Volvo - Matic - The New Automatic Geared Turbine Transmission for Commercial Vehicles

This paper outlines the operation of the Volvo-Matic transmission in its various phases and describes the functions of the automatic control system, its parts, and operating features. The Volvo-Matic is a fully automatic, geared torque converter transmission which has three main components -- torque converter, planetary gear, and automatic control system. Appreciable improvements have been noted in acceleration, maneuverability, smoothness, ease of handling, and in the anticreep and hill-holding device in the Volvo-Matic. Maintenance and servicing are simplified so that a trained mechanic can completely overhaul a Volvo-Matic in 3 hr using standard equipment.
