A RECOVERY TOW HITCH ASSEMBLY

机译:牵引拖车总成

摘要

There is provided herein a recovery tow hitch assembly which may be utilised in a standard configuration much like a conventional tow hitch assembly. However, during bogging, a locking mechanism may be unlocked so as to free a sliding member slidably retained within a sleeve. A compression member acts between the sliding member and the sleeve such that, when unlocked, the vehicle may be driven forwards free of trailer tow load until such time that the compression member acts on the extended sliding member to pull the trailer free. In embodiments, at the full extent of travel of the sliding member, the present tow hitch assembly initially jerks the trailer under the inertia of the vehicle and wherein the potential energy stored within the compression member further assist the freeing of the trailer wheels.
