Patent number: 10184408Abstract: A device for changing a compression ratio of a cylinder unit of a reciprocating piston internal combustion engine has an eccentric bushing which is rotatably arranged in a bore of a connecting rod eye. Said eye encloses a crank pin of a crankshaft, and the bushing is rotatably guided in the bore and can be locked via locking openings, which are arranged to be offset from each other by preferably approximately 180°. The connecting rod has a locking apparatus which interacts optionally with the locking openings and via which the eccentric bushing can only ever be transferred from one position to the next. The locking apparatus has a sliding guideway extending parallel to the longitudinal axis of the bore of the connecting rod bearing eye. The sliding guide interacts with actuating pins arranged in the locking openings and can be displaced radially with respect to the bushing.Type: GrantFiled: June 16, 2015Date of Patent: January 22, 2019Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 10087834Abstract: A device for changing a compression ratio of a cylinder unit of a reciprocating piston combustion engine is provided. An eccentric bushing is rotatably arranged in a receiving bore hole of a bearing eye of a connecting rod (“conrod”). The conrod bearing eye is formed by a conrod upper part and a conrod lower part, and which surrounds a crankpin of a crankshaft. In addition, the eccentric bushing is rotatably guided in the receiving bore hole and can be locked preferably in two positions which are offset from one another by approximately 180° in the circumferential direction of the eccentric bushing. In order to achieve a targeted rotation of the eccentric bushing in the bore hole of the conrod bearing eye between the locking positions, a freewheel is arranged between an outer casing surface of the eccentric bushing and the receiving bore hole of the conrod bearing eye.Type: GrantFiled: June 16, 2015Date of Patent: October 2, 2018Assignee: SCHAEFFLER TECHNOLOGIES AG & CO.

Patent number: 8459424Abstract: A freewheel clutch which has rollers arranged between an inner and outer ring. One of the rings has ramps that interact with the rollers. Each roller is spring-loaded against a ramp by a leaf spring. Each spring is held on a web of a cage by a U-shaped section that encompasses the web. The spring has a securing section connected to the U-shaped section that extends tangentially, limits mobility of a roller in a first radial direction, and is connected to a U-bottom of the U-shaped section. An end section of a U-leg facing away from the U-bottom is bent from the U-leg, forming a second securing section, which limits mobility of the roller in the second radial direction. An extension of the end section facing the U-bottom engages the web such that the spring is held on the web radially by the U-bottom and extension of the end section.Type: GrantFiled: April 21, 2010Date of Patent: June 11, 2013Assignee: Schaeffler Technologies AG & Co.

Patent number: 8256594Abstract: A freewheel cage, which has a basic body with two annular, substantially radially extending edge disks that are connected to one another by a plurality of axially running connecting pieces and at least one annular component for fastening the basic body to a freewheel. The connecting pieces are adjacent to one another in the circumferential direction so as to form intermediate spaces for at least partially holding clamp bodies. The annular component is formed as a separate component arranged on at least one of the edge disks. By design, the basic body for the freewheel cage is produced with reduced expenditure, and subsequently, the annular component for fastening the basic body to a freewheel can, as a separate component, be produced, and arranged on the basic body for fastening to a freewheel with likewise correspondingly reduced expenditure.Type: GrantFiled: August 14, 2009Date of Patent: September 4, 2012Assignee: Schaeffler Technologies AG & Co.
