Virtual Lower Kingpin

Branch ID: 310

Request Number: 50000310

Description: Virtual Lower Kingpin X, Y, and Z Location

Note - The kingpin axis on an SLA or Macpherson strut suspension is defined by two points (the upper ball joint and the lower ball joint in the SLA suspension, the upper strut mount location and the lower ball joint in the case of the Macpherson strut suspension) When the kingpin axis is not defined by two distinct points, it must be calculated virtually, using the motion of the spindle to calculate the instant axis of rotation of the knuckle. The virtual requests (numbers 50000310-50000350) use this method to calculate the kingpin location, and parameters that rely on the kingpin location. These requests should be used on suspensions that do not have a clearly defined kingpin axis, such as a 4 link or 5 link front independent suspension.
