Abstract

At least one of the coupling parts (2,5) thrusts lengthways against its car via a buffer device (10), possibly both parts of the coupling being thus protected (10). The first part coupling element (2) comprises a two-arm fork, its arms (2a,2b) bored (3) to register via a bolt (4) led through them. The second car coupling part consists of a lashing arm (5) itself bored (6) to admit the bolt (4) when the arm (5a) engages the fork. A ball joint (7) between bolt (4) and eyelet (5a) is an elastomer and the buffer (10) is of the destructive type offering permanent deformation, notably by two colliding tubes.

Description

  • The invention relates to a coupling device for on a common Chassis-supported ends of two articulated, neighboring vehicle units of a rail-bound articulated vehicle according to the preamble of claim 1.
  • Coupling devices of this type are known, for example, from DE-AS 16 05 188, DE 196 38 763 A1, DE 41 21 080 A1 or EP 0 771 710 A2 known.
  • From DE-AS 16 05 188 a coupling device is known, consisting of one attached to one vehicle unit, an upper and a lower one Fork piece having fork head, one on the other vehicle unit fastened, inserted between the two fork pieces of the fork head Connection tab and one aligned openings in the Fork pieces of the fork head and vertically passing through in the connecting bracket Coupling bolt, with the clevis below the lower fork piece forms a concentric to the coupling pin bearing ring, which in one the rotating bogie arranged on the common bogie. In the Connecting tab is a spherical bearing, so that a mutual vertical and gimbal rotation of both vehicle units against each other is possible.
  • From DE 41 21 080 A1 and DE 196 38 763 A1 Coupling devices of a similar design are known, in which the pin axis of the spherical Joint, however, rotated by 90 ° arranged horizontally in the vehicle transverse direction is. The coupling device of DE 41 21 080 A1 consists of a a vehicle unit attached, two side fork cheeks Clevis, one attached to the other vehicle unit, between the two connecting links and one fork Coupling bolt with spherical bearing arranged in the connecting bracket. The The clevis and the connecting strap are on the assigned to them Vehicle units rigidly attached in the longitudinal direction, creating the vertical Axis of rotation of the rotating pan with respect to the central perpendicular of the spherical bearing align, as the top of the rotary pan is also rigid with the clevis connected is. The spherical bearing is firmly attached to the coupling bolt Connection tab arranged. The horizontal rotations between the car bodies are picked up by the rotating pan, the vertical ones and gimbal movements from the spherical joint.
  • EP 0 612 646 A2 shows a coupling device which is a roller bearing has, which of a protruding beyond the end of a vehicle unit Support bracket is held and with one over the end of another Support bracket protruding above a hemispherically designed vehicle unit Elastomeric joint interacts and horizontal and vertical as well allows gimbal deflection movements of the vehicle units against each other.
  • All coupling devices have in common that the two to be coupled Vehicle units each assigned coupling elements of the coupling device are rigidly attached to the associated vehicle unit in the longitudinal direction.
  • From DE 19 47 819 A1, DE 15 30 223 A1 or DE 32 28 941 A1 devices for receiving oversized shocks are known, which at Middle buffer couplings for rail vehicles are used, with which two Vehicle units that can be moved independently of one another are required for formation or disconnect a vehicle group automatically or are uncoupled. A downstream of the coupling head, usually in the Coupling rod integrated overrun protection takes after exhausting the Absorption capacity of the elastic energy dissipation elements still occurring Impact energy, e.g. B. after a rear-end collision. Such overburst safeguards the aforementioned prior art are considered to be destructive Anti-surge devices are formed by a pairing of inner pressure pipe and outer Deformation tube or outer pressure tube and inner deformation tube formed is, the force of a predetermined size with permanent deformation of the deformation tube can be telescoped.
  • The invention has for its object vehicle units by a Coupling device of the type mentioned hinged together connected to a vehicle association and together on a chassis are supported against impermissible compressive forces in the body and Base structure, caused by longitudinal knocks, and therefore better protect from damage.
  • According to the invention, this object is achieved by a coupling device solved the features of claim 1. Advantageous embodiments of the Subject of the invention are specified in subclaims 2 to 11.
  • The invention is based on an embodiment with reference to the Drawing explained in more detail. Show it:
  • Fig. 1 is a side view of the coupling device with fork arm, link arm, spherical joint and overbolt protection in partial section and
  • Fig. 2 is a plan view of the coupling member fork arm with an overburst protection in plan view in partial section on an enlarged scale.
