れている。１１は張力保持用のコード層である。 In Fig. 6 and Fig. 7, 1 is an endless belt made of an elastic material such as rubber.
Horizontal reinforcing members 3 each having a pair of projections 2 are embedded at equal intervals, and engagement holes 4 are formed between each horizontal reinforcing member 3 in the center in the width direction.
Main lugs 6, vertical lugs 7, and auxiliary lugs 8 are provided at equal intervals on the ground contact surface 5 side of the outer circumference of the endless belt 1. There are a pair of main lugs 6 on the left and right, and they are arranged in a V-shape so that the rear side opposite the running direction of the endless belt 1 (indicated by arrow a) is flared toward the end, and the middle part of the lugs passes through part of the projected area of the horizontal reinforcement 3. The vertical lugs 7 are provided on the inner end side of each main lug 6,
The vertical lug 7 extends forward in the running direction (indicated by arrow a) so as to move away from the horizontal reinforcement 3, and is disposed within the projected area of a wheel passing plane 10 through which the straddling wheel 9 passes. The auxiliary lug 8 is disposed approximately within the projected area of the horizontal reinforcement 3 between the pair of left and right main lugs 6. Reference numeral 11 denotes a cord layer for maintaining tension.

跨ぎ転輪９が転輪駆動面１０上を相対的に転動す
る。 This endless belt 1 is hung around a driving wheel and a driven wheel, and when running, the protrusion of the driving wheel engages with the engagement hole 4 and rotates in the direction of arrow a by the driving force of the driving wheel. . At this time, the straddle wheel 9 arranged between the drive wheel and the driven wheel relatively rolls on the wheel drive surface 10.
（考案が解決しようとする問題点）
従来、主ラグ６は後方に移るに従つて次第に低
くなるが、或いは横置補強体３の投影域に対応す
る部分が一段低くなるように構成されており、ま
た横置補強体３の投影域にある補助ラグ８は主ラ
グ６よりも低くなるように構成されていた。(Problem to be solved by the invention) Conventionally, the main lug 6 has been configured so that it becomes gradually lower as it moves toward the rear, or the part corresponding to the projection area of the horizontal reinforcement body 3 becomes lower. Further, the auxiliary lug 8 in the projection area of the horizontal reinforcement body 3 was configured to be lower than the main lug 6.
従つて、横置補強体３の投影域では主ラグ６及
び補助ラグ８部分の全体としての剛性が上がる
が、高低差をつけることによつて走行時の振動の
発生を抑制し軽減することができる。 Therefore, although the overall rigidity of the main lug 6 and auxiliary lug 8 portions increases in the projection area of the horizontal reinforcement body 3, it is possible to suppress and reduce the occurrence of vibrations during running by creating a height difference. can.
しかし、従来、縦ラグ７は、回走方向の前後と
も同一高さで同一幅であるため、縦ラグ７自体の
剛性はｂの範囲で均一であるが、実際に転輪９が
通過した際の見掛上の剛性が変化し、これが振動
発生の原因となつていた。 However, conventionally, since the vertical lug 7 has the same height and the same width both in the front and back in the running direction, the rigidity of the vertical lug 7 itself is uniform within the range b, but when the rolling wheel 9 actually passes The apparent rigidity of the material changes, which causes vibration.
即ち、縦ラグ７は横置補強体３に対して遠近方

しての剛性が変化する。そのため縦ラグ７の前端
側では転輪９の沈込みが生じ、転輪９が上下動す
ることによつて振動が発生する欠点があつた。 In other words, since the vertical lug 7 is located in the distance direction with respect to the horizontal reinforcement body 3, when the rolling wheels 9 pass, the overall rigidity is small at the front end side away from the horizontal reinforcement body 3, and the horizontal reinforcement body 3, the overall stiffness increases, and even within the range b, the overall stiffness changes before and after. As a result, the rolling wheels 9 sink on the front end side of the vertical lugs 7, and as the rolling wheels 9 move up and down, vibrations are generated.

