The invention discloses an electric drive engineering machinery hydraulic oil way system which comprises a hydraulic system and an oil cooling motor, and the hydraulic system and the oil cooling motor are circularly connected through an oil supply pipeline. The hydraulic system and the oil cooling motor share the same oil supply system which is recycled, so that a set of related oil way assemblies can be saved, the installation space of the engineering machinery vehicle is saved, and the stability of the hydraulic oil way system is correspondingly improved due to the fact that parts are reduced. Compared with a water-cooled motor structure, the motor power density is greatly improved by adopting the oil-cooled motor, the size of the oil-cooled motor is smaller than that of the water-cooled motor, the installation space can be saved, and the cooling efficiency and the cooling effect are greatly improved through the oil-cooled mode; compared with an independently-arranged oil cooling motor mechanism, the oil cooling motor and an oil supply component of a hydraulic system can be shared, so that the system structure is simplified, the stability is improved, and meanwhile the cost is correspondingly reduced.
本发明公开了一种电驱动工程机械液压油路系统,包括液压系统和油冷电机,所述液压系统和所述油冷电机通过供油管路循环连接。本发明通过将液压系统和油冷电机共用同一套循环使用的供油系统,从而可节省一套相关油路组件,不但节约工程机械车辆的安装空间,而且由于部件减少,使得液压油路系统的稳定性也相应提高。相对于水冷电机结构,本发明采用油冷电机大大提高了电机功率密度,而且油冷电机相比于水冷电机体积更小,可以节省安装空间,而且油冷方式使得冷却效率和冷却效果大大提高;相对于独立设置的油冷电机机构,本发明可将油冷电机和液压系统的供油部件共用,从而简化系统结构、提高稳定性,同时也相应降低成本。
