Abstract: A liquid friction coupling is disclosed, which comprises a housing, which constitutes one coupling part and is filled with a viscous liquid, a shaft, which protrudes into the housing and constitutes the other coupling part, interdigitating disks, which are nonrotatably connected in alternation to the housing and to the shaft, respectively, and spacers disposed between the disks. In order to improve the torque characteristic during an operation involving liquid friction and to achieve a steeper rise of the hump torque, each of the outer or inner disks entirely or in part tends to exhibit a thermal deformation in an axial direction and a spacer ring is provided between each inner disk and an outer disk of an adjacent pair of disks.
