Problems solved by technology

The dynamics of the internal combustion engine are limited due to the large rotating mass, especially in combination with torsional vibration dampers, such as a split flywheel with a large flywheel mass, so that, for example, the shifting is prolonged during automatic gear changes

Embodiment Construction

[0018] The single FIGURE schematically shows the upper half of a drive train 1 arranged around an axis of rotation d with: a merely implied internal combustion engine 2 with a crankshaft 3 ; a torque transmission device 6 arranged on the crankshaft 3 and only Between the transmission input shaft 4 of the implied automatic transmission 5 there is a torsional vibration damper 7 and a wet-running friction clutch 8 . The torsional vibration damper 7 is designed as a dual-mass flywheel 9 with an input 11 connected to the crankshaft 3 and receiving the spring arrangement 10 as primary flywheel mass, and an output 14 connected to the The transition plate 13 is connected. The secondary flywheel mass of the dual-mass flywheel 9 forms a centrifugal force pendulum 15 and a friction clutch, and the centrifugal force pendulum is formed by a flange part 16 and a pendulum mass 17 .

[0019] The input part 11 and the output part 14 can be twisted relative to each other against the action of ...

Abstract

The invention relates to a drive train for a motor vehicle, comprising: an internal combustion engine, which has a crankshaft; a manual transmission, which is operated in an automated manner and which has a transmission input shaft and a transmission housing, which transmission housing forms a clutch bell housing together with the internal combustion engine; a torsionsal vibration damper, which is accommodated on the crankshaft by means of an input part; and a friction clutch, which is arranged after the torsional vibration damper, is connected to an output part of the torsional vibration damper, is accommodated in the clutch bell housing, is connected to the transmission input shaft in a rotationally locked manner, and is operated in an automated manner. In order to shorten the shifting times and thus the interruption times of a traction force of the automated manual transmission, the friction clutch is accommodated in a wet space sealed off from the torsional vibration damper and from the clutch bell housing by means of a cover and has an input-side outer plate carrier that accommodates input plates in a rotationally fixed manner and an output-side inner plate carrier that accommodates output plates layered in alternation with the input plates in a rotationally fixed manner, and a flange part is provided in the wet space, which flange part is connected to the output part in a rotationally locked manner, drives the outer plate carrier, and has a centrifugal force pendulum having pendulum masses arranged radially outside the outer plate carrier.

Description

technical field [0001] The invention relates to a drive train for a motor vehicle comprising: an internal combustion engine with a crankshaft; an automatically operated shift transmission with a transmission input shaft and a transmission housing forming a clutch housing together with the internal combustion engine; a torsional vibration damper on the crankshaft; and a self-operating friction clutch connected downstream of the torsional vibration damper, connected to the output of the torsional vibration damper, received in the clutch housing and rotationally locked with the transmission input shaft ground connection. Background technique [0002] A drive train with an automatically shifted transmission is known, for example, from DE 10316421 A1, in which the automatically operating friction clutch between the internal combustion engine and the transmission is designed as a dry-operating friction clutch. Due to the large rotational mass, especially in combination with a tor...
