Wheel bearing arrangement having spur toothing
View Patent ↗A wheel bearing arrangement which has at least two rows of rolling bodies for mounting a wheel hub which can be driven with the wheel bearing arrangement by a drive element. The wheel hub is connected to the drive element, and the wheel hub and the drive element engage positively into one another via a pair of mutually corresponding spur toothings. In the wheel bearing arrangement, a value of greater than three is obtained for a ratio of the diameter of a toothing reference circle of the spur toothing in the wheel bearing arrangement to the rolling body row spacing of the at least two rows of rolling bodies.
1. A wheel bearing arrangement, comprising:
at least two rows of rolling bodies for mounting a wheel hub which can be driven with the wheel bearing arrangement by a drive element, the wheel hub being connected to the drive element, and the wheel hub and the drive element engaging in a form-fitting manner into one another by means of a pair of mutually corresponding spur toothing systems,
wherein a ratio of a diameter of a toothing reference circle of the spur toothing system which is on the wheel bearing arrangement side to the rolling body row spacing of the at least two rows of rolling bodies is realized to be greater than three.
2. The wheel bearing arrangement of claim 1 , wherein a ratio of the diameter of the toothing reference circle of the spur toothing system, which is on the wheel bearing arrangement side, to the diameter of the rolling bodies of one of the at least two rows of rolling bodies is realized to be greater than four.
3. The wheel bearing arrangement of claim 1 , further comprising:
an inner ring, which is seated on the wheel hub for one of the rows, the inner ring being axially at least held on the wheel hub by means of a collar which is formed radially to an outside from a hollow section of the wheel hub,
wherein a ratio of the inner ring seat diameter to the bearing cross-section is realized to be greater than 2.2.
4. The wheel bearing arrangement of claim 1 , wherein a ratio of the bearing external diameter to the diameter of the toothing reference circle of the spur toothing system, which is on the wheel bearing arrangement side, is realized to be smaller than 1.8.
5. The wheel bearing arrangement of claim 1 , further comprising:
an inner ring, which is seated on the wheel hub for one of the rows, the inner ring being axially at least held on the wheel hub by means of a collar which is formed radially to an outside from a hollow section of the wheel hub,
wherein a ratio of the inner ring seat diameter to the bearing width is realized to be greater than 1.15.
6. The wheel bearing arrangement of claim 1 , further comprising:
an inner ring, which is seated on the wheel hub for one of the rows, the inner ring being axially at least held on the wheel hub by means of a collar which is formed radially to an outside from a hollow section of the wheel hub,
wherein a ratio of the inner ring seat diameter to the diameter of the rolling bodies of one of the at least two rows of rolling bodies is realized to be greater than four.
7. The wheel bearing arrangement of claim 1 , further comprising:
an inner ring, which is seated on the wheel hub for one of the rows, the inner ring being axially at least held on the wheel hub by means of a collar which is formed radially to an outside from a hollow section of the wheel hub,
wherein a ratio of the inner ring seat diameter to the rolling body row spacing of the at least two rows of rolling bodies is realized to be greater than 2.7.
