Definitions

  • the present invention relates to a chassis for track-bound vehicles, in particular rail vehicles, in which the vehicle body is supported on chassis arrangements or is suspended from them.
  • the invention relates both to vehicles, the structure of which is supported on one or more undercarriages, and to vehicles in which the adjacent superstructures are supported on a single, common undercarriage, in particular when the individual vehicle parts are connected to one another in an articulated manner.
  • the present invention is based on motorized undercarriages which, if the drive is omitted, can optionally also be used as drives which are otherwise identical.
  • Trolleys or bogies of rail vehicles are known, the wheelsets of which are also guided in parallel by known means in order to ensure stable straight running by means of a wheel set guide which is rigid to rigid in the longitudinal direction of the vehicle, in particular in the case of fast-moving vehicles.
  • DE-OS 30 30 084 shows a mutually controlled radial adjustability of the wheel sets, in particular for bogies or bogies, in which each wheel set is driven by an associated motor.
  • the problem that arises here which entails radially adjustable wheel sets in relation to drive and brakes, is solved in the present case in that no relative movements resulting from the radial adjustability of the wheel sets are caused between the motor and wheel set, and between the brake and wheel set, in that the motors supported on the one hand on the wheel axles are connected to one another pivotably about a vertical axis and the brakes are suspended on a brake beam connected to the respective motor.
  • a disadvantage of this concept appears to be the fact that the mutually controlled radial adjustability of the wheel sets must be brought about via the motor housing and the motors must always be supported on the wheel axles for this.
  • the basic idea of the invention is based on the creation of motorized undercarriages and non-motorized drives of largely identical construction, the load-bearing components of which consist of two half frames, which are articulated on the one hand about the vertical axis and which are supported on the other by cantilevers and / or by means of pendulums are suspended from these and whose resilient elements are able to simultaneously absorb the unscrewing movement of the two half-frames, resulting from the radial position of the wheel sets in relation to the curve travel of the vehicles.
  • This solution can also be designed in such a way that, with regard to the radial adjustability of the wheel sets, it is basically either one of the two known operating modes, namely can operate the mutual self-control or the box-side forced control. In both cases, this solution can take into account the special requirements that arise in the case of radially adjustable wheel sets in connection with the drive and brakes due to its structural design.
  • Figure 1 A non-motorized drive in perspective.
  • FIG. 2 A top view of a motorized undercarriage analogous to the embodiment according to FIG. 1.
  • Figure 3 The schematic diagram of a motorized chassis with mutually controlled, radially adjustable wheelsets, according to Figure 2.
  • Figure 4 The schematic diagram of a motorized chassis, according to Figure 3, but with radially adjustable wheelsets controlled on the car body side.
  • FIG. 5 A motorized undercarriage, according to FIG. 2, or a non-motorized undercarriage according to FIG. 1 with an additionally cross-elastic, ring-shaped axle guide.
  • Figure 6 A motorized undercarriage, according to Figure 2 or non-motorized undercarriage according to Figure 1 with additional transverse elastic, V-shaped axis guide.
  • FIG 7 A motorized chassis, according to Figure 2 or non-motorized drive according to Figure 1 with direct support of the vehicle body
  • Figure 8 A non-motorized drive in perspective.
  • FIGS. 9 to 12 A plurality of undercarriage arrangements with motorized undercarriages and non-motorized undercarriages of a corresponding design, which are particularly suitable for light rail vehicles, the undercarriages and undercarriages having small wheel diameters and permitting a continuously lower vehicle floor.
  • a non-motorized drive 1 shown in Figure 1 two sets of wheels 2, 2 'in a c-shaped first or second half frame 3, 3' at axle bearings 10, 10 'out.
  • the c-shaped half frames 3, 3 'each have two supporting cantilever arms 4, 4', which are each supported by a spring element 5 on the opposite c-shaped half frame 3, 3 '.
  • the spring elements 5 have a primary spring action and also take the resulting from the cornering, relative unscrewing movement of the two c-shaped half frames 3, 3 'frictionless and springy as a pushing movement.
  • the rotary movement takes place in the common pivot bearing 7 of the rear portion of the c-shaped half frame 3, 3 'formed as connection support 6, 6'.
  • FIG. 2 shows the top view of the drive according to Figure 1, but in a motorized version.
  • a motorized undercarriage 11 two drive wheel sets 12, 12 'of a c-shaped first or second half frame 3, 3' are guided on axle bearing points 10, 10 '.
  • a drive 16, 16 'consisting of a motor 13, 13' and a clutch 14, 14 'and a transmission 15, 15' is provided, as well as brakes 17, 17 'and / or 27, 27'.
  • the drives 16, 16 'and the brakes 17, 17' and 27, 27 ' are installed in the c-shaped half frame 3, 3' in such a way that, relative to the drive gear sets 12, 12 ', there are no relative movements to one another resulting from cornering surrender.
  • the vehicle box springs 9 are arranged on the corner stiffeners 8, 8 '.
