Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
253 words
In a vehicle having a single piece front axle journalling a steerable wheel assembly for horizontal turning movement about a generally vertical axis by a steering control arm connected with the wheel assembly including a pitman arm horizontally intersecting the turning axis and movable about the turning axis in unison with turning movement of the steerable wheel assembly and having a leaf spring assembly overlying the axle and secured thereto by a spring clamp bolt, the improvement comprising: pitman bracket means rigidly secured to said pitman arm and having an apertured end portion projecting forwardly of said turning axis, said pitman bracket means comprising an elongated plate longitudinally underlying said pitman arm, an apertured ear transversely secured to said plate intermediate its ends in upstanding relation for surrounding one end portion of said pitman arm, and, a clamp connecting the other end portion of said pitman arm to said plate; fixed bracket means including an apertured prong supported by said spring clamp bolt forwardly of said axle; spring assembly means including a shaft supported intermediate its ends by said apertured prong for longitudinal reciprocating movement relative thereto, said spring assembly means including a pair of compression springs respectively surrounding opposing end portions of said shaft on opposing sides of said apertured prong, and, spring retaining means on the respective end portion of said shaft for adjusting the compression of said springs; and, universal joint means connecting one end portion of said shaft with the apertured end portion of said pitman arm bracket means.
