Definitions

  • This invention relates to a suspension spring, particularly for railway vehlcles and it has for its object to provide means .for coupling the spring plates rigidly and 11nmovably to the spring buckle, so as to prevent displacement of said spring plates relatively to said buckle when the vehicle 1s 1n operation.
  • the problem to be solved is the provision of a spring which satisfies the requirements of railway working and the manufacturing requirements also.
  • the spring plates must not be weakenedin cross-section by drilling them through, recessing them or giving them undulating bends, the spring buckle must remain undivided and unweakened and all the parts of the spring and f its fastening must be capable of being produced inthe simplest form and as cheaply as possible and must also be interchangeable.
  • Fig. l is ka side elevation of the spring buckle and part of the spring.
  • Fig. -2 is a central sectionthrough the ET-1l I spring plates b having each in its upper face a longitudinal groove a and at its bottom face x a longitudinal rib engaging the groove of the plate below it, while said groove is engaged by the longitudinal rib of the plate above it.
  • each groove is 'considerably larger and deeper and forms a cavity or depression d, and just sothe central portion of each rib forms a downwardly directed boss d which engages the depression below it, while the depression-located just above and pertaining to the plate having that boss is engaged by the boss of the plate above it.
  • the spring plates Y) are arranged in layers, one on top of another and interengaged by means of the bosses d and boss depressions CZ.
  • rlhe lowest spring plate has its boss fitted into a corresponding boss depression in the bottom of the spring buckle 0.
  • the coupling plate e On Vthe uppermost spring plate lies the coupling plate e, the central boss d of which engages in the boss depression Z y of said plate while lateral lugs f on said couplingplate co-operate with the cheeks of the spring buckle c to keep said coupling place in position.
  • the free space above the coupling plate is filled up with a liner plate g which holds the bundle of springs in engagement with the plate e. l
  • Assembly is effected by drawing the locking member, already inserted in the spring buckle, ,overl the packet of springs, previously bundled and bound together by clamping devices until the middle is reached.
  • boss on the lowermost spring plate then springs into the boss depression of the spring buckle and the boss of the coupling plate into the boss rest on the uppermost spring plate.
  • a coupling plate contacting with one of the outermost plates of the set of plates and having at its four corners lateral lugs extending beyond ⁇ the adjacent plate; a liner plate contacting with said coupling plate, and a buckle encompassing al1 said members and having its lateral parts l0- cated between said lugs.
  • the fastening of said lining (packing) plate has been arranged in such away that the one end upper horizontal cheek of the spring buckle c, the other end of the lining (packing) plate being horizontally slotted and one end a ,bentv upwards.
  • An accidental dropping of In order to secure the lining plate in the ⁇ spring buckle any kind of arrangement may -g is set off, and in consequence close to the bination,ra plurality'of superposed elastic plates having each on one of its faces a projection located in the center portion of the plate, and in its other'face a cavity'also locatedk inv the center portion of the plate and e
