HYDRAULIC PUMP CONTROL MECHANISM FOR DRIVING ENGINE COOLING FAN OF HYBRID BUS

摘要

PROBLEM TO BE SOLVED: To provide a hydraulic pump control mechanism for driving an engine cooling fan of a hybrid bus.SOLUTION: A control mechanism of a hydraulic pump 10 for driving an engine cooling fan of a hybrid bus is configured so that: the hydraulic pump 10 for driving the engine cooling fan of the hybrid bus is driven by power provided by a transmission PTO 30 of the hybrid bus at idling; and the hydraulic pump 10 is driven by power supplied from a motor 20 of the bus at engine stop, and thereby operating the cooling fan for the engine of the hybrid bus at the engine stop and enabling management of an engine cooling water temperature.
