ABSTRACT:
A power transmission system for a four-wheel drive vehicle has, for the front and rear wheels, a driving power transmitting system for transmitting the output of a transmission with a forward overrunning clutch and a reverse overrunning clutch. Either or both of the overrunning clutches are engaged with a sleeve of a selecting device. An outer race of each overrunning clutch has outer toothings on the periphery thereof and the sleeve has inner toothings. Each inner toothing of the selecting device has chamfers on both axial ends thereof, and each outer toothing has a chamfer on an end opposing the inner toothing. Opposed chamfers of the inner and outer toothings have an angle so that a component in a free rotational direction of the outer toothing is produced by the engagement of the chamfer of the inner toothing.
