Embodiment Construction

[0047] figure 1 The transmission according to the first embodiment of the present invention is shown.

[0048] in figure 1 Here, reference numeral 1 denotes a multi-speed transmission. The multi-speed transmission 1 includes six switching elements in the form of four clutches K1, K2, K3, K4 and two brakes B1, B2. With the help of four clutches K1, K2, K3, K4, the drive side can be coupled or connected to the output side of the transmission through a shaft and / or planetary gear set to transmit force and torque. 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 driver side. The first clutch K1 is also connected with the first shaft W1 so that the first clutch K1 transmits force and torque from the drive shaft ANW to the first shaft W1 when being operated. The same situation applies to the second clutch K2 and the third clutch K3. When the second clutch K2 is closed, force and torque are transmitted from 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 multiple shift elements in the form of at least four 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 third clutch to the first brake and to the sun gear of the first planetary gear set and to the sun gear of the second planetary gear set, and wherein the internal gear of the first planetary gear set is connected to the planet gear carrier of the fourth planetary gear set, and wherein the planet gear carrier of the fourth planetary gear set can be connected by means of the fourth clutch to the drive output shaft, and wherein the sun gear of the fourth planetary gear set is connected to the housing, and wherein the second brake is connected to the planet gear carrier of the first planetary gear set.

Description

Technical field [0001] The invention relates to a transmission for a motor vehicle, in particular a multi-stage transmission, which includes a housing, a drive shaft, an output shaft, and at least four planetary gear sets. The planetary gear sets each include a sun gear and at least one planetary gear , A planet carrier and a ring gear, the transmission also includes a plurality of switching elements in the form of at least four clutches and at least two brakes. Background technique [0002] Such a transmission is known from WO2012 / 052284A1, for example. WO2012 / 052284A1 shows a multi-speed transmission with six forward gears and one reverse gear. The transmission includes four planetary gear sets, seven rotatable shafts and five switching elements. The first planetary gear set The sun gear is connected to the sixth shaft, the sixth shaft can be connected to the transmission housing via the first brake, the planet carrier of the first planetary gear set is connected to the fifth ...
