SF 1000<br />
<strong>Motor</strong> <strong>and</strong> <strong>Trailer</strong> <strong>Bogies</strong> <strong>for</strong> Light Rail <strong>Metro</strong> <strong>Vehicles</strong><br />
The SF 1000 motor <strong>and</strong> trailer bogies are<br />
designed <strong>for</strong> use on light weight metro<br />
vehicles with a maximum speed of<br />
80 km/h. The maximum axle load is 13 t.<br />
The modular bogie family SF 1000 is<br />
designed <strong>for</strong> high per<strong>for</strong>mance with low<br />
life cycle cost.<br />
This bogie family is of modular design<br />
causing to a reduction in the number of<br />
different components required <strong>and</strong> thus<br />
resulting in rationalisation of<br />
manufacture.<br />
The wheelbase of 2100 mm enables the<br />
bogies to be track friendly <strong>and</strong><br />
particularly suitable <strong>for</strong> negotiating<br />
small radii of curvature. The primary<br />
suspension system is equipped with<br />
pairs of steel coil springs. Rubber<br />
guidance elements inside of the springs<br />
provide axle guidance free from play.<br />
The secondary suspension system<br />
features air springs <strong>and</strong> offers optimum<br />
ride quality as well as the possibility of<br />
level adjustment.<br />
The secondary longitudinal guidance is<br />
achieved by low connected guides<br />
(traction rod). This arrangement ensures<br />
low wheel load reduction.<br />
One disc brake per wheelset is provided<br />
as mechanical brake. The installation of<br />
magnetic rail brakes is alsoprovided<br />
(option).<br />
