knuckle joint design and calculations
Knuckle joints may be cast or fabricated or forged. In the knuckle joint illustrated, the rods are integral with the eye and fork (forged construction). However, the knuckle joint is often separate to the rods, and the rods need to be welded or screwed into the eye and fork. In the knuckle joint illustrated, there is no separate bearing and rotational or motion occurs between the pin and eye or pin and fork or both. If there is considerable movement, it may be necessary to use bearings to minimise friction and wear. If this is the case, the pin is usually a tight fit in the eye or held to the eye with a grub screw and bearings are provided in the fork. The bearings may be plain bearings or rolling element bearings.
