Allison Transmission to Present Latest Propulsion Solutions at Eurosatory 2024

PARIS, June 2024 - Allison Transmission, a leading designer and manufacturer of conventional and electrified vehicle propulsion solutions for tactical wheeled and tracked defence vehicles, and medium- and heavy-duty commercial vehicles, will showcase eGen Force^TM, its electric hybrid propulsion system for armoured combat vehicles, at Eurosatory 2024 (June 17 - 21, Paris Villepinte, Hall 5A, Stand C281). Allison will also present its 3040 MX^TM cross-drive transmission as well as the 9-Speed and 4000 Series^TM fully automatic transmissions for defense ground vehicles.

eGen Force is the newest product in Allison's extensive armoured vehicle portfolio, meeting requirements across a wide spectrum of applications, including the Infantry Fighting Vehicle and future Main Battle Tank markets. eGen Force extends beyond the capabilities of a traditional transmission by functioning as a power distribution system with an electric motor and inverter. This innovative technology provides power for the vehicle and allows for parallel hybrid operation. This enables engine-off mobility, which reduces the risk of enemy detection, including acoustic and thermal detection, key to soldier survivability.

The Allison eGen Force features fully integrated autonomous-enabling drive, steer and braking systems. The eGen Force benefits from Allison's more than two decades of electric hybrid system experience as well as its tracked vehicle system knowledge refined over seven decades. The high-efficiency range pack utilizes eight forward and three reverse gears, providing an efficient 12:1 ratio coverage. The advanced propulsion solution features a 220-kilowatt electric motor and associated inverter for on-board vehicle power and parallel electric hybrid operation. Beyond power generation for auxiliary system capability development, the propulsion solution provides enhanced mobility performance and efficiency with a significant reduction in fuel consumption and reduced thermal and acoustic signatures.

Allison's 3040 MX^TM cross-drive transmission, designed for medium-tracked combat vehicles, provides the propulsion, steering and braking functionalities of the vehicles. Leveraging decades of product development experience, Allison has designed the 3040 MX to accommodate future controls platform evolutions, enabling advancements in system performance over the life cycle of the vehicle.

The Allison 9-Speed fully automatic transmission has been designed to match the most severe operating conditions and provides superior durability and driving performance for defence wheeled vehicles driving in demanding conditions. It has been developed based upon Allison's proven 2000 Series™ automatic transmission featuring six speeds. With nine forward and three overdrive gears, the Allison 9-Speed transmission stands out not only for its reduced fuel consumption but also for its deeper first gear ratio, which improves gradeability and may eliminate the need for a two-speed transfer case in some applications due to its wider ratio coverage compared to the 2000 Series™. While the first and third gears empower more efficient performance at demanding duty cycles, the ninth gear provides greater fuel economy while maintaining performance. The automatic skip shifts and the nine gears to choose from enhance the performance of the vehicle.

Allison Automatics optimize all aspects of operational mobility, including acceleration and on/off road mobility. Continuous Power Technology™ offers uninterrupted power to the drive wheels, smooth take-off, low speed control and manoeuvrability. Superior startability and gradeability are also facilitated by the torque converter/planetary gear design. Transmission-mounted Power Take-Offs (PTOs) provide installation flexibility and the ability to provide power to vehicle-mounted specialty equipment such as self-recovery winches or wrecker systems. The wide range of electronically controlled input and output options provides the ability to integrate vehicle systems such as central tire inflation, locking differentials and blackout lighting.

The crew's vehicle control is paramount to Allison Automatics, which have a proven track record of superior low speed control and manoeuvrability in tight quarters and when towing loads such as mobile artillery. Likewise, the ability to keep both hands on the wheel and both eyes on the path ahead when operating in adverse weather conditions or combat operations reduces operator stress and fatigue.
