Disclosed are skids steer loaders (100) and vibratory roller attachments (200) embodiments in which an improved variable isolator (270) is provided to isolate the skid steer loader, and thus the operator of the loader, from the severity of the vibrations in the vibratory roller. The vibratory roller attachment includes a frame (210) configured to be mounted to the skid steer loader. A drum (205) is supported by the frame, and an eccentric weight (250) is positioned within the drum. A plurality of variable isolators (270) couple the drum to the frame to provide isolation of the skid steer loader from vibrations of the vibratory roller. The plurality of variable isolators each have a non-cylindrical exterior shape (805). The non-cylindrical shape can include an exterior surface having curved end portions (905; 910) separated by a substantially linear middle portion (920) to allow for improved deflection of the variable isolators, and thus improved vibration isolation between the attachment and the skid steer loader.

Cette invention concerne des modes de réalisation de chargeuses à direction à glissement (100) et de dispositifs adaptables de rouleaux vibrants (200). Dans lesdits modes de réalisation, un isolateur variable amélioré (270) est fourni pour isoler la chargeuse à direction à glissement, et partant le conducteur de la chargeuse, des vibrations importantes provenant du rouleau vibrant. Le dispositif adaptable de rouleau vibrant comprend un support (210) conçu pour être monté sur la chargeuse à direction à glissement. Un tambour (205) est supporté par le cadre, et un poids excentrique (250) est disposé à lintérieur du tambour. Une pluralité disolateurs variables (270) relient le tambour au support pour isoler la chargeuse à direction à glissement des vibrations du rouleau vibrant. Les isolateurs variables ont chacun une forme externe non cylindrique (805). La forme non cylindrique peut comprendre une surface externe présentant des parties dextrémité incurvées (905, 910) séparées par une partie intermédiaire sensiblement linéaire (920) pour permettre une déviation améliorée des isolateurs variables et partant une isolation améliorée des vibrations entre le dispositif adaptable et la chargeuse à direction à glissement.
