Kinematic and power characteristics of the elastic wheel while rolling with camber and convergence

Abstract

Abstract Vehicles steering wheels are installed in such a way that the plane of the wheel makes a certain angle with vertical plane (so-called camber angle) and at the same time is located at an angle to machine movement direction (toe-slip angle). These angles result in lateral force, increased contact slip and increased wear on the wheel tread. In the article, from phenomena consideration occurring in the contact of an elastic wheel with a rigid base, kinematics and rolling mechanics issues of elastic wheels installed with camber and convergence are considered; dependences are derived that allow determining the wheel power and kinematic parameters, toe and camber angles optimal ratio from the point of view of reducing the wheel running track rolling resistance and wear is determined.
