Abstract

A clamp group mounting of a leaf spring to a round axle including alignment features is disclosed, which includes a round axle, a leaf spring and a clamp group connecting the leaf spring to a laterally extending axle. A locator ring is welded to an upper arcuate surface of the axle and is received in a recess in a spring seat. The clamp group includes the spring seat, a top pad and a plurality of fasteners that connect the top pad, leaf spring, and spring seat to the axle. The leaf spring extends longitudinally and at least forward or rearward relative to the axle, and includes a bore that receives a locator element that extends at least upward or downward from the leaf spring.
