Hybrid Working Vehicle
First Claim
1. A hybrid working vehicle, comprising:
- an engine;
a drive wheel;
a power take-off (PTO) shaft;
a power transmission system for transmitting power from the engine to the drive wheel and the PTO shaft, the power transmission system being bifurcated at a bifurcating point into a traveling drive train for driving the drive wheel and a PTO drive train for driving the PTO shaft;
a continuously variable transmission provided on the traveling drive train;
a motor generator provided on the power transmission system between the engine and the bifurcating point,wherein the motor generator functions as a generator driven by the engine to charge electric power in a battery or functions as an electric motor supplied with electric power from the battery to drive the power transmission system; and
a controller for controlling an output rotary speed of the motor generator functioning as the electric motor.

Abstract
A hybrid working vehicle comprises an engine, a drive wheel, a power take-off (PTO) shaft, and a power transmission system for transmitting power from the engine to the drive wheel and the PTO shaft. The power transmission system is bifurcated at a bifurcating point into a traveling drive train for driving the drive wheel and a PTO drive train for driving the PTO shaft. A continuously variable transmission is provided on the traveling drive train, and a motor generator is provided on the power transmission system between the engine and the bifurcating point. The motor generator functions as a generator by power of the engine and functions as an electric motor for driving the power transmission system. The hybrid working vehicle includes a controller for controlling an output rotary speed of the motor generator functioning as the electric motor.
