Definitions

  • the present invention relates to a joint arrangement for a coupling, in particular for a joint coupling or a central buffer coupling, for articulating two adjacent car bodies of a multi-unit vehicle, in particular a rail vehicle, with a first joint part, a second joint part and a hinge pin, wherein the first and the second hinge part by means of the hinge pin to an articulated by the hinge pin common pivot axis cooperate.
  • Such a joint arrangement is known for example in the form of an articulated coupling from rail vehicle technology.
  • the object of such a joint assembly used in a joint coupling is to bind adjacent car bodies of a multi-unit vehicle body to each other while allowing for a defined movements between the car bodies, and on the other hand, if necessary, to restrict certain degrees of freedom.
  • the joint arrangement often takes over the coupling of two car bodies in the vehicle longitudinal direction more functions, such as the support of a part of the weight or the steering of the car body.
  • each articulated coupling designed as a hinge assembly associated with the first car body first hinge part and a second car body associated second hinge part on.
  • associated joint part used in connection with joint couplings are also joint parts or articulated arms to understand that are attached to the relevant car body rigid but also almost rigid. This also includes such joint parts or articulated arms, which are arranged with a certain play on the car body in question, which is the case, for example, when the joint part is attached via an elastomeric body to the car body.
  • a coupling arrangement generally has per car body on the front side of the car body concerned via a linkage mounted coupling rod at the front, the articulation opposite end of a coupling head can be provided.
  • the respective coupling rods are rigidly connected to each other, while the respective carriage box-side ends of the coupling rods are articulated on the above-mentioned linkage to the respective car bodies.
  • a through-coupling coupling arrangement thus has - in contrast to the aforementioned joint coupling - not a common pivot axis, but two different pivot axes.
  • the respective end of the coupling rod is pivotally mounted on the bearing block or on the front side of the car body, which is usually done by means of a hinge assembly.
  • the first hinge part is a part of the bearing block, while the second hinge part forms the end of the coupling rod.
  • joint arrangements are used in so-called bendable coupling arrangements, wherein in the coupling rod of this coupling arrangement, a joint arrangement is integrated, so that the coupling rod can be bent if necessary.
  • the first and second hinge part each represent a part of the coupling rod.
  • a joint arrangement further comprises a hinge pin, which connects the respective joint parts with each other in such a way that they can interact in an articulated manner about a common pivot axis defined by the hinge pin.
  • the function of the hinge pin in an articulated coupling is primarily to transmit tensile and compressive forces of the universal joint. In detail, such tensile and compressive forces transferred from one of the two joint parts on the hinge pin and forwarded via this hinge pin on the counterpart of the joint assembly. In order to allow an articulated interaction of the two joint parts, these joint parts must be able to pivot about the pin axis to each other.
  • the primary function of the hinge pin is to provide tensile and impact forces transmitted via the coupling rod of the coupling from adjacent car bodies to the coupling rod acting as one of the two hinge parts serves to transmit over the hinge pin on the bearing block, which serves as the other joint part.
  • the hinge pin is used to pivotally connect the two partial coupling rods together.
  • bearings are usually provided in the joint assembly, the absorb and absorb these forces.
  • articulated arrangements designed as spherical joints absorb the longitudinal, transverse and vertical forces which occur during the travel of the multi-unit rail vehicle between the adjacent vehicle bodies.
  • joint arrangements which additionally have a roller bearing and an elastomer joint.
  • Such trained joint arrangements makes it possible to record on the rolling bearing which adjusts during cornering horizontal deflection, during which adjusting when passing through a depression or when driving over a hilltop angle of inclination is absorbed by the elastomer joint.
  • the invention is therefore based on the object, a hinge assembly for a clutch, in particular for a universal joint or a central buffer coupling, for articulated connection of two adjacent car bodies, which is perfectly functional even at low ambient temperatures.
  • a joint arrangement of the aforementioned type wherein the joint assembly further comprises a heater, whose at least one heating element is introduced into a recess of the hinge pin and covered to the outside. It is envisaged that upon activation of the radiator, the heat generated in the hinge pin will be transmitted via the outer surfaces of the hinge pin in the bearings of the joint assembly. By taking place via the heating element heat supply, the icing of the bearings can be prevented or resolved even at low ambient temperatures, so that the joint assembly is always functional. With the solution according to the invention, the joint arrangement of ice and snow can thus be reliably kept free even in winter and its function can be ensured.
  • the radiator in a recess of the hinge pin, and then cover it to the outside by welded or soldered cover elements. Furthermore, it is conceivable to glue or solder the heater in the recess itself. In this case, it must be ensured that the soldering of the radiator takes place without cavities in the filling material, in order to prevent local overheating of the radiator in such cavities, or that, on the other hand, moisture can penetrate during operation, which often leads to corrosion. Furthermore, it is conceivable to use as the outer cover of the radiator a silicone material which forms the outer cover, and which in the backfilling is, for example, a closable single-component material which crosslinks and cures under the action of atmospheric moisture at room temperature.
  • cover elements as cover, which are introduced into adapted countersinks and connected to the hinge pin, preferably by brazing.
  • the fact that the hinge assembly according to the invention is designed so that the radiator is introduced into the recess of the hinge pin even after mechanical completion of the hinge assembly or the hinge pin, the risk of damage to the radiator including its supply line during assembly of the hinge assembly is significantly reduced.
  • the recess of the hinge pin is made to fit the cross section of the radiator.
  • radiators per hinge pin instead of a single radiator, wherein either a separate recess is provided for each radiator, or a single recess is designed to accommodate a plurality of radiators.
  • a separate recess is provided for each radiator, or a single recess is designed to accommodate a plurality of radiators.
  • the invention provides that the radiator is releasably secured to the hinge pin.

  • releasable fastening means for example, head plates are conceivable, with which the radiator is fixed to the hinge pin.
  • the radiator after it has been introduced into the recess of the hinge pin is fixed according to one of the joint parts.
  • the recess which is designed to receive the radiator in the hinge pin is preferably designed as a linear bore formed, which extends substantially parallel to the longitudinal axis or on the longitudinal axis of the hinge pin itself.
  • the recess or the recesses as a groove in form the hinge pin, which are then covered by an inserted front plate.
  • Such a groove solution is for example in question when drilling out the recess in the hinge pin, for example, due to the hardness of the steel bolt used at the hinge pin, poses problems.

  • the joint arrangement furthermore has a bearing, in particular a spherical-elastic bearing and / or an angular-joint bearing, through which the hinge bolt passes.
  • a bearing in particular a spherical-elastic bearing and / or an angular-joint bearing, through which the hinge bolt passes.
  • This embodiment has the advantage that the heat introduced by the radiator integrated inside the hinge pin can penetrate into the bearing quickly and uniformly and can be distributed there.

  • the hinge pin further comprises a head portion and a pin lock, which cooperate such that the bolt is held in the region of the storage of the first and second hinge parts.
  • Conceivable here would be, for example, to perform the bolt cylindrically, wherein further at least one groove for receiving a shaft securing ring is inserted in the bolt.
  • the hinge pin has different cylindrical diameters in the region of the bearing of the first and second hinge parts, wherein the different diameters are designed so that the bolt is held in the region of the bearing of the first and second hinge parts.
  • the primary task of the hinge pin is to transfer the tensile and compressive forces transmitted by one of the two hinge parts to the hinge pin to the counterpart of the hinge arrangement.
