Excavator and excavator power assembly and working gear matching method thereof
The invention relates to the technical field of engineering machinery, and discloses an excavator and an excavator power assembly and working gear matching method thereof, and the excavator comprises a main pump which is provided with a plurality of different working gears; the engine is used for providing mechanical energy for the main pump; the gearbox is provided with multiple different speed ratios, the multiple speed ratios correspond to the multiple working gears in a one-to-one mode, the gearbox is connected between the main pump and the engine in a transmission mode, and the excavator power assembly can be matched with the speed ratios corresponding to the gearbox according to the working gears of the main pump. And the rotating speed of the engine can be located in the economic rotating speed area of the engine at any working gear of the main pump. According to the excavator and the excavator power assembly and working gear matching method thereof, the economical efficiency is good, and the problem that the excavator is prone to shut down and flameout in the plateau environment can be effectively solved.
本申请涉及工程机械技术领域，公开了一种挖掘机及其挖掘机动力总成和工作档位匹配方法，该挖掘机及其挖掘机动力总成和工作档位匹配方法包括主泵，设有多个不同的工作档位；发动机，用于为主泵提供机械能；以及变速箱，设有多种不同的速比，多种速比与多个工作档位一一对应设置，变速箱传动连接在主泵和发动机之间，其中，所述挖掘机动力总成能够根据主泵的工作档位匹配所述变速箱对应的速比，使得发动机的转速在主泵的任一工作档位均能位于发动机的经济转速区。本申请的挖掘机及其挖掘机动力总成和工作档位匹配方法的经济性好，且能够有效改善在高原环境下挖掘机容易憋车熄火的问题。
