Definitions

  • This invention relates to steering links for bogies and to wagons incorporating such bogies.
  • the invention consists in a variable length steering link assembly including an elongate link having a generally T-shaped head at each end and an anchor for each end, wherein each anchor defines an axially extending chamber for slidably receiving a respective head and a compression spring, wherein in one chamber the spring acts on the end face of its associated head and in the other chamber the spring acts on the back face of its associated head.
  • the first mentioned chamber arrangement allows for telescopic contraction along an axial direction
  • the second mentioned chamber allows for telescopic extension of the link assembly.
  • the link assembly is always acting to compress a spring.
  • the arrangement is particularly economic to manufacture and assemble, because the anchor portions and springs can be identical and only a single spring has to be manipulated in the assembly of each anchor.
  • the link may have a central element and two head elements, the head elements being identical and therefore requiring a small inventory of easy to manufacture parts.
  • the link assembly may include hard stops for limiting extension or contraction of the assembly. These conveniently can be provided by rigid cylinders circumjacent respective springs.
  • the invention consists in a container wagon having at least a pair of bogies having wheels of diameters of less than 600mm characterised in that each bogie has a steering link, extending from its frame to a wheel set, for each wheel set.
  • a steering link is a device which reactively responds to forces moving the wheel sets relative to the frame to control and limit that movement.
  • Each link may be extendable and may include a pair of compression springs, one of which is compressed on extension of the link and one of which is compressed on contraction of the link.
  • the or each link may be constituted by a steering link assembly as defined above.
  • a wagon for containers is generally indicated at 10. It includes a pair of bogies 11, having 577mm diameter wheels 12, and a deck 13 which is carried on side bearers 14 of the bogies 11.
  • the deck height is 730mm above the rail level.
  • the bogie 11 includes a frame 15, which is suspended on wheel sets 16, by respective suspensions 17.
  • the frame is cranked at 18 to allow for a low position of the side bearers 14.
  • Steering links 19 are provided to extend respective fixed points 20 on the frame 15 and the respective axle boxes of respective wheel sets 16.
  • Each steering link 19 can be extended and contracted in a controlled manner in response to longitudinal displacement of the associated wheel 12 so as to simultaneously allow a degree of movement, but in a controlled fashion.
  • This arrangement enables the disadvantages that arise from using the smaller wheels, i.e. wheels of less that 600mm diameter, whilst avoiding the significant cost of fully steerable or self-steerable wheel sets.
  • the steering link 19 comprises a central elongate link element 22 having T-shaped heads 23 fixed to its respective ends, and anchor portions 24, which telescopically house the heads 25 of the members 23.
  • each anchor member 24 comprises a ball joint 26 which is integrally connected to a first housing member 27, which can be joined with a second housing member 28, by means of bolts 29 to form a chamber 30 in which a head 25 is received.
  • Each chamber 30 also contains a compression spring 31 and a rigid cylinder 32 which is circumjacent the spring 31.
  • the compression spring 30 is mounted to act between the first housing member 27 and the end face 33 of the head 25, whereas at the left hand end the spring 31 is located to act between the second housing member 28 annular rear face 34 of the head 25.
  • the sleeves 32 provide "hard stops" for the respective heads 25 so as to limit the degree of longitudinal movement that can occur for the wheels 12, for example under heavy braking.
