Definitions

  • the invention relates to a device for fastening a working device, for. B. the coulter of a snow plow, on a vehicle, with a pivotable on the vehicle about a horizontal, transverse to the longitudinal direction of the main axis of the base frame, which is pivotally connected to the implement at all ends by a ball or universal joint, with the usual adjustment attack the working position of the implement around the vertical and the horizontal, parallel and transverse to the vehicle longitudinal axes provided hydraulic cylinders directly on the implement.
  • a device of this type is known from DE-B-1 484 723, in which the working plate is attached by means of a ball and socket joint at a distance from the longitudinal plane of the vehicle to a, as usual, height-adjustable base frame about a horizontal axis arranged transversely to the vehicle and can be pivoted around the ball joint on all sides by means of hydraulic cylinders acting on the shield.
  • This design requires complicated construction of the guides and allows only small swivel angles around the vertical and around the longitudinal central axis.
  • the work plate is connected in the lower center by means of a ball joint directly and above via a link to the base frame which can be raised and lowered.
  • the work plate can be pivoted about the ideal axis, which passes through the ball joint and the joint between the work plate and handlebar, by means of hydraulic cylinders.
  • This ideal swivel axis is guided by the handlebar so that it can move on the surface of an imaginary cone, the tip of which lies in the ball joint and the axis goes through the joint between the handlebar and the main frame. In this respect, there is a forced operation, which means only little freedom of movement for the work plate.
  • AT-B-340 994 discloses a device in which the implement can be pivoted about one of the three mutually perpendicular spatial axes.
  • the device has four frames which are successively articulated to one another.
  • the joint axes run parallel to one of the spatial axes.
  • the enormous weight of the facility has a particularly negative effect on the center of gravity of the vehicle.
  • the joint on the base frame is arranged centrally in the device of the type mentioned at the beginning and at the front end of the base frame there is a link which can be pivoted about an axis parallel to the main axis and which is approximately perpendicular to the base frame and upwards is directed and connected to the implement by means of a handlebar running approximately parallel to the longitudinal direction of the vehicle, a hydraulic cylinder arranged parallel to the main axis acting on the one hand at the upper end of the handlebar and on the other hand on a console of the implement.
  • the object of the invention is shown schematically in an exemplary embodiment in longitudinal section and in plan view.
  • a base frame 1 is articulated in height about a main axis 2 on the vehicle, not shown. He carries at the front end a tab 3, which is engaged by a hydraulic cylinder 4, indicated by a dash-dotted line, which is articulated at 5 on the vehicle. At the front end of the frame 1 arms 6 are provided which carry a ball joint 7, by means of which the implement 8, in the drawing a ploughshare, is articulated on the base frame 1. Furthermore, a wishbone 9 is pivotally mounted at the front end of the base frame about an axis 2a parallel to the main axis. The wishbone 9 projects upwards and is provided with a pin 10. An essentially parallel pin 11 is provided on the coulter 8 and the two pins 10 and 11 are connected by means of a link 12 as a coupling member, so that in connection with the ball joint there is a kind of parallelogram between the link 9 and the implement 8.
  • a pin 14 is provided on a console 13 of the working device 8, which pin is parallel to the pin 10 of the handlebar 9 and is covered by the pin 10 in FIG.
  • the implement 8 has a tower 17 which is connected at its free end by means of a universal joint 18, 19 to a hydraulic working cylinder 20 indicated by a dash-dotted line in FIG. 1, which acts articulated at 21 on the vehicle.
  • this working cylinder 20 By means of this working cylinder 20, the working device can be tilted about the axis designated 22 in FIG. 2.
  • Fig. 2 Dotted lines indicated hydraulic cylinders 23, 24 are provided, which act on the one hand at 25, 26 on the base frame 1 and by means of the cardan joints 27, 28 on the implement. This makes it possible to pivot it about the axis designated 29 in FIG. 1.
  • the invention is not restricted to the exemplary embodiment shown. Both the shape of the base frame 1 and the handlebar 9 can vary. It is essential that the implement is gimbally connected directly to the base frame and that the hydraulic cylinders effecting the adjustment of the implement about the three spatial axes act directly on the implement.

Abstract

Le dispositif, destiné p. ex. à fixer une lame d'un chasse-neige à un véhicule présente un cadre de base (1) oscillant horizontalement autour d'un axe principal (2) tranversal au sens longitudinal du véhicule. L'outillage de travail (8) est fixé par un joint à rotule (7), joint universel ou similaire au milieu et sur le devant de ce cadre de base. Pour positionner l'outillage (8) sur la verticale et l'horizontale le dispositif présente des cylindres hydrauliques (23, 24, 15, 20) agissant directement sur l'outillage même et qui sont disposés parallèlement et transversalement à des essieux articulés (29, 16, 22) disposés dans l'axe longitudinal du véhicule. Le cadre de base (1) est déplaçable en hauteur le long de l'axe principal (2) au moyen d'un cylindre hydraulique (4) et sur le devant de ce cadre (1) est disposé un bras oscillant (9) autour d'un axe (2a) parallèle à cet axe principal (2), bras qui est dressé vers le haut et disposé à peu près perpendiculairement au cadre de base. Ce bras oscillant est connecté à l'outillage de travail (8) par un autre bras oscillant (12) à peu près parallèle au sens longitudinal du véhicule, tandis que le cylindre hydraulique (15) à peu près parallèle au sens longitudinal de l'outillage (8) agit d'une part sur l'extrémité supérieure du premier bras oscillant (9) et d'autre part sur une console (13) de l'outillage (8) dans le but de positionner l'outillage même autour d'un axe (16) parallèle au sens longitudinal du véhicule.

Claims (1)

  1. Dispositif pour le montage d'un instrument travaillant (8) par exemple, de la lame d'un chasse-neige, sur un véhicule, comprenant un cadre de base (1) qui peut pivoter sur le véhicule autour d'un axe principal horizontal (2) orienté transversalement à la direction longitudinale du véhicule et qui est relié à l'instrument travaillant (8) à son extrémité avant, au moyen d'un joint articulé à rotule ou de cardan (7) admettant la rotation dans tous les sens, et dans lequel les vérins hydrauliques habituels (20, 23, 24, 15) utilisés pour régler la position de travail de l'instrument travaillant (8), en le faisant tourner autour de l'axe vertical et de l'axe horizontal qui s'étendent parallèlement et transversalement à la direction longitudinale du véhicule, attaquent directement l'instrument travaillant (8), caractérisé en ce que le joint articulé (7) est monté au milieu du cadre de base (1), et en ce que, à l'extrémité avant du cadre de base (1), est monté un bras oscillant (9) qui peut pivoter autour d'un axe (2a) s'étendant parallèlement à l'axe principal (2), bras oscillant qui est dirigé vers le haut, à peu près perpendiculairement au cadre de base, et qui est relié à l'instrument travaillant (8) au moyen d'un bras oscillant (12) qui s'étend à peu près parallèlement à la direction longitudinale du véhicule, cependant qu'un vérin hydraulique (15) disposé parallèlement à l'axe principal (2) attaque, d'une part, l'extrémité supérieure du bras oscillant (12) et, d'autre part, une console (13) de l'instrument travaillant (8).
