Zusammenfassung:	There is represented friction/elastomeric draft gear having spring assembly 70 arranged within housing 16, and friction clutch assembly 40 having wedge member 50 and defining first sliding friction surface 49 disposed at an angle θ relative to lon¬gi¬tudinal axis of draft gear, and second friction sur¬face 59 disposed at an angle β relative thereto. Spring assembly is designed in combination with the angles θ and β of first and second friction sliding surfaces relative to longitudinal axis such, that the draft gear consistently and repeatedly with¬stands between about 100KJ and 130 KJ of energy imparted at less than three meganewtons over the range of travel of wedge member in inward axial direction relative to draft gear housing, not exce¬eding 120mm. 19 dependent
