摘要： A constant contact side bearing assembly for a railcar including a housing with wall structure defining a central axis for the side bearing assembly and a multipiece cap. The cap is arranged in operable combination with the housing and includes a movable first member or spring seat and a movable second member or top cap carried by the first member. A spring resiliently urges the cap members toward railcar body structure. The cap members define cooperating angled surfaces therebetween for urging wall structure on the first member and wall structure on the second member into frictional engagement with the wall structure on the housing in response to a vertical load acting on the friction contacting surface on the cap. At least the top cap is structured to establish a coefficient of friction ranging between about 0.4 and about 0.9 with the railcar during operation of the side bearing assembly.

摘要： A railroad car side bearing including a cage, a cap, a lock out insert configured to be removably connected to the cage, and an elastomer element configured to mate with the lock out insert. The lock out insert includes a key that is dimensioned based on a diameter of an interior channel of the elastomer element. Different lock out inserts with different dimensioned keys for different elastomer elements enable a common cage and a common cap to be used with different elastomer elements with different interior channel dimensions, thus reducing the need to have different cages.

摘要： A constant contact side bearing assembly configured for insertion into a walled receptacle provided on an upper surface of a railcar bolster. The side bearing assembly includes a housing assembly including a base and cap receivable within the open top walled receptacle on the bolster. The base has laterally spaced sides and longitudinally spaced ends. The cap is guided for movements relative to the base and has a generally flat railcar body engaging portion along with structure which combines with the sides and ends on the base to define an internal void for the side bearing assembly. A longitudinally elongated and generally rectangularly-shaped elastomeric compression spring is arranged in the internal void within the side bearing assembly for absorbing, dissipating, and returning energy imparted to the side bearing assembly during a work cycle. During a side bearing assembly work cycle, the spring is configured to deform in a predetermined manner and such that, upon maximum spring deformation, the spring maintains an operable relationship relative to the housing assembly of the side bearing assembly.

摘要： A side bearing for a railway car having a pair of spaced elongated resilient elastomeric elements which bias the elements of the side bearing in operative position and which elements preferably have uppermost separate members which are effective for generating increased frictional dissipation of energy over the frictional energy dissipation available with an elastomeric element only and for providing, in cooperation with the elastomeric elements, improved bearing performance through the deformation of the elastomeric elements under initial loading and under operating loads.

摘要： An element for supporting the suspension-springs of railway wagons including a bottom plate, an intermediate plate and a parallel adjacent supporting plate provided with the interposition of first and second elastic rings which are connected to the plates at their respective contacting surfaces. The second elastic ring has a greater rigidity compared to that of the first elastic ring. The greater rigidity is obtained by forming the second ring to have a lesser height (L") than that (L') of the first ring, or by use of an elastomeric material that is more rigid than the material which is used for forming the first ring.
