A hanger for axle/suspension systems of a heavy-duty vehicle includes an outboard wall spaced apart from an inboard wall. The outboard wall is connected to the inboard wall via a front wall. The outboard wall and the inboard wall are formed with an aligned opening extending through the outboard wall and the inboard wall. A top plate connected to the inboard wall, the outboard wall and the front wall. The top plate is formed with at least one circular opening or laterally oriented oblong-round opening and at least one laterally slotted opening. A fastener is disposed through the at least one circular opening or oblong-round opening. A second fastener is disposed through the at least one laterally slotted opening for mounting the hanger to a frame of the heavy-duty vehicle.

A method and apparatus for lowering the height of a wheeled vehicle for cargo height constraints during transportation. The rear leaf spring shackle on each side of the vehicle is connected to a sliding frame mount. In the transport configuration, fasteners are removed from the sliding frame mount, and the mount slides forward, rotating the rear leaf spring shackle from a near vertical to a near horizontal position, effectively lowering the height of the vehicle. To return the vehicle to the ride configuration, a screw jack member is attached to the sliding frame mount and a rear attachment point on the vehicle, pulling the sliding frame mount back, aligning attachment points of the mount with the frame member in the original position. The fasteners are reinstalled to lock the sliding frame mount into the ride configuration.

A method for assembling an agricultural vehicle including the initial step of providing the agricultural vehicle including a frame, a hydraulic manifold, and a cab suspension system. The cab suspension system includes an anti-roll bar, a pair of support brackets configured for securing the anti-roll bar to the frame, and a pair of intermediary placement brackets configured for temporarily supporting the anti-roll bar in a final assembly position. The method includes the further steps of attaching the intermediary placement brackets onto the frame, positioning the anti-roll bar on the intermediary placement brackets to position the anti-roll bar in the final assembly position, assembling the hydraulic manifold onto the frame, and connecting the support brackets to the frame and the anti-roll bar.

A tandem axle assembly includes a first slipper spring and a second slipper spring. The two slipper springs are configured or oriented in series with the slipper ends of the two slipper springs oriented toward each other. A keeper for a tandem axle suspension assembly is also disclosed.

A suspension assembly for a vehicle may have a first end for pivotal mounting to a structural member of the vehicle and a second end opposite the first end for attachment of a damping arrangement and a stub axle. The suspension assembly may include first and second shell components that are welded together to form a substantially hollow body between the first and second ends.

Disclosed is a self-balancing device for self-propelled off-road RV box body. The self-balancing device includes an auxiliary beam body for connecting with a bottom end of the RV box body, a front triangular balance beam body, a rear triangular balance beam body and an axle-holding device for connecting with a RV chassis girder. The front triangular balance beam body and the rear triangular balance beam body are arranged close to both ends of the auxiliary beam body respectively. The axle-holding device is arranged between the front triangular balance beam body and the rear triangular balance beam body. Both the front triangular balance beam body and the rear triangular balance beam body include a hard limit structure for limiting a swing angle of the RV box body. The axle-holding device includes a soft limit structure for horizontally resetting the RV box body.

A bearing device for mounting an axle guide for commercial vehicles includes a first connector which has an axial direction of extension, and a first axial centre in the axial direction of extension, a damping unit, having an outwardly peripheral retaining surface, and a second connector being fixed to the retaining surface, wherein the second connector extends along the axial direction of extension, wherein the second connector has a boundary surface on which an axle guide can be fixed, wherein the boundary surface has a second axial centre in the axial direction of extension, and wherein the first and the second axial centre are offset from each other along a vector of the axial direction of extension.

A status display, in particular for use on the wheel suspension of a vehicle, includes a first reference unit and a second reference unit, wherein the first and the second reference unit are mounted or fastened to one another via a holding unit, wherein the first reference unit has a first reference geometry, wherein the second reference unit has a second reference geometry, the position of the first reference geometry relative to the second reference geometry being able to be determined optically or haptically by a user, at least in a wear condition of the holding unit.

A spring hanger assembly may be formed pieces shaped to increase the stiffness and strength. The spring hanger assembly may comprise separate pieces, such as an inner section and an outer section. The spring hanger assembly may be attached to a frame using fasteners or hucks.

A vehicle suspension system may include a first suspension assembly operably coupling a first wheel to a chassis of a vehicle, a second suspension assembly operably coupling a second wheel to the chassis where the first and second wheels form a pair of front wheels, a third suspension assembly operably coupling a third wheel to the chassis, a fourth suspension assembly operably coupling a fourth wheel to the chassis where the third and fourth wheels forming a first pair of rear wheels, and a payload extension kit that is attachable to the chassis non-permanently. The payload extension kit may include a fifth suspension assembly operably coupling a fifth wheel to a sub-frame extension of the payload extension kit, and a sixth suspension assembly operably coupling a sixth wheel to the sub-frame extension, where the fifth and sixth wheels form a second pair of rear wheels.
