Suivant une autre caractéristique le châssis supérieur comporte des longerons munis de rails passant sur des galets portés par le berceau et ce châssis est muni d'une embase munie du mât ou plus généralement de l'équipement de l'engin ainsi que la cabine du poste de conduite.According to another advantageous characteristic R3 this assembly by two crowns resting on each other and one of which has fixed drive means (teeth) and the other is equipped with a actuator such as a motor for rotating the movable crown by compared to the fixed crown with a grainy pinion in the teeth of the fixed crown, offers the advantage of excellent stability compared to a central pivot and allows the various accessories to be housed in the crown and passages of hydraulic lines, coming from the upper chassis fitted the motor and the pump and the means for controlling hydraulic circuits, to join the different parts of the machine and in particular the means for driving the lower chassis or the pivoting means and rotation. According to another characteristic, the cradle is formed of a chassis carrying bearings to receive an axis also housed in the bearings of the mobile crown as well as the rollers forming the travel path of the upper chassis. Next another characteristic the upper chassis has side members fitted with rails passing over rollers carried by the cradle and this chassis is provided of a base fitted with the mast or more generally of the equipment of the machine and the driver's cabin.

Le moyen d'entraínement pour pivoter le berceau recevant le châssis supérieur, par rapport à la couronne mobile est formé par au moins un vérin et de préférence deux vérins montés entre la couronne mobile et le berceau. Dans le cas de deux vérins, ceux-ci sont de préférence disposés dans les positions symétriques par rapport à l'axe de basculement du berceau sur la couronne mobile.The drive means to pivot the receiving cradle the upper frame, relative to the movable crown, is formed by at minus one cylinder and preferably two cylinders mounted between the crown mobile and the cradle.

La structure de l'équipement de la chenille 12 de l'autre côté du châssis inférieur est identique.The structure of the equipment of track 12 on the other side of the lower chassis is identical.

Le châssis inférieur 1 est, par exemple, constitué par un caisson ou par des poutres transversales avant et arrières 12, 13 portant le châssis tournant par l'intermédiaire d'une plaque 14. Le châssis tournant 2 est formé de deux couronnes, une couronne inférieure 21 et une couronne supérieure 22, la couronne inférieure étant fixe par rapport au châssis inférieur 1 et la couronne mobile 22 tournant par rapport à la couronne inférieure. La couronne mobile 22 s'appuie sur la couronne fixe 21 par des organes de roulement décrits ultérieurement. L'entraínement en rotation de la couronne mobile 22 est assuré par un moyen d'entraínement qui sera également décrit ultérieurement.The lower chassis 1 is, for example, constituted by a box or by front and rear transverse beams 12, 13 bearing the rotating chassis via a plate 14. The rotating chassis 2 is formed by two crowns, a lower crown 21 and a upper ring 22, the lower ring being fixed relative to the lower chassis 1 and the movable crown 22 rotating relative to the lower crown. The movable crown 22 rests on the crown fixed 21 by rolling bodies described later. The rotating crown 22 is driven by a drive means which will also be described later.

Le châssis tournant 2 porte un berceau oscillant 3 relié au châssis tournant par un palier avant 31-1 et un palier arrière 31-2 ainsi que par des vérins de basculement 32-1, 32-2 commandant le mouvement du berceau oscillant 3 autour de l'axe défini par les deux paliers 31-1, 31-2. Selon la vue de la figure 1, l'axe géométrique défini par les deux paliers 31, 32 est dirigé dans le sens longitudinal du berceau oscillant 3.The rotating chassis 2 carries an oscillating cradle 3 connected to the chassis rotating by a front bearing 31-1 and a rear bearing 31-2 as well only by tilt cylinders 32-1, 32-2 controlling the movement of the oscillating cradle 3 around the axis defined by the two bearings 31-1, 31-2. According to the view in Figure 1, the geometric axis defined by the two bearings 31, 32 is directed in the longitudinal direction of the oscillating cradle 3.

Le châssis supérieur 4 est porté par le châssis oscillant 3 par l'intermédiaire d'organes de translation tels que des galets et des rails permettant au châssis supérieur 4 de se déplacer par rapport à l'axe de pivotement du châssis tournant 2 pour les manoeuvres de l'engin et en particulier pour l'équilibrage par le déplacement du centre de gravité en fonction de la charge portée par l'engin. Dans cette réalisation, les appuis de glissement ou de roulement (les patins ou les galets) sont portés par le châssis pivotant et les rails par le châssis supérieur, de manière à réduire l'encombrement sans réduire la course de manoeuvre entre ces deux ensembles.The upper chassis 4 is carried by the oscillating chassis 3 by means of translation devices such as rollers and rails allowing the upper chassis 4 to move relative to the axis of pivoting of the rotating frame 2 for maneuvering the machine and particularly for balancing by moving the center of gravity in depending on the load carried by the machine. In this realization, the supports sliding or rolling (the pads or rollers) are carried by the swivel frame and the rails through the upper frame, so as to reduce space without reducing the maneuvering stroke between these two assemblies.

De façon plus détaillée, le châssis tournant 2 est représenté à la figure 2 qui montre la couronne fixe 21 ou couronne d'orientation portant la couronne rotative 22 munie de deux paliers 23-1, 23-2 alignés pour recevoir l'axe des paliers 31-1, 31-2 du berceau oscillant 3 pour former l'axe radial autour duquel bascule le berceau pour corriger l'assiette du châssis supérieur. Ces paliers sont fixés au fond 24 de la couronne 22 et à la couronne même.In more detail, the rotating frame 2 is shown in Figure 2 which shows the fixed crown 21 or orientation crown bearing the rotary crown 22 provided with two bearings 23-1, 23-2 aligned to receive the axis of the bearings 31-1, 31-2 of the oscillating cradle 3 to form the radial axis around which the cradle rocks to correct the attitude of the upper chassis. These bearings are fixed to the bottom 24 of the crown 22 and at the crown itself.

La couronne rotative 22 comporte également deux double chapes 25-1, 25-2 pour recevoir chacune le pied d'un vérin de basculement 32-1, 32-2 du berceau oscillant 3.The rotary crown 22 also includes two double brackets 25-1, 25-2 to each receive the foot of a tilt cylinder 32-1, 32-2 of the swinging cradle 3.

Les moyens de support et de roulement de la couronne rotative 22 par rapport à la couronne fixe 21 sont constitués par des paliers à roulement répartis régulièrement à la périphérie entre les couronnes 21, 22. L'entraínement en rotation est assuré par exemple par un actionneur sous forme de moteur hydraulique, fixé au fond 24 et traversant l'orifice 24-1 ou 24-2 du fond 24 pour engrainer avec son pignon dans une couronne dentée 25 portée par la couronne fixe 21. L'actionneur non représenté est de préférence un moteur hydraulique.The means of support and rolling of the rotary crown 22 with respect to the fixed crown 21 are constituted by bearings bearing regularly distributed on the periphery between the rings 21, 22. The rotary drive is provided for example by an actuator in the form of a hydraulic motor, fixed to the bottom 24 and passing through the hole 24-1 or 24-2 of the bottom 24 to drive with its pinion in a toothed crown 25 carried by the fixed crown 21. The actuator not shown is preferably a hydraulic motor.

La figure 2 montre également la forme incurvée du bord supérieur 22-1, 22-2 de la couronne mobile 22.
