ある。[Detailed description of the invention] This invention is a crawler track for tracked vehicles such as construction vehicles, which can be used for civil engineering work that requires a particularly large traction force, and which does not damage the road surface when driving on paved roads or soft ground. It is related to crawler tracks.

た。 As shown in Fig. 1, most of the crawler tracks 1 of conventional tracked vehicles such as construction vehicles are made of metal. The disadvantage is that the tracks damage the road surface, and the ride quality is poor due to the heavy weight, noise, and vibration. In order to prevent damage to the road surface, there is a method of laying down slabs one after another on a paved road, but this process requires a lot of effort and time, and it is practically impossible to drive tracked construction machinery over long distances. is impossible. As a countermeasure for this, the entire track is made of a band-shaped integral rubber, or the track is made of metal with rubber bonded directly to the surface by baking or other methods.
Proposals include a metal crawler track with a rubber-glued frame attached to the road surface via bolts, and a rubber track with reinforcing bands embedded in it. However, although these devices can be used for snowmobiles and the like whose main purpose is transportation, they cannot be used for construction machines whose main purpose is civil engineering work where large forces are loaded. For example, in the case of the above, if the rubber is deformed so much that sufficient traction force cannot be exerted, and if the protrusion on the tread wears off, or if the protrusion that engages with the sprocket is damaged, the entire crawler track may be damaged. It was necessary to replace it. When a large force is applied to an object, the rubber peels off due to the difference in the amount of deformation between the metal and the rubber. When doing civil engineering work, you can remove the rubber-bonded frame from the tracks and attach it when driving on paved roads. Not only is this extremely complicated and time-consuming, but the frame must be carried around at all times. However, when a large amount of traction is applied to the rubber, the rubber deforms significantly and the rubber and reinforcing band peel off.
本考案の目的は、上記の欠点を解決し、金属製
履帯と同程度のけん引力を有し、損傷、摩耗が少
なく耐久性があつて部分的な履板の交換が可能
で、土木作業および舗装路走行等がともに可能で
あり、かつ、軽量、乗心地良好な履帯を提供する
ことにある。 The purpose of this invention is to solve the above-mentioned drawbacks, to have a traction force comparable to that of metal tracks, to be durable with less damage and wear, and to allow partial track replacement, and to be suitable for civil engineering work. The object of the present invention is to provide a crawler track that is capable of running on paved roads, is lightweight, and has good ride comfort.

帯を構成する。 The features of this invention are that the shoes constituting the crawler track are integrally molded with a hard synthetic resin to have a trapezoidal cross-sectional shape, have reinforcing fibers inside, have an uneven surface, and are made of hard synthetic resin. A reinforcing band made of synthetic resin, which is softer than the track shoes and has a good affinity with reinforcing fibers, is used to provide strength and rigidity. In addition, by making the tread surface of the shoes wider than conventional metal shoes when driving on paved roads, it prevents a decrease in traction force and improves wear resistance, which is a drawback of the material. I tried to prevent damage. This track is attached to metal links and
A track is constructed by connecting these links one after another with pins.

よる乗り心地改善を計ることもできる。 This invention can be applied to the tracks of tracked vehicles that do not want to damage the road surface when performing civil engineering work that requires traction and traveling on soft ground such as paved roads or grass fields, and can also reduce the weight of the vehicle. It is also possible to improve ride comfort by reducing noise and vibration.
本考案の実施例を以下図面に従つて詳細に説明
する。 Embodiments of the present invention will be described in detail below with reference to the drawings.
本考案による履板は、第2図に示すように、一

どの補強繊維11を有する。 As shown in FIG. 2, the track shoes according to the present invention are generally integrally molded from hard synthetic resin and have a trapezoidal shape, with the short side 2 serving as the tread surface and the long side 3 serving as the link mounting surface. In order to ensure compressive strength and rigidity, this shape increases the compression load by increasing the dimension b of the tread surface, and increases the rigidity by increasing the height dimension h. The slope 4 is for producing traction force. Moreover, this track shoe has a reinforcing band 10 shown in FIG. 3 inside. As shown in FIG. 4, the reinforcing band 10 has reinforcing fibers 11 such as steel wires with high rigidity inside.

凹凸を設けてあるので完全に密着する。 Hard synthetic resin, which is the material for shoe shoes, generally has a disadvantage that it has poor affinity with reinforcing pieces such as metal and easily peels off. However, the reinforcing band 10 of the present invention is
Since the shoe is made of a softer synthetic resin that has good affinity with the hard synthetic resin of the shoe and also has good affinity with the reinforcing fibers 11, even if the shoe is subjected to external force, the reinforcing fibers and the reinforcing band will not be removed. , the reinforcing band and the shoe will not separate from each other. Furthermore, since the surface of the reinforcing band 10 is provided with irregularities, it is completely adhered to the reinforcing band 10.

十分な剛性を示す。 In addition, compared to conventional belt-shaped rubber tracks, this track has improved durability such as wear resistance and damage resistance due to the hard synthetic resin used for the track. , the shoe has a sufficient height h, the reinforcing band 10 inside the shoe body is made of a material that has good affinity with the shoe and reinforcing fibers, and has an uneven surface, and
Since the reinforcing fibers 11 are inside the reinforcing band, it can compensate for the peeling of the reinforcing fibers and lack of rigidity, which are the weak points of synthetic resin footwear, thereby preventing wear and damage.
Shows sufficient rigidity.
