Description

Aufsitzkehrmaschine mit Heckmotor Ride-on sweeper with rear engine
Die Erfindung betrifft eine Aufsitzkehrmaschine mit Heckmotor nach dem Oberbegriff des Patentanspruches 1. Eine derartige Aufsitzkehrmaschine ist beispielsweise mit dem Gegenstand der PCT/WO 97/15731 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 ungünstigeThe invention relates to a ride-on sweeper with a rear motor according to the preamble of claim 1. Such a ride-on sweeper has become known, for example, with the subject of PCT / WO 97/15731. In this known ride-on sweeper, the rear motor is arranged upright and an upward drive shaft is flanged directly to a blower turbine, which acts on a fine filter arranged in the rear area via a suction hose. However, this is a relatively unfavorable one
Gewichtsverteilung verbunden. Denn die im Heckbereich angeordnete Feinfilter- Entstaubung mit einem zugeordneten Absaugkanal, der in den Grobschmutzbehälter führt, macht das gesamte Fahrzeug hecklastig.Weight distribution connected. Because the fine filter dedusting arranged in the rear area with an assigned suction channel, which leads into the coarse dirt container, 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 structure of the vehicle is to be visualized because the blower, which is also arranged upright, with a suction hose brought up at the top, requires a corresponding overall 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 of developing a ride-on sweeper of the type mentioned at the outset such that it has a more favorable weight distribution with a lower overall height.
Zur Lösung der gestellten Aufgabe ist der Erfindung durch die technische Lehre des Anspruches 1 gekennzeichnet.To achieve the object, the invention is characterized by the technical teaching 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 a filter-blower unit is now proposed in which the fine filter and the blower turbine are arranged in a common box and are arranged vertically one above the other in the area of the rear engine 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 the blower turbine fine filter in a common box, into which the drive for the blower turbine is also guided, ensures a compact structure. If this arrangement is still formed in a vertical stacking arrangement, there is the further advantage that a weight unit protruding beyond the rear region of the vehicle is avoided. This results in the possibility of such a vertical stacking of filter Position blower unit directly in front of the rear engine in the space between the front and rear axles.
Wird diese Filter-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.If this filter-blower unit is flanged directly to the coarse dirt container, there is the further advantage that an unfavorable suction channel between the fine filter and the coarse dirt container and a fine dust container can be dispensed with. Overall, the manufacturing costs of the vehicle are lower, while at the same time saving weight and more favorable 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 from the fine filter using a cleaning device and then falls back into the coarse dirt container.
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, there is also a low, compact structure in that the rear engine has its stationary drive shaft led downwards and from there all drives for the various organs to be driven are derived.
Eine nach oben herausgeführte, die Bauhöhe erhöhende Antriebswelle wird dadurch vermieden.A drive shaft leading upwards and increasing the overall height is thereby 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 a further embodiment as essential to the invention, in which the object is also achieved to achieve a structure that is as compact as possible and has 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 is arranged in a horizontal connection in series in the rear area of the vehicle and the blower turbine with the fine filter and fine dust container are arranged in a common box. Overall, this results in a compact structure because the fan turbine fine filter and fine dust container are arranged in a common box. There is therefore no need for a suction hose, which is necessary in the prior art, between a fan turbine which is removed and arranged by 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 filter blower unit is arranged in the rear area of the vehicle; but it is provided that the rear engine does not have the rear axle, but slightly in front of the rear axle in order to enable weight distribution to the rear axle that is as favorable as possible.
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 results in this embodiment also in that the drive for the blower turbine takes place in the space between the blower turbine and the fine filter and fine dust container via a belt pulley which is connected via an angular drive to the hanging drive shaft of the rear engine.
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 results not only from the subject matter of the individual patent claims, but also from the combination of the individual patent claims with one another.
Alle in den Unterlagen, einschließlich der Zusammenfassung, offenbarten Angaben und Merkmaie, insbesondere die in den Zeichnungen dargestellte räumliche Ausbildung werden als erfindungswesentlich beansprucht, soweit sie einzeln oder in Kombination gegenüber dem Stand der Technik neu sind.All of the information and features disclosed in the documents, including the summary, in particular the spatial design shown in the drawings, are claimed to be essential to the invention insofar as they are new to the prior art, individually or in combination.
Im folgenden wird die Erfindung anhand von mehrere Ausführungswege darstellenden Zeichnungen näher erläutert. Hierbei gehen aus den Zeichnungen und ihrer Beschreibung weitere erfindungswesentliche Merkmale und Vorteile der Erfindung hervor.In the following, the invention will be explained in more detail with reference to drawings showing several possible embodiments. Here, from the drawings and their description, further features and advantages of the invention that are essential to the invention emerge.

