Transfer gear-box

摘要

The present invention relates to a transfer gear-box having a casing, an input shaft, a rear output shaft, a front output shaft, and two planet gear sets,
the rear output shaft being arranged co-axially to the input shaft,the front output shaft being offset in relation to the input shaft,the two planet gear sets being arranged co-axially to the input shaft,the first planet gear set being a simple planet gear set and consisting of a ring gear, a sun wheel, a planet carrier, and several planet wheels, which are rotatably mounted to the planet carrier,the second planet gear set being a simple planet gear set and consisting of a ring gear, a sun wheel, a planet carrier, and several planet wheels, which are rotatably mounted to the planet carrier.
