Definitions

  • Coupling arrangement in particular for a rail vehicle
  • the present invention relates to a coupling arrangement, in particular for a rail vehicle, according to the preamble of claim 1.
  • FIG. 7 A previously known in practice generic coupling arrangement is shown schematically in Figure 7.
  • a coupling rod 1 which extends along a longitudinal axis 2 and carries a coupling head 3 in the region of a first axial end, held in the bearing block 4 on the carriage body of a rail vehicle, not shown.
  • a support structure 7 which supports the coupling rod 1 by means of a support spring 16 from below. By its bias holding the support spring 16, the coupling rod 1 in the appropriate height, by its spring reserve allows the necessary up and down movements.
  • an opening for the bearing block 4 is provided in a base plate 9 which is fixed to the car body.
  • This opening is sufficiently large that the coupling rod 1 in the case of an overload in the longitudinal direction, that is in the direction of the longitudinal axis 2, fits through the opening therethrough.
  • an overload case occurs when an impact of the rail vehicle on an obstacle and is also referred to as a crash case.
  • an energy absorbing element 8 is provided, which deforms in the longitudinal direction when the overload occurs and thereby absorbs at least part of the excess force in the direction of the longitudinal axis 2.
  • the coupling rod 1 at least partially slip through the opening of the base plate 9 and the connection to the support structure 7 and the support spring 16 is separated, for example by shearing.
  • a disadvantage of the embodiment shown is that the support structure 7 occupies a comparatively large space below the coupling rod 1 and requires an additional bearing block 17, with which it is pivotally connected to the base plate 9 and is supported by this.
  • the present invention has for its object to improve the illustrated generic coupling arrangement such that the support structure occupies a smaller space outside the coupling rod, advantageously has a lower weight and in particular the power flow in the event of an overload as little as possible changes and advantageously the compatibility guaranteed energy consumption.
  • a clutch assembly according to the invention which is particularly suitable for a rail vehicle, but is also applicable to other vehicles, the clutch assembly, for example, the coupling of two rail vehicle parts with corresponding clutch assemblies or cooperating clutch assemblies is used, has a coupling rod, which extends along a longitudinal axis extends and carries a coupling head in the region of a first axial end.
  • a bearing block on which the coupling rod is pivotally connected to a arranged opposite to the first axial end second axial end about a vertical axis.
  • Hinged connected about a vertical axis means in particular that the connection produces a mechanically at least substantially rigid coupling in the direction of the longitudinal axis between the coupling rod and the bearing block, optionally apart from possible in particular elastic deflections, but at the same time a sufficiently large angular deflection of the coupling rod relative to the bearing block and in particular a subsequent energy consumption element and / or against the bearing block enclosing base plate allows so that the coupling rod when driving through curves can swivel accordingly sideways.
  • a bearing between the bearing block and the coupling rod is provided, which is adapted to allow at least a limited movement between the coupling rod and the bearing block in the vertical direction.
  • the movement is achieved for example by an elastic bearing.
  • the bearing block is already movable in the vertical direction.
  • a support structure is provided, which elastically supports the coupling rod against the movement in the vertical direction, to ensure the above-mentioned holding the coupling rod at the correct height.
  • the support structure is positioned in the vertical direction at least predominantly at the height of the bearing block and / or the coupling rod substantially coaxially to the longitudinal axis. This means that the majority of the support structure protrudes in the vertical direction in only a small amount beyond the coupling rod, for example by a maximum of half or one third of the diameter of the coupling rod. Even an even closer nestling of the support structure to the coupling rod is possible, so that the support structure protrudes, for example, only a quarter of the diameter or less over the coupling rod.
  • the above statements relate at least to a lateral plan view in the horizontal direction on the coupling rod.
  • the coupling rod is positioned at least substantially coaxial with the longitudinal axis, which means that the central axis or longitudinal axis of the support structure is arranged close to the longitudinal axis of the coupling rod, in particular runs within the outer periphery of the coupling rod, for example with a maximum distance of half Radius of the coupling rod or less, largely no additional space outside the coupling rod is blocked by the support structure.
  • the support structure is therefore largely not arranged eccentrically to the coupling rod.
  • the coupling assembly is free from a radially outwardly of the coupling rod outwardly of the coupling rod supported supporting structure, which in the present case by the term worn any suspension of the corresponding component, here the support structure is to be understood, in which the weight forces of the component and possibly on the Component-acting operating forces are absorbed by the supporting element, for example by the bearing block or a base plate, which is fixed for example to the car body.
