Eaton taps into electric, connected expertise

ATLANTA, Ga. – Eaton’s commercial vehicle group is leveraging broader automotive and electric expertise as it prepares for a future that is increasingly electrified and connected. A newly launched e-mobility business segment – combining elements of the company’s vehicle group and electrical business – is one of the latest signs of that. “There’s going to be a requirement for more power electronics on board,” observed Larry Bennett, director of vehicle technology and innovation, referring to the possibility of three-voltage systems on commercial vehicles. Eaton Electrical, currently responsible for 60% of company revenues, will help to apply lessons from buildings, leading to new smart power management tools and power distribution strategies, he said. There’s already been an increase in electric powertrains for buses and lighter vehicles, of course. And Eaton expects fully electric valvetrain actuation to be a reality within a decade. Hydraulic lash adjustments, now used in passenger cars, could soon manage intakes and exhaust in heavy vehicles as well.

Test Drive: Paccar unveils 12-speed automated transmission

Paccar is the latest North American truck manufacturer to bring a proprietary automated transmission to market. Called the Paccar Automated Transmission, it's a 12-speed, twin countershaft design that was conceived as an automated transmission, which is to say, it was designed that way. It's not a manual box fitted with add-on shift-actuators. Paccar says it's the lightest automated transmission currently in production. At just 657 pounds, it is nearly 200 pounds lighter than Eaton's Advantage AMT. The addition of the automated transmission completes Paccar's goal of having a fully integrated proprietary powertrain. Paccar says its new transmission has been performance-optimized for MX-series engines and the new 40,000-pound drive axles unveiled in October 2016.
