用于扭矩悬挂的角度调节系统和如此获得的扭矩悬挂
摘要：
在传统的挂接式拖车中，没有办法调节拖车的车身高度。本发明提供了一种用于包括轴(12)和曲柄臂(20)的悬架系统的角度调节结构(13)，所述轴(12)具有连接到所述曲柄臂(20)的连接端部(14)，所述角度调节机构(13)包括：设置在所述连接端部(14)上并从所述轴(20)向外指向的截头圆锥形表面(16)，所述截头圆锥形表面(16)具有沿圆周方向布置的第一空腔阵列(18)；邻近所述曲柄臂(20)的第一末端的截头圆锥形孔(22)，所述截头圆锥形孔(22)具有第二空腔阵列(24)，所述截头圆锥形孔(22)能够操作以与所述连接端部(14)的所述截头圆锥形表面(16)配合；和互锁元件(30)，所述互锁元件部分地定位在所述第二空腔(24)中的一个中和部分地定位在所述第一空腔(18)中的一个中，以相对于所述轴(12)将所述曲柄臂(20)锁定在预定角位置。此外，本发明提供了一种包括上述角度调节机构(13)的改进的扭转系统(10)。
摘要（英）：

In a traditional hitched trailer there is no way to adjust the ride height of the trailer. Provided is an angular adjusting mechanism (13) for a suspension system (10) comprising a shaft (12) and a crank arm (20), the shaft (12) having a connecting end (14) connected to the crank arm (20), said angular adjusting mechanism (13) comprising a frusto-comcal shaped surface (16) provided on the connecting end (14) and pointing outwardly from said shaft (12), said surface (16) having an array of first cavities (18) arranged circumferentially, a frusto-comcal bore (22) proximate a first extremity of said crank arm (20), said bore (22) having an array of second cavities (24), said bore (22) being operative to mate with said surface (16) of said connecting end (14), and an interlocking element (30) partly positioned in one of said second cavities (24) and partly positioned in one of said first cavities (18) so as to lock said crank arm (20) at a predetermined angular position with respect to said shaft (12). Also, an improved torsion suspension system (10) including the above mentioned angular adjusting mechanism (13) is provided.
