Power-Split Cvt-A New Transmission Epoch for Agriculture Vehicles
Published September 25, 1997 by Institution of Mechanical Engineers in United Kingdom
Continuous variable transmissions are the optimal drives for agricultural vehicles.
New concepts of hydrostatical-mechanical power split systems controlled by a modern electronical management enable stepless transmissions with overall efficiencies competitive with today's power shift transmissions for tractors. The measured efficiency ratios also meet the required targets determined for future tractor drivelines.
A new operating mode preselecting system enables the transmission operation behavior to be matched to the wanted vehicle works in the most favorable manner.
With a lot of advantages, such as comfort, easy control, automatic regulation and integration with a vehicle management system, these kinds of transmissions are going to start up a new transmission epoch for agricultural vehicles
