Truetrac Differential
The Truetrac is the leading helical gear-type
limited slip differential in the industry. Eaton has a
proven track record of producing the most
effective and dependable traction differentials in
the world.
Truetrac's patented design of parallel axis,
planetary helical gears, provides a smooth and
quiet, automatic division of torque. Power transfer
is so smooth, it literally goes unnoticed by the
driver - even in front wheel drive axles. Because
of Truetrac's smooth operation there is no affect
on braking characteristics or fuel consumption.
Under normal driving conditions, Truetrac
performs like an open differential.
On wet, muddy, icy or loose terrain, imbalanced
gear forces automatically transfer power to the
wheel with the highest traction. The Truetrac
limited slip differential responds instantly to torque
feedback providing needed traction, anytime, at
any speed.
Engineered to work efficiently. Proven design, low cost and effective
performance, all make the Truetrac limited slip
differential the ideal choice for a wide variety of
vehicle applications, including emergency
vehicles, walk-in vans, motor homes, SUVs,
landscape and delivery trucks.
Traction Control
The Truetrac performs like an open differential
under normal conditions, and automatically
transfers torque to the wheel with the highest
traction when required. The Truetrac can transfer
up to 3.5 times more torque to the high traction
wheel. This torque transfer ratio (called the bias
ratio) is accomplished by using helical side gears
and pinions. The bias ratio is the result of
pressure exerted by the side gears and pinions
against the surface of the differential case. In
certain applications, this normal gear engagement
may produce temporary driver feedback.