  • Figure 3 shows the motorized chassis 11 shown in Figure 2 in a schematic diagram. It is particularly clear that the radial adjustability of the wheel sets 12, 12 'is mutually controlled in a simple manner. It can move the two, with connection supports 6,6 'connected, c-shaped half frame 3, 3' about the vertical axis in the common pivot bearing 7. This rotary movement is taken up by the spring elements 5, which support the supporting cantilever arms 4, 4 'with one another or on the respective c-shaped half frame 3, 3', in the direction of thrust.
  • the extent of the unscrewing movement of the two c-shaped half frames 3, 3 'relative to one another is determined by the curve radius on which the wheel sets 12, 12' adjust radially towards the center of the curve, without resulting relative movements between the drive 16, (16 ') or the brakes 17, (17 '), or 27, (27') and the wheelset 12, (12 ') arise.
  • the longitudinal entrainment between the motorized chassis 11 or the non-motorized drive 1 and a vehicle body 20 takes place via a longitudinal link 19 arranged in the vehicle longitudinal direction. This, with its one end on the c-shaped first or second half frame 3 or 3 'or in the pivot bearing 7, acts on the longitudinal link 19, is gimbaled at its other end on a pin 18 fastened to the vehicle body 20.
  • the vehicle body 20 is also supported on the vehicle box springs 9 on the corner stiffeners 8, 8 'of a motorized chassis 11 or non-motorized drive 1.
  • Figure 4 shows a motorized chassis 41 in a schematic diagram, with a coupling of the wheel sets 12, 12 'to each other by a on the axle bearing 10' attacking, arranged on both sides of the motorized chassis 41 on the c-shaped half frame 3 handlebar-lever system 21.
  • the wheel sets 12, 12 'from the vehicle body 20 are forcedly controlled as soon as there is a turning movement between the vehicle body 20 and the motorized undercarriage 41 or the non-motorized drive 31 as a result of cornering.
  • Figures 5 to 7 show the axle bearing 10, 10 'at the ends of the c-shaped first or second half frame 3, 3' or 33, 33 'in conjunction with a drive wheel set 12, 12' or wheelset 2, 2 mounted there 'As further embodiments that can be used in combination or as an alternative to the solutions shown.
  • FIGS. 5 and 6 make it possible to accommodate an additional transverse-elastic axis guide in the form of an annular, elastic element 22 (FIG. 5), or two V-shaped elastic elements 23 (FIG. 6), which also include a certain primary suspension effect.
  • Figure 7 is based on an axle guide, in which the vehicle box springs 9 are not arranged in the manner described above on the corner stiffeners 8, 8 ', but in the form of a direct support of the vehicle body 20 directly above the axle bearing 10, 10' of the c- shaped half frame 3, 3 'and 33, 33' are provided.
  • FIG. 8 Another advantageous further development is disclosed in FIG. 8.
  • the example of a non-motorized drive 32 shows a c-shaped half frame 33, the two supporting cantilever arms 34, 35 of which are bent differently, namely once upwards (34) and once downwards (35).
  • the supporting cantilever arms 34 and 35 'and 34' and 35 are arranged one above the other in the longitudinal direction.
  • This arrangement allows a mutual unscrewing movement of the c-shaped half frames 33 and 33 'resulting from the radial position of the wheel sets 2, 2' to each other, corresponding to the curvature of the vehicle 20th
  • vehicle box springs 9 serve as inner corner stiffeners 8, 8 'formed rear parts of the c-shaped half frame 33, 33' in the connection area of the connection supports 6,6 '.
  • vehicle box springs 9 can also be provided on outer brackets on the c-shaped half frame 33, 33 ', or the direct support shown in FIG. 7 can be used.
  • FIGS. 9 to 12 show rail vehicles in which the vehicle body 20 is supported on the most varied of chassis arrangements of motorized undercarriages 11, 41, 42 and / or non-motorized drives 1, 31, 32.
  • the present invention can be used in the form of motorized undercarriages 11, 41, 42, or non-motorized drives 1, 31, 32 of largely identical construction, for example under trailer vehicles whose vehicle structure is supported on two non-motorized drives 1, 31, 32 (FIG 9), as well as under traction vehicles, in particular when the individual vehicle parts are articulatedly connected to one another (FIGS. 10 to 12), or also when the adjacent superstructures of two vehicle parts are on a common driving or running gear (11, 41 , 42 or 1, 31, 32) support ( Figure 12).
  • Such a running gear can therefore be designed as a motorized running gear 11, 41, 42 or non-motorized running gear 1, 31, 32 of largely identical construction. It can adapt to all selected chassis arrangements and, through the use of drive and wheel sets 12, 12 'or 2, 2' with small wheel diameters for a vehicle 20 in addition to inexpensive entrances and exits 38, also enable a continuously lower vehicle floor 39.
  • the articulated design of the motorized undercarriages 11, 41, 42 and the non-motorized undercarriages 1, 31, 32 enables good maneuverability in curves, so that noise and wear and tear are largely avoided even when driving on narrow curves.
