CA 2525721

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.

Cette invention concerne un ensemble d'attelage comprenant une partie récepteur comprenant une cavité, un élément de bague logé dans la cavité et un élément d'attelage comprenant un arbre logé pivotant dans l'élément de bague. L'élément de bague ou l'arbre est fabriqué dans un matériau qui élimine sensiblement le besoin de recourir à un lubrifiant appliqué séparément. L'élément d'attelage comprend également un premier élément de griffe, un second élément de griffe couplé au premier élément de griffe et pouvant passer d'une position ouverte à une position fermée et inversement, une clavette principale couplée au second élément de griffe et pouvant passer d'une position verrouillée empêchant l'ouverture du second élément de griffe à une position déverrouillée permettant l'ouverture du second élément de griffe et inversement, ainsi qu'une clavette secondaire couplée à la clavette principale et pouvant passer d'une position verrouillée empêchant le déverrouillage de la clavette primaire à une position déverrouillée permettant le déverrouillage de la clavette principale et inversement.
