Which quantity is the wheel rate of a suspension?

  • A.The rate at which the wheel deflects under load, expressed as a proportion of the load carried by the vehicle
  • B.The spring rate measured at the wheel
  • C.The rate of the spring itself, which is quoted by the manufacturer and is independent of the suspension geometry
  • D.The damping rate

Answer: B

Because the spring usually acts on the arm inboard of the wheel, the rate felt at the wheel is the spring rate multiplied by the square of the motion ratio. Only the wheel rate determines the ride frequency. Confusing the two is a common error. A symptom that appears under one condition and not another is what narrows the diagnosis quickly. Naming the cost of a choice alongside its benefit is what turns a fact into a design decision.