る。(Means for solving the problem) In the present invention, as a specific means for that purpose, horizontal reinforcing bodies 3 are embedded at equal intervals in the endless band 1 made of an elastic material, and the endless band 1 is An engagement hole 4 is formed at the center in the width direction between each of the horizontal reinforcing bodies 3, and the middle part passes through the projection area of the horizontal reinforcing body 3 on the ground plane 5 side of the endless band 1. A pair of V-shaped main lugs 6 are provided at equal intervals, and the rear side in the running direction of the main lug 6 widens toward the end. In a crawler equipped with a vertical lug 7 extending forward in the direction, the vertical lug 7 formed within the projected area of the wheel passing surface 10 through which the straddle wheel 9 passes is wider on the front end side in the turning direction than on the rear end side in the turning direction. In addition, the width becomes gradually narrower toward the rear end in the running direction.

一になる。(Function) The width W 1 of the vertical lug 7 on the front end side is larger than the width W 2 on the rear end side approaching the horizontal reinforcing body 3, and the width gradually becomes narrower as it moves toward the rear end side. Coupled with the presence of the horizontal reinforcing body 3, the overall rigidity of the vertical lug 7 portion when the rolling wheels 9 pass is approximately uniform both in the front and rear.

以下、図示の実施例について本考案を詳述す

て左右両側から幅狭に構成されている。(Example) The present invention will be described in detail below with reference to the illustrated embodiment. Components with the same names as those in the conventional example shown in FIGS. 6 and 7 are designated by the same reference numerals, and description thereof will be omitted. As shown in FIGS. 1 to 3, vertical lugs 7 are provided that extend forward in the running direction (arrow a) from the inner ends of the pair of left and right main lugs 6.
The width W 1 on the front end side in the running direction is larger than the width W 2 on the rear end side, and the width becomes narrower from both left and right sides as it moves from the front end side to the rear end side.
この縦ラグ７は前後方向の全範囲にわたつて同
一の高さH1を有し、この縦ラグ７の高さH1が最
大であつて、主ラグ６の高さH2、補助ラグ８の
高さH3が順次僅かづつ低くなるように決められ
ている。 This vertical lug 7 has the same height H 1 over the entire range in the front-rear direction, and the height H 1 of this vertical lug 7 is the maximum, and the height H 2 of the main lug 6 and the auxiliary lug 8 The height H3 is determined to decrease gradually.
このように縦ラグ７の幅を決めれば、縦ラグ７

範囲ｂにわたつて略均一化できるため、縦ラグ７
の前端側での転輪９の沈込みがなくなり、振動の
大幅な低減を図ることができる。 If the width of the vertical lug 7 is determined in this way, the vertical lug 7
Even if the same elastic material is used, the rigidity of the vertical lug 7 itself is high on the front end side, and the rigidity decreases as it approaches the horizontal reinforcement body 3 side. Therefore, in addition to improving the overall rigidity in the vicinity of the horizontal reinforcement 3, the overall rigidity when the longitudinal lug 7 portion of the rolling wheel 9 passes is increased by increasing the overall stiffness in the longitudinal direction of the longitudinal lug 7. Because it can be made almost uniform over range b, the vertical lag 7
This eliminates the sinking of the rolling wheels 9 on the front end side, making it possible to significantly reduce vibration.
この振動低減は、ラグ高さとも関係するため、
縦ラグ７の高さH1を最大とし、主ラグ６、補助
ラグ８と順次低くすることによつて接地時の全体
的な剛性が略等しくなり、更に振動低減効果が上
がる。 This vibration reduction is also related to the lug height, so
By setting the height H 1 of the vertical lug 7 to the maximum and decreasing the height H 1 of the main lug 6 and the auxiliary lug 8 in sequence, the overall rigidity at the time of contact with the ground becomes approximately equal, and the vibration reduction effect is further improved.
縦ラグ７は、第１図に示すように後方に移るに
従つて左右両側から幅狭に形成する他、第４図、
第５図に示すように非対称に形成しても良い。 As shown in FIG. 1, the vertical lugs 7 are formed to become narrower from both left and right sides as they move toward the rear.
It may also be formed asymmetrically as shown in FIG.
