Abstract
An apparatus for rear-driving an automotive vehicle having a drive power source, an output member operatively connected to a drive wheel, a gear type synthesizing/distributing device including a housing, and a first, a second and a third rotary element, the first and second rotary elements being rotated in respective opposite directions when the third rotary element is stationary, and connected to the drive power source and the output member, respectively, and a brake or fixing the third rotary element to the housing, wherein the brake is a frictional coupling device capable of effecting a slipping engagement. The apparatus includes a reverse friction-drive control device which is operable when the first rotary element is rotated in a forward direction with an operation of the drive power source, while the third rotary element is rotated in the forward direction with a rotary motion of the first rotary element, the reverse friction-drive control device controlling the brake to effect the slipping engagement so as to restrict a rotary motion of the third rotary element, for thereby causing a drive torque to act on the second rotary element in a reverse direction to drive the vehicle…
