Abstract
A drive transmission unit for a motor vehicle incorporates an expansible-pulley stepless speed changer arranged to drive a differential unit via a reduction gear box and a selectively-operable reversing unit. The speed changer has a primary shaft which serves as the input shaft of the transmission unit, and a hollow secondary shaft parallel to, and driven from, the primary shaft. The reversing unit, reduction gear box and differential unit are all epicyclic in form and are arranged in that order side-by-side coaxial with the secondary shaft. Two output shafts connect the differential unit to the half shafts of the vehicle with one of the output shafts passing coaxially through the secondary shaft. This arrangement provides for a very compact transmission unit. The reversing unit can be set in one of three states in which respectively, the secondary and output shafts are arranged to rotate in the same sense, to rotate in opposite senses, and to be drivingly disengaged.
