Embodiment Construction

[0020] figure 1 The upper part of the torque transmission device 1 arranged around the axis of rotation d is shown schematically. The torque transmission device 1 is preferably arranged in a drive train of a motor vehicle between an internal combustion engine with a crankshaft and a transmission with torsional vibrations and a transmission input shaft.

[0021] The torque transmission device 1 provides the function of torsional vibration decoupling of the rotating internal combustion engine and the starting element. A dual-mass flywheel 2 and a hydrodynamic torque converter 3 are provided for this purpose.

[0022] The torque converter 3 includes a housing 4 with a pump wheel 5 , a turbine wheel 6 and a guide wheel 7 connected to the transmission housing via a freewheel (not shown). In order to bridge the lossy fluid torque transmission via the pump wheel 5 to the turbine wheel 6 , the wheel wheel 6 has a radially widening annular flange 8 on the radially outer side, while ...

Abstract

The invention relates to a torque-transmiting device (1) comprising a dual-mass flywheel (2) with an input part (11) arranged such that it can rotate about an axis of rotation (d), an output part (26)arranged such that it can rotate about the axis of rotation (d) in relation to the input part, against the action of a spring mechanism (14), and a hydrodynamic torque converter (3) comprising a turbine wheel (6), a pump wheel (5) and a torque converter clutch (10). The aim of the invention is to provide an axially narrow torque-transmitting device (1). To this end, the torque converter clutch (10) is arranged on the outer periphery of the turbine wheel (6) and the pump wheel (5), and the spring mechanism (14) intersects the axial installation space of the turbine wheel (6).

Description

technical field [0001] The invention relates to a torque transmission device having a dual-mass flywheel having: an input member arranged in a twistable manner about an axis of rotation; an output member arranged in a twisting manner to the axis of rotation; and a torque converter having a turbine, an impeller, and a torque converter clutch. Background technique [0002] Such a torque transmission device is installed, for example, in the drive train of a vehicle with an internal combustion engine and a transmission, in particular designed as an automatic transmission, and usually includes a hydrodynamic torque converter arranged between the internal combustion engine and the automatic transmission as a starting element. In this case, in order to save energy, the torque converter includes a torque converter jumper clutch, which bridges the fluid torque transmission at higher speeds. During the downsizing of internal combustion engines, for example with cylinder closures and ...
