Abstract

Transmission hydrostatique conçue pour réduire la propagation des bruits. Elle comporte un corps monté dans un bâti principal 11 à l'aide de dispositifs 80 et 81 d'isolation empêchant la propagation des bruits d'origine hydraulique du corps de la transmission vers le bâti. Chacun de ces dispositifs comprend une plaque centrale disposée entre deux plaques laterales auxquelles elle est reliée par des couches de matière élastique qui travaillent en cisaillement sous de faibles charges et en compression sous des charges plus élevées. Domaine d'application : transmissions hydrauliques.
