NVH driveshaft options
Leading the industry-wide eff ort to improve
NVH performance, Dana has also developed
its own technology to address growing market
needs and is continually working
to improve these innovative
technologies. Th e Spicer
AdvanTEK 40 tandem axle
incorporates quiet gear technology.
Spicer driveshaft s are
designed with NVH performance
in mind.
Earlier this year, Dana
introduced the SPL 350 Lite
driveshaft as the next generation
of lightweight, durable
driveshafts optimized
for downspeeding on hightorque
commercial trucks.
Th is series of driveshaft s has
been precision engineered
to meet the industry’s NVH
needs in a high-performance
design. To address vehicle
sensitivity, this design has
resulted in one of the most
precisely balanced driveshaft
s in the industry.
Th e SPL 350 Lite driveshaft
is up to 35 lbs lighter than
existing products, making it
the lightest weight driveshaft
in its class. Off ering improved
performance, enhanced
vehicle dynamics and easier
maintenance, the SPL 350 Lite
driveshaft also delivers the
durability and reliability required to support
torque-management needs resulting from fast
axle ratios to enable engine downspeeding.
Th is positions Dana for powertrains of the
future that enable further engine downspeeding,
supporting axle ratios lower than 2.26.
Th e solutions in the SPL Lite Series of
driveshaft s have been designed specifi cally
with fl eets in mind – with fewer components,
reduced weight, and improved NVH
performance.
Th ese driveshaft s share service components
with their existing SPL Series counterparts,
increasing ease of service and
simplifying inventory for truck owners and
service facilities.
While the
driveshaft or
tires are often
assumed to be
the NVH culprit,
the problem
of vibration in
the powertrain
should be
handled with
a systematic
approach.
