Dana Introduces TXT Differential

Dana Corporation has introduced a new torque transfer technology (TXT) axle differential
that offers improved torque management in all-wheel-drive light trucks and passenger
vehicles, with a space- and weight-saving design. Dana claims the TXT unit is the first
axle differential with a cost-efficient design for improved handling in all types of
vehicles, including all-wheel-drive vehicles, which are popular with trailerists. TXT can
be mounted on either axle to transfer torque front to rear, or rear to front. It will be
available with electronic controls and can be combined with Dana’s side-to-side Hydra-Lok
differential. The hydro-mechanical technology incorporates an open differential with a
hydraulic pump-and-clutch system that detects wheel slippage and progressively transfers
torque to the nondriving axle. Dana says TXT is unique because it is completely contained
within the axle and does not require a torque-coupling device, such as a transfer case,
saving underbody space and reducing weight. Its location in line with the half-shafts also
eliminates the imbalance vibrations typical of heavier, more complex designs.
