Description

Die Erfindung betrifft ein leistungsstarkes (25KW) Miniraupenfahrzeug Bit hydrostatischem Antrieb.The invention relates to a powerful (25KW) mini-crawler vehicle with hydrostatic drive.

Es dient als Träger- und Antriebsfahrzeug hydraulisch betriebener Anbaugeräte und Werkzeuge besonders im Forst&igr; ie Weinbau, in der Landschaftspflege, in der Landwirtschaft, in kommunalem Bereich und auf Baustellen. It serves as a carrier and drive vehicle for hydraulically operated attachments and tools, particularly in forestry, viticulture, landscape maintenance, agriculture, in the municipal sector and on construction sites.

Durch folgende technische und konstruktive Merkmale unterscheidet sich die Erfindung von heute üblichen Antriebs- und Trägerfahrzeugen in oben genannten Bereichen :The following technical and design features distinguish the invention from today’s conventional drive and carrier vehicles in the above-mentioned areas:

1.Da de· 25KH-starken Verbrennungsmotor (1) in direktem Kraftschluß mehrere Hydraulikpumpen (4) an die Kurbelwelle geflanscht wurde, stehen den Pumpen
nahezu lOOX der Motorleistung zur Verfügung, während herkömmliche Schlepper im Forst, Weinbau, Landwirtschaft... durch ihre großdimensionierten Getriebe mit Zapfwellenausgang für externe Anbaugeräte hier schon erste Energieverluste (bis zu ISX) haben.
1.Since the 25KH combustion engine (1) has several hydraulic pumps (4) flanged to the crankshaft in direct power connection, the pumps
almost lOOX of the engine power is available, while conventional tractors in forestry, viticulture, agriculture... have initial energy losses (up to ISX) due to their large-dimensioned gearboxes with PTO output for external attachments.

Daraus folgt, daß in der Praxis ein mindestens 30Kw-starker Schlepper herkömmlicher Technik nötig wäre, um das Gerät anzutreiben, welches das
Miniraupenfahrzeug mit 25KW antreibt.
This means that in practice a tractor with at least 30 kW of conventional technology would be necessary to drive the device, which
Mini crawler vehicle powered by 25KW.

2.Die hier ausschließlich verwendete hydraulische Steuerung und Kraftübertragung (Hydraulikschläuche) an externe Anbaugeräte ist im Vergleich zu
herkömmlicher mechanischen Steuerung oder Kraftübertragung mittels drehender Gelenkwelle wesentlich unfallsicherer (keine beweglichen Teile) und durch die eingebauten geschlossenen Überdruckventile deutlich verschleißärmer (keine Abreißbolzen, Rutschkupplungen, o.a.) .
2.The exclusively used hydraulic control and power transmission (hydraulic hoses) to external attachments is compared to
Compared to conventional mechanical control or power transmission by means of a rotating universal joint shaft, it is much safer in the event of accidents (no moving parts) and, thanks to the built-in closed pressure relief valves, it is significantly less prone to wear (no shear bolts, slip clutches, etc.).

3.Durch den Kraftschluß ia geschlossenen Hydrauliksystem (kein kontakt Bit
Hasser oder Staub) ist das gesamte Fahrzeug Bit seinen Anbaugeräten wesentlich wartungsfreundlicher als bei mechanischer Kraftübertragung.
3.Due to the force connection ia closed hydraulic system (no contact bit
Hater or dust), the entire vehicle and its attachments are much easier to maintain than with mechanical power transmission.

4.Durch eine angetriebene Aufstandsfläche (Gummiraupen) von 8 300c«2bei eine· Eigengewicht von nur 900kp (herkömmliche Schlepper oder Raupen «it
vergleichbarer Abgabeleistung wiegen 2-3mal so viel)distanziert die neue
Erfindung herkömmliche Raupen- oder Radfahrzeuge vergleichbarer Abgabeleistung und Baugröße (Mini- oder Schmalspurfahrzeuge) auf de· Gebiet der Geländetauglichkeit und Steigfähigkeit auf natürlichen Untergründen deutlich.
4.With a driven contact area (rubber tracks) of 8 300c« 2 with a dead weight of only 900kp (conventional tractors or tracks «it
comparable power output weigh 2-3 times as much) the new
Invention of conventional tracked or wheeled vehicles with comparable output and size (mini or narrow-track vehicles) in the field of off-road capability and climbing ability on natural surfaces.

S.Durch die ausschließliche Nutzung des selbsttragenden Fahrzeugrahmens (5) al 8 Hydrauliköl- und Kraftstoffreservoir konnte eine bisher unter vergleichbaren Geräten nicht erreichte Kompaktbauweise hergestellt werden.S.By exclusively using the self-supporting vehicle frame (5) as the hydraulic oil and fuel reservoir, a compact design was achieved that had not previously been achieved with comparable devices.

6.Die Verwendung zweier armierter Gummiketten (3) mit einem Umlenkradius von nur 7cm ermöglicht ein extrem flaches Fahrwerk mit zwei je 38cm breiten Gummiketten, was unter Anderem zu einem extrem niedrigen Fahzeugschwerpunkt (2) von weniger als 45cm über dem Boden führte.6.The use of two reinforced rubber tracks (3) with a deflection radius of only 7cm enables an extremely flat chassis with two 38cm wide rubber tracks, which, among other things, led to an extremely low vehicle center of gravity (2) of less than 45cm above the ground.

24 Stützrollen (6) verteilen das Eigengewicht auf die beiden Raupenbänder, wobei die 16 Pendelachsen (7) die nötige Beweglichkeit und Traktion im gelände ermöglichen.24 support rollers (6) distribute the weight across the two crawler tracks, while the 16 pendulum axles (7) provide the necessary mobility and traction on the terrain.

Insbesondere die Merkmale unter 5.und 6. haben gegenüber relativ hochbeinigen Rad- oder Kettenfahrzeugen den Vorteil, daß es in der Praxis nicht mehr so leicht zu dem gefährlichen "Aufbäumeffekt" in steilem Gelände kommt.In particular, the features under 5. and 6. have the advantage over relatively long-legged wheeled or tracked vehicles that in practice the dangerous "rearing effect" on steep terrain no longer occurs so easily.

Der relativ breite, ungefederte Aufstand mit diesem extrem niedrigen Schwerpunkt gewährleistet einen wesentlich stabileren Stand, als beispielsweise luftbereifte Schmalspurschlepper.The relatively wide, unsprung base with this extremely low center of gravity ensures a much more stable position than, for example, narrow-track tractors with pneumatic tires.

7.Die bereits unter 4. erwähnte überdimensionale Aufstandsfläche entspricht voll den Forderungen, die heute an in freier Natur fahrende Fahrzeuge gestellt werden (bes.im Forst,Weinbau,Kulturen und Landschaftspflege) . Mit einem Bodendruck von nur 110g/cm2 hinterläßt die Miniraupe einen Bodendruck, der deutlich geringer ist, als der, eines menschlichen Fußabdruckes (ca.300g/cm2) .7.The oversized contact area mentioned under 4. fully meets the requirements that are placed on vehicles driving in the open air today (especially in forestry, viticulture, crops and landscape maintenance). With a ground pressure of only 110g/cm 2 , the mini-caterpillar leaves a ground pressure that is significantly lower than that of a human footprint (approx. 300g/cm 2 ).

Dieses Merkmal schließt die unbeliebten, weil schwer reversiblen, Bodenverdichtungen aus.This feature eliminates soil compaction, which is unpopular because it is difficult to reverse.
