종래의 탄성 크롤러는 좌우의 차륜 전동영역에 대응하여 각 구동러그의 내단 굴곡부가 있고, 또 원주방향으로 이웃하는 구동러그의 내단 굴곡부 사이에 방진러그의 양단부가 위치하여 있기 때문에, 내단 굴곡부, 방진러그가 없는 것에 비교하여 주행시에 유동 회전륜이 차륜 회전운동영역을 회전운동하는 것에 의해 발생하는 진동, 크롤러본체가 굴곡하는 것에 의해 발생하는 균열을 한층 더 방지하는 것이 가능하다.The conventional elastic crawler has inner end bends of the drive lugs corresponding to the left and right wheel transmission areas, and both ends of the antivibration lugs are located between the inner end bends of the driving lugs adjacent in the circumferential direction. Compared with the absence of the flaw, it is possible to further prevent the vibration caused by the rotational movement of the flow rotary wheel in the wheel rotational movement area and the cracking caused by the bending of the crawler body during travel.
그러나, 종래의 탄성 크롤러에서는 차륜 회전운동영역에 대응하여 구동러그의 내단 굴곡부와 방진러그가 있지만, 이 구동러그와 방진러그의 사이에는 원주방향으로 큰 간격이 있기 때문에, 충분히 진동, 균열의 발생을 방지하기가 어렵다는 문제가 있다.However, in the conventional elastic crawler, the inner end of the drive lug and the antivibration lug correspond to the wheel rotational movement area. However, since there is a large gap in the circumferential direction between the drive lug and the antivibration lug, the vibration and cracks are sufficiently generated. There is a problem that is difficult to prevent.
즉, 주행시에는 유동 회전륜이 차륜 회전운동하여 탄성 크롤러를 원주방향으로 안내한다. 그러나, 유동 회전륜이 차륜 회전운동영역을 회전운동할 때에 구동러그, 방진러그의 어느 부분에서는 유동 회전륜이 이들의 러그를 타고 올라 상승하고, 또 구동러그, 방진러그가 없는 간격 부분에서는 유동 회전륜이 역으로 가라앉아 하강한다. 이 때문에, 유동 회전륜은 평탄한 노면의 주행에서도 항상 상하운동을 빈번하게 반복하는 것으로 되거나, 진동의 발생을 충분히 방지할 수 없다는 문제가 있다.That is, during driving, the flow wheel rotates the wheel to guide the elastic crawler in the circumferential direction. However, when the moving wheel rotates in the wheel rotational movement area, the moving wheel rises and rides up the lug in some parts of the drive lug and the anti-vibration lug, and the flow is rotated in the space without the driving lug and the anti-vibration lug. The front wheel sinks into the station and descends. For this reason, there is a problem in that the flow rotating wheel repeatedly repeats the vertical movement frequently even on a flat road surface, or the vibration cannot be sufficiently prevented.
또, 탄성 크롤러는 구동륜, 종동륜에 감긴 상태로 원주방향으로 회전운동하므로, 구동러그와 방진러그 사이에 간격부분이 있으면, 이 간격부분으로부터 크롤러본체에 균열이 발생하기 쉽다는 문제도 있다.In addition, since the elastic crawler rotates in the circumferential direction while being wound around the drive wheel and the driven wheel, there is a problem that if a gap portion is present between the drive lug and the antivibration lug, cracks are likely to occur in the crawler body from this gap portion.
본 발명은 이와 같은 종래의 문제점에 조감하여, 진동, 균열의 발생을 효과적으로 방지할 수 있는 탄성 크롤러를 제공하는 것을 목적으로 한다.An object of the present invention is to provide an elastic crawler that can effectively prevent the occurrence of vibrations and cracks in view of such a conventional problem.

