A friction clutch type draft gear assembly includes a housing having an open front end and a closed rear end forming a ledge for enabling a longer buff and draft travel while fitting into a 24.625 inch draft gear pocket. A friction clutch mechanism includes a pair of outer stationary plate members, a pair of movable plate members, a pair of inner stationary plate members having an inner surface which is tapered at an angle of approximately 4.5°, a pair of wedge shoe members having an upper surface which is tapered from a point disposed inwardly from the tapered outer surface inwardly toward and at an acute angle relative to a longitudinal axis of the friction clutch mechanism, and a center wedge member which includes a pair of correspondingly tapered surfaces frictionally engageable with the upper tapered surface of a respective one of the pair of wedge shoe members. The tapered upper surface of the pair of wedge shoe members is tapered at an angle of approximately 49.0°-50.0°. The pair of tapered surfaces of the center wedge is tapered at an angle of about 49.5°. |
