Transfer device of four-wheel-drive vehicle

摘要

In a part-time (selective) four-wheel-drive vehicle, the engine driving power is selectively transmitted to the rear (or front) wheels by way of a transfer clutch which is operated by a hydraulic actuator acting through a rail and a sleeve of the dog clutch and being controllable by a changeover valve operated by a solenoid which is controlled by a four-wheel-drive switch manipulative by the driver.
