Definitions

  • the present invention relates to a bogie comprising at least two pairs of wheels and intended for off-road loaders.
  • Machines which are fitted with a plurality of wheels and intended for work in more or less difficult ter ⁇ rain, for instance forest clearing work, transporta- tion of timber etc., are known to the art. For reasons of economy, there is a tendency to produce these machines in progressively larger dimensions with the result that they become progressively more energy demanding in operation.
  • One result of this development is reflected in the increase in wear and tear on the machine carrying surface (forest ground) and the ma ⁇ chines themselves, and there is now a demand for technical improvements that will reduce these draw ⁇ backs for environmental and economical reasons.
  • the object of the present invention is to provide for machines and loaders that are intended particularly for off-road work bogies which are so constructed as to considerably reduce these drawbacks.
  • a bogie constructed in accordance with the invention comprises at least two pairs of wheels where each wheel pair is pivotal or tiltable on a shaft which extends at right angles to the wheel axles (horizontal on flat ground) and the two wheel pairs are together rotatable about a further shaft which extends at right angles to the first-mentioned shaft.
  • a bogie of this construc ⁇ tion can be used as a basic unit for the construction of more complex bogeys which together include 4, 8, 12, 16, 32 wheel pairs and so on, which are so con- structed and arranged that each unit will function independently with maximum adaptation to the underly ⁇ ing driving surface, which results in minimum puncti- form loading (the pressure is distributed evenly on the ground) and minimum energy consumption, i.e. the wear and tear on the driving surface is reduced, terrain accessibility is improved and the useful life of the machines is extended.

Abstract

Un boggie comprend deux paires de roues (11, 12). Chaque paire de roues est montée, de façon à effectuer un déplacement rotatif ou inclinable, sur un arbre (13) s'étendant à angle droit par rapport au sens de l'essieu (111, 121) des paires de roues respectives, selon un angle de rotation total de 30° environ. Les paires de roues sont montées rotatives sur un deuxième arbre (14) s'étendant à angle droit par rapport aux premiers arbres (13). Un boggie combiné comprend deux sous-boggies (400, 410), dont chacun comprend deux ensembles réciproquement identiques possédant chacun deux (21, 22; 21', 22') ou quatre (31, 32, 31', 32'; 33, 34, 33', 34') paires de roues. Un sous-boggie (400) est accouplé à un véhicule moteur (40) et un autre sous-boggie (410) est accouplé à un véhicule de chargement (41). Le véhicule moteur et le véhicule de chargement sont rotatifs l'un par rapport à l'autre autour d'un axe (y-y) s'étendant à angle droit par rapport au sens de l'essieu des paires de roues respectives et également autour d'un axe (x-x) s'étendant parallélement par rapport au sens de l'essieu des paires de roues respectives. L'angle (α) entre les sens longitudinaux (401, 411) des côtés supérieurs des sous-boggies respectifs est toujours » 180°.
