Definitions

  • the invention relates to a device for fixing wheel control arms, in which the wheel control arm is designed free of openings and engages behind claws, which claws are fixed to a fastening part, the claws being able to be passed through openings in the fastening part.
  • Wheel control arms are used whenever it is necessary to avoid starting the wheel on other upper track components, especially frogs or a heart tip.
  • the wagon axis is guided by the wheel on the opposite side of the heart piece by means of a wheel control arm.
  • Various designs are known for fixing wheel control arms and it is known, for example, to fix wheel control arms to a wheel control chair in a conventional manner by means of a screw connection, as can be seen, for example, from DE-U-70 06 310. With such a design, it is necessary to drill the wheel control arm at certain intervals in accordance with the threshold division. Since different threshold divisions are used in different turnout geometries, a pre-drilled wheel control arm can usually only be used for a certain turnout geometry.
  • Wheel links can also be fixed without such bores and without screwing through, it having already become known from US-A 947 317, for example, to clamp wheel links via claws with a wheel steering chair.
  • the claws were fixed rigidly to the wheel handlebar chair by means of a screw connection, whereby a second claw is required for lowering the wheel handlebar by abutment of the wheel handlebar on a rib of the wheel handlebar chair in order to prevent the wheel handlebar from tipping over.
  • the entire wheel steering had to be replaced are made because adjustments were not readily possible due to the chosen geometry of the definition.
  • the invention now aims to provide a device of the type mentioned in the introduction, in which any necessary maintenance work can be carried out quickly and with the least effort and in which a simple possibility is provided without openings in the area of the wheel control arm, if desired by the wheel control arm Fix and support spring tension.
  • the design according to the invention aims to be able to carry out maintenance work, such as a spring replacement, without using complex aids in a very short time when using spring elements.
  • the device according to the invention essentially consists in that the fastening part has a fastening plate extending parallel to the longitudinal direction of the wheel control arm for a flat contact of the wheel control arm, that the claws can be passed through openings in the mounting plate and that the claws with the interposition of a spring and / or can be clamped against the mounting plate by detachable spacers.
  • a mounting plate extending parallel to the longitudinal direction of the wheel control arm is provided, a simple, safe and flat support of the wheel control arm is provided transversely to the longitudinal direction of the rail, and the claws can be braced against such a mounting plate quickly and with minimal assembly effort.
  • the mounting plate which extends parallel to the longitudinal direction of the wheel control arm, also allows the arrangement of spacers in a simple manner in order to be able to take account of signs of wear on the wheel control arm without replacing the wheel control arm and to set the required clear width of the wheel control arm groove or the required guidance distance with simple means.
  • the type of attachment with claws passing through the attachment plate also enables the arrangement of springs to be arranged in a particularly simple manner to achieve spring-loaded bracing and thus secure support for the wheel control arm, while the training also offers the option of safely setting the selected spring preload again without complicated adjustment work if spacers are used to compensate for the enlargement of the wheel control arm groove or to reduce the guide distance due to wear.
  • a particularly quick and reliable fixing can be achieved according to the invention in that the claws have a transverse bore on their free end facing away from the wheel control arm for receiving a clamping wedge.
  • Such clamping wedges can interact with springs, a defined spring force being achieved directly by driving in the clamping wedge.
  • such clamping wedges can also cooperate with another wedge, the design preferably being such that the clamping wedge which can be driven into the transverse bore of the claws interacts with a wedge which has a surface which corresponds to the wedge surface and which can be supported against the fastening plate. In this case, however, only a rigid, but quickly producible, secure connection is achieved, the desired tensioning force resulting from the length taken or the gear ratio of the wedges.
  • transverse or vertical wedges as clamping wedges offers particular advantages, in particular for spring-loaded fixing.
  • the training is so made that the spring is formed by at least one leaf spring or a helical spring and that the wedge cooperates with supporting surfaces of the fastening part to exert a tensile force on the claws.
  • Spacers are arranged which can be implemented between the wheel control arm and the mounting plate, the thickness of the spacer elements, measured in the direction of the tensile force on the claws, preferably corresponding to the maximum permissible wear on the surfaces of the wheel control arm facing the wheel flange.
  • a new wheel control arm is built in such a way that the spacers are arranged between the spring and the mounting plate, and with increasing wear such spacers can be inserted from this original position into a position between the surface of the wheel control arm facing the mounting plate and the mounting plate. After a tensioning wedge has been driven in again, the originally specified tensioning force is immediately achieved, so that further adjustment work is unnecessary.
  • a particularly stable construction is obtained if the design is such that the fastening plate is formed in one piece with the base plate or ribbed plate and that the stops for the clamping wedge of openings in cross-sections extending to the fastening plate and adjoining the fastening plate are supporting plates of the fastening part are formed.
  • a one-piece design can be designed as a welded construction, the fastening plate, together with the wheel chair, also being able to be designed as a drop-forged or cast construction.
  • the forces to be absorbed in the longitudinal direction of the rail are absorbed as frictional or frictional forces between the wheel control arm and the fastening plate, and the forces occurring transversely to the longitudinal direction of the rail are absorbed by the wheel control arm and transmitted directly to the fastening plate.
