る。 [Detailed Description of the Invention] Industrial Application Field This invention relates to a rubber crawler. BACKGROUND ART FIG. 4 is a side view showing a part of a conventional rubber crawler and wheels. In the figure, 1 is a conventional rubber crawler, and 2 is a wheel. Figure 5 shows
It is a view seen from A-A in FIG. 4. In the figure,
3 is a crawler body , 4 is a core metal, 5 is a base of the core metal 4, 6 is a protrusion for rolling of the core metal 4, 7 is a rolling surface of the protrusion 6, 8 is a rolling surface of the roller 2, 9 is the collar of the wheel 2. FIG. 6 is a plan view of the rubber crawler 1 taken along line BB in FIG. 5. Therefore, in the conventional rubber crawler 1, the base portions 5 of the core bars 4 are horizontally embedded in the crawler body 3 at regular intervals. Each of the core metals 4 is formed with a pair of right and left wheel rolling protrusions 6 that protrude inward from the inner peripheral surface of the crawler body 3. Problems to be solved by the invention The core metal 4 of the rubber crawler 1 is as shown in Fig. 6.
They are arranged at regular intervals of pitch P in the longitudinal direction of the crawler body 3. Therefore, there is a gap L where the rolling surface 7 of the protrusion 6 for the core bar 4 is not provided. Therefore, when the rolling wheels match the distance L while the vehicle is running, rattling accompanied by an impact occurs. This makes the driver feel uncomfortable while driving. In addition, as shown on the right side of Figure 4, if the rubber crawler is subjected to reverse sliding action when traveling over a convex part of the ground, etc.
In the interval L, the corner A of the rolling surface,
B received a large impact, and the rubber parts around it sometimes peeled off. The object of this invention is to solve the above-mentioned problems and provide a rubber crawler in which the rolling wheels do not rattle in the above-mentioned spaced portions. Means for Solving the Problems The means of this invention taken to solve the above problems are as follows: (a) The bases of the core metals are embedded at regular intervals in the endless strip-shaped crawler body , and each of the core metals is A pair of left and right protrusions projecting inward from the inner circumferential surface of the crawler body is provided, and the tops of the protrusions are formed to serve as rolling pressure surfaces for rolling wheels having flanges on the left and right end surfaces. ing. In the rubber crawler, rubber member protrusions having approximately the same length as the above-mentioned interval parts are placed at regular intervals on the outside in the width direction of each interval part where the above-mentioned protrusions are not arranged on the inner peripheral surface of the roller crawler body. C. The position and height of the contact pressure surface of the rubber member protrusion is configured such that it abuts against the outer circumferential surface of the collar of the roller during running. Operation A: Since the rubber member protrusion is provided to compensate for the gap where the protrusion for rolling the roller of the rubber crawler is not arranged, when the roller is rolling in the above-mentioned interval, the outer circumferential surface of the roller collar is The rubber member comes into contact with the protrusion. (b) According to the above item (a), the rolling wheels that are rolling while the vehicle is running have their rolling surfaces in contact with the rolling protrusions of the rubber crawler, or the outer circumferential surface of the collar of the rolling wheels is covered with the rubber crawler. It is in contact with the member protrusion. Therefore, the wheels no longer wobble at the above-mentioned interval while the vehicle is running. Embodiments Hereinafter, embodiments of this invention will be described in detail based on the drawings. FIG. 1 is a side view showing a rubber crawler 10 and a wheel 2 according to this invention. Second
The figure is a view taken along line CC in FIG. 1. In the figure, 11 is a rubber crawler 10 according to this invention.
12 is a rubber member protrusion provided on the crawler body 11, 13 is a core bar, and 14 is a core bar 13.
15 is a protrusion for rolling the wheel of the core metal 13, 1
6 is a rolling surface of the protrusion 15. Figure 3 shows the second
It is a top view of the rubber crawler 10 seen from DD of a figure. Next, the configuration of the rubber crawler 10 according to this invention will be described with reference to FIGS. 1 to 3. Rubber member protrusions 12 having a length M that is approximately the same as the spacing portion L are placed at regular intervals P and on the outside in the width direction of each of the spacing portions L where the rolling surface 16 of the protruding portion 15 for the rubber crawler 10 is not arranged. The rubber member protrusion 12 is provided so as to protrude from the inner circumferential surface of the crawler body 11, and the position and height of the contact pressure surface C of the rubber member protrusion 12 is set such that it abuts against the outer circumferential surface of the collar 9 of the rolling wheel 2 during running. Configured. Next, the functions of the rubber crawler 10 according to this invention will be described. Since the rubber member protrusion 12 is provided to compensate for the interval L where the rolling pressure surface 16 of the protrusion 15 for the rubber crawler 10 is not arranged, when the roller 2 rolls at the interval L, the roller 2
The outer peripheral surface of the collar portion 9 contacts the contact pressure surface C of the rubber member projection portion 12. As a result, when the rolling wheels 2 are rolling while the vehicle is running, the rolling surface 8 of the rolling wheels 2 is in contact with the rolling pressure surface 16 of the rolling wheel rolling protrusion 15 of the rubber crawler 10, or the collar of the rolling wheels 2 is The portion 9 is in contact with the rubber member protrusion 12. Therefore,
The wheel 2 no longer rattles at the distance L while the vehicle is running. Also, the rubber member protrusion 12
By providing this, the rubber crawler 10 does not roll backwards even when traveling on a convex part of the ground, etc.
Therefore, problems such as peeling of the rubber member are eliminated. Effects of the invention When a vehicle equipped with a rubber crawler according to the prior art runs, an impact occurs when the rolling wheels meet the gap where the rolling surface of the protrusion for the core metal of the rubber crawler is not arranged. Causes scorching. As a result, the driver feels uncomfortable while driving. Further, when the rubber crawler is subjected to a reverse sliding action, the corner portion of the rolling surface of the protrusion for the core metal receives a large impact in the above-mentioned spaced portion, and the rubber member may also peel off near the periphery. However, with the rubber crawler according to this invention,
While the vehicle is running, either the rolling surface of the wheel or the outer circumferential surface of the collar is in contact with the rolling surface of the core protrusion of the rubber crawler or the contact pressure surface of the rubber member protrusion. This also applies when the rubber crawler is subjected to a reverse sliding action. Therefore, in the rubber crawler according to this invention, there is no rattling of the rolling wheels against the rubber crawler, and the rubber crawler does not move backwards even when traveling on a convex part of the ground. Since problems such as peeling are eliminated and durability is improved, vibrations while the vehicle is running are reduced, the driver feels more comfortable while driving, and the durability of the rubber crawler is improved.
