Definitions

  • the proposed device relates to railway transport.
  • a known leash of a railway vehicle trolley (see RF patent J ⁇ L2217632 of 11/27/2003, class F 16Fl 1/00), containing a rod, ends connected with pairs of elastic conical ring elements with an oval section.
  • a disadvantage of the known device is the uncertainty of the structural design of the elastic ring elements, which does not allow to optimize the design of the leash.
  • Elastic elastic elements especially of complex shape, cannot be accurately calculated and therefore their design can be determined by manufacturing samples of elastic elements and testing them in an elastic device, i.e. selection method.
  • the specified result in the proposed device is achieved by the fact that in the leash of the trolley of a railway vehicle containing a rod, the ends connected with pairs elastic cone-shaped ring elements with an oval cross-section, a change in its longitudinal elasticity with a change in normal operating loads within ⁇ is in the range of 2000-6000 kg / cm, and a change in its longitudinal stiffness under the action of loads exceeding normal operating loads within ⁇ is in the range of 4000 -13000 kg / cm, where ⁇ is the difference between the final and initial value of the load in the corresponding range.
  • Pairs of elastic ring elements can be combined into elastic damping blocks.
  • the longitudinal stiffness can vary between 2600-4600 kg / cm, and under the action of loads exceeding standard operating loads, the longitudinal stiffness can vary from 4600-10000 kg / cm.
  • FIG. l shows one possible design for the leash.
  • Figure 2 shows the stiffness characteristic of the leash.
  • the leash comprises a rod 1 with stops 2, an elastic damping unit including internal and external rubber elastic elements 3 and 4, a hollow bolt 5 and a fixing bolt 6 screwed into the rod.
  • the shape and preload of the elastic elements are selected in such a way that, under normal operating loads of up to 2.5 tons, the axial rigidity of the leash does not exceed 6000 kg / cm, while the most optimal is the change in stiffness in the range of 2000-3000 kg / cm.
  • the stiffness limit of 6000 kg / cm is due to the fact that when this value is exceeded, the bending moment on the leash in the vertical plane increases sharply.
  • the limitation of the increase in longitudinal stiffness to 10,000 kg / cm is due to the fact that, with a rigidity of more than 10,000 kg / cm, indicators such as lateral acceleration of the car body along the pivot, vertical rise of the ridge to the rail head, side reaction between the wheel and the rail, and power friction on the rim and crest.

Abstract

L'invention concerne le transport ferroviaire et notamment l'amélioration de la barre d'un bogie. Pour optimiser le fonctionnement de la barre, on choisit la variation de sa rigidité longitudinale dans la gamme de 2000-6000 kg/cm sous l'effet d'une charge d'utilisation normale.
