CONTROL MECHANISM FOR A TRANSMISSION OF A FOUR-WHEEL DRIVE VEHICLE

摘要

A control mechanism for a transmission apparatus for a four-wheel drive Motor vehicle comprising an auxiliary change-speed transmission adapted to transmit power from the engine to a main transmission, a final reduction device for transmitting the output of the main transmission to the front axle and to the rear axle, a clutch connected to the final reduction device for transmitting the output of the main transmission for selectively connecting or disconnecting the transmitting of the output to either of the front or rear axle. An operation rod is longitudinally and slidably provided for swinging first and second guide plates. Each guide plate has a guide groove with which a part of a fork engages. By operating the operation rod, first and second guide plates are swung to cause forks to shift with engagement with the guide grooves. The guide grooves are so arranged as to establish two-wheel high speed range driving, four-wheel high speed range driving and four-wheel low speed range driving.
