Claims

[Scope of utility model registration request]

A ring gear and a sun gear arranged concentrically,
A differential gear device is provided in an interaxle differential case driven by the output shaft of the transmission, and includes a ring gear and a pinion gear that rotationally drives a sun gear around an axis, and the ring gear is used as a final reduction gear for rear wheels. In the all-wheel drive system for a rear engine bus, the sun gear is connected to a final reduction gear for front wheels, the final reduction gear for rear wheels is attached to a cover of the final reduction gear for rear wheels and a cover of a differential gear device. A lubricating oil passage is provided to guide lubricating oil scooped up by a gear installed inside the cover of the differential gear device to a lubricating oil reservoir formed near one end of the cover of the differential gear device. an annular flow path formed between the inner peripheral surface of the interaxle differential case and the outer peripheral surface of the shaft portion of the sun gear and reaching the gear portion of the sun gear from the lubricating oil reservoir; A lubricating device for an all-wheel drive device in a rear engine bus, characterized in that a lubricating oil hole is provided that reaches a sliding surface with a pinion shaft that rotatably supports the pinion gear.
