The invention relates to a tractor steering oil return lubrication hydraulic system and a tractor with the same, the tractor steering oil return lubrication hydraulic system comprises a gearbox, a steering gear, a hydraulic oil radiator and a lubrication heat dissipation end, a hydraulic oil outlet of the gearbox is connected with a hydraulic oil inlet of the steering gear through an inlet pipeline, and a pump body is arranged on the inlet pipeline; a hydraulic oil outlet of the steering gear is connected with an inlet of the hydraulic oil radiator through a pipeline, an outlet of the hydraulic oil radiator is connected with an oil return pipeline through a pipeline, one end of the oil return pipeline is connected with a plurality of lubricating branch pipelines in parallel, and each lubricating branch pipeline corresponds to one heating point position and is used for spraying and lubricating the heating point position. The other end of the oil return pipeline is connected with an oil return opening of the gearbox and provided with a lubricating back pressure valve. The forced lubrication heat dissipation device has the advantages that the lubrication heat dissipation hydraulic oil with certain pressure is generated through the lubrication back pressure valve, and meanwhile, the pressure of the lubrication heat dissipation hydraulic oil is adjusted by setting the opening pressure of the lubrication back pressure valve, so that the purpose of forced lubrication heat dissipation is achieved.

    本发明涉及拖拉机转向回油润滑液压系统及具有其的拖拉机,拖拉机转向回油润滑液压系统包括变速箱、转向器、液压油散热器和润滑散热端,变速箱的液压油出口通过进口管线连接转向器的液压油入口,且该进口管线上设有泵体,转向器的液压油出口通过管线连接液压油散热器的进口,液压油散热器的出口通过管线连接回油管线,回油管线的一端并联多个润滑支管线,每个润滑支管线均对应一个发热点位,并用于对发热点位喷洒润滑,回油管线的另一端连接变速箱的回油口,回油管线另一端设有润滑背压阀。优点:通过润滑背压阀产生具有一定压力的润滑散热液压油,同时,通过设置润滑背压阀的开启压力,调节润滑散热液压油的压力,从而达到强制润滑散热的目的。
