摘要： A friction/elastomeric draft gear having a housing, a spring assembly arranged within the housing, and a friction clutch assembly having a wedge member and defining first sliding friction surface disposed at an angle θ relative to a longitudinal axis of the draft gear and a second friction surface disposed at an angle β relative to a longitudinal axis of the draft gear. The spring assembly is designed in combination with the angles θ and β of the first and second friction sliding surfaces relative to the longitudinal axis such that the draft gear consistently and repeatedly withstands between about 100 KJ and 130 KJ of energy imparted at less than three meganewtons over a range of travel of the wedge member in an inward axial direction relative to the draft gear housing not exceeding 120 mm.

摘要： 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.

摘要： A railcar draft gear housing formed from an austempered ductile iron casting having an original shape and including an open end, a closed end, and wall structure axially extending between the housing's ends. The wall structure of the housing defines an axial section between and spaced from the ends. The axial section of the wall structure is configured to withstand impact energy imparted to the housing in excess of 81,000 inch pounds while retaining and exhibiting substantially linear elasticity wherein the resultant ratio of stress to energy input remains substantially constant thereby allowing for flexible distortion of the housing in a manner promoting enhanced energy damping characteristics while allowing the casting to return to the original shape after the impact energy is released threrefrom.
