An interaxle differential for connection between two driven axles (14) of a motor vehicle comprises a liquid friction coupling (1) and a planetary gear train (15) comprising three torque-transmitting members (16, 18, 20). The liquid friction coupling (1) comprises a liquid-filled housing, a coupling shaft, which coaxially protrudes into said housing at least one set of radially inwardly extending, axially spaced apart outer blades, which are mounted on the housing, and radially outwardly extending, axially spaced apart inner blades, which are fixed to the shaft in said housing and axially staggered from the outer blades. Each of said outer blades is adjustable in a radial plane to vary the radial overlap between the outer and inner blades. A first of said torque-transmitting members of the planetary gear train is directly connected to an input member of the differential gear. A second (20) of said torque-transmitting members is connected to said coupling shaft (3). Only a third (18) of said torque-transmitting members is connected in said differential to an output member (19) of the differential. The housing (2) of the liquid friction coupling (1) is held against rotation. |
