<P>PROBLEM TO BE SOLVED: To achieve energy saving, reduction of exhaust emission, and reduction of the noise by providing a hybrid driving source to restrain load change of an engine, and to perform steering and braking with oil pressure even when the engine stops to perform idling stop reduced in fuel cost, exhaust emission and noise by utilizing a power generator loaded as a hybrid driving device. <P>SOLUTION: This construction vehicle includes: a hydraulic work device A for performing work by driving hydraulic pumps 2, 6 by the engine 1 and driving an actuator by the discharged oil; a motor-driven running device B for driving the power generator 8 by the engine 1 to give and receive the power to and from a battery 12, thereby controlling the electric motor 9 by the power giving and receiving to and from the battery 12 to generate running driving force; a clutch 31 disposed between the engine 1 and a power distribution mechanism 30; and an idling stop control means 20 for disconnecting the clutch when the engine stops and driving the power generator by the power of the battery to be functioned as an electric motor, thereby driving the hydraulic pumps. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
