Abstract: 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.

Abstract: 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.

Abstract: A flanged freewheel (1) with an outer ring (2) which is configured as an angled flange part and which has an axially oriented ring flange (5) that forms a running surface (7) for clamping elements and a radially oriented flange area (3) for attaching the flanged freewheel (1). In order to retain or improve the strength of the outer ring (2)—despite a reduced wall thickness (x)—a ring collar (13) that faces radially inwards is provided at the free end face (12) of the ring flange (5).

Abstract: The present invention relates to a clamping body freewheel including an inner part having a circular cylindrical outside circumference, an outer part having a circular cylindrical inside circumference, and clamping bodies, which are accommodated in a gap formed by the inside circumference and the outside circumference and are arranged consecutively in the circumferential direction in a tiltable manner and are guided in openings of a cage, where the clamping bodies are arranged in a radially inwardly open sleeve, and the clamping body freewheel is introduced in the outer part by means of the sleeve in a rotationally fixed manner, and a track is formed on an inside circumferential surface of the sleeve for the clamping bodies.

Abstract: The invention relates to a free-wheeling cage having a basic body, wherein the basic body includes a first cage ring and a second cage ring, which are arranged around a common axis and wherein cage webs extend axially between the two cage rings, whereby cage pockets are formed, wherein the basic body includes a lubricant reservoir which allows a metered dispensing of lubricant.

Abstract: 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.

Abstract: 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.

The means is formed as at least one separate component is arranged on at least one of the edge disks. By this design, it is obtained that the basic body for the freewheel cage is produced with reduced expenditure, and subsequently, the means 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.

Abstract: The present invention broadly comprises a stator and clutch assembly for a torque converter including first and second halves for a stator, each formed from first and second single pieces. Blades for the stator are disposed within respective annuli for the first and second halves. The assembly also includes a one-way clutch. The first and second halves have inner circumferential portions configured to form a portion of the clutch. The assembly includes an axially displaceable plate connected to a hub. The plate and a circumferential portion are operatively arranged to form a portion of the clutch. In some aspects, the plate and the circumferential portion are arranged to lockingly engage and the assembly includes a displacement element arranged to urge the plate toward the circumferential portion. In some aspects, the plate and hub are formed from a single piece or the plate is axially displaceable with respect to the hub.
