Definitions

  • the present invention relates generally to the connection of a bush for railway axles to the frame of a bogie of a railway vehicle, for example, a locomotive.
  • connection mechanism of the type comprising a longitudinal push rod having one end connected to the bush and the opposite end connected to the frame of the bogie with the interposition of respective elastic members formed by rubber sleeves designed to allow the bush free displacements in the vertical plane and limited displacements in the transverse and longitudinal directions.
  • the object of the present invention is to provide a mechanism of the type specified above which allows the optimisation of the transverse resilience of the connection between the bush and the frame of the bogie, with a stablising effect.
  • a connecting mechanism of the type defined at the beginning further comprises supplementary resilient means disposed in series with the rubber sleeves associated with the end of the push rod connected to the frame of the bogie and acting so as to increase the transverse elasticity of the said connection when the transverse forces applied to the bush exceed a predetermined threshold value.
  • two sleeves of elastomeric material are provided between the frame of the bogie and the corresponding end of the push rod, the sleeves being axially spaced, and the said supplementary resilient means.consist of a helical compression spring interposed coaxially between the two rubber sleeves, the ends of said spring reaction against respective abutments which can approach each other axially, and which bear against the two rubber sleeves.
  • the additional resilient means may comprise cup springs or their equivalent.
  • FIG. 1 there is indicated diagrammatically at 10 a part of the frame of a railway vehicle bogie, for example of a locomotive,and at 12 one part of a bush for railway axles connected to the frame 10 by a connecting rod or a longitudinal push rod 14.
  • the connecting rod 14 has at one end a tubular part 16 of small axial length which serves for connection to the bush 12 and at the opposite end, a tubular part 18 greater length for connection to the frame 10.
  • the tubular part 16 is traversed axially by a connecting pin 20 which has prismatic ends 20a engaged in corresponding holes 22 in the bush 12, and a central cylindrical part 24 connected to the tubular part 16 of the connecting rod 14 through a rubber sleeve 26.
  • the other tubular part 18 of the connecting rod 14 is traversed by a connecting pin 30 which has a central cylindrical part 32, two cylindrical end parts 34 of smaller diameter and two prismatic terminal parts 36 engaged in corresponding holes 38 in the frame 10.
  • each sleeve 40 including an inner metal ring 42, an inner ring44 of elastomeric material, an intermediate metal ring 46, an outerring48of elastomeric material and an outer metal ring 50.
  • the inner metal rings 42 are keyed to two bushes 52 adjacent the surfaces of the cylindrical end parts 34 of the pin 30,the bushes 52 having respective external annular stop flanges 54 at their adjacent axial ends.
  • the outer metal rings 50 of the two sleeves 40 are keyed to a bush 56 adjacent the inner wall of the tubular part 18 of the rod 14.
  • the central part 32 of the pin 30 is surrounded by a helical compression spring 58 the ends of which react against a pair of abutment rings 60 slidable axially along the bush 56.
  • Each abutment ring 60 hasan external annular axially projecting lip 62 against which the outer metal ring 50 of a respective sleeve 40 abuts, and a radially inwardly projecting flange 64 which cooperates with the annular flange 54 of the corresponding bush 52.
