Definitions

  • the invention relates to an arrangement with an elongated, hollow body-shaped housing part and a rod-shaped component according to the preamble of claim 1.
  • the rod-shaped component is inserted in its longitudinal direction into the housing part and fixed to the housing part, the rod-shaped component and the housing part having openings for the positive reception of a generally bolt-shaped driving device to be inserted in the transverse direction of the rod-shaped component.
  • two components here the elongated, hollow body-shaped housing part and the rod-shaped component, have to be coupled with easily detachable connections in order to transmit forces acting in the longitudinal direction of the rod-shaped component.
  • positive power transmissions are generally preferred.
  • the elongated, hollow body-shaped housing part can be at least a section of a base frame of the rail vehicle and the rod-shaped component can be a coupling rod.
  • transverse wedges For the positive connection of an elongated, hollow body-shaped housing part and a rod-shaped component, it is also known to use transverse wedges. In contrast to a cylindrical bolt made of solid material, such transverse wedges are insensitive to dimensional and storage deviations of the components, as they can create a preload over a certain working range.
  • the disadvantage of using transverse wedges is that each transverse wedge only transmits forces in one direction and is therefore only effective against a fixed stop or in a double arrangement.
  • tolerance against dimensional deviations or plasticization when driving in the transverse wedges in conjunction with flat wedge angles requires correspondingly long nominal projections of the transverse wedges on both sides of the elongated, hollow body-shaped housing part.
  • the invention is based on the object of further developing an arrangement of the type mentioned in such a way that the rod-shaped component is fixed with as little play as possible within the elongated, hollow body-shaped Housing part is realized, taking into account dimensional tolerances of the components involved.
  • a load is transferred from the rod-shaped component via one of the beams in each load direction in a form-fitting manner to the elongated, hollow body-shaped housing part.
  • the bars of the bolt-shaped driving device running in the transverse direction of the rod-shaped component and the elongated, hollow-body-shaped component are preferably interlocked.
  • This arrangement enables a single, continuous opening in both the elongated, hollow-body-shaped housing part and in the rod-shaped component, which is each loaded outwards, while in a non-interlaced arrangement the beams are either in the elongated, hollow-body-shaped housing part or in the rod-shaped component
  • An intermediate bridge would have to be provided, which would be loaded on both sides. This would require a multiple length of the arrangement.
  • a pressure piece of the first beam provided for contact with contact surfaces of the rod-shaped component forms a main body of the first beam and end-side cylindrical functional surface sections of the first beam the housing part a first load path for transmitting longitudinal forces acting on the rod-shaped component in a first direction and a pressure piece of the second beam provided for contact with contact surfaces of the rod-shaped component, a main body of the second beam and end-side cylindrical functional surface sections of the second beam to the housing part a second Load path for transmitting longitudinal forces acting on the rod-shaped component in a second direction opposite the first direction, the wedge-shaped contact surfaces of the beams adjoining the housing part on the end-side, cylindrical functional surface sections in the insertion direction of the bolt-shaped driving device.
  • the bolt-shaped driving device can have a drive at one of its ends for moving the beams in the transverse direction of the rod-shaped component.
  • the drive can in particular be designed as a cover that can be screwed against the housing part. Screwing the cover into the associated opening of the housing part then causes the bolt-shaped driving device to move in the transverse direction of the rod-shaped component until the bolt-shaped driving device reaches its tensioned operating position while engaging in the openings of the housing part.
  • the wedge-shaped contact surfaces of the housing part can be limited in their area of action by a transition to the functional surface sections running in the transverse direction of the rod-shaped component in such a way that in a final phase of a transverse movement of the bolt-shaped Driving device in its operating position no longer changes relative position of the bar.
  • each beam is connected to its pressure piece via an elastic element.
  • the elastic elements are designed as rubber layers inserted or vulcanized between the respective beams and the pressure pieces assigned to them.
  • the pressure pieces are made in one piece with the associated beams.
