Abstract
A change-speed transmission for motor vehicles, with the transmission including a planetary gear transmission arrangement having a pair of sun gears, a pair of ring gears, and a double webbed planetary gear carrier supporting at least one primary planetary gear and at least one secondary planetary gear. The primary planetary gear meshes with one of the sun gears and the secondary planetary gear meshes with the primary planetary gear and the other of the sun gears. One sun gear, acting as a free transmisson member and one ring gear are respectively adapted to be brought into an operative connection by a gear shift brake arrangement. The other sun gear as well as a further transmission member may be placed in a driving connection with the input shaft of the transmission. Both ring gears mesh with the primary planetary gear and one of the ring gears as well as the transmission member acting on the output shaft may be brought into driving connection respectively with one transmission member of a planetary gear coupling transmission. An additional transmission member of the planetary gear coupling transmission is adapted to be connected to the output shaft of the transmission.
