  • Patent number: 11090995
    Abstract: The invention relates to a suspension system of a vehicle axle, comprising: a leaf spring (11); a rear attachment device (24) configured to be secured to a vehicle frame (2) and comprising two parallel walls (40) spaced apart along a transverse direction by a distance (d). A rear end portion (14) of the leaf spring (11) is received in the rear attachment device (24), between said walls (40), and is capable of sliding longitudinally relative to the rear attachment device. The leaf spring rear end portion (14) has a first width (w1) which is smaller than the distance (d), and the leaf spring (11) has a second width (w2) which is greater than the distance (d), at least in a blocking portion (30) of the leaf spring (11) located forward of the rear end portion (14).
