System components
Sequential M gearbox SMG 3
Transmission ratio of the SMG 3
The SMG 3 is designed as an overdrive
gearbox as can be clearly seen in the overview
of gear ratios.
A special feature of this gearbox is that the
main shaft is mounted in three bearing
assemblies. The third bearing assembly has
been realized by an end shield bolted in the
gearbox casing.
