SPOTLIGHT: HYDRAULICS
Piston accumulators
Steering cylinders
Liebherr (Kirchdorf an der Iller, Germany) has expanded its
components portfolio with the launch of series-production
piston accumulators for the 250- and 350-bar pressure
range. Taking another step toward becoming a supplier of
complete hydraulic systems, Liebherr's piston accumulators
serve both mobile and stationary applications and are designed
in accordance with ASME and PED regulations. A
range of piston diameters from 100 to 360 mm (3.94 to 14.2
in.) is available, with oil volumes up to 400 L (106 gal). The
design offers an option to integrate a position transducer
system. Depending on the requirements, the products can
be primed, painted or coated for salt-water protection. The
piston accumulators can be integrated in vertical and horizontal
installation positions and can withstand temperatures
from -40 to +90°C (-40 to +194°F).

Self-locking retaining ring
The Revolox self-locking
ring from Smalley
(Lake Zurich, Ill.) features
a " dimple and
slot " design that safely
and efficiently secures
an application
at high speeds.
Revolox self-locking rings were tested and optimized for secure
high-rpm performance and the dimple-and-slot design is not
easily damaged during installation. Weighing about half that of
a typical retaining ring, the ring's lower weight reduces rotating
mass and therefore increases efficiency in the application.
Automated installation capabilities make the rings a suitable
solution for high production volumes. In addition, Smalley
claims Revolox self-locking rings have an inherently betterbalanced
design that helps decrease vibration.

RAM Industries (Saskatchewan, Canada) custom-designs
and builds hydraulic steering cylinders that provide the force
required to activate a steering system with minimal physical
output. RAM incorporates connection types that provide the
necessary snug fit and tight tolerance and can provide
threaded ends on the outside or inside diameter, allowing
for adjustment of the cylinder length for the final alignment.
Advanced seal packs also can be incorporated to provide
precision movement and holding to ensure consistent control
of the steering function. Other cylinder design options
include position sensing to provide real-time digital or analog
feedback of the cylinder stroke position during operation,
and fail-safe valving to lock the steering cylinder if a
catastrophic failure occurs on the oil lines.

Full-function air dryer
The new Bendix AD-HFi air dryer
features the same design as
the Bendix AD-HF dryer, which
Bendix Commercial Vehicle
Systems (Elyria, Ohio) launched
in 2019, but incorporates a solenoid-operated
valve that replaces
the traditional mechanical
governor allowing for electronic
pressure control. While a
mechanical governor's status
operates within two fixed pressure settings, the Bendix AD-HFi
air dryer's solenoid is controlled by Electronic Air Control software,
which monitors a range of data broadcast across a
truck's J1939 network, including speed, engine torque and rpm.
The software provides diagnostics that help fleets and owneroperators
get optimum use of their dryers and cartridges.
