摘要： In many types of construction machines, the frame assembly comprises a rear frame that supports the engine and drive train components and a front frame that supports the work implement. 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 the area in which the two frames are pinned together it is necessary to provide structural support, especially in the hitch area of the front frame. The present invention provides a front frame assembly (12) that has an upper and lower hitch plate (118, 120) that are positioned between and secured to the rear portion of a pair of side plates (62, 64) defined by the front frame assembly (12). A first support plate (128) extends between and is secured to the side plates (62, 64) and defines an upper and lower end portion (172, 176) that are secured to the respective upper and lower hitch plates (118, 120) to provide uninterrupted support therebetween.

摘要： 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 plate to transmit the forces from the steering cylinders (32) directly into the support plate (74).

The present invention provides a front frame (12) structure that includes a pair of main side plates (62, 64) that are positioned a preselected distance (W) from one another and mount a lift arm assembly (30) therebetween to minimize the overall width of the frame assembly. The forward end portion of the front frame assembly (12) has a preselected height (H) that permits the front frame to have a low profile. These features provide a frame assembly that allows an operator exceptional visibility to the work implement (42).
