Description

technical field

[0001] The invention relates to a novel structure of a rubber track, in particular to a rubber track mainly used for running on wet ground. Background technique

[0002] In a rubber crawler track suitable for running on wet ground, core members are buried at fixed intervals along the length direction of the annular rubber elastic body, steel cords are wound on the outside of the core member, teeth are formed on the outside of the rubber elastic body, and teeth are formed on the outside of the core member. Engaging holes are formed through the inside and outside of the rubber elastic, which are engaged with the drive sprocket.

[0003] Figure 8 It is a top view of the inner peripheral side of the rubber track that has been widely used. Figure 9 It is the top view of the peripheral side Figure 10 is along Figure 8 The cross-sectional view taken along the line B-B in the center. 1 is a rubber elastomer, in Figure 8 The center is continuous up and down th...
