Abstract:
The vehicle rack and pinion steering system has an elongated rack bar. Tie rod connectors are provided on the ends of the bar. A rack gear teeth section is provided on the rack bar in a position parallel to and spaced from the rack axis. A cylindrical bearing surface is on the opposite side of the rack axis from the rack gear teeth section. The bearing surface has a fixed radius and is concentric with the rack axis. The rack section width is at least twice the fixed radius. Secondary bearing contact surfaces join the bearing surface, extend toward the rack gear teeth section and diverge from each other. Contact between the bearing and surface shifts the point of convergence of forces on the rack toward the pitch point.
