  • Stabilized bearing for bogies
    Patent number: 4443045
    Abstract: A swivel bearing is provided for a bogie which comprises a support mounted on a first race ring, a friction lining and a rolling element attached to the support for providing a braking position to the friction lining. A second race ring engages the first race ring through rolling elements. A counter friction lining support element is solidly mounted on the second race ring and supports a counter friction lining for engaging the friction lining. A cam element is attached to the second race ring suitably for engaging the roller to provide for a positioning of the friction lining versus the counter friction lining over a desired angle. The counter friction lining support element is preferably a clamp spring of suitable tension for limiting the total braking force on the bogie rotation.
