Abstract

The invention relates to a manufacturing method and a structure of a steel wire type locomotive wheel rim. Primarily, an aluminum extruded bar is combined into a circular shape by friction stir welding (Friction Stir Welding, FSW). A plurality of steel wire seats is formed equidistantly on an inner edge of the aluminum extruded bar, and a steel wire fixing hole is formed in each steel wire seat. The aluminum extruded bar is combined with an inner edge of a wheel rim by means of friction stir welding (Friction Stir Welding, FSW). After the wheel rim is processed and a valve hole is formed on the wheel rim, each steel wire seat formed on the inner edge of the aluminum extruded bar is assembled with a steel wire. The steel wire is fixed by the steel wire fixing hole in the steel wire seat, and then each steel wire is fixed with a wheel hub. In this way, there is no need to process steel wire holes on the wheel rim to make it completely airtight, so that in use, it is not necessary to set an inner tire or carry out glue filling operations, but an outer tire can be directly set and inflated to support a vehicle for driving. Thus it is more lightweight during use, so as to increase the practicality and efficiency for the whole implementation.

Description

Steel wire type motorcycle wheel rim manufacturing method and structure

The present invention relates to a method and structure for manufacturing a steel-wire motorcycle wheel rim, and more particularly to a method for obtaining a completely airtight effect without machining steel wire holes on the wheel frame, so that during use, it is not necessary to set an inner tube or perform a filling operation, but can directly set an outer tube and inflate it, so that it can support the vehicle for driving, making it lighter in use and having more practical and effective characteristics in its overall implementation and use.

Motorcycles, cars and other types of vehicles are one of the most common products in daily life, which can greatly shorten the time people spend moving around. In order for a vehicle to run smoothly on the road, the wheel at the bottom of the vehicle is a necessary component. The wheel allows the vehicle to run smoothly on the road. Generally, the wheel is made of metal materials such as aluminum alloy and has a tire on the outer edge of the rim. After air is injected into the tire, the elasticity of the tire and the air injected inside can be used to make the vehicle run more smoothly.

Among them, as for the general steel wire wheel rim, it is mainly arranged with a number of steel wire holes arranged at equal intervals on the inner edge of the wheel frame, so that one end of each steel wire is passed through the steel wire hole for assembly and fixation, and the other end of each steel wire is combined and fixed with the wheel hub assembly. A layer of rubber skin can be first padded on the outer edge of the steel wire wheel rim and then an inner tube can be provided, or a sealant can be filled in the steel wire hole and then covered with an outer tube for vehicle driving use.

However, although the above-mentioned steel wire wheel rim can achieve the expected effect of supporting the vehicle for driving after the inner tube and the outer tube are set, it is also found in its actual operation and use that the steel wire wheel rim has an assembly hole on the inner edge of the wheel frame for one end of the steel wire to pass through and fix, which causes it to be filled with sealant for airtightness, or to be padded with a layer of rubber skin before the inner tube is set, and it is impossible to directly set the outer tube. Not only is it extremely troublesome and inconvenient in use, but after long-term use, it is easy to be affected by the quality of the sealant or the rubber skin is brittle, resulting in poor airtightness, which also causes great inconvenience in its use process, so that there is still room for improvement in its overall implementation process.

Therefore, the inventor, in view of this, has adhered to the rich design development and actual manufacturing experience in the relevant industry for many years, and has further studied and improved the existing structure and defects, and provided a steel wire type motorcycle wheel manufacturing method and structure, in order to achieve the purpose of better practical value.
