Paccar's Automated Transmission

摘要

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 designed from the ground up as an automated transmission. It's not a manual box fitted with add-on shift-actuators. Paccar says it's the lightest automated transmission currently in production. Weighing in at 657 pounds - including the clutch and oil - it's about 105 pounds lighter than a comparable transmission, and 200 pounds lighter than the Eaton UltraShift.
