Walking type engineering machinery hydraulic system and hydrostatic bulldozer
The invention discloses a walking type engineering machinery hydraulic system. The walking type engineering machinery hydraulic system comprises a chassis hydraulic system and a working device hydraulic system, wherein the chassis hydraulic system comprises a first walking variable pump, a second walking variable pump, a first variable motor connected with the first walking variable pump to form afirst circulating oil way, a second variable motor connected with the second walking variable pump to form a second circulating oil way, an electro-hydraulic system, an oil supplementing pump and a walking oil tank connected with the oil supplementing pump; the oil supplementing pump is connected with the first circulating oil way and the second circulating oil way respectively, and the electro-hydraulic system is connected with a first walking variable pump control unit, a second walking variable pump control unit, a first variable motor control unit and a second variable motor control unitrespectively so as to control the whole machine to walk. The working device hydraulic system comprises a working oil tank, a working pump and a hydraulic transmission system which are sequentially connected. According to the walking type engineering machinery hydraulic system, the chassis hydraulic system and the working device hydraulic system operate independently, so that pollution sources do not move mutually, and faults in use are reduced.
本发明公开一种行走式工程机械液压系统，包括底盘液压系统和工作装置液压系统，底盘液压系统包括第一行走变量泵、第二行走变量泵、与第一行走变量泵连接形成第一循环油路的第一变量马达、与第二行走变量泵连接形成第二循环油路的第二变量马达、电液系统、补油泵和与补油泵连接的行走油箱，补油泵与第一循环油路和第二循环油路分别连接，电液系统与第一行走变量泵控制单元、第二行走变量泵控制单元、第一变量马达控制单元和第二变量马达控制单元分别连接，以控制整机行走；工作装置液压系统包括依次连接工作油箱、工作泵和液压传动系统。本发明使底盘液压系统和工作装置液压系统独立运行，使污染源不互窜，降低使用故障。
