Embodiment Construction

[0025] exist Figure 1 to Figure 6 In each of the variant embodiments of the planetary multi-stage transmission for vehicles according to the invention (for example as automatic transmission or automatic transmission) are shown by way of example, in these variant embodiments, the third clutch implemented as a clutch is shown Different positions of the shifting elements.

[0026] Independently of the corresponding variant embodiment, the multi-stage transmission comprises a only schematically indicated housing 11 with a first shaft 1 as drive element An and a second shaft as output element Ab arranged axis-parallel thereto. 2 and another seven axes 3, 4, 5, 6, 7, 8, 9. Furthermore, a first planetary gearset RS1 , a second planetary gearset RS2 and a third planetary gearset RS3 are provided, which are preferably designed as negative planetary gearsets. For shifting several gear stages, a first shifting element K1 embodied as a clutch, a second shifting element K2 embodied as a...

Abstract

The invention proposes a planetary multi-stage transmission with a housing (11) for a vehicle, wherein a first shaft (1) as a driving element (An) and a driven The second shaft (2) of the member (Ab), where three planetary gear sets (RS1, RS2, RS3) and further shafts (3, 4, 5, 6, 7, 8, 9) and six gear elements (K1, K2, K3, K4, B1, B2), through which multiple gear stages can be achieved by operating these shift elements, wherein mechanical elements (ST1, ST2) are provided for switching between the drive element (An) and The torque is transmitted between the driven member (Ab), in which the first shaft (1) as the driving member and the sun gear (SR3) of the third planetary gear set (RS3) and the second planetary gear set (RS2) The sun gear (SR2), connectable to the planetary gear carrier (PT3) of the third planetary gear set (RS3), and connectable or connectable to the sun gear (SR1) of the first planetary gear set (RS1), and wherein, as The second shaft (2) of the follower (Ab) is connected or connectable to the first machine element (ST1) and the second machine element (ST2).

Description

technical field [0001] The invention relates to a planetary structure multi-stage transmission for vehicles. Background technique [0002] A power shiftable multi-stage transmission is known, for example, from 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 shift the eight forward gears and one reverse gear, five shift eleme...
