A torque-transmitting device for transmitting torque by utilizing the viscosity of a fluid includes a casing 13 having a cylindrical barrel having closed opposite ends, shafts 3,5 rotatably supported in the casing in coaxial relationship with the cylindrical barrel, a fluid chamber defined by an inner surface of the casing 13 and outer peripheral surfaces of the shafts, a plurality of annular outer plates 29 disposed in the fluid chamber and rotatable with the casing, a plurality of annular inner plates 31 disposed in the fluid chamber alternately with the outer plates and rotatable with the shafts, and a fluid located in the chamber. Flow passages are defined in the fluid chamber and extend axially of the shafts for allowing the fluid to flow in the fluid chamber to avoid localized temperature increases. The passages may be formed in the inner or outer peripheries of the plates or in the surfaces of the casing or the shafts. A gear pump (FIGS 9 and 10) may additionally be provided within the casing to provide forced oil circulation. …<IMAGE>… |
