Abstract: front page image
(EN)Land and earthworking vehicles are subject to extreme vibrational forces during operation, which are a source of discomfort to the vehicle"s operator, and also produce high levels of noise. By mounting portions of the vehicle, such as its cab, to the supporting frame by resilient supports, the notted problems can be overcome. The mounting structure includes a shock-absorbing apparatus (12) for mounting a platform (13) or the like on a frame (14). Each apparatus (12) includes a fastening member (26) extending from the platform (13) through an aperture (22) in the frame (14) and carries a support (30) on the opposite side of the frame (14) from the platform (13). A spacer (24) extends from the platform (13) to the support (30) with a resilient bushing (16) encircling the fastening member (26) between the platform (13) and the frame (14). A second resilient bushing (18) encircles the fastening member (26) between the frame (14) and the support (30). Each resilient bushing (16, 18) includes at least one ring (32, 36) of each bushing (16, 18) having a portion compressed between the washer (30) and the platform (13) with at least one second ring (34, 38) of each bushing (16, 18) being initially spaced from the platform (13) or from the support (30). The second rings (34, 38) of each bushing (16, 18) are of a material that is harder and less resilient than the material of the first rings (32, 36).
(FR)Les vehicules de terrassement sont soumis a des forces de vibration extremes pendant leur fonctionnement, qui sont une source d"inconfort pour le conducteur du vehicule et produisent egalement des niveaux de bruit tres eleves. En montant des parties du vehicule telle que sa cabine sur le chassis de support a l"aide de supports elastiques ces problemes peuvent etre surmontes. La structure de montage comprend un appareil amortisseur (12) pour le montage d"une plate-forme (13) ou autre sur un chassis (14). Chaque appareil (12) comprend un organe d"attache (26) s"etendant depuis la plate-forme (13) au travers d"une ouverture (22) dans le chassis (14) et porte un support (30) sur le cote oppose du chassis (14) par rapport a la plate-forme (13). Un dispositif d"espacement (24) s"etend depuis la plate-forme (13) jusqu"au support (30) avec un manchonnage elastique (16) encerclant l"organe d"attache (26) entre la plate-forme (13) et le chassis (14). Un second manchonnage elastique (18) encercle l"organe d"attache (26) entre le chassis (14) et le support (30). Chaque manchonnage elastique (16, 18) comprend au moins une bague (32, 36) de chaque manchonnage (16, 18) ayant une partie comprimee entre la rondelle (30) et la plate-forme (13), au moins une seconde bague (34, 38) de chaque manchonnage (16, 18) etant initialement espacee de la plate-forme (13) ou du support (30). Les secondes bagues (34, 38) de chaque manchonnage (16, 18) sont faites en un materiau qui est plus dur et moins elastique que le materiau des premieres bagues (32, 36).
