Synthesis of the Mechanisms Used for Reverse Driving on Continuously Variable Transmissions (CVT)

The paper presents two kinematic schemes of the reverse driving mechanism on CVT’s, the first one for rear-wheel drive, and the second one for front-wheel drive. For the first kinematic scheme, the reverse driving mechanism consists of a planetary cylindrical gear set and a multi-disk brake. In order to achieve a better efficiency for reverse driving, the authors propose a new kinematic structure of a planetary cylindrical gear mechanism, simpler than the existing designs. While describing a synthesis of the new kinematic solution, special attention was granted to maintaining the advantages of each of the two existing mechanisms, and highlighting the advantage of using less cylindrical gears.
