Abstract
The present invention includes shift mechanisms, lock assemblies and methods of adjusting a gear ratio of a transmission. According to one aspect of the invention, a shift mechanism configured to adjust a transmission includes a central axle defining a central axis; a drive member configured to rotate about the central axle responsive to an application of a driving force to the drive member; and a mount assembly comprising a mount support and an eccentric mount, the mount support being provided about the central axle and the eccentric mount defining an eccentric axis, the eccentric mount being movably coupled with the mount support to provide radial adjustment of the eccentric axis relative to the central axis and wherein resultant forces are generated responsive to the eccentric axis being spaced from the central axis, and the mount assembly being configured to utilize at least one resultant force to assist with movement of the eccentric mount with respect to the mount support.
