Definitions

  • the invention relates to a wheelset guide with a virtual wheelset pivot axis with the features of the preamble of claim 1, which are known from EP 0 143 540 B1.
  • a drive bogie of a rail vehicle is disclosed, the frame of which is supported on the two wheel sets via vertically approximately rigid, but laterally (in the driving range) shear-elastic shear blocks.
  • the internally mounted wheelsets are each positively guided by a handlebar that creates a connection between the wheelset bearings and the body of the rail vehicle.
  • the cutters are designed as rectangular rubber-metal cushions and four are arranged on both sides of each wheel set so that their elongated longitudinal axes converge in a vertical axis in the space between the side cheeks of the bogie and the two wheel sets that extend clearly outside the central longitudinal axis .
  • This axis of rotation lies in the area of an elastic coupling with which torques are transmitted from a drive motor to the gear set.
  • the wheel sets controlled by their handlebars, can be adjusted radially in the track by swiveling around the eccentric virtual axis of rotation.
  • ring-shaped bushes equipped with a rubber-elastic element are used as primary spring elements, which also have different spring stiffnesses in one plane depending on the direction due to recesses in the rubber-elastic elements, so that their stiffness depends on the Driving speed can be set variably.
  • the invention is based on the object, based on the wheel set guidance discussed at the outset, of specifying a simpler solution which does not require a handlebar.
  • a two-axle bogie - two wheel sets 3 and 4 are rotatably supported about their axes of rotation 3A and 4A according to the plan view shown in FIG. 1 , with their outer bearing housings 5 and the frame between them 1 primary spring elements 6 are arranged.
  • the wheel sets 3 and 4 are pulled through in their normal position (standstill or driving in a straight line) and drawn in dashed lines in a steering position (driving in an arc).
  • the axes of rotation 3A and 4A are set against one another in the latter position, that is to say the wheel sets are pivoted radially into the arc, the included angle here being the Clarification is exaggerated. Really occurring swivel angles are much smaller.
  • Arrows F pointing to the left in the rotation axes 3A and 4A on the right-hand side represent centrifugal forces acting on the frame 1.
  • Arrows L pointing to the right are shown in the center of the wheelset shafts, which represent the guidance or straightening forces exerted by the outer rail (left) on the wheelsets 3 and 4 or their flanges.
  • the dashed-line steering position of the two wheel sets 3 and 4 is set in this chassis alone and handlebar-free under the action of forces F and L, because the primary spring elements 6 of a wheel set are arranged and executed in mirror symmetry on both sides of the longitudinal center axis LM of the chassis so that they are in Driving given in two directions different, with respect to the direction of travel and centrifugal direction oriented spring stiffnesses, the axes of the lowest spring stiffnesses outside the axis of rotation 3A or 4A of the wheel sets 3 or 4 intersect in a longitudinal projection of the center of the wheelset or on the longitudinal center axis LM, as is shown here through intersections of the axis LM and two dash-double-dotted lines of action.
  • the helix angles of these lines of action are not representative of a real arrangement, but of course have to be adapted to the requirements of the real vehicle.
  • the direction of the lowest spring stiffness with respect to the axis LM (direction of travel) is rotated by approximately 45 °, and it must also be able to be set in a range between 10 and 60 ° in the real vehicle.
  • each wheel set in the driving plane is set around a vertical virtual axis of rotation V, which ideally intersects the axis of rotation 3A or 4A of the wheel set in the center of the wheel set, but at least should pass through the wheel set shaft.
  • FIG. 1 This is preferably achieved by a special design of the primary spring elements only indicated in FIG. 1 as multi-layer rubber-metal elements according to the sectional view in FIG. 2.
  • the section through the primary spring element 6 is again parallel to the plane of travel, as by coordinate arrows x (direction of travel) and y (direction of tracking or centrifugal force) is indicated.
  • An — preferably oval — outer ring 6R encloses an elastomer body 6K, which in turn comprises an elongated central central body (sword) 6M.
  • the components that abut each other in a flat manner are non-positively connected to each other (e.g. vulcanized).
  • An arrow h shows the line of action of the greatest spring hardness of the element 6
  • an arrow w indicates the line of action of the lowest spring hardness.
  • Recesses 6A are preferably provided in the elastomer body 6K in the direction of the arrow w.
  • the resilience of the elastomer body 6K with respect to deformations in this direction can be adjusted with their size.
  • the size of these recesses is determined according to requirements; if necessary, they can also extend up to the center body 6M, so that, in contrast to the embodiment shown, no more elastomer material is present at its tips and the elastomer body is divided into two parts.
  • the primary spring element is resilient and flexible even in the vertical direction (arrow z).
  • a weight G acts downward on the center body while the outer ring 6R is held.
  • this arrangement could be reversed if necessary, so that the middle body fixed to the wheelset is then inserted from bottom to top into the elastomer body and the outer ring is attached to the frame.
  • the elastomer body 6K has to form a connection, which is shearable mainly in the directions w and z, between the outer ring 6R and the center body 6M.
  • the hardness of the elastomer body can be adjusted in all directions in a known manner, depending on the choice of material and its geometry, within wide limits.
  • the type of primary spring element is not important for achieving the self-steering effect according to the invention. Rather, other types, e.g. B. rolling ring springs or trapezoidal multi-layer spring elements can be used as long as the spring stiffnesses are aligned and coordinated in the manner described above.
  • a primary spring element can also be provided on each wheel set side on both sides of the axis of rotation.
  • they are supported in pairs in a manner known per se on the wheel set bearing.
  • the vertical loads of the individual primary spring elements are halved.
