摘要： A suspension assembly (10) for attaching wheel assemblies (48) to a frame (12) includes a pair of torsion spring subassemblies (14, 16) adjustably interconnected by a center axle tube (18) to form a unitary axle-like assembly whose torsion spring subassemblies (14, 16) can be adjustably fixed in various desired spaced positions for connection to a selected frame (12) having a particular width. Each torsion spring subassembly (14, 16) includes a torque limiter and further includes a bracket member (20, 22), the bracket member (20, 22) being generally planar in shape and adapted to communicate forces from the wheel assemblies (48) directly through the torsion spring subassemblies (14, 16) to the frame (12) in a manner that minimizes deformation when the torque limiter engages. A method comprises providing a pair of torsion spring subassembies (14, 16), releasably adjustably interconnecting the torsion spring subassemblies (14, 16) with a center axle member (18) to form a unitary axle-like suspension assembly (10) having a particular width, and connecting the suspension assembly (10) to a frame (12) having a particular width.

摘要： A torsion spring cartridge (12) is provided for torsionally absorbing loads on a trailer frame. The cartridge (12) is insertable into an axle tube (12), is insertable into an axle tube (14) and includes a counter torque hub (26), a bearing block (28) spaced therefrom, and a torque shaft (18) mounted for oscillating rotational movement in the bearing block (28) with torsion rods (24) operably interconnected between the counter torque hub (26) and the torque shaft (18). The bearing block (28) and the torque shaft (18) each include over-rotation stops that cooperate to prevent over-rotation of the torque shaft (18). The bearing block (28) supports the inside of the axle tube (17) to prevent distortion of the axle tube (14) and transmits forces from the bearing block (28) and axle tube (14) directly to the trailer frame. The torsion rods (24) have ends with substantially circular cross sections, and are held in place by brazing.

摘要： On décrit une cartouche (12) de barre de torsion servant à absorber par torsion des charges sur un châssis de remorque. La cartouche (12) peut être introduite dans un tube support (14), et comprend un moyeu de contre-couple (26), un bloc palier (28) espacé du moyeu, ainsi qu'un arbre de torsion (18) monté de façon à effectuer un mouvement rotatif et oscillant dans le bloc palier (28), des tiges de torsion (24) étant réciproquement reliées de manière opérationnelle entre le moyeu de contre-couple (26) et l'arbre de torsion (18). Le bloc palier (28) et l'arbre de torsion (18) comprennent chacun des éléments de butée de sur-rotation qui coopèrent de façon à empêcher la sur-rotation de l'arbre de torsion (18). Le bloc palier (28) soutient l'intérieur du tube support (17) afin d'en empêcher la déformation, et il transmet des forces provenant du bloc palier (28) et du tube support (14) directement au châssis de remorque. Les tiges de torsion (24) comprennent des extrémités présentant des sections pratiquement circulaires, et sont maintenues en position par brasage.
