Embodiment Construction

[0032] figure 1 A device 100 for transmitting torque about an axis of rotation 105 is shown. The input side 110 and the output side 115 are provided by way of example. Device 110 is provided in particular for use in a drive train in a motor vehicle. The input side 110 can in particular be connected to a drive engine, 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 , both of which are arranged in parallel with each other between the input side 110 and the output side 115 .

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

Abstract

A device for transmitting torque includes a hydrodynamic torque converter having a turbine and a pump, as well as a friction clutch that is connected in parallel to the torque converter, having a first and a second frictional segment. The first frictional segment is integrated with the pump, and the second frictional segment is integrated with the turbine. A ring-shaped frictional segment, on which the frictional elements may be brought into engagement with each other axially, and a ring-shaped flow segment, on which vanes of the pump and of the turbine are located opposite each other axially, are matched with one another in their dimensions, in order to realize a balanced transmission behavior.

Description

technical field [0001] The present invention relates to a device for transmitting torque. In particular, the invention relates to a torque converter with a bridging clutch. Background technique [0002] Devices for transmitting torque include torque converters and friction clutches. The friction clutch is connected in parallel with the torque converter in order to bridge the torque converter, for example after a starting procedure. [0003] A known torque converter with a bridging clutch is relatively complex in its construction and therefore relatively expensive to manufacture. It is therefore an object of the present invention to provide an improved torque converter with a bridging clutch. The present invention solves this task by means of a device for transmitting torque. SUMMARY OF THE INVENTION [0004] The device for transmitting torque includes a torque converter and a friction clutch, the torque converter includes a turbine and a pump impeller, the friction clu...
