Embodiment Construction

[0054] figure 1 The transmission according to the first embodiment of the present invention is shown.

[0055] 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 aid of clutches K1, K2, K3, K4, the drive side can be coupled or connected with the output side of the transmission 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 drive shaft ANW to the second shaft W2, and w...

Abstract

Transmission, in particular multi-step transmission, for a motor vehicle, comprising a housing, a drive shaft, an output shaft, at least four planetary gear sets, wherein the planetary gear sets in each case comprise a sun gear, a planet, a planetary carrier and an internal gear, and a plurality of shifting elements in the form of at least four clutches and at least two brakes, wherein the drive shaft can be connected via the second clutch to the planetary carrier of the third planetary gear set and the planetary carrier of the fourth planetary gear set, wherein the first brake is connected to the internal gear of the first planetary gear set and to the planetary carrier of the second planetary gear set, wherein the second brake is connected to the sun gear of the first planetary gear set, and wherein the planetary carrier of the first planetary gear set is connected to the sun gear of the fourth 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 respectively include a sun gear, a planet gear, and a planet carrier And the 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 shaf...
