    • A sealing arrangement includes a radial shaft seal and a sensor ring for inductively detecting angular motion relative to a sensor. The radial shaft seal has at least one dynamically stressed sealing lip of an elastomeric material that is affixed to a radially extending limb of an essentially L-shaped reinforcement ring. An axially extending limb of the reinforcement ring is joined to a statically stressed seal. The axial limb is surrounded at least radially on the outside by an extrusion coating of elastomeric material, the sensor ring having an axial projection that extends radially on the inner side and at least partially surrounding the extrusion coating with radial prestressing. The radial shaft seal and the sensor ring form one unit that is capable of being preassembled, so as to allow them to be separated from one another, as needed, without being damaged.
    • 密封装置包括径向轴密封件和用于感应地检测相对于传感器的角运动的传感器环。 径向轴密封件具有弹性体材料的至少一个动态应力密封唇缘,其被固定到基本上L形的加强环的径向延伸的肢体上。 加强环的轴向延伸的肢体连接到静态应力密封件。 通过弹性体材料的挤压涂层,轴向肢体在外部至少径向包围,传感器环具有径向在内侧延伸并至少部分围绕挤压涂层的径向预应力的轴向突起。 径向轴密封和传感器环形成一个能够被预组装的单元,以便根据需要使它们彼此分离,而不被损坏。
