Definitions

  • the invention relates to a four-axle bogie for rail vehicles with an H-shaped main frame, which is provided in the center for supporting the car body with a rotary pan bearing and the four ends of which are supported on side walls, through which two axles are combined in pairs.
  • the axles are rigidly mounted in the side cheeks, which in turn are mounted in pairs on the main frame so as to be pivotable about a horizontal axis.
  • This design results in large lateral starting forces for the axles located at the end of the bogie, which results in high wear.
  • the invention has for its object to provide a four-axle bogie of the type described, which has good running properties while avoiding the disadvantages of the known design with a simple construction and avoids large starting forces in particular with good cornering.
  • the side cheeks are each connected to the axle bearings of the two axles by means of a support which enables a movement which is movable on all sides, and in that the main frame is supported on the side cheeks by spring elements which, apart from a travel in the vertical direction, limit a limited amount Allow rotation of each side cheek about an axis of rotation lying in the longitudinal center of the side cheek as well as limited movement in the longitudinal and transverse directions and at an angle thereto.
  • the bogie according to the invention in which the main frame is supported directly on the side bolsters while avoiding additional bearings, enables the individual axes to be automatically adjusted to the respective rail profile by the design according to the invention, so that not only large lateral jolts are avoided, but even when using identical ones Wheelsets wear on both the wheelsets and the rails is significantly reduced becomes.
  • This is achieved by the limited mobility of the side cheeks connecting two axles in each case, which can move around a pivot point lying in the longitudinal center of the side cheeks due to the supports between the axle bearings and the side cheeks designed according to the invention and the spring elements according to the invention between the side cheeks and the main frame.
  • the support arranged between each axle bearing and the associated side cheek can either be designed with a spherical bearing surface or be provided with an elastic bearing layer in order to enable the adjustment which can be moved on all sides.
  • the spring element between each end of the H-shaped main frame and the associated side cheek can be designed as a roller spring element which, in addition to the spring travel in the vertical direction and the limited rotation of each side cheek about an axis of rotation lying in the longitudinal center of the side cheek, also has a limited movement in the longitudinal direction. and transverse direction and a movement at an angle to the longitudinal and transverse directions and at the same time causes a return to the central position, so that the spring element itself is loaded with restoring forces.
  • This can also be achieved by layered rubber springs or steel springs, preferably spirally wound steel springs.
  • two spring elements are arranged next to one another in the longitudinal direction of the side cheek, as a result of which the restoring forces increase without impairing the automatic adjustability.
  • the invention further proposes to lower each side cheek in the area of the spring elements with respect to the area of the supports for the axle bearings.
  • a further development of the four-axle bogie according to the invention is achieved in that between the ends of the main frame lying one behind the other in the longitudinal direction there is in each case a support which is articulated at both ends and on which at least one slide is arranged for lateral support of the car body on the bogie. This prevents undesirable inclinations of the car body when cornering.
  • the sliders can be supported resiliently on the carrier.
  • an undesirably high inclination of the car body relative to the bogie can also be prevented by arranging between the ends of the main frame, which are arranged one behind the other in the longitudinal direction, an articulated suspension at both ends with at least one air spring element, which with its upper part is connected to the vehicle chassis.
  • This embodiment of the carrier with at least one air spring element not only results in a resilient support of the car body with respect to the bogie, but also a damping of the rotary movement of the bogie opposite the car body so that rolling movements are combated. Since the angle of rotation of the bogie relative to the vehicle undercarriage is relatively small, the air spring elements dampen the relative rotary movement without restricting this rotary movement to an impermissible degree.
  • the lower bearing part of the rotary cup bearing is arranged within the main frame in this way. is that the bearing surface is below the top edge of the main frame. This results in an integration of the rotary pan bearing lower part within the main frame and a low overall height, which is particularly advantageous when wheels of small diameter are preferably used.
  • the bogie has an overall H-shaped main frame 1, which is composed of a longitudinal member 1 a lying in the direction of travel and two cross members 1 b running parallel to one another.
  • the carriage body of the rail vehicle not shown in the drawing, is supported on the main frame 1 by means of a rotary socket bearing.
  • the lower bearing part 1c of this rotary cup bearing can be seen in the drawing.
  • the four ends of the main frame 1, each lying in pairs one behind the other in the direction of travel, are each supported on a side cheek 2, through which two wheel sets 3 are combined.
  • Each wheel set 3 comprises an axle 3a which is provided with wheels 3b of small diameter and is rotatably supported in axle bearings 4 with its laterally projecting steering knuckles 3c.
  • a support 5 is arranged between each axle bearing 4 and the side cheek 2, which enables a limited adjustment that can be moved on all sides between the axle bearing 4 and the side cheek 2.
  • this support 5 is designed for this purpose with a spherical bearing surface, as can be seen in the right part of FIG. 3.
  • the support 5 can also be provided with an elastic bearing layer.
  • the four ends of the main frame 1 are supported on the side cheeks 2 in the illustrated embodiment by two spring elements 6, as can best be seen in FIG. 2.
  • the side cheeks 2 in the area of these spring elements 6 are lowered relative to the area of the supports 5 for the axle bearings 4. This training can also be seen best in the right part of FIG. 2.
  • spring elements are used as spring element 6, the roller spring 6a of which is arranged between a lower spring plate 6b and an upper spring plate 6c.
  • This configuration can best be seen in the left part of FIG. 3.
  • these roller spring elements 6 allow limited movement of the side cheek 2 with respect to the main frame 1 both in the longitudinal direction and in the transverse direction and also movement at an angle to the longitudinal and transverse directions.
  • the above-described limited mobility within the spring elements 6 of the side cheek 2 gives the possibility of also rotating about a pivot point relative to the main frame 1. This fulcrum lies in the longitudinal center of each side cheek 2 between the two spring elements 6.
  • the wheel sets 3 have the possibility of automatically adapting to the respective rail course when passing through a curved track.
  • the described design of the supports 5 and spring elements 6 ensures that the wheel sets 3 each return to the central position, so that the bogie also runs exactly straight guaranteed.
  • a carrier 7 is arranged between the ends lying one behind the other in the longitudinal direction on both sides of the main frame 1, the ends of which are articulated on the cross members 1b of the main frame 1, as can be seen in FIGS. 1 and 5.
  • this carrier 7 carries a slider 8, on which the vehicle undercarriage 9 comes to rest when the car body is inclined.
  • the slide 8 is supported on the carrier 7 by compression springs 8a. These compression springs 8a are shown in broken lines in FIG. 1.
  • air spring elements can also be arranged, the lower part of which is connected to the carrier 7 and the upper part of which is connected to the vehicle underframe 9. These air spring elements have such a great mobility of the upper part relative to the lower part that they do not limit the slight rotational movement of the bogie relative to the vehicle underframe 9, but exert a damping effect through their restoring forces, which suppresses wobbling movements of the vehicle. With such air spring elements, not only a resilient support of the car body relative to the bogie can be achieved, but also a damping of the rotary movement.
  • an anti-lift device 10 is arranged between the main frame 1 or its cross members 1b and the side car 2.
  • a damper can be arranged if necessary, which dampens the adjusting movement of the axially arranged pairs 3 relative to the main frame 1. These dampers can be used to limit the adjustment movements at the same time.
