Abstract

A wet clutch arrangement, particularly starting clutch for a vehicle, including a housing arrangement which is filled or fillable with fluid, a friction coupling region having a first friction surface formation rotating with the housing arrangement around an axis of rotation and a second friction surface formation that rotates with a driven element around the axis of rotation and which can be brought into frictional engagement with the first friction surface formation, a fluid coupling region with an impeller rotating with the housing arrangement around the axis of rotation and with a turbine that rotates with the driven element around the axis of rotation and which, along with the impeller, defines a toroidal fluid circulation space. The fluid coupling region is arranged radially outside the friction coupling region.
