Definitions

  • the invention relates to a running gear for a rail vehicle, having at least one running gear frame and at least one first pair of wheels mounted on the inside.
  • sensors of train protection systems such as antennas or release levers for travel locks must be attached as far forward as possible in the direction of travel of a rail vehicle and in the vertical direction close to the top edge of the rail.
  • train protection sensors can be arranged on a longitudinal beam of a bogie frame.
  • this is often difficult to do because, according to the principle of internal mounting, the solebar of the bogie frame runs within pairs of wheels and external wheels prevent train protection sensors from being directly connected to a front side of the bogie.
  • pantographs and other components whose design must take into account vertical movements relative to the upper edge of the rail.
  • Siemens SF7000 bogie with internal bearings is known from the prior art.
  • U.S. 2,636,451 A a chassis for a rail vehicle and a damping device between the chassis and a car body.
  • a housing of an anti-skid device is rotatably mounted on one end of a wheelset shaft and secured against twisting by means of an arm.
  • the arm is in turn elastically connected to a chassis frame.
  • the invention is therefore based on the object of specifying a running gear that is improved over the prior art.
  • This measure has the advantage that interface components such as pantographs or train protection sensors etc. can be arranged in the vicinity of a railway infrastructure and thus interaction of these interface components with train protection devices provided in the outer areas of tracks, for example in a track body, is facilitated.
  • At least one component designed as a current collector, as a de-icing device, as a monitoring device for a power rail or as a train protection sensor is arranged on the adapter rocker.
  • a favorable solution results when the adapter rocker is connected to the chassis frame with a longitudinal rigidity which allows relative movements between the chassis frame and at least the first pair of wheels.
  • At least one component arranged on the adapter rocker is designed to be vertically adjustable via a fastening means. This measure results in favorable flexibility with regard to adapting the component to different designs and design properties of running gear as well as to properties of a corresponding railway infrastructure (e.g. when the component is designed as a pantograph).
  • At least one component is arranged on the adapter rocker in such a way that the functions of the at least one component are compatible with the relative movements between the adapter rocker and the first wheel.
  • This measure achieves the advantage of an approximately constant relative distance between the component and a top edge of the rail. This is particularly important if the component is used as an interface component to a railway infrastructure is implemented.
  • Functions of at least one component are compatible with the functions of other components of the chassis. These measures prevent components of the running gear from interfering with one another, for example a magnetic track brake affecting the signal transmission of a train protection antenna through an electromagnetic field.
  • the invention is explained in more detail below using exemplary embodiments.
  • a in 1 illustrated floor plan shows a first exemplary variant of a chassis according to the invention for a rail vehicle.
  • the running gear comprises a running gear frame 1 with a first pair of wheels 14 mounted on the inside and a second pair of wheels 15 mounted on the inside, which are designed as wheelsets.
  • FIG. 1 shows a longitudinal section through the chassis frame 1, the longitudinal section having a first wheel 2 and a second wheel 3.
  • the running gear comprises a first wheelset shaft 4 and a second wheelset shaft 5.
  • the first wheelset shaft 4 is rotatably connected to the running gear frame 1 via a first wheelset bearing unit 6 and the second wheelset shaft 5 is connected via a second wheelset bearing unit 7.
  • the first wheel set bearing unit 6 and the second wheel set bearing unit 7 each have a wheel set bearing with a wheel set bearing housing.
  • An adapter rocker 8 is on an in 1 The area shown on the right is arranged on an outside of the chassis.
  • the longitudinal rigidity of the rotary joint 9 is low and is therefore advantageous because it allows relative movements between the first wheel 2 and the first wheelset axle 4 in the direction of a longitudinal axis 13 .
  • a swing arm bearing unit 10 is arranged at the end of the adapter swing arm 8 shown on the right.
  • the rocker bearing unit 10 includes a rocker bearing that is designed as a roller bearing and rotatably connects a stub of the first wheel 2 to the rocker bearing unit 10 .
  • a train protection sensor ie arranged an interface component to a railway infrastructure.
  • This is designed as a vertically downward-pointing release lever 11 of a travel lock for a train protection system.
  • the side surface has fastening means (not shown) with a toothed plate, via which the release lever 11 can be adjusted in its vertical position. Furthermore, the fastening devices have elastic elements that mechanically decouple the release lever 11 from the adapter rocker arm 8 .
  • the arrangement of the release lever 11 on the side face of the rocker bearing unit 10 is advantageous since at this point of the adapter rocker 8 the relative movements between the first wheel 2 and the adapter rocker 8 or the release lever 11 are small.
  • the relative distance between the release lever 11 and a rail, not shown, on which the first wheel 2 and the second wheel 3 roll, or the track remains approximately constant.
  • a route stop of the train protection system arranged in the track body can be reached with great certainty by the release lever 11 .
  • FIG. 2 shows the in 1 illustrated first variant of a chassis according to the invention as a side view.
  • the floor plan shown shows a second exemplary variant of a chassis according to the invention with internal storage for a rail vehicle.
  • in 1 has an in 3 shown adapter rocker 8 on a bottom designed as a train protection antenna 12 train protection sensor, ie an interface component to a railway infrastructure.
  • the shape of the adapter rocker 8 and the arrangement of the train protection antenna 12 on it are flexible and therefore advantageous. Interactions with other components of the running gear (for example magnetic rail brakes, not shown) can be avoided in this way.
  • FIG 4 shows a side elevation of the in 3 illustrated, second variant of a chassis according to the invention.
  • Figure 2 , 3 and 4 train protection sensors arranged on an adapter rocker 8 are favorable solutions. According to the invention, however, it is also possible to arrange a current collector, a de-icing device, for example a de-icing brush or a liquid de-icing system, a monitoring device for a conductor rail or a brake, etc. on the adapter rocker 8 .
  • a de-icing device for example a de-icing brush or a liquid de-icing system
