Epicyclic gears, in particular

for agriculturally nutabare motorfaoraeugo

The invention relates to “in epicyclic gears, in particular for agriculturally nutsable Uotorfahrsauge, with a shaft that can be continuously driven and connected to a member“ for example a sun wheel, and a “over” ine drthaahlkoastant revolving “nflt shaft” ahlweiee membered _t epieleweise UmlauXrttdertrager that as a the laufrädtrtrttge * with its drive Terbindende, beiepiels example kraftaonlUesige clutch, a further clutch and a tone of constant speed rotating shaft driven drive element for the epicyclic carrier are also arranged coaxially to the drehzahlverändernoh rotating shaft, wherein a Auegangswelle is connected variable-speed transmission, for example, the ring gear - with a third member of the UmlaufrMder. Every task to be carried out with the object of the ignition is seen in it »the planetary wheel drive gearbox is subdivided into a more subtle way than before«

As is well known, the turning axes of a rotating gear consisting of sundring gear "UaOaufohen ^ fran ^räderträ I ^er *** ^ ohlrad consisting of UmlaufraderwtehselgetrItsösisohe bee" can be controlled, where the sun gear, which serves as the input glitd of the Ualaufsohrift gear reversing gear, is driven via a steplessly adjustable gear serve as the output link of the gearwheels * the ring gears can be varied depending on the turning speed of the continuously variable transmission. Here, the single links of the epicyclic gearwheel gear can be coupled either with one another or with a drthaahlvtrindtrlieh, from the continuously adjustable gear on the gearbox.

The task "iat according to the invention was thereby solved" that there is the sun gear with the planetary gear carrier or the ring gear Can be connected via the other coupling and the circulation wheel-to-wheel drive a gearwheel gearbox naohaohaltbar iat · * uf This way, the epicyclic gears are intruded Construction, because the drive το «sun gear is carried out directly on the ring gear or the planetary gear carrier» eo that enough flats for additional additional units »beiapielewelae daa steering gear, available at ent. Let through the direct drive furthermore with relatively few components «in hollow leasable Gear made »daa the requirements Ib rough Sinamta in the agriculture, forestry and building management aXt is ruled »where In addition, through the i-itJgliohkeit, a gearsweohselgetrlebe Follow the revolving gears, the speed can be varied in different ways can be enlarged or reduced for forward and reverse travel.

Another advantage is the further coupling of the idler gears formed as a friction clutch, what makes itself constant a smooth transition τοη a speed range sum can reach others · Furthermore, friction clutches are more space-saving to be arranged as, for example, formsehlttsalga couplings, which in turn contributes to a compact design «

According to a further feature of the finding, the sun gear with the revolving wheel carrier or the friction clutch connecting the ring gear Ring lamellas aufweiaea »which partly with dar daa Sun wheel receiving »drehaahlTeränderlioh circumferential wall or directly with the sun gear * parts with the planetary gear carrier or connected to the bellwheel.

reioh can be achieved. Through the arrangement of the lamellar the result is large effective surfaces «eo da · the greatest diameter * the slats can be kept correspondingly smaller.

So that the installation * of the clutches can be done more easily and the access to the clutches in the gearbox not complicates it, the invention can incorporate the sun gear with the Umleufraderträger or the friction clutch connecting the ring gear on one side of the Umlaufraderweohselgetriebte next to the the TTmlaufradentrräger old its drive connecting frictional Coupling to be arranged »whose single lamellas are partly connected to the drive element, partly to the planetary gear carrier are.
