First claim
Opening claim text (preview).
The invention claimed is: 1. A device for protecting a wheelset axle of a rail vehicle, the device comprising: an elastomeric mat to be placed on the wheelset axle and retaining means configured to retain said elastomeric mat on the wheelset axle; a housing of a rigid material disposed for at least partially enclosing said elastomeric mat, said housing having two mutually facing free ends each facing a wheel when said housing is mounted, and said free ends having incisions formed therein, said incisions defining tongues having tongue free ends, said tongue free ends being said two mutually facing free ends of said housing. 2. The device according to claim 1 , wherein one or both of said elastomeric mat or said housing are configured, after mounting, for extensively and completely enclosing the wheelset axle. 3. The device according to claim 1 , wherein one or both of said housing or said elastomeric mat consist of a plurality of separate parts. 4. The device according to claim 1 , wherein said housing is made of sheet metal. 5. The device according to claim 1 , wherein said retaining means are selected from the group consisting of hose clips and clamping fasteners. 6. The device according to claim 1 , wherein said housing is formed with at least one overlap deflection for forming an extensive housing overlap. 7. A rail vehicle, comprising at least one wheelset axle provided with a device according to claim 1 . 8. A bogie, comprising at least one wheelset axle provided with a device according to claim 1 . 9. The device according to claim 1 , wherein said tongues of the housing for allowing the housing to be bent to match a geometry of the wheelset axle.
