DEVICE FOR CONTROLLING STIFFNESS AND DAMPING OF LOCOMOTIVE CARBODIES

摘要

A device for damping vibrations between a pair of sub-structural components of a carbody in a locomotive is disclosed. The sub-structural components are supported on a single undercarriage frame. The device includes a first support bracket affixed to a first sub-structural component, and a second support bracket that is interleaved with the first support bracket and affixed to a second sub-structural component. The device further includes a first stiffening element and a second stiffening element that are disposed on the first support bracket and in opposing relation to each other. The device further includes a reciprocating member that is rigidly connected to the second support bracket. The reciprocating member is movable between the first stiffening element and the second stiffening element to abut against one of the first stiffening element and the second stiffening element in response to a relative movement between the pair of sub-structural components of the carbody.
