Definitions

  • the invention relates to a self-steering, three-axle bogie with steering beam according to the preamble of the independent claims 1 and 4.
  • Such a self-steering, three-axle bogie with steering beam is known from DE 38 24 709 C2.
  • a railroad vehicle is described with a car body supported by a bogie with at least two wheel / axle arrangements, the bogie containing a bogie frame with two parallel side members, which are connected by at least one transverse beam extending transversely thereto and the bogie frame from the axles
  • Primary suspension means is carried, which allow yawing movements to run along a curved track.
  • a first transmission linkage connects the axles to the bogie frame and includes at least one transverse steering beam which is connected to an axle and has a pivotally connected center to the bogie frame to steer the associated axle to improve its radial position and to allow transmission of longitudinal forces between it and the bogie frame.
  • the car body is supported on the bogie frame by elastic secondary spring means, which are arranged laterally spaced in the direction of opposite sides of the bogie frame, the bogie containing at least three wheel / axle arrangements.
  • the invention has for its object to provide a self-steering, three-axle bogie with steering beams of the type mentioned, in which the center wheel set is also involved in the control system.
  • the horizontal spring deflection forces of the wheel set springs opposing the control movement are more easily overcome, and in particular in the case of small radii of curvature, in which larger horizontal deflections are required for the radial position If the wheelset springs are required, the alignment of the wheelset shaft to the center of the bow is improved.
  • FIG 1 a first variant of a drive with coupling via two steering beams is shown.
  • a three-axle bogie for a rail vehicle can be seen, which has a bogie frame, not shown, consisting of longitudinal and cross members.
  • the wheels of the wheel sets are designated with number 11.
  • the wheel sets can be driven by drive motors (not shown) (for example Tatzlagermotoren or rack motors).
  • the wheelset bearing housings 2, 3, 6, 7 of the two outer wheel sets 8, 10 can be moved, inter alia, in the direction of travel or opposite to the direction of travel of the rail vehicle, which is indicated by directional arrows x1, x2.
  • the wheelset bearing housings 4, 5 of the center wheel set 9 can be moved, inter alia, perpendicular to the direction of travel of the rail vehicle, which is indicated by directional arrows y1, y2.
  • two steering beams 12 and 13 are provided, each with fixed frame pivot axis 14 and 15 (vertical axis). These pivot axes 14, 15 are each located on the longitudinal center of the vehicle.
  • joints 16 are provided, which are used to couple the individual wheel set bearing housings of the outer wheel sets via handlebars to the steering beams.
  • wheelset bearing housings 2 are connected to the steering beam 12 via a handlebar 17
  • wheelset bearing housings 3 are connected to the steering beam 12 via a steering rod
  • wheelset bearing housings 6 are connected to the steering beam 13 via a handlebar 19
  • wheelset bearing housings 7 are connected to the steering beam 13 via a handlebar 20.
  • the joints for attaching the handlebars to the wheelset bearing housings are marked with number 21.
  • the coupling between the steering beam and the wheelset bearing housings of the center wheel set is carried out via handlebar rods 22 and angle levers 26, 27, the joints for connecting the handlebar rods to the steering beams being numbered 24 and the joints for connecting the handlebar rods to the first arms of the angle levers being numbered 25 are.
  • the joints 24 are at a greater distance from the longitudinal center of the vehicle than the joints 16.
  • the angle levers have axes of rotation 28 fixed to the frame and are connected via joints 29 via their second arms to the end faces of the wheel set bearing housings of the center wheel set. Specifically, there is a coupling from the steering beam 12 via the handlebar 22 and the angle lever 26 to the wheel set bearing housing 5 as well as a coupling from the steering beam 13 via the handlebar 23 and the angle lever 27 to the wheel set bearing housing 4.
  • these wheelset bearing housings are provided with joints 32, on which the longitudinal links 30 and 31, respectively are attached, the other ends of which lead to frame-fixed joints 33.
  • the mode of operation of the self-steering, three-axle bogie 1 according to FIG. 1 is described below.
  • the configuration of wheelset bearing housings 2, 3, 6, 7 with joints 21 - handlebar rods 17, 18, 19, 20 - steering beams 12, 13 - handlebar rods 22, 23 - angle levers 26, 27 - wheelset bearing housings 4, 5 with joints 29 results in connection with the wheelset bearing housings 2, 3, 6, 7 of the outer wheel sets 8, 10 which are movable in the direction of travel / opposite to the direction of travel (x1, x2) of the rail vehicle and the wheelset bearing housings 4, 5 which are movable perpendicular to the direction of travel (yl, y2), a counter-coupling of the outer wheel sets Turning the vehicle.
  • the wheelset bearing housing 2 moves in the x2 direction
  • the wheelset bearing housing 6 must inevitably move in the x1 direction and the wheelset bearing housing 4 must move in the y1 direction.
  • the wheelset bearing housing 3 move in the x1 direction, the wheelset bearing housing 7 in the x2 direction and the wheelset bearing housing 5 in the y1 direction.
  • the same components as described in FIG. 1 are present in the second variant of a drive shown in FIG. 2 with a coupling via two steering beams.
  • the components are each identified by simple deletions, that is, bogies 1 ', wheelset bearing housings 2' to 7 ', wheelsets 8' to 10 ', wheels 11', steering beams 12 ', 13', swivel axes 14 ', 15', joints 16 ', handlebars 17 'to 20', joints 21 ', handlebars 22', 23 ', joints 24', 25 ', angle lever 26', 27 ', axis of rotation 28', joint 29 ', trailing arms 30', 31 'and joints 32', 33 '.

  • the handlebar 22 ′′ is arranged between the joint 24 ′′ of the steering beam 12 ′′ and the joint 25 ′′ of the angle lever 26 ′.
  • the steering beam is elongated in comparison to the design according to FIG. 1, a joint 40 ′′ being arranged at this elongated end, which serves to fasten a steering rod 41 ′′, which on the other hand forms an angle lever 27 ′.
