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.
