Problems solved by technology

This method eliminates any gaps between the shell and support, but limits the shell material to relatively low strength zinc or aluminum die-cast materials so that the resin support is not melted during casting

Embodiment Construction

[0060] refer to figure 1 with figure 2 A ball joint 14 is provided in the suspension element 12 to provide a suspension member 10, such as a control arm or tie rod joint. The ball joint 14 includes a housing 16, which may be made of steel. The ball 18 has a post 20 extending therefrom, which typically includes a threaded end for securing the ball joint 14 to another suspension component, such as a knuckle. In this example, a single linear bore 28 extends through the ball 18 and post 20 and is blocked by a plug 68 . The outer surface of the ball 18 is spherically shaped to allow the ball 18 to pivot and articulate within the inner bore 52 of the housing 16 .

[0061] In a two-piece housing construction, cover 24 forms another part of the housing structure and is secured to one end of bore 52 , for example by welding, to enclose and capture ball 18 within housing 16 . A support 22 composed of a material such as acetyl is injection molded into the space between the ball 18 a...

Abstract

A ball joint includes a stud extending from a ball. A housing has a bore that receives the ball. The housing has an interior surface facing the ball that includes a groove. A plastic bearing is arranged between the ball and the housing. The plastic bearing has first and second sides opposite one another. The first side has a spherical surface engaging the ball. The second side has a protrusion opposite the spherical surface that is received in and fills the groove and a recess in the spherical surface opposite the protrusion.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to U.S. Provisional Application No. 62 / 546,091, filed August 16, 2017, and U.S. Provisional Application No. 62 / 681,990, filed June 7, 2018. technical field [0003] The present disclosure relates to ball joints, for example, for vehicle suspension or steering components. Background technique [0004] Ball joints are commonly used in vehicles for suspension or steering elements, such as control arm or tie rod joints. Ball joints provide a connection that allows one element to rotate relative to the other while allowing articulation during the series of motions that a vehicle experiences during operation. [0005] One example ball joint configuration provides a preformed plastic support cup into which a ball is inserted in a snap fit relationship. The subassembly is then inserted into the bore of the housing and the cover is placed on the support. [0006] It is important to provide co...
