摘要

A suspension assembly for a vehicle has at least two leaf spring assemblies providing at least two load paths. The leaf springs are vertically separated and mount to a shackle assembly which is mounted to the chassis. The shackle assembly has at least two shackles and may have a load transfer assembly. The leaf springs also attach to a spring hanger opposite the shackle assembly. The load transfer assembly has inner and outer load transfer plates to which the leaf springs and the shackles fasten to form a four-bar linkage.
