ABSTRACT:
A transfer case for a part-time four wheel drive vehicle includes a planetary gear speed reduction assembly driven by the transfer case input shaft for providing high and low speed range outputs. The planetary gear assembly is disposed between and is selectively engaged by primary and secondary clutch collars, the primary clutch driving the rear (primary) output shaft in either the high or low speed ranges. The secondary clutch drives the front (secondary) output shaft through a chain drive in the low range. The clutch collars are controlled by a single (common) clutch operator. An electromagnetic clutch assembly driven by the input shaft selectively drives the front output shaft chain drive. The electromagnetic clutch functions both as a synchronizer and torque delivery device. The transfer case may be combined with a control which facilitates direct selection of vehicle drive mode.
