Description
Die Erfindung betrifft eine Aufsitzkehrmaschine mit Heckmotor nach dem Oberbegriff des Patentanspruches 1. Eine derartige Aufsitzkehrmaschine ist beispielsweise mit dem Gegenstand der PCT/WO 97115731 bekannt geworden. Bei dieser bekannten Aufsitzkehrmaschine ist der Heckmotor stehend angeordnet und eine nach oben gerichtete Antriebswelle ist direkt an eine Gebläseturbine angeflanscht, welche über einen Saugschlauch, ein im Heckbereich angeordnetes Feinfilter beaufschlagt. Damit ist allerdings eine relativ ungünstige Gewichtsverteilung verbunden. Denn die im Heckbereich angeordnete Feinfifter-Entstaubung mit einem zugeordneten Absaugkanal, der in den Grobschmutzbehälter führt, macht das gesamte Fahrzeug hecklastig.The invention relates to a ride-on sweeper with a rear engine according to Preamble of claim 1. Such a ride-on sweeper is become known, for example, with the subject of PCT / WO 97115731. In this known ride-on sweeper, the rear motor is arranged upright and an upward drive shaft is directly on a blower turbine flanged, which is arranged in the rear area via a suction hose Fine filter applied. However, this is a relatively unfavorable one Weight distribution connected. Because the Feinfifter dedusting arranged in the rear area with an assigned suction channel that in the Coarse dirt container leads, makes the entire vehicle rear-heavy.
Darüber hinaus ist ein relativ hoher Aufbau des Fahrzeuges zu vergegenwärtigen, weil das ebenfalls stehend angeordnete Gebläse mit einem oben heraufgeführten Saugschlauch eine entsprechende Bauhöhe beansprucht.In addition, a relatively high construction of the vehicle is to be visualized, because the blower, which is also arranged upright, has a blower that comes up above Suction hose requires an appropriate height.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Aufsitzkehrmaschine der eingangs genannten Art so weiter zu bilden, daß sie bei geringerer Bauhöhe eine günstigere Gewichtsverteilung aufweist.The invention is therefore based on the object, a ride-on sweeper initially mentioned type so that they have a lower overall height has more favorable weight distribution.
Zur Lösung der gestellten Aufgabe ist der Erfindung durch die Merkmalskombination des Anspruches 1 gekennzeichnet.To achieve the object, the invention is through the combination of features of claim 1.
Wesentliches Merkmal der Erfindung ist, daß nun eine Filter-Gebläseeinheit vorgeschlagen wird, bei der das Feinfilter und die Gebläseturbine in einem gemeinsamen Kasten angeordnet sind und vertikal übereinander liegend im Bereich des Heckmotors vor der Hinterachse des Fahrzeuges angeordnet sind.An essential feature of the invention is that now a filter-blower unit is proposed in which the fine filter and the blower turbine in one common box are arranged and vertically one above the other in the Area of the rear engine are arranged in front of the rear axle of the vehicle.
Vorteil dieser Maßnahme ist also, daß durch die direkte Verbindung von Gebläseturbine Feinfilter in einem gemeinsamen Kasten, in den auch der Antrieb für die Gebläseturbine hineingeführt ist, ein gedrängter Aufbau gewährleistet ist. Wird dieser Anordnung noch in vertikaler Übereinander-Anordnung ausgebildet, gibt sich der weitere Vorteil, daß eine über dem Heckbereich des Fahrzeuges hinaus ragende Gewichtseinheit vermieden wird. Es ergibt sich damit die Möglichkeit, eine derartige vertikale Übereinander-Anordnung von Filter-Gebläseeinheit unmittelbar vor dem Heckmotor im Zwischenraum zwischen Vorder- und der Hinterachse anzuordnen.The advantage of this measure is that the direct connection of Blower turbine fine filter in a common box, in which also the drive for the fan turbine, a compact structure is guaranteed. If this arrangement is still formed in a vertical stacking arrangement, there is the further advantage that one over the rear area of the vehicle protruding weight unit is avoided. The result is Possibility of such a vertical stacking of filter-blower unit immediately in front of the rear engine in the space between To arrange front and rear axles.
