Abstract:
PROBLEM TO BE SOLVED: To provide a starter of a new hybrid type construction machine capable of preventing a power relay from being degraded or damaged accompanying the power relay disconnection (forced block) at the engine starting.SOLUTION: An electric motor 23 is driven after the voltage of a shared battery 44 that supplies electric power to a starter motor 41, a power relay 54, and control means 80 becomes equal to or higher than the voltage necessary for these actions. Thereby, it is possible to prevent a power relay 54 from being opened (forced blocked) during the assist drive by the electric motor 23, so that it is possible to prevent the degradation, damage of the power relay 54 due to the opening of the power relay 54.SELECTED DRAWING: Figure 5
