Definitions
- the present invention relates to a chassis for track-bound vehicles, in particular rail vehicles, in which the vehicle structure is based on suspension assemblies or is suspended from them.
- the invention relates both to vehicles, the structure of which is based on one or more driving units, and to vehicles in which the mutually adjacent bodies are supported on a single, common driving mechanism, 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 identical in the rest.
- Rail vehicles the undercarriages of which have a undercarriage frame consisting of at least two parts which are connected to one another in an articulated manner and which enable the wheel sets to be adjusted radially when cornering
- DE-OS 32 40 419 to reduce the rigidity of the wheel set guidance in the longitudinal direction of the vehicle.
- the radial adjustability of the wheel sets achieved by this measure which only moves within the longitudinally elastic range of the wheel set guide, however leads to uncontrolled wheel set positions which, as practice has shown, no exact adjustment of the wheel sets to the Must result in the center of the curve, but can even lead to an anti-radial setting of the leading wheel set in the track curve under unfavorable conditions.
- DE-OS 30 30 084 shows a mutually controlled radial adjustability of the wheel sets, in particular for chassis or bogies, in which each wheel set is driven by an associated 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.
- a further embodiment of making the wheel sets of a motorized undercarriage or bogie radially adjustable is shown in EP 0 072 328, although this is a forced radial adjustment of the wheel sets controlled by the vehicle body, but otherwise with regard to installation of the drive can be referred to the previously made statements.
- a further development of making wheel sets radially adjustable in accordance with one of the abovementioned possibilities, but without having to support the associated drive motor directly on the wheel axis, is formed by the undercarriage frames consisting of at least two parts which are connected to one another in an articulated manner, as is shown, for example, in FIG DE-OS 32 35 692 is shown using a very complex example.
- this solution offers the possibility of realizing the two previously mentioned modes of operation of radially adjustable wheel sets, taking into account motors that are not supported on the wheel sets, namely in the form of wheel sets that are mutually controlled or controlled by the vehicle body.
- the teaching described here is still based heavily on the original structure of a classic bogie and, in addition to the actual, articulated C-shaped subframe that carries out the control process, requires a pair of side frames and a cradle support for supporting the vehicle body.
- a further possibility of achieving the radial adjustability of the wheel sets by means of a chassis frame consisting of at least two parts which are connected to one another in an articulated manner is disclosed in DE-OS 32 12 755.
- the bogie frame is dispensed with in the usual sense and the diagonally opposite wheels of a chassis are connected by means of Z-shaped diagonal supports on which the vehicle body is spring-loaded.
- the diagonal supports can move relative to each other in the direction of travel so that the result is a radial adjustability of the wheel sets when cornering.
- the second requirement is the favorable entry and exit conditions combined with a consistently low level Vehicle floor due to an extremely low overall height of their running gear and running gear with small wheel diameters.
- the basic idea of the invention is based on the creation of motorized undercarriages and non-motorized undercarriages 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 resiliently on one another via cantilever arms and / or by means of Pendulums are resiliently suspended from these and the resilient elements of which are simultaneously able to absorb the unscrewing movement of the two half frames, resulting from the radial position of the wheel sets relative to one another in accordance with the curvature of the vehicles.
- This solution can also be designed in such a way that it can use either one of the two known modes of operation, namely mutual self-control or box-side positive control, with regard to the radial adjustability of the wheel sets.
- this solution due to its structural design, can take into account the special requirements that arise with radially adjustable wheel sets in connection with the drive and brakes. This is also shown not least by the fact that the solution is not subject to any additional loads or wear resulting from it, so that it is particularly suitable for the use of small wheel diameters.

- FIGS. 9 to 12 a plurality of undercarriage arrangements with motorized undercarriages and non-motorized undercarriages of a corresponding type, 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 FIG. 1 two wheel sets 2, 2 'are each guided in a c-shaped half frame 3, 3' at axle bearing points 10, 10 '.
- 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 1 .
- the spring elements 5 have a primary spring action and also take up the relative unscrewing movement of the two c-shaped half frames 3, 3 'resulting from cornering, without friction and as a pushing movement.
- the rotary movement takes place in the common pivot bearing 7 of the rear part of the c-shaped half frames 3, 3 ', which is formed as a connecting 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 'are each guided by a c-shaped half frame 3, 3' at axle bearing points 10, 10 '.
- a drive 16, 16 ' each consisting of a motor 13, 13' and a clutch 14, 14 'and a transmission 15, 15', and brakes 17, 17 'and / or 27, 27 are provided '.
- 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, compared to the drive wheel sets 12, 12 ', none of them come out of the curve ven mars resulting relative movements to each other.
- these are received on the one hand in the common pivot bearing 7 of the two C-shaped brackets 3, 3 'connected with connection supports 6, 6' and, on the other hand, they are removed from the spring elements 5 leads, on which the supporting cantilever arms 4, 4 'are supported on the respectively opposite c-shaped half frame 3, 3'.
- 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 simple. is controlled mutually.
- the two c-shaped half frames 3, 3 'connected to connection supports 6, 6' can move 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 pushing direction.
- the extent of the twisting movement of the two c-shaped half frames 3, 3 'relative to one another is determined by the radius of the curve 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').
- the longitudinal entrainment between the motorized undercarriage 11 or the non-motorized drive 1 and a vehicle body 20 takes place via a trailing arm 19 arranged in the longitudinal direction of the vehicle. This trailing arm engages with one end on the c-shaped half frame 3 or 3 'or in the pivot bearing 7 19, is gimbaled at its other end on a pin 18 fastened to the vehicle body 20.
- the vehicle body 20 is further supported by the vehicle box springs 9 on the corner stiffeners 8, 8 'of a motorized chassis 11 or non-motorized drive 1.
- FIG. 4 shows a motorized undercarriage 41 in a basic illustration, with the wheel sets 12, 12 'being coupled to one another by means of an axle bearing points 10', which is arranged on both sides of the motorized undercarriage 41 on the c-shaped half frame 3
- Handlebar lever system 21 This controls the wheel sets 12, 12 'from the vehicle body 20 as soon as there is a turning movement between the vehicle body 20 and the motorized chassis 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 half-frames 3, 3' and 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 enable an additional transverse elastic axis guide to be accommodated in the form of an annular, elastic element 22 (FIG. 5), or two V-shaped elastic elements 23 (FIG. 6), which also have a certain primary spring include.
- FIG. 7 is based on an axle guide in which the vehicle box springs 9 are not arranged on the corner reinforcements 8, 8 'in the manner described above, but in the form of direct support of the vehicle body 20 directly above the axle bearing 10, 10' of the c-shaped half-frames 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). From a rotationally symmetrical view, it is found that the oppositely lying c-shaped half frame 33 ', the supporting cantilever arms 34', 35 'of which are also bent differently, leads to the desired nesting of both frame halves.
- the supporting cantilever arms 34 and 35 'or 34' and 35 are thus arranged one above the other in the longitudinal direction.
- This arrangement allows the c-shaped half frames 33 and 33 'to rotate relative to one another as a result of the radial position of the wheel sets 2, 2' relative to one another, in accordance with the curvature of the vehicle 20.
- the vehicle box springs 9 can also be provided on the outer consoles on the c-shaped half frames 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 here 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, the vehicle body of which is based on two non-motorized drives 1, 31, 32 supports ( Figure 9), as well as under locomotives, especially when the individual vehicle parts are articulated to one another ( Figures 10 to 12), but also when the adjacent superstructures of two Support vehicle parts on a common drive or drive (11, 41, 42 or 1, 31, 32) ( 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, by using 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 enables 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.
