| 摘要 |
The invention relates to a multistep reduction gear comprising a drive shaft (1) which is connected to a front-mounted group (VS), an output shaft (3) which is connected to a rear-mounted group (NS), switch elements (A, B, C, D, E) acting on the front-mounted group (VS) and switch elements (M, H, L) acting on the rear-mounted group (NS). By selectively switching said switch elements (A, B, C, D, E and M, H, L), an input speed (n) of the drive shaft (1) is transferred to the output shaft (3) for passing at least seven forward gears, in such a way that in order to change to the next highest or next lowest gear by means of the switch elements which have just been actuated, respectively only one switching element is disconnected and a further switch element is connected. |
