Definitions

  • the invention relates to a device for locking the end positions of movable switch parts, in particular moving points frog pieces, in which two relatively axially displaceable parts in a force-locking or positive-locking in at least one direction of movement coupled position are displaceable, wherein the relatively movable parts of a tube and a rod guided in the tube are formed and at least partially disposed in a stationary outer tube and the locking members cooperate with the mutually axially displaceable parts and the outer tube and are displaceable in the radial direction in a locking position in a recess or mecanicringnut the outer tube.
  • the invention now aims to develop a device of the type mentioned in such a way that even during the changeover as well as in the end position in the radial direction impermissible surface pressures can not be exceeded, which could lead to plastic deformation. Furthermore, the training of the invention aims to facilitate the assembly and disassembly.
  • the inventive construction essentially consists in that the locking members of rings or ring segments are formed, whose substantially square or rectangular cross-section is chamfered at its two inner sides to form obliquely to the axis converging surfaces.
  • rings or ring segments which carry at least on its inner side at both ends obliquely to the axis converging surfaces, it can be ensured that during the expansion of the rings or ring segments a surface contact is ensured, on which restoring forces or holding forces, which lead to a widening or compression of the rings or ring segments can be absorbed without risk of plastic deformation. It thus be avoided during the changeover plastic deformation with certainty and the inclined surfaces in the manner of wedge surfaces to move the rings in the locking position effectively. At the same time, the number of components required is eliminated by eliminating the balls and the fasteners required for the balls, as ball cage, clamping bolt od.
  • this training can also be used for multiple locking levels and in particular for the adjustment of movable points frog pieces, in which high actuating forces and high locking forces must be absorbed and the lock is required in each case two different layers. In such multiple locking levels, the improved by the lower cross-sectional weakening stiffness and the improved resistance moment of the inner tube is of particular importance.
  • the training is such that the chamfer angle ( ⁇ ) of the tapered inclined surfaces between 20 and 35 ° to the radial center plane of the rings and is formed parallel to inclined abutment surfaces of the rod.
  • ⁇ the chamfer angle
  • Such a choice of the chamfer angle or the inclination of the inclined surfaces to the radial center plane causes only low frictional forces must be overcome with relatively low actuating forces and maintaining a surface contact in order to move the rings or ring segments in their respective other position.
  • the inward displacement of the rings or ring segments can be favored by using springs which extend over the circumference of the ring segments.
  • the inward movement can also be initiated by an analogous external chamfering, with the advantage that the formation is made such that the chamfering on the inner and outer circumference of the rings or ring segments is provided.
  • the rings or ring segments may be formed expandable against the force of a spring.
  • the design is such that the expandable ring consists of at least 3, preferably 4, connected by a circumferential tension spring segments.
  • Optimal surface contact between the ring or ring segments and the rod is achieved by the curvature of the inner surfaces of the rings or ring segments corresponding to the curvature of the outer rod diameter.
  • a further improvement results if, as corresponds to a preferred development, the curvature of the outer surfaces of the rings or ring segments at least partially corresponds to the curvature of the inner diameter of the outer tube.
  • FIG. 1 shows a first shift position of rings or ring segments with locking of a right end position in the drawing
  • Fig. 2 shows the embodiment of FIG. 1 during the changeover
  • Fig. 3 shows the lock in the left end position, as is required for switch frogs
  • Fig. 4 shows a section along the line, IV-IV shown by formed as a ring segments locking members.
  • Fig. 1 an inner tube 2 and a rod 3 is guided relative to each other in an outer tube 1 movable.
  • the inner tube 2 has radial openings 4.
  • grooves 5 are provided, in which dive in the locking position rings or ring segments 6.
  • the ring segments 6 are displaced outwards, wherein they accumulate on a erit Kirend formed with a larger diameter portion 7 of the inner rod 3 and are displaced outwardly in this way and immerse in a first groove 5 of the outer tube 1.
  • the rod 3 has spun areas 8, in which the rings 6 can dip during the adjustment and thus disengaged and thus reach a position in which a shift without locking succeeds. This is illustrated in FIG. 2.
  • the curvature of the inner surfaces 13 of the rings or ring segments is adapted to the curvature of the outer rod diameter. Existing holding or vibration forces can thus be absorbed particularly gently.
