Description

Übersetzungsgetriebe für mit gleichachsigen Elektromotoren .auszurüstende Fahrzeuge, insbesondere FlurfÖrdergeräte Bei elektrischen Flurfördergeräten, insbesonaere Uabelstaplern, ist es bekannt , gleichachsige Antriebs-Elektromotoren zu verwenden. Dabei ist jeder Antriebsinotor auf der dem zugehörigen Antriebsrad zugewendeten Seite eines auf der Innenseite des Rades angeordneten Ubersetzungsgetriebes derart untergebracht, daß ein Xraftfluss vom Antriebsmotor zum Fahrzeugrad getrennt auf jeder Seite Z-förmig von innen nach außen erfolgt. Solche Anordnungen sind insofern unvorteilhaft, als die Motoren und insbesondere deren :Nollektoren, die der Wartung bedürfen, verhältnismäßig schwer zugänglich sind. Zweck der Erfindung, ist es hauptsächlich, diesem Nachteil abzuhelfen.Transmission gear for vehicles to be equipped with equiaxed electric motors, in particular FlurfÖrdergeräte In electric floor conveyors, especially Uabelstaplern, it is known to use coaxial drive electric motors. Each drive motor is housed on the side facing the associated drive wheel of a transmission gear arranged on the inside of the wheel in such a way that a power flow from the drive motor to the vehicle wheel takes place separately on each side in a Z-shape from the inside to the outside. Such arrangements are disadvantageous in that the motors, and in particular their collectors, which require maintenance, are relatively difficult to access. The main purpose of the invention is to remedy this disadvantage.

Ein weiterer Zweck der Erfindune besteht darin, den Schwerpunkt der Gesamtanordnung weiter nach hinten und außen verlagern zu können, was insbesondere bei kurzgebauten Flurfördergeräten wie Gabelstaplern wichtig ist, um au:e diese Weise deren Standsicherheit zu erhöhen.Another purpose of the invention is to focus the To be able to shift the overall arrangement further back and forth, which in particular in the case of short-built forklifts such as forklifts, it is important to remove them Way to increase their stability.

Erfindungsgemäß sind in einem symmetrisch zur senkreenten Längsmittelebene des Fahrzeugs anzuordnenden Lietriebegehäuse zwei voneinander unabhängige, vollständige Getriebe angeordnet; Das Getriebegehäuse ist auf beiden Seiten mit je einem zur Antriebswelle und zur Abtriebswelle konzentrischen Flansch zum Ansetzen der Motoren und der iichshälften oaer ggf. Achshülsen, die zugleich Portalachsen tragen können, versehen, derart, daß ein Kraftfluss vom Antriebsmotor zum Fahrzeugrad auf jeder Seite getrennt U-förmig von außen nach innen zur Fahrzeugmitte über den Rüdersatz in Fahrzeuglängsrichtung und wieder von innen nach außen erfolgt. Dadurch wird erreicht, daß die Motoren an ihrer Kollektorseite von außen her, etwa kurz hinter dem Schutzblech des Antriebsrades, leicht zugänglich sind und der Massenschwerpunkt des Antriebes von der Achse weg verlagert wird, so daß die'Standsicherheit des Fahrzeugs erhöht wird. Für die zwischen dem Getriebegehäuse und dem Antriebsrad jeweils erforderlichen Achshälften oder Achshülsen, welche sogenannte Portalachsen tragen können, lassen sich bei einer solchen Anordnung in einfacher Weise dieselben Konstruktionsteile verwenden, wie sie auch bei mit Verbrennungsmotoren als t\jitrieb verselienen Fahrzeugen sonst gleicher Art benutzt werden.According to the invention two independent, complete transmissions are arranged in a symmetrical to the perpendicular longitudinal center plane of the vehicle to be arranged transmission housing; The gearbox is each provided on both sides with a concentric to the drive shaft and the output shaft flange for attachment of motors and iichshälften OAER optionally axle sleeves that can simultaneously carry portal axles, such that a force flow from the drive motor isolated from the vehicle wheel on each side U -shaped from the outside to the inside to the center of the vehicle via the rear set in the vehicle longitudinal direction and again from the inside to the outside. This ensures that the motors are easily accessible on their collector side from the outside, for example just behind the protective plate of the drive wheel, and the center of gravity of the drive is shifted away from the axle, so that the stability of the vehicle is increased. For the axle halves or axle sleeves required between the gear housing and the drive wheel, which can carry so-called portal axles, the same structural parts can be used in a simple manner in such an arrangement as are otherwise used in vehicles equipped with internal combustion engines as drive units .

Im folgenden ist die Erfindung anhand der Zeichnung beispielsweise näher erläutert: Die Figur zeigt im Grundriss schematisch das-Übersetzungsgetriebe eines Fahrzeugs der zur Rede stehenden Arb.The invention is exemplified below with reference to the drawing explained in more detail: The figure shows schematically the transmission gear in plan a vehicle of the Arb in question.

i ist das zu der strichpunktiert angedeuteten Längsmittelebene des Fanrzeugs symmetrisch ausgebildete Getriebegehäuse. Dieses enthält rechts unü links von der Längsmittelebene je ein vollständiges Übersetzungsgetriebe mit den (im einzelnen nicht dargestellten) Zahnrädern, weiche je einen durch Pfeile veranschaulichten Kraftfluss bilden. Seitlich an dem Gehäuse sind konzentrisch zur Antriebswelle 2 bzw. 2t je ein Flansch 3, 4 bzw. 3t, 41 vorgesehen. An den Flansch 3 bzw. 3' ist je ein Antriebsmotor 5 ansetzbar, an den Flansch 4 bzw 41 kann je eine Achshälfte 6 angesetzt werden. 1)iese kann entweder ein einfacher Achstrichter sein, wenn das Antriebsrad des Fahrzeugs koaxial zur Ausgangswelle des Getriebes angeordnet ist, oder aber die Achshälfte kann aus einer Hülse und einem Portalstück, welches ein zusätzliches Zahnradpäar enthält, bzw. einem Gehäuse bestehen.i is the gear housing designed symmetrically to the longitudinal center plane of the fan tool, indicated by dash-dotted lines. This contains the right New York Convention left of the longitudinal center plane each a complete transmission gear with the (not shown in detail) gears, each form a soft illustrated by arrows power flow. On the side of the housing, a flange 3, 4 or 3t, 41 is provided concentrically to the drive shaft 2 or 2t. A drive motor 5 can be attached to each flange 3 or 3 ' , and an axle half 6 can be attached to each of the flanges 4 or 41. 1) This can either be a simple axle funnel if the drive wheel of the vehicle is arranged coaxially to the output shaft of the transmission, or the axle half can consist of a sleeve and a portal piece, which contains an additional pair of gears, or a housing.

Bei einer solchen Anordnung ist der Motor 5 von der Seite her, neben dem Antriebsrad bzw. hinter dessen Schutzblech 8 leicht zugänglich. Außerdem wird der Schwerpunkt von der Antriebsachse weg nach hinten verlagert.With such an arrangement, the motor 5 is easily accessible from the side, next to the drive wheel or behind its fender 8. In addition, the center of gravity is shifted backwards away from the drive axle.
