  • Device for mounting a composite material leaf spring
    Patent number: 5020824
    Abstract: A suspension for a vehicle having tandem axles includes a composite leaf spring connected between the axles. The leaf spring is constrained to bend about a transverse axis by a fixed elastic support having a concave, arcuate bottom surface whose center coincides with the transverse axis. The elastic support engages the top surface of the leaf spring at two points on opposite sides of the transverse axis, and is opposed by a central elastic element. The ends of the leaf spring are connected to the tandem axles by ball joints having elastic pads.
