The invention relates to the field of an automobile and particularly relates to a protective cover of a steering device. The protective cover comprises a cover body, an oil bin, a circulating pump, apressure regulating device and a pressure switch, wherein the circulating pump is communicated with the oil bin, an inner cavity used for containing a rack is formed in the middle of the cover body, an oil channel is formed in the cover body, two ends of the oil channel extend out of the cover body, one end of the oil channel is communicated with a circulating pump through a pipeline, the other end of the oil channel is communicated with an oil bin, and the pressure regulating device is connected with the oil duct and is used for regulating the pressure in the oil duct. The protective cover isadvantaged in that the lubricating oil can be added into a rack in the inner cavity at any time, and meshing stability between the gear and the rack can be kept; a pressure switch is controlled to beopened and closed through oil pressure in the oil duct very conveniently, when part of lubricating oil flows out of the through hole, the oil pressure reduction pressure switch is automatically closed, and the excessive lubricating oil cannot be discharged at a time.
本发明涉及汽车领域,具体涉及一种转向装置的保护罩,包括罩体、油仓、循环泵、调压装置和压力开关;所述循环泵与油仓连通;所述罩体中部开设有用于放置齿条的内腔,所述罩体内开设有油道,所述油道的两端延伸至罩体外部,其中一端通过管道与循环泵连通,另一端与油仓连通;所述调压装置与油道连接,所述调压装置用于调节油道内部的压力;本发明的有益效果在于:能够随时向内腔内的齿条添加润滑油,能够保持齿轮齿条之间啮合稳定;通过油道内油压来控制压力开关开闭,十分便捷;当部分润滑油流出通孔后,油压降低压力开关自动关闭,不会造成一次排出过多的润滑油。
