A seal assembly for a truck hub assembly includes an inner annular shell having an axial portion deployable about a shaft and a radial portion extending radially outward from the axial portion. An outer annular shell is coupleable with the bore of the hub and has a radial portion extending radially inward from the bore. An annular elastomeric sealing member has a base portion disposed on the outer shell and at least one flexible axial sealing lip having a first end integrally formed with the base portion and a second free end sealingly engageable with the radial portion of the inner shell. A radial protrusion extends radially inward from the radial portion of the outer shell and has an inner radial end positioned adjacent to the axial portion of the inner shell or an outer peripheral surface disposed about the shaft and spaced radially outward from the axial portion of the inner shell or the outer peripheral surface disposed about the shaft, thus, a labyrinth seal gap is formed.

    一种用于卡车轮毂组件的密封组件包括内环形壳,所述内环形壳具有能够绕着轴布置的轴向部分和从轴向部分在径向上向外延伸的径向部分。外环形壳能够与毂的孔联接并且具有从所述孔在径向上向内延伸的径向部分。环形弹性体密封构件具有布置在外壳上的基部部分和具有第一端部和第二自由端部的至少一个柔性的轴向密封唇,所述第一端部与基部部分一体形成,所述第二自由端部能够与内壳的径向部分密封地接合。径向突起从外壳的径向部分在径向上向内延伸并且具有内径向端部,所述内径向端部定位为邻近于内壳的轴向部分或绕着轴布置的外周表面,并且与内壳的轴向部分或绕着轴布置的外周表面在径向上向外间隔开,使得形成迷宫密封间隙。
