The invention discloses a tractor hydraulic power output system which comprises a hydraulic oil pump. The hydraulic motor is connected with the hydraulic oil pump; the speed reduction differential mechanism is connected with the hydraulic motor; the hydraulic oil pump is connected with a rear output shaft of the tractor through a first universal joint; and an output shaft of the speed reduction differential mechanism is connected with a driving shaft of the crawler walking mechanism. The output shaft of the tractor is used as a power input source, when power output supply is needed (when the tractor runs under poor road conditions), a driver starts the main controller, the main controller controls the hydraulic pump and the hydraulic motor to start to work, auxiliary power is provided for the tractor, and when power output supply is not needed, the main controller controls the hydraulic pump and the hydraulic motor to start to work. Due to the fact that the hydraulic motor is a plunger motor with the zero-displacement function, the hydraulic motor is in a zero-displacement lubricating state, power is not provided, and meanwhile synchronism of the tractor and the trailer can be achieved.

    本发明公开了一种拖拉机液压动力输出系统,包括液压油泵;与所述液压油泵连接的液压马达;与所述液压马达连接的减速差速器;所述液压油泵通过第一万向节连接拖拉机的后输出轴;所述减速差速器的输出轴连接履带行走机构的驱动轴。本发明使用拖拉机输出轴作为动力输入源,当需要动力输出供给时(即路况不太好行驶时),驾驶员启动所述主控制器,所述主控制器控制所述液压泵和所述液压马达开始工作,给予拖拉机辅助动力,当不需要供时,由于所述液压马达为具有零排量功能的柱塞马达,使所述液压马达于零排量的润滑状态,不提供动力,同时还可以实现拖拉机和挂车的同步性。
