This paper presents a mathematical model with five degrees of freedom to
determine the stiffness of the automotive wheel bearing. The mathematical model
consists of two parts. The first part of the developed software solution to determine the
contact stiffness for each rolling elements,while the second part on the basis of
contact stiffness determines the stiffness of bearing based on the finite element
method. Software solution is developed based on Hertz's contact load and John Harris
of the quasi-static equilibrium equations. Contact bearing stiffness matrix is determined
for different arrangements of bearings in the support. Mathematical model analyzes the
influence of the cornering acceleration ofthe automotive wheel and clearance on the
bearnig stiffness. The research in this paper shows that the cornering acceleration of
the automotive wheel significantly affects the radial stiffness, while the clerances
significantly influence the angular and axial stiffness.
