Embodiment Construction

[0017] The brake disc 1 shown in the figure comprises a brake disc fixing drum 3 and a friction ring 2, and the brake disc is (as usual) provided for fitting on a hub not shown, so that as the hub is During operation, it rotates about the axis of rotation D. The one-piece, internally cooled friction ring 2 made of gray cast iron comprises two friction disks 2 ′, 2 ″ and a cooling ring between the two friction disks and connecting them to each other. Air guide 2"'. The annular friction disc 2 ′, viewed in the axial direction, ie, viewed in the direction of the axis of rotation D, which is closer to the brake disc fixing drum 3 , viewed in the radial direction R (with respect to the axis of rotation D), is smaller by means of so-called fastening projections 9 than The other friction disc 2 ″, which is further away from the brake disc drum 3 in the axial direction, extends further towards the axis of rotation D by a certain (small) amount.

Abstract

According to the invention, a brake disc for a disc brake is provided; the brake disc comprises a brake disc fixing drum and at least one friction ring connected with the brake disc fixing drum through rivets. A section with reduced wall thickness is arranged on the peripheral wall of the brake disc fixing drum; the brake disc is characterized in that the section is an axially directed material recess on the outer circumference of the peripheral wall of the brake disc fixing drum; the material concave part is used for arranging an axially directed rivet as close as possible to the peripheral wall of the brake disc fixing drum; the rivets also individually center the friction ring (2) and the brake disc fixing drum (3) made of light metal to each other.

Description

[0001] This application is a divisional application based on the Chinese patent application with the application number 201480041411.3, the international application number PCT / EP2014 / 064989, the application date is July 11, 2014, and the invention title is "brake disc for vehicles" . technical field [0002] The invention relates to a composite brake disc for a motor vehicle according to the preamble of the first claim. A brake disc is a component part of a motor vehicle braking system mounted coaxially to the wheel, said brake disc having a friction ring and a brake disc holding drum. Here, the brake disc holding drum serves to fasten the brake disc to the hub, while the friction ring is in tribological contact with the brake linings of the brake system during the braking process. As a result, the kinetic energy of the motor vehicle is dissipated in the form of frictional heat and the vehicle is braked. Background technique [0003] Such brake disks can be produced in on...
