Abstract

PURPOSE:To reduce speed silently while to reduce projection into cabin, by arranging center def and front def of four-wheel-drive vehicle equipped with a lateral engine coaxially then driving the center def through a chain. CONSTITUTION:Driving force of engine is transmitted through a clutch 5 to the input shaft 6 of transmission 3 then speed changed properly and outputted from a drive sprocket 25 of output shaft 9 through a chain 8 to a transmission sprocket 29 of center def 7. Said driving force is transmitted to the short shaft 28 at the center def 7, then distributed to the left and right through gearing of bevel gears 32-35 to drive the casing 38 of front def 10 and bevel gear 11. The center def 7 will function as a differential device to absorb differential rotation speed between bevel gears 34 and 35. In the front def 10, driving force is also distributed to the left and right to drive the front wheel. On the other hand, driving force will drive propeller and rear def through gearing of bevel gears 11, 12.