  • the end contact surfaces of the bars can be provided for direct contact with the material of the housing part, so that in this case the bars engage directly in the intended opening edge sections of the housing part.
  • the end contact surfaces of the beams can rest on an intermediate piece which is inserted into one of the opening edge sections of the housing part.
  • Such an intermediate piece can in particular be designed as a socket with a cylindrical fit in the opening of the housing part.
  • the bolt-shaped driving device to engage at one end directly into an opening edge section of the housing part, for example at its drive end, and to engage at its other end in a socket which is inserted into the associated opening edge section of the housing part.
  • a socket in only one of the opening edge sections of the elongated hollow body-shaped housing part
  • wedge-shaped contact surfaces that engage directly on the housing part can be designed in such a way that the cylindrical area is already reached at the end before the wedge-shaped contact surfaces come into engagement with the socket.
  • prestressing forces and the contact surfaces between the pressure pieces of the beams and the rod-shaped component can be designed in such a way that the bolt-shaped driving device can be displaced in a plane perpendicular to the longitudinal direction of the rod-shaped component, i.e. H. Transverse mobility of the rod-shaped component in the housing is made possible after assembly.
  • the rod-shaped component is preferably designed as a coupling rod and the housing part as part of a base frame of the rail vehicle.
  • Figure 1 shows an arrangement with an elongated, hollow body-shaped housing part 1 and a rod-shaped component 2, which is inserted into the housing part 1 in its longitudinal direction.
  • the elongated, hollow body-shaped housing part 1 would be identified with a base frame and the rod-shaped component 2 with a coupling rod of such a vehicle.
  • the Rod-shaped component 2 is fixed in its operating position in the housing part 1 with the aid of a bolt-shaped driving device 3 which is cylindrical in cross section at its two outer ends.
  • the rod-shaped component 2 has a through opening 4, which is assigned to a central part of the bolt-shaped driving device 3.
  • the elongated, hollow body-shaped housing part 1 has a continuous opening 5 with opening edge sections 5.1, 5.2.
  • opening edge sections 5.1, 5.2 are designed in their position and extent such that the bolt-shaped driving device 3 can be inserted into the openings 4, 5 along an axis 6 in the transverse direction of the rod-shaped component 2, namely while exercising a Prestressing in the longitudinal direction of the rod-shaped component 2.
  • a bushing 7 is inserted into the opening edge section 5.1, so that the bolt-shaped driving device 3 does not interact directly with the material of the housing part 1, but via the bushing 7.
  • the bolt-shaped driving device 3 has two interlocked beams 9, 10 aligned in the transverse direction of the rod-shaped component 2. Each of these beams 9, 10 is associated with a pressure piece 11, which is connected to a main body of the respective beam 9, 10 via an elastic rubber layer 12, for example by vulcanization.
  • the pressure pieces 11 rest directly on assigned contact surfaces of the rod-shaped component 2 to form a positive connection.
  • the rubber layers 12 enable any dimensional tolerances of the components involved to be compensated for.
  • Both ends of the beams 9, 10 each show wedge-shaped contact surfaces 9.1, 9.2 or 10.1, 10.2 for interaction with the elongated, hollow body-shaped housing part 1.
  • the wedge-shaped contact surfaces 9.1, 10.1 lie on the side of the bolt-shaped driving device 3 opposite the cover 8 Inside of socket 7.
  • functional surface sections 9.3, 10.3 of the beams 9, 10 adjacent to the wedge-shaped contact surfaces 9.1, 10.1 of the socket 7 are, in contrast, cylindrical.
  • the functional surface sections 9.4, 10. 4 of the beams 9, 10 adjoining the cover 8 are also cylindrical and lie against an inside of the opening edge section 5.2 in the operating position of the bolt-shaped driving device 3.
  • the wedge-shaped contact surfaces 9.2 and 10.2 adjoin these cylindrical functional surface sections 9.4, 10.4 in the direction of the opening edge section 5.1.
