Embodiment Construction

[0032] figure 1 A device 100 for transmitting torque about an axis of rotation 105 is shown. An input side 110 and an output side 115 are provided by way of example. Device 110 is provided in particular for use in a drive train of a motor vehicle. The input side 110 can be connected, in particular, to a drive motor, for example an internal combustion engine, and the output side 115 can be connected to a transmission. The device 110 includes a torque converter 120 and a friction clutch 125 , which are both arranged in parallel with one another between the input side 110 and the output side 115 .

[0033] The torque converter 120 includes an impeller 130 and a turbine 135 . The impeller 130 includes impeller blades 140 and the turbine wheel 135 includes impeller blades 145 , which lie axially opposite each other. In a preferred embodiment, the guide wheel 150 is provided with guide wheel blades 155 which are arranged on a predetermined radial section between the pump wheel b...

Abstract

A device for transmitting torque comprises a hydrodynamic torque converter having a turbine and a pump, as well as a friction clutch which is connected in parallel to the torque converter, having a first and a second friction partner. In this context, the first friction partner is produced integrated with the pump and the second friction partner integrated with the turbine. A ring-shaped friction section, on which the friction elements can be axially engaged with one another, and a ring-shaped flow section, on which vanes of the pump and of the turbine are axially facing one another, are dimensionally adapted to one another in order to realize a balanced transmission behavior.

Description

technical field [0001] The invention relates to a device for transmitting torque. In particular, the invention relates to a hydrodynamic torque converter with a clutch. Background technique [0002] Devices used to transmit torque include torque converters and friction clutches. A friction clutch is connected in parallel with the torque converter in order to bridge the torque converter, for example after a start-up process. [0003] A known hydrodynamic torque converter with an overrunning clutch is relatively complex in its construction and can therefore be relatively expensive to produce. It is therefore the object of the present invention to provide an improved hydrodynamic torque converter with a clutch. The invention solves this object by means of a device for transmitting torque having the features of the independent claim. The dependent claims enumerate preferred embodiments. Contents of the invention [0004] The device for transmitting torque includes a hydra...
