Abstract
Fail-safe operation is insured by forming a camming surface on an axially extending camming element (19), axially and rotatably secured to the take-off shaft (2), the camming surface being in engagement with a camming projection (18, 36) formed on the piston (10) which is in driving engagement with one of the cone disks (6) on the take-up shaft, and rotatably coupled to the cone disk, the cone disk, normally, being hydraulically positioned with respect to an opposing cone disk (5) of a cone pair; upon failure of hydraulic pressure, relative circumferential displacement of the cone disk (6) and hence of the piston, will cause axial movement of the piston (10) and hence transfer of axial movement to the cone disk (6) to raise a transmission belt (7) to operate at the largest circumference of the cone transmission, thus permitting limp-home operation of a motor vehicle equipped with the transmission at slow speed, but without loss of driving torque.
