Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
An articulated vehicle comprising a prime mover portion and a wheeled load supporting portion interconnected by an articulated structure, said prime mover portion being provided with a power source, driven wheels and a power transmission for transmitting drive between said power source and said wheels, said prime mover portion further including a cast structure for providing chassis support for said power source and said power transmission, said articulated structure comprising an elongated frame positioned beneath said prime mover portion and a turntable carried by said frame, said turntable being journalled to said load supporting portion for permitting relative rotation between said prime mover portion and said load supporting portion about a substantially vertical axis, said frame having spaced bearing means defining a pivot axis parallel to and vertically in line with a longitudinal central axis of said prime mover portion, said cast structure being journalled adjacent its front and rear end portions in said spaced bearing means for pivotal movement of said prime mover portion upon said frame about said axis for isolating stresses of said load supporting portion from said prime mover portion.
