Abstract
An actuation assembly for use in a drive unit assembly of a vehicle. The actuation assembly includes an actuator shaft that is connected to a shift shaft and a shift fork via a lever member. At least a portion of the lever member is connected to the shift shaft and at least a portion of the lever member is pivotably connected to said actuator shaft. An actuation mechanism drives the actuator shaft linearly to pivot the lever member which in turn rotates the shift shaft and the shift fork.
