ABSTRACT:
The infinitely variable cone disk-wrapping vee belt drive comprises a pair of coaxial cone disks defining between them a vee-shaped groove and comprising an axially fixed, first cone disk and a second cone disk, which is axially displaceable relative to said first cone disk. A vee belt is trained around said first and second cone disks in said vee-shaped groove. First spring means urge said second cone disk axially toward said first cone disk. Locking means are provided, which are non-rotatably connected to one of said cone disks and movable to a locking position, in which said locking means hold said second cone disk against an axial displacement. Second spring means are provided, which urge said locking means to said locking position. Said locking means are arranged to unlock said second cone disk in response to a centrifugal force acting on said locking means and overcoming the force of said second spring means.
