Definitions

  • the invention relates to a universal joint for vehicle units of rail vehicles according to the preamble of claim 1.
  • Joint connections between multiple units are often based on the principle fork-and-fork constructions. These are usually a bolt as Connecting element inserted through holes in the fork cheeks and the tab. When coupling rail vehicles this type of mounting is in general not possible, because the required alignment of the holes of tab and fork cheeks can not be made. That's why the fork cheeks not drilled, but horizontally provided with half shells, in which the stuck in the tab hole bolts can be stored. As in the shared camp he is a counterpart, a screwed second half-shell, held down and fastened.
  • This coupling device for the ends supported on a common bogie two articulated vehicle units consists of a attached to the one vehicle unit, having two lateral fork cheeks Clevis, one attached to the other vehicle unit, between the two fork cheeks inserted connecting strap and a Coupling pin with arranged in the connecting plate spherical bearing.
  • the spherical bearing is firmly in the connecting plate with the coupling pin arranged.
  • Both fork cheeks have horizontally split, off a lower, fixed and an upper, detachable bearing shell existing bearings on, over which the coupling pin is clamped in the fork cheeks.
  • a another fork-flap construction shows the DE 44 04 878 C1.
  • the invention is therefore based on the object, the known universal joints, which are based on the fork-flap principle, form such that the Determination of Sphotelenkbolzens can take place in a defined position.
  • An advantage of the invention lies in a simple coupling and uncoupling of Vehicles, depending on the type of vehicle the most favorable direction of the coupling process can be realized. Furthermore, the invention allows a backlash-free, clear bolt fastening in the fork.
  • the Sphotelenkbolzen is stored in fixed clutch fork half-shells either from above or horizontally-longitudinally or introduced from below and thereby receives a first centering.
  • the actual mounting of the bolt is done by pins in holes the fork cheeks of the clutch fork, not in screwed clamp connections.
  • With the help of a conical seat is a kind of extension of the bolt achieved, as in the conventional fork-tab connections, passes through all holes in alignment. Center and clamp the cones the Sphotelenkbolzen and keep it in a unique position.
  • the bolt is considered to be similar to a "between points" to be rotated workpiece.
  • the figures show a arranged on a vehicle unit clutch fork 1 with the two side fork cheeks 1a and one on the other vehicle unit arranged coupling tab 2 and arranged therebetween Spherical hinge pin 3.
  • a spherical bearing of the coupling tab 2 takes the in its central region spherically formed part of the Sphotelenkbolzens 3 on.
  • the fork cheeks 1a of the clutch fork 1 have half shells 4 for the spherical hinge pin 3 aligned, outer holes 5.
  • the attachment of the bolt ends is carried out by introduced into the holes 5 Pins 7, with their conical, front part 8 in the body the spherical joint pin 3 located, conical holes 6 engage.
  • the pins 7 are connected to a flange 9, which by screws 11 and Clamping sleeves 10, the number of which is variable depending on the requirements, on the fork cheeks 1a determined. By the clamping sleeves 10, the screws are 11th kept free of lateral forces.
  • the pressure element 12 is expediently designed as a pressure screw in the Lid 13 guided in a centrally arranged threaded bore 14 and against self-loosening on and opposite the lid 13 by means of securing element 15, in particular lock nut is secured.
  • a rotationally fixed, axial guidance of the pin 7 in the cover 13 is via a tongue and groove connection reached.
  • the spring 16 is associated with the pin 7 and attached to this or as an integral or molded extension thereof formed and the groove 17 is disposed in the interior of the lid 13.
  • the Assignment is also executable vice versa.
  • the screws 11 for connecting the pin 7 with the lid 13 and the Screws 11 for pressing the lid 13 of the fork cheek 1a point preferably the same bore diameter as the screws 11 to Set the lid 13 on the fork cheek 1a.
  • the screws 11 for fixing the lid on the fork che 1a correspond in number and execution of the screws 11 for connecting the pin 7 with the lid 13 and the screws 11 for pressing the lid thirteenth from the fork cheek 1a.
  • four screws 11 are to be fastened the lid 13 is used. Of these 4 screws 11 found during disassembly 2 screws 11 for connecting the pin 7 with the lid 13 and second Screws for pushing the deck 13 (with screwed pin 7) of the Fork cheek 1 a use.
  • the releasable fastening means screws 11
  • screws 11 When mounting the tapered pin 7 by means of a separate cover 13th the releasable fastening means (screws 11) can be a unique connection between the lid 17 and fork cheek 1a regardless of the function of clamping the pin 7.
  • the function of the terminal is over the Druckelelement 12 generates.
