Preloaded brake disc

摘要

A disc brake system for a shuttle orbiter including an annular disc element (10) having internal radially directed and angularly spaced relief slots (12) and trapezoidial shaped carbon pad members (15) disposed circumferentially around the disc element. T Clips (19, 19') snugly engage the outer ends of the pad members and are attached to rivet heads (34, 35) and (34+40, 35') and have guide members (51, 51') slidably received in guide grooves (50, 50') in a spring housing (20). Springs (61) provide a force tending to move the T Clips toward the center of the disc where the magnitude of the force can be adjusted by a screw (65).
