Definitions

  • the invention relates to a bogie of a rail vehicle, in particular rail vehicle bogie, with the features of the preamble of claim 1 and a rail vehicle with such a bogie.
  • Such a bogie usually has a frame of two longitudinal members and mounted in the frame wheelsets and motors for driving each one of the wheelsets.
  • the running in the direction of travel side members are connected to one another via one or two transverse to the direction of travel cross member.
  • Such cross members are arranged as head cross member at the end portions of the side members, i. in or against the direction of travel on the outside of the adjacent wheelsets.
  • train-push rod which is arranged between the vehicle frame and a relative to the Endrad accounts the bogie eccentric center cross member.
  • the disadvantage here is that a bogie-side joint of the train-pressure rod has a large distance from the center of the boring movement of the bogie about its vertical axis. This occurs when turning the bogie relative to Vehicle frame instead of a pure rotary motion always in addition to a longitudinal and transverse movement to the latter.
  • a bidirectional alignment of the traction motors to the ends of the bogie down requires even more space than in unidirectional traction motor assembly and consequently a further increased moment of inertia around the bogie vertical axis. This results in disadvantageously large quasi-static vertical paths of the primary springs due to a tensile force.
  • Bidirectional alignment of the traction motors toward the center of the bogie has a combination of the disadvantages, as mentioned above, for driven bogies with longitudinal force transmission to the vehicle frame via a pull-push rod.
  • the invention is therefore based on the object to propose a bogie, which has an alternative embodiment and thus offers advantageous properties, in particular with regard to the installation in a rail vehicle and the driving behavior during operation.
  • the available space in the bogie area should be better used.
  • train-pressure rod causes the pivot point of the bogie around the vertical axis or vertical axis in the area "the geometric center" between the two sets of wheels remains, while the transmission of tensile and compressive forces on the vehicle frame in the vehicle longitudinal direction offset from it.

  • the train-pressure rod so in particular also causes the fulcrum of the bogie remains about its vertical axis in the area between the two sets of wheels, while the transmission of tensile and compressive forces on the vehicle frame is offset in the vehicle longitudinal direction.
  • the train-push rod is connected according to a further preferred embodiment with the main cross member of the frame of the bogie so articulated that the joint is arranged close to the center of the Auscardterrorism the bogie about its vertical axis.
  • a preferred embodiment is that the train-push rod leads below a / the wheel axle of such a wheel along along to a / the structural element of a vehicle frame.

  • connection component is in particular a vehicle-side joint body or a joint portion.
  • connection component is formed as part of the pull-push rod, e.g. as a hinge eye, but can also be structurally an independent component, which is connected or connectable to the pull-push rod and / or with such a structural element.
  • a connection is preferably designed as a hinge connection, a coupling or optionally also a rigid connection.
  • the frame consists in particular of outside longitudinal members of the bogie, wherein the at least two wheelsets are arranged on and / or between the longitudinal members.

  • connection component is arranged vertically or from a vertical view in the longitudinal direction of the frame or in the bogie longitudinal direction within or below the frame.
  • the structural element of the vehicle frame which accommodates or stores in particular the vehicle-internal or vehicle-centered end of the push-pull rod as a connection component, extends partially or completely into the longitudinal extent of the bogie in the vehicle longitudinal direction. This is especially true when the junction is arranged from the perspective of the frame structure of the bogie within or below a plane defined by the frame structure of the bogie plane.
  • the frame has in addition to the central cross member at least one further cross member, which is formed from view of the central cross member beyond an axis of one of the wheelsets between two longitudinal members of the frame, wherein the connection component vertically or out vertical view is arranged in bogie longitudinal direction between the central cross member and the other cross member.
