- surface (4) means the surface not in contact with the ground, that is, the opposite surface of the surface (2). do.
- outer of a rubber track means an outer part of a pair of rubber tracks installed in the device, and “inner” is defined as an inner part of a pair of rubber tracks located near each other. do.
- the main lugs formed so as to exert a traction force on the surface 2 of the rubber track of the present invention may be referred to as the first lug 10 and the second lug 20.
- the first lug 10 and the second lug 20 have substantially different shapes.
- the first lug 10 has a first groove 12 formed in the width direction
- the second lug 20 has a second groove 22 formed in the running direction.
- the respective lugs 10 and 20 may exhibit their functions independently.
- the first lug 10 is formed to have the first groove 12 in the width direction of the rubber track, thereby securing a basic traction force.
- the rubber track will be advantageously deformed to have a specific radius of curvature. It is assumed that it has flexibility to bend flexibly.
- the first lug 10 and the second lug 20 are formed asymmetrically, not symmetrically with each other, as can be seen more clearly in FIG. 3.
- the first lug 10 and the second lug 20 are formed asymmetrically, as shown, alternately arranged with respect to the engaging portion 38 or alternately arranged with respect to the driving direction as shown. You will understand what it means.
- first groove 12 of the first lug 10 is closed to the outside, that is, for example, when the outside is closed, it can be seen that the first lug 10 has a U-shape. .
- the surface area of the first lug 10 may be substantially secured.
- the second lug 20 formed on the other side of the first lug 10 is formed with the second groove 22 in the traveling direction as described above.
- the inner and outer positions of the first lug 10 and the second lug 20 are optional.
- the second lug 20 is molded outside.
- the second lug 20 is molded inside. Since the second groove 22 is formed in the driving direction in the second lug 20, the second groove 22 can be firmly supported against centrifugal force during rotation and can be prevented from sliding sideways on the slope.
- the second groove 22 is formed with a sufficient length in the running direction of the second groove 22 This is because it is molded in the open state in the front and rear.
- the first lug 10 and the second lug 20 may be referred to as a main lug, and the size of the contact surfaces 14 and 24 in contact with the ground when these main lugs travel is an area required for driving. It can be determined by calculating
- the main lugs 10 and 20 are repeatedly arranged at equal intervals in the driving direction, and a plurality of auxiliary lugs 30 are formed between the first lugs 10 and the second lugs 20, respectively. have.
- the auxiliary lug 30 is molded in the width direction, and is formed to be smaller and smaller than the first lug 10 or the second lug 20, but has the following functions.
- the auxiliary lug 30 may perform a function of assisting the traction force in the soft ground.
- the auxiliary lugs 30 are formed to be lower than those of the first lugs 10 and the second lugs 20 described above, in the soft ground such as wetlands, the auxiliary lugs 30 can be used as an auxiliary means for exerting traction while the rubber tracks no longer fall out. It can be said that it can have a function as.
- the auxiliary lug 30 can be said to be formed in a concave portion between the first lug 10 and the second lug 20 substantially.
- the auxiliary lug 30 is formed to extend outwardly from the catching portion 38 that receives the sprocket from the rubber track and transmits power to the rubber track.
- the auxiliary lug 30 also has a function of preventing exposure of the steel cord embedded in the rubber track between the main lugs 10 and 20.
- auxiliary lug 30 is formed to extend inward and outward with respect to the engaging portion 38, which can be said to have a function of substantially connecting the central portion and the outer portion of the rubber track, thereby rubber This can help to prevent the occurrence of edge cuts that can occur at the edge of the track.
- the side protrusion part 40 is formed to surround the side surfaces of the first rubber 10 and the second rubber 20.
- the lateral protrusion 40 extends from the surface 2 of the first rubber 10 and the second rubber 20 to pass through the side surface, and then extends to the rear surface 4 of the rubber track as shown in FIG. 2. Molded. Therefore, it can be seen that the lateral protrusion 40 is formed while wrapping up the rubber track surface 2 and the rear surface 4, and by this configuration, can substantially occur outside the end of the metal core 36. It is possible to prevent the occurrence of edge cuts.
- Such a side protrusion part 40 also has the function to exhibit sufficient traction force especially in a soft ground. That is, when the rubber track falls to some extent in the soft ground, the lateral protrusion 40 located on the side of the rubber track can exert a traction for driving, which substantially surrounds the entire rubber track side and protrudes. It can be said to be a function based on.
- the side protrusion part 40 is formed to protrude while covering the entire side of the rubber track as described above.
- the end portions of the side projections 40 are divided into two.
- the stepped portion 48 having a step difference continuously such as a step on both sides. It can be seen that such a step portion is formed to have a slope toward the outside, in particular.
- Such inclined staircase 48 may be said to remove foreign matter that may be deposited by driving to the outside. In some sense, it may be said to have a self-cleaning function.
- step portion 48 By the structure of the step portion 48 itself and the inclined structure, foreign matter accumulated in the step portion is different in thickness, this foreign matter deposited in different thickness is the step portion 48 of the rubber track bent in an arc shape It will be more easily escaped by external forces in the process.
- the end portion of the side protrusion 40 divided into a fork while extending to the rear surface of the rubber track 4 cooperates with the step portion 40 while the rubber track is bent, so that the foreign matter can easily fall off. It will be natural to be able to exert external force.
- the mountain and the valley may have the same function and effect. And even in such a case, it would be desirable to mold to reduce the thickness slightly toward both edges of the rubber track.
