Embodiment Construction

[0022] figure 1 The friction ring 10 shown comprises two friction ring halves 12 and 14 which are connected to one another by spacer lugs 16 , not all of which are shown for the sake of clarity. In this case, the free space 18 between the spacer cam 16 and the friction ring halves 12 , 14 forms an air duct system between the friction ring halves 12 and 14 , which serves for the internal ventilation of the friction ring 10 . In order to connect the friction ring 10 radially to the brake disc cover in a form-fit manner, a toothing 22 surrounding the inner periphery 20 of the friction ring half 12 is formed on the first friction ring half 12 . For the sake of clarity, not all of the teeth 24 of the toothing 22 are designed here as helical teeth, ie the tooth flanks 26 , 28 are designed as planes and at an angle to one another. In the axial direction, a through-opening 30 is formed adjacent to the toothing 22 , which opens the inner circumference 20 of the friction ring 10 into t...

Abstract

The invention relates to a brake disk having a brake disk pot (42) and a friction ring (10) which is positively connected to the brake disk pot via a toothing (50). The friction ring (10) comprises two friction ring halves (12, 14), wherein the toothing extends across only one of the friction ring halves. In this manner it is possible to mount through-passages (30) axially adjacent to the toothing running around the friction ring half on the interior circumference of the friction ring, said passages connecting the interior circumference of the friction ring to an interior ventilation arrangement of the friction ring. In this manner both a good transmission of force and a stable positive connection is ensured between the friction ring and the brake disk pot as is an efficient cooling by means of interior ventilation of the friction ring.

Description

technical field [0001] The invention relates to a brake disk of the type specified in the preamble of claim 1 , in particular for a motor vehicle. Background technique [0002] Such a brake disc is known, for example, from DE 10125111 A1. Brake discs of this type comprise a friction ring and a retainer, wherein the friction ring and retainer are connected to each other in a form-fitting manner by tooth profiles in the radial direction of the brake disc. The axial fixation of the friction ring and the holder is achieved by a circumferential snap ring guided in a groove of the friction ring and / or the holder. In this case, the tooth profile is configured as an involute tooth. [0003] This form-locking connection between the friction ring and the holder or the brake disc cover (brake disc housing) via the toothing (teething) secures the two components to one another well in the radial direction, It is also used to transmit force between the brake disc cover and the friction...
