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:
A tillage machine (10) has an undercarriage that utilizes a triple axle walking beam wheel assembly for each load-supporting wheel assembly of the center section (12) of the machine. Hydraulically powered lift arms are connected with the wheel assemblies (32,34) to raise and lower the chassis of the machine as the wheel arms (48) are swung downwardly and upwardly relative to the chassis. Each wheel assembly includes a primary walking beam (54) pivoted to the lower end of the wheel arm, and a secondary walking beam (56) pivoted to the rear end of the primary beam. A single front wheel (64) is disposed at the front end of the primary beam, while a pair of wheels (76) 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 full loadshare coilspring bogie suspension comprised of two loadshare beams (3) sitting above four coilsprings (2) atop two axle assemblies (1) of either live axle or independent axle configuration the axles (1) being located to the chassis (6) by 'A' Arms and control rods and suspended by the loadshare beams (3) and coilsprings (2). This loadshare coilspring bogie suspension has improved the level of performance for suspensions of this type as it offers several advances by giving increases in all of the parameters of ride quality, wheel articulation, chassis platform stability and reduced chassis torque input, all resulting from the interaction of the loadshare beams (3) with the coilsprings (2).
Abstract:
A tandem wheel assembly for mounting to a trailer, comprising a support for mounting to structure of the trailer, the support carrying a pair of tandem wheels via swing arm assemblies which permit each wheel to pivot relative to the support in a vertical plane, a suspension arm associated with the pair of tandem wheels, the suspension arm being pivotally attached to the support for pivotal movement in the vertical plane extending transversely to the axes of the wheels, opposite end portions of the arm being linked to a respective one of the swing arm assemblies of pair of wheels, the linkage of at least one of the end portions to its associated swing arm assembly including at least one suspension element.
Abstract:
An arrangement and method for enabling rotation movement between a tandem or caterpillar axle and a body of a vehicle. This type of vehicle comprises at least one body part (1, 5) that is provided with a tandem or caterpillar axle (3, 7). At least one body part (1, 5) comprises a main body (9, 9b) and an auxiliary body (11, 11 b) connected to it to rotate around the longitudinal axis (10) of the vehicle or an essentially parallel axis thereto. The tandem or caterpillar axle is connected substantially rigidly to said main body, and the body part (1, 5) has at least one actuator (12, 12b) for controlling the rotation movement between the main body (9, 9b) and auxiliary body. This way, changes in the position and motion status of the auxiliary body especially in relation to the rotation around the longitudinal axis (10) of the vehicle are arranged to cause in the actuator (12, 12b) a pushing or pulling motion that steers the auxiliary body (11, 11b) to a rotation movement for the purpose of arranging the auxiliary body to a substantially horizontal position.

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:
A presente patente de Modelo de Utilidade diz respeito a Disposição Técnica Introduzida em Balança Especial para Truck, a qual refere-se a um implemento rodoviário, sendo caracterizado por ser constituído por uma balança para truck, articulações nas extremidade e braços cuja função é interligar as extremidades da estrutura. Esta Balança Especial para truck oferece inúmeras possibilidades quanto à sua utilização em veículos tracionados, com trações 6x4, 6x2, 4x8, 2x8 e em caminhões com a quinta roda 6x2 ou 6x4, oferecendo a possibilidade de utilização de feixes de molas mais longas, e além disso, melhora a distribuição da carga nas rodas e eixos, de forma que garanta uma melhora significativa na força de tração e também evita os problemas com sobrecarga no veículo. Além disso destes benefícios, esta Balança Especial para Truck garante um melhor tracionamento quando em marcha ré, e fica mais leve com melhoria na Tara quando em substituição por eixos em Tandem.
