1. A protection device (10) for protecting a brake disk (12) in a disk brake from dirt particles, the brake disk (12) having a pair of side surfaces and a radially outwardly facing edge surface disposed between the side surfaces, said protection device comprising:
at least one protection means (13) configured to cover at least partly the edge surface of the brake disk for effectively preventing dirt particles and on-coming, travel generated wind from directly striking the brake disk (12) associated therewith when said protection means (13) is disposed in a first end position and configured to expose at least partly the edge surface of the brake disk for allowing relative wind to directly strike said brake disk (12) associated therewith when disposed in a second end position,
wherein said at least one protection means (13) is at least partly constructed from material that is shape-influenced by heat such that said at least one protection means (13) assumes said first end position when a temperature of said protection means (13) lies below a first temperature and assumes said second end position when said protection means (13) exceeds a second temperature, wherein said material that is shape-influenced by heat is disposed in an angle between two legs (13a, 13b) of said protection means (13), wherein said protection means (13) is L-shaped in section.
