The XE version of Caterpillar's 966K wheel loader has a continuously variable transmission (CVT) that helps improve the number of tons of material moved per unit of fuel up to 25 percent.
Cat's integrated CVT replaces a traditional drive line's torque converter with a hydraulic pump and motor (variator unit), which allows for smooth, continuous ratio changes between engine speed and machine speed. The variator runs much cooler under heavy load than a torque converter, and the allows the engine to run in a more efficient operating range (Working range: 1,250 to 1,600 RPM).
Power is also transmitted through the CVT in a parallel mechanical gear path that is much like a powershift transmission. It is combined with variator power through a series of planetary gear sets. Transmission operation is automated and transparent to the operator.
