Kinematics Simulation of a New CVT Based on Virtual Prototype Technology

Abstract:

In order to study the kinetic characteristic of a new continuously-variable-transmission (CVT), a three-dimensional model of the CVT was first established by Pro/E solid design and it was saved as Parasolid file format. Then, a kinematics simulation model of drive system of the CVT was established by importing the Parasolid file into ADAMS and the simulation was realized by replacing the traction drive of elasto-hydrodynamic lubrication (EHL) oil film with the contact constraint joints between the input and output wheel discs and the intermediate idler wheels. The simulation results demonstrate that the three-dimensional simulation model of the CVT is accurate, and the equivalent drive system of the CVT is reasonable.
