Abstract
A railway freight car constant contact side bearing positionable between a railway vehicle body and a wheeled truck supporting said railway freight car body with a housing or cage and a cap on such cage to engage the wear plate on the car body. The cage houses a plurality of springs having at least one metallic spring and at least one elastomer spring; such springs combine to support and dampen the forces of said vehicle body.
Claims25
A railway freight car constant contact side bearing as bearing between a railway vehicle body and a wheeled truck supporting said railway freight car body, comprising:
- a housing;
- a bearing cap;
- a plurality of springs disposed within said housing to apply a pressure to said cap;
- and
- said plurality of springs comprises at least one metallic spring and at least one elastomer spring.
A constant contact side bearing for a railway vehicle comprising:
- a housing;
- a cap;
- at least one elastomer spring within said housing;
- said spring having a generally cylindrical shape having a top surface in contact with said cap and a bottom surface in contact with said housing;
- and
- an outer surface having a tapered portion.
A method for controlled railway vehicle dynamics between a vehicle body and a railway truck within a constant contact side bearing comprising:
- supporting a vertical load with a metallic spring constant;
- and
- providing vertical dampening compression of an elastomer spring having hysteresis.
