Carraro launches concept variable transmission transaxle

Carraro DriveTech, the Italian-based manufacturer of axles, transmissions, and epicycloidal drives displayed a concept transaxle designed for agricultural and other off-highway applications at the recent Agritechnica. The transaxle, named VaryT, introduces a Torotrak toroidal transmission in place of a hydrostatic/shunted hydrostatic drive in a transaxle casing.

“At the heart of any variable-speed transmission is the variator, and in the Carraro VaryT it's a very high efficiency mechanical unit across a wide speed range, which is unlike some of the hydrostatic options. It's a very power-dense solution, which means we can have a compact overall transmission, ideal for small tractors,” Roger Weyman, the Agricultural Director of Torotrak, told SOHE.
