Definitions

  • the invention relates to a chassis for rail vehicles, in particular for light rail vehicles, with two wheels rotating independently of one another with or on separate wheel axles and horizontally pivotable with them about separate pivot axes, the pivoting movement of both wheels being coupled to one another via a tie rod.
  • Trolleys of conventional design are designed as bogies with wheelsets.
  • the bogies equipped with conventional wheel sets must be designed with rigid wheel set articulation in order to suppress or complicate the undesired shaft running of the wheel sets.
  • the stiff wheel set hindering the run in tight curves.
  • the wheels cannot assume a radial position in the track curve.
  • Even adjusting the bogie under the vehicle can only partially adjust the wheels radially.
  • the skewing of the wheels relative to the rail resulting from this imperfection results in undesirable wear on the wheels and rails. This phenomenon is not affected by idler gears which are arranged on a wheelset shaft, are mounted independently of one another on the shaft and can be rotated without mutual influence of torque.
  • bogie undercarriages are only used to enable the partial and imperfect adjustment of the wheels on track curves.
  • the two wheelsets in the two-axle bogie are far from being fully utilized due to the total vehicle weight.
  • the leading wheel set of a bogie only serves to control the radial setting of the bogie in the track curve.
  • Bogies are therefore not only of limited suitability for low-wear sheet travel, but also heavy and complex because of the unnecessary second wheel set.
  • DE-C-887 665 discloses a chassis of the generic type in which two wheels rotating independently of one another on separate wheel axles can be pivoted horizontally about separate pivot axes arranged between the two wheels.
  • a mechanical control device is provided, which essentially consists of a coupling half and an associated linkage mounted on the vehicle. Horizontal swiveling movements of the wheel pairs are forced when cornering by turning the coupling halves of vehicles that are coupled to one another. Wheel pairs on non-coupled. Vehicle ends of a train or of individual vehicles cannot execute swiveling movements because of the control device then not working.
  • the FR-A-809 635 can be removed from a bogie with individual wheels connected to a vehicle body via a central pivot point.
  • the separate axles of these wheels can be swiveled horizontally about swivel axes, the transverse distance of which is greater than the transverse distance of the points of contact of the wheels with the rails.
  • a control device acting on the wheel axles and articulated on the vehicle body also provides swiveling movements of the wheels.
  • the undercarriage to be created by the invention is intended on the one hand to allow good guidance of the vehicle in a straight track even at very high driving speeds and on the other hand to guarantee low-wear, constraint-free running in the narrowest bends with small track bend diameters, the safety of the guidance must be guaranteed in any case.
  • the invention is therefore based on the object to enable the construction of light undercarriages for rail vehicles which can be operated safely at high speeds on straight tracks and in narrow bends with little wear on wheels and rails.
  • each wheel of a four-wheeled vehicle or undercarriage can assume the ideal radial setting in the curved track.
  • the setting of the wheels of the pair of wheels in the track curve takes place on the one hand through the so-called profile forces which arise in the track curve as a result of changed contact geometry between wheel and rail and on the other hand due to the non-positive forces arising between wheel and rail due to the kinematics of the wheel movement.
  • the profile forces and the frictional forces about the swivel axis generate moments which initiate a swivel movement of the wheels.
  • the swiveling movement comes to a standstill when the moments from profile and frictional forces are in balance.
  • the moments can be influenced individually by the lever arm, without the size of the forces occurring changing.
  • FIGS. 8 to 10 a force F-way s diagram with different characteristics for the steering suspension 11 after Fig. 7 is shown.
  • the vehicle 1 or chassis shown in outline has a pair of wheels at the front and rear.
  • a pair of wheels consists of two wheels 2, each arranged at the same distance from the longitudinal axis 1 a of the vehicle.
  • the bearings 3 of these wheels 2 are mounted on wheel axles 5, which are each firmly connected to a steering lever 4.
  • the steering levers 4 of two opposite wheels 2 of a pair of wheels can be rotated horizontally about pivot axes 6 formed on the vehicle or chassis side and are connected to one another in an articulated manner by a tie rod 7.
  • the intersection points of the swivel axes 6 have the same horizontal distance A from the chassis or vehicle longitudinal center 1a as the contact points 8 of the wheels 2 with the through a plane placed on the rails 9 of a track (here the plane of the drawing) Rails 9 (distance B).
  • Rails 9 distance B
  • the points of intersection of the pivot axes 6 of the front pair of wheels in the direction of travel (Pfpil X) lie behind the contact points 8 of the wheels 2 with the rails 9; the points of intersection of the pivot axes 6 of the rear pair of wheels lie in front of the points of contact 8 of the wheels 2 with the rails 9 (see the longitudinal distances C).
  • the penetration points of the pivot axes 6 have a greater horizontal distance A from the longitudinal center 1a of the vehicle than the contact points 8 of the wheels 2 with the rails 9 (distance B), the penetration points of the pivot axes 6 being at the same longitudinal distance C. 'from the vehicle center 1 b are like the points of contact 8 of the wheels 2 with the rails 9.
  • the penetration points of the pivot axes 6 can in turn be offset differently with respect to the contact points 8 of the wheels 2 with the rails 9 both transversely to the longitudinal center 1 a of the vehicle and longitudinally to the center 1 b of the vehicle. This results in the transverse distances A and B and the longitudinal distances C and C 2 , as shown.
  • a one-piece frame 10 is provided in a known H-shaped design (two side members and one cross member). 5 a frame formed from halves 10a and 10b is possible, the halves 10a and 10b being connected to one another via joints 10c. In this way, the frame pins 10a and 10b are movable around the diagonal 10d with a view to compensating for unevenness in the rails.
  • Both the one-piece frame 10 and the frame halves 10a and 10b have the pivot axes 6 for the wheels 2.
  • the horizontal pivoting motion of the wheels 2 may be supported g 11 Derun about the pivot axis 6 by a symmetrical Lenkungsfe-, which is held on one side to the tie rod 7 and on the other hand, in the vehicle-side fixed points 11a.
  • the characteristic of the steering suspension 11 can be bent out linearly according to FIG. 8 or progressively or degressively according to FIGS. 9 and 10.
  • a steering damping according to FIG. 12 is recommended, which is also connected to the tie rod 7 and fixed points 12a on the vehicle.
  • a combination of the steering suspension 11 and the steering damping 12 is easily possible.
