Description

Endless Drive Track with X Type Combine Band

The present invention relates to an endless driving track having a fastening band, and more particularly, a plurality of cores provided inside the endless driving track are continuously joined by a fastening band, and then molded with rubber to form a molding part. By the external load, the core can tear the molded part of the rubber material and maintain the state without being exposed to the outside.

In general, military equipment such as trams can protect roads, reduce vibrations and noise generated during driving, and reduce the load of the equipment itself in driving on unpaved roads and pavements, as shown in FIG. 1. In addition, an endless drive track 20 of a caterpillar type for traveling is provided under the tram 10.

The endless drive track 20 is rotated by the sprocket 11 provided on one side to allow the tank 10 to move smoothly through the plurality of driving wheels 12.

Looking at the structure of the infinite drive track 20 in detail, as shown in Figs. 2 and 3, the core 21 and a plurality of cores provided at intervals to maintain a predetermined strength while being made of steel 21 consists of a cord 22 which wraps around the core 21 to be able to withstand tension forces firmly.

In addition, a molding unit 23 for molding the core 21 and the cord 22 of the steel material to be integrally connected by molding the rubber material is formed.

In addition, the core 21 has a structure in which two protrusions 21a are formed at intervals, and a hole 24 or a groove is formed between the core 21 and the core 21. In FIG. 3, it is shown as a hole.

 In the conventional endless drive track 20 having such a configuration, the molded part 23 made of a soft rubber material is likely to be locally damaged when mounted on the tram 10.

Specifically, in the conventional infinite driving track 20, both side surfaces 21b of the core 21 provided inside the molding part 23 are vertically formed, and a sharp edge part is formed. Moreover, since the side surface of the said cord 22 is also formed in the perpendicular | vertical surface similarly, it forms a sharp edge part similarly to the core 21. As shown in FIG.

Furthermore, since both side surfaces 21b of the core 21 and the side surfaces 23a of the molding part 23 are filled with rubber only, if they collide with a sharp object in the lateral direction or an external impact is applied while driving, Since it is transmitted to both sides 21b of the core 21 as it is, the molding portion 23 of the rubber material is torn or cracks, and a portion of the infinite drive track 20 is separated seriously, the entire infinite drive track 20 There was a problem that needs to be replaced.

 In addition, when the tank 10 is subjected to an impact in the up and down direction while driving, the cores 21 try to shift upward and downward. In this case, a means for supporting a separate core 21 is formed in the molding part 23. Since it is not provided and is maintained only by the molding part 23, the arrangement state is deformed, and the molding part 23 may be torn and exposed to the outside, or a crack may be generated locally, thereby requiring the replacement of the infinite driving track.

Accordingly, the present invention has been invented to solve the above conventional problems, the core provided inside the infinite driving track due to the external impact in the up and down direction during the running of the tank, tearing the molding part forming the infinite driving track This is to prevent the exposure to the outside.

The present invention is an infinite drive track consisting of a core provided with a plurality of intervals to maintain the strength therein, a cord to withstand the tensile force while wrapping the core, and a molding part for molding the core and the cord to be integrally connected To

The coupling bands are continuously coupled to both side surfaces of the core so that the cores are coupled to each other and the cores are provided in the molding part to maintain the arrangement state in the molding part.

The fastening band may be configured in an X shape.

Both sides of the core has a structure in which the coupling groove is formed so that the fastening band is securely coupled.

As described above, the present invention is molded by rubber in the state where cores embedded in the endless drive track are fastened by a fastening band in advance, so that the tram having the endless drive track in the up and down directions may occur when driving on an unpaved road. By the load, the core inside the molding part may be prevented from tearing the molding part and being exposed to the outside.
