Patent number: 7168879Abstract: 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: GrantFiled: May 28, 2003Date of Patent: January 30, 2007Assignee: Bollhoff GmbHInventors: Andreas Bertram, Rainer Süssenbach

Patent number: 7134801Abstract: There is provided a ball joint provided with a ball stud having a spherical head portion in an end portion, a ball seat to which the spherical head portion is slidably fitted, thereby pivoting the ball stud universally, and a housing receiving the ball seat, the housing being structured such that a closed-end cylindrical main body portion and a flange portion extending outward in a radial direction from an edge portion of the main body portion are formed in accordance with sheet metal processing. The flange portion is formed thinner than a thickness of the main body portion.Type: GrantFiled: April 3, 2002Date of Patent: November 14, 2006Assignee: NHK Spring Co., Ltd.Inventor: Shigeru Kuroda

Patent number: 7114599Abstract: A protective sleeve made of an elastic material for a piston-cylinder unit with a piston disposed in a cylinder bore in an axially displaceable manner. The protective sleeve is provided with annular end segments that can be supported on the outer piston wall on one side and in the cylinder bore on the other. A middle segment of an essentially hollow cylindrical shape connects the two end segments with each other and, when the piston is in an entered position, is folded like a rag in a radial direction as in a bellows. To ensure reliable and correct folding of the protective sleeve during the entry of the piston, the middle segment is subdivided in the axial direction into annular longitudinal segments, the lengths of which are approximately equal to the length of a fold wall, and at least one of the longitudinal segments is provided with an essentially annular stiffening zone.Type: GrantFiled: February 9, 2005Date of Patent: October 3, 2006Assignee: Carl Freudenberg KGInventor: Eckhard Schneider

Patent number: 7090424Abstract: A ball-end pin with plastic flange is employed in steering or suspension systems of automotive vehicles, manufactured in two discrete parts, namely, the ball-end pin itself and the flange. The flange is made of plastic material by injection process, one providing its external circumference with a channel for the fixing of the smaller diameter opening of the protection cover of the ball joint, and it may be injected directly on the ball-end pin or injected separately, in which case its central orifice must have a certain conical shape and longitudinal protrusions. The ball-end pin is constructed by stamping process and during the process the same will be provided with a conical section with longitudinal grooves that eliminates the use of the machining process.Type: GrantFiled: July 9, 2002Date of Patent: August 15, 2006Assignee: Dana Industrial S/AInventor: Heitor Teofilo Barbosa

Patent number: 6966559Abstract: A process for forming the ball and socket joint with bellows seal (10), a bellows seal (10) and a ball and socket joint with bellows seal (10) is provided including a ball pivot pin (36, 38) with a connection piece (40). The sealing bellows is provided with an annular engagement surface (16) with a cavity (20). The connection piece with a sealing face is connected to the ball pivot pin. Lubricant (22) is disposed in the cavity prior to assembly of the ball and socket joint. The annular engagement surface (16) is provided in contact with the sealing face upon assembly to cause an amount of lubricant (22) to be squeezed out of the cavity (20).Type: GrantFiled: July 22, 2004Date of Patent: November 22, 2005Assignee: ZF Lemförder Metallwaren AGInventors: Markus Fischer, Eric Holmes, Daniel Dearing
