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.
Claims23
An actuation assembly, comprising:
- an actuator shaft;
- a shift shaft;
- a shift fork connected to at least a portion of said shift shaft;
- a lever member connected to at least a portion of said shift shaft and pivotably connected to at least a portion of said actuator shaft;
- one or more first stopper members and/or one or more second stopper members;
- one or more sleeve members disposed around at least a portion of said one or more first stopper members and/or said one or more second stopper members;
- wherein said one or more sleeve members have a thickness needed to limit movement of said lever member and allow a sliding collar to selectively transition between a first position, a second position and/or a third position;
- and
- an actuation mechanism selectively transitioning said sliding collar between said first position, said second position, and/or said third position.

An actuator assembly, comprising:
- an actuator shaft having a plurality of teeth circumferentially extending along at least a portion of an outer surface thereof;
- a shift shaft;
- a shift fork connected to at least a portion of said shift shaft;
- a gear member having a plurality of teeth;
- wherein at least a portion of said plurality of teeth of said gear member are complementary to and meshingly engaged with at least a portion of said plurality of teeth on said outer surface of said actuator shaft;
- an actuation mechanism;
- and
- wherein said actuation mechanism is operably configured to selectively rotate said actuator shaft as needed to rotate said gear member which in turn rotates said shift shaft and said shift fork.
