Technical Field

[0002] The front fork is located at the front of the bicycle structure. Its upper end is connected to the handlebar assembly, the frame assembly mates with the head tube, and its lower end mates with the front axle assembly, forming the bicycle's steering system.
[0003] Linkage suspension forks are the core shock absorption components of vehicles such as mountain bikes and off-road motorcycles. They connect the fork body to the frame through multiple linkage structures, and together with springs, dampers and other components, they achieve the shock absorption function. The principle is that when the vehicle encounters bumps, the impact force of the road pushes the fork to compress. The linkage group transmits the force and changes the force trajectory at the same time. The spring absorbs the impact energy, and the damper slows down the spring rebound speed to suppress vibration.
[0004] Traditional linkage suspension forks often struggle to balance filtering out low-speed, small vibrations with providing support for high-speed, large impacts when faced with different road conditions. The single-stiffness linkage structure can result in harsh feedback during slight vibrations or excessive compression during severe impacts, affecting riding stability.
[0005] Therefore, it is necessary to provide a linkage-type shock-absorbing fork assembly to solve the above-mentioned technical problems. Utility Model Content
