In the automotive industry, the hollow shaft plays a very important and indispensable role, and it not only has the highest potential coordination of natural bending frequency and torsional stiffness at the lowest weight. Moreover, the hollow shaft allows the natural bending frequency and torsional stiffness to be adjusted to the user's needs. At the same time, for most hollow shaft applications, the damper is no longer needed, saving material and reducing the overall weight of the car.
The hollow pipe rod is made of seamless steel pipe.
The seamless steel pipe is a circular, square, rectangular steel with a hollow section and no seams around it. The seamless steel pipe is formed by perforating a steel ingot or a solid tube blank, and then hot rolled, cold rolled or cold drawn. The seamless steel pipe has a hollow section and is used as a pipe for conveying fluid. Compared with a solid steel such as round steel, the steel pipe is light in weight when it has the same bending and torsional strength, and is an economical section steel, which is widely used in manufacturing structures. Parts and mechanical parts, such as oil drill pipes, automotive drive shafts, bicycle frames, and steel scaffolding used in construction.
