Publication number: 20080089738Abstract: In a ball joint 10, when a ball stud 11 rotates about its center axis L, at the beginning of the rotation, a ball seat 12 can be elastically deformed in the rotational direction, whereby the rotational torque can be gradually increased as the rotational angle increases. In a region of the ball seat 12 where slits S are provided, the frictional engagement force between a spherical head portion 11a of the ball stud 11 and the ball seat 12 is made greater than the frictional engagement force between the ball seat 12 and the ball socket 13. Therefore, when the ball stud 11 rotates about its center axis L, the ball seat 12 elastically deforms in the rotational direction before the spherical head portion 11a starts to slip in relation to the ball seat 12 in the region where a lager fiction engagement force is generated.Type: ApplicationFiled: September 7, 2005Publication date: April 17, 2008Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventor: Kotaro Shima

Patent number: 7249893Abstract: A rolling bearing and a rod end bearing are provided with a tilt mechanism and a rotary mechanism that are mutually independent. The tilt mechanism has a non-lubricated type spherical sliding bearing structure. The rotary mechanism has a rolling bearing structure which may or may not be sealed. By means of the non-lubricated type spherical sliding bearing structure, a tilt of the shaft center is made possible, and by means of a sealed rolling bearing structure, problems such as a lubrication oil leak are avoided, and carrying out high speed rotation and continuous rotation become possible. Because the sealed rolling bearing structure of the rotary mechanism does not call for a shaft center tilt function at all, the material of the seal can be chosen such that it emphasizes sliding resistance and high durability.Type: GrantFiled: February 21, 2003Date of Patent: July 31, 2007Assignee: Minebea Co.

Patent number: 6742955Abstract: A tie rod end having a purgative zerk for removal of used lubricants is provided. In one embodiment of the invention, the tie rod end includes a socket member that defines a first bore in which a ball stud member is disposed and a second bore in communication with the first bore. The purgative zerk is disposed in the second bore. In a second embodiment of the invention, the purgative zerk is disposed in a plug used to close one end of the first bore. The use and location of the purgative zerk enable purge holes to be eliminated from a boot seal disposed at one end of the first bore thereby reducing contamination of the tie rod end.Type: GrantFiled: September 26, 2001Date of Patent: June 1, 2004Assignee: Dana CorporationInventor: David G.

Patent number: 6733200Abstract: A construction of a cover for ball joint for application in connections of both angular and rotational movements of automotive vehicles. The cover is constructed with a boss in its outermost circumference so that when assembling the ball joint, the bearing flange that is inserted in the interior of the box, that is closed by the cover, does not burst. Moreover, the bearing is maintained fixed to the assembling place as it is desired, for the perfect operation of the ball joint. The cover constructed in this manner functions as a limiting piece in the assembling process, so that, even if too strongly pressed upon the bearing flange, it may burst only the outermost part of the bearing flange preserving its major part, that will be retained between the recess provided in the interior of the ball joint box and the space immediately posterior to the boss constructed in the outermost circumference of the cover, thus keeping the bearing fixed to its place.Type: GrantFiled: June 28, 2002Date of Patent: May 11, 2004Assignee: Dana Industrial S/AInventor: Marisa Ueno

Publication number: 20040086324Abstract: A plug-in coupling for removably interconnecting a first structural member and a second structural member comprises a resiliently deformable female coupling part adapted to be inserted into a socket at the first structural member such that it is retained therein. The female coupling part comprises a ball-shaped cup, an intermediate annular wall integral with said ball-shaped cup and serving as a guide portion, and a tubular external wall integral with said annular intermediate wall. The external wall surrounds at least a part of the ball-shaped cup in spaced relation thereto and engages a peripheral wall of the socket when the female coupling part is inserted into the socket. A male coupling part comprises a ball-shaped head and a fixing portion for securing the male coupling part to the second structural member. The intermediate annular wall of the female coupling part is of an undulated shape at least in a certain area thereof.Type: ApplicationFiled: May 28, 2003Publication date: May 6, 2004Inventors: Andreas Bertram, Rainer Sussenbach

Patent number: 6726394Abstract: The invention relates to a connecting ball joint (10), for example an anti-roll bar of a running vehicle, the ball joint (10) comprising a straight support (20) running along a general axis of elongation (xx′) and an elastically deformable member (30) mounted around the support (20). The ball joint has the characteristic that its elastically deformable member (30) comprises at least one laminated structure (35; 135) made up of (a) layer(s) (32) of elastically deformable flexible material and of (a) layer(s) (34) of more rigid material.Type: GrantFiled: October 17, 2001Date of Patent: April 27, 2004Assignee: HutchinsonInventors: Denis Garnier, Laurent Beaubatie

Patent number: 6702502Abstract: A ball-and-socket joint, preferably for motor vehicles, in which a joint ball formed on a pivot pin is mounted movably in a bearing shell consisting of a plastic, is presented. The bearing shell has recesses accommodating lubricant on its inner jacket surface facing the joint ball and is itself inserted into a housing. According to the present invention, the recesses may be grooves as a structural system with groove sections or depressions of microscopic size extending obliquely in relation to the central longitudinal axis of the ball-and-socket joint. Due to this novel design, a pumping effect is achieved during movements of the joint ball over the groove sections, and this pumping effect draws the lubricant present in the groove sections into the gap between the joint ball and the bearing shell, so that improved lubrication of the ball-and-socket joint compared with the state of the art is guaranteed under all operating conditions.Type: GrantFiled: April 11, 2001Date of Patent: March 9, 2004Assignee: ZF Lemförder Metallwaren AGInventors: Jürgen Gräber, Werner Stehr

Patent number: 6676325Abstract: A pivot socket of the present invention incorporates a stud shaft component having a tapered head portion disposed within a housing cavity, and an axial pin extension extending upward into the cavity therefrom. The tapered head portion seats against a tapered bearing surface disposed within the housing cavity, and the axial pin extension is enclosed within a resilient bushing. During use, lateral and axial loads imparted on the stud shaft are transformed into radial and axial component forces at the bearing surfaces. Angulation loads are resisted by the tapered head portion, and converted to axial forces. The radial force components are distributed to the interior walls of the housing cavity, while the axial force components are transferred axially through the resilient bushing to the end closure components secured to the housing, or directly to the housing through the tapered bearing surface.Type: GrantFiled: May 15, 2002Date of Patent: January 13, 2004Assignee: Federal-Mogul World Wide, Inc.Inventors: George R.
