Bogie
• Free wheels– Wheels are not connected with shaft– The space for shafts is used for low floor
– Good driving features in curves
Petr Sýkora V1 6
Brakes
• Electro dynamic brakes recovering or into resistances– Main brake• Electrohydraulic brakes with disks directly on
Wheels– Park and emergency brake– The pressing forth is performed by spring. Releasing
is performed with hydraulic• Elektromagnetic friction rail brake.
