Abstract

A motor generator has a rotor directly coupled to a crankshaft and a stator disposed around the rotor. A shield plate is disposed between coils of the stator and an internal combustion engine. A first partition and a second partition are disposed between the coils and a flywheel positioned adjacent to a clutch mechanism.

Claims

1. A hybrid vehicle propulsion apparatus on a hybrid vehicle having a transmission and a drive axle coupled thereto, comprising:

an internal combustion engine for generating propulsive forces;

a motor generator for generating propulsive forces, said motor generator comprising a stator and a rotor;

a clutch mechanism comprising a friction clutch, said clutch mechanism and said motor generator being accommodated in a single housing, for selectively transmitting the propulsive forces from said internal combustion engine or said motor generator to the transmission; and

blocking means fixed to said rotor, for blocking an abrasive powder produced by said clutch mechanism against entry into said motor generator,

wherein said clutch mechanism is disposed between the blocking means and the transmission.

2. A hybrid vehicle propulsion apparatus according to claim 1, wherein said rotor has fins on a surface thereof which faces said blocking means.

3. A hybrid vehicle propulsion apparatus on a hybrid vehicle having a transmission and a drive axle coupled thereto, comprising:

an internal combustion engine for generating propulsive forces;

a motor generator for generating propulsive forces;

a clutch mechanism comprising a friction clutch, said clutch mechanism being disposed between said motor generator and said transmission, for selectively transmitting the propulsive forces from said internal combustion engine and said motor generator to the transmission; and

blocking means disposed between said motor generator and said clutch mechanism, for blocking an abrasive powder produced by said clutch mechanism against entry into said motor generator,

wherein said motor generator has a stator and a rotor, said blocking means comprising;

a first partition fixed to said stator;

a second partition fixed to said rotor;

said first partition and said second partition overlapping each other.

4. A hybrid vehicle propulsion apparatus according to claim 3, further comprising a flywheel coupled to said rotor, said second partition being fixed to said flywheel.
