Abstract
Abstract A multipowered source vehicle having two or more power sources which can be operated concurrently or asynchronously and which include an electric motor and an engine. The electric motor and engine are each connected to one output shaft and arranged in parallel with each other and transverse of the longitudinal axes of the vehicle. In concurrent operation, the electric motor and engine operate to enhance the total power of the vehicle.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
107 words
A multiple power source vehicle comprised of: at least two power sources; at least two output shafts, one each of said output shafts being connected to one each of said power sources; at least one belt-driven continuously variable torque converter; and at least one solenoid clutch means, said belt-driven continuously variable torque converter being disposed between said two output shafts and said clutch means being disposed adjacent said belt-driven continuously variable torque converter for shifting power transmission between the output shaft of one of said power sources and the output shaft of the second of said power sources, said output shafts being connected parallel of one another.
Claim 2
Dependent Claim
