Abstract
An interaxle differential system connecting two driven axles of a motor vehicle comprises a restrainable differential and a planetary gear train, which comprises three torque-transmitting members which have parallel axes. Two of said torque-transmitting members are operatively connected to two output shafts of the differential. A restraining device is connected to the third of said torque-transmitting members. In an interaxle differential system for use in a passenger car, the restraining device is a controllable liquid friction coupling, one coupling half of which is held against rotation.
