Double-cone synchronisation
As a result of the speed difference to be
eliminated in the lower gears, the synchronisation
forces may be considerable. In order to achieve
effective synchronisation, a synchroniser with a
double cone is used.
This synchroniser consists of an outer and an
inner ring (synchromesh rings) connected to the
main shaft of the gearbox by means of the
selector sleeve support.
The ring between the two synchromesh rings is
connected to the gear wheel by means of the
selector ring.
When the selector sleeve moves into the selector
ring, two synchronisation surfaces are active.
