Dana Unveils Upgraded TBH Drivetrain at Intermat | Construction News

Dana Holding Corporation has introduced an upgraded drivetrain for compact, hydrostatically driven off-highway vehicles. The new drivetrain offers an optional disconnect feature that improves performance.

Designed for telescopic-boom handlers, wheeled excavators, and front-end loaders, the system includes the enhanced, two-speed Spicer Model 367 shift-on-fly hydrostatic transmission with improved shift quality and a disconnect option that allows the vehicle to disengage one of the axles, which helps to reduce power loss, fuel consumption, and tire wear.

“Equipment buyers demand increased versatility from their machinery, expecting them to perform efficiently and dependably at one work site and then moving quickly to be deployed at the next work site,” said Aziz Aghili, president of Dana Off-Highway Driveline Technologies. “This new system for compact construction equipment is the latest in a series of Dana innovations that improve productivity and reduce vehicle operating costs.”

Compact and versatile, the Spicer Model 367 transmission is engineered with advanced gear-shifting technology that offers a slow speed for working and a fast speed for traveling. It includes a hydraulic motor ranging from 55 to 110cc, and it can be remote mounted or directly flanged to Spicer components.

Other options include hydraulic shifting, gear-engagement and speed sensors, and an integrated spring-applied, hydraulically released (SAHR) parking brake.

Designed for hydrostatic and hydrodynamic drivelines, the Spicer Model 211 industrial planetary steering axle has been upgraded to deliver improved wheel-end torque and load capacity, better brake performance, and reduced power loss in severe and high-speed applications.

Dana is featuring the Spicer Model 367 transmission and Spicer Model 211 axle at Intermat as part of a complete drivetrain for a compact telescopic-boom handler with 6,000 to 8,000-lb. lifting capacity.

It will is configured with Spicer PowerBoost hydraulic-hybrid technology, which features a modular design that offers OEMs flexibility in hybrid control performance, including hydraulic start/stop functionality for use with electronically controlled powertrains, integration with hydraulic work circuits, and other options depending on customer powertrain configuration.

This system demonstrates how off-highway manufacturers can potentially reduce the engine size for applications that currently require an engine at or slightly above the U.S. EPA’s Tier 4 or Euro 5/6 emissions threshold of 75 hp.
