Company IntroductionFounded in 1984, FULONG is a national
high-tech enterprise now and ISO9001, TS16949 certified. With
national lab and municipal innovation center, we made over ten
national and trading standards. What's more, 30,000 square meters
were expanded to build several automatic production lines in
automotive timing belt and PK belt, which guarantee the OEM
quality.Product DescriptionHanover, February 2009. BMW, ZF Steering
Systems and ContiTech have developed an electromechanical steering
system (Electrical Power Steering, EPS) with an axially parallel
layout (APA), which has been employed successfully in the BMW
1 and BMW 3 series since 2006 and has thus proved itself
in a production application. The system makes an important
contribution to environmentally friendly and optimally comfortable
driving since it reduces energy consumption, which in turn reduces
CO2 emissions, and requires only minimal steering effort. ContiTech
has developed a slanted-tooth belt, CONTI SLT POWER, for the
timing belt drive for the electric power steering. The
electromechanical steering system from BMW, ZF Steering Systems and
ContiTech consists basically of an electric motor,
a recirculating ball screw spindle and a timing belt
drive. In contrast to hydraulic versions, an electro-mechanical
servo system of this type requires no energy in straight-ahead
driving and consequently reduces fuel consumption significantly
- by up to 0.3 liters per 100 kilometers. It also reduces CO2
emissions noticeably. In addition, EPS-APA optimizes driver comfort
because very high forces of up to 13 kN are developed through the
recirculating ball screw spindle at the tie rods with minimal
steering effort. Steering effort can additionally be adjusted to be
speed-dependent and progressive through suitable software.
A further environment-related benefit of EPS-APA is that the
system does not need hydraulic fluid. Because the EPS system is of
modular construction, it can easily be used in different types of
vehicles. Extreme demands are made on the timing belt drive of the
EPS steering system. In contrast to a belt that operates in an
engine environment, the belt in the steering gear must withstand
very low temperatures just above the road surface. It was for this
reason that the ContiTech Power Transmission Group developed the
CONTI SLT POWER timing belt. SLT stands for "Super Low Temperature"
because the belt is designed for a temperature range from -40°
C to +120° C. "In testing, the CONTI SLT POWER timing belt
operated flawlessly even at peak readings of -45° C and +130°
C. This advance was made possible by using a special EPDM
low-temperature elastomer that is highly resistant to aging, cold
and heat," explains Hermann Schulte, manager for Research and
Development at ContiTech Power Transmission Group. The integral
fiberglass cord additionally gives the belt especially high fatigue
strength under reversed bending stresses, water resistance and
dimensional stability. The comfort benefit of a particularly
low noise level additionally played a great role in
development by BMW, ZF Steering Systems and ContiTech. The sprocket
profile and the belt profile have been specially developed for this
application with a five-degree helix angle, thus ensuring
trouble-free tooth engagement and optimized acoustics. To ensure
that no belt generates a noise level higher than 45 dB, every
single belt is tested for its acoustic characteristics before being
delivered. "This is a volume typically found in the average
library," is the comparison made by Schulte. Each single belt is
given an individual identification mark during production to ensure
uninterrupted product traceability that is required for steering
systems. The timing belt drive offers a high degree of
overload protection: Under extreme loads, the belt can jump without
being damaged. The high quality of the products makes
a maintenance-free life of more than 15 years possible for the
entire steering system. size list:Shipped By: Contact
