no. 1 approach

[0040] First, a first embodiment will be described with reference to FIGS. 1 to 12 . As shown in FIG. 1 , FIG. 2 , FIG. 3 and FIG. 12 , the crawler belt 21 of the first embodiment forms an endless structure by alternately arranging a plurality of first modules 22A and second modules 22B and connecting them. In this case, the first assembly 22A has support shafts 27 at both ends thereof, and the second assembly 22B has shaft sleeves 30 at both ends thereof. The first assembly 22A and the second assembly 22B are connected by fitting the bushing 30 on the support shaft 27 .

[0041] In this case, if any one of the first module 22A and the second module 22B is an odd number, the closed-loop crawler belt 21 cannot be formed. Therefore, when the total number of first and second modules 22A, 22B is an odd number, at least one (in this embodiment, one) third module is arranged and connected between the first module 22A and the second module 22B at any position. The assembly 22C enab...

no. 2 approach

[0065] Next, a second embodiment of the present invention will be described focusing on parts different from the first embodiment.

[0066] Figure 13 and Figure 14 As shown, in the second embodiment, a reinforcing plate 60 is provided as a reinforcing mechanism, and the reinforcing plate 60 is fixed to the lower surface of the track shoe 26 of the third link belt 31 by the bolt 40 fixing the third link belt 31 .

[0067] Therefore, in the second embodiment, the opening-side end portion of the third fastener tape 31 can be reinforced by the reinforcing plate 60 .

Abstract

A crawler belt including a first assembly (22A) and a second assembly (22B). The first assembly (22A) has a pair of first links (25) parallel with each other, and a second assembly (22B) has a pair of second links (28) parallel with each other. The sleeves (30) at both ends of the second assembly (22B) are fitted onto the support shafts (27) at both ends of the first assembly (22A). When the total number of the assemblies is odd, a third assembly (22C) is interposed between the first and second assemblies (22A), (22B). The sleeves (30) of the second assembly (22B) are fitted onto the support shafts (27) of the third assembly (22C), and the sleeves (30) of the third assembly (22C) are fitted onto the support shafts (27) of the first assembly (22A). Consequently, even when the total number of the crawler belt assemblies is odd, the crawler belt can adopt a parallel link type.

Description

technical field [0001] The present invention relates to a crawler belt included in a crawler-type work machine. Background technique [0002] Usually, the crawler of a crawler-type working machine such as a bulldozer or a hydraulic excavator is constituted by connecting a plurality of crawler belt units in a ring shape. The crawler belt is wound between a driving wheel and an idler wheel arranged at a predetermined interval on a vehicle body frame of the crawler-type working machine. Each track unit is driven by meshing with the teeth of a drive wheel constituted by a sprocket, so that the track runs while being supported on the drag pulley and the track roller, which are positioned between the drive wheel and the idler wheel. supported on the body frame. [0003] As a crawler belt assembly of such a crawler belt, for example, Patent Document 1 is conventionally known. Figure 7 The structure shown is the same as the structure shown in FIGS. 1 to 3 of Patent Document 1. FI...
