Embodiment Construction

[0017] reference figure 1 , A ground joining machine 10 according to an embodiment is shown. The machine 10 is shown in the description of an articulated wheel loader, which has a frame 12 including a first frame unit 14 and a second frame unit 26 coupled to the first frame unit 14. The first set of ground engaging elements 22, which may be ground engaging wheels, are coupled to the frame unit 26, and the second set of ground engaging elements 24, which may also include ground engaging wheels, are coupled to the frame unit 14. The engine 38 may be mounted to the frame unit 14, and the cab 36 with the operator control station 40 positioned therein is also mounted to the frame unit 14 in a conventional manner. The execution system 34 including, for example, a bucket, a lifting arm, and an actuation system is shown coupled to the frame unit 26. The frame unit 14 may further include a first peg plate 16 and a second peg plate 20, and the frame unit 26 may include an intermediate p...

Abstract

A ground engaging machine includes first and second frame units and an articulation hitch coupling the first and second frame units together. The hinged hitch includes a pin, a first bearing positioned around the pin and adjacent to a first axial side and a second axial side of an annular protrusion of the hitch plate in one of the first frame unit and the second frame unit, and a second bearing. bearings. The clamping mechanism of the hinged hitch clamps the first bearing and the second bearing between the first clamping part and the second clamping part, preloading them against the annular protrusion.

Description

Technical field [0001] The present invention relates generally to an articulated machine, and more particularly to an articulated hook for such a machine, in which a bearing is clamped between a first clamping part and a second clamping part, and abuts against the machine frame The annular protrusion of the unit is preloaded. Background technique [0002] Articulated machines are used in a wide range of heavy-duty applications. In general designs, such as any of a variety of wheel loaders used in construction, mining, forestry, and garbage disposal, a set of front wheels are connected to the front frame unit, and a set of rear wheels are connected to the rear frame unit . The frame unit is hinged around the hinge axis at one or more hinge joints. An articulated steering system will typically include hydraulic actuators that force the frame units to rotate relative to each other about the articulation axis. Articulated machines generally have very dynamic operations, repeatedl...
