Knuckle-supported wheelend assembly with improved shaft-hub interface |
摘要 |
A knuckle-supported wheelend assembly includes a shaft having a contoured peripheral surface portion proximate to an outboard end featuring a minimum radius and a maximum radius, and a hub mounted on the shaft's contoured surface portion via a complementary, contoured central bore. The nontapered contoured hub-shaft interface includes a slight twist or jog to reduce backlash and to permit a relative shortening of the length of axial hub-shaft engagement to as little as about 45% of the maximum radius, thereby advantageously reducing scrub radius for a given wheel-tire combination. By eliminating any required taper of the contoured interface, the hub's inboard face firmly abuts the machined face of the inner race of a knuckle-mounted, shaft-supporting bearing assembly to achieve reduced assembly runout. The hub's wheel-mounting face and integral annular friction surfaces are each machined with reference to the inboard hub face to ensure a high degree of parallelism.
