A vehicle drive apparatus includes a fluid coupling connected to an engine, and a rotating electric machine connected to the engine via the fluid coupling. The fluid coupling has an impeller to which torque having been output from the engine is input, and a turbine facing the impeller. The impeller rotates about a rotation axis. Torque having been output from the impeller is input to the turbine via a fluid. The turbine rotates about the rotation axis. The vehicle drive apparatus has a path provided between an output shaft of the engine and the impeller, the path through which torque having been output from the engine is transmitted to the impeller not via the turbine, and paths through which torque having been input to the impeller is output via the rotating electric machine, passing through a radially outside relative to the impeller with respect to the rotation axis from the impeller via the turbine.

Vehicle drive apparatus

A rotary electrical machine includes a stator, a field core, a rotor, and first and second air gaps. The stator includes an AC coil that generates a rotating magnetic field with an alternating current. The field core includes a field coil excited by a direct current. The rotor is disposed on an outer circumference of a starting apparatus and held rotatably about a rotational axis relative to the stator and the field coil. The first air gap is formed between the stator and the rotor, and allows a magnetic flux to flow therebetween. The second air gap is formed between the field core and the rotor, and allows a magnetic flux to flow therebetween. The second air gap defines an interval extending along a direction that intersects an axial direction of the rotational axis on one end surface of the rotor in the axial direction of the rotational axis.

Rotary electric machine

A hybrid driving apparatus includes a forward-reverse switching mechanism, a transmission, an input path disposed on an output side of the forward-reverse switching mechanism, and a motor connected to the input path.

Hybrid driving apparatus

A power transmission apparatus for vehicle, incorporated in a vehicle equipped with a transmission, includes a forward-reverse switching mechanism with start function produced by adding a function of a vehicle start clutch to the forward-reverse switching mechanism. Additionally, a power transmission system for vehicle includes an internal combustion engine that is a power source for vehicle driving, the transmission, a torsional vibration damper that transmits torque of the internal combustion engine to the transmission, and the forward-reverse switching mechanism with start function of the power transmission apparatus for vehicle. The forward-reverse switching mechanism with start function is disposed between the transmission, and the internal combustion engine and the torsional vibration damper.

Power transmission apparatus for vehicle and power transmission system for vehicle

A power transmission apparatus, which is disposed on a power transmission path from an output shaft of an internal combustion engine to a transmission in a vehicle, is provided with a rotating electrical machine including a rotor and a stator. The rotor is coupled to a synchronous rotating member that rotates synchronously with the output shaft of the internal combustion engine, and takes a central axis of the output shaft of the internal combustion engine as a rotating shaft. The stator is fixed to a fixing member on a non-rotating side with respect to the synchronous rotating member, and faces the rotor with a first gap therebetween.
