  • the hub at least in Side view, ie in a view in the direction of the wheel rotation axis not in a (or viewed radially within a) surrounding the hub adtrigerfs), but mounted on a shaft journal, wherein the hub surrounds the shaft journal or wrapped in the radial direction, while the outer ring of the Rolling bearing arrangement forms.
  • the solution to this problem is characterized in that the contact surface of the Mrt choirflansches describes a rolling bearing arrangement intersecting plane.
  • Advantageous embodiments and further developments are content of the dependent claims.
  • the Mit videflansch connected to the hub, which is preferably integrally formed on the hub, according to the invention is arranged and shaped such that the said bearing surface is in a vertical, ie perpendicular to the wheel axis of rotation plane that the rolling bearing assembly, ie usually at least a bearing inner race, which may also be formed by a portion of the hub, and a bearing outer ring intersects Further, this plane or at least approximately either intersects or is tangent to a series of rolling elements of the rolling bearing arrangement usually having two rows of rolling or rolling Plane between the two rows of rolling elements.
  • the Mit videflansch can be positioned in a simple manner that results in a common wheel rim (with common dimensions, for example, on passenger cars) a Einpresstiefe in the order of zero or a few millimeters.
  • the hub can form or support an inner ring of the rolling bearing arrangement, which consequently holds an outer ring of the rolling bearing arrangement in or on the Radtriger.
  • the contact surface of Mit instructionalflansches is represented by the fact that a support structure for this on the side facing away from the vehicle body outside of the wheel bearing assembly is guided around the Wälzlager- arrangement around.
  • Support structure with the Mitaspiringflansch and the hub forms a single component.
  • the wheel with its wheel disc or with its spokes or with a radially connecting the radially inner ends of the wheel spokes ring flange on detachable fasteners may be attached to the Mrt lovedflansch in a wheel bearing assembly according to the invention.
  • the fasteners of the vehicle body facing side of the Radlager- assembly can be accessible and thus not visible on the outside of the Radlager- assembly, which not only allows a novel design, but also can contribute to improving the resistance of a thus equipped vehicle.
  • the wheel disc or an annular flange connecting the radially inner ends of the wheel spokes can be screwed onto the hub via a central nut or the like.

  • the hub 30 In the area of the roller bearing arrangement 31, the hub 30 essentially has the shape of a circular cylinder, to which a so-called support structure 30a integrally connects, which merges into a driver flange 30b or carries it.
  • This aligned perpendicular to the axis of rotation 1 and the shape of a circular disc having Mit videflansch 30b forms (in the form of the outside, ie the structure of the vehicle, not shown, and thus also the wheel carrier 4, in the figure right-hand surface of this annular disc) a contact surface 30 c for a brake disk 6 and, subsequently, an annular flange 2 a of the wheel 2.
  • the wheel 2 is constructed as usual, that is, it is the rim 2c of the wheel 2 of a plurality of radially extending and thereby in the respective axis of rotation 1 containing radial plane suitably shaped spokes 2b worn radially inner, ie near the hub 30 ends are connected to each other via the already mentioned annular flange 2a.

  • the carrier flange 30b carried by the support structure 30a and aligned as described may be positioned such that the rim 2c of the illustrated wheel results in a depression of the order of zero or a few millimeters, ie the contact surface 30c of the driving flange 30b lies in a plane perpendicular to the axis of rotation 1, which intersects the rim 2c (approximately) in the middle between the two rim flanges 2h.

Abstract

L'invention concerne un ensemble roulements de roue d'un véhicule dont le moyeu est monté dans un support de roue par l'intermédiaire d'un système de roulements et présente une bride d'entraînement comportant une surface d'appui perpendiculaire à l'axe de rotation d'une roue, et éventuellement un disque de frein intercalé, la surface d'appui de la bride d'entraînement décrivant un plan coupant le système de roulements. Le moyeu forme ou porte une bague intérieure du système de roulements, tandis qu'une bague extérieure est maintenue dans le support de roue et une structure de support de la bride d'entraînement passe autour du système de roulement sur le côté extérieur de l'ensemble roulement de roue opposé à la carrosserie du véhicule. Il est ainsi possible d'atteindre avec une jante de roue usuelle un déport de l'ordre de zéro ou de quelques millimètres.
