Embodiment Construction

[0075] figure 2 A machine 10 having a chassis 12 with an undercarriage system 14 according to the present disclosure is shown. The machine 10 may be any type of machine including a crawler undercarriage system 14. in figure 2 In the example shown, the machine 10 is an excavator having an upper structure 16 pivotally supported on a chassis 12. In this embodiment, the machine 10 may include a tool 18, which may have a digging bucket 20 attached to the tool 18 for digging. Alternatively, the machine 10 may be another type of machine, including, but not limited to, a crawler tractor.

[0076] The underframe 14 may be configured to support the machine 10 and move it along the ground, road surface, and / or other types of terrain. Such as Figure 3A with Figure 3B As clearly shown, the underframe 14 may include a track roller frame 22, various guide members connected to the track roller frame 22, and an endless track engaged with the guide members. in Figure 3A with Figure 3B In th...

Abstract

A roller for a machine undercarriage may include a roller body constructed from a single, unitary piece of parent material. The roller may also include a first roller tread disposed between a first end of the roller body and a second end of the roller body. Additionally, the roller may include a second roller tread disposed between the first and second ends of the roller body.

Description

Technical field [0001] The present disclosure relates to mobile machines, and in particular to a crawler type chassis for mobile machines. Background technique [0002] Many mobile machines have a crawler-type underframe, which moves along the ground as the machine moves. For example, many earth moving machines such as tractors and excavators may have such underframes. In the known chassis design, many parts have a complicated geometric design, which leads to a relatively high manufacturing cost. Figures 1A-1C provide examples of certain chassis components and their complex designs. [0003] FIG. 1A shows a part of a chain link assembly 400 in the prior art, which serves as a flexible support for the endless track of the underframe. The chain link assembly 400 includes a plurality of chain links 401 assembled into laterally spaced chain link pairs, and the chain link pairs are connected to each other on a pivot joint 403. Each link 401 includes a side surface 402. In addition,...
