Title
(EN) INSERT PIN FOR LEAF SPRING SUSPENSION
(FR) BROCHE D'INSERTION POUR SUSPENSION DE RESSORT A LAME SIMPLE
Abstract
(EN)
A leaf spring suspension includes a plurality of leaf springs fixedly secured together by a bolt in the form of a stack. A first leaf spring of the plurality of leaf springs has ends configured to be coupled to a vehicle frame. A pin extends through each leaf spring except for the first leaf spring to prevent splaying between the leaf springs during transverse loading of the suspension.
(FR)
La présente invention concerne une suspension de ressort à lame simple qui comprend une pluralité de ressorts à lame simple fixés ensemble par un boulon, sous la forme d'une pile. Un premier ressort à lame simple parmi la pluralité possède des extrémités pouvant être couplées à la carcasse d'un véhicule. Une broche se prolonge par le biais de chaque ressort à lame simple, à l'exception du premier, pour éviter l'évasement entre les ressorts à lame simple pendant le chargement transversal de la suspension.
