Definitions

  • the invention relates to a device for articulated connection of two car bodies of a multi-unit rail vehicle, in which one of the car bodies is supported in all loading conditions with a substantial proportion of its weight on the device on the other car body, which is connected to at least one chassis.
  • the articulated train arrangement i. the connection of the individual cars of a train by a single, only rotationally movable joint is a proven design principle in rail vehicle construction.
  • one single bogie is sufficient for each wagon crossing, which means that the number of bogies in the train can be significantly reduced even while keeping their distance.
  • the relative movements at the transitions of the car due to the limited degrees of freedom are much lower, which significantly simplifies the implementation of transitional devices.
  • Such a high rigidity is generated either by the type of joints that do not have the corresponding degree of freedom, or by the connection of two car body ends to a joint area arranged in the common bogie (eg Jakobs-type with separate secondary spring per car body corresponding to the railcar trains series 423 to 426 of the German Railways AG).
  • Due to the rigid coupling of the car bodies it is possible to compensate for track position disturbances and overhanging ramps worse than for single cars, which can lead to wheel derailment critical wheel unloadings.
  • all component and assembly tolerances are summed over the train length, so that a final adjustment for adjusting the wheel loads on the entire tractor may be required, which places significant demands on the metrological equipment.
  • a possible solution to the above-described problem is a soft around the longitudinal axis of the joints in conjunction with a clear assignment of the bogies to exactly one car body - at least with respect to the roll support.
  • This is achieved, for example, with the one-stage high-speed train TGV, which is made possible by elastomere joints that can be rotated on all sides and a connection of the anti-roll bars to only one body.
  • TGV high-speed train
  • Jakobs bogies in total always have a bogie more than car bodies, obviously the assignment of Wankabstützung each bogie to a car body whose mass corresponds exactly to the load of this bogie, not consistently possible.
  • the invention has for its object to make a device of the generic type so that the aforementioned disadvantages of the existing vercardenfin designs are avoided.
  • This object is achieved in that the torsional stiffness between the car bodies around the vehicle longitudinal axis compared to the Anbindesteiftechnik the car body to his chassis is low, occurring in the vehicle transverse direction forces are transmitted approximately at the height of the center of gravity of the car body connected to the chassis.
  • the device according to the invention is characterized in that the rolling moments are distributed in the same distribution on the bogies as the vertical loads, so that the tipping stability of all bogies is optimally utilized. Since the transmission of the transverse forces between the car bodies is at the level of their centers of gravity, the stationary effect on the chassis at unbalanced lateral acceleration for an attached via the articulated car body mass is equal to a wankfest coupled. The dynamic parts of the rolling forces are not transmitted by the system itself. However, it is not a problem to couple the car bodies by intermediate dampers. Unlike elastic or kinematic coupling, as in the existing articulated trains described above, viscous dampers avoid tensions due to tolerance problems because they are self-adjusting.
  • a car body 1 belonging to an articulated train is connected to at least one chassis 3.
  • the other car body 2 which has a support arm 4 facing the car body 1 is supported on the car body 1 with a substantial proportion of its weight via the connecting device in all loading states. Because a transmission of longitudinal forces between the car bodies 1 and 2 at the height of their centers of gravity for reasons of structural load usually not useful, a structural separation of the force components is preferred in the embodiments.
  • the longitudinal forces are transmitted at the level of the undercarriage of the two car bodies 1 and 2, for example by a loadable on train and pressure, articulated coupling rod 8 - see Fig. 1 and 3 - or by means of a tie rod 10 and at least one effective pressure direction buffer 9 (see FIG. see Fig. 6).
  • a corresponding embodiment is conceivable as elastic support 5, for example in the form of shown in Fig. 2, wedge-shaped rubber layer springs whose stiffness center of gravity is at the height of the center of gravity S of the car bodies 1 and 2.
  • a suspension of the car body 2 can take place via a link 6 having Gelenkgetriebe whose instantaneous center is at the height of the box center of gravity S, as shown in FIGS. 3 and 4.
  • the transverse force transmission can also take place directly in the amount of the center of gravity S by transverse stops 7 (FIG. 5) or correspondingly arranged handlebars.
  • a complete articulated train with one of the connecting devices explained here can have two car bodies 1 forming the ends of the train, which are supported at their two head sections on a respective chassis 3. Between such Endwagenkarsten 1 arranged in basically any number average car bodies 2 can rest on only one chassis 3, which is located below the side facing away from the connecting device, not shown end portion of the corresponding car body 2. However, it is also possible to provide the or the middle car bodies 2 of the articulated train free of trolleys 3 as so-called floating car bodies, in which each of the car ends one of the connecting devices according to the invention is detracted.
