Problems solved by technology

[0002] In wet-running clutch arrangements, the problem is that, after a relatively long idle time, during driving operation, the fluid contained in the housing arrangement partially escapes from the housing arrangement and flows, for example, into a fluid sump in the gearbox.
However, because fluid is generally required to engage the friction clutch areas, a state of inability to transmit torque may occur for a period of time after start of operation due to the lack of possibility of filling the piston cavity and thus engaging the friction clutch areas

Embodiment Construction

[0045] figure 1 In general, 10 denotes a clutch device for operating the drive train of a vehicle. This clutch device 10, which can be used as a starting element, comprises a housing device 12 with a housing shell 14 to be positioned close to the engine, that is to say on the engine side, and a housing shell 14 to be positioned close to the transmission, that is to say on the transmission side. Housing shell 16 . The two housing shells 14 , 16 are fixedly connected to one another, for example by welding, in regions 15 , 17 of which radially outer sides extend one above the other, and together define an interior 18 of the housing arrangement 12 . A clutch device 20 is provided on the engine-side housing shell 14 , by means of which the housing device 12 can be connected for common rotation about an axis of rotation A with a drive shaft (eg a crankshaft of an internal combustion engine), for example by means of a bent plate arrangement or the like. In its radially inner region...

Abstract

The invention relates to a wet clutch arrangement, in particular a drive clutch, for a vehicle, comprising a housing arrangement (12) that is or can be filled with fluid, a friction clutch region (26) having a first friction surface formation (44) rotating with the housing arrangement (12) about a rotary axis (A), and a second friction surface formation (46) that rotates with a drive element (96) about the rotary axis (A) and that can be brought into frictional engagement with the first friction surface arrangement (44), a fluid clutch region (24) having an pump wheel (28) rotating with the housing arrangement (12) about the rotary axis (A), and a turbine wheel (36), the drive element (96) of which rotates about the rotary axis (A) and delimits a toroidal fluid circulation chamber (42) with the pump wheel (28). The invention is characterized in that the fluid clutch region (24) is arranged radially outside of the friction clutch region (26).

Description

technical field [0001] The invention relates to a wet-running clutch arrangement, in particular a starter clutch for a vehicle, comprising a fluid-filled or fluid-fillable housing arrangement, a friction clutch region and a fluid clutch region, the friction clutch region Having a first frictional surface structure that rotates with the housing device around the axis of rotation and a second frictional surface structure that rotates with the driven element around the axis of rotation and that can be brought into frictional engagement with the first frictional surface structure, the fluid clutch region has A pump wheel rotates with the housing arrangement about the axis of rotation, and a turbine wheel rotates with the driven element about the axis of rotation and together with the pump wheel defines a fluid circulation annular chamber. Background technique [0002] In wet-running clutch arrangements, the problem is that, after a relatively long idle time, during driving opera...
