Increasing Vehicle standards
calls for unique designs
for safer equipment, higher comfort and cost effective solution demands for out
of the box thinking. Our composite air
spring piston with inner volume technology does exactly that for our customers
which is also the reason that we are the benchmark in the industry with leading
OEM´s using our solutions worldwide.
The air spring piston
is a heavy duty and high performance component that helps to protect the payload
and the body of commercial vehicles from the enormous forces caused by
challenging road conditions. The piston together with an air bellow forms a
system solution that carries the entire axle load of the vehicle. The main
function of the piston is to provide stability, whereas the air filled rubber
bellow is attached to the piston to provide springing.
development we provide not only weight savings up to 70% compared to steel but also
help to increase driving comfort. With a customized design, we provide the
vehicle with a higher inside air volume capacity (up to 4 litres) in the air
suspension system. Not to mention a smooth transportation that comes with maintenance free solutions.
how is this possible
A piston can be
mistaken of being simple but it is a rigid polyamide molded component with glasfibre,
where its stiffness and toughness allows it to withstand loads and cushion
shocks. A working piston experiences not only an air pressure of up to 10 bars
but also, in extreme cases, axle loads up to 14 metric tons. To meet these
requirements, we integrate a rib structure into the component which has been
developed through several computerized simulations to find the optimal design and
injection process, ensuring that the piston can withstand the desired load
requirements. Worst case simulations combined with bad road tests confirm that
vehicles with our pistons are equipped for worldwide transport applications.
With the end result of being substantial lighter, more cost effective and
corrosion resistant compared to its metal predecessor.
Keeping overall costs down
To achieve an overall
effective solution, it is not enough to barely consider the design of the component
and choice of material to reach a desired cost level without compromising. We also
provide extensive knowledge in tool design which we combine with our long
production experience, which is a necessity to keep cycle times to a minimum. Our
solutions have a modular construction to cover a variety of applications.
Depending on the type of vehicle and performance profile required, the piston
can be manufactured with different heights by using ancillary components.
