1. An actuator system comprising:
a support;
a drive system connected to the support;
a shift fork operatively connected to the drive system and configured to move a distance defining a stroke length between a disengaged position and an engaged position of one or more gears of a transmission, the shift fork having a cam follower;
a cam assembly operatively connected with the drive system to move between a neutral position, and a shifted position, with a plurality of intermediate positions between the neutral position and shifted position, the shift fork being in the disengaged position when the cam assembly is in the neutral position, the cam assembly including:
a cam having an aperture defining an interior surface;
a hub housing disposed within the aperture of the cam and connected to the drive system; and
a biasing member disposed within the aperture and preloaded between an interior surface of the aperture of the cam and the hub housing;
wherein the cam moves relative to the hub housing with the biasing member compressing between the hub housing and interior surface of the cam when the cam assembly is rotated through the plurality of intermediate positions and the shift fork remains in the disengaged position due to an interference preventing the shift fork from completing the stroke length; and
wherein the cam moves relative to the hub housing with the biasing member expanding to push the cam against the shift fork such the shift fork moves through the stroke length from the disengaged position to the engaged position upon clearance of the interference;
wherein the biasing member is free from exerting force onto the shift fork when the shift fork is in the engaged position.
