An overview over the modeling issues of a toroidal traction drive is given. A traction drive consists of a loading cam, a hydraulic feedback control circuit and two toroidal cavities, each of them including two discs and two power rollers. The modeling of both the mechanical and the hydraulic components is discussed. An existing rheology model is used to describe the tangential forces generated in the contacts between the discs and the rollers. The transmission ratio is feedback controlled by a hydraulic circuit which is modeled according to mechanical principles. Finally, simulation results of transmission ratio changes are compared with measurements.
