一、我国汽车轮毂轴承润滑的基本情况目前,我国各地汽车轮毂轴承的润滑方式大致可分为三种:①沿用落后的满毂润滑(图1),轮毂轴承和空腔里都装满润滑脂;②采用空毂润滑技术(图2),只轴承裝满润滑脂,轮毂空腔内不装润滑脂或只涂很薄一层润滑脂防锈;③认为满毂润滑不合理或不必要,但又顾虑空毂润滑不可靠,于是采取折衷办法,在轮毂空腔里涂占其容积三
First, the basic situation of automotive wheel bearings in China At present, the wheel bearings around our country can be roughly divided into three types of lubrication: ① behind the use of full hub lubrication (Figure 1), the hub bearing and cavity are filled with grease ; ② The use of empty hub lubrication technology (Figure 2), only the bearing filled with grease, the wheel cavity is not filled with grease or grease coating a very thin layer of grease; ③ that the full hub lubrication unreasonable or unnecessary, However, considering the empty hub lubrication is not reliable, so take a compromise approach, in the hub cavity painted its volume three
