AI Technical Summary

Problems solved by technology

This means that the heat is not the same on either side of the disc, which in turn can lead to a different cooling rate between the sides of the disc
This difference may have an effect on the so-called deformation behavior of the brake disc and ultimately on the possible formation of thermal fractures

Embodiment Construction

[0048] figure 1 This is already stated in the introduction to the description as prior art.

[0049] figure 2A schematic perspective view of a disk brake 10 according to the invention with a brake disk 1 according to the invention is shown.

[0050] The coordinate system x, y, z is used for orientation. The x-coordinate extends in the forward direction of travel of the vehicle (not shown) to which disc brake 1 is assigned. The y-coordinate extends over the width of the vehicle, wherein the z-coordinate extends over the height of the vehicle.

[0051] Disk brake 10 is shown here only by two friction linings 9 . The structure of such a disc brake 10 can be taken, for example, from document EP 0 566 008 A1.

[0052] The brake disk 1 according to the invention is also an internally ventilated brake disk 1 with an inner friction ring 2 and an outer friction ring 3 . The brake disk axis 1a extends in the y-direction, about which the brake disk 1 is rotatable.

Abstract

The invention relates to a brake disc (1) for a disc brake, in particular for a motor vehicle, in the form of an internally ventilated brake disc (1) having an inner friction ring (2) and an outer friction ring, which oppose each other and are spaced from each other and connected to each other with connecting pieces (5), forming an interstice as a cooling channel, wherein the outer friction ring is connected to a hub, and a first number of connecting pieces (5) has cross-sections of different size over a longitudinal axis of each connecting piece (5). A second number of connecting pieces (5) in the first number of connecting pieces (5) are connected to one another.

Description

technical field [0001] The invention relates to a brake disc for a disc brake according to the preamble of claim 1 . The invention also relates to a disk brake with a brake disk. Background technique [0002] Such a brake disk is part of a vehicle brake, which is also designed as a disk brake. Various operating modes, such as pneumatic, hydraulic, electrical, and combinations thereof are also used for operating such disc brakes. The disc brake is pressed via a pressing mechanism, for example a brake torsion bar, which is connected to a compressed air cylinder or can be actuated by an electric drive unit. [0003] A moving vehicle can be braked by means of disc brakes in order to reduce the speed of the vehicle or to bring the vehicle to a complete stop. During braking, the brake disc converts kinetic energy into heat energy in combination with the friction linings of the disc brake. During this energy conversion, the brake disc undergoes a heating cycle and a cooling cyc...
