Historic manufacturer of passenger vehicles, CFD has a wide range of bogies for railcars or multiple-unit. The latest addition to the range is a double-stage suspension bogie for passengers transport up to 120 km/h.
Design
It consists of an H-shaped bogie frame structure placed on the axles. The primary suspension stage consists of coil springs and one hydraulic shock absorber per axle box. The secondary stage consists of air suspension and vertical and lateral shock absorbers. Traction rods provide the link between the bogie frame and the body and the shock absorbers limit pitch, yaw and roll movements. The air pressure in the secondary suspension flanges is controlled to correct the body height according to the load.
Its 2.4m wheelbase and the structure of its chassis allow it to be equipped with CFD DC traction motors or conventional traction solutions using axles and cardan shafts connected to permanent magnet motors or a gearbox. The connection between two driving axles is made by cardan shafts. Each wheel is equipped with a tread brake unit for service braking and immobilisation functions. Disc brakes or electromagnetic brakes are also possible.
