(イ) 産業上の利用分野
本考案は、コンバインや運搬車や自走自脱等の
走行装置として用いられる履帯式自走車の転輪軸
受支持装置に関するものである。[Detailed description of the invention] (a) Industrial application field The present invention relates to a roller bearing support device for a track-type self-propelled vehicle used as a traveling device such as a combine harvester, a transport vehicle, or a self-propelled self-propelled vehicle. .
(ロ) 従来技術
先願の技術として、履帯式自走車の転輪を左右

る。(b) Prior Art As a prior art, a technology has been filed that allows the wheels of a tracked self-propelled vehicle to rotate left and right.
例えば実願昭56−190877号の如くである。 For example, Utility Application No. 56-190877.
(ハ) 考案が解決しようとする問題点
機体が平坦な地面を進む際には、転輪は左右の
履帯の複列づつ、計4列が全てそれぞれの履帯の
上に接地して進むので不具合いが生じないのであ
るが、第5図に示す如く、一方の履帯が接地する
面と、他方の履帯の接地する面の角度が異なる時
には、左右の複列転輪のうちの外側の転輪列のみ
しか接地せず、内外の転輪と履帯の間が開いてし
まうのである。(c) Problems that the invention aims to solve When the aircraft moves on flat ground, all four rows of track wheels, each with double rows of left and right tracks, touch the ground on each track, which is a problem. However, as shown in Fig. 5, when the angle of the surface where one crawler makes contact with the ground is different from the surface where the other track makes contact with the ground, the outer track of the left and right double-row track wheels Only the rows touch the ground, leaving a gap between the inner and outer wheels and the crawler track.
これにより転輪と履帯の間が開いて履帯が外れ
やすくなり、又、転輪のうちの一列のみ、それも
外端部のみで機体重量を受けてしまうので転輪や
履帯の偏摩耗が生ずるのである。 This opens up the space between the wheels and the track, making it easy for the tracks to come off.Also, only one row of wheels, and only the outer end, receives the weight of the aircraft, causing uneven wear on the wheels and tracks. It is.
以上の欠点を解消すべく、本考案は左右の複列
転輪のうちの一列ずつの転輪軸軸受ケースを前後
方向の回動軸で支持し、地表面の傾斜に沿つて傾
動可能としたものである。 In order to solve the above-mentioned drawbacks, the present invention supports the bearing case of each row of the left and right double-row wheels with a rotating shaft in the front and back direction, making it possible to tilt along the slope of the ground surface. It is.
該構成により、履帯が車体に対して或る角度を
持つて脱輪しようとした時に、転輪がその角度に
追随し履帯の突起が転輪から外れないようにしよ
うとするものである。 With this configuration, when the crawler belt attempts to come off the track at a certain angle with respect to the vehicle body, the track wheels follow that angle and the protrusions of the crawler track are prevented from coming off the track wheels.
また該履帯は駆動スプロケツトとアイドラーの
間において、前後方向の中央部が最も緩くなつて
おり、左右回動可能角が大となるのであり、また
前端・後端に行くにつれて左右回動可能角は小と
なるので、この回動可能性に沿つて、転輪側の左
右回動可能角を変化させて、必要以上の左右回動
や、不十分の転輪回動により、履帯の外れが発生
しないように構成したものである。 In addition, the crawler belt is loosest at the center in the front-rear direction between the drive sprocket and the idler, and the angle at which it can rotate from side to side becomes larger, and the angle at which it can rotate from side to side increases as it approaches the front and rear ends. Therefore, in line with this rotation possibility, change the left and right rotation angle of the roller side to prevent the crawler from coming off due to excessive left and right rotation or insufficient rotation of the roller. It is configured as follows.

FIG. 7 is a drawing showing running conditions using a conventional wheel supporting device; FIG. 8, FIG. 9, and FIG. 11 is a side view of the rolling wheel device of the present invention; FIG. 12 is a cross-sectional view of the rolling wheel shaft 14;

まず、第5図、第6図、第13図により、従来
の転輪支持装置による不具合いを説明すると。 First, with reference to FIGS. 5, 6, and 13, the problems caused by conventional wheel support devices will be explained.

