Abstract: A suspension assembly and method of use is provided. The suspension is for an axle on a trailer or other vehicle. The suspension assembly has a cross support member connected with or integrally formed with a hanger bracket at the first end of the cross support member. A trailing beam is connected to the hanger bracket. The trailing beam and a mount are coupled with a load air bag and a lift air bag, with the bags located on each respective side of a pivot axis for the trailing beam. This establishes a teeter-totter configuration of the suspension assembly allowing independent wheel travel side-to-side of the suspension assembly.

Abstract: A suspension system for a vehicle includes a frame mounting bracket for mounting to the vehicle. First and second levers are pivotally mounted to the frame mounting bracket. First and second rubber torsion axle assemblies are rigidly mounted to the first and second levers, respectively. A control arm pivotally connects to the first lever and the second lever. The control arm, and the first and second levers are configured to rotate the first rubber torsion axle assembly and the second rubber torsion axle assembly simultaneously when a static or dynamic force is encountered by the suspension assembly. First and second spindle swing arms can be attached to the first and second torsion axle assemblies respectively with the first spindle swing arm extending forward of the first lever with respect to a direction the vehicle normal travels and the second swing arm can trail the second lever in a “push-pull” configuration.

Abstract: A suspension system for a vehicle includes a frame mounting bracket for mounting to the vehicle. The suspension includes front and rear rubber torsion axle assemblies. Front and rear lever assemblies are respectively pivotally attached to the vehicle at front and rear lever pivot points. Outer housings of the rubber torsion axle assemblies are each respectively rigidly mounted to the front and rear lever assemblies. A rigid control arm is pivotally connected at one end to the front lever assembly at a front control arm pivot point and its other end is pivotally connected to the rear lever assembly at a rear control arm pivot point. When the suspension assembly encounters a force causing the front lever assembly to rotate in one direction about the front lever pivot point the rigid control arm causes the rear lever assembly to rotate about the rear lever pivot in an opposite direction.

Abstract: A suspension assembly for a vehicle including an elongated central torsion axle shaft of a rubber torsion axle assembly, a torsion axle shaft pivot point about which the torsion axle shaft pivots, a spring and an elongated spindle swing arm. The spring has a first end and a second end and the first end of the spring is connected to a fixed point relative to a vehicle frame. The spindle swing arm has a second end with the first end connected to the torsion axle shaft with the second end of the spindle swing arm connected to the second end of the spring. The spring can set the torsion axle shaft to a predetermined position, such as at or near a no-load position, when only static forces are present. This provides for a torsion axle with a greater range of movement and significantly improves its lifespan.

Abstract: A suspension system for use with a vehicle including an axle tube, an internal tube and a locking structure. The axle tube is adapted to be attached to the vehicle. The internal tube assembly has an inner member with a first end and a second end. A locking structure is formed integrally at the second end with the inner member. The locking structure has a locking shape that allows the internal tube assembly to be inserted into the axle tube when the locking structure is rotated to a non-operational position. The internal tube assembly is prevented from being removed from the axle tube when the internal tube assembly rotates between jounce and rebound positions when the suspension system is operational.

Abstract: A shifter (10) comprises control electronics (20) which eliminate mechanical switches, providing increased reliability. The shift mechanics include a double-spring (28,30) disposed between a spring guide (32). The springs are compressed responsive to a driving screw (36) under control of a bidirectional motor (12). The motor (12) is controlled by the control electronics (20).
