Lorsque la plaque annulaire (3) a ete tournee suffisamment dans le sens peripherique des roues de maniere a ce que les dispositifs de serrage (6) soient opposes aux cames de verrouillage (5), les dispositifs de serrage (6) sont serres en s'engageant avec les cames de verrouillage (5).
Abstract:
A suspended undercarriage assembly connectable to a multi-member frame assembly of a track system includes a beam having a leading portion and a trailing portion, at least one support wheel assembly connectable to the beam, at least one of a leading resilient bushing assembly and a trailing resilient bushing assembly including a bushing having an opening defined therein and being shaped and dimensioned for promoting deformation of the bushing in at least one of a vertical direction and a lateral direction. The bushing is resiliently deformable to permit movement of the beam relative to the multi-member frame assembly in the vertical direction and in the lateral direction, and to resiliently bias the beam towards a rest position with respect to the multi-member frame assembly. A track system having the suspended undercarriage assembly is also provided.
Abstract:
L'invention concerne une roue de secours (2) pour véhicule, en particulier pour véhicule automobile, destinée à être stockée dans un véhicule avant son emploi comme roue de secours, comportant une jante (21), dite jante principale, qui comporte une bande de roulement (23), ladite roue de secours (2) présentant une première position dite de stockage permettant d'en réduire son encombrement lors de son stockage et une seconde position dite d'utilisation permettant de l'utiliser comme roue de secours, caractérisée en ce que la roue de secours (2) comporte une jante complémentaire (23) qui présente un volume intérieur creux ouvert, la jante principale (21) et la jante complémentaire (23) présentant une forme adaptée pour que la jante principale (21) soit partiellement positionnée dans ledit volume intérieur creux lorsque la roue de secours (2) est dans sa position de stockage.
Abstract:
A dual wheel assembly is formed by an inner wheel (10) and an outer wheel (30) coaxially mounted on a common hub (11). The inner wheel (10) has an inner tyre (13) mounted on an inner wheel rim (12). The outer wheel (30) has an outer tyre (13A) mounted on an outer wheel rim (32). The tyres (13, 13A) are of the same size, but the diameter of the outer wheel rim (32) is smaller then the inner wheel rim (12), to permit the inner tyre (13) to pass over the outer wheel rim (32), thereby enabling the inner tyre (13) to be removed without first removing the outer wheel rim (32). Removable bead seats (37, 40) are provided between the oute wheel rim (32) and its tyre (13A). These bead seats (37, 40) are thicker than the corresponding bead seat(s) on the inner wheel (10) to compensate for the reduced diameter of the outer wheel rim (32).

Abstract:
A high offset dual vehicle wheel assembly includes a pair of full face wheels (20, 20) each defining an axis and including a wheel rim and a full face wheel disc. The rim includes an inboard tire bead seat retaining flange, an inboard tire bead seat, a generally axially extending well, and an outboard tire bead seat surface. The disc (42) includes a centrally located wheel mounting flange and an outer annular portion which defines an outboard tire bead seat retaining flange of the vehicle wheel and is located wholly outside a plane defined by the inboard tire bead seat retaining flange. The inboard tire bead seat (38) is provided with a radially in-turned flange having a generally radially inwardly sloping surface, a generally radially extending surface, and an axially extending surface. When the in-turned flange of the rim is positioned against an adjacent inner surface of the disc, a recess is formed between the inwardly sloping surface of the in-turned flange and the inner surface of disc, and a welding area is formed between the axially extending surface of the in-turned flange and the inner surface of disc. The recess (58) defines a groove for receiving a first weld (60), and the welding area defines an area for receiving a second weld (62). The welds cooperate to join the rim (30) and disc together and produce the full face vehicle wheel.
Abstract:
A road wheel for a tracked vehicle includes a first rim half (4) and a second rim half (6) operatively connected to the first rim half. The first rim half (4) includes at least a first portion (7a) that is angled away from the second rim half. The second rim half (6) includes at least a first portion (7b) that is angled away from the first rim half. A hollow cavity (20) is formed between the first portion of the first rim half and the first portion of the second rim half.
Abstract:
The present invention provides a novel design for quick tyre change in rear dual wheel assembly in a heavy transport vehicle. The invention provides a safe design that comprises a two-piece Z-section segmented lock ring retained in position inside a groove provided with female taper on the wheel rim. A portion of Z-section lock ring is tapered to 45 degrees on its exterior surface and abuts against a self locking taper on the bead seat band. The Z-section lock rings are retained inside the groove due to wedge action of self-locking taper cannot move from its position until an external force is applied on the ring towards the direction of the tyre position. A lip of the wheel rim acts as a hood over the Z-section segmented lock rings and prevents any loose parts flying off the rim during the tyre burst. Further in this safe design both inboard and outboard rim tyre support components are identical as both rims are of same diameter.
