Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
148 words
A steering knuckle having an integral steering arm comprising a unitary sheet metal, generally cup-shaped member having a bottom wall with a flat portion adapted for mounting a wheel spindle thereon, a stepped portion having a flat shelf spaced from and substantially parallel to said flat portion adapted for mounting a disc brake caliper thereon, and a side wall having a pair of coaxial holes for connecting said steering knuckle to a pair of control arms for pivotal movement about a steer axis, said side wall further having substantially flat, parallel, closely spaced end portions connected by a bight continuous with said bottom wall forming a steering arm for pivoting the steering knuckle about the steer axis, and said side wall being continuous and having a continuous outturned flange between said end portions and connected to said bottom wall along substantially the entire periphery of the bottom wall.
