Ball joint seal with heat shield

For covering each of a first ball joint assembly between a first arm element of a vehicle steering knuckle and an end portion of a lower control arm, and a second ball joint assembly between a second arm element of said steering knuckle and an end portion of a tie rod, both ball joint assemblies being positioned adjacent a brake rotor, a pair of ball joint seal devices each comprising a rubber housing adapted to mount around a respective one of said first and second ball joint assemblies, and each said rubber housing having a heat shield formed integrally therewith, said heat shield comprising a steel insert integrally molded within one end of each said rubber housing, characterized by an arcuate-shaped steel flange external of said one end and formed on a portion of a peripheral edge of said steel insert adjacent said brake rotor and integrally molded in an extension of said rubber housing.

A Ball joint assembly located adjacent a source of heat and comprising a ball joint pivotally mounted in an opening formed in a surrounding first movable member, a stud extending from said ball joint and secured in an opening in a second movable member, and a seal device having a partial spherical rubber body having oppositely disposed open ends mounted around said stud and at least a portion of said ball joint intermediate said first and second movable members, an external flange formed on one of said open ends, said seal device having a heat shield disposed thereon adjacent said source of heat, said heat shield comprising a steel insert integrally molded in said external flange, and a concentric longitudinally extending steel flange formed on said steel insert external of said external flange and integrally molded on a peripheral edge of said external flange adjacent said source of heat.
