Definitions

  • the present invention relates to a primary suspension for railway vehicles, that is to say a set of parts constituting an elastic connection between an axle and a bogie chassis.
  • It relates more particularly to a primary suspension for railway vehicles, comprising two axle boxes per axle, each axle box being connected to the bogie chassis by an articulation, a first spring located, relative to the axis of the wheels, of the other side of the joint, and a second spring located on the same side as the joint.
  • EP 0212348 discloses such a suspension.
  • the second spring is located in the axis of the joint, so that the forces applied to it are very large.
  • FR 1290679 discloses a progressive rubber suspension for wagons and other railway vehicles. These rubber springs can directly support the load, which means that the articulation axis of the axle box no longer experiences any reaction from top to bottom.
  • the object of the present invention is to eliminate the vertical forces applied to the joint, and this object is achieved by shifting the axis of the second spring relative to the axis of the joint, which allows better use of the flexibility. springs.
  • the support of at least one spring is done by means of a pivoting part.
  • an axle box 1 comprises two arms 2 and 3 extending horizontally on either side of the box.
  • the arm 3 is extended by an articulation 4 allowing the movement of the box on a bogie frame 5.
  • a first spring 6 extends between the bogie frame 5 and the arm 2
  • a second spring 7 extends between the bogie frame 5 and the arm 3.
  • each spring can be constituted by a group of coaxial springs of steel or elastomer.
  • the support arm 2 of the spring 6 is preferably in a horizontal plane situated lower than the plane of the support arm 3 of the spring 7.
  • each spring 6 and 7 The specific characteristics of each spring 6 and 7 are different.
  • This arrangement makes it possible to reduce the stiffening of the suspension.
