    摘要: A fast turn-off and fast turn-on circuit (10) providing at least one power source (12, 20), at least one switching device (14, 22), a coil (16), and at least a first voltage control device (18). The at least one switching device (14, 22) is connected to the at least one power source (12, 20) for selectively connecting the at least one power source (12, 20) to portions of the circuit (10). An electrical current from at least one power source (12, 20) charges the coil (16) and creates an electromagnetic field when the at least one switching device (14, 22) is in a closed position and connects the at least one power source (12, 20) with the coil (16). The first voltage control device (18) limits a voltage in the circuit (10) when the electromagnetic field decays.

    摘要: A shift fork restrictor operably disposed in a transfer case for the purpose of allowing the shift motor to transfer energy to the currently existing double wound spring, where the energy is stored until the shift motor sensor indicates that the motor is in the proper range location. When the motor is in the proper range location, the stored energy in the spring is released by the shift fork restrictor releasing the cam allowing for maximum torque and speed to be provided through the secondary rail, cam, and shift fork to complete the requested range shift. This configuration can be used to, among other things, select a high or low range in the transfer case, as well as couple the input and output shafts together, which have different gear ratios.
