This disclosure relates to systems and methods of towing, hitching, and connecting devices. In particular, this disclosure relates to tow devices, hitches, and connections for towing item containers behind vehicles, both autonomous and manually guided.

A lift and tow module for use with a trailer and method of towing a trailer with a truck. The module has an arm having a connection point for securing to a tow vehicle and a lift body having a connection point for securing the lift body to a trailer. The connection point comprises at least two connection mechanisms spaced apart on the main body for connection to corresponding mechanisms on the trailer. A support plate is extendable from and operably supported by the main body and the lift body is movable in reciprocal directions. Mechanical actuators are operably coupled to the body and the arm for controlling respective movement, which allows the module to jack up a trailer, connect to a trailer, and/or tow a trailer.

A controlled-flexing trailer hitch system and method to facilitate vehicle-to-trailer attachment and maneuvering by providing a flexible state during attachment, detachment, and low-speed maneuvering of a trailer, and automatic change to a fixed in-line state upon the in-line pulling of the trailer, by providing disengageable spring-return stiffening members and a flexible segmented towing member, where the spring-return stiffening members can be disengaged to allow flexible movement of the flexible towing member, and where, upon commencement of the in-line pulling of the trailer, the spring-return stiffening members engage to place the controlled-flexing trailer hitch into a fixed in-line state.

A hitch system for distributing weight from a trailer to the wheels of a towing vehicle. The system has a hitch head that is pivotally connected to a hitch bar and is pivotable about a hitch head axis with respect to the hitch bar. A hitch pin is rotatably fixed to the hitch head and the hitch pin is rotatable with respect to the hitch head about a hitch pin axis. The hitch pin axis is transverse to the hitch head axis. A single spring is pivotally connected to the hitch head and is pivotable with respect to the hitch head about a spring axis. A distal end of the spring spaced from the spring axis is connectable to the trailer when the trailer is connected to the hitch pin and the spring can provide a biasing force when the distal end of the spring is moved nearer the trailer.

A wheeled assembly configured to support a trailer. The wheeled assembly includes a frame, a pair of wheels coupled to the frame, a tongue hingedly coupled to a front end portion of the frame that is configured to rotate between a deployed configuration and a stowed configuration, a hitch coupler coupled to the tongue that is configured to connect to a tow vehicle, and a pair of stabilizing jacks coupled to opposite sides of the frame.

A trailer has a body frame and a tongue frame. The tongue frame has a trailer coupler at a first end and a second end that is movably attached to the body frame. The tongue frame is movable between an operational position and a stored position. The tongue frame is vertically offset from the body from such that a top of the tongue frame is lower than a bottom of the body frame. In the stored position, at least the majority of the tongue frame is positioned below the body frame. In the operational position, the tongue frame extends forward from the body frame and the second end of the tongue frame remains below the body frame. A locking mechanism holds the tongue frame in the operational position. At least one axle with wheels is provided.

A lift and tow module for use with a trailer and method of towing a trailer with a truck. The module has an arm having a connection point for securing to a tow vehicle and a lift body having a connection point for securing the lift body to a trailer. The connection point comprises at least two connection mechanisms spaced apart on the main body for connection to corresponding mechanisms on the trailer. A support plate is extendable from and operably supported by the main body and the lift body is movable in reciprocal directions. Mechanical actuators are operably coupled to the body and the arm for controlling respective movement, which allows the module to jack up a trailer, connect to a trailer, and/or tow a trailer.

Systems, assemblies, and an adapter arm are disclosed for connecting a tow bar assembly to a vehicle baseplate. The adapter arm comprises a forked end including a first prong and a second prong defining a slotted opening for receiving a lug connector of the tow bar assembly. The adapter arm further comprises a locking portion configured to removably secure the adapter arm to the vehicle baseplate.

This disclosure relates to systems and methods of towing, hitching, and connecting devices. In particular, this disclosure relates to tow devices, hitches, and connections for towing item containers behind vehicles, both autonomous and manually guided.

A stabilization system for an off-road trailer may include a hitch ball assembly, a tower assembly, and a stabilizer arm assembly. The tower assembly may include a pivot mechanism that allows the stabilizer arm assembly to pivot about a pivot axis relative to the hitch ball assembly. The stabilizer arm assembly may include one or more arms extending between the pivot axis and the off-road trailer and one or more piston damping assemblies extending between the arms and the off-road trailer. The piston damping assemblies may be configured to exert forces on the off-road trailer in response to the off-road trailer moving with respect to a towing vehicle to reduce further motion of the off-road trailer with respect to the towing vehicle.
