More particularly, the present invention relates to a device for retaining the kingpin against rotational movement within the axle hub, regardless of wear during its useful life.

車軸ボスの穴とを貫いて延び各部材を相互に保持する。In common front suspension systems for highway vehicles, such as trucks, the wheel spindles are connected to the front axle via a steering knuckle and kingpin member. The knuckle has a forked yoke that connects the knuckle to a fixed axle boss. A king pin also extends through each alignment hole in the yoke and the hole in the axle boss to hold the members together.

一層に一層低い負荷に適応するようにブシュを支える。The axle boss, also called the knuckle support boss, thus rotatably holds the kingpin but allows the knuckle to rotate. Roller bearings mounted between the knuckle support and the lower arm of the forked yoke permit low friction movement of the knuckle about the steering axis. The upper arm supports the bushing to accommodate even lower loads.

The space between the lower and upper arms of the knuckle yoke often does not fit precisely. The resulting gaps or crevices cause the parts to move relative to each other due to wear, especially after the useful life of the parts. In heavy-haul truck suspension systems, the kingpin is typically secured against rotation by a tension key with a tapered surface toward the side of the kingpin. However, as wear creates more clearance, The kingpin moves and oscillates within its associated knuckle hole during the useful life of each part. Such movement further exacerbates the wear problem.

- Form a (drawkey) system. In a preferred configuration, the assembly includes a transverse axle beam having a pair of upwardly oriented knuckle support bosses at each end. Each boss has vertically spaced ends and a hole extending through the ends. A steering knuckle is pivotally mounted to each boss by upper and lower arms having aligned holes. A cylindrical king pin extends through a hole in the boss and a hole in each arm to retain the steering knuckle to the boss.
