Definitions

the invention relates to a rail vehicle with four or six wheel sets.
rail vehicles of this type it is generally known to combine the wheel sets toward the vehicle ends in two groups, each with two or three wheel sets; these groups of wheels are usually each resiliently attached to a bogie frame.
the bogie frames are each movably connected to the vehicle body and perform the supporting function for the vehicle body.
the invention has for its object to provide a rail vehicle with four or six wheel sets controllable in the radial position in a weight-reduced design.
a rail vehicle with four or six sets of wheels, which are combined towards the ends of the vehicle in two groups, each with two or three sets of wheels, each set of wheels being connected directly and without any intermediate frame to the self-supporting vehicle body, and at the same time being used for track arching
Geometrically required transverse displacement and longitudinal displacement of the wheel sets relative to the vehicle body can be adjusted passively or actively by means of kinematics, as a result of which all wheel sets can be controlled in a radial or approximately radial position when traveling on a curved track.
the advantages that can be achieved with the invention are, in particular, that the proposed frameless rail vehicle with wheel sets attached directly to the self-supporting vehicle body is lighter and simpler than a rail vehicle with bogies of conventional design.
the saved weight allows e.g. an increase in drive power without increasing the axle load. Furthermore, there is a reduction in manufacturing costs.
the design according to the invention has the advantage that the lateral forces in the track and / or the wear on wheels and rails are significantly reduced and are approximately the same or even less than in the known vehicles with bogies
FIG. 1 shows a view of a rail vehicle when traveling on a curved track.
a self-supporting vehicle body 2 of a rail vehicle located on a track 1 can be seen.
the longitudinal axis of the vehicle body is labeled LA and the transverse axis of the vehicle body (perpendicular to the direction of travel of the vehicle) is labeled QA.
At each end of the vehicle body there are three wheel sets combined into a group. In detail, three axles 3, 4, 5 of the first group and three axles 6, 7, 8 of the second group are shown.
the two wheels of a wheelset axle are designated by numbers 9, 10. Furthermore, it is shown in Fig.
FIG. 2 shows a passive radial control of a wheelset axle 8 with wheels 9, 10, as can be used with all wheelsets.
passive radial control the transverse displacement of 12 individual wheel sets in relation to the vehicle body that occurs in the track curve is used.
pins 14, 15 are provided on both ends of the wheelset axles, which slide in guide grooves 16, 17, which are connected to the vehicle body 2.
the guide grooves 16, 17 are designed such that the pins 14, 15 inevitably experience a defined movement parallel to the longitudinal axis LA (longitudinal displacement 13) when the wheel set axis moves transversely to the vehicle body 2 (transverse displacement 12), as a result of which the wheel set axis rotates out of the normal position 11 takes place and the desired radial control is achieved.
the sketched pin / guide groove configuration 14/15/16/17 is only an example and can be replaced, for example, by linkage arrangements which use the transverse displacement 12 of the wheel sets with respect to the vehicle body 2 which occurs geometrically in the curved track in order to bring about a longitudinal displacement 13, as a result of which the radial control results. Furthermore, the controls of different wheel sets can also be mutually coupled in order to achieve an even better radial control effect.
control can be supported by the longitudinal forces that arise in a known manner in the arc due to different running circle diameters.
FIG. 3 shows an active radial control of a wheelset axle 8 with wheels 9, 10, as can be used with all wheelsets.
the ends of the wheelset axle are provided with joints 18a, 18b, into which piston rods 19a, 19b engage, which can be extended and retracted essentially parallel to the longitudinal axis LA by means of control cylinders 20a, 20b attached to the vehicle body 2.
control cylinders 20a, 20b By a corresponding installation direction of the control cylinders 20a, 20b, the required defined transverse displacement 12 of the wheel sets is achieved in addition to the longitudinal displacement 13. This results in an actively caused rotation of the wheelset axis from the normal position 11 in the direction of the radial setting.
a lever 21 is provided perpendicular to the axle of the wheelset, which is connected at its first end to the vehicle body 2 via a pivot point 25.
the second end of the lever 21 has a joint 22 and can be pivoted essentially parallel to the transverse axis QA.
a piston rod 23 of a control cylinder 24 attached to the vehicle body 2 engages the joint 22, as a result of which a rotational movement of the axle 8 about a pivot point 25 can be set.
the control cylinder is actuated, the respectively desired positions of the wheel set are achieved with transverse displacement 12 and longitudinal displacement 13 with respect to normal position 11.
the lever 21 can be fastened, for example, to the housing of the drive motor 26 of the axle 8.
auxiliary staff required for active control can be electrical, pneumatic or hydraulic.
the control specifications for these auxiliary forces - for example for the control cylinders 20a, 20b, 24 - can be dependent on the centrifugal forces occurring and detected in the track curve and / or depending on the geometric position occurring and recorded Wheel sets in the track curve and / or depending on the forces occurring and detected during track curve travel on the wheel sets.
the transverse displacements 12 of the wheel sets when traveling on a curved track parallel to the transverse axis QA are made possible either by a correspondingly large spring-loaded axial bearing play of the wheel sets or by a mobility of the wheel set axes parallel to the transverse axis QA. Adequate freedom of movement of the wheel sets is ensured by appropriate selection of the spring stiffness transverse to the vehicle longitudinal axis.
the spring stiffnesses in the transverse direction can be designed differently in the individual wheel sets in order to minimize lateral forces in the track and the wear of wheels and rails by optimal radial control.
