Abstract
The invention relates to a wheel and/or brake disk hub for receiving a one-piece or multi-piece, and notably fragmented, brake disk having friction rings which are preferably connected via links. Said hub is configured such that cams of the hub have shoulders which protrude radially outwards and on one side axially secure the brake disk positioned on the hub. The brake disk is axially stepped at its inner periphery in such a way that a step is formed which is supported on the shoulder.
Claims29
A disk and a hub connection for receiving a one-piece or multi-piece brake disk with friction rings connected by way of links on a hub, wherein the disk/hub connection for connecting the brake disk with the hub being such that
- a) the brake disk has supporting elements on an inner circumferential area;
- b) on an outer circumference, the hub is provided with cams;
- c) U-shaped intermediate elements, which are arranged in a distributed manner in the circumferential direction, are arranged radially between the hub and the brake disk, which intermediate elements have a base section and two longitudinal sections, which are constructed essentially perpendicular to the base section;
- d) the intermediate elements are placed over the cams or supporting elements, so that the longitudinal sections project into spaces extending in the circumferential direction between the cams and the supporting elements to ensure a transmission of brake torque from the brake disk to the hub;
- e) at least one of the cams of the hub having a radially outward-projecting shoulder, which axially secures toward one side the brake disk placed on the hub, the at least one shoulder being shaped in one piece on the axial end areas of the cams;
- and
- f) wherein on the inner circumference, the brake disk is axially stepped such that a step is created for resting on the shoulder.
A hub and brake disk arrangement, comprising:
- a brake disk having supporting elements on an inner circumferential area;
- a hub having cams arranged on an outer circumferential area, at least one of said cams having a radially outward-projecting shoulder shaped in one-piece on axial end areas of the cam, said supporting elements of the brake disk engaging in a toothed manner the cams of the hub when the brake disk is placed on the hub;
- wherein on the inner circumferential area of the brake disk, an axially stepped surface is provided which rests on the radially outward-projecting shoulder of the at least one cam.
