US Patent:

6371682, Apr 16, 2002

Filed:

May 26, 2000

Appl. No.:

09/579647

Inventors:

Garth B. Maughan - Delta OH

Assignee:

Dana Corporation - Toledo OH

International Classification:

F16C 1100

US Classification:

403165, 403147, 280 93508

Abstract:

A non-articulating joint assembly is disclosed having a bracket with a first generally cylindrical end that is received in a split-half bearing assembly that has a tapered outer surface. The tapered split-half bearing assembly matingly engages a tapered bore in the first housing of a socket. The tapered split-half bearing is slightly larger than the tapered inner bore to provide a radial pre-load on the assembly bearing. A cap bearing is located in the housing and engages the bottom surface of the tapered split-half assembly bearing. A closure member is located below the cap bearing and cooperates with a spring member and a rim of the first housing that is crimped over to securely hold the components in position and also provide an axial pre-load on the split-half bearing. Similarly, a second housing on the socket member has a second split-half bearing assembly and a second cap bearing assembly that receives a stud is provided. The stud includes a generally cylindrical end portion.

Garth B. Maughan - Delta OH

Assignee:

Dana Corporation - Toledo OH

International Classification:

F16C 1106

US Classification:

403135, 403 39, 280 93511

Abstract:

An improved socket liner for a ball and socket joint is adapted to be fixedly installed within a joint housing so as to encase the ball. The housing defines a longitudinal axis, and the liner, formed in two longitudinally extending mating halves that confront one another along surfaces parallel to the axis of the housing, are oriented to provide a theoretically tightest possible ball bearing-socket fit. Each liner half includes at least one protuberance on each longitudinally confronting surface. The protuberances not only facilitate location of the liner halves during assembly, but also assure a physical separation between the halves, creating an additional lubrication groove for enhanced operation of the joint during its useful life. In one preferred form, a compliant thin soft material cover is overmolded over the exterior socket liner structure, and exterior surface slots integrally provided on the cover interlock with protruding ribs fixed to the interior of the housing.

International Classification:

F16J 1552

US Classification:

277635, 277637, 464173, 464175, 403134

Abstract:

The invention relates to an improved dust cover a ball and socket joint. The dust cover includes an elongated sleeved body portion and a hinged portion. The sleeved body portion is constructed of a flexible, elastomeric material and is sized such that the sleeved body portion must be stretched over a joint housing to frictionally engage an exterior side wall of the joint housing without requiring any additional fasteners. The hinged portion includes a sealing lip that seals around a shank of a ball stud and a plurality of hinges that provide additional surface material for the dust cover for increased flexibility. The dust cover includes at least three hinges, a first upper hinge, a second upper hinge and a lower hinge positioned therebetween. The first upper hinge is offset from the second upper hinge such that the first upper hinge is positioned higher than the second upper hinge. The offset serves to distribute planar and torsional twisting along the hinged portion for increased flexibility of the dust cover.

Abstract:

An aftermarket retrofit kit is used to prepare control arm bosses of automotive suspension systems to receive new, replacement ball joints. The kit includes a special cutting tool for forming obtuse threads in the apertures of aluminum suspension system mounting bosses for replacement of spent or used steel ball joints originally pressed-fit into forged aluminum control and steering arms. Since unthreaded apertures of bosses of control and steering arm joints in which the original pressed fitted equipment ball joints may be threaded to receive the new joints, avoidance of having to replace expensive original control and steering arms is made possible by the reuse of such arm parts normally discarded. A separate alignment block is included to assure accurate piloting of the cutting tool. Threading of the control arm bosses can be done on or off of the vehicle, and separate kits are provided for upper and lower control arms.

International Classification:

F16J 300

US Classification:

277635, 277636, 464175

Abstract:

An improved dust boot accommodates a ball and socket joint subject to high articulation under harsh environmental conditions of moisture and corrosive contaminants. The improved boot is capable of accommodating articulation of an associated ball stud up to 60 degrees from the rotational center of the joint, as well as twisting motions of the stud of at least 45 degrees. The dust boot includes multiple undulations that feature a series of convolutions or deep folds. In one example, the boot contains at least one undulation that includes two pairs of radially extending ribs so as to present a fully convoluted bulbous loop, complete with reverse bends to maximize amount of material available for stretching when the stud is articulated to high angles. The bulbous loop not only provides for up to 60 degrees of stud articulation but also provides at least 45 degrees of twisting motion without potential deleterious effects.

Garth Maughan - Delta OH

Assignee:

Dana Corporation - Toledo OH

International Classification:

F16C 1106

US Classification:

403137

Abstract:

A bearing set for a ball and socket joint comprises an outer sleeve with an upper cavity and a lower cavity, each of the cavities defined by an inner skirt, an upper bearing received in the upper cavity and a lower bearing received in the lower cavity. A compression pre-load is applied when each of the bearings is inserted into its cavity, a cylindrical outer wedge surface of the respective bearing having a greater diameter than a corresponding diameter of the corresponding skirt. The bearing set is subjected to additional compression pre-load when the bearing set and ball stud are inserted into a housing and the housing is closed.

International Classification:

F16C 1100

US Classification:

403133

Abstract:

A motor vehicle ball joint assembly includes a ball stud having a ball stud axis with a shank portion and a ball end centered thereon. A bearing liner has an open end disposed over the ball end with the open directed toward the shank portion. The bearing liner has a bearing surface engaging the ball end. A plurality of slits extend from the open end of the liner, defining a plurality of flex members. The flex members operably deflect to receive the ball end. When the ball end is completely inserted in the liner, the flex members return to a locked position, axially retaining the ball end in the liner. A stem engaging element has a stem axis and extends radially from the bearing liner. The stem engaging element has metal engaging threads. A rigid plastic case envelopes the bearing liner.
