Abstract
A modular base side bearing assembly has a cage with upstanding side walls defining a bearing cavity and a central bottom opening to receive a modular base on which a bearing element supported on a central base portion thereof. The modular base has externally visible tabs identifying a force level corresponding to the modular base, in which the thickness of the central base portion corresponds such force level. The modular bases are interchangeable with modular bases having central base portions of differing thickness, or zero-thickness, such that the same cage, bearing element, and wear cap can be used with different modular bases to provide different force levels. The modular base is movable vertically relative to the cage to accommodate uneven mounting surfaces.
Claims34
A modular base and cage for a rail vehicle side bearing assembly, the modular base and cage comprising:
- a. a bearing element supporting a weight of a rail car and providing a force level to the rail car for resistance of rail car swivel;
- b. a cage having upstanding side walls, said cage defining a bearing cavity for receiving said bearing element, said cage having an open bottom;
- and
- c. a modular base receivable in said open bottom of said cage, said modular base forming the bottom surface of said bearing cavity for supporting said bearing element.
A modular base and cage for a rail vehicle side bearing assembly, the modular base and cage comprising:
- a. a cage having upstanding side walls, said cage defining a bearing cavity for receiving a bearing element, said cage having an open bottom;
- and
- b. a modular base receivable in said open bottom of said cage, said modular base forming the bottom surface of said bearing cavity for supporting said bearing element,
- wherein said central opening in said modular base defines side walls, said side walls centrally locating said bearing element when disposed in said bearing cavity.
A rail vehicle side bearing assembly comprising:
- a. a bearing element supporting a weight of a rail car and providing a force level to the rail car for resistance of rail car swivel;
- b. a cage having upstanding side walls, said cage defining a bearing cavity for receiving said bearing element, said cage having an open bottom;
- c. a modular base receivable in said open bottom of said cage, said modular base being a separate element from said cage and defining a bottom surface of said bearing cavity for supporting said bearing element.
A rail vehicle side bearing assembly comprising:
- a. a cage having upstanding side walls, said cage defining a bearing cavity for receiving a bearing element, said cage having an open bottom;
- b. a modular base receivable in said open bottom, said modular base defining a bottom surface of said bearing cavity for supporting said bearing element;
- and
- c. a bearing element disposed in said bearing cavity,
- wherein said opening in said modular base defines side walls, said side walls centrally locating said bearing element when disposed in said bearing cavity.
