Abstract
Description
Die Erfindung betrifft ein Automatgetriebe, insbesondere für Kraftfahrzeuge nach dem Oberbegriff des Patentanspruches 1.The The invention relates to an automatic transmission, in particular for motor vehicles according to the preamble of claim 1.
Automatgetriebe
für Kraftfahrzeuge
weisen ein oder zwei Planetengetriebe, so genannte Planetenradsätze auf,
wobei benachbart zu den Planetenradsätzen Schaltelemente, hydraulisch
betätigte Kupplungen
oder Bremsen, angeordnet sind. Eine derartige Anordnung eines Planentenradsatzes
neben einem Schaltelement mit einer Stauscheibe wurde durch die
Es ist Aufgabe der vorliegenden Erfindung, bei einem Automatgetriebe der eingangs genannten Art Koaxialitätsfehler zu vermeiden bzw. zu reduzieren, insbesondere bei der Anbindung von Planetenradträger und benachbarter Stauscheibe. Es ist auch Aufgabe der Erfindung, benachbarte Teile spielfrei mit dem Planetenträger zu verbinden.It Object of the present invention, in an automatic transmission to avoid coaxial errors of the type mentioned above or reduce, in particular in the connection of planet carrier and adjacent baffle plate. It is also an object of the invention, adjacent Connecting parts to the planet carrier without backlash.
Diese Aufgabe wird zunächst durch die Merkmale des Patentanspruches 1 gelöst. Erfindungsgemäß ist vorgesehen, dass der Planetenradträger direkt auf der Nabe des benachbarten Schaltelementes angeordnet und durch eine Mitnahmeverzahnung oder eine äquivalente Formschlussverbindung mit der Nabe verbunden ist. Dadurch wird der Vorteil eines um 50% reduzierten Koaxialitätsfehlers erreicht, indem die indirekte Anbindung des Planetenradträgers und der daraus resultierende höhere Koaxialitätsfehler vermieden werden. Als Vorteil ergibt sich ferner, dass die Lagerelemente der Zylindernabe, z. B. eine Zylinderbuchse weniger belastet sind und damit eine höhere Betriebssicherheit erreichen.These Task is first solved by the features of claim 1. According to the invention, it is provided that the planet carrier arranged directly on the hub of the adjacent switching element and by a driving toothing or an equivalent positive connection connected to the hub. This will increase the benefit of one by 50% achieved reduced coaxiality error, by the indirect connection of the planet carrier and the resulting higher coaxial errors be avoided. Another advantage is that the bearing elements the cylinder hub, z. B. a cylinder liner are less loaded and thus a higher one Achieve operational reliability.
Nach einer vorteilhaften Ausgestaltung der Erfindung ist die Mitnahmeverzahnung auf der Zylindernabe durchgehend sowohl für die Stauscheibe als auch für die Führungsscheibe des Planetenradträgers ausgebildet. Somit kann die Verzahnung für beide Teile in einem Arbeitsgang hergestellt werden und erfordert praktisch keinen zusätzlichen Fertigungsaufwand. Auch der axiale Bauraum wird durch die direkte Anbindung der Führungsscheibe an die Nabe nicht vergrößert, da die Nabe mit ihrer stirnseitigen Mitnahmeverzahnung in den Planetenträger hineinragt. Vorteilhafterweise ist die Mitnahmeverzahnung für die Führungsscheibe des Planetenträgers nur auf einzelnen Segmenten, insbesondere vier Segmenten auf dem Umfang angeordnet. Damit ergeben sich insbesondere für die Führungsscheibe Bauraumvorteile.To An advantageous embodiment of the invention is the driving teeth on the cylinder hub continuously for both the baffle plate and for the guide disc of the planet carrier educated. Thus, the teeth for both parts in one operation be prepared and requires virtually no additional Production expense. Also, the axial space is through the direct Connection of the guide disc to the hub not enlarged, there the hub protrudes with its front-end driving teeth in the planet carrier. Advantageously, the driving teeth for the guide plate of the planet carrier only on individual segments, in particular four segments on the circumference arranged. This results in particular for the guide disc space advantages.
Die Aufgabe der Erfindung wird auch durch die Merkmale des nebengeordneten Patentanspruches 4 gelöst. Erfindungsgemäß ist vorgesehen, dass die benachbarte Stauscheibe mit dem Planetenträger durch einen Bajonettverschluss mittels eines Ölfangbleches verbunden ist. Damit wird der Vorteil erreicht, dass zwischen Planetenträger bzw. Führungsscheibe des Planetenträgers und der benachbarten Stauscheibe eine axiale Verbindung ohne Axialspiel geschaffen wird. Das mit der Stauscheibe verbundene Ölfangblech zieht diese mittels der federnd ausgebildeten Bajonettverbindung spielfrei an den Planetenträger. Vorteilhaft ist ferner eine einfache Montage durch Strecken und Verdrehen.The The object of the invention is also characterized by the features of the sibling Claim 4 solved. According to the invention, it is provided that the adjacent baffle plate with the planet carrier by a bayonet lock by means of an oil catcher plate connected is. Thus, the advantage is achieved that between planet carrier or guide disc of the planet carrier and the adjacent baffle plate an axial connection without axial play is created. The oil collecting plate connected to the baffle plate pulls these by means of the spring-trained bayonet connection free of play to the planet carrier. Also advantageous is a simple assembly by stretching and Twisting.
Durch eine weitere vorteilhafte Ausgestaltung der Erfindung wird die Bajonettverbindung einerseits durch segmentförmig am Planetenträger angeordnete Rampen und radial vom Ölfangblech nach innen abragende elastische Zungen bewirkt. Darüber hinaus sind am Ölfangblech radial nach innen abragende Ringsegmente vorgesehen, welche in segmentförmige Einstiche an der Stauscheibe eingreifen. Damit wird der axiale Kraftfluss zwischen Stauscheibe und Planetenträger über das Ölfangblech hergestellt. Das Ölfangblech ist vorzugsweise einstückig spanlos als Blechformteil herstellbar.By A further advantageous embodiment of the invention is the bayonet connection on the one hand by segmental at the planet carrier arranged ramps and radially projecting from the oil collecting plate inwardly causes elastic tongues. Furthermore are on the oil collector provided radially inwardly projecting ring segments, which in segment-shaped recesses intervene at the baffle plate. This is the axial force flow made between the baffle plate and planet carrier on the oil catch plate. The oil collector is preferably in one piece without cutting produced as a sheet metal part.
In weiterer vorteilhafter Ausgestaltung der Erfindung sind am Ölfangblech und an der Stauscheibe Verriegelungselemente vorgesehen, welche ein Verdrehen der miteinander verbundenen Teile nach Erreichen der Endstellung verhindern.In Another advantageous embodiment of the invention are the oil collector and provided on the baffle plate locking elements, which a twisting of the interconnected parts after reaching the Prevent end position.
