BRAKE DISK AND MODULAR SYSTEM
A built brake disk for a wheel brake of a vehicle, in particular an automobile, has two friction rings, between which a plurality of spacers are arranged to form cooling ducts of an internal ventilation of the brake disk, and further has a nave, which is arranged coaxially with the friction rings and is firmly connected to the friction rings and/or to a plurality of spacers.
1 . A built brake disk for a wheel brake of a vehicle, the built brake disk comprising:
two friction rings;
a plurality of spacers disposed between said two friction rings and disposed to form cooling ducts defining an internal ventilation of the built brake disk; and
a nave disposed coaxially with said friction rings and firmly connected to at least one of said friction rings and said plurality of spacers.
2 . The brake disk according to claim 1 ,
further comprising fasteners; and
wherein said spacers each have at least one passage formed therein, through said passage one of said fasteners is fed, said fasteners fastening said two friction rings together.
3 . The brake disk according to claim 1 , wherein said nave is one of attached and cast onto at least one of said friction rings and said plurality of spacers.
4 . The brake disk according to claim 1 , wherein said spacers are disposed in a star-shaped pattern.
5 . The brake disk according to claim 1 , wherein at least some of said spacers protrude radially inwards beyond an inner edge of said friction rings, and are there connected to said nave.
6 . The brake disk according to claim 1 , wherein said spacers are separated from one another in a circumferential direction, for forming said cooling ducts of said internal ventilation between said spacers.
7 . The brake disk according to claim 1 , wherein at least one of said spacers and said friction rings are formed as identical parts.
8 . The brake disk according to claim 1 , wherein at least one of said friction rings is a ceramic friction ring.
9 . The brake disk according to claim 1 , wherein the brake disk is for an automobile.
10 . A modular system for building brake disks, the modular system comprising:
friction rings;
spacers; and
naves, said friction rings, said spacers and said naves defining a first configuration;
said plurality of spacers can be disposed between said two friction rings and disposed to form cooling ducts defining an internal ventilation of a brake disk, said nave to be disposed coaxially with said friction rings and firmly connected to at least one of said friction rings and said plurality of spacers.
11 . The modular system according to claim 10 , wherein at least one of said friction rings, said spacers and said naves is also present in at least one further configuration.
