Abstract: The disclosure relates to a clutch assembly for a manual transmission of a motor vehicle, having an axially running transmission input shaft which, by way of a clutch having a central release mechanism disposed on the transmission input shaft, is able to be coupled to a motor output shaft. The transmission input shaft has at least one ferromagnetic measuring portion. The magnetization of the ferromagnetic measuring portion is able to be influenced in a magnetoelastic manner by a torsion of the transmission input shaft. Portions of the central release mechanism surround the at least one measuring portion and has a sensor device which is specified for measuring a variable as a function of the magnetization of at least one measuring portion.

Abstract: A gear mechanism for motor vehicles includes a double clutch gear mechanism with two part gear mechanisms and a double clutch which transmits torque from the engine optionally to one of the two part gear mechanisms, with a central disk connected to a drive disk, two outer pressure application plates which are also connected to the drive disk and are moveable in the axial direction relative to the central disk, and friction disks arranged between the central disk and the pressure application plates, wherein the friction disks consist of two support carrier disks arranged parallel to each other and moveably in relation to each other, between which leaf-like spring segments are provided. To eliminate vibration problems which can occur on start-up from standstill, on load-change processes and during the gear change, the leaf-like spring segments have different spring characteristic curves with which a multistage spring characteristic is achieved.
