LAS VEGAS, March 11, 2008 At CONEXPO-CON/AGG 2008 today, Dana Holding Corporation announced the launch of the Spicer® Model 369 shift-on-fly hydrostatic transmission, which provides a proven alternative to expensive powershift solutions or sliding collar range shift transmissions. The Model 369 transmission was specially designed to enhance mobility, comfort, and ease of use for operators in mid-sized construction, mining, and material-handling vehicles.
The Spicer Model 369 transmission is an extremely cost-effective means of allowing seamless operation from reverse, full stop, and all the way to speeds of 40 kph and beyond. Vehicles equipped with traditional range shift solutions must completely stop before shifting between ranges, but the new gearbox on the Spicer Model 369 transmission allows for quick shifting from low to high range while moving.
This transmission is composed of a single hydrostatic motor featuring a transfer case with low and high gear ratios that integrates the drivetrain system into the engine™s controller area network (CAN) to improve shift quality and reduce acceleration jerk during vehicle operation.
The Spicer Model 369 transmission builds on the success of previously released Spicer® shift-on-fly hydrostatic transmissions designed for telescopic boom handler, front-end loader, and wheeled excavator applications. The Spicer Model 369 transmission offers a compact layout with a 151 mm drop and can be remote-mounted as well as vertically or horizontally flanged to the axle. It provides a 700 Nm continuous input torque, with 4500 RPM maximum input and a wide combination of ratios with a deepest first gear ratio of 7.4. This transmission is also available with an optional spring-applied hydraulically released (SAHR) park brake, which reduces the number parts and eliminates the need for a separate external park brake.
Dana™s hydrostatic transmissions have already been used in more than three dozen different customer applications, said Rick Honeyager, director of product planning for the Dana Off-Highway Products Group. The Spicer Model 369 transmission has received a particularly enthusiastic response from European OEMs, and we are seeing increased interest from North American OEMs looking to develop compact vehicles with hydrostatic solutions.
The Spicer Model 369 transmission is on display this week in Dana™s booth at CONEXPO-CON/AGG, located in the Las Vegas Convention Center™s South Hall, Booth S-16313.
