The three-dimensional model of a Half Toroidal Continuously Variable Transmission (HT-CVT) was established by CAXA solid design. The kinematics simulation of the HT-CVT was realized by replacing the traction drive of elasto-hydrodynamic lubrication (EHL) oil film with the contact constraint joints in ADAMS. The angular velocity curves of the power rollers and the output cone disk on the HT-CVT were obtained. Simulation results demonstrate the fluctuation of the angular velocities on the two power rollers and the output cone disk compares well with the conclusion derived from the actual gear ratio of the HT-CVT.
