Embodiment Construction

[0060] figure 1 A transmission according to a first embodiment of the invention is shown.

[0061] exist figure 1 Reference numeral 1 in the figure indicates a multi-speed transmission. The multi-speed transmission 1 has six shift elements in the form of three clutches K1 , K2 , K3 and three brakes B1 , B2 , B3 . By means of three clutches K1 , K2 , K3 , the drive side of the transmission 1 can be coupled or connected to the output side of the transmission for the transmission of forces and torques. To this end, the first clutch K1 , the second clutch K2 and the third clutch K3 are connected to the drive shaft ANW on the drive end. The first clutch K1 is additionally connected to the first shaft W1 such that when actuated it transmits forces and torques from the drive shaft ANW to the first shaft W1. The same applies correspondingly for the second clutch K2 and the third clutch K3. When the second clutch K2 is engaged, force is transmitted from the drive shaft ANW to the ...

Abstract

The invention relates to a transmission, in particular multi-stage transmission, for a motor vehicle, comprising a housing, a drive input shaft, a drive output shaft, at least four planetary gear sets and six shift elements in the form of at least three clutches and at least two brakes, the planetary gear sets each comprising a sun gear, at least one planet gear, a planet gear carrier and an internal gear, wherein the drive input shaft can be connected by means of the second clutch to the planet gear carrier of the first planetary gear set, and the planet gear carrier of the first planetary gear set can be connected to the second brake, and the drive input shaft can be connected by means of the third clutch to the first brake, and the drive input shaft can be connected by means of the third clutch to the sun gear of the first planetary gear set.

Description

technical field [0001] The invention relates to a transmission for a motor vehicle, in particular a multi-speed transmission, comprising a housing, a drive shaft, a driven shaft, at least four planetary gear sets and six shifting elements. The planetary gear sets each have a sun gear, at least one planet gear, a planet carrier and a ring gear, and the shift elements are in the form of at least three clutches and at least two brakes. Background technique [0002] Such a transmission is known, for example, from WO 2012 / 052284 A1. WO 2012 / 052284 A1 shows a multi-speed transmission with six forward gears and one reverse gear, comprising four planetary gear sets, seven rotatable shafts and five shifting elements, wherein the first planetary gear set The sun gear is connected to the sixth shaft, which can be coupled to the transmission housing via the first brake, and the planet carrier of the first planetary gear set is connected to the fifth shaft, which is connected to the sec...
