    The invention relates to an internal combustion engine having an actuated by at least one Hubkolben- or Rotationskoiben drive shaft.
    The bearing of the drive shaft usually takes place via slide bearings or rolling bearings. This bearing with relatively high friction bearing the drive shaft requires a relatively large amount of space.
    It is known to carry out internal combustion engines coaxially with an electric machine in order to realize a hybrid drive for a vehicle.
    DE 35 23 344 A1 discloses a high-speed magnetically mounted rotor whose bearing forces are generated by the electric machine integrated with the rotor.
    The object of the invention is to allow as low-friction and space-saving storage of the drive shaft in an internal combustion engine of the type mentioned.
    According to the invention this is achieved in that the drive shaft is mounted on at least one electrodynamic bearing, wherein preferably the electrodynamic bearing is formed by an electric machine with a fixedly connected to the drive shaft rotor and a housing fixed stator.
    It when the electrodynamic bearing is arranged in the region of at least one main bearing wall, wherein preferably in the region of each main bearing wall, an electrodynamic bearing is provided is particularly advantageous.
    The rotor may be arranged in the region of at least one crank arm, with the crank arm being particularly preferably designed as a rotor.
    Characterized in that in the region of each main bearing wall, an electrodynamic bearing is provided, which is formed by an electric machine, 2 2 * * 4 * »* * * * * * t I · •« Γ; · · · Fr · ««
    • Space can be saved and a very low-friction operation of the internal combustion engine can be made possible.
    In addition, the electric machine can take over all hybrid functions. The electric machine can thus be used to support the internal combustion engine. In addition, a purely electric drive by the electric machine is possible. By means of the electric machine can also be carried out a very fast engine start. On the other hand, the electric machine can also be used as a power generator and recover braking energy in recuperative ferry operation.
    The invention will be explained in more detail below with reference to FIG.
    The Fig. Time schematically an internal combustion engine 1 with several reciprocating pistons 2, which act on a drive shaft 3. In the region of each Hauptiagerwand 4 a formed by an electric machine 5 electrodynamic bearing 6 is arranged. The rotor 7 of the electric machine 5 is formed by a crank arm 8 of the drive shaft 3. The housing-fixed Startor 9 is integrated into the main bearing wall 4.
    In the embodiment shown in the figure, the drive shaft 3 is supported between two adjacent reciprocating pistons 2 via a respective electrodynamic bearing 6. In addition, an electrodynamic bearing 6 is provided at each end 3a, 3b of the drive shaft 3 in each case. Thus, all sliding or rolling bearings of the drive shaft 3 are replaced by electrodynamic bearings 6. But it is also possible the drive shaft mixed, so support both electrodynamic bearing 6, as well as sliding and / or roller bearings on the housing 10 of the engine.
    By arranging the electrodynamic bearings 6 in the region of the main bearing walls 4, a very compact and low-friction bearing of the drive shaft 3 is made possible. The electric machines 5 can thereby "* 3" * 3 "♦ • *
    a ft take over all hybrid functions and thus support the internal combustion engine 1 in the fired operation, When switching off the internal combustion engine 1, a purely electrical operation is possible. Furthermore, the electric machines 5 can be used for quick starting of the internal combustion engine 1. In regenerative operation of the electric machines 5 braking energy of the vehicle can be recovered.
    The described arrangement enables a very compact drive unit for a hybrid vehicle, which can be dispensed with clutches between the electric machines 5 and the internal combustion engine 1.
