Abstract
Description
Die vorliegende Erfindung betrifft ein Getriebe gemäß dem Oberbegriff des Patentanspruches 1.The The present invention relates to a transmission according to the preamble of claim 1.
Bei der Konstruktion von Getrieben muss darauf geachtet werden, dass in jedem Betriebszustand eine hinreichende Schmierung gewährleistet ist. Hiermit in Konflikt steht das Bestreben, Planschverluste an drehenden Teilen, insbesondere an Zahnrädern zu minimieren.at The design of gearboxes must be taken to ensure that In any operating condition adequate lubrication is guaranteed. This conflicts with the desire to splash on spinning Parts, in particular on gears to minimize.
Aufgabe der Erfindung ist es, ein Getriebe mit einer Ölrückhalteeinrichtung zu schaffen, die in konstruktiv einfacher Weise eine Verringerung der Planschverluste ermöglicht.task the invention is to provide a transmission with an oil retaining device, in a structurally simple way to reduce the churning losses allows.
Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung sind den Unteransprüchen zu entnehmen.These The object is solved by the features of claim 1. advantageous Refinements and developments of the invention are the dependent claims remove.
Ausgangspunkt der Erfindung ist ein Getriebe, insbesondere ein Achsgetriebe, mit einem Gehäuse, einem im Gehäuse angeordneten Zahnrad und einer Ölrückhalteeinrichtung. Das Gehäuse weist einen unteren Gehäuseteil auf, der bis zu einer gewissen Höhe mit Getriebeöl befüllt ist. Das in dem unterem Gehäuseteil befindliche Getriebeöl wird als „Ölsumpf” bezeichnet. Das Zahnrad, das im Falle, dass es sich bei dem Getriebe um ein Achsgetriebe handelt, ein Tellerrad sein kann, ist zumindest bis zu einer gewissen Eintauchtiefe in den Ölsumpf eingetaucht. Die Ölrückhalteeinrichtung ist dazu vorgesehen, während des Betriebs des Getriebes den Zufluss von Öl aus dem Ölsumpf zu dem Zahnrad zu begrenzen, um dadurch Planschverluste am Zahnrad zu verringern.starting point The invention is a transmission, in particular an axle, with a housing, one in the housing arranged gear and an oil retaining device. The housing faces a lower housing part up to a certain height with gear oil filled is. The in the lower housing part located transmission oil is called "oil sump". The gear, which in case that it is in the gearbox Achsgetriebe acts, a ring gear can be, is at least until immersed in the oil sump to a certain depth of immersion. The oil retention device is intended while the operation of the transmission to limit the flow of oil from the oil sump to the gear, to thereby reduce churning losses on the gear.
Der Kern der Erfindung besteht darin, dass die Ölrückhalteeinrichtung zumindest teilweise in den Ölsumpf eingetaucht ist und in Abhängigkeit von der Drehrichtung des Zahnrads einen gewissen Rückstau des Getriebeöls bewirkt. „Rückstau” bedeutet, dass das Zahnrad im Betrieb weniger weit in den Ölsumpf eingetaucht ist als bei stehendem Getriebe, wodurch sich Planschverluste verringern lassen.Of the Essence of the invention is that the oil retaining device at least partly in the oil sump immersed and depending from the direction of rotation of the gear a certain backwater of the transmission oil causes. "Backwater" means that the gear is less immersed in the oil sump during operation with the gearbox stationary, which reduces churning losses to let.
Bei der Ölrückhalteeinrichtung kann es sich z. B. um eine geschlitzte Platte oder um ein geschlitztes Blech handeln, welche das Zahnrad vom unteren Gehäuseteil her übergreift.at the oil retention device can it be z. B. a slotted plate or a slotted Tin act, which the gear from the lower housing part spreads over.
Alternativ dazu kann es sich bei der Ölrückhalteeinrichtung auch um ein „wannenartiges” Element handeln, vergleichbar einem Fahrradschutzblech, welches das Zahnrad von unten her übergreift und sich über einen gewissen Umfang des Zahnrads erstreckt.alternative this can happen with the oil retention device also a "tub-like" element act, comparable to a bicycle apron which holds the gear from below and over over extends a certain extent of the gear.
