Abstract
A railcar draft gear assembly including a housing, a spring sea, a spring and a friction clutch assembly in operable combination relative to each other within the housing. The spring includes a series of axially stacked elastomeric pads arranged between a closed end of the housing and the spring seat. An axially elongated guide rod is endwise passed through the spring seat and elastomeric pads for aligning the pads relative to a longitudinal axis of the draft gear assembly. The guide rod is operably inhibited from axial shifting movements during operation of the draft gear assembly. A related method for assembling the draft gear is also disclosed.
