Abstract: A support for an eccentric of an adjusting arrangement of a connecting rod has a piston rod (18) guided by a piston (20). A seal (24) is connected to the piston (20) in a supporting cylinder (12, 14) in the connecting rod (2) and has a longitudinal axis (16). The piston (20) encloses a chamber (22) with the supporting cylinder (12, 14). The piston (20) has a lower part (30) arranged on an upper part (28) for movement along the axis (17) of the supporting cylinder (12, 14). An expanding ring (40) between the upper and lower parts (28, 30) interacts with faces (42, 44) of the lower part (30). The upper part (28) spreads the expanding ring (40) as the spacing between the faces (42, 44) is reduced, and the expanding ring (40) applies a friction force FR on an inner wall (46) of the supporting cylinder.

Abstract: A shifting gate arrangement, and a method of production thereof, having shifting gates, which are adjustable in a spatial direction, for actuating connecting rod adjustment provisions, which are integrated in connecting rods, for the purpose of changing the length of the respective connecting rod. A sheet metal support frame is mounted so as to be displaceable to and fro in the one spatial direction. The shifting gates are fixedly connected to the support frame and are designed as a cast part or sintered part.

Abstract: An apparatus for adjusting the length of connecting rods in an internal combustion engine, having a shift guide plate arrangement which has shift guide plates which can be adjusted in one spatial direction for actuating connecting rod actuating devices which are integrated into the connecting rods for the purpose of changing the length of the respective connecting rod. The shift guide plates are connected fixedly to a carrier frame. The carrier frame is mounted in a stationary oil scraper arrangement such that it can be displaced in the spatial direction. The oil scraper arrangement has oil scrapers for stripping oil from the connecting rods.

Abstract: An assembly with a combustion engine and an electric machine, which are coupled with each other by way of a planetary gear train, employs a claw clutch or a toothed clutch, in particular as a brake, between a ring gear of the planetary gear train and a housing of the combustion engine. For this purpose, rotation speeds of the electric machine and the combustion engine set commensurate with a fixed gear ratio, and the brake is closed after the set rotation speeds have been attained with a predetermined minimum accuracy. In this way, machine elements which are compact and operate with insignificant wear, such as claw clutches or toothed clutches, can be employed as the clutch or brake.

Abstract: In an assembly with a planetary gear train, which includes the elements sun gear, planet carrier with planetary gears and ring gear, two elements, in particular the sun gear and the planet carrier, are coupled with each other via an overrunning clutch. A clutch bridges the overrunning clutch. Bridging is discontinuous and controlled by a control device based on the relative rotation of the two elements to be coupled. For example, one rotation speed sensor can measure the rotation speed of an electric machine, whereas another rotation speed sensor can measure the rotation speed of a crankshaft of an combustion engine. In a motor vehicle, the combustion engine can be coupled with an electric machine, using different gear ratios during startup or boosting and in generator operation. In addition, the electric machine can drive an air-conditioning compressor when the combustion engine is not running.
