The objective of Bonatrans is to provide its customers with comprehensive solutions to their needs. This has led to the development and production of brake disks using our own design. At the present time Bonatrans is able to offer its customers brake disks with optimized design and material structure.

Design types of brake disks:

• for assembly on the axle

Application	Admissible speeds / axle loading	Brake disk weight	Diameter outer / hub hole
Pro osobní dopravu	140 km/h / 16 t	98,5 -116 kg	590 / 158,5 - 610 / 195
Pro nákladní dopravu	140 km/h / 25 t	138 kg	610/322

• for assembly into wheel

Development of brake disks

• 2D and 3D modeling
• FEM analysis
• Flow analysis
• Tests on the brake stand for evaluation of temperature fields and resistance to deformations and thermal cracks
• Service life tests – wear and tear
• Operating tests
