Definitions

  • Such a bogie is for example from the EP 0 918 676 B1 known.
  • the wheelset is mounted directly on the wheelset.
  • On the side facing away from the transmission elastic suspension is realized.
  • On the side facing the transmission a connection with a clutch is realized, which in turn is supported by means of elastic elements against the wheelset shaft.
  • a direct drive is known as the INTRA ICE, in which the wheelset drive concentrically surrounds the wheelset shaft and acts directly on the wheelset shaft.
  • a wheel hub drive with integrated planetary gear is known in which the drive is integrated directly into the wheel of the rail vehicle.
  • a bogie which has a chassis frame.
  • the chassis frame is spring mounted on bearings via a spring device.
  • wheel shafts are supported by wheels.
  • the wheels are connected via a hollow shaft, within which a wheelset drive is arranged.
  • the wheelset drive acts on the shafts. He is by means of a Radsatzantrieb proprietary associated further spring means within the Hollow shaft mounted sprung. Between the wheelset and the wheelset a clutch is arranged.
  • a bogie which has a chassis frame.
  • the chassis frame is spring mounted on bearings via a spring device.
  • a wheelset of a wheelset is stored in the bearings .
  • a wheelset drive acts on the wheelset shaft.
  • the wheelset is mounted by means of a wheel drive proprietary assigned further spring means resiliently on the bearings.
  • a bogie which has a chassis frame.
  • the chassis frame is spring mounted on bearings via a spring device.
  • a wheelset of a wheelset is stored in the bearings .
  • a wheelset drive concentrically surrounds the wheelset shaft. He acts on the wheelset.
  • the object of the present invention is to provide a bogie of the type mentioned in such a way that a bogie is created, the drive acts by means of a simple, reliable, virtually maintenance-free and easy to assemble construction on the wheelset, yet the unsprung masses are kept low.
  • the two-way clutch is designed as a double-toothed coupling.
  • the space required for the two-way clutch can be minimized.
  • the second spring means may be formed as a group of buffer elements made of permanently elastic material ("rubber buffer"). This embodiment is particularly inexpensive and low maintenance. Alternatively, the second spring means may be formed as a group of coil springs. By means of such spring devices can be realized in particular in a simple manner, a large spring travel. In addition to the suspension damping is preferably realized. It is possible that the second spring device itself already has a damping effect. Alternatively, independent damping elements may be present.
  • the wheel set drive acts on the wheelset shaft without the interposition of a transmission.
  • a transmission may be present.
  • the wheelset drive acts on the wheelset shaft via the gearbox.
  • the gear is arranged in this case between the wheelset drive and the two-way clutch.
  • the transmission can be designed as needed in the case of its presence. In practice, it has proved to be advantageous if the transmission is designed as a planetary gear.
  • the planetary gear having a rotatably fixed sun gear arranged on a rotor shaft of the wheel set drive.
  • the wheelset shaft is in this case preferably rotatably connected via the two-way clutch with a planet carrier of the planetary gear.
  • the wheel set drive is connected by means of traction converters to an electrical supply.
  • the traction converters are usually arranged on the roof of the car body of the rail vehicle. In some cases, they are located underfloor between the bogies of the rail vehicle. Due to the compact construction of the wheelset drive of the bogie of the present invention, it is possible that the corresponding traction converters are arranged on the bogie itself. This ensures that the traction converters become part of a compact, self-contained bogie with a simple interface to the car body.
  • the traction converters are arranged directly on the chassis frame. In this case, they are sprung only via the first spring device (so-called primary suspension). As a result, they are exposed to increased vibration and shock loads during operation. In order to keep such increased vibration and shock loads from the car body, usually mounted on the chassis frame via a third spring device sprung relative to the chassis frame car body support. This suspension is usually referred to in practice as secondary suspension. About the car body support the car body itself is connected to the bogie. In a preferred embodiment, the Traction converter arranged on an underside of the carriage body. This allows the bogie (including the arranged on the bogie converter) continue to be kept compact and self-sufficient. Even the simple interface to the car body can be maintained. The arrangement of the power converter on the car body support, however, the vibration and shock loads are reduced to the level (or lower), which they would be in a conventional arrangement - ie on the roof of the rail vehicle or underfloor between the bogies - exposed.
  • FIG. 1 Rolls a rail vehicle 1 with wheels 2 on rails 3.
  • the rail vehicle 1 is electrically driven. It takes from a catenary 4 by means of a pantograph 5 electrical power.
  • a supply via a third rail, arranged on the rail vehicle 1 energy storage or arranged on the rail vehicle 1 internal combustion engine is possible.
  • the rail vehicle 1 has a plurality of - generally two - bogies 6.
  • the design of the bogies 6 is the subject of the present invention. The following is in conjunction with the FIGS. 2 to 4 the design of one of the bogies 6 explained in more detail.
  • the other bogies 6 may also be formed.
  • FIGS. 2 to 4 has the bogie 6 a chassis frame 7.
  • the chassis frame 7 is resiliently mounted on bearings 7b via a first spring device 7a (primary suspension).
  • a wheelset shaft 8 of a wheelset is mounted in the bearings 7b .
  • a wheelset is, as is customary, from the wheelset 8 and the two at the two ends of the wheelset 8 with the wheelset 8 rotatably connected wheels 2.
