    • A torsional bushing assembly for use in a vehicle, the assembly comprising: an elongated inner member having a main portion, a longitudinal axis and first and second ends, the main portion comprising a plurality of lobes extending generally radially outwardly with respect to said axis to give the main portion a generally cruciform cross-section; a bushing positioned on the main portion of the inner member, the bushing having a generally cylindrical outer periphery with protrusions and indentations formed thereon and generally cruciform shaped aperture defined therein in which the main portion of the tubular member is received; and a generally cylindrical housing in which the inner member and the bushing are disposed, the housing having protrusions extending generally radially inwardly with respect to said axis and corresponding to the indentations of the bushing; wherein the lobes and the protrusions are arranged to overlap in the radial direction so that, upon relative rotation of the inner member and the housing, portions of the bushing between the lobes and the protrusions are compressed.
    • 1。一种用于车辆的扭转衬套组件,所述组件包括:具有主要部分,纵向轴线以及第一和第二端部的细长内部构件,所述主要部分包括多个叶片,所述叶片相对于所述轴线大致径向向外延伸到 主要部分为大致十字形的横截面; 定位在内部构件的主要部分上的套管,套管具有大致圆柱形的外周边,该外周边上形成有突起和凹口,并且大体上限定有十字形的孔,管状构件的主要部分容纳在该孔中; 以及大致圆柱形的壳体,所述内部构件和所述衬套布置在所述壳体中,所述壳体具有相对于所述轴线大致径向向内延伸且对应于所述衬套的所述凹陷的突起; 其中所述凸起和所述凸起布置成在径向方向上重叠,使得在所述内侧构件和所述壳体相对旋转时,所述凸起和所述凸起之间的所述衬套的部分被压缩。
