Primary spring systems

GMT-Chevron springs are multipurpose
vibration-reducing elements,
the individual metals are firmly held
together with vulcanized layers of
Due to their simple installation and
long lifespan, chevron springs are
ideal for use in rail vehicles.
By selecting the angles and the number
of intermediate spring links as well
as the angles of the chevron springs
to each other, three different spring
stiffnesses can be produced, depending
on the direction. Furthermore, the
degree of stiffness can also be varied
by selecting the geometric dimensions
of the individual layers and the corresponding
rubber quality.

GMT-Conical suspension springs
are used e.g. as engine mountings,
aggregate bearings and primary
springs in railway vehicles. Being
vibration insulators and dampers,
conical springs allow a relatively considerable
spring characteristic and
have a progressive curve. Buffers
also help to absorb shock loads without
causing damages to the part. If
different degrees of stiffness are required
in X and Y directions, uses
elements with slots can be designed.

GMT-Rolling rubber-springs are
vibration dampening elements consisting
of a rubber ring, a tapering
metal pin and a metal housing. Their
metal parts and the rubber ring are
assembled by a special process.
Roller-springs are used for dampening
vibrations in rail vehicles. The
characteristics of roller-springs can be
varied as required within their permissible
