ABSTRACT:
A drive transmission unit for a motor vehicle incorporates an expansible-pulley stepless speed changer 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 secondary shaft parallel to, and driven from, the primary shaft. An output shaft of the transmission unit is positioned adjacent one end of the secondary shaft of the speed changer in coaxial alignment therewith and is operatively connected to the secondary shaft by the reversing unit. The reversing unit, which is of epicyclic form, is driven from said one end of the secondary shaft and 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. The reversing unit is coaxial with the secondary and output shafts so that the overall transmission unit is very compact.
