Abstract:
A four-wheel drive vehicle includes a dog clutch that selectively interrupts transmission of a drive force to a propeller shaft, first and second multi-plate clutches that selectively interrupt transmission of the drive force from the propeller shaft to left and right rear wheels, first and second pistons that press the first and second multi-plate clutches, and a hydraulic circuit that supplies hydraulic oil to first and second cylinder chambers. During a transition to a four-wheel drive mode, torque transmitted through the first multi-plate clutch increases the speed of rotation of the propeller shaft so as to engage the dog clutch, and the second multi-plate clutch is kept from transmitting torque to the propeller shaft.
