Definitions

  • the invention relates to a coupling component for a coupling for the mechanical coupling of track-bound vehicles, in particular for a coupling of the Scharfenberg type; also a clutch arrangement with such a clutch component.
  • Coupling arrangements for mechanically connecting track-bound vehicles are previously known in various designs from the prior art.
  • the couplings include a coupling rod for at least indirect articulation and/or attachment to a car body and a coupling head with coupling elements, in particular a coupling lock.
  • the coupling heads are characterized on the front by a profile made up of a funnel and a cone.
  • the cones of the two coupling heads to be coupled with one another lie in the opposite funnels of the respective mating coupling and connect the coupling heads to one another by means of the coupling locks arranged in the respective coupling heads.
  • the coupling lock is designed as a rotary lock with a coupling eyelet and a frog, the frog being rotatable about a main axis at least between a coupling-ready position and a coupled position.
  • the frog has a mouth for receiving a corresponding second end of a coupling eyelet of an opposite coupling head.
  • Such coupling arrangements are characterized by an at least partially modular structure consisting of a coupling head with a coupling head housing and an end plate and coupling rod connected thereto.
  • the coupling head is releasably connected to the coupling rod, for example by means of a shell socket connection.
  • the coupling head is at least partially integral with a coupling rod by the integral design of the coupling head housing and the coupling rod as a one-piece cast part.
  • Coupling heads with a detachable end plate for a rail vehicle and associated assembly methods are disclosed in EP 1 632 414 A1 and WO 2006/027196 A1.
  • the coupling head housing is generally funnel-shaped and has a connection area, for example an end piece, on the side opposite the end plate, which is suitable for receiving a coupling rod.
  • the coupling rod is in turn arranged on the vehicle such that it can be displaced or pivoted vertically and laterally, so that the funnel-shaped configuration can accommodate the counterpart with corresponding tolerances.
  • the coupling head housing has a first connection area for fixing the end plate and a second connection area, in particular a coupling element for receiving the coupling rod.
  • the actual coupling element for producing a fixed and detachable connection with another coupling element of a counter-coupling is arranged inside the coupling head housing. This coupling element is firmly connected to the clutch housing.
  • the coupling head housing is a cast part on which the coupling elements or coupling mechanism are arranged.
  • coupling heads with a modular design have various advantages.
  • the modular design is achieved in that the end plate is detachably connected to the coupling head housing, so that the properties of the coupling head and its manufacturing process can be optimized overall. Different coupling head housings can be mounted on different end plates and one overall design and a holistic production of the complete coupling head are no longer necessary.
  • the face plate can also be removed for maintenance or repair work inside the coupler head housing, giving service personnel easier access to the uncoupler cylinders and other parts of the coupler lock.
  • a coupling head with a coupling head housing which is constructed and designed as a forged component, is already known from publication DE102013218156 A1 in order to reduce the overall size and costs.
  • This has finger-like at least two, preferably at least four, separate contact surfaces, which can be releasably connected to the end plate via bolt connections.
  • defined and, above all, locally limited force application areas are specified, which enable a locally limited force application into the coupling head housing.
  • the object of the invention is therefore to design a clutch arrangement in such a way that, in addition to a large number of variants, it enables simple assembly and maintenance, is structurally simple and compact, and is cost-effective.
  • a coupling component for a coupling for mechanically coupling rail-bound vehicles, which combines the function of the coupling head housing and coupling rod in an integral component design, with the coupling head housing being characterized by an open design in some areas.
  • a coupling component is provided with a longitudinally extending, one-piece main body, comprising a first axial end area, a second axial end area and a shank area formed between the end areas, wherein the first axial end area is designed to provide a receiving area for receiving coupling elements and at least form a terminal portion for attaching a face plate.
  • the first axial end area is formed by a fork structure, comprising a fork base and at least two fork parts spaced apart from each other and extending on both sides of the longitudinal axis technological end form the at least one connection area for attaching a face plate.
  • the receiving area for the coupling elements is defined or delimited by the at least two fork parts, in particular their inner contour in the width direction and longitudinal direction of the base body. Viewed in the circumferential direction around the longitudinal axis, the receiving area is not completely surrounded by the one-piece clutch component but only laterally when viewed in the installed position.
  • Fork base in the context of the invention is understood in particular as meaning the area in which the fork parts arranged on both sides of the longitudinal axis are brought together or connected.
  • a shank area is understood to mean, in particular, an area in the axial direction between the first and second axial end area characterized by an extension in this direction, i.e. along the longitudinal axis, which is designed and suitable to perform or to at least perform the function of the coupling rod when used in coupling devices take over.
  • at least a partial area of the shaft area forms the coupling rod.
  • the solution according to the invention offers the advantage of providing a relatively simple and relatively minimalistic component for the main functions of the coupling head, in particular the coupling head housing and the coupling rod.
  • the fork parts integrally connected to the shank area assume the function of the coupling head housing, namely providing the connection areas for the end plate and the receiving area for the coupling elements.
  • a coupling element within the meaning of the invention is understood in particular to mean the coupling mechanism required to implement the mechanical connection, in particular the coupling closure. This is required for the mechanical connection.
  • the structure of a dome closure as a twist lock with a coupling eyelet and a frog, the frog being rotatable about a main axis at least between a position ready for coupling and a coupled position, is known in principle.
  • the frog has a mouth for receiving a corresponding second end of a coupling eyelet of an opposite coupling head.
  • the coupling head has a profiling of a coupling projection, in particular a cone, and a coupling opening, in particular in the form of a funnel, on the face side.
  • the one-piece base body is designed as a forged component.
  • the basic idea is to design a coupling head housing and the coupling rod connected to it more simply as a single component, so that this is easier to assemble on the one hand, but is also easier to manufacture on the other.
  • This is achieved in that the sub-area that assumes the function of the coupling head housing is constructed differently in contrast to the prior art.
  • this has at least two connection areas that are separated from one another in the manner of a fork and that can be releasably connected to the end plate by means of corresponding fastening devices.
  • defined and, above all, locally limited force application areas are specified, which enable a locally limited force application into the integral design of the fork structure that assumes the function of the coupling head housing and the shaft region that assumes the function of the subsequent coupling rod.
  • the coupling component is a one-piece forged component, the lines of force within it are homogeneous and can thus be optimally transmitted via the coupling head housing or fork structure and the subsequent shaft area.
  • the production time of a forged component is shorter. This is due to the fact that complex quality assurance processes such as X-rays, blowhole testing or the like are no longer necessary.
  • the post-processing processes are shorter, especially in the areas in which further elements are coupled.
  • An even shorter production time is achieved in that, in particular for the connection to the end plate, the free end regions of the fork structure do not rest over the entire surface, but rather a partial surface or, depending on the design of the fork structure and depending on the number of fork parts, a punctiform, finger-like contact, namely in particular on defined local areas.
  • the coupling elements or coupling mechanism can be arranged within the receiving area formed by the fork structure in such a way that their forces are diverted directly into the shaft area adjoining them, the load paths and directions in the clutch assembly separately in such a clutch component.
  • the fork structure that assumes the function of the coupling head housing can be dimensioned more simply. Because of this dimensioning, however, there is also the advantage that the overall length of the coupling component, which takes over the function of the coupling head housing and the coupling rod, together with the front plate, is considerably shorter compared to the prior art.
