Abstract
The invention relates to a disk brake unit for a vehicle wheel including a hub and a brake disk. The brake disk includes an outer ring and an inner ring, the inner ring and the outer ring being non-rotatably linked together. The outer ring includes a friction ring. The inner ring includes an internal surface with inner dogs for contacting a hub. The brake disk is adapted to prevent heat from being transmitted from the friction ring to the internal surface.
Claims11
A disk brake unit for a vehicle wheel comprising:
- a hub having a rotational axis, the hub including an external surface having outer dogs;
- and
- a first brake disk having an inner ring and an outer ring that are non-rotataby linked, the outer ring having a friction ring, the inner ring including an internal surface having inner dogs adapted to contact the external surface of the hub such that the first brake disk is slidable in the direction of the rotational axis but solidly connected to the hub in a circumferential and radial direction, and the first brake disk including a means to prevent heat from being transmitted from the friction ring of the outer ring to the internal surface of the inner ring, the means being arranged between the friction ring and internal surface and including the inner ring being made from a material with very low thermal conductivity.

- a first brake disk having an inner ring and an outer ring that are non-rotataby linked, the outer ring having a friction ring, the inner ring including an internal surface having inner dogs adapted to contact the external surface of the hub such that the first brake disk is slidable in the direction of the rotational axis but solidly connected to the hub in a circumferential and radial direction, and the first brake disk including a means to prevent heat from being transmitted from the friction ring of the outer ring to the internal surface of the inner ring, the means being arranged between the friction ring and internal surface;
- a drag bearing having at least one holding device for fastening the drag bearing and the drag bearing having a cylinder of a cylinder and piston unit;
- and
- wherein the drag bearing includes a wheel carrier which receives a wheel bearing, and an external joint positioned within the wheel bearing, wherein the hub is fastened to the external joint in such a manner that it is separated from and axially offset relative to the wheel bearing.