Wird diese Fllter-Gebläseeinheit unmittelbar an dem Grobschmutzbehälter angeflanscht, ergibt sich der weitere Vorteil, daß ein ungünstiger Absaugkanal zwischen dem Feinfilter und dem Grobschmutzbehälter sowie ein Feinstaubbehälter entfallen kann. Insgesamt werden dadurch die Herstellungskosten des Fahrzeuges niedriger, bei gleichzeitiger Gewichtseinsparung und günstigerer Raumverteilung.This filter fan unit is attached directly to the coarse dirt container flanged, there is the further advantage that an unfavorable suction channel between the fine filter and the coarse dirt container as well as a Fine dust container can be omitted. Overall, the Manufacturing costs of the vehicle lower, while at the same time Weight saving and cheaper space distribution.
Der vom Feinfilter angesaugte Schmutz kann mittels einer Abreinigungsvorrichtung vom Feinfilter entfernt werden und fällt dann wieder in den Grobschmutzbehälter zurück.The dirt sucked in by the fine filter can be removed using a Cleaning device can be removed from the fine filter and then falls back into the coarse dirt container back.
Insgesamt ergibt sich auch ein niedriger, gedrängter Aufbau dadurch, daß der Heckmotor seine stehende Antriebswelle nach unten herausgeführt hat und von dort aus alle Antriebe für die verschiedenen anzutreibenden Organe abgeleitete werden.Overall, a low, compact structure results from the fact that the Rear engine has its standing drive shaft down and out there derived from all drives for the various organs to be driven become.
Eine nach oben herausgeführte, die Bauhöhe erhöhende Antriebswelle wird dadurch vermieden.A drive shaft that leads upwards and increases the overall height avoided.
Die Erfindung beansprucht noch eine weitere Ausführungsform als erfindungswesentlich, bei der ebenfalls die Aufgabe gelöst wird, ein möglichst gedrängter Aufbau mit niedriger Bauhöhe zu erreichen.The invention claims yet another embodiment as essential to the invention, in which the problem is also solved, one possible to achieve compact construction with a low overall height.
Kennzeichnend für diese Ausführungsform ist, daß die Feinstaubbehälter-Filter-Gebläseeinheit in horizontaler Hintereinander-Schaltung im Heckbereich des Fahrzeuges angeordnet ist und die Gebläseturbine mit dem Feinfilter und Feinstaubbehälter in einem gemeinsamen Kasten angeordnet sind. Insgesamt ergibt sich dadurch ein gedrängter Aufbau, weil Gebläseturbine Feinfilter und Feinstaubbehälter in einem gemeinsamen Kasten angeordnet sind. Es entfällt also ein beim Stand der Technik notwendiger Absaugschlauch zwischen einer entfernt, vom Feinfilter angeordneten Gebläseturbine.It is characteristic of this embodiment that the fine dust container filter / blower unit in a horizontal connection in the rear area of the Vehicle is arranged and the blower turbine with the fine filter and Fine dust containers are arranged in a common box. All in all This results in a compact structure because the fine filter and fan turbine Fine dust containers are arranged in a common box. It does not apply that is, a suction hose necessary in the prior art between one removed, fan turbine arranged from the fine filter.
Zwar ist die Feinstaubbehälte-Filter-Gebläseeinheit im Heckbereich des Fahrzeuges angeordnet; es ist aber vorgesehen, daß der Heckmotor nicht über der Hinterachse liegt, sondern etwas vor der Hinterachse, um eine möglichst gewichtsgünstige Gewichtsverteilung auf die Hinterachse zu ermöglichen.The fine dust container filter blower unit is in the rear area of the Arranged vehicle; but it is provided that the rear engine does not have the rear axle, but something in front of the rear axle in order to get one to allow weight-favorable weight distribution on the rear axle.
