Definitions

  • the invention relates to an arrangement for positioning a wheel of a rail vehicle.
  • the wheel On a rail vehicle, the wheel is often part of a wheelset.
  • the wheel set generally consists of a wheel set shaft and two running wheels. The wheels are attached to the axle and are carried by the axle.
  • the wheelset transfers the vehicle's weight and dynamic loads to the rails, guides the vehicle on the track and transmits vehicle propulsion and braking forces to the rails.
  • the wheel set is often part of a bogie, with the wheel set being mounted in a frame that can be rotated relative to the car body.
  • Vehicles with bogies can negotiate narrower curves than vehicles with axles rigidly attached to the car body, because the frame can rotate relative to the car body and the wheels can therefore touch the rail at a smaller angle.
  • Bogies also improve running smoothness, as they transmit fewer vertical and lateral shocks to the car body.
  • the wheels are held in their position in the frame under the rail vehicle by a so-called swing arm.
  • the swing arm is on one first end rotatably mounted with a bogie.
  • the rocker is connected to the axle.
  • FIG 4 shows such a rocker SCHW with wheelset shaft RSW and wheel LFR according to the prior art on a rail vehicle detail, see US2019/009798 .
  • the rocker SCHW is rotatably mounted at a first end SCHWE1 attached to a frame RAH of the bogie.
  • the rocker SCHW is connected to the wheelset shaft RSW in order to hold it in position.
  • the swing arm SCHW is connected to the frame RAH with additional springs in the vertical direction (not shown here). If a wheelset with large wheels is attached or positioned using rockers, problems arise when removing the wheelset during service or maintenance work. If the swing arm is detached from the bogie, the swing arm drops abruptly due to its high dead weight until it rests on the ground.
  • the invention relates to an arrangement for positioning a wheel of a rail vehicle with a wheel, with a rocker and with a frame of a bogie of the rail vehicle.
  • the wheel is carried by a wheel shaft.
  • the addressed wheel is either a non-driven wheel, which is also referred to as a running wheel, or alternatively an actively driven wheel.
  • the rocker has a first end which is pivotally connected to the frame of the bogie.
  • the swingarm has a second end connected to the wheel shaft.
  • the rocker has a fixed but detachable connection between the first end and the second end, which enables the rocker to be mechanically divided into two.
  • the wheel is part of a wheel set, the wheel set having a wheel set axle that carries two wheels or running wheels of the rail vehicle.
  • the fixed but detachable connection is designed as a screw connection or as a bolt connection.
  • the fixed but detachable connection has two flange plates, which are part of the screw connection or the bolt connection.
  • the rocker is designed to be approximately rotationally symmetrical in the area of its fixed but detachable connection, namely in relation to the axis of the wheelset. This prevents a swing arm part from tipping over during disassembly.
  • the fixed but detachable connection is preferably arranged almost in the center of the longitudinal rocker.
  • the present invention enables wheels or wheel sets of a rail vehicle to be dismantled or serviced more easily.
  • the present invention saves production and maintenance costs.
  • the present invention reduces or avoids contamination and corrosion on the swing arm bearing due to simplified maintenance work.
  • FIG 1 shows an embodiment of the arrangement according to the invention for positioning running wheels LFR of a wheelset of a rail vehicle not shown in detail here.
  • a wheelset axle RSW carries two running wheels LFR of the rail vehicle.
  • a rocker SCHW has a first end SCHWE1, which is rotatably connected to the frame RAH of a rail vehicle bogie.
  • the rocker SCHW has a second end SCHWE2, which is connected to the axle RSW.
  • the rocker SCHW has a fixed but detachable connection VERB, which allows mechanical division of the rocker SCHW into two parts SCHWT1, SCHWT2.
  • the fixed but detachable connection VERB is preferably designed as a screw connection, with two flange plates, for example, being part of the screw connection via which the screw connection takes place.
  • FIG 1 two springs FED1, FED2 can also be seen, via which resilient support is realized in the vertical direction.
  • FIG 2 shows with reference to FIG 1 the part SCHWT1 of the rocker SCHW remaining on the wheelset with a separate connection VERB.
  • This part SCHWT1 of the rocker SCHW is preferably designed to be approximately rotationally symmetrical, preferably to the axis of the wheelset. This makes it easier to handle the wheel set that has been removed. Tilting of a swing arm part is avoided by the almost central split of the swing arm shown here.
  • FIG 3 shows with reference to FIG 1 the part SCHWT2 of the rocker SCHW remaining on the bogie with a separate connection VERB.
  • connection VERB is preferably selected in such a way that the part SCHWT2, which is difficult to assemble, remains on the bogie frame RAH.
