  • the multi-joint crank drive comprises the eccentric shaft whose rotation angle can be adjusted by means of an adjusting device, in particular as a function of an operating point of the internal combustion engine.
  • the multi-link crank drive has a number of coupling pistons corresponding to the number of pistons of the internal combustion engine, each of which is rotatably mounted on the corresponding crank pin of the crankshaft and has two arms protruding beyond the crankshaft on opposite sides and each having a pivot joint at its end.
  • One of the pivot joints is used for pivotal connection with the piston connecting rod, which connects one of the pistons of the internal combustion engine via the coupling member with the crankshaft.
  • Another of the pivot joints is used for pivotal connection with the so-called Anlenkpleuel, which is rotatably mounted with its other end on the crank pin of the eccentric shaft.
  • the compression ratio achieved in the cylinder assigned to the respective piston can be set, in particular as a function of the operating point of the internal combustion engine and / or the power stroke.
  • the eccentric shaft is brought into a specific, the desired compression ratio corresponding angular position.
  • the adjusting device is provided, by means of which the eccentric shaft is adjustable within the specific rotation angle range to an arbitrary angular position. This adjustment is usually controlled and / or regulated. Under The regulated setting is to be understood that the adjusting device is initially set and approached the desired angular position. Subsequently, the actual existing angular position of the eccentric shaft is checked. In the event of a deviation, the adjusting device is given a rotational angle position corrected by the deviation. This process is repeated until the actual rotational angular position of the eccentric shaft coincides with the desired rotational angular position.
  • EP 2 022 959 A2 is known from the prior art, for example, which shows a multi-joint crank drive in which the adjusting device for adjusting the rotational angle of the eccentric shaft comprises a lever arrangement via which a torque for setting the desired rotational angle position is applied to the eccentric shaft. Due to the large number of provided lever of the lever assembly, however, the adjusting device is maintenance-intensive. In addition, in the case of a regulated setting of the rotational angle position, oscillation around the desired rotational angle position can occur. Also, to hold the set angular position, the permanent supply of energy, also referred to as auxiliary power necessary.

  • the detent counter element is, for example, a detent disk, on the outer circumference of which there is at least one detent engagement as a depression.
  • the latching element can now be displaced in the radial direction with respect to the latching counter element and its central axis, so that it is spaced from the latching counter element or engages in the at least one latching engagement.
