Abstract: A transfer case with an actuator for operating a two-speed transmission (i.e., range mechanism) and a clutch (i.e., mode mechanism). The actuator employs a motor-driven cam structure that coordinates the movement of a first fork, which is associated with the range mechanism, and a second fork that is associated with the mode mechanism. A resilient coupling is employed to provide compliance between the motor and the cam structure in the event that tooth-on-tooth contact inhibits the range mechanism from changing from a high-range mode and a low range mode. Compliance is provided between the cam structure and the second fork in the event that tooth-on-tooth contact inhibits the mode mechanism from changing from a 2WD mode to a 4WD mode. A sensor system identifies the placement of the first and second forks in various positions and responsively generates associated sensor signals.

Abstract: A chain drive system having chain links, guide links disposed on opposite lateral sides of the chain links, and pivot pins that extend through the chain links and are fixedly coupled to the guide links. Mating anti-rotation features are employed between each pivot pin and a corresponding one of the guide links to resist rotation between the pivot pin and the guide link.

Abstract: A transfer case with an actuator for operating a two-speed transmission (i.e., range mechanism) and a clutch (i.e., mode mechanism). The actuator employs a motor-driven cam structure that coordinates the movement of a first fork, which is associated with the range mechanism, and a second fork that is associated with the mode mechanism. A resilient coupling is employed to provide compliance between the motor and the cam structure in the event that tooth-on-tooth contact inhibits the range mechanism from changing from a high-range mode and a low range mode or tooth-on-tooth contact inhibits the mode mechanism from changing between a two-wheel drive mode and a four-wheel drive mode. A sensor target and sensor are employed to identify the rotational positioning of the cam structure placement, which is indicative of the modes in which the transmission and the clutch are operating.
