Definitions

  • the present invention relates to a primary type suspension for railway vehicles as per the preamble of claim 1, the evident object of which is to constitute a device providing an independent two-wheel and short shaft bogie with a primary suspension for railway vehicles, allowing vertical displacements of the suspension independently of each wheel, maintaining, as a consequence, a parallelism and a separation between same.
  • This invention applies to the industry devoted to manufacture railway vehicles and accessories.
  • the inventor is, at present, aware of the existence of different primary suspension systems, but none of them has, in fact, an efficient performance of its elements composing it, which results in a deterioration of the carried wheels.
  • the primary type suspension for railway vehicles proposed by the invention constitutes, a solution to the current problem in this field.
  • the envisaged primary type suspension for railway vehicles is constituted starting from an articulated dual connection rod having two horizontal shafts, which, by means of two bushings coupled to the bogie structure, and other two bushings coupled to a part common to a bearing box, acts as a guide for the suspension spring or springs.
  • the suspension has two bars articulated at its ends joining the bearing boxes with the bogie structure, so allowing the wheel and short shaft assembly to carry out a vertical and parallel displacement, as well as the bearing boxes, and, furthermore, by means of a strip joining the inner bearing boxes, independent vertical displacements of each of the two bearing - sets are possible, so maintaining a full and absolute separation between them .
  • the vertical suspension is obtained by distortion of the spring or springs mounted between the bearing boxes and the bogie frame.
  • the side suspension is obtained by distortion of the resilient bushings, the axial characteristic of which is relatively soft in relation to its radial one which is harder, allowing some millimeters of separation simultaneously shown at the two wheels - since both bearing sets are joined through a strip.
  • the envisaged primary type suspension for railway vehicles is constituted starting - from an articulated dual connecting rod 1 pivoting at two horizontal shafts A and B, which, through two bushings 2, joined with the bogie structure 3 and other two bushings 4 joined with a part 5 common to the bearing box 6, 7, acts as a guide for the suspension spring or springs 11.
  • the invention contemplates two bars 12 mounted on supports 14 , articulated at their ends and joining the bearing boxes with the bogie structure 3, allowing the wheel set 8 and the short shaft 9 and bearing boxes 6, 7 to vertically and parallel displace.
  • Solidly connected with the bogie frame 3 is a plate 13 by means of which the bogie rests on the springs 11, slides along the parts 5 and is thus resiliently and vertically movable, the bogie being accompanied in its vertical movement by the bushings 2 attached to it. This allows a movement of the connecting rod 1 about the two axes A and B formed by said bushings 2 and 4.
  • the vertical suspension is obtained by distortion of the spring or springs 11 which are mounted between the bearing boxes and the bogie structure, while the side suspension is obtained by distortion of resilient bushings 2, 4, the axial - characteristic of which is relatively soft in relation to the radial one which is harder, so allowing some millimeters of displacement simultaneously shown at the two wheels, since - the bearing sets are joined through said strip 10.
  • bearing boxes 7 are united to the bogie structure 3 by means of a bar 12, which is articulated at its ends, which, together with the connecting rod 1, allows each of the bearing sets to carry out independent vertical and parallel displacements .
  • the primary suspension has resilient bushings 2, 4 which permit transverse displacements which are caused by side efforts transmitted to the wheel through the track and that, - due to the resilient characteristics of the bushing, act as a side primary suspension.
  • the springs 11 can be substituted by rubber sandwiches of appropiate dimensions.
