Patent

CA 2300065

A suspension system (10) for supporting a frame member (20) on one side of a vehicle chassis on the adjacent end of an axle (26) comprises first and second frame brackets (18, 36), a single-leaf leaf spring (14), a leaf spring attachment member (46) and a wear plate (41). The first and second frame brackets (18, 36) are mounted to the frame member (20) on the outer sides thereof. The front end of the single-leaf leaf spring (14) is pivotally connected to the frame member (20) at the first frame bracket (18) and the rear end thereof is connected to the frame member (20) at the second frame bracket (36). The leaf spring attachment member (46) mounts to the rear end of the leaf spring (14) and connects the leaf spring (14) with the second frame bracket (36). The leaf spring attachment member (46) includes an arcuate upper surface (62) and a bottom surface. A rebound bolt (52) connects the rear end of the leaf spring (14) and the leaf spring attachment member (46) with the second frame bracket (36) and restricts the movement of the leaf spring (14) to a controlled range. The wear plate (41) is connected to the second frame bracket (36) and is associated with the leaf spring attachment member (46).

L'invention concerne un système (10) de suspension servant à soutenir un élément (20) de châssis sur un côté d'un châssis de véhicule, à l'extrémité adjacente d'un essieu (26). Le système de suspension comporte un premier et un second supports (18, 36) de châssis, un ressort à lame (14) comportant une seule lame, un élément (46) de fixation de ressort à lame et une plaque d'usure (41). Les deux supports (18, 36) de châssis sont montés sur l'élément (20) de châssis sur les côtés extérieurs de celui-ci. L'extrémité antérieure du ressort à lame (14) comportant une seule lame est connectée à l'élément (20) de châssis au premier support (18) de châssis, et l'extrémité postérieure du ressort est connectée à l'élément (20) de châssis au second support (36) de châssis. L'élément (46) de fixation de ressort à lame est monté sur l'extrémité postérieure du ressort à lame (14), et permet de connecter le ressort à lame (14) avec le second support (36) de châssis. L'élément (46) de fixation de ressort à lame présente une surface supérieure (62) arquée et une surface inférieure. Un boulon (52) de rebond permet de connecter l'extrémité postérieure du ressort à lame (14) et l'élément (46) de fixation du ressort à lame avec le second support (36) de châssis; et de limiter le mouvement du ressort à lame (14) à une plage réglée. Une plaque d'usure (41) est connectée au second support (36) de châssis, et est associée à l'élément (46) de fixation de ressort à lame.
