Description
【発明の詳細な説明】 〔発明の技術分野〕 この発明は、オートバイの後ホークに関する。[Detailed description of the invention] [Technical field of invention] This invention relates to a motorcycle rear hawk.
オートバイでは、門型の後ホークの前端を車体に揺動自
在に軸着し、クッションユニットヲ連結して、クッショ
ンができるようべし、後ホークの後端に、後輪の車軸を
連結するようにしている。On a motorcycle, the front end of the gate-shaped rear fork should be pivotally attached to the vehicle body and connected to a cushion unit to create a cushion, and the axle of the rear wheel should be connected to the rear end of the rear fork. ing.
最近では、車重を軽量化して車両性卵を向上するため、
後ホークを軽合金のパイプを主材料として作ることが多
くなって来九。この場合、軽合金の溶接作業は、鉄系の
溶接作業に較べてむつかしく、製造コストが大巾に高く
なる不都合がある。左右のホークを連結する連結金具を
鋳造又は鍛造製にすると、クッションピボットが一体に
できて溶接個所を少くできるが、左右のホークパイプと
の溶接部を合せるのが面倒で、生産性に問題がある。Recently, in order to reduce vehicle weight and improve vehicle performance,
Lately, it has become common for rear forks to be made using light alloy pipes as the main material. In this case, welding of light alloys is more difficult than welding of ferrous metals, and the manufacturing cost is significantly higher. If the connecting fittings connecting the left and right hawks are made of cast or forged material, the cushion pivot can be integrated and the number of welding points can be reduced, but it is troublesome to align the welded parts with the left and right hawk pipes, which poses a problem in productivity. be.
以下、本発明を図面に示す実施例について説明する。 Embodiments of the present invention shown in the drawings will be described below.

る。左右のホークパイプ４は、前端にピボット金具６を
溶着し、後端に車軸金具７を溶着する。The connecting fitting 1 is integrally provided with cushion pivots 2 on both left and right sides, formed by casting or forging, and is integrally welded to the connecting pipe 3. The connecting fitting 1 has a taper on the outside because it is cast or forged. The left and right hawk pipes 4 are made of pipes drawn from a light alloy, and when drawing, they are made into pipes with a rectangular cross section that have sloped surfaces 5 on the inside top and bottom surfaces that match the drawing taper of the connecting fitting 1. Shape. Then, the front inclined surfaces 5 of the left and right hawk pipes 4 are inserted into the outside of the connecting fitting 1 and welded together. The left and right hawk pipes 4 have a pivot fitting 6 welded to their front ends, and an axle fitting 7 to their rear ends.

溶接作業の生産性が向上し、剛性も高くできる。Since the connecting fitting 1fd is formed by casting or forging, the cushion pivot 2 can be made integrally, and the number of welding points can be reduced, resulting in high productivity and low cost. Since the left and right hawk pipes 4 have sloped surfaces 5 formed on their inner upper and lower surfaces, they can be reliably aligned to match the extraction taper of the connecting fitting l, and the alignment can be ensured.
It improves the productivity of welding work and increases rigidity.

製造コストを低減できる。そして、連結金具とホークパ
イプが合致するので剛性も高いものにできる。As explained above, in the present invention, the front parts of the left and right hawk pipes are welded to the connecting metal fittings, and the connecting metal fittings are made by casting or forging, and the left and right hawk pipes are tilted to the inner upper F plane. Since the pipe has a rectangular cross section and is welded so that the inclined surface is aligned with the connecting fitting, the cushion pivot can be integrated into the connecting fitting, reducing the number of welding points, and the connecting fitting can be attached to the inclined surface of the left and right hawk pipes. Since the parts are aligned and welded together, alignment is ensured and productivity is high.
Manufacturing costs can be reduced. Also, since the connecting fittings and the hawk pipe match, it can be made highly rigid.
