摘要： An axle-to-beam connection for a vehicle having a beam type suspension system is disclosed. The beam-to-axle connection includes an axle connection, a beam connection and a resilient member located therebetween. The resilient member forms a continuous path between the axle connection and the beam connection such that the axle connection and the beam connection do not directly interface at any point. The axle connection includes a saddle plate, which retains the axle, and a pair of extension plates which are connectable to the saddle plate and extend down along both sides of the beam. The resilient member is of a non-uniform shape and thickness and includes a continuum of loci which is designed and shaped so that each locus assumes its fair share, but not more, of the torsional, vertical and horizontal forces exerted on the resilient member during operation of the vehicle. The axle-to-beam connection is also unique in that the axle is resiliently attached to the beam without affecting the structural integrity of the beam.

摘要： Provided is a lift axle suspension system employing an extendible air chamber in which the lifting mechanism is located. The mechanism for lifting the vehicle's wheels out of road engagement includes a spirally coiled spring connected to a reel having a cable wrapped around it. The unwrapped end of the cable is connected to the vehicle and the reel is connected to the suspension. When air is supplied to the air chamber it extends, lowering the wheels into road engagement. In doing so, the chamber acts against the normal bias of the spirally coiled spring, playing out the cable as the reel rotates. Release of air from the chamber causes the bias of the spring to automatically rotate the reel in the opposite direction which in turn takes up the cable and raises the wheels from the road surface. Preloading of the spring serves to hold the suspension firmly in its riding position. The predetermined length of cable to be played out serves as a stop or shock absorber against over-extension of the air chamber.

摘要： A suspension system includes a pair of spring beams with each spring beam pivotally mounted to a hanger bracket extending downwardly from a vehicle. An axle seat is mounted to an end of each spring beam and includes a passage extending therethrough. The spring beam passes through the passage formed in the axle seat and is permitted to deflect in response to vertical loads within the passage. A resilient bushing is positioned within the passage and intermediate the axle seat and the spring beam to permit the spring beam to assist in retaining the axle seat onto the beam, and to assure that the spring beam may flex along its entire length. The axle seat is retained on the spring beam by the pin connection extending through an eyelet formed in one end of the spring beam. In alternative embodiments, one end of the spring beam is movable relative to either the hanger bracket or the axle seat with the axle seat being retained on the spring beam by an adjustable link mounted via a pair of mounting pins to the hanger bracket or mounting hood and to the axle seat.

摘要： 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.

摘要： A suspension system which includes at least one beam, a support spring extending between the vehicle frame and the support beam and a lift spring extending between a lift bracket welded to the beam and the vehicle frame. The support spring is precompressed by using a U-bolt and may be adjusted by increasing or decreasing the length of the U-bolt. Additionally, the spring provides a constant effective force throughout the entire path of travel of the tire-wheel assemblies attached to the axle. While the axle force provided by the spring increases, the force operates through a changing lever arm relative to the pivot point to assure that the spring force operating through the lever arm remains substantially constant throughout the path of travel of the suspension system.

摘要： A tag axle assembly has a frame having a pair of hanger brackets, an upper cross tube and a lower cross tube. A pair of rocker beams having a primary pivot for pivotally mounting the rocker beam to the support frame is mounted to the frame. A suspension air spring extends between the upper cross tube and each rocker beam, and a lift air spring extends between each hanger bracket and the front end of the rocker beam. An axle seat is hingedly mounted to the rear end of each rocker beam. An upper beam having an actuator beam and a lift bar are pivotally mounted to the axle seat and to the support frame. A linear actuator extends between the support frame and the actuator beam. Inflation of the lift air spring causes the rocker beams to rotate about the primary pivots, and expansion of the linear actuator causes the actuator beam and the interconnected lift bar to raise. As the interconnected lift bar raises, it applies an upward force to the axle seats such that the axle seats rotate about the hinge pins relative to the rocker beams. Such rotation causes the axle seats to raise further out of the ground engaging position and forward. To move the suspension into ground engaging position, the lift air springs are collapsed, and the effective length of the linear actuator is reduced while simultaneously, the suspension air springs are inflated to carry load.
