Abstract

A link assembly for a vehicle control system comprising a spacer molded of glass-filled nylon and a socket housing mounted on each end of the spacer, both socket housings also being molded of glass-filled nylon. Each housing comprises a male socket component and a female socket component which are mirror-image, identical to each other except for complementary male locator protrusions and female locator depressions formed in opposing relationship on mating faces of respective components. The components are ultrasonically welded together to capture opposite ends of the spacer and the ball ends of respective ball studs.

Claims

1. A link assembly for a vehicle control system, comprising:

(a) a plastic spacer molded in one piece;

(b) said spacer including an elongated body and a mounting element on at least one end said body;

(c) said mounting element including a mounting pin extending axially from said elongated body and an enlarged head on the end of said pin, said head being polygonal in cross-section;

(d) a ball socket housing seated on said one mounting element;

(e) said ball socket housing including a first socket component and a second socket component, said socket components having opposed inner faces;

(f) said first and second socket components each including a collar adjacent one end and a socket adjacent the other end;

(g) a well formed in each of said collars, each said wells having a polygonal cross-section;

(h) said first and second socket components being mated at said opposed inner faces so as to enclose said polygonal cross-section head in said wells.

2. The link assembly of claim 1 further characterized in that:

(a) each of said wells is rectangular in cross-section; and

(b) said head has a substantially square cross-section;

(c) whereby said spacer can be connected to said housing in any of four radial orientations.

3. The link assembly of claim 1 further characterized in that:

(a) said spacer body comprises a central core and a plurality of ribs radiating therefrom;

(b) and end cap formed on said one end of said core;

(c) said mounting element extending from said end cap.

4. The link assembly of claim 1 further characterized in that said spacer and said socket component are molded from glass-filled nylon.

5. A link assembly, comprising:

(a) a plastic spacer molded in one piece;

(b) said spacer including an elongated body and a mounting element on each end of said body;

(c) each of said mounting elements including a mounting pin extending axially from said elongated body and an enlarged head on the end of each pin, each of said heads being substantially square in cross-section;

(d) a ball socket housing seated on each of said mounting elements;

(e) each of said ball socket housings including a first socket component and a second socket component, said socket components having opposed inner faces and being molded of plastic;

(f) each of said first and second socket components in each housing including a collar adjacent one end and a socket adjacent the other end of the component;

(g) a well formed in each of said collars, each well having a substantially rectangular cross-section;

(h) said first and second socket components in each housing being mated at said opposed inner faces so as to enclose a corresponding square cross-section head of said spacer in said wells of the corresponding housing.

6. The link assembly of claim 5 further characterized in that:

(a) said spacer has a centerline which runs longitudinally through the center of each pin;

(b) said socket components being mated on said centerline.
