Abstract
PURPOSE: To automatically change four-wheel drive and two-wheel drive for each other depending on the loading condition of the surface of the ground, by installing a clutch between a front and a rear shafts.
CONSTITUTION: When near wheels 5, 5 slip in mud during rear-wheel drive, a one- way clutch 12 is automatically engaged because of the speed fall of a rear axle 11 due to the slippage to run front wheels 9, 9. Therefore, a tractive force can be obtained despite the slippage of the rear wheels 5, 5. When the rear wheels 5, 5 are moved out of the mud by the four-wheel drive not to slip, the revolution speed V2 of the rear axle 11 rises to automatically disengage the one-way clutch 12 to resume rear-wheel drive. When the front wheels 9, 9 are overloaded, a slip clutch 13 is automatically disengaged not to overwork the transmission system.
