How to Reduce Unsprung Mass?

[SarahRose]

Methods to reduce unsprung mass include: 1. Using lighter wheels; 2. Using lighter suspension arms. Unsprung weight refers to the mass of the suspension, wheels or tracks, and other components directly connected to them, excluding other parts supported by the suspension. Unsprung weight includes numerous components such as axles, wheel bearings, hubs, tires, part of the drive shaft, shock absorbers, and suspension links. The car suspension is installed between the body and the running gear, serving to support the body and reduce vibrations. If viewed from the elastic elements of the suspension towards both ends, the upper part carries the entire body and a portion of the chassis components, while the lower part presses another portion of the chassis components towards the ground. The mass of the upper part is the sprung mass, and the mass of the lower part is the unsprung mass.
