A fluid friction clutch may include a rotatably mounted shaft, a drive disk arranged on the shaft in a rotationally fixed manner, a driven body rotatably arranged on the shaft, and a ring-shaped transfer region disposed between the drive disk and the driven body. The transfer region may be configured to receive a viscous fluid via which the drive disk is couplable to the driven body for transferring a torque. The transfer region may be defined by a ring-shaped first groove profile of the drive disk and a ring-shaped second groove profile of the driven body that engage one another axially. The clutch may also include a storage chamber fluidically connected to the transfer region via an inflow path and via a return path. The return path may include a first retaining body and a second retaining body arranged radially offset relative to one another by an arc angle.

Fluid friction clutch

A hydrodynamic friction clutch may include a rotatably mounted shaft, a drive disc non-rotatably fixed on the shaft, and an output body rotatably fixed on the shaft. The drive disc may include a radially extending annular transmission region for receiving a viscous fluid and via which the drive disc may be couplable to the output body for transmitting a torque, and an annular segment-shaped storage chamber for receiving the viscous fluid. The transmission region may be fluidically connected to the storage chamber via an inlet path and a drainage path. In the inlet path, a closable valve opening for controlling the quantity of the viscous fluid in the transmission region may be provided. The inlet path may include an annular segment-shaped communication passage, which may fluidically connect the storage chamber to the valve opening. The drainage path may fluidically connect to the inlet path at the valve opening.