  • The coupling device 1 has a first coupling element 2 assigned to the first articulated vehicle, which is designed as a two-armed fork, the fork arms 2 a and 2 b of which have mutually opposite, aligned openings 3 and a bolt 4 penetrating them. The second coupling element 5 assigned to the second articulated vehicle is designed as a link arm 5 a with a link eye 6 .
  • The tab arm 5 a engages in the fork formed by the fork arms 2 a, the tab eye 6 being penetrated by the bolt 4 . A spherical joint 7 is arranged between the tab eye 6 and the bolt 4 . The joint 7 is preferably designed as an elastomer joint. In this case, an elastomer layer 9 is introduced between the spherical joint body 7 a and the outer ring 8 encompassing it at least in some areas.
  • By means of the arrangement described above, both articulated vehicles are connected to one another without play in an articulated coupling. The coupling device 1 and the joint 7 allow horizontal, vertical and also cardanic movements and torsional movements of the articulated vehicles against one another within the scope of the intended angular rotations. The tensile and compressive forces acting on the articulated vehicles and the coupling device 1 during driving operation are absorbed elastically / reversibly by the impacted coupling element 2 or 5 through the joint 7 or through the elastomer layer 9 and passed on to the coupling element 5 or 2 of the adjacent vehicle unit.
  • At least one coupling element 2 , 5 of the articulated coupling is supported against the respectively assigned vehicle unit in the longitudinal direction of the vehicle by means of an overrun protection device 10 . In the exemplary embodiment, both coupling elements 2 , 5 of the articulated coupling are supported against their respectively assigned vehicle unit in the longitudinal direction of the vehicle via an interposed overturn protection 10 .
  • As a shock absorber 10 types are suitable, may be where individual with permanent deformation component shock energy added (destructive working excessive impact fuses) or designs, can be where added impact energy through resistive displacing sufficiently viscous fluids into chambers by displacement bodies (cylinders) and non-destructively removed ( regenerative push-over protection, e.g. an elastomer cartridge of a known type). After their response, the initial state and thus its further use can be economically restored in the case of the aforementioned regenerative overrun protection.
  • The impact protection 10 in the exemplary embodiment is designed to work destructively and is formed by a pairing of inner pressure tube 11 and outer deformation tube 12 , which can be telescopically pushed into one another under the action of a predetermined size while permanently deforming the deformation tube 12 . Arrangements, not shown, with an outer pressure tube and an inner deformation tube or combinations of pressure and deformation tubes (e.g. DE 15 30 223 A1 or DE 19 12 049 A1) would have the same effect.
  • As already mentioned, the forces occurring in normal driving operation are absorbed and damped elastically / reversibly by the joint 7 or by the elastomer layer 9 . After exceeding the forces occurring in normal driving and after exceeding the response force of the overrunning protection 10 (e.g. in the event of a strong impact in rear-end collisions), the overrunning protection 10 responds and, in the exemplary embodiment, reduces impact energy by plastically deforming the deformation tube 12 and thus protects the articulated coupling and the vehicle units, especially their bases, are better protected from damage.
  • The bolt 4 penetrating the fork arms 2 a, 2 b and the openings 3 of the fork arms 2 a, 2 b are arranged in vertical alignment. This vertical arrangement allows larger horizontal turning angles of the vehicle units against each other.
  • Advantageously, the overturn protection devices 10 and the coupling elements 2 , 5 connected to them are designed to be longitudinally displaceable in the longitudinal direction by means of a guide 13 , ie they are also supported vertically and horizontally. This type of construction also allows vertical and horizontal forces to be absorbed in the area of the overrun protection device 10 , which makes it more difficult for a vehicle unit to dodge or climb over the connected, adjacent vehicle unit.
  • The common support of the two ends of the adjacent, articulated vehicle units can be carried out via a common bogie or a single-axle chassis (both types with wheelsets or idler wheels possible), the coupling device for both central, i.e. symmetrical support with respect to the vertical central transverse planes by the chassis Ends of adjacent vehicle units on the chassis (so-called Jakobs arrangement) as well as for articulated vehicles with saddled vehicle ends are suitable. In the latter, the common undercarriage is arranged under the end of a first vehicle unit, whereas the end of the adjacent vehicle unit - based on the design of a road semitrailer with tractor and semi-trailer - is saddled onto the vehicle end of the first vehicle unit.
