The invention relates to a steering dust cover structure for solving the problem of abnormal sound of a steering dust cover. The steering dust cover structure comprises the dust cover, a plastic ringupper cover, a plastic ring lower cover, a plastic ring and a middle transmission shaft; the periphery of the middle transmission shaft is sleeved with the plastic ring, and the plastic ring is in interference fit with the middle transmission shaft; one end of the plastic ring is connected with the plastic ring upper cover, and the other end is connected with the plastic ring lower cover; the plastic ring upper cover and the plastic ring lower cover are in butt joint to form a cavity, the plastic ring is assembled in the cavity, and the plastic ring is in clearance fit with the cavity; and a grease block is also coated in the cavity. The steering dust cover structure for solving the problem of abnormal sound of the steering dust cover has the following advantages: the plastic ring and themiddle transmission shaft are in interference fit, when the middle transmission shaft rotates, the plastic ring is driven to rotate, due to the fact that the plastic ring is in clearance fit with theplastic ring lower cover and the plastic ring upper cover, the middle is filled with grease, the lubricating effect is achieved, and the grease is not prone to volatilization, so noise generated by friction is effectively reduced.

    本发明涉及一种解决转向防尘罩异响的转向防尘罩结构,所述的转向防尘罩结构包括防尘罩、塑料环上盖、塑料环下盖、塑料环、中间传动轴;所述的中间传动轴的外周套接塑料环,且塑料环与中间传动轴之间呈过盈配合;所述的塑料环一端连接塑料环上盖,另一端连接塑料环下盖;所述的塑料环上盖与塑料环下盖对接形成空腔,该空腔装配塑料环,且塑料环与该空腔之间的配合为间隙配合;所述的空腔内还涂有油脂块。其优点表现在:本发明的一种解决转向防尘罩异响的转向防尘罩结构,塑料环与中间传动轴之间呈过盈配合,当中间传动轴转动时,带动塑料环转动,由于塑料环与塑料环下盖和塑料环上盖为间隙配合,中间填满油脂,启润滑作用且油脂不易挥化,有效的降低摩擦产生的噪音。