이와 같은 구성의 탄성크롤러(4)에서는 양단측이 원주방향으로 이웃하는 구동러그(15)에 접속하는 방진러그(16)를 차륜 회전운동영역(14a), (14b)에 대응하여 배치되고, 그 구동러그(15)와 방진러그(16)의 머리부(15C), (16C)까지의 높이를 대략 같게 하기 때문에, 유동 회전륜(5)의 회전운동륜체(9a), (9b)가 크롤러본체(10)의 차륜 회전운동영역(14a), (14b)을 회전운동할 때에도, 구동러그(15) 사이에서 유동 회전륜(5)이 상하방향으로 불안정하게 진동하는 것과 같은 것이 없어지고, 종래에 비교하여 주행시의 진동 발생을 효과적으로 방지할 수 있다.In the elastic crawler 4 having such a configuration, the anti-vibration lugs 16 which are connected to the driving lugs 15 adjacent to each other in the circumferential direction are disposed corresponding to the wheel rotational movement regions 14a and 14b. Since the heights to the heads 15C and 16C of the driving lug 15 and the anti-vibration lug 16 are approximately equal, the rotary wheels 9a and 9b of the flow wheel 5 are crawler bodies. Even when the wheel rotational movement regions 14a and 14b of the rotational direction 10 are rotated, there is no such thing as the flow rotation wheel 5 unstablely oscillating in the vertical direction between the drive lugs 15, and conventionally In comparison, it is possible to effectively prevent the generation of vibration during driving.
또, 구동러그(15)와 대략 같은 높이의 방진러그(16)의 양단을 원주방향으로 이웃하는 구동러그(15)에 접속하고 있으므로, 구동러그(15)와 방진러그(16) 사이에 큰 간격이 있는 종래에 비교하여 크롤러본체(10)의 균열의 발생을 미연에 방지할수 있는 이점이 있다.In addition, since both ends of the anti-vibration lug 16 having substantially the same height as the drive lug 15 are connected to the adjacent drive lugs 15 in the circumferential direction, a large distance between the drive lugs 15 and the anti-vibration lugs 16 is achieved. Compared with the conventional ones, there is an advantage of preventing the occurrence of cracking of the crawler body 10 in advance.
그리고, 좌우 2열의 러그열(12a), (12b)이 원주방향으로 1/2피치(반피치) 어긋나 있고, 그 한쪽 러그열(12a), (12b)의 구동러그(15)의 내단부(15A) 사이에 다른쪽 러그열(12b), (12a)의 구동러그(15) 내단부(15A)가 배치되는 한편, 좌우 러그열(12a), (12b)의 각 구동러그(15) 내단부(15A)끼리가 크롤러본체(10)의 폭방향으로 중첩되어 배치되므로, 각 구동러그(15)의 길이를 충분히 확보하는 것이 가능하고, 지면쪽에 대한 구동력을 충분히 확보하는 것이 가능하다.Then, the left and right two rows of lugs 12a and 12b are shifted 1/2 pitch (half pitch) in the circumferential direction, and the inner end portion of the driving lugs 15 of one of the lugs 12a and 12b is shifted. The inner end portions 15A of the driving lugs 15 of the other lug rows 12b and 12a are arranged between the inner lugs of the left and right lug rows 12a and 12b, while the inner end portions 15A of the other lug rows 12b and 12a are disposed. Since the 15As are arranged so as to overlap each other in the width direction of the crawler body 10, it is possible to sufficiently secure the length of each driving lug 15 and to sufficiently secure the driving force to the ground side.
또, 좌우 2열의 각 러그열(12a), (12b)의 원주방향으로 이웃하는 구동러그(15)를 방진러그(16)에 의해 원주방향으로 접속하여 있으므로, 각 구동러그(15) 사이에 흙, 눈 등이 구동러그(15)를 따라 폭방향의 외측으로 이동하는 것과 같은 것이 아니고, 좌우 2열의 각 러그열(12a), (12b)의 방진러그(16) 보다도 내측의 구동러그(15) 사이에 흙, 눈 등이 삽입될 수 있다. 이 때문에 구동러그(15)를 원주방향으로 접속되는 방진러그(16)가 없는 것에 비교하여 건조한 포장, 강설지 등을 주행할 때의 구동력을 다시 향상시키는 것이 가능하다.In addition, since the drive lugs 15 adjacent to each other in the circumferential direction of each of the lug rows 12a and 12b in the left and right two rows are connected in the circumferential direction by the anti-vibration lugs 16, dirt is formed between the drive lugs 15. The driving lugs 15 on the inner side of the vibration lugs 16 in each of the left and right two rows of lugs 12a and 12b are not the same as the eye or the like moving along the driving lugs 15 in the width direction. Soil, snow, etc. may be inserted in between. For this reason, compared with the absence of the antivibration lug 16 which connects the drive lug 15 to the circumferential direction, it is possible to improve the drive force at the time of running dry pavement, snowfall, etc. again.
