The invention relates to a caterpillar track section assembly and a caterpillar track system and engineering machinery comprising the caterpillar track section assembly. The caterpillar track section assembly comprises a left caterpillar track section, a right caterpillar track section, two bushings and a pin shaft connected with the left caterpillar track section and the right caterpillar track section. The left chain track section is provided with a first left hole and a second left hole; the right chain track section is provided with a first right hole and a second right hole; the two bushings are respectively mounted in the second left hole and the second right hole; the pin shaft comprises a middle section as well as a first section and a second section which are positioned on the two sides of the middle section, and the first section and the second section are respectively arranged in the first left hole and the first right hole in a penetrating manner in an interference fit manner and are jointed with the two bushings of the other chain track section assembly in a clearance fit manner; wherein the intermediate section has a projection configured to be engageable with a drive wheel of the construction machine. According to the caterpillar track section assembly, the protrusions are directly meshed with the driving wheel of the engineering machine, the number of manufacturing procedures of a caterpillar track system and even the whole engineering machine is reduced, and therefore the manufacturing cost is reduced.

    本发明涉及一种链轨节组件及包括该链轨节组件的履带系统和工程机械。该链轨节组件包括左链轨节、右链轨节、两个衬套和连接左右链轨节的销轴。左链轨节具有第一左孔和第二左孔;右链轨节具有第一右孔和第二右孔;两个衬套分别安装在第二左孔内和第二右孔内;销轴包括中间部段以及位于中间部段两侧的第一和第二部段,所述第一和第二部段分别以过盈配合的方式穿设在第一左孔和第一右孔中,并且旨在与另一个链轨节组件的两个衬套以间隙配合的方式接合;其中,中间部段具有构造成能与工程机械的驱动轮接合的凸起。本发明的链轨节组件通过将该凸起直接与工程机械的驱动轮啮合,减少了履带系统,甚至整个工程机械的制造工序,从而降低了制造成本。
