弾性履帯へ転接する転輪の構造の改良に関するものであ
る。[Detailed Description of the Invention] This invention relates to an improvement in the structure of a rolling wheel that contacts an elastic crawler track used in a power agricultural machine such as a combine harvester.

従来のこの種の弾性履帯は、青竹にはラグが突出して背
面は駆動輪の歯先と噛合うよう凹凸状に形成されてむり
、その上伸性履帯の内部には補強のための芯金を埋設し
ているので、弾性履帯の長手方向に卦ける各部の剛性は
夫々異なっている。Conventional elastic crawlers of this type have protruding lugs on the green bamboo and an uneven back surface that meshes with the tips of the teeth of the drive wheel.Furthermore, the inside of the elastic crawler has a core metal for reinforcement. , the rigidity of each part in the longitudinal direction of the elastic crawler track is different.

このため走行の際に転輪と接して荷重を受ける部分の押

形量が犬きく、変形量の少い芯金上方部にも交互に転接
することになる転輪は走行時に上下方向に激しく振動す
るため、乗心地を悪化させるうえ、各部の弛緩と損耗を
増加させている実状である。For this reason, the amount of crushing deformation of the part that contacts the rolling wheels and receives the load during running varies in size, and this deformation is particularly large between the core metals, and even in the upper part of the core metal where the amount of deformation is small. The wheels that alternately roll into contact with each other vibrate violently in the vertical direction while the vehicle is running, which not only worsens ride comfort but also increases loosening and wear and tear of various parts.

きわめて少くなるように工夫したものである。Therefore, in this invention, the left and right wheels, which are to be in contact with the outer sides of the left and right elastic crawler tracks in which core metals are embedded at a fixed interval, are placed in one place.
The rollers on the other side are arranged in a staggered manner, with the rollers 5 on the other side being shifted by the above-mentioned arrangement interval, and the rollers on the other side are placed on each core bar at the ground contact position. The construction is such that the wheels of the two are in contact with each other, and either the left or right wheel is always placed on top of all the core metals that are in contact with the ground. This system was devised to minimize the vertical movement of powered agricultural machinery when it travels.

状に配設し軸支している。The specific structure will be explained based on the illustrated embodiment. As shown in FIG. The lower frame is buried at regular intervals P in the longitudinal direction of the elastic crawler track 2, and is arranged so as to be in continuous contact with the back surface of the elastic track 1 above the left and right side portions 1a and 1b of the core metal 1. Rolling wheels 4a, 4b, which are disposed in the longitudinal direction on 3a, 3b, are supported by their shafts.
5a, 5b... are assumed, and the respective rolling wheels 4a..., 5a... are maintained at an interval of 1± of the buried interval P of the core bar 1... Therefore, the rolling wheels 4a, which are pivotally supported by one lower frame 3a, are the rolling wheels 5a, which are pivotally supported by the other lower frame 3b.
In this case, the shafts are shifted in the longitudinal direction by the distance P described above, and each core bar 1 is in the ground contact position, so that either the left or right wheel is always in rolling contact with the elastic crawler track 2. These wheels 4a, 4b, 5a, 5b, . . . are arranged in a staggered manner and are pivotally supported.

を維持できることになる。Since the wheel according to this invention is constructed as described above, either the right or left wheel is always placed on top of all the core metals 1 buried in the elastic crawler track 2 and in the ground contact position. Therefore, the machine frame 12 of the power agricultural machine supported via these wheels 4a, 5a, . . . can always maintain approximately the same height above the ground.

The wheel according to this invention has excellent effects.
