Abstract
The present invention refers to an elastic supported mechanism consisting of an elastomer ring in which are arranged rigid intercalated rings adhering to the elastomer and capable in particular of being mounted in series with a helical spring, notably in a railroad bogie side suspension. The mechanism is characterized by the fact that it comprises, in the center of the bore (14) of the elastomer ring, a central plug (2) whose outer surface (24) is separated, in the absence of pressure, from the elastomer surface of the bore of the ring and is capable of progressively coming into contact with the aforesaid elastomer surface of the bore when the ring is subjected to an increasing horizontal pressure.
Claims16
An elastic supported mechanism comprising a hollow elastic ring of generally cylindrical cross section, a plurality of intercalated rigid rings within said elastic ring respectively disposed about the axis of said elastic ring, said intercalated rings being spaced from one another along the axis of said elastic ring in substantially parallel relationship with one another, a stop fixedly disposed within a central bore of said elastic ring and having an outer peripheral surface normally spaced from the inner periphery of said elastic ring, said outer peripheral surface of said stop and the inner periphery of said elastic ring being configured such that when said elastic ring is subjected to an increasing pressure perpendicular to said axis thereof, said outer peripheral surface of said stop and the inner periphery of said elastic ring come progressively into contact with each other, thereby progressively increasing the rigidity of said mechanism in the direction of said load.
An elastic supported mechanism comprising a substantially cylindrical elastic ring having a central bore, a pair of rigid brace members bonded to opposite axial end surfaces of said elastic ring, a plurality of rigid flat ring members disposed within said elastic ring respectively about a central axis thereof, said ring members being parallel to one another and spaced apart from one another along said axis, and stop means fixedly disposed within said central bore of said elastic ring and having an outer peripheral surface normally spaced from the inner periphery of said elastic ring in the absence of a load on said elastic ring in a direction perpendicular to said axis thereof, said outer peripheral surface of said stop means and the inner periphery of said elastic ring being configured such that when said elastic ring is subjected to a load in said perpendicular direction, said outer peripheral surface of said stop means and the inner periphery of said elastic ring come progressively into contact to increase the rigidity of said mechanism in said direction.
A support mechanism comprising, in combination, first and second capping plate means separated from one another along a first axis, spring means disposed intermediate said first and second capping plates and compressible therebetween along said first axis in response to a load along said axis, and elastic support means deformable along a second axis perpendicular to said first axis and mounted in a fixed position on said second capping plate means, said elastic support means including a substantially cylindrical elastic ring having a central bore and extending axially in the direction of said first axis, a pair of rigid brace means bonded to opposite axial end surfaces of said elastic ring, a plurality of flat rigid ring members disposed within said elastic ring respectively about the axis thereof, said ring members being spaced apart along the axis of said elastic ring and parallel to one another, and stop means fixedly disposed within said central bore of said elastic ring and having an outer peripheral surface normally spaced from the inner periphery of said elastic ring, said outer peripheral surface of said stop means and the inner periphery of said elastic ring being configured such that when a load in the direction of said second axis is applied to a one of said brace members opposite said second capping plate means, the inner periphery of said elastic ring comes progressively into contact with said outer peripheral surface of said stop means.
