The invention provides a steering dust cover capable of preventing abnormal sound, which comprises a dust cover body provided with a steering transmission shaft via hole; the guide ring is fixed to the hole wall of the steering transmission shaft via hole of the dust cover body, a center hole in clearance fit with a steering transmission shaft is formed in the guide ring, and a plurality of oil storage grooves in the hole depth direction of the center hole are formed in the hole wall of the center hole in the circumferential direction; one end of the oil storage groove penetrates through the outer end face of the guide ring, and the other end of the oil storage groove is a blind end. The oil storage groove is formed in the hole wall of the center hole of the guide ring and used for storing the lubricating grease, so that it is guaranteed that the lubricating grease exists between the steering transmission shaft and the guide ring all the time, and steering abnormal sound caused by the fact that the lubricating grease is consumed up is avoided. In addition, the device is simple in structure, easy to machine and low in manufacturing cost.

    本发明提供了一种防异响的转向防尘罩,包括:防尘罩本体,所述防尘罩本体上开设有转向传动轴过孔;导向环,所述导向环固定在所述防尘罩本体的所述转向传动轴过孔的孔壁处,所述导向环开设有与转向传动轴间隙配合的中心孔,所述中心孔的孔壁在环周方向上设置有多个沿所述中心孔的孔深方向的储油槽,所述储油槽的一端贯通所述导向环的外端面,所述储油槽的另一端为盲端。本发明在导向环的中心孔的孔壁上设置储油槽用以储存润滑油脂,以此保证转向传动轴与导向环之间始终具有润滑油脂,避免因润滑油脂被消耗完而导致的转向异响。并且,本发明结构简单,易于加工,制造成本低。
