Title
(EN) ANTI-SHIMMY CASTER WHEEL MOUNTING
(FR) DISPOSITIF DE FIXATION ANTI-VIBRATIONS POUR ROULETTES
Abstract
(EN)
An assemblage for mounting a caster wheel (3) on a depending stationary post (10) on a wheeled load carrier comprises a body element (20) having a cylindrical chamber (20a) concentrically surrounding the support post (10). The body element has a bracket (20b) for mounting a caster wheel for rotation about a horizontal axis. A vertical stack of washers (21, 22) surround the support post and alternate ones of such washers are secured to the support post and rotatable within the cylindrical chamber while the remainder of such washers are co-rotatable with the body element about the axis of the support post. The cylindrical chamber is filled with a lubricating fluid to a sufficient depth to cover all abutting surfaces of said washers, thereby providing viscous fluid sharing resistance to shimmying movement of the caster wheel relative to the support post.
(FR)
L'invention concerne un assemblage pour fixer une roulette (3) sur un montant fixe (10) d'un support de charges à roulettes. Cet assemblage comprend un corps (20) pourvu d'une chambre cylindrique (20a) enveloppant de manière concentrique le montant de support (10). Le corps comporte une patte (20b) pour fixer une roulette en vue de sa rotation autour d'un axe horizontal. Une pile verticale de rondelles (21, 22) entourent le montant de support. Ces rondelles sont fixées, en alternance, au montant de support et peuvent tourner dans la chambre cylindrique tandis que le reste des rondelles peut entrer en co-rotation avec le corps autour de l'axe du montant de support. La chambre cylindrique est remplie d'un fluide lubrifiant jusqu'à une profondeur suffisante pour recouvrir toutes les surfaces des rondelles placées en butée. On obtient ainsi une résistance au cisaillement opposée par le fluide visqueux aux vibrations de la roulette par rapport au montant de support.
