Stepless goes Electric: eAutoPowr TRANSMISSION I JOHN DEERE

The all-new John Deere eAutoPowr is the first electromechanical splitpath IVT

To create the new eAutoPowr transmission, the hydraulic pump and motor used in the AutoPowr transmission were replaced with two electric motor-generators. One generator is directly connected to the diesel engine and powers the second motor-generator which precisely controls the tractor speed.

One electrical and 4 mechanical gears guarantee the most efficient power transfer to the wheels. This results in a most durable and reliable stepless transmission with the proven efficiency and ride comfort of AutoPowr . The best stepless transmission John Deere has ever designed.

The liquid-cooled, brushless electric motor-generators in the new eAutoPowr are entirely maintenance-free. Replacing hydro modules with electric components greatly reduces wear parts, simplifies the design and improves the overall transmission life. Electric drive components and new sensors reduce the need for special diagnostic tests by 1/3 and reduce 20% of the procedures requiring special tools or equipment.

100.000 customer equivalent test hours through the development process guarantee the best in class reliability

Working in partnership with Joskin, we have developed a slurry tanker with an electric motor, which drives 4 of the 6 wheels for a total of 8 driven wheels in this combination. The tractor no longer has to pull the entire load, as the trailer is pushing too, utilising the weight of the slurry and the tanker for additional traction. The result is you can use a much lighter tractor to pull bigger loads or to climb up steeper hills reducing soil compaction, saving fuel and increasing productivity.
