@Agritechnica: Dana Unveils New Ag Axles
Dana Holding Corp. has unveiled a new line of steer axles for agricultural machines that incorporate a modular three-piece construction designed to allow reduced time from design to production and delivery while supporting a wide range of customization options.
Through this effort to reduce complexity and streamline its offerings, Dana said it will condense its line of Spicer agricultural axle models from 17 to eight while extending the application range from 33 to 301 kW (45 to 410 hp) and maximum output torques from 2000 Nm to 40,000 Nm.
The new Spicer M25 and M30 axles for tractors, combines, forage harvesters and other agricultural equipment from 67 to 93 kW (90 to 125 hp) are currently available. All other models are set to begin production in early 2014, the company said.
Dana also debuted a range of drivetrain concepts for combines and forage harvesters, including new suspended steer axle and shift-on-fly transmission designs.
Available now, the suspended steer axles delivers increased traction, more stable weight distribution, isolation from body vibration for improved operator comfort and improved handling characteristics while allowing for on-road travel speeds up to 40 km/h (24 mph), the company.
A new three-speed, shift-on-fly hydrostatic transmission concept for combines and forage harvesters up to 36 tonnes (40 tons) is designed to provide a cost-effective system for seamlessly changing speeds in varying field conditions or when transitioning between field operation and on-road travel, Dana said. The system uses advanced gear shifting technology to eliminate the need for stopping the vehicle when shifting gears, supplying virtually the same performance as a powershift transmission at a reduced cost, the company said.
Now in final field testing, the Spicer central tire inflation system (CTIS) is designed to enhance productivity in field operating environments through optimized traction, leak detection, and reduced soil compaction. The company said it can also extend tire life, improve fuel economy and increase vehicle stability during on-road transport.
