A Mathematical Model of the Dimensional Chain for a Generation 2 Wheel Hub Unit

This article overviews wheel hub design solutions and proposes a mathematical model of the dimensional chain and a tolerance formula for calculating axial clearance for a generation 2 wheel hub assembly with ball bearings. The dimensional chain analysis and its synthesis are carried out using three partial interchangeability methods. The possibility of manufacturing the hub bearing using selection compensation was proposed. The considerations made provide an alternative to the current method of process design based on numerous trials and considerable cost.
