Beschreibung,Description,

Die Erfindung bezieht sich auf ein automatisches stufen» loses Gettiebe für Kraftfahrzeuge, dessen Steuerung von der Fahrgeschwindigkeit des Fahrzeuges abhängig ist«The invention relates to an automatic stepping » loose gearbox for motor vehicles, the control of which is controlled by the Driving speed of the vehicle is dependent "

Bei dem zur Zeit bekannten automatischen stufenlosen Getriebe erfolgt die Regelung desselben durch die auf der Kurbelwelle angebrachten Pliehkraftregelung. Diese Fliehkraftregelung bewirkt durch Veränderung der Motordrehzahl, daß die ieilriemenscheiben mehr oder weniger zusammengepreßt werden und sich dadurch das übersetzungsverhältnis des Getriebes,ändert» Bei dieses Setriebe ist es daher nicht möglich im ersten Gang mit voller Biotordrehzahl zu fahren» da sich dieser nur bei niedriger Motordrehzahl einstellt. Ss steht also z.B. bei einer Steigung, die gerade hier so sehr benötigte Leistung nicht voll zur Verfügung. Außerdem erhält man die größte Übersetzung, und damit die größte Fahrzeuggeschwindigkeit nur, wenn acr Motor auf vollen ren läuft.In the case of the currently known automatic continuously variable transmission, the regulation of the same is carried out by the thrust force regulation attached to the crankshaft. By changing the engine speed, this centrifugal force control causes the belt pulleys to be more or less compressed and the transmission ratio of the gearbox changes adjusts. Ss is therefore not fully available on an incline, for example, with the power that is so much needed here. In addition, the greatest gear ratio is obtained, and thus the greatest vehicle speed , only when the engine is running at full speed.

Gegenstand dcT Erfindung ist nun, das übersetzungsverhältnis des automatischen stufenlosen Getriebes in Abhän- . gigkeit von der Fahrzeuggeschwindigkeit zu regeln· Man kann dadurch sowohl mit niedrigem Sang und roller Kotordrehzahl eine Steigung bewältigen, als auch mit größerer Geschwindigkeit fahren ohne dabei den Motor hoch jagen zu müssen. DCT subject invention is now, the gear ratio of the automatic continuously variable transmission in depen-. ability to regulate the vehicle speed · You can cope with an incline with low engine speed and roller speed, as well as drive at higher speed without having to run up the engine.

Gemäß der Erfindung erfolgt die automatische Verstellung dieses automatischen stufenlosen Getriebes mittels Fliehkraftregelung a, welche auf der Abtriebswelle b sitzt und dadurch von ά^τ Motordrehzahl unabhängig ist«According to the invention, the automatic adjustment is carried out of this automatic continuously variable transmission by means of centrifugal force control a, b which sits on the output shaft and is thus independent of ά ^ τ engine speed "
