Description
Hydrostatisch-mechanisches Getriebe Die Erfindung bezieht sich auf ein hydrostatischmechanisches Getriebe, bestehend aus einer hydrostatischen Pumpe und einem von dieser gespeisten hydrostatischen Antrieb sowie einem Stirnräderplanetengetriebe, bei dem das Zentralrad mit der die Pumpe antreibenden Kraftmaschine und die getriebene Welle mit dem Planetenträger verbunden ist, ferner das Hohlrad einen zusätzlichen Außenzahnkranz trägt, mit dem ein auf der Welle des hydrostatischen Antriebes sitzendes Ritzel kämmt.Hydrostatic-mechanical transmission The invention relates to a hydrostatic mechanical transmission consisting of a hydrostatic pump and a hydrostatic drive fed by this and a spur planetary gear, in which the central wheel with the engine driving the pump and the driven one Shaft is connected to the planet carrier, furthermore the ring gear an additional External ring gear carries, with which a seated on the shaft of the hydrostatic drive Pinion combs.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, bei einem Getriebe dieser Gattung die Zahndrücke am höchstbelasteten Zahnkranz gering zu halten und somit eine leichte Bauweise dieses Radkranzes und seiner Lagerung zu ermöglichen.The object of the invention is, in a Gear of this type to keep the tooth pressures on the most heavily loaded sprocket low and thus to enable a lightweight construction of this wheel rim and its storage.
Diese Aufgabe wird dadurch gelöst, daß a) die Innenverzahnung und die Außenverzahnung des Hohlrades (60) in bekannter Weise in derselben radialen Ebene liegen, b) mit der Außenverzahnung des Hohlrades in bekannter Weise mehrere am Umfang verteilte Ritzel, die auf den Antriebswellen von hydrostatischen Motoren sitzen, die von der Pumpe gemeinsam gespeist werden und zweckmäßig auf gleiche Übersetzungsverhältnisse eingestellt sind, kämmen.This object is achieved in that a) the internal teeth and the external toothing of the ring gear (60) in a known manner in the same radial Lie level, b) several with the external toothing of the ring gear in a known manner Circumferentially distributed pinions on the drive shafts of hydrostatic motors sit that are fed jointly by the pump and expediently on the same gear ratios are set, comb.
Es ist bereits bekannt, bei einem aus Hohlrad, mehreren Planetenrädern und einem Zentralrad bestehenden Umlaufrädergetriebe am Hohlrad eine Innen- und eine Außenverzahnung anzubringen, die beide in derselben radialen Ebene liegen. Dabei käm.°nt mit dem Außenzahnkranz ein auf der Welle einer hydrostatischen Einheit sitzendes Ritzel.It is already known in the case of a ring gear, several planet gears and a central gear existing epicyclic gear on the ring gear an internal and to attach an external toothing, both of which lie in the same radial plane. The external gear rim meshes with the shaft of a hydrostatic unit seated pinion.
Weiterhin ist es bekannt, einen außen verzahnten Radkranz durch mehrere an seinem Umfang verteilte Ritzel anzutreiben, die auf den Wellen von hydrostatischen Motoren sitzen, die zweckmäßig auf das gleiche Übersetzungsverhältnis eingestellt sind und von einer hydrostatischen Pumpe gespeist werden.Furthermore, it is known to have an externally toothed wheel rim by several to drive pinions distributed on its periphery, which on the shafts of hydrostatic Motors sit, which are expediently set to the same gear ratio and are fed by a hydrostatic pump.
Die A b b. 1. zeigt in einem Längsschnitt durch das Gehäuse ein hydrostatisch-mechanisches Getriebe. Die Hohlwelle 17 eines Elektromotors weist an ihrem einen Ende eine Innenverzahnung auf, die mit der Vielkeilwelle 65 des Zentralrades 62 eines UmAaufrädergetriebes drehfest verbunden ist. Die Welle 65 ist mit einem Führungsring 66 verbunden, der im Innern der Hohlwelle 17 längsbeweglich zentriert ist und mit der Welle 10 einer hydrostatischen Pumpe B 1. zusammenhängt. Die Pumpe kann durch Schwenken ihres Gehäuses auf Vor- und Rückwärtsförderung sowie auf Nullförderung eingestellt werden. Über die Leitungen 63 ist die Pumpe mit den Ölmotoren B 2 verbunden. In der Regel sind drei Ölmotoren gemäß' A b b. 2 angeordnet, auf deren Wellen Ritzel sitzen, die gemeinsam in die Außenverzahnung des Zahnrades 60 eingreifen. Die Ölmotoren geben etwa gleiche Drehmomente ab, so daß ihre Antriebskräfte an mehreren am Umfang verteilten Stellen angreifen und das Zahnrad 60 nur geringen exzentrischen Kräften unterworfen sind. Sollte eine zusätzliche Zentrierung nötig sein, so kann diese fliegend in einem verhältnismäßig kleinen Lager erfolgen, das beispielsweise konzentrisch um die mit dem Planetenradträger verbundene Abtriebswelle angeordnet ist. Dadurch wird der innen- und außenverzahnte Radkranz so gleichmäßig beansprucht, daß ein Verziehen desselben ausgeschlossen ist, und der mehrfache Zahneingriff bei der Innen- und Außenverzahnung ergibt eine günstige Ausnutzung der Leistungsfähigkeit dieses Zahnrades 60. Bei einer Umkehr der Kraftübertragungsrichtung arbeiten die hydrostatischen Motoren B 2 in bekannter Weise als Pumpen.The A b b. 1. shows a hydrostatic-mechanical system in a longitudinal section through the housing Transmission. The hollow shaft 17 of an electric motor has internal teeth at one end on that with the splined shaft 65 of the central wheel 62 of a UmAaufradgetriebes is rotatably connected. The shaft 65 is connected to a guide ring 66, the is centered in the interior of the hollow shaft 17 longitudinally movable and with the shaft 10 one hydrostatic pump B 1. related. The pump can be rotated by swiveling its housing can be set to forward and backward conveyance as well as to zero conveyance. Above the lines 63, the pump is connected to the oil motors B 2. Usually are three oil motors according to 'A b b. 2 arranged, on the shafts of which pinions sit together engage in the external teeth of the gear 60. The oil engines give about the same Torques from so that their driving forces at several points distributed around the circumference attack and the gear 60 are only subjected to low eccentric forces. If additional centering is necessary, this can be carried out in one relatively small camp done, for example, concentrically around the with the output shaft connected to the planetary gear carrier is arranged. This will make the internally and externally toothed wheel rim so evenly stressed that distortion the same is excluded, and the multiple meshing of the internal and external External toothing results in a favorable utilization of the performance of this gear 60. When the direction of force transmission is reversed, the hydrostatic ones work Motors B 2 in a known manner as pumps.
