Hybrid transmission
First Claim
1. A hybrid transmission comprising:
- a housing having a common axis defined thereby, the housing being adapted to be positioned beside an engine when the hybrid transmission is mounted on a motor vehicle;
a differential speed change unit installed in the housing at a position near the engine and arranged coaxial with the common axis;
a two-rotor type motor/generator unit installed in the housing at a position away from the engine and arranged coaxial with the common axis, the motor/generator unit having inner and outer rotors and a wiring;
an inner rotor shaft connected with the inner rotor to rotate therewith, the inner rotor shaft being coaxial with the common axis and extending to the differential speed change unit to be operatively connected to the same; and
an outer rotor shaft connected with the outer rotor to rotate therewith, the outer rotor shaft being coaxial with the common axis and extending to the differential speed change unit to be operatively connected to the same;
wherein the housing has a split section at which the housing is dividable into two housing parts, the split section being positioned between the differential speed change unit and the motor/generator unit;
wherein the outer rotor shaft is concentrically received in the inner rotor shaft which is hollow, wherein the outer rotor is connected to the outer rotor shaft through a connecting member that is positioned at one axial end of the motor/generator unit that is opposite to the other axial end that faces the differential speed change unit, and wherein the wiring of the motor/generator unit is exposed to a space between the motor/generator unit and the differential speed change unit and led and exposed to the outside of the housing through an opening formed in the housing near the split section.

Abstract
A differential speed change unit is installed in a housing at a position near an engine and arranged coaxial with a common axis, and a two-rotor type motor/generator unit is installed in the housing at a position away from the engine and arranged coaxial with the common axis. The motor/generator unit has inner and outer rotors and a wiring. An inner rotor shaft is connected with the inner rotor to rotate therewith. The inner rotor shaft extends coaxially with the common axis to be operatively connected to the differential speed change unit. An outer rotor shaft is connected with the outer rotor to rotate therewith. The outer rotor shaft extends coaxially with the common axis to be operatively connected to the differential speed change unit. The housing has a split section at which the housing is dividable into two housing parts, and the split section is positioned between the differential speed change unit and the motor/generator unit.
