Abstract
A power distributing device for four-wheel-drive vehicle including an input shaft, a first output shaft for transmitting power to rear wheels, a second output shaft for transmitting power to front wheels, a plane planetary gear set, a power train changing means and a synchronizing means. The plane planetary gear set includes a sun gear having a hollow shaft, a ring gear connected with the first output shaft, a planet carrier drivably connected with the input shaft, and planet gears carried by the planet carrier and engaged with the sun gear and the ring gear. The power train changing means includes a sliding sleeve and a sliding tube slidably mounted on the hollow shaft, engaged movably with the hollow shaft only in its axial direction, the sliding sleeve being selectively movable to engage either with a stationary portion of the device in a rear-wheel-drive condition or with the sun gear in a direct four-wheel-drive condition and a power distributing four-wheel-drive condition, the sliding tube being selectively movable to engage with the planet carrier in the direct four-wheel-drive condition. The synchronizing means is provided to inhibit nonsynchronous engagement of the sun gear with the stationary portion or the second output shaft.
