Fastening element for fixation of a wheel on a wheel axle
A fastening element for fixation of a wheel on a wheel axle has a first section and a second section that are movable relative to each other and are separated from each other by a plane of separation. The first section has devices for fixation on the wheel axle. The second section has a wheel axle cover. A substantially closed outer wall that is divided by the plane of separation is provided on the fastening element.
1. A fastening element for fixation of a wheel on a wheel axle, said fastening element being a monolithic part and comprising:
a first section and a second section that are movable relative to each other and are separated from each other by a plane of separation, wherein said first and second sections are connected to each other by an articulation;
wherein said first section comprises devices for fixation on the wheel axle;
wherein said second section comprises a wheel axle cover;
wherein said first and second sections have a first position and in said first position said first and second sections are resting on each other;
wherein, in said first position, said wheel axle cover covers said devices for fixation on the wheel axle in a direction of the wheel axle;
wherein said first and second sections have a second position and in said second position said first and second sections are pivoted away from each other; and
wherein, in said second position, said devices for fixation on the wheel axle and said wheel axle cover are positioned so as to not overlap each other in the direction of the wheel axle.
2. The fastening element according to claim 1 , comprising a substantially closed outer wall that is divided by said plane of separation.
3. The fastening element according to claim 2 , comprising a locking rim for fixation on a groove of the wheel axle.
4. The fastening element according to claim 3 , wherein said wheel axle cover and said locking rim, viewed in a direction perpendicular to said outer wall, overlap at least partially.
5. The fastening element according to claim 3 , wherein said locking rim has a substantially elliptical inner contour.
6. The fastening element according to claim 3 , comprising a receptacle for receiving an end section of the wheel axle.
7. The fastening element according to claim 6 , comprising a support wall that connects said locking rim and said outer wall to each other, wherein said outer wall is provided on said first section.
8. The fastening element according to claim 7 , wherein said support wall at least partially delimits said receptacle for the end section of the wheel axle.
9. The fastening element according to claim 7 , wherein said support wall has a slot in an area that is adjacent to said second section.
10. The fastening element according to claim 9 , wherein said support wall has actuation sections on either side of said slot, wherein said actuation sections are inclined away from each other in a direction relative to said outer wall.
11. The fastening element according to claim 10 , wherein said outer wall has an engagement opening adjacent to said actuating sections.
12. The fastening element according to claim 1 , comprising at least one locking hook for attaching the fastening element on the wheel.
13. The fastening element according to claim 12 , wherein said plane of separation divides said at least one locking hook.
14. A fastening element for fixation of a wheel on a wheel axle, said fastening element comprising:
a first section and a second section that are movable relative to each other and are separated from each other by a plane of separation;
wherein said first section comprises devices for fixation on the wheel axle;
wherein said second section comprises a wheel axle cover;
a support rim as a stop for an outer ring of a roller bearing.
15. The fastening element according to claim 1 in the form of an injection-molded part of plastic material.
