この発明はトラクタの明き走行車両の前車輪支架装置に
関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a front wheel support device for a tractor-type vehicle.
小型機では前車輪のトレッドが狭いので、操向ハンドル
を一杯に回向操作するときは、第１図に平面視を模型的
に示し定ように前車輪［２１が前部車体（３）の下部（
ボンネットのサイドカバーの下部）に接触することにな
って危険であるので１例えばるが、このようＶＣ最大回
向角が小さく抑えられる結果、魂胆半径が大きくなって
いわゆる小廻りがきかないことになる。In small aircraft, the front wheel tread is narrow, so when turning the steering wheel all the way, the front wheel [21 is shown in a schematic plan view in Figure 1] on the front body (3). beneath(
This is because it is dangerous to come into contact with the bonnet side cover (lower part of the side cover), but as a result of keeping the maximum VC turning angle small in this way, the radius of rotation becomes large and so-called small turning cannot be done. .

の発明に卦すては次の技術的手段を構じた。Therefore, in order to eliminate collision accidents due to the force of the front wheels, the following technical means have been adopted in this invention.

たものである。That is, the pivot position (A,) of the front wheel (5) ((11) relative to the front axle housing (7) is set to the steering turning center (02) of the front wheel (51% (6)) of the front axle housing (7). ), this makes it possible to secure a wide gap +81 between the front vehicle on the inside of the turning direction and the front vehicle body +81, and it is possible to fully turn the steering wheel and maintain stability. This has the effect of eliminating the risk of the wheels (6) coming into contact with the front vehicle body (3) even when the wheels (6) are in contact with the front body (3).
