STEERING LINKAGE ARRANGEMENT FOR ARTICULATED MOBILE MACHINE

摘要

A front frame is disclosed for an articulated machine. The front frame may have a central tilt structure with parallel plates, a web member disposed between and connecting the parallel plates, and a hinge component connected to the web member. The front frame may also have mounting lugs connected to the web member opposite the base, the mounting lugs being configured to receive a pivot pin of a tilt cylinder. The front frame may further have two substantially identical lift structures located at sides of the central tilt structure, the lift structures being configured to receive spaced apart lift arms. The front frame may additionally have an axle mounting pad connected at a base of each of the lift structures and configured to engage a front axle of the articulated machine, and a bearing bore located adjacent the axle mounting pad and configured to receive a pivot pin of a steering cylinder.
