In a first example, the reinforcement 12 and the track sole 14 can be attached to the track body. 16 via known means, such as via nuts and bolts, or via adhesives. Such a track segment 10 can be used with tracked vehicles, for example military tanks or military combat vehicles, such as those deployed in hot climates, for example the desert, or desert-like environments.
    The crawler body 16 may be metallic, as is known in the art, and includes openings 20, generally indicated as binoculars, which. are used for mounting the track segments 10 on pins 22 to form the track used on tracked vehicles. Fur rubber (not shown) is generally arranged around the portion of the pin 22 which is received in the binoculars 20,
    In use, the reinforcement 12 is subjected to repeated cyclic loads as each track roller (not shown) of the track vehicle traverses the track segment 10, and the track shoes 14 contact the ground. To reduce or prevent deterioration of the reinforcement 12, and to provide a desirable balance of low heat buildup under repeated highly dynamic cyclic compression conditions, desirable load bearing capability, high heat resistance, and good notch resistance. at tearing in hot climates, the reinforcement 12 is formed from an EP (D) M rubber-based compound, as described below. In addition, each roller is generally provided with rubber around it, which comes into contact with the reinforcement, so that the rubber of the roller and the crawler sole 14 can be formed generally from the compound based on EP (D) M rubber, but may also be formed from other suitable rubber compounds known in the art.

Such additives may be used in customary amounts.
    In one embodiment, the EP (D) M rubber reinforcing compound comprises a rubber compound having 100 phr of EP (D) M rubber, wherein the diene component is optionally present, about 3 to about 9 phr organic peroxide, and about 5 to about 30 phr of one or more acrylic and / or methacrylic co-agents, for example, zinc diacrylate, zinc dimethacrylate, or an acrylic ester. In a first example, the EP (D) M rubber is an EPDM.
    The mixture of the rubber compound can be accomplished by methods known to those skilled in the art. For example, the ingredients are typically blended in at least two steps, i.e., at least one non-productive step followed by a productive blending step. Final curative agents are typically mixed in the final step, which is usually referred to as the "productive" mixing step, wherein the mixing typically occurs at a temperature, or ultimate temperature, below the vulcanization temperature of the product. elastomer. The terms "non-productive" and "productive" mixing steps are well known to those skilled in the art of rubber blending. The EP (D) M rubber-based compound can finally be shaped and cured using a normal curing cycle, so as to form the reinforcement.
    Non-limiting examples of an EP (D) M rubber compound as described are now described below. These examples are merely for the purpose of illustration and should not be construed as limiting the scope of the present invention or how it may be practiced. Other examples will be appreciated by those skilled in the art.
    Tables IA and IB: Test samples 1 to 20,

    In preparing each of the EPDM rubber compounds, the nonproductive stage components were added to a Banbury mixer. These components were mixed for about 4 to 5 minutes until a temperature of about 160 ° C was reached. Productive stage components were added and mixed together for about one minute and thirty seconds until a temperature of about 100 ° C was reached. Then, the raw material was passed through the mill and allowed to cool.
    A control test sample was prepared in a similar manner. The control sample was a standard sulfur-cured SBR-based compound comprising 100 phr of SBR, and usual sulfur and additives in customary amounts.
    Each of the EPDM rubber compounds and the SBR control sample were characterized using, for example, ASTM standard test procedures or variations thereof as shown in Tables 2A (Examples 1-10) and 2B. (Examples 11-20 and SBR control samples) below. The results are also shown in these tables, and further described below.





    With respect to the modulus / traction / elongation test, generally, higher modulus, tensile and elongation values tend to indicate a desirable stiffness in tension and compression for the rubber compound. These properties, when considered with respect to the SBR control sample, however, need to be balanced with the other properties. With the aging / tension / elongation modulus test after aging, in general, the least amount of change from the origin is the best. All of the EPDM samples indicate less change on thermal aging compared to the SBR control sample.
    With respect to the strain test under a load, a higher percent pound-per-foot deformation tends to indicate a desirable load bearing capacity of the rubber compound. Again, these properties, when considered relative to the SBR control sample, also need to be balanced with the other properties. Based on the test results, the EPDM samples appear to generally operate at least as well or better than the SBR control sample.
    Compared to the determination of the heat-storage characteristics, minimizing the temperature increase of the sample is desirable, which translates to lower temperatures for the fur rubber. A sample with a low delta tan is also desirable. In addition, a low setting percentage or low compression values tend to indicate desirable creep resistance. In addition, the sample needs to survive cyclic dynamic compressions without failure. Thus, a sample that breaks during a test or sample that forms porosity and / or internal cavities due to elevated temperature increases is undesirable. Regarding the creep test, this is another measure of the resistance of the sample to changes due to heat. Based on the test results, all EPDM test samples showed a significant improvement compared to the SBR control sample.
    With respect to the aging wear and tear resistance test, higher numbers tend to indicate desirable tearing properties. Based on the test results for the post-aging tear test, all of the EPDM samples showed less change compared to the SBR control. Compared to the hardening test, for a treatment, a low torque with a safe curing time is desirable. However, this property is primarily for factory treatment as compared to on-site performance.
    Overall, the EPDM 7 test sample appears to provide the most desirable characteristics compared to the SBR control sample. However, other EPDM rubber compounds (such as EPM) are provided for use as reinforcements in crawler segments for tracked vehicles in hot climates. Such EP (D) M rubber reinforcements can provide a desirable balance of low heat build up under heavy dynamic cyclic compression conditions, and also have a desirable load carrying capacity, high heat resistance, and good heat resistance. notch / tear resistance in hot climates.
