Abstract
A wheel hub for a utility vehicle includes a brake element abutment surface against which a brake element bears in an installed state, and a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and/or a receiving region for a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state.
Claims24
A wheel hub for a utility vehicle, comprising:
- a brake element abutment surface against which a brake element bears in an installed state, wherein the brake element includes a brake disk or a brake drum;
- and
- at least one of a positive-locking arrangement which interacts in positively locking fashion with the brake element in the installed state as viewed in a direction of rotation, and a receiving region for a positive-locking arrangement which interacts in positively locking fashion with the brake element in the installed state as viewed in the direction of rotation;
- wherein a primary relief is provided for the axial fixing of the brake element;
- wherein the primary relief opens out in the brake element abutment surface;
- and
- wherein, for force boosting during a rotation of the brake element about an axis of rotation, the positive-locking arrangement has an edge profile which extends in a direction of rotation and which runs eccentrically with respect to the axis of rotation.

A wheel hub for a utility vehicle, comprising:
- a brake element abutment surface against which a brake element bears in an installed state, wherein the brake element includes a break disk or a brake drum;
- and
- at least one of a positive-locking arrangement which interacts in positively locking fashion with the brake element in the installed state as viewed in a direction of rotation, and a receiving region for the positive-locking arrangement which interacts in positively locking fashion which the brake element in the installed state as viewed in the direction of rotation;
- wherein a primary relief is provided for the axial fixing of the brake element;
- wherein the primary relief opens out in the brake element abutment surface;
- wherein the positive-locking arrangement is arranged in the region of the brake element abutment surface or is part of the brake element abutment surface;
- wherein the positive-locking arrangement includes at least one of a shoulder, a collar and a groove in the brake element abutment surface;
- wherein the shoulder is one of multiple shoulders, and wherein a common edge profile extends over the multiple shoulders as viewed along the direction of rotation;
- and
- wherein, for force boosting during a rotation of the brake element about an axis of rotation, the positive-locking arrangement has an edge profile which extends in a direction of rotation and which runs eccentrically with respect to the axis of rotation.

A wheel hub for a utility vehicle, comprising:
- a break element abutment surface against which a brake element bears in an installed state, wherein the brake element includes a brake disk or a brake drum;
- and
- at least one of a positive-locking arrangement which interacts in positively locking fashion with the brake element in the installed state as viewed in a direction of rotation, and a receiving region for the positive-locking arrangement which interacts in positively locking fashion with the brake element in the installed state as viewed in the direction of rotation;
- wherein a primary relief is provided for the axial fixing of the brake element;
- wherein the primary relief opens out in the brake element abutment surface;
- wherein a central point assigned to an edge profile of the positive locking arrangement is offset with respect to an axis of rotation by an eccentricity;
- and
- wherein a ratio between the eccentricity to the extent of the brake element abutment surface as measured in a radial direction is between 0.2 and 0.8.
5 more elements
A brake system, comprising:
- a brake element;
- and
- a wheel hub for a utility vehicle;
- wherein the wheel hub has a brake element abutment surface against which a brake element bears in an installed state, and at least one of a positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state, and a receiving region for the positive-locking arrangement which interacts in positively locking fashion, as viewed in a direction of rotation, with the brake element in the installed state;
- wherein the wheel hub has a primary relief for the axial fixing of the brake element;
- wherein the primary relief opens out in the brake element abutment surface;
- wherein the positive-locking arrangement interacts, in the installed state, with a brake-element-side positive-locking arrangement, in particular a brake-element-side positive-locking arrangement which is of complementary design with respect to the positive-locking arrangement of the wheel hub;
- and
- wherein, for force boosting during a rotation of the brake element about an axis of rotation, the positive-locking arrangement has an edge profile which extends in a direction of rotation and which runs eccentrically with respect to the axis of rotation.
