Abstract
A parallel hybrid drive for a motor vehicle includes a clutch integrated in an electric motor unit of the electrical machine of the parallel hybrid drive for allowing the electric motor unit to be disengaged from the drive train. Therefore, pure internal combustion engine drive is possible, without rotating the rotor of the electrical machine or the electric motor unit.
Claims20
A parallel hybrid drive for a motor vehicle, comprising:
- a drive train connecting an internal combustion engine to a transmission and connecting an electrical machine to said transmission, wherein said electrical machine comprises an external rotor arranged radially outside of a radially inner stator comprising a body section of said electrical machine;
- said drive train comprising a first clutch arraigned between said internal combustion engine and said transmission for selectively drivably connecting said internal combustion engsid to said transmission, said transmission being arranged between said first clutch and said electrical machine;
- and
- said drive train further comprising a second clutch integrated in said electrical machine and operatively arranged for selectively connecting said electrical machine to a remainder of said drive train, said second clutch beiss arranged in a cavity in said electrical machine bounded at least partially by said body section, said second clutch being coaxial with respect to said external rotor and wherein said external rotor radially surrounds at least a portion of a radial outside of said second clutch.
