AI Technical Summary
In the traditional electric vehicle front fork damping adjustment structure, the damping force adjustment depends on the size of the oil hole, and the damping spring and hydraulic damping system are designed independently, resulting in inconsistent shock absorption and resistance effects.
Adjusting the size of the oil hole by rotating the rebound damping knob, and in conjunction with rotating the fork shoulder handle to drive the spur gear, the gear sleeve and the fork shoulder limit rotation, causing the movable sleeve and the contact plate to slide on the internal thread of the gear sleeve, compressing the damping spring, thus achieving coordinated adjustment of damping and spring pressure.
It achieves synchronous adjustment of damping force and spring pressure, improving the shock absorption and handling stability of electric vehicles and optimizing their adaptability to different road conditions.
