Definitions

  • the present invention relates to a bogie for a rail vehicle with at least two wheel sets and at least one passive steering device, which each pivotably connects two wheel sets to one another and has a third control lever provided with a pivot point for pivotably connecting to a car body, and a rail vehicle.
  • DE-PS 31 19 164 As an active steering device in the prior art, the embodiment shown in DE-PS 31 19 164 is known, the horizontally arranged linkage of which is actuated in normal operation by means of a piston-cylinder unit via a control unit, which receives its impulse from an encoder which does this Game of the flange of a wheel to the inside edge of the rail detected.
  • Passive steering devices derive their adjustment movement directly from the turning angle, which is only available in sufficient size when cornering through the car body moving relative to the bogie.
  • CH-PS 183 368 has already attempted to create a steering device which is arranged horizontally between the body and the bogie and uses its relative turning movement.
  • the articulation point of the car body is on the inside, i.e. its distance from the common longitudinal median plane of the car body / bogie is smaller than the corresponding distance of the bogie-side fixed point by which the rod is unscrewed.
  • CH-PS 644 806 Another, also horizontally arranged steering device is shown in CH-PS 644 806, which has an internal articulation point of the car body with respect to the bogie-side fixed point. Otherwise, this version is extremely complex in that an attempt is made to generate a non-linear lever movement for the steering of the wheel sets by means of a four-bar linkage and correspondingly increased pivot points. This is intended to achieve stable vehicle running on straight sections and progressively increasing leverage with increasing section curvature.
  • the present invention has for its object to provide a bogie with a passive steering device for rail vehicles, especially for vehicles with small radii, such as trams and light rail vehicles, with at least one steering device being arranged approximately horizontally between the bogie and car body, and their relative turning movements be used as an adjustment variable for the wheel set control so that the rubber-elastic elements used in the pivot and articulation points of the steering device sought are optimal in terms of their angle of rotation.
  • leading and trailing wheelsets of a bogie should m.W. are forcibly aligned with the center of the curve due to the relative unscrewing movement between the car body and the bogie due to cornering by means of at least one, preferably horizontally arranged linkage.
  • the invention solves this problem according to the wording of claim 1 by, because of its special arrangement, it offers the known advantages of a steering device (avoidance of sheet running noise, longer service life of the wheel sets) and at the same time the to date has been able to prevent disadvantages associated with the use of such devices (high wear in the pivot points).

  • the ratio of the distances includes the relation of a distance b1 or b2 of the associated articulation point 28 or 29, as the point of application of the control rod 26 or 27 in question on the respective wheel set 3 or 3 ⁇ , compared to a distance b5 of the outer articulation point 21 to their common Longitudinal median plane 4.
  • the ratio describes the relation of a distance b4 of a fixed point 23 on the bogie 2, 2 ⁇ , around which the turning movement of the steering device 20 takes place, with respect to a distance b5 an external articulation point 21, to the common longitudinal median plane 4.
  • a comparative analysis of the effect of a steering device 10 with an internal articulation point 11 compared to a steering device 20 with an external articulation point 21 shows clear disadvantages for the latter type in relation to the twist angle ⁇ of the rubber-elastic elements 9.
  • a passive steering device 30 which is arranged horizontally in a bogie 2, 2 ⁇ and has an “internal negative” articulation point 31 of the body 1, such that the articulation point 31 extends over the longitudinal center plane 4 protrudes.
