Patent number: 11041522Abstract: A joint for a vehicle, the joint having an outer sleeve, a joint shell for receiving a movably supported joint inner portion, and an inner sleeve, at least part of which is arranged between the joint shell and the outer sleeve. The inner sleeve has two radially outwardly projecting rim cylinders which are axially mutually spaced and run around the outer periphery of the inner sleeve, and the two rim cylinders define a peripheral recess on the outer periphery of the inner sleeve. The joint is characterized in that a press-fit device designed integrally with the inner sleeve extends in the region of at least one rim cylinder of the inner sleeve radially outwards beyond the outer diameter of the rim cylinder.Type: GrantFiled: November 15, 2017Date of Patent: June 22, 2021Assignee: ZF FRIEDRICHSHAFEN AGInventors: Klaus Broeker, Monnic Hoenke

Publication number: 20080145141Abstract: A joint and/or bearing arrangement (1) has a pivot (2) with a separate joint head (4) part, which can be held thereon and surrounds the pivot (2) in some areas. At least one equalizing channel (15) connects a space (13) located between the joint head (4) and a surrounding joint shell (5) to a space (14) located on the other side of the joint head (4) in respect to the radial extension of the pivot (2).Type: ApplicationFiled: September 7, 2005Publication date: June 19, 2008Inventors: Klaus Broeker, Jens Bach

Patent number: 7357591Abstract: A ball-and-socket joint has a pivot pin accommodated rotatably and tiltably with a spherical joint area in a bearing shell. The bearing shell is in turn arranged in the recess of a joint housing. A closing ring fixes the bearing shell in the joint housing in the axial longitudinal direction of the pivot pin by at least one surface pair. Corresponding to a first solution variant, an intermediate element made of an elastic material may be arranged between the corresponding contact surfaces of the surface pair on the bearing shell and the closing ring. As an alternative an insert element may be arranged between the outer contour of the bearing shell and the bottom area of the recess, wherein at least one intermediate element made of an elastic material is arranged between the outer surface of the insert element and the corresponding inner surface of the recess.Type: GrantFiled: January 9, 2003Date of Patent: April 15, 2008Assignee: ZF Lemförder Metallwaren AGInventors: Klaus Bröker, Helmut Noe

Patent number: 6821047Abstract: A ball-and-socket joint (1) is provided with a housing (2) closed by a cover (3), with a bearing shell (5, 6) and a joint ball (4) accommodated therein rotatably and tiltably with a ball pivot. The bearing shell (6) provided with projections and offsets on its outside as well as an entropy-elastic, pretensioned spring element (7) are fixed by the cover (3) in the housing (2). The bearing shell is formed by lower and upper bearing shells (5, 6), both of which are closed, and the lower bearing shell (5) extending partially over the upper bearing shell (6) is provided on its overarching inside (5b) and the upper bearing shell (6) is provided on its outside (6a) with the projections and offsets (20, 21; 11, 12) with which the entropy-elastic spring element (7) cooperates in a positive-locking and/or non-positive manner under the action of the cover (3) in its closed position and nonrotatably couples the two bearing shells (5, 6) with one another.Type: GrantFiled: January 16, 2003Date of Patent: November 23, 2004Assignee: ZF Lemförder Metallwaren AGInventor: Klaus Bröker

Patent number: 6773196Abstract: A joint housing (1) has a housing recess (2), a pivot pin (4), mounted in the housing recess. The pivot pin has a joint ball (3) provided with a surface protection. A pin section protrudes from a housing opening (18), with a bearing shell (5) arranged between the joint housing and the joint ball, and with a closing ring (7), which closes the housing recess of the joint housing and tensions the bearing shell arranged therein in the joint housing. The closing ring follows essentially with its inner contour the outer contour of the bearing shell due to a bevel or a radius formed. The closing ring (7) to be inserted into the joint housing is fixed in its position in the joint housing (1) and has a sealing lip (17) which is in contact with the joint ball (3) under elastic pretension on the side of the housing opening (18) through which the pin section of the pivot pin (4) protrudes from the joint housing (1).Type: GrantFiled: July 24, 2002Date of Patent: August 10, 2004Assignee: ZF Lemförder Metallwaren AGInventors: Klaus Bröker, Martin Rechtien, Wolfgang Kleiner, Reinhard Buhl

Patent number: 6688799Abstract: A ball-and-socket joint is provided with a joint housing which is open on at least one side with a housing recess, with a joint pin mounted in the housing recess with its joint ball provided with a surface protection. A pin section projects from a housing opening. A bearing shell is arranged between the joint housing and the joint ball. A sealing bellows is provided between the joint housing and the joint pin. A sealing element, which is under elastic pretension in sliding contact with the joint ball, is arranged between the joint housing and the joint ball.Type: GrantFiled: September 28, 2001Date of Patent: February 10, 2004Assignee: ZF Lemforder Metallwaren AGInventors: Klaus Bröker, Reinhard Buhl, Wolfgang Kleiner, Martin Rechtien

Patent number: 6302615Abstract: A ball-and-socket joint preferably for vehicle suspensions or steerings of motor vehicles with a joint housing, with a housing cover closing the joint housing on one side, and with a pivot pin, which is mounted rotatably and deflectably in at least one bearing shell using a spherical bearing surface, is described. The bearing shell is in turn stationarily fixed in the joint housing and an elastic buffer element (6) is arranged on the outside of the joint housing (3) facing away from the pivot pin (1).Type: GrantFiled: December 10, 1998Date of Patent: October 16, 2001Assignee: ZF Lemforder Metallwaren AGInventors: Wolfgang Kleiner, Klaus Bröker
