2. Description of the Related Art As shown in FIG. 10, in a rubber crawler conventionally used for a construction vehicle, an agricultural vehicle, or a leisure vehicle, a core bar is usually used as a lightweight rubber crawler. The pair of rubber protrusions 2 and 2 integrally formed with the rubber crawler 1 without being embedded is driven by the drive pin 7 of the pin drive type sprocket 6. In such a structure, the recess 3 between the pair of rubber projections 2 and 2 is substantially flush with the inner peripheral surface of the rubber crawler 1, and the drive sprocket 6 or a rolling wheel (not shown) or the like rolls in the recess 3. However, in order to effectively prevent the drive sprocket 6 and the rolling wheels from being disengaged during rolling, the height of the rubber projections 2 is sufficiently high from the inner peripheral surface of the rubber crawler 1. Although it has to be formed, this results in the tip of the rubber protrusion 2 being easily bent. That is, the lateral rigidity of the rubber protrusion is likely to be insufficient. This tendency becomes particularly noticeable when traveling on a slope or in steering, and in the worst case, the drive sprocket 6 and the wheels are derailed. In addition, this tendency will be compounded by an increase in the load weight. In order to increase the lateral rigidity of the rubber protrusions 2, the height of the rubber protrusions 2 may be lowered, but as a result, the drive sprocket 6 and the wheel derailment will again occur. In other words, although the heights of the rubber protrusions 2 have opposite characteristics, the result is an unfavorable situation of derailment. Further, as shown by hatching in FIG. 10 (A), the area of the portion where the rubber protrusion 2 of the rubber crawler 1 is slidably contacted by the drive pin 7 of the drive sprocket 6 is driven only by the front surface or the rear surface of the rubber protrusion 2. Since the rubber protrusions 2 themselves must bear the high surface pressure due to the force, it is not only disadvantageous in increasing the wear resistance of the rubber protrusions 2, but also the rubber crawler 1 which is running depending on the road surface condition. Are driven in an oblique direction, the pair of rubber protrusions 2 and 2 are individually subjected to an unbalanced load and are inferior in complementarity to each other as a pair of rubber protrusions. there were.

As described above, since the rubber projections are formed at a sufficient height from the inner peripheral surface of the rubber crawler to prevent derailment, the lateral rigidity of the rubber projections is insufficient, and the drive sprocket and the rolling contact are prevented. In order to roll the wheel, the recess between the pair of rubber protrusions is made almost flush with the inner peripheral surface of the rubber crawler, which deteriorates the wear resistance and deteriorates the complementarity of the rubber protrusions. The conventional rubber crawler has many problems to be solved. In order to solve the above problems of the prior art, the present invention has the contradictory characteristic that the lateral rigidity can be increased while the rubber protrusion has a sufficient height, and when traveling on a slope or in steering. Another object of the present invention is to provide a rubber crawler which does not cause derailment due to an increase in loaded weight and the like, and which is excellent in mutual complementarity as a pair of rubber projections and excellent in abrasion resistance.

In this example, the pair of rubber protrusions 2 and 2 are connected to each other as if they were a lower part, and the upper part is cut away to form a concave part 3 to form a bulging part 4. is there. Reference numeral 5 denotes a lug formed on the outer peripheral side ground contact surface of the rubber crawler 1. It should be noted that an appropriate reinforcing wire may be embedded in the rubber crawler 1 in the length direction. As shown in FIG. 2, the rubber crawler 1 formed in this way advances by driving the rubber protrusions 2 and 2 by the drive pin 7 of the sprocket 6 of the pin drive system. The area of the portion where the rubber protrusion 2 is driven and slidably contacted by the drive pin 7 is a hatched portion in FIG. 2 (A), and the drive pin is provided not only on the front surface of each rubber protrusion 2 but also on the front surface of the bulging portion 4. Responsible for driving surface pressure by 7. Thus, by forming the bulging portion 4 in the concave portion 3 between the pair of rubber protrusions 2 and 2,
The rubber protrusions 2 and 2 are firmly connected to each other by the bulging portion 4, and the lateral rigidity can be increased while the rubber protrusion 2 has a sufficient height. Therefore, wheel running does not occur even when the vehicle is running on a sloping ground, when steering, or when the loaded weight increases, and the rubber crawler 1 is driven to run diagonally depending on road surface conditions, and a pair of rubber protrusions are driven. Even if each of the two 2 and 2 independently receives an unbalanced load, the bulging portion 4 bears the load of the other party due to the driving force, and the pair of rubber protrusions are excellent in complementing each other. Engages with the drive pin 7 of the drive sprocket 6 to reduce the surface pressure due to the drive force, and the wear resistance performance can be greatly improved. Further, by forming the cross-sectional shape of the bulging portion 4 so as to match the tooth profile between the drive pins 7 and 7 of the drive sprocket 6, the bulging portion 4 between the drive pins 7 and 7 of the drive sprocket 6 is formed. And the drive sprocket 6 does not damage the bulging portion 4. Not only the swelling portion 4 can also bear a part of the driving force of the driving sprocket 6. Further, as shown in FIGS. 9 (A) and 9 (B), if driven by a drive sprocket in which disk-shaped discs 6 ′ and 6 ′ are arranged on both sides of the pair of rubber protrusions 2 and 2,
The rubber projections 2 are sufficiently high to add the effect of preventing wheel slippage, thus ensuring perfect operation.

Next, examples of the bulging portion 4 will be described below. In the structure shown in FIG. 3, the upper surface of the bulging portion 4 is substantially horizontal, and the complementarity between the rubber protrusions 2 and 2 is extremely high. 4 is slightly different from the embodiment shown in FIG. 1, the pair of rubber protrusions 2 and 2 are divided without being connected at the lower part, but when they rise from the inner peripheral surface of the rubber crawler 1. The bulging portion 4 is immediately formed. The bulging portion 4 of this example has a sine curve arcuate cross section and is suitable for forming a tooth profile on the drive sprocket 6. The one shown in FIG. 5 has a slightly thin bulging portion 4 and is excellent in discharging performance of mud that has entered between the rubber protrusions 2 and 2, but since the sharing of the driving force is slightly low, it is relatively small and lightweight. Suitable for type vehicles. In the structure shown in FIG. 6, the bulging portion 4 has a two-step chevron cross section, and by repeated engagement and disengagement between the teeth of the drive pins 7 and 7 of the drive sprocket 6, the contact and separation between the tops of these chevron shapes are repeated. The mud is effectively discharged. The one shown in FIG. 7 has a pair of rubber protrusions 2 and 2 ′ arranged in a zigzag pattern which are offset from each other in the lengthwise direction. In a side view, the pair of rubber protrusions 2 and 2 ′ overlap each other. By forming the bulging portion 4 in the concave portion 3, it is possible to improve the complementing performance of the zigzag rubber protrusions 2 and 2'which are originally inferior to each other in complementation. Figure 8
Unlike the above-described embodiment, the rubber projection 2 shown in FIG. 6 has a substantially trapezoidal shape in side view.
It effectively prevents lateral movement of the disk portion of the wheel and the rolling wheel to further enhance the derailment prevention effect.
