A motor vehicle transmission having a housing, input and output shafts, shifting elements, a first planetary gearset having sun, ring and planet gears and a carrier and a second planetary gearset having planet gears and carriers that are rigidly coupled. The carriers of the first and the second gearsets are fixed, respectively, to the output and input shafts. A sun gear of the second gearset can be connected by a first shifting element to the housing and by a second shifting element to the input shaft. The ring gear of the first gearset can be connected by a third shifting element to the housing and by a fourth shifting element to the carrier of the first planetary gearset. The sun gear of the first gearset and ring gear of the second gearset are rigidly coupled, and the shifting elements are arranged in the housing and are accessible from the outside. |

1. A transmission (1, 10) for a motor vehicle, the transmission (1, 10) comprising:
a housing (G), a drive input shaft (ANW), a drive output shaft (AW), at least first and second planetary gearsets (PG1, PG4), the first planetary gearset (PG4) comprising a sun gear (104), at least one planetary gearwheel (114), a planetary carrier (124) and a ring gear (134), as well as a plurality of shifting elements (A to F, H, J, K, L, V, R, X, Y), and the second planetary gearset (PG1) comprising at least two planetary gearwheels (111.1, 111.2) and two planetary carriers (121.1, 121.2) on which the respective planetary gearwheels (111.1, 111.2) are mounted to rotate, the two carriers (121.1, 121.2) of the second planetary gearset (PG1) being connected, in a rotationally fixed manner, to one another and to the drive input shaft (ANW), the carrier (124) of the first planetary gearset (PG4) being connected, in a rotationally fixed manner, to the drive output shaft (AW), a sun gear (101) of the second planetary gearset (PG1) being connectable, by at least one first shifting element (K1, B), to the housing (G) and the sun gear (101) of the second planetary gearset (PG1) being connectable, by at least one second shifting element (A), to the drive input shaft (ANW), the ring gear (134) of the first planetary gearset (PG4) being connectable, by a third shifting element (E), to the housing (G), and, by a fourth shifting element (F), to the carrier (124) of the first planetary gearset (PG4), the sun gear (104) of the first planetary gearset (PG4) and a ring gear (131) of the second planetary gearset (PG1) being connected, in a rotationally fixed manner, to one another, and all of the shifting elements (A, B, E, F, K1) being arranged in the housing (G) and being accessible from an outside. |
