Patent ID: 7350430

Claim:
A transmission for a motor vehicle, having a transmission input shaft ( 1 ), a transmission output shaft ( 2 ), and at least one countershaft ( 3 ), the transmission input shaft ( 1 ) the transmission output shaft ( 2 ), and the at least one countershaft ( 3 ) each supporting at least one gear, the transmission having a transmission direct gear for directly coupling the transmission input shaft ( 1 ) with the transmission output shaft ( 2 ); a range group being arranged downstream of the transmission, the range group having a range group input shaft ( 1 ′) and a range group output shaft ( 2 ′) and a range group direct gear for directly connecting the range group input shaft ( 1 ′) to the range group output shaft ( 2 ′); the transmission having a transmission direct gear shift element which, upon engagement of the transmission direct gear shift element, attains the transmission direct gear; and the range group having a range group direct gear shift element which, upon engagement of the range group direct gear shift element, attains range group direct gear; wherein when the transmission direct gear couples the transmission input shaft ( 1 ) to the transmission output shaft ( 2 ) and when the range group direct gear directly connects the range group input shaft ( 1 ′) to the range group output shaft ( 2 ′), only the transmission input shaft ( 1 ), the transmission output shaft ( 2 ), the range group input shaft ( 1 ′) and the range group output shaft ( 2 ′), along with the transmission direct gear, the range group direct gear, the transmission direct gear shift element and the range group direct gear shift element, rotate so as to minimize friction losses within the transmission and the range group.
