Brake disc has friction rings connected rotationally secured to support with a guide and seal inbetween to keep out dirt and prevent corrosion

摘要

The brake disc has an axially fixed support (3) and several friction rings (10) with at least one guided axially displaceable on the support through a guide (4) which has between the support and friction ring a seal (6) such as a folding bellows to seal off the surroundings of the brake disc and keep out dirt and prevent corrosion. At least one friction ring can be formed integral with the support. The support can be a separate component mounted rotationally secured on an axially secured wheel hub (2).
