A fifth wheel hitch assembly for mounting to a towing vehicle and receiving a kingpin of a trailer incorporating a comfort assembly is provided. The fifth wheel hitch assembly may comprise a kingpin receiving assembly attached to a mounting rail via a comfort assembly. The comfort assembly may include one or more pivot bushing assemblies, as well as vertically adjustable, anti-rattle attachment systems. These attachment systems may include a cam assembly and/or a T-pin assembly.

A transport system can employ a transport assembly with a main support member attached to a mounting connection, a tow connection, a suspension, and a horizontal articulation mechanism. The horizontal articulation mechanism may be configured to raise the suspension of a ground surface along a first direction and move the main support member in a second direction with the first direction being orthogonal to the second direction.

A selectively lowerable and raisable vehicle trailer system for raising and lowering of a vehicle trailer to expedite loading and unloading of cargo includes a rear wheel assembly. An elongated trailer is pivotally supported by the rear wheel assembly. The trailer is positional between a horizontal transport orientation and a sloped or angled loading/unloading orientation on the rear wheel assembly. The rear wheel assembly is selectively adjustable in position along the trailer between a rear transport position and a forward loading/unloading position, rearward and forward of the trailer center of gravity, respectively. A wheel assembly adjustment mechanism engages the rear wheel assembly. The wheel assembly adjustment mechanism operably engages the rear wheel assembly to facilitate selective positioning of the rear wheel assembly between the transport position and the loading/unloading position. A method of loading and unloading cargo onto and from a vehicle trailer is also disclosed.

A quick connect logistics trailer used with a forked vehicle, where the trailer includes two movable fork guides to attach to the forks of the forked vehicle, a fork guide spacer to move the fork guides to accommodate different fork spacing, and a movable top platform attached by hinges to allow access to components under the top platform. The quick connect logistics trailer also includes side mounted fork pockets to lift the logistics trailer. The quick connect logistics trailer also includes two linear latches attached to the fork guides that can be attached to the forks of the vehicle, and two switchable magnets attached to each fork guide to attach the fork guides to the forks. The quick connect logistics trailer can also include a trailer clip attached to the trailer and a fork truck clip assembly attached to the forked vehicle, where the trailer clip assembly temporarily but securely attaches to the fork truck clip assembly to allow the forked vehicle to tow the logistics trailer.

A vehicle for transporting cargo includes a front end unit having a front wheel, a rear end unit having a rear wheel, and a carrying unit on which the cargo is loaded and which is interposed between the front end unit and the rear end unit so that the front end unit and the rear end unit are coupled to each other via the carrying unit. The carrying unit is configured to be separated from the front end unit and the rear end unit in a direction intersecting a direction in which the vehicle travels and to be coupled to the front end unit and the rear end unit while the front end unit and the rear end unit are stationary.

A tractor that includes: a driver equipped with a left and right pair of driving wheels; a vehicle main body provided between the left and right pair of driving wheels; a periphery information detection sensor provided at the vehicle main body and detecting periphery information; a controller provided in the vehicle main body and controlling autonomous traveling by the driver in accordance with the periphery information detected by the periphery information detection sensor; and a first coupler provided at the vehicle main body and configured to be coupled to a trailer.

Methods and systems to assist maneuvering of a trailer being towed by a vehicle. The trailer includes a left wheel, a right wheel, an axle, a left brake device coupled to the left wheel, and a right brake device coupled to the right wheel. The methods and systems receive a driver command for a target path for the trailer, determine a left braking torque for the left wheel and a right braking torque for the right wheel based on the target path so as to provide for differential braking, and apply, via the left brake device and the right brake device, the left braking torque and the right braking torque to assist maneuvering of the trailer along the target path.
