【考案の詳細な説明】
この考案は装軌車輌に装置する履帯（トラツ
ク）に係り、特にこの履帯の走行面に設けるゴム
パツドに関する。[Detailed Description of the Invention] This invention relates to a track installed on a tracked vehicle, and particularly to a rubber pad provided on the running surface of the track.
金属製の履板（トラツク・シユー）を互に枢軸
又はエンドコネクターで無端状に連結して構成し
た金属製履帯では、各履板の接地面に設けられた
グローサにより走行中舗装路面を著しく損傷する
ため、履帯の接地部にゴムパツドを装着するのが
普通である。 Metal tracks are constructed by connecting metal track shoes endlessly with each other via pivots or end connectors, and the grouser installed on the ground contact surface of each track shoe causes significant damage to the paved road surface during running. Therefore, it is common to attach rubber pads to the ground contact part of the tracks.

かつた。 In order to improve the durability of conventional crawler track pads, various studies have been made, including adding highly reinforcing fillers such as carbon black and silica to the rubber. However, since the rubber pads themselves are used under very harsh conditions, they are easily worn out and are subject to severe damage due to cutting and chipping.
このような従来の欠点を解消するために、最近

単体での欠点をゴム複合材によつて改善しようと
するものである。 In order to overcome these conventional drawbacks, a few ideas have been proposed recently. One of these is a structure in which a breaker made of a single layer or multiple layers of natural or synthetic fibers is embedded in a mesh-like fabric inside a rubber pad by integral molding (Utility Model Application No. 176881/1981); has a two-layer structure consisting of a tread part and a base part, the tread part is made of a more wear-resistant elastic material than the base part, the base part is made of a low heat generation elastic material, and the pad body is spaced apart from each other, In addition, inorganic or organic short fibers are uniformly dispersed inside the rubber pad body, and the orientation direction of the short fibers is adjusted to the direction of the composite. A configuration that intersects the friction surface at an angle of 20 to 160 degrees (Unexamined Japanese Patent Publication No.
51-102081) etc. All of these are attempts to improve the drawbacks of rubber alone by using rubber composite materials.
しかしながら、上記のようなゴム複合材を用い

じ、このため使用期間中にわたつて補強体がその
機能を充分に発揮できないという不具合が起る。 However, as a result of studying methods using rubber composite materials as described above, it was found that a completely satisfactory solution could not necessarily be obtained. That is,
In the method of reinforcing rubber pads with mesh fabrics or cords, the modulus of rubber and fibers is 10 2 to 10 3 Kg/
There is a difference of about mm 2 , and the rubber pad is subjected to a considerable load, causing large deformation and distortion, so the rubber and reinforcing body often separate, and the cord or mesh fabric is inserted into the pad. Because it is buried, heat generation during running can be reduced to some extent, and the reinforcing body can bear the load, but part of the reinforcing body may be cut off due to friction caused by the movement of the pad body while running. As a result, a problem arises in that the reinforcing body cannot fully perform its function over the period of use.
また、ゴムパツド中に短繊維を混合し、短繊維
の配向方向を摩擦面（接地面）に対し、略直角方
向としたのは、耐久性の向上はみられるが、実車
走行試験によつて、繊維の方向性により欠点があ
ることが判明した。 In addition, by mixing short fibers in the rubber pad and oriented the short fibers in a direction approximately perpendicular to the friction surface (contact surface), durability can be improved, but actual vehicle running tests have shown that It has been found that there are drawbacks due to the orientation of the fibers.

つたところ、短繊維の配向方向により、それぞれ
特徴のある破損状態を示した。 That is, as shown in Fig. 1, the pad body 2 of the track pad 1 is formed of a rubber composite material mixed with nylon short fibers, and the orientation direction of the nylon short fibers is (A) the same direction as the traveling direction S of the tracked vehicle. (B) Direction Y perpendicular to the traveling direction S in the horizontal plane; (C) Direction Z perpendicular to the ground contact surface (perpendicular); and actual vehicle running tests were conducted. However, depending on the direction in which the short fibers were oriented, each sample exhibited a characteristic failure state.

方向により、欠点のあることが判明した。 In case (A), the damage due to wear is severe, but the damage due to cutting and chipping at the front and rear of the ground contact surface is relatively less than that at the side surfaces. In case (B), contrary to case (A), there is relatively little damage on the side. Further, in case (C), there is little damage due to wear, but there is a lot of damage due to cutting or chipping at the peripheral edge of the pad body 2 (damage increases in the order of rear, side, and front portions of the ground contact surface).
The test results revealed that there were defects depending on the orientation direction, including the case where the short fibers were oriented in a direction substantially perpendicular to the ground surface of the pad body.

供することを目的とする。 Taking the above test results into consideration, this idea involves improving the track pad by eliminating the orientation effect while retaining the effectiveness of fiber as a reinforcing material. The purpose of the present invention is to provide a crawler track pad which has a long running life and has a significantly extended running life.

とを特徴とするものである。 For this reason, this invention uses a rubber composite body in which 0.5 to 30.0 volume percent of short fibers of organic fibers, inorganic fibers, or metal fibers with a length of 2 to 6 mm are mixed in a rubber elastic body made of natural or synthetic rubber. The rubber composite material includes at least a rubber composite material in which the short fibers are oriented in a direction substantially perpendicular to the ground plane, and a rubber composite material in which the short fibers are oriented in the same direction as the traveling direction. The above combination can be achieved by providing a rubber composite material in which short fibers are oriented in the same direction as the traveling direction at the front of the crawler pad in the traveling direction, or by providing the two materials in the longitudinal direction of the crawler pad. It is characterized by the fact that the rubber composite materials are provided alternately.

Furthermore, reinforcing agents, fillers, softeners, vulcanizing agents, vulcanization accelerators, etc., which are commonly used in rubber elastic bodies, are used as compounding agents.

によつてさらに完全な接着が得られる。 In order for the short fibers used as the reinforcing material to sufficiently withstand the large deformation strain that the rubber composite material receives, it is preferable that the interface thereof, that is, the rubber and the fibers have sufficient adhesion. To this end, so-called HRH adhesive formulations are used in which, for example, resorcinol, hexamethylenetetramine (or hexamethoxymethylmelamine) and finely powdered silica are added to the rubber compound, and RF is generated during vulcanization to bond directly to the fibers. These HRH treatments and
It is recommended to use RFL treatment in combination. Adhesion using silane and titanium coupling agents and commercially available adhesives is also possible. For example, in the case of nylon fibers, strong adhesion can be obtained with either the HRH treatment or the RFL treatment, but more perfect adhesion can be obtained by using the two treatments together.

-10 mm, preferably 2-6 mm. If the cut length of the fiber is too short, the expected physical properties of a rubber composite material cannot be obtained, and on the other hand, if the cut length is too long, not only will the rubber kneading process be difficult;
Cutting occurs during the kneading process, resulting in shortening. Further, even if the fibers can be kneaded in a somewhat long state, the distortion caused by large deformation will have an adverse effect on improving the pad properties.
