    • A bushing assembly adapted for application in vehicle suspension systems includes an outer, generally cylindrical bushing member, an inner generally cylindrical bushing member arranged concentrically within the outer member. The two bushing members are interconnected by an elastomeric member disposed there between and bonded thereto to permit limited rotational displacement between the external and internal bushing members. An angular position sensor is at least partially embedded within the elastomeric member and operated to produce an output signal indicative of the relative angular position of the external and internal bushing members. The sensor includes a stator assembly including a permanent magnet, a galvanomagnetic sensing element and a flux guide defining at least one pole face, and a rotor including a flux guide defining a second pole face. An air gap between the two pole faces varies dimensionally as a function of the relative angular position of the stator assembly and rotor.
    • 适于应用于车辆悬架系统的衬套组件包括外部大致圆柱形衬套构件,同心地布置在外部构件内的大体上圆柱形的衬套构件。 两个衬套构件通过设置在其间并与其结合的弹性体构件互连,以允许外部和内部衬套构件之间的有限的旋转位移。 角度位置传感器至少部分地嵌入在弹性体构件内并且被操作以产生指示外部和内部衬套构件的相对角位置的输出信号。 传感器包括定子组件,该定子组件包括永磁体,电流磁感应元件和限定至少一个极面的磁通引导件,以及包括限定第二极面的磁通引导件的转子。 两个极面之间的气隙根据定子组件和转子的相对角位置的尺寸而变化。
