AI Technical Summary
When the rear wheel of a motorcycle is connected to the frame via the suspension, the accumulated tolerances on the engine frame and the rear swingarm axis cause the rear swingarm to clamp and deform, increasing motion resistance, reducing the service life of the powder metallurgy bushing, and reducing handling performance when cornering and on uneven roads.
The suspension system employs a support shaft and a bushing assembly, with the bushing assembly positioned between the rear swingarm assembly and the support shaft. The bearing assembly is made of POM plastic. Adjustable and limiting components eliminate gaps formed during manufacturing, improving connection tightness. Needle roller bearings are used instead of deep groove ball bearings to reduce wear and cost.
It improves the stability and handling of motorcycles, extends the service life of suspension components, reduces production costs and wear, and enhances the safety and economy of the entire vehicle.
