Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
184 words
A disk brake arrangement in a vehicle, comprising a wheel means having a wheel hub connected with wheel spokes, said wheel means being supported unilaterally at a wheel guide means, said wheel hub being operatively connected with a support hub rotatably supported at the wheel guide means as well as with a brake disk means, the brake disk means including an axially extending brake disk hub which is clamped in between the support hub and the wheel hub by way of a central connecting means, characterized in that said wheel hub has a central axially extending portion which is centered in a stepped through bore of the brake disk hub, said brake disk hub being non-rotatably connected with said wheel hub and on its outer circumferential surface being centered and connected in a non-rotatable manner in the support hub, whereby the suppot hub is located in the region of the connection of the brake disk hub and the wheel hub, and wherein said central connecting means clamping said brake disk hub between said support hub and said wheel hub is a central threaded bolt.

Claim 4
Dependent Claim
25 words
A disk brake arrangement according to claim 2, wherein the wheel hub includes raised portions juxtaposed the brake disk means with a slight spacing therebetween.
