First Claim
1. A vehicle comprising:
- a frame;
a heat engine coupled to said frame;
a transmission including an input and an output;
an electrical device comprising a stator and a rotor, wherein said rotor comprises a rotor shaft having a first end and a second end, said transmission input coupled to said heat engine and said transmission output coupled to said electrical device such that substantially all of the torque generated by said heat engine is channeled through said transmission to said electrical device;
a differential;
a first drive shaft;
a first pair of universal joints that couple said first drive shaft to said rotor shaft first end and said transmission;
a second drive shaft;
a second pair of universal joints that couple said second drive shaft to said rotor shaft second end and said differential; and
a plurality of motor mounts that couple said electrical device to a sub-frame coupled to said vehicle frame, said plurality of motor mounts fabricated at least partially from a compliant material and configured to provide mechanical support for said electrical device to facilitate aligning said electrical device with said first drive shaft, said transmission, said second drive shaft, and said differential.

Abstract
A parallel hybrid vehicle includes a heat engine, a transmission including an input and an output, and an electrical device. The transmission input is coupled to the engine and the transmission output is coupled to the electrical device such that substantially all of the torque generated by the heat engine is channeled through the transmission to the electrical device, and a differential, the electrical device coupled to the differential such that during a first mode of operation the electrical device functions as a motor to receive substantially all the torque generated by the engine through the transmission, and such that during a second mode of operation the electrical device functions as a generator to receive substantially all the torque generated by the vehicle through the differential. A method of retrofitting a vehicle is also provided.

14. A method of retrofitting a vehicle that includes a vehicle frame, a heat engine, a transmission coupled to the engine, a differential, and at least one drive shaft coupled between the transmission and the differential, said method comprising:
-
removing the at least one drive shaft; coupling an electrical device between the transmission and the differential such that during a first mode of operation the electrical device functions as a motor to receive substantially all the torque generated by the engine through the transmission, and such that during a second mode of operation the electrical device functions as a generator to receive substantially all the torque generated by the differential, the electrical device including a stator and a rotor, wherein the rotor includes a rotor shaft having a first end and a second end; coupling a first drive shaft to the rotor shaft first end and to the transmission using a first pair of universal joints; coupling a second drive shaft to the rotor shaft second end and to the differential using a second pair of universal joints; and coupling a plurality of motor mounts to a sub-frame coupled to the vehicle frame, the plurality of motor mounts fabricated at least partially from a compliant material and configured to provide mechanical support for the electrical device to facilitate aligning the electrical device with the first drive shaft, the transmission, the second drive shaft, and the differential. - View Dependent Claims (15, 16, 17, 18)