  • Thrust forces can be caused not only by friction from the mounting plate extending parallel to the longitudinal direction of the wheel control arm, but also from the wheel control chair in a substantially vertical direction Direction are recorded, the design preferably being such that the fastening part is designed as a wheel handlebar chair, the surfaces of which face the wheel handlebar form support surfaces for the foot of the wheel handlebar.

  • a wheel control arm 1 is pressed onto a fastening plate 2 running in the longitudinal direction of the wheel control arm by means of a hook or claw 3.
  • the contact pressure of the wheel control arm 1 against the mounting plate 2 is adjusted via a leaf spring 4, which is arranged on the side of the mounting plate facing away from the wheel control arm with the interposition of spacers 5, via a clamping wedge 6 penetrating the claw 3, which prestresses the leaf spring 4.
  • the fastening plate 2 is formed in one piece with a base plate or rib plate 7, with the fastening plate 2 also providing support plates 8 which extend transversely to the fastening plate and adjoin it.
  • the support plates 8 have recesses 10 and 11 which are aligned with the transverse bore 9 of the claw and which, in addition to the leaf spring, can serve as stops when driving in the clamping wedge 6.
  • the rail 12 cooperating with the wheel control arm 1 is also fixed, for example via screw connections 13, the fixing of the base plate on thresholds, not shown, being indicated by means of screw connections 14.
  • screw connections 13 the fixing of the base plate on thresholds, not shown, being indicated by means of screw connections 14.
  • other known connecting elements between the rail 12 and the base plate can of course also be used.
  • Ribbed plate 7 is used.
  • the fastening part formed from the fastening plate 2 and the support plates 8 running transversely thereto forms the wheel handlebar chair, the surfaces facing the wheel handlebar being designed as support surfaces for the foot 15 of the wheel handlebar chair.
  • the leaf spring 4 used in the design according to FIGS. 1 and 2 is supported on the rear side of the mounting plate facing away from the wheel control arm 1 with the interposition of the spacers 5 and presses the wheel control arm 1 onto the front of the mounting plate via the clamping wedge 6 and the claw 3. Normal forces on the wheel control arm 1 are derived directly on the mounting plate. Thrust forces are transmitted to the mounting plate 2 via friction.
  • the spacer plates 5 are installed in different thicknesses and corresponding numbers and are also braced.
  • the spacer plates 5 are located on the side of the mounting plate facing away from the wheel control arm 1 between the latter and the leaf spring 4 Wheel handlebars released by removing the clamping wedge 6 and a corresponding number of spacer plates 5 are positioned between the wheel handlebar 1 and the mounting plate 2, which in turn sets the correct guide distance and wheel handlebar groove.
  • the size of the tension of the leaf spring 4 and thus the contact pressure of the wheel control arm 1 thus remain the same, since the effective distance between the wheel control arm 1 and the plane of the leaf spring by converting the spacers 5 from the position shown in FIG. 1 into a position between the wheel control arm 1 and the mounting plate 2 has not been changed.
  • the fastening plate 2 is welded to the rib plate or base plate 7 and the support plates 8.
  • a drop forging or cast construction could also be used.
  • the opening in the mounting plate 2 for the passage of the claw 3 is denoted by 16 in FIG. 1, while a corresponding passage opening in the leaf spring and in the spacers is denoted by 17 and 18, respectively.
  • FIGS. 1 and 2 the reference numerals of FIGS. 1 and 2 have been retained for the same components.
  • a spring ring or a spiral spring 19 is used in this embodiment, which in turn is clamped over the clamping wedge, the clamping wedge penetrating the recesses 10 and 11 of the support plates 8.
  • the wheel control arm 1 is pressed against the fastening plate 2 by means of two self-locking wedges.
  • a cross wedge 6 is used, which interacts with a second wedge 20, which extends normally to the driving direction of the cross wedge 6.
  • the cross wedge or clamping wedge 6 is driven into the bore 9 of the claw 3 or into the bores 10 and 11 of the support plates 8 and by supporting the second wedge 20, which runs normally thereto, on the surface of the fastening plate facing away from the wheel control arm 1, the wheel control arm 1 becomes over the claw 3 pressed against the front of the mounting plate 2.
  • spacers 5 are used which, as wear progresses, from the position shown in FIG. 5 between the mounting plate and the second wedge 20, analogously to the previous embodiments, into a position between the side surface of the mounting plate 2 facing the wheel control arm and the wheel control arm 1 can be arranged.
  • the claw for holding the wheel handlebar 1 on the wheel handlebar chair formed by the mounting plate 2 and the support plates 8 in turn penetrates the opening 16 of the mounting plate 2 and engages behind the foot 15 of the wheel handlebar 1.
  • the tensioning and fixing of the Radlenkers 1 takes place at this embodiment by a screw connection 21, a spring ring or a similar spring element 22 being used between the spacers 5 and the nut 21.
  • the part of the claw 3 facing away from the wheel control arm 1 is provided with a corresponding thread.
  • the spring ring 22 is clamped over the nut 21 and the wheel link 1 is again pressed onto the mounting plate 2 via the claw 3.
