SF 3000
Motor and Trailer Bogies for Heavy Rail Metro Vehicles
The SF 3000 motor and trailer bogies are
designed for use on heavy weight metro
vehicles with maximum speeds of
80 km/h and a maximum axle
load of 17 t.
This bogie family is of modular design
causing to a reduction in the number of
different components required and thus
resulting in rationalisation of
manufacture.
The wheelbase of 2300 mm enables the
bogies to be track friendly and
particularly suitable for negotiating
small radii of curvature.
The primary suspension system is
equipped with pairs of conical rubber
springs, ensuring good self damping
characteristics and longitudinal and
lateral flexible axle guidance.
The secondary suspension system
features air springs and offers optimum
ride quality as well as the possibility of
level adjustment in the secondary
suspension.
The secondary longitudinal guidance is
achieved by low connected guides
(traction rod). This arrangement ensures
low wheel load reduction.
Wheel disc brakes are provided as
mechanical brake. The installation of
magnetic rail brakes is also provided
(option).
By use of proven design components
(further development of the bogie
SF2000) we have developed an efficient
bogie family of the highest reliability
with perfect maintainability, high
flexibility and excellent running
behaviour.
