In some embodiments, the first end plate 11 and the second end plate 13 of the track shoe body 1 are detachably connected to the main board body 12, and further, when the first side surface and the second side surface of the main board 12 are worn down, only the main board 12 can be replaced, and the original first end plate 11 and second end plate 13 are mounted to a new main board 12, so that maintenance cost is further reduced. Meanwhile, the first end plate 11 and the second end plate 13 may be manufactured separately from the body plate 12, contributing to a reduction in production difficulty.
In some embodiments, the first side and the second side of the main board body 12 are the same shape. This arrangement helps to ensure the use effect when continuing to use after turning over the track shoe body 1.
In some embodiments, the main board body 12 is a flat board structure. This arrangement helps to facilitate installation between the track 2 and the track plate body 1.
In some embodiments, as shown in fig. 2 to 6, the combined track shoe further includes a shaft type fastener and a track link 3, a first mounting hole is provided on the track link 3, a second mounting hole 21 and a third mounting hole 121 corresponding to the first mounting hole are provided on the track 2 and the track shoe body 1, and the shaft type fastener passes through the first mounting hole, the second mounting hole 21 of the track 2 and the third mounting hole 121 of the track shoe body 1 simultaneously to fasten the track link 3, the track 2 and the track shoe body 1 into a whole. The arrangement can enable the structure of the combined track shoe to be more compact, and the arrangement of fasteners is reduced.
In some embodiments, the shaft fastener is a threaded fastener comprising a bolt and a nut that cooperate with each other, and the second mounting hole 21 is a stepped through hole comprising a large bore hole and a small bore hole that are connected to each other, the large bore hole cooperating with the nut of the bolt to receive the nut. In this embodiment, the bolt with the nut passes through the stepped through hole of the track 2, and passes through the third mounting hole 121 of the track plate body 1 and the first mounting hole of the track link, and the track link 3, the track plate body 1 and the track 2 are fastened together by cooperating with the nut. By providing the stepped through hole, the nut is accommodated in the large-aperture hole, and the nut can be prevented from protruding outside the crawler 2.
In some embodiments, as shown in fig. 2, 3 and 5, the track shoe body 1 is further provided with a lightening hole, where the lightening hole includes an elongated hole and/or a round hole. The combined crawler belt is light due to the fact that the lightening holes are formed, and meanwhile sediment of the combined crawler belt can be leaked through the lightening holes.
In some embodiments, a track assembly is disclosed, including a modular track shoe of any of the embodiments.
As shown in fig. 7, in some embodiments a crawler running gear is disclosed that includes the crawler assembly described above.
In some embodiments, a work machine is disclosed that includes a track assembly as described above.
