Freight bogie

standard gaugemetre gaugedisc brake

The bogie is equipped with axle boxes having a suspension stage with coil springs and hydraulic shock absorbers which are connected to an intermediate frame acting as bogie frame. At one end of this structure, a link made up of elastic articulated arms and connecting rods ensures angular clearance between the bogie and the vehicle body as well as transverse movements. A pneumatic secondary suspension stage located beyond the axle absorbs these angular and lateral movements to dampen the movements between the body and the bogie that are detrimental to passenger comfort. Dampers are installed at the level of the secondary air suspension to limit vertical movements. The linkage by arms and connecting rods on its side guarantees a positioning of the axle perpendicular to the track. Dynamic behaviour The primary suspension consisting of coil springs and hydraulic shock absorbers improves dynamic behaviour and reduces maintenance costs. The secondary stage with its integrated shock absorber system absorbs vertical movements, ensuring great comfort for passengers by limiting parasitic movements between the body and the bogie, which are often uncomfortable on degraded tracks. The braking system is installed on the bogie and provides braking force on the tread in the case of tread brake unit or brake discs calipers (optional). Depending on the chosen application, the bogie can be equipped with a drive axle or a direct mounting of an electric traction motor and its gearbox.
