Embodiment Construction

[0019] An arrangement 16 is coupled to an engine 10 comprising a crankshaft 12 which is caused to turn by the movement of a reciprocating piston within a combustion chamber 14, the arrangement comprising a planetary transmission connected to a pulley 18 and having a damping unit 20. The pulley 18 is used to connect a motor 22 via a belt drive 24, the motor includes a pulley 26 which can be rotated by a rotor (not shown) of the motor 22 via a shaft 28.

[0020] The planetary gear comprises a sun gear 30 which is connected to the pulley 18 and meshes with planet gears 32 which are connected to one another via a planet gear carrier 34 . An overrunning clutch 35 is arranged between the planet carrier 34 and the sun gear 30 . The planet carrier 34 is coupled to the crankshaft 12 via a flange 36 . The flange is screwed to the crankshaft 12 via an axial bolt 38 . At the same time, a support plate 40 is clamped between the flange 36 and the crankshaft 12 , on which a rubber ring 32...

Abstract

The invention refers to an arrangement, comprising an engine in connection with a planetary gear, wherein a damping unit (12) for attenuation or vibration attenuation of a crankshaft (12) of the engine (10) is provided. The damping unit makes vibration far from the planetary gear. A carrier part (40) is connected with the crankshaft (12) at a position as follows, which lies closer to a combustion chamber (14) of the engine (10) than the a connecting member (36) does which connects the crankshaft with the planetary gear.

Description

technical field [0001] The invention relates to an arrangement / plant comprising an engine coupled in a specific manner to a planetary transmission. Background technique [0002] Usually, such an arrangement is used to connect the engine via a planetary gear and optionally via a further drive, such as a belt drive, to an electric machine that can be used as a starter for the engine and at the same time as a generator. To connect the planetary gear, one of the sun gear, planet carrier and ring gear, preferably the planet carrier, is connected to the crankshaft of the engine, to be precise via a connecting element, generally a flange, which Connects to the far end of the crankshaft with reference to the combustion chambers of the engine. [0003] Both DE 101 48 961 A1 and DE 198 22 426 C2 disclose that a vibration damper for crankshaft vibrations is integrated in this arrangement. Such a vibration damper has a so-called damping mass, ie a damping body, which absorbs and damps...
