Definitions

  • a device for returning a central buffer coupling horizontally to its mid-position, particularly for rail vehicles comprises a fixed housing with a coupling pin journalled in the housing and connected with one end of a coupling rod which is rotatable thereon.
  • a guide plate which is pivotal on the coupling pin has respective opposite side faces having a pair of spaced side rollers along its side faces which engage against an oblique side surface of a ram which is slidable in the housing.
  • the ram includes a side surface extending substantially perpendicular to the vertical axis of the coupling pin which glides along a surface of the housing and a biasing surface at right angles to the glide surface which forms a base for a device which biases the ram in directions toward the coupling pins.
  • the biasing device may comprise springs or hydraulic fluid operated piston and cylinder combinations to act through the oblique surface of the ram and the rollers on the guide plate to return the central buffer coupling horizontally into its mid-position.
  • a device for horizontally resetting the central buffer coupling of a vehicle particularly a rail vehicle includes a guide member or guide plate which carries backing rollers on each of two respective opposite sides on each side of the coupling pin.
  • the backing rollers on the plate are disposed so that in the mid-position each pair of backing rollers along a side applies against a first lateral surface of a ram which has a triangular shape in plan view.
  • the second lateral surface of the ram is guided in a fixed housing surrounding the coupling pin and the third lateral surface forms an abutment of a biasing force such as a return spring so that each plate acts inwardly toward the coupling from the respective opposite sides.
  • a biasing force such as a return spring
  • the springs may be replaced by any biasing means such as hydraulic pressure.
  • a device for returning a central bufier coupling which includes a guide plate which is rotatable on a coupling pin and which includes opposite surfaces which are formed obliquely and complementary to an oblique surface of a ram member which is guided in a housing for outward and inward movement in respect to a central coupling pin and which bears against spaced rollers carried on the guide member and is biased by a biasing force to urge the guide plate into a neutral position.
  • a further object of the invention is to provide a central buffer coupling return device which is simple in design, rugged in construction and economical to manufacture.
  • FIG. 1 is a vertical sectional view of a coupling joint having a central buffer coupling return device constructed in accordance with the invention
  • FIG. 2 is a horizontal section taken on the line lIII of FIG. 1;
  • FIG. 3 is a vertical section taken along the line III- -III of FIG. 2; and I FIG. 4 is a view similar to FIG. 2 of another embodiment of the device.
  • the invention embodied therein comprises a buffer coupling which includes a coupling rod 2 and a carrier member 3 which are mounted for pivotal movement about a coupling pivot l.
  • the carrier 3 supports the free end of a leaf spring 4 which is secured at its opposite end to the coupling rod 2 and it thus holds the central buffer coupling resiliently in the mid-position.
  • a plate shaped guide member or guide plate 5 which is rotatable about the pivot 1 and is connected at least to one of the coupling rod 2 or the carrier 3.
  • the guide plate 5 is connected to the carrier 3 by means of tight fit screws 6 which are located at equal distances from pivot 1. Screws are arranged at spaced locations along respective oblique guide faces of the guide plate 5.
  • the rollers 7 are arranged in pairs which include a roller 7a and 7b rotatable around associated screws 6 at spaced locations along each oblique side face.
  • rollers 7a and 7b of each pair are acted upon by reaction biasing means in the form of a ram 8 which is biased in the embodiment shown in FIG. 2 by return springs 10 so that the ram on each side of the guide plate 5 acts to return it to a central position.
  • the ram 8 includes a first side surface 8a which extends obliquely and is parallel to the side surface of the guide plate and bears at its respective ends on each of the rollers 7a and 7b;
  • the ram also includes a second lateral surface 8b which applies against a slide surface 9a which extends at right angles to the axis a and is formed at the interior of a housing 9.
  • a third lateral surface extends parallel to the axis a and it forms a bias surface which is engaged by the return spring 10 which is disposed over a guide shank 8d which is secured to the lateral surface 8c.
  • the springs 10 are advantageously designed as a set of Belleville springs.
  • each ram member 8' has a third surface 8c which forms a bias receiving surface which in this instance is acted upon by a piston rod 8d connected to a piston 11 which is movable in a hydraulic cylinder 12.
  • the cylinder 12 is exposed to a compressed air pressure through the action of the main bolt of themechanical coupling closure.
  • the ram 8 includes a surface 8e which is recessed concentrically inwardly so that during the horizontal swinging out of the coupling rod 2' first the ram 8' whose guide shank 8d is applied against the piston 11 of the cylinder 12 is pushed back by the backing roller 7a at one side and by the backing roller 7b at the other side and the ram 8 is then exposed to a reset biasing force.
  • the two backing rollers 7a and 7b come to roll over the surface of the recess 82 which is concentrical of the pivot l and no reset force is exerted anymore on the guide member 5. or the coupling rod 2 so that the coupling rod is no longer urged back into it mid-position.
  • a central buffer coupling return device comprising a fixed housing, a coupling pin journalled in said housing, a coupling rod pivotally connected to said coupling pin, a guide plate pivotal on said coupling pin and having respective opposite side faces, a pair of rollers journalled in said guide plate to project outwardly from each side face, and reaction biasing means acting on said guide rollers on each side including a ram on each side mounted in said housing for sliding movement in directions substantially perpendicular to the axis of said coupling pin, each ram having a first oblique surface applying against said rollers, a second surface guided in said housing, and a third surface forming a lateral biasing surface, and bias means acting on said biasing surface urging said rams in directions toward said coupling pin.
  • each of said bias surfaces include a guide shank thereon, said guide shank extending through said housing and being guided therein.
  • a central buffer coupling according to claim 1, wherein said first oblique surface includes an inwardly formed recess curved so as to be concentric to said coupling pivot.
  • said biasing means comprises a fluid pressure cylinder, a piston movable in said cylinder and connected to said bias surface to move said bias surface and said ram.
  • a central buffer coupling according to claim 1 including a, leaf spring connected to said coupling rod, a carrier supported on said leaf spring and connected to said guide plate.
