Dana Announces New Products At CONEXPO
Spicer TE18 powershift transmission
Dana expands its drive train options for mid-sized front-end loaders and will showcase a 23-ton drive train system for front-end loaders. The new Spicer TE18 powershift transmission is engineered to supply front-end loaders with higher input power capability, reduced maintenance and smoother, quieter operation. Rated from 200 to 260 hp (150 to 195 kW), the TE18 is a four-speed transmission platform using internal components from Dana’s line of powershift transmissions available for the off-highway market.
The R2 hydromechanical variable transmission (HVT) from Dana Rexroth uses a modular platform to deliver a suite of configuration options and software controls, such as direct or remote mounting, flexibility in shift control and drive strategy parameters, and the deployment of up to three PTOs. The R2 HVT is targeted for front-end loaders, motor graders, industrial lift trucks, reach stackers, forestry skidders, and other off-highway applications requiring 180 to 260 hp (135 to 195 kW) of engine output power. Current bench and field tests on frontend loaders with the HVT powersplit systems indicates fuel savings in the drive train of up to 25 percent when compared with the same vehicle outfitted with a conventional torque converter transmission. With field-testing complete, the R2 HVT is undergoing bench testing in the final validation stage, and will be available end of 2014.
Dana expands its Spicer PowerBoost hydraulic-hybrid system for the off-highway market. Designed to fit into existing vehicles, the system captures kinetic energy otherwise wasted throughout the drive train. The working hydraulics then use the recuperated energy to help power the vehicle, which according to the company can reduce fuel consumption by 20 to 40 percent compared with conventional drive train concepts (depending on vocational application and duty cycle). The technology uses an advanced energy-management system to evaluate the levels of power needed in the entire vehicle, predict operating demands, and determine the most efficient means of operation. Hydrostatic energy is captured in an accumulator from the powertrain during low-power operation of the engine and recuperated from braking. “Our field testing results show great promise for adapting our Spicer PowerBoost concepts to numerous construction and material-handling applications,” says Aziz Aghili, president of Dana off- highway driveline technologies.
Dana also introduces its new Victocor 500 cylinder-head gaskets, which are designed with multi-layer steel (MLS) inserts and applicable for use in heavy-duty engines. The gaskets use high-grade rubber-coated stainless steel in place of traditional rubber inserts to provide optimal sealing performance at oil and coolant passages, as well as pushrod openings. A steel core three times thicker than conventional head gaskets increases the stability. The MLS layers are designed to maintain stability over an operating temperate range of -40°F to 450 °F. The Victocor 500 gasket is available in thicknesses ranging from .049 in. (1.25 mm) to .083 in. (2.05 mm) with tolerances of +/- .003 in (0.08 mm).
