5 'and the trailing arm 11 are designed with rubber-elastic bearings 29 which allow cardanic movement.
  • a rubber thrust spring element 3, 3 ' is arranged above the axle bearings 2, 2', which partially decouples the wheel set 1 from a control device 15, 15 'and a car body 35 leads.
  • the longitudinal characteristic of the rubber thrust spring elements 3, 3 * is designed in such a way that a small linear area has a relatively low stiffness, in which the dynamic processes of fast straight-ahead travel and ideal arch travel take place. This achieves sufficient dynamic decoupling between a wheel set 1 and a car body 35 with the advantage that no unpleasant coupling vibrations can occur between the wheel set 1 and the car body 35.
  • the longitudinal characteristic of the rubber thrust spring elements 3, 3 increases abruptly steeply after this range of low stiffness, so that when cornering without sufficient wheel / rail contact geometry the wheel set 1 is brought into the correct radial curve position by a control device 15, 15 *.
  • the course of the longitudinal characteristic of the rubber thrust spring elements 3, 3 1 is coordinated with one another with its two previously described areas so that the wheel / rail contact angle is minimized when driving in tight bends under the worst conditions, so that the wheels become out of round the wheel set 1 is not favored.
  • the progressive part of the longitudinal characteristic of the rubber thrust spring elements 3, 3 ' is ineffective at high speeds and thus does not have any disruptive effects on the running dynamics.
  • the trailing arm 11 transmits the longitudinal forces from the chassis frame 10 via the wishbone bracket 4 to the wheel set 1, whereby the articulated mounting of the trailing link 11 in rubber-elastic bearings 29 means that the trailing arm bracket 4 is only guided in the x direction and can carry out all other movements freely can.
  • a sliding plate guide 6, 6 1 is arranged above the rubber pushing spring elements 3, 3 ', which forms the parting plane for turning out the wheel set 1.
  • the sliding plate guides 6, 6 ' have a segment-like shape, so that the wheel set 1 together with the c-shaped wishbone bracket 4 can execute a centrally defined turning movement about its vertical axis and absorbs this from the primary spring step 20, 20', ie is decoupled.
  • known anti-rotation elements for example in the form of anti-roll dampers 26, 26 ', are provided for stable running straight ahead travel at high speeds between the c-shaped axle control arm 4 and the chassis frame 10 .
  • the primary spring stage 20, 20 ' carries the chassis frame 10 and, as illustrated in FIG. 13, is arranged above the slide plate guide 6, 6'. It consists of a steel coil spring set 8, 8 'standing on a spring plate 27, 27' and a rubber spring washer 9, 9 * arranged above it.
  • the spring plates 27, 27 ' are formed on their underside as counterparts to the slide plate guide 6, 6' and articulated in the direction of the c-shaped axle control arm 4 via an essentially horizontal guide rod 7, 7 'on the chassis frame 10.
  • a vertical damper 38, 38 ' is arranged between the axle bearing 2, 2' and the chassis frame 10 parallel to the primary spring step 20, 20 '.
  • the guidance of the wheel set 1 in the transverse direction is preferably carried out with a very low transverse characteristic in order to keep the unsprung masses in the transverse direction small, with the advantage of low dynamic track displacement forces. On the one hand, this allows the cornering speed to be increased and, on the other hand, it reduces the stress on the track and ultimately the maintenance costs for the route.
  • Cross stiffness of the primary spring stage 20, 20 ' consisting of the cross stiffness of the steel coil spring sets
  • Rolling moments around the x-axis are absorbed by the primary spring stage 20, 20 'and by the c-shaped wishbone bracket 4 with the stabilizer bars 5, 5'.
