Definitions

  • the invention relates to a length-adjustable coupling rod for central buffer couplings of rail vehicles.
  • the coupling head protrudes from the front of the vehicle profile.
  • center buffer clutches the coupling head and coupling rod of which can be moved behind the front vehicle profile when not in use, are particularly suitable for rail vehicles that do not run on their own routes, e.g. B. tram vehicles in order to avoid endangering other road users by the coupling head projecting from the front of the rail vehicle.
  • the energy dissipation elements arranged in the coupling rod or on the support are no longer ready for operation. In the event of an impact, the impact energy must be absorbed by other assemblies and elements.
  • Length-adjustable couplings are also known, which can be pushed under the vehicle body in the uncoupled state.
  • a coupling rod with coupling head can be pushed in and out relative to the car body and can be locked in both end positions.
  • the coupling rod is provided at the free end with a stop bolt passed through it and displaceable in a sleeve which has two mutually opposite longitudinal slots for guiding the stop bolt, which are expanded at both ends in the manner of a bayonet lock.
  • the coupling rod In the known push-in couplings, the coupling rod usually slides in a sleeve that lies between the articulation point on the vehicle and the end of the car. The entire length of the coupling rod is also in the retracted position between the end of the car and the point of articulation, so that the point of articulation is relatively far from the end of the vehicle. Since a large pivoting range of the coupling rod must be provided when driving through tight curves, a large space at the end of the carriage is lost for the insertion of other assemblies when the coupling rod is longer. In the case of low-floor vehicles in particular, the installation space is not available for such an adjustment device.
  • the invention is therefore based on the object of providing a length-adjustable coupling rod which requires little installation depth and also has ready-to-use energy consumption elements installed in the coupling rod in the inserted position.
  • the coupling rod shown in FIGS. 1 to 3 has a carrier body 1 with front support 2 and rear support 3.
  • a length-adjustable section is arranged between the supports 2, 3.
  • the length-adjustable section is formed by two scissors 4 and 5 arranged opposite one another.
  • the front scissors 4 are formed by a left scissor element 4a and a right scissor element 4b, the scissor elements 4a and 4b being articulated in a plane perpendicular to the central longitudinal axis of the coupling rod at the same height on the front support 2 by means of joints 6.
  • the rear scissors 5 are formed by a left scissor element 5a and a right scissor element 5b, the scissor elements 5a and 5b being articulated in a plane perpendicular to the central longitudinal axis of the coupling rod at the same height on the rear support 3 by means of joints 7.
  • the scissor elements 4a, 4b of the front scissors 4 are assigned to the scissor elements 5a, 5b of the rear scissors 5 in a largely mirror-symmetrical manner, the scissor elements 4a and 5a of the scissors 4 and 5 and the scissor elements 4b and 5b of the scissors 4 and 5b being arranged opposite one another 5 are connected to each other in their front area by means of a joint 8.
  • the hinge axes of the joints 6, 7 and 8 are aligned vertically, so that the pivoting plane of the scissors 4 and 5 is aligned horizontally and parallel to the level of the underframe of the rail vehicle after the coupling rod has been attached to a rail vehicle.
  • At least one locking device 9 is assigned to the scissor elements 4a, 4b, 5a, 5b.
  • the locking device 9 prevents the scissors 4, 5 from spreading under tensile load.
  • the joints 8 connecting the opposite scissor elements 4a and 5a on the one hand and 4b and 5b on the other hand are in the extended position (extended position) in addition to those due to their respective articulation on the front support 2, in the joint 6, and the rear support 3, in the joint 7 , Level formed in the direction of the central longitudinal axis of the coupling rod arranged offset.
  • the scissors 4, 5 are arranged in the extended position in an over-center position under pressure.
  • the scissor elements 4a, 4b of the front scissors are supported on contact surfaces 10 on the front support 2, thereby preventing the scissors 4 and the articulated scissors 5 from buckling.
  • the locking device 9 has a fixed locking claw 9a, which is arranged on a scissor element 4b of a pair of scissors 4, and a bolt 9b which can be displaced or pivoted against the force of a spring 11 and which is arranged on a scissor element 5a arranged on the other side of the central longitudinal plane of the coupling rod a pair of scissors 5 is arranged and can be locked in the locked position in the fixed locking claw 9a.
  • an actuating device 12 for pivoting the scissors 4, 5 is arranged on the coupling rod, said actuating means acting in an articulated manner on the rear scissors 5 via actuating levers 14 on the scissor elements 5a, 5b.
  • the actuating device 12 is designed as an actuating slide 12 'with a linear guide of the actuating slide 12' by means of a guide rod 13.
  • the actuating device 12 is operatively connected to a control device 15, which in turn actuates the locking device 9.
  • the control device 15 is designed as a control slide 15 ′ with a linear guide and is preferably driven by means of an electric drive 16.
  • Pneumatic or hydraulic drives are also suitable as drive 16, which are selected depending on the expediency and available energy source.
  • the actuating device 12 is timed and actuated after the control device 15, i. That is, there is an idle stroke of the control slide 15 ', which initially unlocks the locking device 9 and only then also moves it with the actuating slide 12' by contact.
  • the control device 15 is driven by a lifting spindle drive 17.
  • the scissor elements 4a, 4b, 5a, 5b are expediently formed from U-profiles.
  • a shock absorbing device 18, for. B. arranged a regenerative elastomer cartridge.
  • the front scissor elements 4a, 4b are each spring-loaded against spreading by means of tension springs 19 which act on the one hand on the joint 8 and on the other hand on the front support 2.
  • the lifting spindle 16 is driven by the drive 15.
  • the lifting spindle 16 drives the control slide 14 'and displaces it in the direction of the rear support 3.
  • the control slide 14' pivots the Bolt 9b against the force of the spring 11 and disengages it from the locking claw 9a.
  • the dimensions of the elements of the coupling rod are designed such that the coupling head is placed behind the front vehicle profile in the retracted position.
  • the breakthrough in the front cladding in the coupling area of the vehicle can then be covered by means of a suitable apron or a cladding part, insertable, pivoting or displaceable cladding parts, which are generally arranged stationary on the vehicle, are known.
  • shock absorbing device 18 and possibly further shock absorbing devices of the linkage on the undercarriage side remain fully integrated between the coupling head and the rear support 3 in the coupling rod.
  • the lifting spindle 17 is driven in opposite directions via the drive 16.
  • the lifting spindle drive 16 drives the control slide 14 'and displaces it in the direction of the front support 2. After an idle stroke, the control slide 14' comes to rest against the actuation slide 12 'on its way towards the front support 2 and moves it in the same direction .
  • the scissors 4 is pivoted as in the process of retracting the coupling rod.
  • the movable bolt 9b rotates against the force of the spring 11 behind the fixed locking claw 9a and secures the coupling rod against spreading of the scissors 4, 5 under tensile load.
