Definitions

  • the invention relates to a handling and earthmoving vehicle, taking loads cantilevered with respect to its front axle, by means of a tool-carrying lifting arm, according to the preamble of claim 1.
  • a handling and earthmoving vehicle taking loads cantilevered with respect to its front axle, by means of a tool-carrying lifting arm, according to the preamble of claim 1.
  • Handling vehicles corresponding to the preamble of the claim are already known.
  • This document US-A-4,082,197 relates to a handling vehicle, the chassis of which is composed of two elements, carrying respectively the front axle and the rear axle, elements articulated together around a vertical hinge axis.
  • This vehicle also comprises an upper carrying arm, integral with the rear element of the chassis by a horizontal axis allowing this arm disposed longitudinally and above the chassis, to raise or lower the load carried.
  • the vertical hinge joint linking the front and rear elements of the chassis, is taken advantage of, by lifting the carrying element of the lifting arm by means of stabilizing crutches, located on either side. elements of the chassis, between them, in order to allow the load-carrying arm to pick up or deposit it, in a limited sector, situated on either side of the longitudinal axis of the vehicle.
  • This known embodiment allows only a very limited lateral orientation of the support arm; limited by the small clearance allowed by the hinge joint located between the front and rear elements of the chassis, elements which, due to their own width, interfere with each other in this clearance and thus limit their importance.
  • the invention consists of a frame in two elements, carrying respectively the front wheels and the rear wheels, in which, as characterized in the claims, the front element is carrying a vertical pivot, and a stabilizing frame, constituting, when lowered to the ground, a vehicle riser whose wheels no longer rest on the ground; however, the rear element, constituted by a bridge beam, carrying at the front a rotation box receiving the pivot, can rotate freely, around, and above, the front element.
  • This rear element also carrying the lifting arm receiving the load, the latter itself can therefore be deposited, or taken, by the arm, in a sector of 360 ° around the stabilizer resting on the ground.
  • the vehicle is composed of a gearbox (1), on which are grafted the important elements of the entire device, and, in particular, the motor (2) which is coupled to it , the driving wheels (3). It also supports, by means of connecting rods (4a) articulated directly on the carrier rockets (1a) (figure 2) of the gearbox (1), and (4b), a stabilizer (4), the lowering is controlled by the cylinders (4c).
  • a pivot (5) receives the rear element of the chassis.
  • This rear element is composed of a simple girder-bridge (6), receiving: at the front, a rotation box (7), and, at the rear, a set of two gussets (8), ensuring, at at the same time, the rear axle support (9) of the vehicle, the articulation rear of the lifting arm (15) by its horizontal axis (10), and the articulation (11b) of the lifting cylinder (1 1
  • FIG. 4 An embodiment of the orientation and rotation control is given in FIG. 4, in which a hydraulic motor (12), integral with the housing (7), driving a toothed pinion (13), meshes with a toothed crown (14 ), integral with the pivot (5), therefore with the gearbox (1).

Claims (3)

1. Material- und Bodenbewegungsfahrzeug, das seine Ladung in bezug auf seine vordere Tragachse seitlich mittels eines Hebelarmes (15) aufnimmt und das aus einem Chassis besteht, das sich aus zwei Elementen zusammensetzt - einem vorderen (1) und einem hinteren Element (6), miteinander durch ein Drehgelenk mit vertikaler Achse (5) verbunden, wobei das vordere Element (1) mit einem Druckschraubenmotor (2) ausgestattet ist, der die Vorderräder (3) antreibt; das hintere Element (6), Träger der hinteren Achse (9), ist mit den Hinterrädern (3a) ausgestattet; eine horizontale Hinterachse (10) dient als Gelenk für den Hebelarm (15) und eine Wagenheber (11) als Verbindung zwischen dem Hebelarm (15) und dem genannten hinteren Element (6) steuert das Anheben bzw. Senken des Hebelarmes (15); ein Stabilisator (4), der mit genanntem vorderen Element (1) durch Stangen (4a und 4b) verbunden ist, wird durch den Druck der Wagenheber (4c) zu Boden gesenkt; charakteristisch dabei ist, dass das vordere Chassiselement (1) die Achse des vertikalen Drehgelenkes (5) trägt; dass der Stabilisator (4), wenn er zu Boden gesenkt wird, eine Hebevorrichtung für das Fahrzeug darstellt, indem er das Anheben der beiden Chassiselemente - hinteres Element (6) und vorderes Element (1) bewirkt und die Vorder- und Hinterräder nicht länger auf dem Boden bleiben und dass das hintere Element (6) des Chassis aus einem Hinterachsträger (6) besteht, der frei im Kreis und über das vordere Element drehen kann und der an der Vorderseite ein Rotationsgehäuse (7) mit der Achse des Drehgelenkes (5) trägt.
2. Charakterisch für das Fahrzeug gemäss Forderung 1 ist, dass der Hinterachsträger (6) auf der Rückseite mit zwei Einsatzstücken (8) ausgestattet ist, die den Aufbau, bestehend aus dem rückwärtigem Gelenk (10) des Hebelarmes (15), einem Gelenk des Wagenhebers (11) und der hinteren Tragachse (9) für die Hinterräder (3a) trägt; d.h. wenn das vordere Element (1) auf dem Grund auf seinem Stabilisator liegt (4), dann dreht sich der Hinterachsträger durch den Impuls des Steuergerätes, z.B. des Motors (12), der Teil des Gehäuses (7) bildet, um das Gelenk (5); das Gehäuse trägt das Getriebe (13), das in den Umkreis eines gezahnten Antriebskegelrades (14) eingreift, das mit dem vorderen Element (1) verbunden und konzentrisch zum Drehgelenk angebracht ist (5).
3. Charakteristisch für das Material- und Bodenbewegungsfahrzeug gemäss Forderungen 1 und 2 ist, dass die Fahrtrichtung des Fahrzeugs auf der Strasse sowie die Drehung des hinteren Chassisteiles (6), das die Ladung trägt, während das vordere Chassiselement (1) auf dem Boden auf dem Stabilisator aufliegt (4), durch ein und denselben Richtungsmechanismus betätigt werden.
