ABSTRACT:
A material handling vehicle is provided with an articulating and an oscillating hitch assembly between a tractor portion and a trailer portion thereof. The hitch assembly telescopes a pinion gear support or trunnion housing carried by a differential gear housing into an oscillation housing. The oscillation housing is pivotally connected to the tractor and permits the tractor to pivot about a generally vertical axis and to oscillate about a longitudinal axis of the housing, both oscillation and pivoting being relative to the trailer as the vehicle is propelled over a terrain. The telescoping of the pinion gear or trunnion housing and oscillation housing makes it possible to eliminate parts and effectively shorten the length of the vehicle without sacrificing any flexibility or strength in the hitch assembly between the tractor and the trailer.
