Abstract: Brackets for mounting auxiliary suspension systems, such as lift axle systems, to vehicles are disclosed herein. For example, brackets are disclosed for attaching lift axle hanger brackets and lift axle load springs to corresponding frame members. In some embodiments, the frame brackets can include physical features (e.g., a series of graduated steps in an edge portion thereof) to facilitate visual alignment of the lift axle with the vehicle frame members during installation. In other embodiments, the frame brackets can be two-piece brackets that enable the load springs to be removed and replaced without having to detach the frame bracket from the frame rail.

Abstract: Lift axle systems for use with trucks and other heavy duty vehicles are described herein. In some embodiments, lift axle systems configured in accordance with the present technology include upper and lower control arms on each side of the vehicle that operably couple an axle to a support system attached to the vehicle chassis. The upper control arm has a first end portion pivotally attached to a support system bracket at an upper bracket location, and a second end portion pivotally attached to the axle at an upper axle location. The lower control arm has a first end portion pivotally attached to the support system bracket at a lower bracket location, and a second end portion pivotally attached to the axle at a lower axle location.

Abstract: An auxiliary axle or lift axle is pivotally mounted to the frame of a vehicle for selectively providing additional flotation for the vehicle. A pair of frame brackets are secured to the frame members of the vehicle and have horizontally disposed mounting plates adjacent to the lower ends thereof. A bracket member extends downwardly from one end of the mounting plate and has a pair of spaced-apart slots formed therein. A bracket member also extends downwardly from the other end of the frame bracket and has a pair of spaced-apart first and second slots formed therein. The hanger brackets are adjustably secured to the bracket members to permit the axle assembly to be mounted on frame members having varying distances therebetween and having varying frame thicknesses. The novel method of securing the hanger brackets to the frame brackets is also disclosed.

Abstract: An adjustment mechanism for adjustably aligning the bushing pin of a hanger bracket to which a lift arm of a lift axle suspension system is secured. The adjustment mechanism may also be used for adjustably aligning the bushing pin of an auxiliary axle which is of the non-lift type. The adjustment mechanism may also be used for adjustably aligning the bushing pin of a primary axle. More particularly, the invention relates to an adjustable alignment mechanism of the type described which includes an improved pointer device which visually indicates the alignment position of the bushing pin. Even more particularly, this invention relates to an improved means for securing the bushing pin in its aligned position.

Abstract: A cart or load lift is disclosed which is positioned within the body of a box truck or the like inwardly of a door opening formed in the side or rear of the box truck. The lift includes a load support located on the outer ends of a pair of parallel arm assemblies so that the load support may be moved from a stowed position within the vehicle to a lowered position outwardly of the vehicle to enable a cart or load to be positioned thereon and then raised upwardly and inwardly into the vehicle.
