    • 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.
    • 牵引组件包括接收器部分,其包括空腔,容纳在空腔内的衬套构件以及包括枢转地容纳在衬套构件内的轴的连接构件。 衬套构件和轴之一由基本上不需要使用单独施加的润滑剂的材料构成。 连接构件还包括第一钳口构件,联接到第一钳口构件并且可在打开和关闭位置之间操作的第二钳口构件,与第二钳口构件联接的主闩锁,并且可在防止第二钳口构件的开口的锁定位置之间操作 以及允许打开第​​二钳口构件的解锁位置,以及与主闩锁联接的辅助闩锁,并且可在防止主闩锁解锁和解锁位置的锁定位置之间操作,其中主闩锁可以移动到解锁位置 。
