Embodiment Construction
[0049] The tire supporting spring and the manufacturing method thereof of the present invention are a major reform and innovation in the tire industry, and are public welfare inventions of great significance. Its implementation will end the history of major tire reforms without the Chinese.
[0050] Since there is no spring steel band, the inventor has made a bicycle tire support spring in 2007 with 65 manganese spring steel wires with a diameter of 1.5 millimeters. After riding, the effect is very good. The single tire load can reach more than 800 kg. The supporting spring for the tire of the white truck can be manufactured with a spring steel strip with a thickness less than 0.2mm and a width greater than 20mm according to preliminary calculations.
[0051] The implementation of the tire support spring of the present invention and its manufacturing method will focus on solving the following problems:
[0052] 1. Determine the spring steel grade. Through the research and ...

Abstract
The invention discloses a supporting spring and a method for manufacturing the same and relates to various tires, in particular to tire supporting spring supporting the cavities of cover tires of various tires. The tire supporting spring is annular spiral spring with a rectangular cross section. When arranged on the inner and outer hubs of the cover tires of the tires, the tire supporting spring is used to replace an inflatable inner tube, thereby making the tires inflation-free tires or solid tires. Redundant metal at the inner side of each circle of spring of the semi-finished product of the tire supporting spring wound and shaped with spring steel strips is cut by a special sand wheel cutting tool, and when arranged on the inner cavities of the cover tires, the inner and outer clearances of between each circle of the tire supporting spring are equal. For a tire supporting spring with poor stability, a special cover tire and a special hub are fixed through the foaming of foaming plastic, so the tire is made into a solid tire.
Description
technical field [0001] The tire supporting spring and the manufacturing method thereof of the present invention relate to various tires, in particular to tire supporting springs and manufacturing methods thereof which are support objects in the inner cavity of various tire casings. [0002] The tire support spring is suitable for various vehicle tires, engineering machinery tires, agricultural tires, aviation tires, etc., and replaces the pneumatic inner tubes of these tires, making these tires become non-pneumatic tires or solid tires, while the existing outer tires do not change. [0003] The tire support spring and its manufacturing method of the present invention also design a method for cutting the excess metal on both sides of the inner side of each circle of the spring for the tire support spring, and a method for fixing the tire support spring with poor overall stability into a solid inner tube, etc. Background technique [0004] Since the French Michelin Tire Compan...
