Figure 3.4.1 – Speed unit (developed view)
A drum 9 (figure 3.4.2) of the twinned friction clutch has bores (cavities) on both
sides, into which movable pistons 4 are mounted, sealed by cast iron split rings 1 and 7.
In each piston cavities eighteen release springs 8 are mounted, which have previously
been compressed by spring bolster 10, fixed on the hub of the drum 9 by a lock ring 6. Two
guide pins 5 are pressed into the spring bolster 10.
There are two centrifugal ball valves 3 to collect working fluid from boosters of the friction
clutch after they are detached from the discharge manifold of gearbox control.
