FIG. 4B is a cross-sectional view along the sectional line 4-4 of the reinforcing unit 300 of the track shoe pad structure assembly 100 of FIG. 4A.

[0031] The track shoe pad structure assembly 100 which is connected to a track chain of a caterpillar vehicle (not shown in the figures) and includes a track shoe pad 200, a reinforcing unit 300 and an elastic element 400. The track shoe pad 200 can be made of metals or other high intensity materials. The track shoe pad 200 includes a notch 210, wherein the notch 210 includes one notch bottom 211 and two notch walls 212. The notch walls 212 and the notch bottom 211 are integrally connected, and the two notch walls 212 are opposite to each other.

[0032] The reinforcing unit 300 includes one base frame 310 and at least one supporting rib 330, in detail, the reinforcing unit 300 includes three supporting ribs 330 in the example of FIGS. 3-4B. The base frame 310 can be made of metals or other high intensity materials, and the base frame 310 includes one recessed portion 311 and two shoulder portions 320, wherein the recessed portion 311 is correspondingly connected to the notch bottom 211 of the track shoe pad 200. The two shoulder portions 320 and the recessed portion 311 are integrally connected and the two shoulder portions 320 are opposite to each other, and the two shoulder portions 320 are against the two notch walls 212, respectively. By the foregoing corresponding relationship, the reinforcing unit 300 can be embedded to the track shoe pad 200 so as to increase the stability of the combination of the reinforcing unit 300 and the track shoe pad 200. The supporting ribs 330 are disposed on one side of the base frame 310 which is located away from the track shoe pad 200 and are disposed among the recessed portion 311 and the two shoulder portions 320. The shape of supporting rib 330 can be a triangular prism, a rectangular prism, a semi-cylinder or a wave-shaped prism.

[0033] The elastic element 400 can be made of rubber or other elastic materials, and the elastic element 400 is detachably connected to the other side of the reinforcing unit 300 which is corresponding to the track shoe pad 200. The elastic element 400 can be connected to the reinforcing unit 300 during the founding solidification step of the elastic element 400. The protection of the reinforcing unit 300 can prevent sands or stone chips entering the gap between the track shoe pad 200 and the elastic element 400 which may abrade the elastic element 400, and the stability of the combination between the elastic element 400 and the track shoe pad 200 will not be affected.

[0034] The notch bottom 211 of the track shoe pad 200 includes four first through holes 213, four second through holes 214 and four first connecting members 215, wherein the first connecting members 215 respectively corresponds to the second through holes 214 for connecting to the track chain of the caterpillar vehicle. In the example of FIGS. 3-4B, each of the first connecting members 215 is a screw stem. Moreover, the recessed portion 311 includes four third through holes 316 (shown in FIG. 4B), four fourth through holes 313, four second connecting members 312, and three supporting ribs 330, wherein each of the third through holes 316 respectively corresponds to the first through holes 213, each of the fourth through holes 313 respectively corresponds to the second through holes 214, each of the second connecting members 312 respectively corresponds to the third through holes 316, and the three supporting ribs 330 are arranged equidistantly among the recessed portion 311 and the two shoulder portions 320 respectively.

[0035] The elastic element 400 includes four first concave holes 410, four second concave holes 420 and three recessed troughs 430, and the recessed troughs 430 are for containing three supporting ribs 330, respectively. Each of the first concave holes 410 of the elastic element 400 respectively corresponds to the third through holes 316. When the reinforcing unit 300 is connected to the elastic element 400, each of the first concave holes 410 is for containing the second connecting member 312 correspondingly, and each of the second concave holes 420 is respectively corresponding to the fourth through holes 313. Moreover, when the track shoe pad 200, the reinforcing unit 300 and the elastic element 400 are connected together, each of the second concave holes 420 is for containing the first connecting members 215 respectively, and whereby the contacted surface of the reinforcing unit 300 with the elastic member 400 can be tightly fitted.

[0036] The embedding combination of the three recessed troughs 430 and the three supporting ribs 330 can reduce the lateral shake of the elastic element 400 during the processing of the caterpillar vehicle. Simultaneously, the three supporting ribs 330 can effectively reinforce the supporting ability against the fractures from different directions and thereby prevent the reinforcing unit 300 from deforming and damaging.

[0037] In the example of FIGS. 3-4B, the second connecting member 312 is a screw nut, which is welded to connect on the third through hole 316 of the recessed portion 311, so that the stability of the integral combination can be increased. In the corresponding relationship, the first through hole 213, the third through hole 316, the second connecting member 312 and the first concave hole 410 are corresponding to each other and are approximately coaxial; the second through hole 214, the first connecting member 215, fourth through hole 313 and the second concave hole 420 are corresponding to each other and are approximately coaxial. When the track shoe pad structure assembly 100 is connected to the track chain, the first connecting member 215 should be passed through the second through hole 214 of the track shoe pad 200 and the track chain sequentially, and then the first connecting member 215 is connected with a first screw nut 216 so as to connect the track shoe pad 200 and the track chain.