因となつていたのである。又、従来4列の転輪で
機体重量を支持していたのが、外側の2列の転輪
のみで機体重量を支持することとなるので、転輪
の破壊や偏摩耗の原因となつていたのである。 Conventionally, the bearing case 11 of the wheel shaft 14 was fixed non-rotatably to a support 15' vertically disposed from the truck frame 10 by means of bolts or pins 17. Therefore, when running with the left and right crawlers placed on the ground surface with different angles in the shape of "〓" as shown in Fig. 5, the tracks 12 and 12 are in close contact with the ground surface, so the inner side of the wheels 9L and 9R is Objects floated up, and the protrusions 12a and 12b protruding from the track tend to disengage from the wheels, which causes the track to come off. In addition, the weight of the machine was supported by four rows of wheels in the past, but now only the outer two rows of wheels support the weight of the machine, which can cause damage to the wheels or uneven wear. It was.
本考案はこの状態を改善して、第7図や第15
図の如く履帯12の傾斜に左右の複列転輪9L・
9Rが追従するように、軸受ケース11を回動軸
16で左右回動自在に支持したものである。 The present invention improves this situation and shows figures 7 and 15.
As shown in the figure, the left and right double-row wheels 9L are attached to the slope of the crawler track 12.
The bearing case 11 is supported by a rotation shaft 16 so as to be rotatable left and right so that the bearing case 9R follows.
トラツクフレーム10より回動軸16の軸受体
15を形にして垂設し、この軸受体15に回動
軸16を枢支している。回動軸16は転輪軸14
の軸受ケース11の中央前後に突出されており、
軸受ケース11は回動軸の回りに左右回動が可能
である。 A bearing body 15 for a rotating shaft 16 is hung vertically from the track frame 10, and the rotating shaft 16 is pivotally supported on this bearing body 15. The rotating shaft 16 is the wheel shaft 14
It protrudes from the front and rear of the center of the bearing case 11,
The bearing case 11 can be rotated left and right around a rotation axis.
左右の複列転輪9L・9Rは転輪軸14に枢支
され、履帯12上を遊転する。左右の2列の転輪
の間を履帯12の突起12a・12bが嵌合され
て、係合状態で移動し履帯が外れないように誘導
されているのである。 The left and right double-row wheels 9L and 9R are pivotally supported by a wheel shaft 14 and freely rotate on the crawler belt 12. The protrusions 12a and 12b of the crawler belt 12 are fitted between the two rows of wheels on the left and right, and are guided so that they move in an engaged state so that the crawler belt does not come off.
又、第3図において、5箇所の左右の複列転輪

る。 Also, in Figure 3, even if all five left and right double row rollers 9a, 9b, 9c, 9b, 9a are pivoted so as to be freely rotatable left and right as in the present invention, the drive sprocket 8 and idler 7 are not supported so as to be able to rotate left and right. Therefore, near the drive sprocket 8 and idler 7, unless the track is guided in the direction returning to the center, a force will act in the direction that forcibly stretches the track, or the track will be prone to coming off at the idler or drive sprocket.
又、履帯は中央部が弛緩するので、中央部は最
も転輪が大きく回動する必要があるのである。 Furthermore, since the crawler belt is relaxed at the center, the wheels need to rotate the most in the center.
これらの点に鑑みて、第3図、第4図、第8
図、第9図、第10図の如く、中央の複列転輪9
c・9cを最も大きい左右回動角が取れるように
左右回動可能角cとし、回動の制限体である軸受
体15cの幅を狭くしたものである。 In view of these points, Figures 3, 4, and 8
As shown in Figures 9 and 10, the central double-row wheel 9
c.9c is set as the horizontally rotatable angle c so that the largest horizontally rotating angle can be obtained, and the width of the bearing body 15c, which is a rotation limiter, is narrowed.

軸受体15aの形状を幅広に構成しているのであ
る。 Similarly, the width of the bearing body 15b of the double-row rollers 9b and 9b at the intermediate position is set to be medium in order to have an intermediate left-right rotation angle b, and the double-row roller wheels 9b at a position near the idler 7 and the drive sprocket 8 are made medium in width. The bearing body 15a, which is a limiting body, is configured to have a wide shape so that the rings 9a, 9a have the narrowest left-right rotation angle a.
(ヘ) 考案の効果
以上の如く本考案は、構成したので、次のよう
な効果が得られるのである。(f) Effects of the invention Since the present invention is constructed as described above, the following effects can be obtained.
第1に、履帯が車体に対して或る角度をもつて
脱輪しようとした時に転輪がその角度に追随し、
履帯のガイド用突起が外れることなく、又、凹凸
の多い路面でも内外転輪が浮動するので、車体へ
の振動が少なく、又、トラツクフレームへの転輪
軸受の装着が容易となるのである。 First, when the tracks try to derail at a certain angle to the vehicle body, the wheels follow that angle,
Since the guide protrusion of the crawler track does not come off and the inner and outer wheels float even on uneven road surfaces, there is little vibration to the vehicle body, and the mounting of the roller bearing on the truck frame is facilitated.
第2に、履帯は駆動スプロケツトとアイドラー
の間において、前後方向の中央部が最も緩くなつ
ており、左右回動可能角が大となるのであり、ま
た前端・後端に行くにつれて左右回動可能角は小
となるのである。 Secondly, between the drive sprocket and the idler, the crawler track is loosest in the center in the front-rear direction, and the angle at which it can be rotated left and right becomes larger, and it is also possible to rotate left and right as it moves toward the front and rear ends. The angle becomes small.
本考案はこの回動可能性に沿つて、転輪側の左
右回動可能角を変化させたので、必要以上の転輪
左右回動や、不十分な転輪左右回動により、履帯
の外れが発生するという不具合いが無くなつたも
のである。 In accordance with this rotation possibility, the present invention changes the angle at which the rolling wheels can be rotated left and right, so the tracks may come off due to excessive left and right rotation of the wheels or insufficient left and right rotation of the wheels. This eliminates the inconvenience that occurs.
