  • Load leveling attachment for leaf spring suspension and method therefor
    Patent number: 5172930
    Abstract: The present invention provides an attachment for a vehicular leaf spring suspension system which redistributes the load on the vehicle to provide a level vehicle. The present invention, in one embodiment provides shoe members mounted on body members attached to the vehicle frame adjacent the leaf spring suspension systems. The shoe members are mounted on the body members on an eccentric axis to be pivotable relative to the body members.The shoe members are held in a non-engaging position when the vehicle is not to undergo overloading. When heavy loading is to occur, the shoe members are pivoted to an engaging position near the upper surface of the leaf springs. Abutment portions on the shoe members contact the leaf springs in a position normal to the planar surface of the leaf springs at the point of engagement.
