摘要： A fifth wheel hitch assembly is provided for use with a kingpin, the hitch assembly including a hitch frame including a throat for receiving the kingpin therein, a jaw member pivotally coupled to the hitch frame and moveable between an open orientation and a closed orientation, and a locking arm having a cooperative relationship with the jaw member. One of the jaw member and locking arm defines a guide surface and another of the jaw member and locking arm includes a follower configured to traverse the guide surface, traverse of the follower along a guide segment of the guide surface directing rotation of the jaw member between the open orientation and the closed orientation, and traverse of the follower along a lock segment directing releasable locking of the jaw member in the closed orientation.
