    Abstract: A system for enabling modification and adjustment of an automobile torsion bar suspension assembly housed in a tubular beam housing includes a plurality of torsion spring stiffener members, each comprising a tubular member dimensioned to be slidably received about the torsion leaf spring assembly within the beam housing. The tubular member includes opposed end portions provided with an inner peripheral surface formed complementary to the outer surface conformation of the leaves of the torsion bar assembly and adapted to engage the leaves assembly in nonrotating fashion. The stiffener member acts to rotationally immobilize a segment of the length of the torsion leaf assembly, thereby increasing the stiffness of the torsion spring. The invention also includes a socket tool having a recess in one end formed in complementary fashion to the outer surface conformation of the torsion leaf assembly and adapted to be engaged thereon. The other end of the socket tool is provided with a receptacle adapted to receive a standard drive lug of a torque wrench. A partial circumferential slot is provided in the beam housing adjacent to the internal block, and a pair of toothed locking plates are welded to the beam housing adjacent to the slot. A mounting screw secured to the internal block extends through the slot, and a top plate is secured to the screw. The top plate includes complementary teeth to enable rigid mounting of the internal block and torsion leaf assembly at variable angles with respect to the beam housing, thus selectively setting the height of the auto suspension.

    Abstract translation: 一种用于实现容纳在管状梁壳体中的汽车扭力杆悬挂组件的修改和调整的系统包括多个扭转弹簧加强件，每个扭转弹簧加强件均包括一个管状构件，该管状构件的尺寸设计成围绕梁壳体内的扭转弹簧组件可滑动地容纳。 管状构件包括相对的端部，其具有形成为与扭杆组件的叶片的外表面构造互补的内周表面，并且适于以非旋转方式接合叶片组件。 加强件用于旋转地固定扭转叶片组件长度的一段，从而增加扭转弹簧的刚度。 本发明还包括一个插座工具，其一端具有与扭转叶片组件的外表面构造互补的方式形成并适于与其接合的凹入部。 插座工具的另一端设置有适于容纳扭矩扳手的标准驱动凸耳的插座。 在梁壳体内邻近内部块设置部分圆周槽，并且一对有齿的锁定板被焊接到与槽相邻的梁壳体上。 固定到内部块的安装螺钉延伸穿过槽，顶板固定在螺钉上。 顶板包括互补的齿，以使得内部块和扭转叶片组件能够相对于梁壳体以可变的角度进行刚性安装，从而选择性地设定自动悬架的高度。
