In addition, clutch apparatus 1 can also be embodied as tool, there are two the double clutches of pump 12.Pump 12 clutches by rotation
Between device and motionless shell (speed changer and/or internal combustion engine shell) can the connection of electrodeless adjustment drive.This can be with
Most simply implement, mode is that pump shaft/pump drive shaft 13 passes through brake/brake apparatus 14 between clutch and shell
To drive.This can be mechanical or electric-type brake (such as disk brake, eddy-current brake, generator).
Hydraulic pressure is generated by pump 12, the hydraulic pressure is manipulated by same co-rotational cylinder (pump receives shell)
Clutch/clutch apparatus 1.Choke block 23 is installed in pressure piping/pressure pipeline 19, fluid is flowed back to by the choke block
Into hold-up vessel 21.Thus adjusting is made to become easy.Clutch apparatus 1 is preferably direct operated, normally opened.Clutch
Other embodiment (lever-operated, normally closed ...) be essentially possible.
In addition, rotation actuator be not only able to combine with so-called dry clutch system, and can with it is so-called wet
Formula clutch system combines.Hold-up vessel 21 is equipped in bellows or inflates the volumetric balance equipment of form membrane.
Two of double clutch pumps 12 be located at it is almost the same diametrically, wherein outlet is in corresponding relay piston/manipulation
Piston 8 diametrically, influences the eccentric force of fluid to reduce.Hold-up vessel 21 can alternatively be connect with compensating piston,
It is influenced therefore to reduce eccentric force.Thus pump 12 need not be located on radius identical with relay piston again.If brake is real
Apply as generator, then when use is in hybrid vehicle burner it is motionless/internal combustion engine 4 it is motionless in the case of, generator
It can be used as engine, and therefore clutch be made to be closed.This is firstly for being beneficial for hybrid power strategy.From
The closure of clutch is carried out by operating brakes.Due to choke block 23, existing between braking moment and clutch torque can
The relevance of calculating.Clutch is opens voluntarily.That is, only must release brake in order to open clutch.
