Definitions

  • the invention relates to a steering axle drive with coil springs, preferably for two-axle rail vehicles.
  • the steering axle drive with leaf springs and inclined double-hook suspension has been standardized and has become the standard version.
  • the leaf spring steering axle drive cannot meet higher requirements with regard to smooth running and the uninfluenced effectiveness of the steering axles when driving or braking forces are applied with one-sided block brake.
  • these steering axles tend to restlessly at certain speeds in the straight line and, under unfavorable influences, can lead to counter-radial settings in the track curve.
  • DE-PS 928105 calls a solution preferably for a two-axle light rail car using drawbar drives.
  • the automatic setting of a freely rolling wheel set in the track is influenced as a result of the distance between the wheel set and the pivot point and articulation point of the drawbar, and is further falsified in the action of lateral wind and centrifugal forces.
  • DE-GM 9305427 shows a solution for a single-axle running gear in the sense of a steering axle running gear with primary spring elements below and secondary spring elements above a running gear frame. This is coupled to a crossbar above the wheel set, with N- or V-shaped handlebars. This is rotatably attached to the base frame of the car body by means of a pivot pin.
  • a pair of forces occurs on the elements mentioned in the case of drive or braking forces, which is compensated by a counter-directed force pair between the rigid vertical handlebar or spring-loaded tension / compression rod and both side secondary suspension elements, which leads to vertical spring reaction. No significant lateral suspension is suggested.
  • DE-PS-604 283 shows yet another solution, wherein wheel set links are arranged between the wheel set and the vehicle frame.
  • the invention is based on the object of providing a running gear for two-axle rail vehicles which enables automatic radial adjustment in the track curve, in which the straight line runs smoothly, largely avoids counter-radial adjustment under extreme conditions with little installation space.
  • the difference between a steering axle drive and a drawbar drive lies in the position of the fulcrum when the wheel set is adjusted radially. While the pivot point is in the center of the free steering axle, the pivot point in a drawbar drive is arranged at a considerable distance from the center of the wheelset to the drawbar pivot point.
  • the existing lever arm enables the lateral forces to influence the wheel set adjustment.
  • FIGS 1 to 3 show a steering axle drive with a variant of a compensating device 5 in the form of a compensating lever 6 with different storage of the same.
  • An axle or wheelset link 1 is based on an axle or wheelset bearing 2 with the interposition of a cardanic elastomer pad 3 and is connected at its end by an elastic spherical bearing 4 to the compensating device 5, which is designed here as a compensating lever 6.
  • the compensating lever 6 has the center of rotation in an elastomer bushing 7, which is fastened to the center of the vehicle.
  • the longitudinal forces are transmitted from the vehicle via the compensating lever 6 and the two axle or wheel set control arms 1 to a wheel set 8.
  • the vertical mounting of the compensating lever 6 takes place on both sides either through a sliding guide 30 as shown in FIG. 1, or by means of Spacers on a hanger 9 as long as possible, as shown in FIG. 3, with elastomer bushings 7a on a base frame or vehicle frame 27 and on the compensating lever 6.
  • compensating lever 6 both axle or wheel control arm 1 and the wheel set 8, the latter can turn under the vehicle with a fictitious pivot point in the center of the wheel set (indirect linkage).
  • a further prerequisite for the rotation of the wheel set 8 is formed by the coil springs 10 which transmit vertical forces and are designed with a defined lateral rigidity. These are mounted at the top with intermediate or parallel connection of a suspension travel limiting device 11 on the base frame or vehicle frame 27 and are supported on the axle or wheel set control arms at the bottom 1.
  • the suspension travel limiters 11 also limit the horizontal movements of the axle or axle control arm 1 with the participation of longitudinal and transverse spring-loaded side stops 12.
  • the travel downward is limited by collar nuts 13, which are screwed onto the suspension travel limitation device 11 and the hoisting of the drive enable.
  • the upper limit of the spring travel takes place by means of a resilient stop 15 between the underframe or vehicle frame 27 and the axle or axle control arm 1.
  • the symmetrical design of a disc brake system 16 is attached to a gimbal-type suspension device 17 according to FIG.
  • This consists of upwardly bent longitudinal beams 18 which are gimbal-mounted on the compensating lever 6 or a compensating shaft 23 or small deflection angle 29 by means of a ball bushing 19 and rotatable at the top by means of a disk bearing 20 with an upward bent cross member 21 is connected.
  • the cross member 21 is connected at both ends by the ball bushings 19 to the two axle or wheel set arms 1.
  • Ball bushings 19 and disc bearings 20 are designed to be inelastic to avoid frictional vibrations of the disc brake system 16.
  • a hydraulic damper 22 is arranged vertically between the underframe or vehicle frame 27 and the axle or wheel set bearing 2 or axle or wheel set link 1 on both sides.
  • a hydraulic damper 22 which is articulated between one end of the compensating lever 6 or a lever 24 of the compensating shaft 23 or outer deflection angles 29 and the underframe or vehicle frame 27 is sufficient for damping the longitudinal movements of the wheel set 8.
  • the lateral movements of the wheel set 8 are damped by the hydraulic damper 22, which is located between the axle or wheel set link 1 and the underframe or vehicle frame 27.
  • FIG. 4 A further variant of the balancing device 5 is shown in FIG. 4, in which the balancing shaft 23 is used.
  • the balance shaft 23 is inclined in such a way that the elastic-spherical bearings 4 of the axle or axle control arms 1 articulated on the corresponding levers 24 lie on a horizontal line I - I.
  • the inclined bearings of the balance shaft 23 in the form of elastomer bushings 7 are fastened to the underframe or vehicle frame 27 and transmit the longitudinal forces.
  • the balance shaft 23 the same effect is achieved as with the balance lever 6.
  • the downstream parts of the drive are the same as in the first variant according to FIGS. 1 to 3, so that the description is omitted here.
  • the variant in FIG. 5 contains an asymmetrical arrangement of the disc brake system 16 and an eccentric axle drive 25.
  • the asymmetrically arranged disc brake system 16 hangs on a cardanically asymmetrical suspension device 17a.
  • This consists of a Y-shaped, upwardly bent longitudinal beam 18a, which is articulated at the bottom by means of a ball bushing 19 on the compensating lever 6 or on levers 24 of the compensating shaft 23 on the line I - I.
  • the ends of the Y-shaped, upwardly bent longitudinal member 18a are connected and rotatably connected to the upwardly bent cross member 21 by means of disk bearings 20 (FIG. 6).
  • the cross member 21 is gimbally connected at both ends by ball bushings 19 to the axle or axle control arm 1.
  • the off-center axle gear 25 has a torque support 26, which transmits the reaction forces of the drive to the drive.
  • the end of the torque arm 26 is articulated via an elastic spherical bearing 4 on the levers 24 of the balance shaft 23 on the line I - I or on the balance lever 6.
  • FIG. 7 Another variant of the compensation device 5 is shown in FIG. 7, in which a compensation rod 28 is used. This variant is used when the installation space is very limited from above.
  • the compensating rod 28 laterally transmits the longitudinal forces emanating from the axle or wheelset control arms 1 for adjusting the axle by interposing deflection angles 29.
  • This drive differs advantageously from the known drives in that its low height makes it suitable for low-floor vehicles. In addition, the drive is relatively light.
