ABSTRACT:
A multi-step reduction gear having a drive shaft (1) connected to a front-mounted gear group (VS) having switch elements (A, B, C, D, E) which is connected to a rear-mounted gear group (NS) having switch elements (M, H, L) by a spacer shaft (2) rotating at an output speed (nvs) of the front-mounted gear group (VS). An input speed (n) of the drive shaft (1) can be transmitted to an output shaft (3) for at least seven forward gears wherein a change from one gear to the next highest or next lowest gear only requires a disconnection of one switch element and a connection of one other switch element.
