Definitions

  • a trackbound vehicle comprising a first and a second car, the longitudinal axes of which form an angle, interconnected at a joint and rotatable in relation to each other around an axis of rotation, which passes through the joint, a number of bogies, each of which has a bogie frame, at least one wheel axle attached to the bogie frame and at least two wheels with each wheel rigidly connected to a wheel axle, wherein a first bogie is arranged rotatable around the mentioned axis of rotation, which is centred between the wheels .
  • the conventional technique for providing long trackbound vehicles with wheel arrangements is based on utilization of bogies, that is, rotatable, load-carrying structures comprising two or more wheelsets, wheel axles and suspension.
  • bogies that is, rotatable, load-carrying structures comprising two or more wheelsets, wheel axles and suspension.
  • the concept car body in this context is defined as the device which is intended to contain and/or constitute the base for the payload.
  • the number of bogies and hence also the weight of the vehicle are reduced by placing two-wheeled bogies between the car bodies .
  • Bogies placed in the manner described are known as Jacobs bogies .
  • Jacobs bogies structures are often used which are interconnected at joints which may be in common with the joints in which the bogies are rotatable.
  • the car bodies are placed spring- mounted on the structures .
  • the wheel axle in a single-axle frame must be given a possibility of steering through track curves, while at the same time it is desired to counteract tendencies to oscillation and hunting movement of the bogie when driving at higher speeds .
  • the wheel axles in a trackbound vehicle should be set radially or almost radially to the track curve if negotiation of the curve is to be performed without friction and without major wear of wheel and rails.
  • Steering a wheel axle through a track curve entails adjusting the wheel axle radially to the track curve, but may as well be expressed such that the wheels are adjusted and roll in the direction of tangent of the rails and almost tangentially to the direction of tangent of the rails.
  • the technique which is most closely related to the present invention is the principle for active steering of wheels in a railway vehicle which is described in the publication "The tilting talgo", Elekthari Bahnen, 5/1985, pp 156-162, 6/1985, pp 82-85.
  • the technique which is described in that publication is based on the provision of linkage arms connected between a two-wheeled Jacobs bogie and the car bodies both behind and in front of the bogie, on both sides thereof.

  • the disadvantage of the above-described technique is that rolling motion of a car body, as a result of, for example, oblique loading, will provide a steering deflection of the bogie.
  • During assembly of the vehicle it has to be ensured that the bogie is perpendicular to the track in case of a straight track. From the points of view of service, cost and reliability, it may also be a disadvantage to use completely mechanical steering systems.

  • the mechanical construction may be made considerably less expensive compared with current constructions, while at the same time the angular adjustment is not influenced by oblique loading of the car body. Nor does the construction require the same precision during the assembly as a completely mechanical solution.
  • One aspect of the invention is to align the bogies at the ends of the trackbound vehicle at the same angle in relation to the car as the nearest bogie in relation to the same car.
  • the wheel axles in the bogies at the ends of the trackbound vehicle will then be aligned perpendicular to the track.

Ce véhicule comprend également un certain nombre de bogies (5) possédant chacun un châssis (7), au moins un essieu (10) fixé sur le châssis du bogie, ainsi qu'au moins deux roues (8, 9), reliées chacune de manière rigide à l'essieu, un premier bogie étant monté rotatif autour dudit axe de rotation, lequel est centré entre les roues. Ce véhicule comprend en outre un premier dispositif de mesure (21) de l'angle (α) entre les axes longitudinaux de la première et de la seconde voiture, un actionneur (20) destiné à aligner le premier bogie par rapport aux voitures, ainsi qu'un module de calcul (22) produisant, en fonction de l'angle mesuré, un signal en direction de l'actionneur, lequel doit alors aligner les essieux afin que ceux-ci soient parallèles à la bissectrice (19) de l'angle formé par les axes longitudinaux des voitures.
