Power transmitting system for four-wheel drive vehicle

A power transmitting system for a vehicle in which a laterally mounted front drive engine is provided, comprising:

• a transmission which transmits a driving force, coupled to said engine;
• a gear mechanism;
• a transmission shaft section to which the driving force is transmitted via said gear mechanism;
• and
• an output shaft provided in said gear mechanism, an axis line thereof being arranged to locate at least one of above or below a vehicle constituting members provided in a width direction of the vehicle, the output shaft being formed into a hollow shaft having an inside face formed into a spline hole,
• wherein an input shaft of said transmission shaft section is formed into a spline shaft, and said output shaft and said input shaft are slidably spline-fitted to each other.

A power transmitting system for a vehicle in which a laterally mounted front drive engine is provided, comprising:

• a differential gear unit;
• a transmission shaft section;
• and
• a gear mechanism provided in connection with said differential gear unit, which have a transaxle coupled to said engine and transmitting a power to said transmission shaft section via said gear mechanism so that the power is transmitted to a final reduction gear unit of rear wheels,
• wherein said gear mechanism comprises bevel gears and helical gears, and wherein an input shaft of said transmission shaft section is formed into a spline shaft, and said output shaft and said input shaft are slidably spline-fitted to each other.
