Definitions
- the invention relates to a rail vehicle with four or six wheel sets.
- rail vehicles of this type it is generally known to add the wheel sets to the Summarize vehicle ends in two groups, each with two or three wheel sets; these groups of wheels are usually resilient on a bogie frame attached.
- the bogie frames are each movably connected to the vehicle body and exercise the carrying function for the vehicle body.
- all wheelsets when traveling in curved track to control radial or almost radial position (self-steering bogie).
- the invention has for its object a rail vehicle with four or six in specify radial position controllable wheelsets in a weight-reduced design.
- This task is solved by a rail vehicle with four or six wheel sets, which towards the vehicle ends in two groups, each with two or three wheel sets are summarized, with each wheelset directly and without any intermediate frame the self-supporting vehicle body is connected and at the same time the at Track curve geometrically required transverse and longitudinal displacement the wheelsets are passive or active in relation to the vehicle body using kinematics is adjustable, which means that all wheel sets when traveling on a curved track are radial or approximate radial position are controllable.
- the advantages that can be achieved with the invention are, in particular, that the proposed frameless rail vehicle with directly on the self-supporting vehicle body attached wheelsets is lighter and easier than using a rail vehicle Bogies of conventional design.
- the saved weight allows e.g. a Increase in drive power without increasing the axle load. Furthermore results a reduction in manufacturing costs.
- the invention offers Execution the advantage that the lateral forces in the track and / or wear Wheels and rails are significantly reduced and approximately the same or even less are like the known vehicles with bogies
- FIG. 1 shows a view of a rail vehicle when traveling on a curved track. It is a self-supporting vehicle body 2 located on a track curve 1 Recognize rail vehicle.
- the longitudinal axis of the vehicle body is LA and the transverse axis of the vehicle body (perpendicular to the direction of travel of the vehicle) is labeled QA.
- the Both wheels of a wheelset axle are designated by numbers 9, 10. Furthermore, in Fig.
- FIG. 2 shows a passive radial control of a wheelset axle 8 with wheels 9, 10, as it can be used with all wheelsets.
- For the passive radial Control is the transverse displacement of 12 individual wheel sets in the track curve pulled towards the vehicle body.
- This includes, for example Pins 14, 15 are provided on both ends of the wheelset axles, which are in guide grooves 16, 17 slide, which are connected to the vehicle body 2.
- the guide grooves 16, 17 are designed such that the pins 14, 15 when the wheel set axis moves transversely to the vehicle body 2 (transverse displacement 12) inevitably also one experience defined movement parallel to the longitudinal axis LA (longitudinal displacement 13), whereby a rotation of the wheelset axis from the normal position 11 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 the in the track curve geometrically arising transverse displacement 12 of the wheel sets opposite use the vehicle body 2 to bring about a longitudinal displacement 13, which results in radial control.
- Mutual coupling can also be used
- the controls of different wheel sets are run to one more to achieve better radial control effect.
- control can be carried out in a known manner longitudinal forces arising from different running circle diameters are supported.
- FIG. 3 shows an active radial control of a wheelset axle 8 with wheels 9, 10, as it can be used with all wheelsets.
- control cylinders 20a, 20b attached to the vehicle body 2 are retractable and extendable essentially parallel to the longitudinal axis LA.
- a lever 21 is provided perpendicular to the axle of the wheelset, which on its first end is connected to the vehicle body 2 via a pivot point 25.
- the second end of the lever 21 has a joint 22 and is substantially parallel to the Cross axis QA swiveling.
- a piston rod 23 engages one on the vehicle body 2 attached control cylinder 24 on the joint 22, causing a rotary movement the axle 8 can be set about a pivot point 25.
- the lever 21 can, for example, on the housing of the drive motor 26 of the axle 8 can be attached.
- active radial control concepts can be used, which include radial control effect or at least support.
- the ones required for active control Assistants can be electrical, pneumatic or hydraulic.
- the Control specifications for these assistants - for example for the control cylinders 20a, 20b, 24 - can, depending on the centrifugal forces occurring and recorded in the track curve and / or depending on the occurring and detected geometric position of the Wheel sets in the track curve and / or depending on those occurring during track curve travel and detected forces on the wheelsets.
- the transverse displacements 12 of the wheel sets when traveling on a curved track parallel to the transverse axis QA are either by a correspondingly large spring-loaded thrust bearing play of the wheelsets or by a mobility of the wheelset axles parallel to the transverse axis QA enables.
- spring stiffness across the vehicle's longitudinal axis a sufficient possibility of movement of the wheel sets is ensured.
- the spring stiffness in Transverse direction for the individual wheel sets to be executed differently through optimal radial control a minimization of lateral forces in the track and the To achieve wear of wheels and rails.
