Suspension

[1] The assembly of springs, shock absorbers, torsion bars, joints, arms, etc., that cushions the shock of bumps on the road and serves to keep the wheels in constant contact with the road, thereby improving control and traction.
[2] A mixture of fine, non-settling particles of any solid within a liquid or gas. The particles are the dispersed phase, while the suspending medium is the continuous phase; used engine oil, for example, is a suspension with suspended combustion residues which produce a blackish appearance.
