Patent ID: 8905890

Claim:
A range-change transmission ( 1 ) of a motor vehicle, the range-change transmission comprising: a multi-stage main transmission (HG), a splitter group (GV) of gears connected upstream from the main transmission, and a range group (GP) of gears connected downstream from the main transmission, the main transmission (HG) being of a planetary design and comprising an input-side simple planetary gearset (PS 2 ) and an output-side simple planetary gearset (PS 3 ) arranged axially adjacent to one another such that the input-side simple planetary gearset (PS 2 ) being arranged on an input side of the main transmission and the output-side simple planetary gearset (PS 3 ) being arranged on an output side of the main transmission, each of the input-side and the output-side simple planetary gearsets having a respective sun gear ( 10 , 15 ), a respective ring gear ( 13 , 18 ), and a respective planetary carrier ( 11 , 16 ) that supports a plurality of gearwheels ( 12 , 17 ), the ring gear ( 13 ) of the input-side simple planetary gearset (PS 2 ) being connected, in a rotationally fixed manner, to an input shaft ( 9 ) of the main transmission (HG), the planetary carrier ( 11 ) of the input-side simple planetary gearset (PS 2 ) being connected, in a rotationally fixed manner via an intermediate shaft ( 14 ), to the sun gear ( 15 ) of the output-side simple planetary gearset (PS 3 ), the sun gear ( 10 ) of the input-side simple planetary gearset (PS 2 ) being either selectively lockable, via a dual shifting element (C 2 ) that is arranged close to the splitter group, to a housing or connected, in a rotationally fixed manner, to the intermediate shaft ( 14 ), the planetary carrier ( 16 ) of the output-side planetary gearset (PS 3 ) being either selectively lockable, via two single shifting elements (CRa, Crb), to the housing or connected, in a rotationally fixed manner, to an output shaft ( 19 ) of the main transmission (HG), and the ring gear ( 18 ) of the output-side planetary gearset (PS 3 ) being either selectively lockable, via a dual shifting element (C 3 ) arranged farther away from the splitter group, to the housing or connected, in a rotationally fixed manner, to the output shaft ( 19 ) of the main transmission (HG).
