ANTI-FRICTION CAM-OPERATED FRICTION DISK CLUTCH

摘要

A vehicle steering column can be frictionally locked in selected positions of adjustment by a cam-operated friction disk clamping mechanism. The cam operator includes a rotary shaft having an anti-friction thrust bearing on one end and an anti-friction cam mechanism on the other end. Anti-friction elements in the bearing and cam mechanism enable the shaft to be easily operated, while permitting the friction disks to have a strong clamping action.
