Abstract

The invention discloses a lightweight high-strength front fork inner tube of a mountain bike. The front fork inner tube is manufactured from a carbon fiber reinforced titanium alloy material, wherein the carbon fiber reinforced titanium alloy material comprises the following raw materials in percentage by mass: 65%-70% of titanium alloy matrix powder and 30-35% of reinforced fibers; the titanium alloy matrix powder comprises the following components in parts by mass: 80-85 parts of titanium, 5-9 parts of magnesium, 2-5 parts of nickel, 2-4 parts of aluminum, 1-2 parts of molybdenum and 2-3 parts of zirconium; and the reinforced fibers comprise the following components in parts by mass: 25-30 parts of boron fibers, 45-50 parts of carbon fibers and 25-28 parts of silicon carbide fibers. In this way, the lightweight high-strength front fork inner tube has the characteristics of light weight and high strength, and also has good toughness and corrosion resistance.

Description

technical field [0001] The invention relates to the field of bicycle parts, in particular to a light-weight and high-strength mountain bike front fork inner tube. Background technique [0002] Today, many years have passed since mountain bikes were introduced into China. As time goes by, bicycles have become more advanced, more professional, and of course more expensive; in recent years, due to everyone’s awareness of environmental protection and health awareness With the increase of the number of people, cycling has gradually become a kind of entertainment and hobby for everyone. [0003] The front fork is the decisive soul part of bicycle comfort. The front fork part is in the front part of the bicycle structure. Its upper end is connected with the handlebar part, the frame part is matched with the front tube, and the lower end is matched with the front axle part to form the guide of the bicycle. system. Turning the handlebar and the front fork can change the direction o...
