A recreational vehicle includes a frame, left and right air suspensions, a front jack, a tilt sensor configured to measure lateral and longitudinal tilt data associated with the frame, and a controller. The controller is configured to receive the lateral and longitudinal tilt data to thereby level the frame laterally via operation of the left and right air suspensions and level the frame longitudinally via operation of the left and right air suspensions and the front jack. Methods for performing a leveling operation include utilizing left and right air suspensions of the recreational vehicle in combination with operating a front jack of the recreational vehicle until the recreational vehicle is level along lateral and longitudinal axes.

A towable vehicle including a chassis, at least two wheels and a suspension assembly supporting each wheel. The suspension assembly includes a swing arm pivotally mounted to the chassis, an axle mounted proximate an end of the swing arm, the wheel being mounted on the axle, at least one shock absorber extending from the chassis to the swing arm, an airbag swing arm mounting pivotally coupled to the swing arm, an airbag chassis mounting coupled to the chassis, an airbag coupled to the airbag swing arm and airbag chassis mountings so that inflation of the airbag allows a suspension height to be adjusted over an operating range and a pivot arm pivotally mounted to the chassis and the airbag swing arm mounting to maintain an orientation of the airbag swing arm mounting over the operating range.

The present application pertains to a system comprising a multi-axle trailer with a front and a rear. The a multi-axle trailer comprises at least one lift axle configured to be raised or lowered to distribute weight, to increase trailer deflection during a turn, or both. A jeep is mounted between the trailer and a tractor wherein the jeep is configured to decrease weight on one or more axles. A booster is mounted to the rear of the multi-axle trailer. The system is configured such that during raising of the at least one lift axle an increase in air pressure to one or more other axles is increased to offset weight.

A pneumatic automotive height adjuster assembly provides at least one bag removably connected to a vehicle having a frame. The at least one bag is configured to adjust a height of the frame. An air supply line has a supply end and a discharge end. The discharge end is in fluid communication with each of the at least one bag. The air supply is configured to provide air to inflate the at least one bag. A switch is in fluid communication with the supply end of the air supply line. The switch has a first discharge, a second discharge, and a switch input. A leveling valve is in fluid communication with the first discharge. The air supply line is in fluid communication with the second discharge. An air supply is in fluid communication with the leveling valve and the switch input.

The application discloses a Drop Deck Trailer having a pivoting axle system that allows the deck of the trailer to be incrementally lowered to the ground. When coupled to a tow vehicle, the partially lowered deck becomes a ramp to load and unload a vehicle. The unloaded trailer can be backed into a standard garage, uncoupled, and lowered completely to the ground. The UTV or light vehicle can then be front-loaded on the trailer. This capability allows the convenience and cost savings of simultaneously storing a UTV or other light vehicle in the same standard garage space. A unique articulated tongue assembly allows the operator to minimize the footprint of the parked trailer, allowing smaller spaces to be used for storage or simply eliminate a trip hazard. The Drop Deck Trailer is a combination of innovative features that provides convenience and cost savings.

A suspension axle for a farm equipment is provided. The suspension axle includes an axle beam having two ends. The two ends are configured to be simply supported to the farm equipment. The suspension axle also includes a first mounting arm coupled to the axle beam between the two ends and extending outwardly from the axle beam. The suspension axle also includes a first mounting bracket pivotably coupled to the first mounting arm at a first horizontal pivot axis. The suspension axle also includes a first suspension member coupled to at least one of the axle beam and the first mounting arm.

An equalizer includes a pivot arm pivotally connected between first and second spaced-apart plates fixedly connected to each other. First and second bump stops extend from one of the first and second plates to or toward the other of the first and second plates. A first shock absorber is disposed and selectively compressible between the pivot arm and the first bump stop. A second shock absorber is disposed and selectively compressible between the pivot arm and the second bump stop.

A retractable wheel assembly includes arm assemblies, wheels, a retraction arm, and a threaded shaft. The arm assemblies are hingedly attached to a lower frame of a utility vehicle. Each arm assembly comprises a first arm, a second arm, and a third arm hingedly linked there between. Each wheel is connected to the third arm of each arm assembly. The retraction arm is connected to the second arm, and a threaded shaft. The threaded shaft is configured to be actuated rearwardly where the retraction arm is rearwardly pulled causing the second arm to unfold the arm assembly outwardly and deploy the wheels and for motion of the utility vehicle. Then, the threaded shaft is configured to be actuated forwardly where the retraction arm is pushed forward causing the second arm to fold the arm assembly inwardly and fold the wheels and when the utility vehicle is positioned at rest.

A torsion axle arrangement is provided wherein the spindle is mounted to the suspension link by insertion into a split socket at one end of the suspension link, which is inclined with respect to the longitudinal axis of the suspension link. That connection is maintained by a bolt passing through the suspension link, engaging a mating groove in the spindle, and then clamping the ends of the split socket together. The bolt is anchored to the suspension link by a threaded connection external to the suspension link. A chamfer or surface recess is formed in the surface of the suspension link for immediate source identification.

An axle arrangement for a baler having a chassis includes a first axle having opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the first axle to accommodate generally vertical loads. The first axle is coupled with the chassis to accommodate generally horizontal loads. A second axle has opposite ends and a pair of suspension cylinders, with each suspension cylinder positioned at a corresponding end of the second axle to accommodate generally vertical loads. The second axle is coupled with the first axle to accommodate generally horizontal loads.
