Abstract:
A hybrid drive train for a self propelled power trowel includes a frame having a centerline from front to rear, an engine-generator set, a pair of rotors with trowel blades tiltably connected to the frame and positioned to support the frame above a concrete surface being finished, electric motors for driving the rotors, means for tilting each rotor toward and away from the centerline, and means for tilting a rotor fore and aft, parallel to the centerline. A rectifier and inverter in series at the engine-generator output allows engine speed to be regulated by a capacitor bank, and usage of highly efficient brushless AC synchronous motors to drive the rotors. A rechargeable battery may be connected in parallel with the capacitor bank.

Claim (Index 12):
A hybrid drive train for a self propelled power trowel, comprising:\n a rigid frame having a front and a rear and defining a centerline from front to rear; means for providing electrical power to said power trowel attached to the rigid frame; a pair of rotatable rotor assemblies tiltably connected to the rigid frame and configured to contact a concrete surface below the rigid frame and to support the rigid frame thereabove; one or more electrical motors electrically connected to the electrical power providing means and operatively connected to the rotatable rotor assemblies to cause rotation of said rotor assemblies; means for tilting each rotor assembly toward and away from the centerline of the frame; and means for tilting at least one of the rotor assemblies fore and aft, parallel to the centerline of the frame.
