A combined spring-and-shock-absorber system for supporting wheel suspensions or axles on a vehicle body has a tubular roll bellows (U-bellows) arranged between a wheel-bearing or wheel-controlling connection and a connection on the vehicle body side, the bellows being arranged between an outer bell and a rolling piston, the outer bell and the rolling piston, in each case, having at least partially varying diameters over the height of the corresponding component, and having walls that contact the tubular roll bellows. Both ends of the tubular roll bellows being sealingly secured on the rolling piston at segments having different diameters, the lower mounting section having a larger diameter than the upper mounting section. For this purpose, a tubular roll bellows is used, which is configured as a differential roll bellows, whose interior is filled with a fluid and communicates with a hydraulic accumulator supported on the chassis and/or vehicle body. On the basis of the present invention, a combined spring-and-shock-absorber system is developed, which contains a friction-free displacement device in a thin construction.

A brake unit comprising at least one brake and at least one brake pad having at least one friction lining is described. The brake has a disk brake with a brake rotor made of a ceramic-metal composite (CMC) whose outer surface or surfaces at least partially form a friction surface for the at least one friction lining, and a disk brake cup that is mounted on the disk brake by way of one or more mounting elements. The friction surface of the disk brake has a hardness of approximately 1600 to 2500 HV, and the at least one friction lining has a coefficient of friction of approximately 0.3 to 0.5. The disk brake cup and/or the mounting elements form a corrosion-inhibiting attachment to the disk brake. The brake unit can be operated in corrosion-free fashion over a service life of at least approximately eight to 10 years or approximately 200,000 to 300,000 km.
