In powered axles, gears that deliver power from the
drive shaft to the left and right axle half - shafts
separately
|
|
|
Allow the left and right wheels to turn at different
road speeds when turning, so that neither wheel has to
scuff |
|
Differentials and Traction
Control |
|
Conventional "open" differentials tend to equalize the
power delivered through both wheels. Thus if one wheel
loses traction - "spins out" on snow, mud, sand, or
gravel - it delivers very little power to the ground.
The other wheel will deliver only the same very little
power. Often this is not enough to keep the vehicle
moving on - it's stuck.
Traction control differentials allow the wheel with
traction to deliver more power than the wheel without
traction. Often this is enough to keep the vehicle
moving. There are two types of traction control
differentials: |
|
|
Locking |
|
|
|
Limited Slip |
|
|
Each type has advantages for specific types of vehicles
and driving conditions. |
Differentials- Locking Type (Speed-Sensitive) |
|
Tractech’s locking differentials are the
NoSPIN® and
Detroit Locker®
brands (same product, different market segments), the
Detroit E-Z Locker™
and Detroit Gearless Locker™
brands. They keep the wheels locked together
(except when turning) so that together the left and
right wheels, always deliver maximum traction to the
ground; neither wheel can spin out.
They allow different wheel speeds in a turn by
disconnecting the faster - moving wheel (usually the
outside wheel - driven faster throughout the turn),
driving the vehicle with the other (inside) wheel.
|
NoSPIN® / Detroit Locker® |
|
|
The most rugged positive locking differential, and most
widely available for axles from 3,000 to 70,000 lb.
capacity. |
|
|
|
For severe operational conditions. |
|
|
Driver may hear and feel "backlash" going from
drive-to-coast and coast-to-drive, as reversing torque
flow resets the components.

Detroit Truetrac®
brand, and the Suretrac®
and the Detroit LSD™
brands (same product, different market segments). They
provide a controlled amount of resistance to a one-wheel
spinout, so that the other wheel (with traction)
receives sufficient power to keep the vehicle moving.
