Abstract:
A tillage machine has an undercarriage that utilizes a triple axle walking beam wheel assembly for each load-supporting wheel assembly of the center section of the machine. Hydraulically powered lift arms are connected with the wheel assemblies to raise and lower the chassis of the machine as the wheel arms are swung downwardly and upwardly relative to the chassis. Each wheel assembly includes a primary walking beam pivoted to the lower end of the wheel arm, and a secondary walking beam pivoted to the rear end of the primary beam. A single front wheel is disposed at the front end of the primary beam, while a pair of wheels are disposed on the secondary beam on opposite fore-and-aft sides of the pivot connection with the primary beam. An abutment on the wheel arm engages a stop on the primary beam upon downward rotation of the wheel arm by a predetermined amount relative to the chassis such that continued downward movement of the wheel arm causes load to shift partially off the front wheel and onto the rear wheels.
Abstract:
A vehicle suspension comprising a pair of plate members (13 and 14) supported from each other in spaced substantially parallel relationship, the support between said plate members being provided by each plate member having a shaft (15 and 16) extending perpendicularly therefrom and wherein at least a portion of said shafts are concentrically interengaged for relative rotation therebetween about their central axis, such shafts (15 and 16) being supported one from the other by a bearing member (18), said plate members (13 and 14) being further supported from each other by a block (26) of resilient solid material bonded to the opposed faces (17 and 27) of the plate members (13 and 14) in the region surrounding the shaft.
Abstract:
La présente invention concerne un module de liaison au sol destiné à supporter au moins une partie d'un châssis de véhicule, comprenant une chape (5) rendue solidaire du châssis et au moins une roue (1) permettant le déplacement dudit véhicule, au moins une roue du module étant rendue mobile par des moyens de motorisation (2), la position de l'axe de chaque roue du module étant déplaçable par rapport au sol et au châssis au moins par des moyens de braquage (31), chaque roue (1) du module étant rendue solidaire d'un balancier de suspension (4) lui-même rendu solidaire d'une part de la chape (5), et d'autre part de moyens de suspension (40) solidaire du châssis ou de la chape (5), de sorte que chaque roue (1) est déplaçable dans une direction verticale, sensiblement perpendiculaire au plan du châssis, indépendamment de la position et/ou du déplacement des autres roues du véhicule faisant partie ou non dudit module; chaque roue (1) du module étant destinée à être inclinable de sorte que l'angle formé entre l'axe (x) d'une roue et un plan parallèle au plan du châssis, dit angle d'inclinaison, est différent de 0[π]; le module de liaison au sol étant rendu solidaire de moyens de mesure et de commande contrôlant au moins les moyens de motorisation (2), les moyens de braquage (31), les moyens de suspension (40) et des moyens d'inclinaison des roues du module.
Abstract:
Adjustable wheel suspension for a utility vehicle with two wheels located on the same side of the vehicle (1 ), suspended on a vehicle frame (3). The wheels are mounted on separate supporting arms (14, 15) in such a way that they can rotate on separate wheel axles (18, 19) and can assume different height positions in relation to each other. The wheel suspension has a suspension part (13) arranged on the frame (3) on each side, mounted on a pivot axle (12) in such a way that it can pivot. This is mounted on the supporting arms (14, 15), in such a way that it can pivot, at a distance from the bearing axle (18, 19) of the respective wheel. Linear force devices (30, 31 ) are arranged between the frame and the movable suspension part, for controlling the position of the suspension part. Linear force devices (52, 53) are arranged between the supporting arms and the suspension part for controlling the rotational position of each supporting arm in relation to the suspension part and hence the height of each wheel axle in relation to the frame.
Abstract:
An air spring for use in an axle/suspension system of a heavy-duty vehicle includes a bellows and a piston. The bellows includes a bellows chamber. The piston includes a top portion, a bottom portion and a support stud. The support stud includes a first end and a second end, the first end of the support stud is secured to the top portion or the bottom portion of the piston, the support stud extending between the top portion and the bottom portion of the piston..
Abstract:
Le véhicule comprend au moins quatre roues et une base, lesdites roues étant rattachées par paire à la base par liaisons et formant un bogie par paire de roues, lesdits bogies étant articulés en rotation sur la base de manière à ce que le point de pivot de la trajectoire des roues ne soit pas physiquement existant et que ce point de pivot soit situé sous l'axe de rotation de roues lorsque la bogie est horizontale; la rotation d'un bogie étant transmise par un moyen de transmission à l'autre bogie de telle façon l'inclinaison de chacun des bogies par rapport à la base forme un angle de valeur identique mais opposée.
Abstract:
The invention relates to an arrangement for wheel suspension in a vehicle (1), comprising a vehicle frame (9) which bears at least two bogie axles (16, 17) which in turn each bear a wheel axle (5, 6), and also a first bogie element (18) and a second bogie element (19) which extend essentially in the longitudinal direction of the vehicle and are suspended in said vehicle frame (9). The invention is characterized in that it comprises at least one connection element (25; 41) extending essentially transversely to the longitudinal direction of the vehicle (1), which connection element (25; 41) is connected movably to at least one of said bogie axles (16; 17) and also to said bogie elements (18, 19), for transmission of a force which arises when relative movement takes place between the bogie axle (16; 17) concerned and said bogie elements (18, 19). By virtue of the invention, good comfort and a high degree of roll rigidity of the vehicle are obtained.
