Thermal management system for bulldozer and bulldozer
According to the heat management system for the bulldozer and the bulldozer, two two-position two-way hydraulic pilot valves of a reversing valve set are connected in series to form a series branch, and the two ends of the series branch communicate with the output end of a flow adjusting assembly and an oil supply tank correspondingly; the first input end of the two-position four-way electromagnetic valve is communicated with the output end of the flow adjusting assembly, the second input end of the two-position four-way electromagnetic valve is communicated with the second input end of the two-position four-way electromagnetic valve of the other reversing valve group, and the two output ends of the two-position four-way electromagnetic valve are respectively communicated with the first pressure ends of the two two-position two-way hydraulic pilot valves; the second pressure ends of the two two-position two-way hydraulic pilot valves are communicated with the series branch; the two ends of the reversing oil way are respectively communicated with the reversing oil port and a pipeline between the two two-position two-way hydraulic pilot valves; an output shaft of the hydraulic motor is in transmission connection with a central rotating shaft of the temperature control fan. The temperature control fan can be driven to rotate forwards or reversely or stop rotating, the rotating speed of the temperature control fan can be adjusted, and energy waste can be avoided.
本发明公开了推土机用热管理系统及推土机，该推土机用热管理系统，换向阀组的两个两位两通液压先导阀串联形成串联支路，串联支路的两端分别与流量调节组件的输出端和供油油箱连通；两位四通电磁阀的第一输入端与流量调节组件的输出端连通，第二输入端与另一换向阀组的两位四通电磁阀的第二输入端连通，两个输出端分别与两个两位两通液压先导阀的第一压力端连通，两个两位两通液压先导阀的第二压力端均与串联支路连通；换向油路的两端分别与换向油口和两个两位两通液压先导阀之间的管路连通；液压马达的输出轴与温控风扇的中心转轴传动连接。能够带动温控风扇正转、反转或停止旋转，能够调整温控风扇的转速，且能避免造成能量浪费。
