Description
Hydrauliche,achsialdruck und stufenlose Regelvorrichtung für Vielscheiben-Keilriemengetriebe B e S c h r e i b u n g Zur Patentanmeldung: Aktenzeichen P 19 28 795 . 7 "Vielscheiben-Verstellvorrichtung für stufenlos regelbare Keilriemengetriebe insbesondere für große Drehmomentwandlung ft Bei der oben beschriebenen Erfindung erfolgt die stufenlose Verstellung der verschiebbaren Keilriemen-Kegelscheiben mittels Gewinde über die Lagerung der An- und Abtrieswellen der Keilriemengruppe wobei bei größeren Leistungen und der dazu erforderlichen hohen Keilriemengeschwindigkeit und Drehzahl eine große Ächsialbelastung der Lagerung statt findet und deswegen Oeldruck geschmierte Lager verwendet werden müssen. Hydraulic, axial pressure and stepless control device for multi-pulley V-belt drive R e c e r i n g e for patent application: file number P 19 28 795. 7 "multi-disc adjustment device for continuously variable V-belt transmissions, especially for large torque conversion ft In the invention described above, the stepless adjustment of the sliding V-belt conical pulleys by means of a thread over the bearing of the input and output shafts the V-belt group, with greater performance and the high level required for this V-belt speed and rotational speed place a large axial load on the bearing takes place and therefore oil pressure lubricated bearings must be used.
Mit der vorliegenden Erfindung wird der Achsialdruck auf die Lager in einfachster Weise dadurch aufgehoben, indem auf den An- und Abtriebswellen einer Keilriemengruppe Oeldruckzylinder mit den feststehenden Keilriemen-Kegelscheiben verbunden sind und die verschiebbaren.gegenteiligen Kegelscheiben mit den Druckkolben, der zur stufenlosen Verstellung nötige Achsialdruck über zentrale Bohrungen und Rohrleitungen auf den beidseitig wirkenden Kolben eines Steuerzylinders und über dessen Schubstange auf eine Gewindeveratellto*ichtung übertragen ist. With the present invention, the axial pressure on the bearings is reduced repealed in the simplest way by one on the input and output shafts V-belt group oil pressure cylinder with the fixed V-belt cone pulleys are connected and the displaceable, opposing conical disks with the pressure pistons, the axial pressure required for stepless adjustment via central bores and Pipelines on the double-acting piston of a control cylinder and over whose push rod is transferred to a threaded adjustment mechanism.
Bei mehreren zusammen wirkenden Keilriemengruppen für große Untersetzungsverhältniße muß wegen des verschiedenen Drehmomentes und damit Achsialdruckes jede Keilriemengruppe ihren eigenen Steuerzylinder haben,aber über die Schubstangen miteinander verbundentgemeinsam mit der Gewindeverstellvorichtung stufenlos geregelt seineDie Keilriemengruppen können über die Rohrleitungen auch fern- oder fremd geregelt sein0 In der Zeichnung i8t die Erfindung in Fig.S verkürze im Längsschnitt dargestellt.Fig.IS zeigt eine zweifache Keilriemengruppe mit den Regelorganen. With several working V-belt groups for large reduction ratios each V-belt group must because of the different torque and thus axial pressure have their own control cylinder, but are connected to each other via the push rods The V-belt groups are continuously regulated with the thread adjustment device can also be controlled remotely or externally via the pipelines0 In the drawing i8t the invention in Fig. S is shown briefly in longitudinal section. Fig.IS shows a double V-belt group with the regulating organs.
Auf den An- und Abtreibswellen 1 sind zwischen den Gewindemuttern 2 die mit den Wellen fest verbundenen Kegelscheiben 3 mit Rohrhülsen 4 und dem Oeldruckzylinder 5 befestigt Die,zwischen den feststehenden Kegelscheiben, verschiebbaren gegenteiligen Kegelscheiben 6 mit den Rohrhülsen 7 wid durchgehenden Verbindungsbolzen 8 sindv mit dem Druckkolben 9 verbunden.Die hydrauliche Betätigung der Teile 6, 7, 8, 9 erfolgt über den beidseitig wirkenden Steuerkolben lo über die Schubstange 11 mit Gewindemuffe 12 und ist am Gehäuse 13 gehalten. On the input and output shafts 1 are between the threaded nuts 2 the conical disks 3 with pipe sleeves 4 and the oil pressure cylinder firmly connected to the shafts 5 attached The slidable ones between the fixed conical disks opposite conical disks 6 with the pipe sleeves 7 wid continuous connecting bolts 8 are connected to the pressure piston 9. The hydraulic actuation of the parts 6, 7, 8, 9 takes place via the control piston lo acting on both sides via the push rod 11 with threaded sleeve 12 and is held on housing 13.
Über dei ROhrleitung 14 mit Wellendurdhbohrung und Dichtung 15 sind sind der Steuerzylinder und die schubkolben 9 luftfrei mit Oel verbunden0 Fig. II Bei zwei zusammen gekoppelten Keilriemengruppen mit verschiedener Keilriemenzahl muß jede Keilriemengruppe wegen des verschiedenen Drehmomentes und damit A«hsialdruckes ihren eigenen Steuerzylinder haben,können aber über die Schubstange verbunden gemeinsam geregelt werden.About the pipe 14 with shaft end hole and seal 15 are the control cylinder and the thrust pistons 9 are air-free connected with oil 0 Fig. II With two V-belt groups coupled together with different numbers of V-belts each V-belt group must because of the different torque and thus axial pressure have their own control cylinder, but can be connected together via the push rod be managed.
