专利内容由知识产权出版社提供专利名称：HYDRAULIC HYBRID SWING DRIVE SYSTEMFOR EXCAVATORS发明人：CULLMAN, Jeff,ZHANG, Hao,KIMPEL, RichardD.,JIANG, Zhesheng,COLLETT,Raymond,KOZUL, Bogdan申请号：EP13701135.9申请日：20130104公开号：EP2800837A2公开日：20141112摘要：A swing drive system (11) for an excavator is provided which utilizes a primemover (20) mechanically connected to a first hydraulic pump/motor (30) and a secondhydraulic pump/motor (32) mechanically connected to a swing mechanism (70). Thesystem includes a hydraulic circuit (31) connecting a hydraulic fluid reservoir (42), ahydraulic accumulator (40), the first hydraulic pump/motor (30), and the second hydraulicpump/motor (32). The system is operable in one mode where the second hydraulicpump/motor acts as a pump to retard movement of the swing mechanism andpressurized hydraulic fluid from the second hydraulic pump/motor is pumped into thehydraulic accumulator. The system is operable in another mode where the pressurizedfluid from the hydraulic accumulator is used to assist the prime mover in driving hydraulicconsumers (62,64,66), including the swing mechanism.申请人：Parker Hannifin Corp.,Cullman, Jeff,Zhang, Hao,Kimpel, Richard D.,Jiang,Zhesheng,Collett, Raymond,Kozul, Bogdan地址：6035 Parkland Blvd. Cleveland, OH 44124-4141 US,450 Whitestone CircleWadsworth, Ohio 44281 US,2632 Myrick Lane Twinsburg, Ohio 44087 US,19250 Fowles burg Hts.
