Patent number: 8925505Abstract: A finger follower lever of a valve train, which has a lever body that is a pressed and punched component made of sheet metal and has a U-shaped cross-section with two largely parallel side walls. A roller rotatably mounted between the side walls on a pin. The pin is uniformly hardened and inserted at each end into a hole punched out of the side wall and is staked or caulked at the ends. To enable the holes to be punched out simultaneously in opposite directions of a relatively narrow lever body, at least one of the two side walls has, at least on the outside thereof, a flat recess in the region of the hole.Type: GrantFiled: April 13, 2012Date of Patent: January 6, 2015Assignee: Schaeffler Technologies AG & Co.

Patent number: 8656878Abstract: A cam follower for actuating a gas exchange valve of an internal combustion engine. The cam follower has a housing and a cam roller mounted in a recess of the housing for disengaging a cam of a camshaft. The cam roller is mounted radially on a bearing journal by a needle bearing that extends in the bearing bore thereof. The width of the needle bearing is significantly greater than the width of the cam roller in the region of the cam disengagement. The width of the needle bearing is also significantly greater than the width of the cam roller in the region of the bearing bore and significantly greater than the clear space between roller contact surfaces which delimit the recess and on which the cam roller runs axially with the end faces thereof.Type: GrantFiled: November 26, 2010Date of Patent: February 25, 2014Assignee: Schaeffler Technologies AG & Co. KGInventor: Stephan Moeck

Patent number: 8584640Abstract: The invention relates to a finger follower, or lever (1) of a valve train, for example of a piston-type internal combustion engine, with a lever body (2) having an end-sided base web (4), on which there is a spherical cap-shaped bearing cup (8) for an articulated mounting on a bearing pin of a housing-sided support element, said bearing pin terminating as a spherical cap; and on this base web is fastened a retaining clamp (9), engaging with an annular groove of the bearing pin, in order to secure the finger follower (1) on the support element in such a way that said finger follower can move to a limited extent.Type: GrantFiled: April 5, 2012Date of Patent: November 19, 2013Assignee: Schaeffler Technologies AG & Co.

Publication number: 20120312264Abstract: A finger follower lever for actuating gas exchange valves of an internal combustion engine, having a lever body formed by two parallel side walls spaced apart by a transversely extending web. The web forms a first, joint socket end as a pivotable support for the lever, and a second end with a valve actuating surface. A cam roller is rotatably held between the side walls via a needle ring of a needle bearing. The cam roller projects partially via an aperture in the web for cam contact. The cam roller is narrow, and the needle ring projects beyond the cam roller at one axial end, and ends directly adjacent to a corresponding side wall. The aperture has a cross section defined by an overlap between a first, cam roller pocket with an extent corresponding to the cam roller in the axial direction, and a second pocket for the needle ring.Type: ApplicationFiled: June 4, 2012Publication date: December 13, 2012Applicant: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 8104441Abstract: A cam follower for a valve drive of an internal combustion engine. The cam follower has a housing and a cam roller. The cam roller is arranged between the side walls of the housing and is mounted on a journal which bridges the side walls. The cam roller, which has an outer ring, a rolling body set and an inner ring, is a combined plain and rolling bearing. The outer ring and the inner ring are in sliding contact with one another, and the rolling body set is arranged between the inner ring and the journal.Type: GrantFiled: July 24, 2009Date of Patent: January 31, 2012Assignee: Schaeffler KGInventors: Stephan Moeck, Michael Kress

Patent number: 7963261Abstract: A drive valve for an internal combustion engine comprising a variable hub profile for a valve having a lever supported on a variable support point by means of a switchable support element which provides possibilities for influencing the hub profile and alternatively and cumulatively, the cam is axially displaced such that various cam paths are active on the lever.Type: GrantFiled: June 29, 2006Date of Patent: June 21, 2011Assignee: Schaeffler KGInventors: Stephan Möck, Arndt Ihlemann

Patent number: 7721695Abstract: Connecting element (10) retains cam follower (2), which actuates gas-exchange valve (4) of an internal combustion engine, on support element (6). Support element (6) has spherical end (7) on cylindrical section (22) and on which cam follower (2) is mounted, so as to be pivotably movable in the direction of gas-exchange valve (4) about center of rotation (9). Connecting element (10) has elastically deformable projections (21), which proceed from central webs (19), parallel to the pivot axis of cam follower (2) such that connecting element (10) is connected to cylindrical section (22) in a frictionally-engaging manner. Projections (21) are embodied as lugs (20) which angle away from central webs (19) and extend in a direction pointing away from cam follower (2), so that projections (21) are elastic in shape.Type: GrantFiled: July 27, 2006Date of Patent: May 25, 2010Assignee: Schaeffler KGInventors: Stephan Moeck, Helmut Engelhardt

Patent number: 7146950Abstract: The invention proposes a connecting element (9) for retaining a lever-type cam follower (1), that serves to activate a gas exchange valve (5) of an internal combustion engine, inseparably on a support element (2) comprising a spherical end (7) on which the cam follower (1) is pivotally mounted through a concave depression (6). The connecting element (9) engages into an annular groove (8) under the spherical end (7). In a connecting element (9) of this type, a central portion (10) of the connecting element (9) bears against an underside (11) of the cam follower (1) oriented toward the support element (2) and forms, through two legs (12, 13) and a crossbar (14) connecting these legs (12, 13) to each other, a U-shaped recess (15) in longitudinal direction of the cam follower (1). This recess (15) engages around the groove (8) after the manner of a fork and orthogonally to a pivoting direction of the cam follower (1), substantially without lash.Type: GrantFiled: June 30, 2005Date of Patent: December 12, 2006Assignee: INA-Schaeffler KGInventors: Stephan Moeck, Helmut Engelhardt
