PURPOSE:To make it possible to change over a hour/two wheel drive changeover means between both operations in a passenger's compartment without a clutch being subjected to excessive shock and load, by engaging the clutch with a some delay from the coupling of transfer upon change-over of the change-over means. CONSTITUTION:One 7a of rear axles is splitted into parts 7a', 7a'' between which a remote controllable clutch 9 is disposed. A vacuum switch valve VSV2 is disposed in the intermediate section of a pipe line 12 connecting between an intake manifold 11 and the clutch 9, and a vacuum switch VSV1 is disposed in the intermediate section of a pipe line 13 connecting between the intake manifold 11 and a transfer 4. A delay circuit D is disposed between a four/two wheel drive change-over switch 14 and the valve VSV2. Due to the provision of the delay circuit D the valve VSV2 is turned into its opened condition with a some delay from the operation of the valve VSV1, and upon changeover the clutch 9 may be engaged with no shock. |
