  • Publication number: 20050115345
    Abstract: A transmission having one starting and/or gear clutch, the input side is connected with one drive shaft of a prime mover and the output side (8) with a transmission input shaft; one countershaft is supported or fastened speed gear wheels designed as idler gears or as fixed gears which mesh with speed gear wheels non-rotatably situated upon the transmission input shaft and designed as fixed gears or rotatably supported and designed as idler gears, and shifting sets, which for connecting the idler gears with the respectively coordinates shaft, are non-rotatably and axially movably supported upon the shaft and axially movable there via setting devices. For reducing the development, production and storage costs in transmissions of similar design, the transmission input shaft is comprised of at least two non-rotatably interconnected part shafts.
