The invention relates to the technical field of engineering machinery, and provides a thrust wheel, a thrust wheel system and an operation machine.The thrust wheel comprises a lubricating oil channel, a lubricating oil inlet, a lubricating oil outlet and a one-way valve, the lubricating oil inlet is communicated with the lubricating oil channel and an oil outlet of an oil tank, and the lubricating oil outlet is communicated with the lubricating oil channel and an oil return opening of the oil tank; the lubricating oil channel is communicated with gaps among the wheel body of the thrust wheel, the wheel shaft, the first end cover, the second end cover and the floating oil seal; the lubricating oil inlet is formed in the first end cover or the wheel body, and the lubricating oil outlet is formed in the second end cover or the wheel body; when the pressure in the lubricating oil channel is larger than the first preset pressure of the one-way valve, the lubricating oil outlet is communicated with the lubricating oil channel. The lubricating oil inlet, the lubricating oil channel, the lubricating oil outlet and the oil tank form a circulating oil way, the internal pressure of the wheel body can be reduced through the one-way valve, the service life of the thrust wheel is prolonged, flowing of lubricating oil can be achieved, and the temperature in the thrust wheel is reduced.
本发明涉及工程机械技术领域,提供一种支重轮、支重轮系统及作业机械,支重轮包括润滑油道、分别与润滑油道和油箱出油口连通的润滑油进口、分别与润滑油道和油箱回油口连通的润滑油出口和单向阀,润滑油道设在支重轮的轮轴上,润滑油道与支重轮的轮体、轮轴、第一端盖、第二端盖和浮动油封间的间隙连通;润滑油进口设在第一端盖或轮体上,润滑油出口设在第二端盖或轮体上;单向阀设在轮轴上,润滑油道内的压力大于单向阀的第一预设压力时,润滑油出口与润滑油道连通。通过润滑油进口、润滑油道、润滑油出口与油箱形成循环油路及通过单向阀可降低轮体的内部压力,提高支重轮的使用寿命,可实现润滑油的流动,降低支重轮内部的温度。
