ABSTRACT:
Embodiments described herein relate to methods and structures that can be used to quickly disconnect a trailer from a tractor. One embodiment provides a quick disconnect hitch that links a tractor and a trailer. The quick disconnect hitch comprises a tongue attached to the tractor and a body insertable into the tongue. An extension is attached to and projects away from the body. The extension is connectable with the trailer. A pair of lugs is disposed on the body. The lugs are movable between a connected position where the trailer moves responsive to movement of the tractor and a disconnected position where the trailer moves independently of the tractor. A detent is disposed on each of the pair of lugs. A pair of slots is disposed on the tongue. Each of the pair of slots is configured to accept the detent. Each detent is disposed in each of the pair of slots when the lugs are in the connected position, and each detent is dislocated from each of the pair of slots when the lugs are in the disconnected position.
