Abstract
Abstract An interlocking knuckle assembly consisting of an integral spindle and lower knuckle boss and an integral casting, including an upper knuckle boss and a spindle receiving opening in which the spindle of the forging is received. The casting is provided with a V-shaped groove formed therein opening toward the spindle receiving opening, and an upwardly projecting rib on the forging engages the groove on the casting when the spindle is fixed within the spindle receiving opening to prevent rotational movement of the spindle within the casting.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
217 words
In a knuckle assembly including an integrally formed casting, a first knuckle boss formed integrally with and projecting from said casting, means defining a spindle receiving opening formed through said casting in spaced relationship to said first knuckle, an integral forging consisting of a spindle shaft and a second knuckle boss formed integrally with said spindle shaft, and wherein said spindle shaft is received in said spindle receiving opening and fixed therein with the wall of said opening engaging a section of said spindle shaft and said second kNuckle boss is positioned in opposition to said first knuckle boss, improved means for preventing rotational movement of said spindle shaft within said opening and misalignment of said first and second knuckle bosses with respect to each other comprising: a. first interlocking means formed integrally with said casting outwardly of said spindle receiving opening therein, b. second interlocking means complementary to said first interlocking means and formed integrally with said forging, c. said second interlocking means being formed on a surface of said forging other than said section thereof engaged by said wall of said opening, and d. said first and second interlocking means being in engagement with each other outwardly of said spindle receiving opening with said first and second knuckle bosses positioned in opposition to each other.
Claim 2
Dependent Claim
