Embodiment Construction

[0051] Similar or similarly acting elements are identified below with the same reference numerals.

[0052] figure 1 A wet-running clutch assembly 1 in the form of a hydraulic torque converter is shown. On its side facing the drive (not shown), the housing 2 has a housing cover 4 which is fixedly connected to the impeller housing 6 . The impeller housing 6 merges into the impeller hub 8 in the radially inner region.

[0053] The impeller casing 6 together with the impeller blades forms a pump impeller 10 which cooperates with a turbine 14 having a turbine casing 12 with turbine blades and a stator 16 with stator blades. The pump wheel 10 , the turbine wheel 14 and the guide wheel 16 form a hydraulic circuit in a known manner.

[0054] The guide wheel 16 is arranged on a freewheel 18 which is supported axially on the pump hub 8 via an axial bearing 20 . The pump hub 8 is hollow and therefore accommodates the transmission input shaft 22 in its interior.

[0055] The transmi...

Abstract

A torque transmission device, particularly for a motor vehicle, for the transmission of a torque from a driving unit, particularly from an internal combustion engine, to a driven unit, particularly a transmission, has at least one bearing (18,20,28,30,35,504,508,604,610,704,708,804,808)location which has at least one bearing support acting in axial and / or radial direction, wherein an insulation element(40) preventing a flow of electric current is provided in the region of the at least one bearing (18,20,28,30,35,504,508,604,610,704,708,804,808)location.

Description

technical field [0001] The invention relates to a torque transmission device, in particular for a motor vehicle, to transmit torque from a drive unit, in particular from an internal combustion engine, to an output unit, in particular to a transmission with at least one bearing support frame (Lagerstelle), the bearing support The carrier has bearings acting in at least one axial and / or radial direction. Background technique [0002] This type of torque transmitting device may be, for example, a clutch pack, a twin inertia flywheel, or a torque converter. This type of torque transmitting device is usually arranged in the powertrain of a vehicle between a drive unit (engine) and an output unit (transmission). However, it has been shown in modern powertrains that during starting of the vehicle via the starter, although the main part of the current can, as usual, be directed to the body via the ground wire, the remaining current intensity can be obtained from the starter Engine...
