摘要:
A hitch assembly includes a receiver portion including a cavity, a bushing member received within the cavity, and a hitch member that includes a shaft pivotally received within the bushing member. One of the bushing member and the shaft is constructed of a material that substantially eliminates the need for using a separately applied lubricant. The hitch member also includes a first jaw member, a second jaw member coupled to the first jaw member and operable between open and closed positions, a primary latch coupled with the second jaw member and operable between a locked position preventing opening of the second jaw member, and an unlocked position allowing opening of the second jaw member, and a secondary latch coupled with the primary latch and operable between a locked position preventing unlocking of the primary latch and an unlocked position, wherein the primary latch may be moved to the unlocked position.