  • the bearings 7b between the wheels 2 of the wheelset.
  • Most are mounted on the bogie 6 more sets of wheels, for example, two or in some cases, three wheelsets. However, the number of wheelsets per bogie 6 is of minor importance.
  • the wheelset shaft 8 is provided with a wheelset 9, the - see FIG. 4 -
  • the wheelset 8 concentrically surrounds.
  • the wheel set drive 9 has a rotor shaft 10 which is rotatably mounted in the wheel set drive 9 in drive bearings 11.
  • the rotor shaft 10 is according to the FIGS. 2 to 4 with an input shaft 12 of a transmission 13 rotatably connected.
  • An output shaft 14 of the transmission 13 acts via a two-way clutch 15 on the wheelset 8.
  • the transmission 13 could be omitted. In this case, the rotor shaft 10 would be connected directly to the two-plate clutch 15.
  • the wheelset drive 9 can be designed as such as needed. It can be designed, for example, as a - in particular higher-pole - synchronous machine with permanent-magnetic excitation and radial flow design. Alternatively, however, other designs are possible such as asynchronous machines, reluctance machines (with or without permanent magnetic Arousal) and others more.
  • the cooling of the wheel set 9 can be configured as required as water jacket cooling, as air cooling, as refinewindkühlung and so on.
  • the wheelset 9 is arranged relative to the axle 8 axially as well as radially movable. An angular movement, ie a tilting of the wheel set 9 relative to the wheelset shaft 8, is possible.
  • the wheel set drive 9 is spring-loaded for this purpose by means of a second spring device 16 on the bearings 7b.
  • the second spring device 16 may, for example, as shown in FIG. 4 be formed as a group of buffer elements 17, wherein the buffer elements 17 are made of permanently elastic material.
  • the permanently elastic material may be, for example, a metal-rubber mixture.
  • the second spring device 16 as shown in FIG. 5 be formed as a group of coil springs 18.
  • the gear 13 may be formed, for example, as a planetary gear.
  • the sun gear 19 is preferably hollow drilled and rotatably mounted on the rotor shaft 10.
  • the sun gear 19 corresponds to the input shaft 12.
  • the ring gear 21 is preferably non-rotatably mounted on the wheel set drive 9.
  • the planet gears 20 are arranged on a planet carrier 22.
  • the planet carrier 22 preferably corresponds to the output shaft 14.
  • the wheelset shaft 8 is in the case of this embodiment via the two-way clutch 15 rotatably connected to the planet carrier 22 of the planetary gear 13.
  • the two-way clutch 15 is able to compensate for both radial displacements and axial displacements and tilting of the wheel set drive 9 relative to a rotation axis 23 of the wheel set shaft 8.
  • the two-way clutch 15 is designed for this purpose as a double-toothed coupling. Double-toothed couplings are known to those skilled in the art and therefore need not be explained in detail.
  • the bogie 6 explained above is very compact.
  • the gear 13 requires only about 20% to about 35% of the total space available for driving the wheel set 8 space.
  • the wheelset drive 9 can therefore - compared with a direct drive, in which no gear is available - apply about 65% to about 80% of its torque.
  • a relatively high reduction can be achieved, for example, of about 3: 1.
  • the effective torque required in particular during startup can therefore be approximately 200% to approximately 250% of the torque that could be exerted on the wheelset shaft 8 by means of a direct drive requiring the same installation space as the wheel set drive 9 including the transmission 13.
  • the wheelset drive 9 of the bogie 6 according to the invention also requires, viewed in the direction of travel, only a relatively small installation space. It is therefore - compared to conventional bogies 6 - alternatively a shortening of the bogie 6 or an exploitation of the unused space for other purposes possible. In particular, it is as shown in FIG FIG. 6 possible to arrange in this space and thus in particular on the bogie 6 itself traction converter 25. By means of the traction converter 25 of the wheelset 9 is in operation at a switched on electrical supply, for example, the already mentioned overhead line. 4
  • a car body support 27 is mounted via a third spring device 26 (secondary suspension).
  • the car body support 27 is at am Rail vehicle 1 mounted bogie 6 fixed to a car body 28 (see FIG. 1 ) of the rail vehicle 1.
  • the car body support 27 can as shown in the FIG. 3 and 6 be designed for example as a crossbar.
  • the traction converters 25 are as shown in FIG FIG. 6 arranged on an underside 29 of the car body support 27.
  • the present invention has many advantages.
  • an integrated, compact concentric wheel set drive 9 can be realized with or without gear 13 in a simple manner.
  • the bogie 6 according to the invention allows with gear a high starting and braking torque. It is particularly suitable for rail vehicles 1, which must frequently start and stop, such as rail vehicles 1 in public transport.
  • the present invention thus relates to the following facts:
  • a bogie 6 has a chassis frame 7.
  • the chassis frame 7 is resiliently mounted on bearings 7b via a first spring device 7a.
  • a wheelset shaft 8 of a wheelset is mounted in the bearings 7b .
  • a wheelset 9 surrounds the wheelset 8 concentric. It acts on the wheel set shaft 8.
  • the wheelset drive 9 is supported by means of the wheel set drive 9 proprietary assigned second spring means 16 on the bearings 7b spring-loaded. Between the wheelset 9 and the wheelset 8 a two-way clutch 15 is arranged.
