The present invention is directed to a trailer vehicle apparatus comprising a trailer body, an axle, and a truss suspension structure (TSS). The axle comprises a shaft traversing the trailer body width. TSS comprises first and second platforms and truss structures. The first and second platforms comprising a first and second proximate end, respectively. Each truss structure is: perpendicularly oriented relative to the top surface of the platforms; affixed to corner nodes of the first and second proximate ends; and comprises a strut channel perpendicularly oriented relative to the top surfaces of the platforms as well as traverses a length of the truss structure. TSS is affixed to a bottom surface of the trailer body. The axle shaft comprises strut structures each slidably mounted within a strut channel. Strut structures are configured to traverse the strut channel as the trailer vehicle converts between a mobile state and a stationary state.

The ball socket assembly includes a housing that is made as a monolithic piece and has an inner bore. The ball socket assembly also includes a ball stud that has a semi-spherically curved portion, a cylindrical portion, and a shank portion. The ball socket assembly further includes a backing bearing and an exit bearing. A third bearing is received on the cylindrical portion of the ball stud. The third bearing has a curved outer surface which cooperates with the curved inner surface of at least one of the exit and backing bearings for allowing the ball stud and the bearing to articulate and rotate relative to the housing. The third bearing is also in slidable contact with the cylindrical portion of the ball stud for allowing the ball stud to more freely rotate relative to the housing about the central axis.

An axle system includes an axle stub and a clamping unit, the axle stub being formed in a substantially rotationally symmetrical manner about a stub axis, the clamping unit in an assembled state transmitting a clamping force to the axle stub, the clamping unit and the axle stub in the assembled state being secured non-positively to prevent movement relative to one another.

An axle assembly includes a central tube and an axle spindle. The axle spindle is fixed to the central tube. The axle spindle has a tubular first section and a tubular second section extending from the first section. The second section has an outer diameter. The second section has a bearing support surface. A tubular transition section is located between the first section and the second section. An annular shoulder portion is formed in an axial end segment of the tubular transition section adjacent the second section. The shoulder portion has at least one annular profile located in the shoulder portion between the annular shoulder surface and the bearing support surface. The annular profile is defined by a surface with a diameter not less than the outer diameter of the second section. An antilock braking system sensor bracket locator nub is integrally formed in the tubular transition section. An antilock braking system sensor bracket engages the antilock braking system sensor bracket locator nub for proper positioning of an antilock braking system sensor.