  • the support structure extends above and below the coupling rod and / or above and below the bearing, that is, both in a plane above the coupling rod or the bearing and a plane below the coupling rod or the bearing. It is understood that the support structure is usually not only provided with planar components, but extends advantageously curved around the coupling rod. According to an advantageous embodiment of the invention, the support structure is pivotally connected to the bearing block and supported by this. Reference is made to the above meaning of the word carrying. In particular, the support structure is supported exclusively by the bearing block.
  • the support structure is pivotally connected to the same vertical axis as the coupling rod to the bearing block.
  • the bearing block is axially connected to a deformable energy absorbing element, which in particular has a tubular shape.
  • a base plate enclosing the bearing block and / or the energy-dissipating element is provided, which is set up to connect the coupling arrangement to a body of the rail vehicle or to another vehicle component.
  • the support structure is articulated, in particular articulated connected to the said vertical axis on the base plate and is supported by this, in particular exclusively. Also in this regard, reference is made to the above definition of wearing.
  • the support structure above and below the coupling rod and / or the bearing is pivotally connected to the bearing block and / or the base plate and is supported by the corresponding component.
  • the support structure has a carrier surrounding the coupling rod over its circumference and at least two lateral guides connected to the carrier, the lateral guides enclosing the coupling rod in the horizontal direction between them.
  • the lateral guides can be beneficial over a running below the coupling rod, the coupling rod from the bottom supporting crossbar be connected to each other.
  • the lateral guides are rigidly connected to the carrier and the crossbar is connected at least in the vertical direction elastically to the lateral guides.
  • pillars standing upright on the cross-beam, which are enclosed by the lateral guides over their circumference and are supported in the lateral guides by means of a spring element.
  • the bearing can be designed for example as a spherical bearing.
  • the bearing is designed as an elastic bearing, in particular as a rubber-metal bearing.
  • the two lateral guides also contribute to the high bending resistance torque. However, at least they contribute to a more favorable introduction of force into the structure by positively influencing the bending resistance moment in the transition between guides and the support of the support structure. If the lateral guides have an outer, round, in particular cylindrical, surface and more or less closely conform to the coupling rod, a comparatively high rigidity is also achieved in the transverse direction. In particular, the transverse stiffness results from the overall curved shape of the support of the support structure, the guides additionally having the said influence on the rigidity.
  • connection of the support structure to the bearing block which accounts in particular additional connection points on the base plate, such a small diameter can be achieved that in the event of a crash, the support structure is pushed together with the bearing block and the coupling rod through the opening of the base plate. Only the side guides, if they do not fit through the opening due to their size, must be separated from the support structure, which can be achieved for example by shearing or a suitable plug-in mechanism. With a connection of the support structure to the base plate, in particular above and below the bearing block, so that the support structure surrounds the bearing block, the necessary space can still be kept low and a particularly high rigidity can be achieved.
  • FIG. 6 shows a lateral plan view of the embodiment according to FIG. 5.
  • the support structure 7 adjoins the coupling rod 1 particularly tightly from the outside. Furthermore, the components of the support structure 7 are positioned substantially coaxially with the coupling rod 1 or its longitudinal axis 2.
  • the coupling rod 1 is movably connected to the bearing block 4 via the spherical elastic bearing 6.
  • the mobility is achieved by the articulated connection about the vertical axis 5 and further by the elasticity of the bearing 6.
  • the bearing block 4 has a rohrformige structure with a subsequent yoke and the coupling rod 1 has in the region of the second axial end a bearing ring into which the bearing 6 is introduced, further comprising a pin 18 is provided by the yoke and the bearing 6 is guided to form the desired rotational mobility about the vertical axis 5.
  • the bearing block 4 is connected to an energy absorbing element 8 which is positioned coaxially with the coupling rod 1.
  • the bearing block 4 is further enclosed by the base plate 9 on its outer periphery, such that in a crash, the bearing block 4 and optionally the coupling rod 1 in the direction of the energy dissipation element 8 can be pushed through the base plate 9.
  • a support 10 which has a closed about the longitudinal axis 2 basic shape with an axially adjacent yoke 19th has, in the yoke of the bearing block
  • the carrier 10 has two in the region of the yoke 19 opposite axial end connected lateral guides 1 1, 12, which are provided with hollow cylinders 20, 21 and over which the coupling rod 1 from below supporting crossbar 13 are interconnected.
  • the carrier 10 thus does not fit through the opening of the base plate 9, so that in a crash, the coupling tube 1 of the support structure 7, here the cross-beam 13 is separated. Accordingly, it is not necessary to separate the lateral guides 1 1, 12 or the hollow cylinder 20, 21 from the carrier 10.
