Abstract

The invention relates to a multi-stage planetary transmission for a vehicle, comprising a housing (9), a first shaft (1) being provided as the drive (An) and a second shaft (2), arranged axially parallel thereto, as the output (Ab). Three planetary gear sets (RS1, RS2, RS3) and additional shafts (3, 4, 5, 6, 7, 8, 9) as well as six shift elements (K1, K2, K3, K4, B1, B2) are provided the actuation of which allows for a plurality of speeds, and machine elements (ST1, ST2) are provided for torque transmission between the drive (An) and the output (Ab). The first shaft (1) as the drive (An) can be connected to the ring gear (HR3) of the third planetary gear set (RS3), to the sun gear (SR1) of the first planetary gear set (RS1), to the sun gear (SR3) of the third planetary gear set (RS3), to the planet carrier (PT1) of the first planetary gear set (RS1) and to the first machine element (ST1), and the second shaft (2) as the output (Ab) is or can be connected to the first machine element (ST1) and to the second machine element (ST2).

Description

technical field [0001] The invention relates to a planetary multi-stage transmission for a vehicle according to the type defined in detail in the preamble of claim 1 . Background technique [0002] A power-shiftable multi-stage transmission is known, for example, from document DE 10 2007 014 150 A1. In a multi-stage transmission, the drive shaft is fixedly connected to the first shaft of the first shaft train via a torsional vibration damper. Furthermore, a second shaft system arranged parallel thereto includes a driven shaft called the second shaft. The two shaft systems are connected to each other via three spur gear stages. The three-shaft first planetary gear stage is located on the first shaft train. The second planetary gear stage and the third planetary gear stage are located on the second shaft train. The multi-stage transmission thus comprises ten shafts, which are connected to one another via three spur gear stages and three planetary gear stages. In order to ...
