Definitions

  • the invention relates to a self-steering three-axle Drive for a rail vehicle according to the generic terms of independent claims 1 and 2.
  • DE 41 40 126 A1 is a running gear for rail vehicles known with three driven wheel sets which are elastically mounted in a bogie or vehicle frame and in which through a steering linkage that arises when driving through bends Rotational movements of the first wheel set and the third wheel set around vertical axes with the transverse movement guided by trailing arms of the second wheel set are coupled.
  • From DE-A-41 42 255 is a drive for rail vehicles with radial control of the wheel sets known, in which the transverse movement the middle wheel set with a lever on the semi-trailing arm the end gear sets is transmitted so that between the end gear sets lying wheel sets are controlled so that they are centrifugal forces transferred to the outer rail.
  • the invention has for its object a self-steering triaxial running gear for a rail vehicle of the type mentioned Specify the way in which a transverse movement of the center wheel set hindering horizontal restoring forces of the primary springs be overcome.
  • a self-steering, three-axle bogie for a Rail vehicle which also includes the center wheel set transfers lateral forces to the rails due to centrifugal force, and thereby the lateral forces caused by centrifugal force be reduced to the outer wheel sets.
  • the active actuator acts on each wheel set Third part of centrifugal force.
  • those of the tax movement opposing a transverse movement of the center gear set and rotational movements of the end wheel sets hindering horizontal restoring forces of the primary springs overcome.
  • self-steering three-axle drive that all three wheelsets for Control can be used when cornering.
  • each wheelset transfers the corresponding centrifugal force to the axle load for the three-axle bogie
  • each end wheel set is about half of the lateral forces caused by centrifugal force if no special precautions are taken so that the Center gear set the centrifugal force corresponding to the wheel set load transmits.
  • Figure 1 is a bogie with an active actuator between Center wheel set and bogie shown, such The centrifugal force component is shifted to the center wheel set, that all three wheel sets each a third of those caused by centrifugal force Transfer lateral forces to the rails.
  • the bogie 1 has one of parallel Side members 2, 3 and parallel cross members 4, 5 existing Bogie frame on.
  • Wheelset bearings 6 to 11 of the three axes 12 to 14 via not shown Wheelset springs attached, namely wheelset bearings 6, 7 for the first axis 12 assigned to the first drive motor 16 (Outer axle, outer wheel set), wheelset bearings 8, 9 for the second (middle), assigned to the second (middle) drive motor 17 Axle 13 (center wheel set) and wheel set bearings 10, 11 for the third, axis 14 assigned to the third drive motor 18 (outer axis, Outer wheel set).
  • Wheelset bearing 9 cannot be seen in FIG. 1, however shown in Figure 2.
  • the wheelset bearings 6, 7, 10, 11 of the two outer axles 12, 14 are inter alia in the direction parallel to the longitudinal beams 2, 3 of the Bogie frame, i.e. in the direction of travel or against Direction of travel of the rail vehicle is movable, which is indicated by directional arrows x1, x2 is indicated in each case.
  • the wheelset bearings 8, 9 the central axis 13 are parallel, among other things, in the direction to the cross beams 4, 5 of the bogie frame, i.e. perpendicular movable to the direction of travel of the rail vehicle, what by Direction arrows y1, y2 is indicated in each case.
  • the impellers driven by Tatzlagermotoren 16 to 18 are denoted by 15.
  • control cylinder 22 (generally: active actuator) provided, the movable piston 21 via a piston rod 20 with a joint 19 on the center wheel set 13, 8, 9 - e.g. on the drive motor 17 - attacks.
  • the control cylinder 22 is on the other hand via a connecting rod 23 with a joint 24 on Side member 3 of the bogie frame attached.
  • control cylinder 22 acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder.
  • the control cylinder can be connected via connecting lines be pressurized in a suitable manner so that the Piston 21 and the piston rod 20 an additional pressure force or tractive force exerted between the center wheel set and the bogie that additionally pushes the center wheel set towards the outside of the bend or pulls.
  • the control cylinder 22 is controlled in Dependence of the centrifugal force and / or the radius of the arc. As a result, the active actuator (control cylinder) the center wheel set with a centrifugal force component and relieved the end wheel sets accordingly.
  • the actuating force then only has to be correspondingly higher than that Centrifugal force share of the center wheel set.
  • Figure 2 is a bogie with an active actuator between Center wheel set and vehicle body shown, the at Quasi static transverse deflection occurring at centrifugal force avoided or reduced between the vehicle body and the bogie becomes. At the same time, the center wheel set becomes a transmission by centrifugal force on the track around the two end wheel sets to relieve.
  • the bogie 1 has all of those described above in FIG. 1 Components 2 to 18, but not the components 19 to 24.
  • a control cylinder 28 is provided, the movable piston 27 via a piston rod 26 with a Joint 25 on the center wheel set 13, 8, 9 - e.g. on the drive motor 17 - attacks.
  • the control cylinder (generally: active actuator) 28 is on the other hand via a connecting rod 29 with a joint 30 attached to the vehicle body 31.
  • control cylinder 28 acts transversely to the direction of travel e.g. a double-acting compressed air or hydraulic cylinder.
  • the control cylinder can be connected via connecting lines be pressurized in a suitable manner so that the Piston 27 and the piston rod 26 an additional pressure force or tractive force exerted between the center wheel set and the vehicle body that pushes or pulls the vehicle body inwards.
  • the control cylinder 28 is controlled as a function of centrifugal force and / or the radius of the arc.
  • the active actuator control cylinder
  • the reaction force acts on the vehicle body and reduces the deflection of the transverse suspension.
  • the amount of steering force corresponds to that to be transmitted from the center wheel set Centrifugal force component plus the spring force for turning the end gear sets and the spring force of the center gear set by the arrow height of the track arch between the end wheel sets arises.
  • the share of the possible provision of the centrifugal deflection Vehicle body / bogie is in relation to the bogie weight to the vehicle body, from the arc radius and from the horizontal Return force of the wheelset springs dependent.
  • the centrifugal load on the center wheel set becomes higher chosen as that of the final wheelsets, which is because of its lower dynamic Cross loading is possible, so the provision the centrifugal deflection can be further increased.
  • distribution the centrifugal force on the three wheel sets and radial position of the wheel sets can be reached.
