Description

【考案の詳細な説明】 この考案は、オートバイの車軸の改良に関する。[Detailed explanation of the idea] This invention relates to an improvement of a motorcycle axle.

オートバイは、第１図乃至第４図に示すように、ホーン
１の先端に設けた軸受孔２に車軸３の一端を挿入して、
軸受け４をボルト５で締金せて、車軸３の一端なホーン
１の先端に取着している。As shown in FIGS. 1 to 4, the motorcycle is constructed by inserting one end of an axle 3 into a bearing hole 2 provided at the tip of a horn 1.
A bearing 4 is fastened with a bolt 5 and is attached to the tip of a horn 1 at one end of an axle 3.

車軸３には、ブレーキ保持片６や車輪ノ・ブ７を挿入し
、先端にナツト８を締着して抜止めしである。A brake holding piece 6 and a wheel knob 7 are inserted into the axle 3, and a nut 8 is tightened at the tip to prevent them from coming off.

そして、ナツト８は、着脱のとき、強い力を加えるので
、車軸３が軸受け４に取付けられてはいるものの、回る
ことがある。Since the nut 8 applies a strong force when attaching and detaching, the axle 3 may rotate even though it is attached to the bearing 4.

これをさげるため、車軸３の一端を軸受孔２より外側に
突出９させ、この突出９部分に横孔１０を設げておく。In order to reduce this, one end of the axle 3 is made to protrude 9 outward from the bearing hole 2, and a horizontal hole 10 is provided in the protrusion 9.

そして、ナツト８の着脱のとき、横孔１０に回り止めレ
バー１１を挿入して回転方向に支え、車軸３を回らない
ようにしている。When the nut 8 is attached or removed, a detent lever 11 is inserted into the horizontal hole 10 to support it in the rotational direction and prevent the axle 3 from rotating.

このように、車軸３が側方に突出９していては、当った
場合危険であり、又、ホーン１の外側に取付けるマフラ
等の部品の邪魔になり、マフラ等の部品に逃げ部分を設
ける等の処置をしなげればならず、製作手数がかかつて
コスト高にもなる。If the axle 3 protrudes laterally in this way, it is dangerous if it hits the horn, and it also gets in the way of parts such as a muffler that are attached to the outside of the horn 1. etc., which increases the number of manufacturing steps and costs.

この考案は、かかる点に鑑み改善したもので、以下第５
図に示す本考案の実施例について説明する。This idea has been improved in view of this point, and is described below in the fifth section.
An embodiment of the present invention shown in the figures will be described.

ホーン１の先端に設けた軸受孔２に車軸３の一端を挿入
し、軸受け４をボルト５で締金ぜて、車軸３の一端なホ
ーン１の先端に取着し、車軸３には、ブレーキ保持片６
や車輪ハブＴを挿入して、ナツト８を締着して抜止めす
る点は、従来例に示したものと同一である。Insert one end of the axle 3 into the bearing hole 2 provided at the tip of the horn 1, tighten the bearing 4 with the bolt 5, and attach it to the tip of the horn 1, which is one end of the axle 3. Holding piece 6
The points of inserting the wheel hub T and tightening the nut 8 to prevent it from coming off are the same as those shown in the conventional example.

而して本考案は、軸受け４と車軸３の軸受孔２挿入部分
に、各々横孔１２゜１３を設げる。Accordingly, in the present invention, horizontal holes 12 and 13 are provided in the bearing hole 2 of the bearing 4 and the axle 3, respectively.

横孔１２．１３には、ナツト８の着脱時に回り止めレバ
ー１１を挿入する。A detent lever 11 is inserted into the horizontal hole 12.13 when the nut 8 is attached or removed.

作用について説明する。The effect will be explained.

ナツト８を着脱するとき、横孔１２．１３を貫通するよ
うに、回り止めレバー１１を挿入しておけば、車軸３が
回ることがない。When attaching and detaching the nut 8, if the anti-rotation lever 11 is inserted so as to pass through the horizontal hole 12, 13, the axle 3 will not rotate.

そして、回り止めレバー１１は、横孔１２，１３の端面
で止るので、力を加えて支えている必要がない。Since the detent lever 11 stops at the end faces of the horizontal holes 12 and 13, there is no need to apply force to support it.

又、車軸３は、一端が軸受４ り外力に突出しないので
、邪魔になることもない。Further, since one end of the axle 3 does not protrude from the bearing 4 and is exposed to external force, it does not become a hindrance.

以上説明したように、この考案は、ホーン先端の軸受孔
に車軸の一端を挿入し、軸受けを締金せて車軸を取着す
るものに於て、軸受けと車軸の軸受孔挿入部に跨って横
孔な設け、該横孔に回り止めレバーを挿入できるように
したので、車輪ハブ着脱時に車軸端のナツト操作に対し
、回り止めレバーな横孔に挿入することによって車軸の
回り止めができる。As explained above, this invention was developed by inserting one end of the axle into the bearing hole at the tip of the horn and tightening the bearing to attach the axle. Since a horizontal hole is provided and a detent lever can be inserted into the horizontal hole, rotation of the axle can be prevented by inserting the detent lever into the horizontal hole when the nut at the end of the axle is operated when the wheel hub is attached or removed.

そして、回り止めレバーが、軸受けの横孔と車軸の横孔
に跨ってストッパになるので強く支えている必要もない
。Further, since the detent lever serves as a stopper by spanning the horizontal hole of the bearing and the horizontal hole of the axle, there is no need to strongly support it.

又、車軸は、ホーンの軸受は端から外側に突出しないよ
うにでき、邪魔になることもないので、近接する部品に
逃げ部等を設ける必要もなくなる。Further, since the horn bearing of the axle does not protrude outward from the end and does not get in the way, there is no need to provide a relief part or the like in adjacent parts.

更に、車軸が短くなるので、コストダウン及び重量軽減
も計れる。Furthermore, since the axle is shortened, costs and weight can be reduced.
