Abstract
In many types of construction machines, the frame assembly comprises a rear frame that supports the engine and the majority of the drive train components and a front frame that supports the work implement and related structure. In this type of machine, the two frames are normally pinned together and the front frame is articulated with respect to the rear frame by a pair of steering cylinders to provide steering for the machine. In order to provide the required structural support for the components of the work implement and to accommodate the steering forces, the front frame is necessarily quite large. The present invention provides a front frame (12) structure that includes a pair of main side plates (62, 64) and a substantially planar support plate (74) that is mounted to a first end portion of the side plates (62, 64). The support plate (74) mounts an axle assembly directly thereto and defines a pair of mounting bores (84) that are positioned, on a rearmost portion of the support plate (74). The bores define a mounting point for the steering cylinders (32) which are mounted between the front and rear frames (12, 14) in an orientation that is substantially in line with the support…
