| 20110266764 | SUSPENSION ASSEMBLY - A suspension system includes a frame mount assembly, a swing arm assembly and an air spring. The trailer includes a rail with top and bottom rail surfaces. The swing arm assembly is pivotally mounted to a pivot about a swing arm pivot axis located above the bottom rail surface when the suspension assembly is mounted to the trailer. | 11-03-2011 |
| 20100230923 | SUSPENSION ASSEMBLY - A vehicle suspension system includes a pair of suspension assemblies mounted on a pair of spaced vehicle frame members for supporting a vehicle body on the vehicle wheels. A torsion axle extends between the pair of suspension assemblies and terminates in a pair of stub shafts. The axle is mounted on a pair of spaced frame brackets attached to the vehicle frame. An air spring extends between the vehicle frame and an outer end of a support arm pivotally mounted on each end of the torsion axle. The stub shafts are supported within an outer tube of the torsion axle by a plurality of elastomeric members. One end of each stub shaft is connected to a spindle arm which has a spindle extending from an opposite end of the arm. The length of the air spring support arm and the distances between the pivot axis of the support arm and the axii of the spindle and torsion axle are chosen so that the surface of the air spring is always out of contact with the mounting bracket and has a portion inboard between the axis of the spindle and axis of the torsion axle. | 09-16-2010 |
| 20100207346 | SUSPENSION ASSEMBLY - A vehicle suspension system includes a frame mounting bracket. A torsion axle is pivotally attached to the frame mounting bracket. The torsion axle pivots about a suspension assembly pivot axis. An air spring support arm is rigidly attached to the torsion axle. An air spring is attached at one end to the frame mounting bracket and at an end of the support arm opposite the suspension assembly pivot axis. A spindle arm with a spindle is adapted for mounting a wheel assembly is attached to the torsion axle. The vehicle suspension system is adapted to include an optional cross-member brace adapted to attach to the frame mounting bracket allowing the cross-member brace to extend across a width of a vehicle to an adjacent vehicle suspension assembly. | 08-19-2010 |

| 20090278328 | SUSPENSION ASSEMBLY WITH COAXIAL TORSION BAR - A vehicle suspension system includes a pair of suspension assemblies mounted on a pair of spaced vehicle frame members for supporting a vehicle body on the vehicle wheels. A torsion axle extends between the pair of suspension assemblies and terminates in a pair of stub shafts. The axle is mounted on a pair of spaced frame bars attached to the vehicle frame. An air spring extends between the vehicle frame and an outer end of a support arm mounted on the torsion axle. The stub shafts are supported within an outer tube of the torsion axle by a plurality of elastomeric members. One end of each stub shaft is connected to a spindle arm which has a spindle extending from an opposite end of the arm. The outer tube of the torsion axle pivotally supports the air spring support arm and the axis of the torsion axle is coaxial with the pivot axis of the air spring support arm to provide a more compact and sturdy suspension assembly. | 11-12-2009 |
