Abstract
A torque transmission device includes a torque converter, a pump impeller, a turbine wheel and optionally a stator. The device also includes a converter bypass coupling having a flange which is connected to the housing or the pump impeller in a force-locking manner. The flange is arranged between the pump impeller and the turbine wheel and can be connected to the turbine wheel in a frictionally engaged manner by means of a first coupling.
Claims17
A torque transmission device for a motor vehicle, the torque transmission device being a fluid coupling device being one of a Föttinger device and a torque converter, comprising:
- an impeller connectable in a torsionally fixed manner to a drive shaft;
- a turbine connectable in a torsionally fixed manner to an input shaft;
- a housing accommodating the impeller and the turbine;
- a converter lockup clutch configured to lock together the impeller and the turbine in a torsionally fixed manner;
- a flange disposed axially between the impeller and the turbine and connected in a force-locking manner to at least one of the housing and the impeller, the flange also being radially disposed outside of a radially outer end of the impeller and the turbine;
- and
- a first coupling configured to connect the flange in a frictionally engaged manner to the turbine.
The torque transmission device as recited in 7, wherein the friction clutch includes a friction lining.
