Abstract
The invention relates to a suspension system of a vehicle axle, comprising:—a leaf spring ();—a rear attachment device which is configured to be secured to a vehicle frame () and which receives a rear end portion () of the leaf spring () so as to allow said leaf spring rear end portion to slide longitudinally relative to the rear attachment device; wherein:—the rear attachment device () comprises a fastener () extending substantially transversally and a pad () secured on the rear attachment device above the fastener;—the leaf spring rear end portion () is substantially flat and has an upper face () in contact with the pad () and a lower face ();—and the suspension system further comprises a retaining member () which is a piece separate from the leaf spring (). The retaining member () is secured to and under the leaf spring rear end portion () by a fixing element () located rearward of the pad (), the retaining member () including a front wall () arranged forward of the fastener (), and configured to abut against the fastener () in order to prevent a rearward movement of the leaf spring () relative to the rear attachment device () above a predetermined limit.
