A towing system for trucks, such as traction cables or drawbars is provided, which is made up of a central body with two anchoring yokes, a rear one and a front one, located at each end of the central body. The system is characterized in that the anchoring forks have pivot lugs that allow their connection to the central body by means of bolts, with the forks having hydraulic anchoring cylinders at their ends to connect the system to trailers and towed trucks. The central body has a set of rear wheels and a set of front wheels for its movement, which, by means of a remotely controlled hydraulic system, allows the wheels to be raised. Mounted on the main body, between the rear wheel assembly and the front wheel assembly, is a hydraulic power pack that allows all towing functions to be performed automatically.

An article of manufacture for providing a theft-proof trailer hitch tongue is disclosed. The trailer hitch tongue has two or more mating receivers coupled to a trailer each of the two or more mating receivers having a plurality of locking notches about an inside surface of each mating receiver in a specific orientation, two or more removable arms for engaging the two or more mating receiver, each of the removable arms having a hitch tongue end and a connecting end and together form a split tongue of the trailer hitch, a plurality of locking pegs arranged on each of the two or more removable arms, the plurality of locking pegs being configured to simultaneously engage the plurality of locking notches when the hitch tongue end of the removable arms are inserted in the corresponding mating receiver, and locking latches components on the connecting end of each of the removable arms, the locking latches couple together after the hitch tongue end of the removable arms are inserted in the corresponding mating receiver.

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.

The present invention relates generally to a weight distribution system, and; more specifically, the present invention relates to a system of distributing weight of a towed vehicle to a towing vehicle and controlling sway of the towed vehicle relative to the towing vehicle. In one embodiment, the present invention relates to various different embodiments of a variable load rating spring arm (or spring bar) for a weight distribution systems.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a tension member comprising a top end configured to be supported by a frame member of the trailer, and a bottom end configured to support the rearward end of the moment bar, and a spring, configured to bias the moment bar rearward end toward the frame member of the trailer; and wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.

A system for powered trailer weight distribution having a hitch mount with a spring bar, and a trailer with a spring bar mount disposed on the trailer and having an initial position relative to the trailer, wherein the spring bar mount is configured to receive and engage the spring bar, and a weight distribution actuator configured and arranged to adjust a position of the spring bar mount relative to the spring bar while engaged with the spring bar, wherein the weight distribution actuator is connected to a power source that provides power to the weight distribution actuator, facilitating the adjustment of the position of the spring bar mount.

A weight distribution hitch system comprising a vehicle attachment member comprising a forward end configured to rigidly attach to a vehicle, and a rearward end extending rearwardly toward a trailer, the rearward end comprising an upper portion comprising a trailer attachment member configured to pivotally attach to a coupler of the trailer, and a lower portion configured to receive a moment bar; a moment bar having a modulus of elasticity, the moment bar comprising a moment bar forward end attached to the lower portion of the rearward end of the vehicle attachment member so as to prevent rotation about a horizontal axis, and a moment bar rearward end; a releasable tension member comprising a top portion configured to be pivotally supported by a frame member of the trailer and configured to pivot about a horizontal axis, and a bottom portion configured to support the rearward end of the moment bar; and a moment bar preload mechanism configured to push up the moment bar rearward end to thereby preload the moment bar; wherein, when the moment bar rearward end has been preloaded, the releasable tension member can be pivoted between a first angular position and a second angular position below the preloaded moment bar; wherein, when the tension member is in tension, it imposes an upward force on the moment bar rearward end, which, in turn, imposes a forward moment on the vehicle is disclosed.
