Document Type and Number:
Japanese Patent JPH07109222
Kind Code:
B2
Abstract:
To the end of eliminating the problems arising from substantially rigid connection between a front wheel set and a rear wheel set in a four-wheel drive vehicle, there is provided a power transmission system in which a speed-dependent power transmission device is provided between the front wheel set and the rear wheel set so that both the wheel sets are substantially rigidly connected to each other in a low speed range and rotational power is transmitted only from the front wheel set to the rear wheel set in a high speed range. The power transmission device of this kind can be conveniently formed by a pair of one-way clutch elements which are connected between an input member and an output member in a mutually parallel relationship; one of the one-way clutch elements transmitting power from the input member to the output member in both the high and the low speed range while the other one-way clutch element transmits power only from the output member to the input member in the low speed range but does not transmit power in either direction in the high speed range. This speed-dependency can be accomplished by using one-way clutch sprag elements each having a gravitational center offset from its center of rolling motion for wedging between the input member and the output member.
