    • A twist beam type rear suspension having a pair of trailing arms (10R, 10L) disposed to extend along opposite sides of a vehicle as pivotably supported from a vehicle body at front ends and supporting at rear ends rear vehicle wheels to be rotatable about respective axes of rotation, a twist beam (26) connected between the pair of trailing arms and twistable about an axis of twisting, an assist link having a central portion disposed substantially transversely in the vehicle as supported from the vehicle body and opposite end portions movable relative to the vehicle body, and a pair of control links (50R, 50L) each having a first end (48R, 48L) pivotably connected with each trailing arms at its portion adjacent its front end and a second (52R, 52L) end pivotably connected with each end portion of the assist link (42), wherein the opposite end portions of the assist link are either movable in the longitudinal direction relative to the vehicle body in the same phase but unmovable in the longitudinal direction relative to the vehicle body in the phases opposite to one another and also unmovable in the transverse direction relative to the vehicle body or movable in the transverse direction relative to the vehicle body in the phases opposite to one another but unmovable in the transverse direction relative to the vehicle body in the same phase, a phantom straight line passing pivot centers of the pivoting connections at the first and second ends of each control link intersects one another at a point (62) positioned transversely central in the vehicle and longitudinally in a region extending rearward from a point substantially around the axes of rotation of the vehicle wheels as viewed from the top of the vehicle, and a phantom straight line passing a pivot center of the pivoting support of the front end of each trailing arm and one of the first and second ends of each control link traverses the axis of twisting.
    • 一种扭梁式后悬架,其具有一对拖臂(10R,10L),其设置成沿车辆的相对侧延伸,从车身的前端可枢转地支撑并且在后端支撑后车轮,以便绕各轴线旋转 连接在所述一对牵引臂之间并且可围绕扭转轴线扭转的扭梁(26),辅助连杆,其具有从所述车体支撑的所述车辆中基本上横向设置的中心部分,并且相对端部相对于 车身和一对控制连杆(50R,50L),每个控制连杆(50R,50L)具有第一端(48R,48L),其第一端(48R,48L)在与其前端相邻的部分处与每个拖臂枢转地连接;以及第二(52R,52L) 辅助连杆(42)的每个端部,其中辅助连杆的相对端部可以在相同相位中相对于车体的纵向方向移动,但在l中不可移动 相对于车身的相对方向的纵向方向,并且相对于车体在相对于车身的横向方向上不可移动,或者在相对于车体的相对于车身的横向方向上可移动,但在横向方向上不可移动 在相同相位相对于车体,通过枢转连接枢转中心的幻影直线在每个控制链节的第一和第二端处在位于车辆横向中心的点(62)处彼此相交,并在 从车辆顶部观察的基本上围绕车轮的旋转轴线的点向后延伸的区域,以及穿过每个拖臂的前端的枢转支撑件的枢转中心的幻影直线,以及 每个控制链接的第一和第二端横过扭转轴。
