Embodiment Construction

[0050] figure 1 A transmission according to a first embodiment of the invention is shown.

[0051] exist figure 1 In , reference numeral 1 denotes a multi-stage transmission. The multi-stage transmission 1 has six power shift shifting elements in the form of four clutches K1 , K2 , K3 , K4 and two brakes B1 , B2 . With the aid of the four clutches K1 , K2 , K3 , K4 , the drive side and the output side of the transmission 1 can be coupled or connected for power and torque transmission. For this purpose, the first clutch K1 , the second clutch K2 and the third clutch K3 are connected on the drive side to the drive shaft ANW. The first clutch K1 is also connected to the first shaft W1, so that when actuated it transmits forces and torques from the drive shaft ANW to the first shaft W1. The same applies for the second clutch K2 and the third clutch K3 . When the second clutch K2 is closed, force is transmitted from the drive shaft ANW to the second shaft W2; when the third ...

Abstract

The invention relates to a transmission, in particular multi-clutch transmission, for a motor vehicle, comprising the elements of a driveshaft, a plurality of planetary gear sets, wherein one planetary gear set comprises the planetary elements of a sun gear, one or more planetary gears, a web and a ring gear, N shifting elements, comprising a plurality of clutches, wherein N is an integer greater than four, and an output shaft, wherein the driveshaft can be connected to the output shaft by means of at least one of the N shifting elements in order to form a plurality of gear stages by means of at least one of the planetary gear mechanisms, wherein the N shifting elements comprise at least M brakes and N‑M clutches, wherein M is an integer greater than or equal to one, and wherein at least (N‑M) / 2 clutches interact with the driveshaft and / or the output shaft.

Description

technical field [0001] The present invention relates to a transmission for a motor vehicle, in particular a multi-clutch transmission, comprising the following elements: a drive shaft, a plurality of planetary gear sets, N switching elements and a driven shaft, wherein the planetary gear sets comprise planetary Gear set elements—a sun gear, one or more planetary gears, a planet carrier, and a ring gear, the N shifting elements including a plurality of clutches, wherein N is an integer greater than 4, by means of the N shifting elements At least one shifting element, the drive shaft and the driven shaft can be connected by means of at least one planetary gear of the plurality of planetary gears in order to realize different gears. Background technique [0002] Such a transmission is known, for example, from WO 2012 / 052284 A1. A multi-stage transmission with six forward gears and one reverse gear is disclosed in WO2012 / 052284A1, the multi-stage transmission includes four plan...
