本考案は、ブルドーザ等の履帯式建設車両の走
行装置に用いる履帯式走行置で、特にマルチロー
ラ式の履帯を用いた履帯式走行装置に関するもの
である。[Detailed Description of the Invention] The present invention relates to a track-type traveling device used in a track-type construction vehicle such as a bulldozer, and particularly relates to a track-type traveling device using a multi-roller type crawler track.

記リンク１，２に固設された履板である。 The multi-roller type crawler track A is constructed as shown in Figs. 1 and 2, with a pair of left and right links 1,
Rollers 4, 4 are rotatably supported at both ends of a pin shaft 3 supporting the track frame 5, and these rollers 4, 4 come into rolling contact with rails 6, 7 provided on the upper and lower sides of the track frame 5. ing. Note that reference numeral 8 represents track shoes fixed to the links 1 and 2.

ている。 The upper rail 7 in the crawler-type traveling device using the multi-roller type crawler track A is divided in the front-rear direction, and both ends of the rails 7a and 7b are separated from each other, and the top surface of the top end thereof is sloped. can be,
At this part, crawler track A is slackened to the vertical line.

は、第３図に示すように、上側レール７ａ，７ｂ
の実質的なレール部、すなわち、平行部の相互の
終端部の間隔Ｌは履帯ピツチlpの整数倍となつて
いた。 By the way, in the conventional crawler type traveling device, as shown in FIG.
The distance L between the ends of the substantial rail portions, that is, the parallel portions, was an integral multiple of the track pitch lp.
このため第４図に示すように、履帯Ａのけん垂
線の間隔ｌ、たるみｈは履帯Ａが1/2ピツチ動く
につれ、けん垂線の間隔ｌは１ピツチ長いl′とな

ールのたたき音が発生して騒音源となり、またロ
ーラとレール相互の摩耗寿命をも短くなる等の不
具合があつた。 Therefore, as shown in Fig. 4, as crawler A moves by 1/2 pitch, the interval l between the vertical lines of crawler A and the slack h become longer by 1 pitch l', and the slack h is also h. ′ becomes large. That is,
As crawler track A travels, the interval between the vertical lines becomes l←→
At l', the slack changes repeatedly from h←→h', and as a result, crawler track A vibrates in the vertical direction at the part guided by the upper rail, causing the sound of the rail tapping by the rollers. This caused problems such as becoming a source of noise and shortening the wear life of the rollers and rails.
本考案は上記のことにかんがみなされたもの

生及び寿命の低下を防止できるようにした履帯式
走行装置を提供しようとするものである。 The present invention was developed in consideration of the above, and the actual spacing L between the upper rails is L=lp (N±0.5), where the pitch of the crawler track is lp, where N is an integer multiple of the pitch lp, By doing so, it is an object of the present invention to provide a crawler-type traveling device that prevents the perpendicular interval and sag height of the crawler track from changing during running, thereby preventing noise generation and shortening of life due to vertical vibration of the crawler track. That is.
以下本考案の実施例を第５図に基づいて説明す
る。 An embodiment of the present invention will be described below with reference to FIG.
履帯Ａは上記実施例と同様のマルチローラ式の
履帯であり、この履帯Ａはトラツクフレーム（図

ツチをlp、ピツチ整数倍をＮとしたときに、Ｌ＝
lp（Ｎ＋0.5）となる間隔になつている。 The crawler A is a multi-roller type crawler similar to the above embodiment, and this crawler A is a multi-roller type crawler that is similar to the above embodiment.
It is guided and supported at points a and 10b. The rail spacing L between the upper and lower rails 10a and 10b is defined as L=
The interval is lp(N+0.5).
本考案は上記のようになるから、履帯Ａが1/2
ピツチだけ移動した状態でも、履帯Ａのけん垂線
間隔ｌ及びたるみ高さｈは変化しない。 Since the present invention is as described above, crawler track A is 1/2
Even if the crawler track A is moved by a pitch, the perpendicular interval l and the slack height h of the crawler belt A do not change.
従つて走行中における履帯Ａの上下方向の振動
がなく、このため履帯Ａの上下方向の振動により
騒音の発生が防止されると共に、履帯Ａの寿命の
低下を防止することができる。 Therefore, there is no vibration in the vertical direction of the crawler belt A during running, which prevents the generation of noise due to the vertical vibration of the crawler belt A, and also prevents the life of the crawler belt A from decreasing.
