  • Patent number: 10625815
    Abstract: A method for manufacturing a bicycle crank is revealed. After being extended, bent and forged, an aluminum alloy pipe becomes an L-shaped part formed by a cylindrical crankshaft portion and an oval crank portion integrally connected to each other. A plug is inserted into an outer end of the crank portion while a periphery of an outer end of the crankshaft portion is punched to form a shaft-connecting portion. An assembling hole is arranged at the outer end of the crank portion, corresponding to the plug. Thus a bicycle crank is produced. Thereby not only the assembly of the bicycle crank is easier and more convenient, the structural strength of the bicycle crank is increased effectively to against vibrations and impacts. The bicycle is lightweight and the bicycle crank is more streamlined so that consumers are attracted. Thereby the market competitiveness is increased.

  • Patent number: 10065453
    Abstract: A wheel securing structure for trucks is provided. The securing structure generally includes iron screwshaft liners installed in keyholes of mounting parts of aluminum wheels. The bolts of an assembling part correspondingly penetrate the holes of respective screwshaft liners. A first folded edge and a second folded edge are formed on two terminals of each screwshaft liner to respectively insert into conical pits formed on the mounting part of a wheel. The nuts screw onto the bolts of the assembling part to secure the wheel onto the assembling part. When the trucks pass bumpy roads, relative motion caused by vibrations occurs between the wheels and the assembling part, and friction is generated between various parts. The screwshaft liner protects the soft aluminum wheel from being directly rubbed by the bolts, nuts, and the assembling part. Accordingly, the aluminum wheel is made suitable for trucks and other heavy vehicles.
