Which advantage does a leaf spring have over a coil?

  • A.It locates the axle as well as carrying the load
  • B.A softer rate for the same weight, which gives a better ride quality over a rough or an uneven road surface
  • C.Lower cost only
  • D.A progressive rate, which stiffens as it is deflected and therefore prevents the suspension from reaching its stops

Answer: A

A semi elliptic leaf spring resists fore and aft and lateral forces as well as vertical ones, so no additional links are needed. That simplicity is why it persists on commercial vehicles. Its ride is inferior because of interleaf friction. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision. Most errors here come from carrying across a result from a neighbouring case where it does not hold.
