Abstract:
A hybrid car including an internal combustion engine, a motor-generator, a clutch and a change gear, all of which are connected in the sequence to transmit a rotary driving force in the sequence, said hybrid car comprising:unidirectional rotation transmitting means provided between said internal combustion engine and said motor-generator, said unidirectional rotation transmitting means being adapted to transmit a rotary driving force generated by said internal combustion engine to said motor-generator and to block a transmission of a rotary driving force generated by said motor-generator to said internal combustion engine, wherein said unidirectional rotation transmitting means is a unidirectional clutch, and wherein said unidirectional clutch is disposed in a space defined in a rotor of said motor-generator and a stator of said motor-generator is disposed in an outer peripheral space of said rotor, said hybrid car further comprising a stator housing for housing said unidirectional clutch and said motor-generator, wherein said stator of said motor-generator is fixedly secured to an inside of said stator housing, and a flywheel housed in said stator housing and fixedly secured to said rotor of said motor-generator, a slit ring formed with a plurality of slits and fixedly secured to said flywheel and a rotation sensor provided inside said stator housing, for transmitting and receiving light passed through said slits of said slit ring.