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. Die Seitenbesen 15 werden hierbei durch einen eigenen Riementrieb 14 angetrieben, der von dem Winkeltrieb 8 abgeleitet ist.The ride-on sweeper according to FIG. 1 consists of a chassis with a front axle 3 and a rear axle 4, a rear engine being arranged in the area approximately in front of the rear axle. It has a hanging drive shaft which works on an angular drive 8, from which the travel drive is derived via a further angular gear 17 on the rear axle 4. A belt drive two is derived from the angle drive 8, which is suitable for driving a blower turbine 10 and also for driving the sweeping roller 5 and the side brush 15. The side brushes 15 are driven by their own belt drive 14, which is derived from the angle drive 8.
Die gegen den Uhrzeigersinn angetriebene Kehrwalze 5 befördert den aufgenommenen Schmutz nach dem Überwurfprinzip in einenThe sweeping roller 5, which is driven counterclockwise, transports the dirt picked up into one according to the throwing principle
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.Coarse dirt container 6, which is arranged between the front and rear axles 3, 4. The resulting fine dust is suctioned off upward directly from this container because a fine filter 11 is flanged directly onto the coarse dirt container 6, which is consequently, with its entire surface, directly part of the lid area of the coarse dirt container 6. This results in an extraordinarily effective dust separation.
In Ausströmrichtung hinter dem Feinfilter 11 ist ein Antrieb mit einer Riemenscheibe 18 für die Antriebswelle 9 der Gebläseturbine 10 angeordnet. Die Gebläseturbine 10 ist damit in Ausströmrichtung hinter dem Feinfilter 11 angeordnet. Die Antriebswelle 9 ist einseitig hängend in zwei hintereinander liegenden Lagern 7,7a gelagert.A drive with a pulley 18 for the drive shaft 9 of the blower turbine 10 is arranged in the outflow direction behind the fine filter 11. The blower turbine 10 is thus arranged behind the fine filter 11 in the outflow direction. The drive shaft 9 is suspended on one side in two successive bearings 7, 7 a.
Der Grobschmutzbehälter 6 ist im übrigen als Schublade 19 ausgebildet, der senkrecht zur Zeichenebene nach Figur 1 herausziehbar und hereinschiebbar ist.The coarse dirt container 6 is also designed as a drawer 19 which can be pulled out and pushed in perpendicular to the plane of the drawing according to FIG.
Es ist nicht dargestellt, daß dem Feinfilter 11 eine Abreinigungsvorrichtung zugeordnet ist, die es gestattet, den Feinfilter von Zeit zu Zeit abzureinigen.It is not shown that the fine filter 11 is associated with a cleaning device which allows the fine filter to be cleaned from time to time.
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 fan turbine 10 and the fine filter are arranged in a common box 24 enclosing the two units, so that there is a compact, space-saving construction. The pulley 18 for driving the blower turbine 10 is therefore arranged in the space 13 between the two units.
In Figur 2 ist eine gegenüber Figur 1 abgewandelte Ausführungsform dargestellt, bei dem ebenfalls ein Heckmotor eine Filter-Gebläseeinheit 10,11 antreibt, die 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. DieFIG. 2 shows an embodiment that is modified compared to FIG. 1, in which a rear engine likewise drives a filter-blower unit 10, 11, which, however, is arranged lying in the rear area of the vehicle. The blower turbine 10 is in turn driven by a pulley 18 which is arranged in the space 23 between the two units 10, 11. The
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. Es versteht sich von selbst, daß der vorher erwähnte Winkeltrieb 8 des Heckmotors 1 auch mit dem Zwischengetriebe 16 zusammengefaßt werden kann.Pulley 18 is driven by an underlying pulley 21 which is connected in a rotationally fixed manner to a drive shaft 20 which is guided into an intermediate gear 16 which is driven by the rear motor 1. It goes without saying that the aforementioned angular drive 8 of the rear motor 1 can also be combined with the intermediate gear 16.
Diese Ausführungform ist wiederum wesentlich, da der Feinfilter 11 und die Gebläseturbine 10 in einem gemeinsamen Kasten 24 angeordnet sind.This embodiment is again essential since the fine filter 11 and the blower turbine 10 are arranged in a common box 24.
Der niedrige Aufbau des Gesamtfahrzeuges ergibt sich im übrigen aus Figur 1 , aus der erkennbar ist, daß eine Abdeckung 22 in niedriger Höhe über alle im Bereich zwischen Vorder- und Hinterachse zusammengefaßten Aggregate 1 ,10,11 geführt werden kann.The low construction of the overall vehicle is shown in FIG. 1, from which it can be seen that a cover 22 can be guided at a low height over all units 1, 10, 11 combined in the area between the front and rear axles.
Gleiches ergibt sich aus der Figur 2, aus der ebenfalls ein relativ niedriger Aufbau dadurch erreicht wird, daß auf eine nach oben herausgeführte Antriebswelle des Heckmotors verzichtet wird, welche die Bauhöhe erhöhen würde. The same results from FIG. 2, from which a relatively low structure is also achieved by dispensing with an upward drive shaft of the rear engine, which would increase the overall height.