Ein gedrängter Aufbau ergibt sich bei dieser Ausführungsform auch dadurch, daß der Antrieb für die Gebläseturbine im Zwischenraum zwischen der Gebläseturbine und dem Feinfilter und Feinstaubbehälter über eine Riemenscheibe erfolgt, die über einen Winkeltrieb mit der hängenden Antriebswelle des Heckmotors verbunden ist.A compact structure also results in this embodiment in that the drive for the blower turbine in the space between the blower turbine and the fine filter and fine dust container via a pulley, which via an angular drive with the hanging drive shaft of the rear engine connected is.
Der Erfindungsgegenstand der vorliegenden Erfindung ergibt sich nicht nur aus dem Gegenstand der einzelnen Patentansprüche, sondern auch aus der Kombination der einzelnen Patentansprüche untereinander.The subject matter of the present invention does not only result from the subject of the individual claims, but also from the Combination of the individual claims.

Die Aufsitzkehrmaschine nach Figur 1 besteht aus einem Fahrgestell mit einer
Vorderachse 3 und einer Hinterachse 4, wobei im Bereich etwa vor der
Hinterachse ein Heckmotor ein angeordnet ist. Er weist eine hängende
Antriebswelle auf, die auf einen Winkeltrieb 8 arbeitet, von dem aus der
Fahrantrieb über ein weiteres Winkelgetriebe 17 auf der Hinterachse 4 abgeleitet
ist. Vom Winkeltrieb 8 ist im übrigen ein Riementrieb zwei abgeleitet, der zum
Antrieb einer Gebläseturbine 10 und ferner zum Antrieb der Kehrwalze 5 und der
Seitenbesen 15 geeignet ist. The ride-on sweeper according to Figure 1 consists of a chassis with a

Grobschmutzbehälter 6, der zwischen Vorder- und Hinterachse 3,4 angeordnet
ist. Aus diesem Behälter wird der entstehende Feinstaub direkt nach oben
abgesaugt, weil an dem Grobschmutzbehälter 6 unmittelbar ein Feinfilter 11
angeflanscht ist, der ist demzufolge mit seiner gesamten Oberfläche unmittelbar
Teil des Deckelbereiches des Grobschmutzbehälters 6 ist. Hieraus ergibt sich
eine außerordentliche wirksame Staubabscheidung.The counter-clockwise sweeper roller 5 conveys the

zugeordnet ist, die es gestattet, den Feinfilter von Zeit zu Zeit abzureinigen.It is not shown that the
Wichtig ist, daß die Gebläseturbine 10 und der Feinfilter in einem gemeinsamen,
die beiden Aggregate umschließenden Kasten 24 angeordnet sind, so daß sich
ein gedrängter, raumsparender Aufbau ergibt. Die Riemenscheibe 18 für den
Antrieb der Gebläseturbine 10 ist deshalb im Zwischenraum 13 zwischen den
beiden Aggregaten angeordnet.It is important that the
In Figur 2 ist eine gegenüber Figur 1 abgewandelte Ausführungsform dargestellt,

jedoch in Heckbereich des Fahrzeuges liegend angeordnet ist. Der Antrieb der
Gebläseturbine 10 erfolgt wiederum über eine Riemenscheibe 18, die im
Zwischenraum 23 zwischen den beiden Aggregaten 10,11 angeordnet ist. Die
Riemenscheibe 18 wird von einer untenliegenden Riemenscheibe 21 angetrieben,
die drehfest mit einer Antriebswelle 20 verbunden ist, die in ein Zwischengetriebe
16 hineingeführt ist, welches von dem Heckmotor 1 angetrieben ist. FIG. 2 shows an embodiment modified compared to FIG. 1,
