な四輪駆動車。 The power transmitted from the automatic transmission is always transmitted to one side of the front and rear wheels, and when a part of the hydraulic pressure for the transmission is applied by operating the switching lever, the power is activated and power is also transmitted to the other side of the front and rear wheels. 2 to communicate
A clutch mechanism capable of intermittent power transmission between at least one side gear of a wheel-to-four-wheel switching transfer and a differential that is a non-drive side during two-wheel drive and the wheel side, and a clutch mechanism that controls the operation of the clutch mechanism. A four-wheel drive vehicle capable of switching between two-wheel and four-wheel drive, which is equipped with a control mechanism for controlling the vehicle, and enters a four-wheel drive state by switching the transfer to the four-wheel drive side and connecting the clutch mechanism, The control mechanism is operated by operating the switching lever so that the switching lever
a first detection means for detecting that the transfer has been switched to the four-wheel drive side; and a second detection means that is operated by hydraulic pressure applied to the transfer and detects that the transfer has been switched to the four-wheel drive side. a driving means which is actuated by the detection operation of the second detection means to actuate the clutch mechanism to the connecting side; A four-wheel drive vehicle capable of switching between two-wheel drive and four-wheel drive, characterized in that it is configured to include compensation means for maintaining the operating state of the drive means on the connection side.
