Abstract

The control of the rear axle can be switched off automatically and mechanically locked when engaging a high gear. A lever is provided which works in conjunction with a tension rope and a bar of the drive. A tension rope and a spring are coupled to a rocker and a locking bolt is held in a guide. In the current circuit of the magnetic valve a switch is provided for the all wheel drive to break the current circuit and switch to four wheel drive. The machine can be used for e.g. cleaning, distribution or as a snow plough.

Description

4-Rad gelenkte z.B.selbstaufnehmende,saugende Kehrmaschine.4-wheel steered e.g. self-picking, suction sweeper.

Die Erfindung betrifft ein kommunal-Fahrgestell zum Ausbau von Strassenreinigungsgerätenwie selbstaufnehmende,saugende Kehrmaschnnen,4-radgelenkt mit volhydraulischem Motor auf mechanischer Schaltachse zum Antrieb der Aggregate und des Fahrbetriebes.The invention relates to a municipal chassis for the expansion of street cleaning devices such as Self-absorbing, suction sweepers, 4-wheel steered with fully hydraulic motor on mechanical switching axis to drive the units and drive operation.

Die Erfindung besteht in der automatischen Verriegelung der gelenkten Hinterachse.Bei Transport und Leerfahrten wird die Geschwindigkeit der Maschine,wie bei jedem normalen Kraftfahrzeug durch Betätigung des Gaspedals reguliert.The invention consists in the automatic locking of the steered The speed of the machine, like regulated in every normal motor vehicle by pressing the accelerator pedal.

4-Rad gelenkte Maschinen dürfen bei höheren Geschwindigkeiten nur vorderradgelenkt,auf öffentlichen Strassen,gefahren werden.4-wheel steered machines are only allowed at higher speeds front-wheel steered on public roads.

Daher muss die Lenkung der Hinterachse abgeschaltet werden,und mechanisch verriegelbar sein.Bekannter Weise erfolgt diese mechanische Verriegelung manuell durch Einstecken von Bolzen.-Erfindungsgemäss erfolgt diese Verriegelung nunmehr automatisch, beim Einlegen des Schnellgangs.Ausserdem wird gleichzeitig der Stromkreis zur elektrischen Einschaltung der 4-Rad-Lenkung automatisch unterbrochen.Therefore the steering of the rear axle has to be switched off, and mechanically As is known, this mechanical locking is done manually by inserting bolts. According to the invention, this locking now takes place automatically when the overdrive is engaged, and the circuit is activated at the same time automatically interrupted for the electrical activation of the 4-wheel steering.

Weiter besteht die Erfindung in der Kombination der Maschine mit verschiedenen Geräten.The invention also consists in combining the machine with different ones Devices.

Auf der beiliegenden Zeichnung ist ein Ausführungsbeispiel des Erfindungsgegenstandes veranschaulicht.On the accompanying drawing is an embodiment of the subject of the invention illustrated.

Fig.zeigt im Aufriss,von der Seite gesehen das Fahrzeug, Fig.2 zeigt Einzelheiten der Konstruktion.Fig. Shows the vehicle in elevation, seen from the side, Fig. 2 shows Construction details.

Die Mittel zur automatischen Verriegelung der gelenkten Hinter-Achse sind folgende:und ihre Wirkungsweise: Durch Bewegung eines Hebels IO,in Fahrtrichtung wird über den Seilzug 11 und das Schaltgestänge 14 im Fahrantrieb 15 der Schnellgang eingelegt.Gleichzeitig wird der Seilzug 9 entlastet und eine Feder 8 drückt auf eine Wippe 5 über ein Lager einen Bolzen 4 durch die Führung 3 in eine Arretierung 2.Synchron unterbricht der Endschalter 7 den Stromkreislauf des Magnetventils für die Allradlenkung.Das Fahrzeug wird dann nur mit der Vorderachse gelenkten Durch Bewegung des Hebels 10 auf den Fahrer zu wird über den Seilzug 11 und das Schaltgestänge 14 im Fahrantrieb 15 der Arbeitsgang eingelegt.Dabei wird der Seilzug 9 gezogen und die Wippe 5'die über ein Lager 6 auf eine Feder drückt zieht dabei den Bolzen 4 durch die Führung 3 aus seiner Riegelstellung(2) und gibt,den Stromkreis ffi über den Endschalter 7,das Magnet-Ventil für die Allradlenkung frei.Das Fahrzeug wird dann mit Vorder-und Hinter-Achse gelenkt-.The means for automatically locking the steered rear axle are as follows: and their mode of operation: By moving a lever IO, in the direction of travel the overdrive is via the cable 11 and the shift linkage 14 in the drive 15 At the same time the cable 9 is relieved and a spring 8 pushes open a rocker 5 over a bearing a bolt 4 through the guide 3 in a lock 2. Synchronously, the limit switch 7 interrupts the circuit of the solenoid valve for the all-wheel steering, the vehicle is then only steered with the front axle Movement of the lever 10 towards the driver is via the cable 11 and the shift linkage 14, the work gear is engaged in the travel drive 15, while the cable 9 is pulled and the rocker 5 'which presses on a spring via a bearing 6 pulls the bolt 4 through the guide 3 from its locking position (2) and gives the circuit ffi over the limit switch 7, the solenoid valve for the all-wheel steering free. The vehicle is then steered with front and rear axles.
