Abstract

The invention relates to a suspension system of a vehicle axle, comprising:—a leaf spring (11);—a rear attachment device which is configured to be secured to a vehicle frame (2) and which receives a rear end portion (14) of the leaf spring (11) so as to allow said leaf spring rear end portion to slide longitudinally relative to the rear attachment device; wherein:—the rear attachment device (24) comprises a fastener (26) extending substantially transversally and a pad (28) secured on the rear attachment device above the fastener;—the leaf spring rear end portion (14) is substantially flat and has an upper face (15) in contact with the pad (28) and a lower face (16);—and the suspension system further comprises a retaining member (30) which is a piece separate from the leaf spring (11). The retaining member (30) is secured to and under the leaf spring rear end portion (14) by a fixing element (50) located rearward of the pad (28), the retaining member (30) including a front wall (33) arranged forward of the fastener (26), and configured to abut against the fastener (26) in order to prevent a rearward movement of the leaf spring (11) relative to the rear attachment device (24) above a predetermined limit.
