The advanced powertrain was created by Caterpillar’s Advanced Systems and Controls division, led by Tony Marcott, CVT Engineering Manager. The transmission system from Cat helps the wheel loader to deliver a fuel efficiency improvement of up to 25% to equipment owners.
The OEM – A Split Power SystemĬaterpillar Inc., Peoria, IL, recently announced its 966K XE wheel loader equipped with an advanced powertrain system (a term coined by the company to refer to its internally designed and manufactured CVT).
“The functionality of the transmission is to become the energy management device in the system,” says Bill Klehm, Chairman and CEO of Fallbrook Technologies (Fallbrook), San Diego, CA. The goal of a transmission system, and a key focus with continuously variable transmissions (CVTs), has been to enhance “the big three” features: increase fuel efficiency, reduce emissions and improve overall vehicle performance. Working with other component system experts to create a fully optimized system is completely necessary.” What makes a product good or bad is how you control the components to behave as a whole and not as individual components.

“The biggest integration work is done by the electronic control unit (ECU) and software engineers. Engineering teams designing the transmission system must work with several system experts to optimize a transmission’s communication and seamless cooperation with the rest of the vehicle to create the most effective technology possible.Īccording to CVT Corp.’s founder and CEO Daniel Girard, the control of the clutch is paramount to the efficient operation of the vehicle by the operator. The transmission is a complicated system, interacting with the engine, the hydraulics, the electronics and interfacing directly with the operator and his controls.
