この考案は、薄板を用い、しかも剛性が高くで
きるように改善したオートバイの後ホークに関す
る。[Detailed Description of the Invention] This invention relates to an improved motorcycle rear fork that uses a thin plate and has high rigidity.
オートバイでは、左右の後ホークの前端を軸管
に溶着し、左右の後ホーク後端の車軸金具に後車
軸を挿通締着し、前端の軸管をフレームに軸着
し、後ホークを揺動させて、後車軸に装着した後
輪がクツシヨンできるようにしている。車軸金具
は、一般に、第１図及び第２図に示すように、中
央に後車軸Ａを挿通する車軸孔Ｂを穿設した厚い
鋼板又は軽合金板製の車軸金具Ｃを設け、同材質
の管製の後ホークＤの後端上下面に切欠きＥを設
け、この切欠きＥに車軸金具Ｃの前部を嵌合せて
溶着している。したがつてこのものでは、溶着個
所が、切欠きＥに嵌合させた個所だけになるの
で、両面で溶着しても剛性が十分でない。又、車
軸金具Ｃは、自体の剛性を高める必要があつて、
厚い板を用いなければ、剛性が十分でない。 On a motorcycle, the front ends of the left and right rear forks are welded to the axle tube, the rear axle is inserted and tightened through the axle fittings at the rear ends of the left and right rear forks, the front end axle tube is attached to the frame, and the rear fork is swung. This allows the rear wheel attached to the rear axle to be locked down. As shown in Figs. 1 and 2, the axle fitting is generally an axle fitting C made of a thick steel plate or a light alloy plate with an axle hole B bored in the center through which the rear axle A is inserted, and axle fitting C made of the same material. A notch E is provided on the upper and lower surfaces of the rear end of the tube-made rear fork D, and the front part of the axle fitting C is fitted into this notch E and welded. Therefore, in this case, the only part to be welded is the part fitted into the notch E, so even if both sides are welded, the rigidity is not sufficient. In addition, the axle metal fitting C needs to increase its own rigidity.
Unless a thick plate is used, the rigidity will not be sufficient.
この考案は、かかる点に鑑み、薄板で軽量であ
り、しかも剛性が十分得られるように改善したも
ので、以下第３図および第４図に示す本考案の実
施例について説明する。 In view of these points, this invention has been improved so that it is a thin plate, lightweight, and has sufficient rigidity.Hereinafter, an embodiment of the invention shown in FIGS. 3 and 4 will be described.
第３図及び第４図は、本考案の一実施例を示す
ものである。鋼板又は軽合金板製の車軸金具１

折曲げて、断面コ字状に成形する。後ホーク４
は、同材質の断面四角形の管製で、後端の上下面

を後ホーク４の切欠き５に嵌合せて、上下縁３を
後ホーク４の後端の上下面の外側に重ねる。そし
て、車軸金具１を、上下縁３部分と垂直部の一側
面の三面で、後ホーク４の後端に溶着する。 3 and 4 show an embodiment of the present invention. Axle fittings made of steel plate or light alloy plate 1
The axle hole 2 is provided in the center, and the upper and lower edges 3 are bent laterally to form a U-shaped cross section. rear hawk 4
is made of a tube made of the same material and has a square cross section, and has notches 5 on the upper and lower surfaces of the rear end. Then, the vertical part of the axle fitting 1 is fitted into the notch 5 of the rear fork 4, and the upper and lower edges 3 are overlapped on the outside of the upper and lower surfaces of the rear end of the rear fork 4. Then, the axle fitting 1 is welded to the rear end of the rear fork 4 on three sides: the upper and lower edge 3 parts and one side of the vertical part.
作用について説明する。 The effect will be explained.
車軸金具１は、上下縁３を折曲げて断面コ字状
のチヤンネル状にしてあるので、板面の剛性が高
く、曲る心配がないので、板厚さを薄く、軽量に
できる。又、車軸金具１は、上下縁３を後ホーク
４の後端の上下面に合せ、垂直部の一側面を、後
ホーク４の内側面内側に合せて、三つの面で溶着
するので、溶着面積も十分とれ、溶着部分の剛性
も高い。こうして、薄板で軽量にできて、しかも
剛性を十分高くすることができる。 Since the axle fitting 1 has the upper and lower edges 3 bent to form a channel having a U-shaped cross section, the rigidity of the plate surface is high and there is no fear of bending, so that the plate thickness can be made thin and lightweight. In addition, the axle fitting 1 is welded on three sides, with the upper and lower edges 3 aligned with the upper and lower surfaces of the rear end of the rear fork 4, and one side of the vertical part aligned with the inner side of the rear fork 4. The area is sufficient and the welded part has high rigidity. In this way, it is possible to make the plate thin and lightweight, and also to have sufficiently high rigidity.

着面積も十分とれて、溶着部の剛性も高く、全体
として、軽量で丈夫にできる。 As explained above, this idea is based on the fact that the upper and lower edges of an axle fitting with an axle hole in the center are bent sideways to form a U-shaped cross section, and a tube-shaped rear fork with a square cross section is installed on the upper and lower surfaces of the rear end of the rear fork. The vertical part of the axle metal fitting was fitted into the notch, and the upper and lower edges of the axle metal fitting and one side of the vertical part were welded and fixed to the upper and lower surfaces and the inner surface of one side of the rear fork, respectively, so that the axle metal fitting itself was shaped like a channel. The thin plate can be made lightweight and highly rigid, the welded area is sufficient, the welded part has high rigidity, and the overall product is lightweight and strong.
