Definitions

• Rolling bearings in particular for the storage of a commercial vehicle wheel
• the invention relates to a rolling bearing, in particular for the storage of a commercial vehicle wheel according to the preamble of claim 1.
• tapered roller bearings are used which, with a relatively small installation space, have a high load-bearing capacity and are particularly suitable for the intended purpose.
• wheel bearing constructions are known in which the tapered roller bearings are designed as single bearings, which, however, require a relatively large installation space.
• tapered roller bearings are now combined to form so-called compact wheel bearing units, in which the inner rings of the tapered roller bearings face each other on the front side.
• compact wheel bearing units in which two arranged in O arrangement angular contact ball bearings are provided, but compared to tapered roller bearings have a lower load capacity, so that they are less suitable for use in heavy commercial vehicles.
• tandem oblique ball bearings should be mentioned in which the axial force support is rectified in contrast to the O arrangement, the balls of one of the two rows of balls having a larger diameter and are often arranged in a larger diameter circle than the Balls of the other ball row.
• the higher load capacity of the tapered roller bearings is paid for by higher frictional losses compared to angular contact ball bearings, which leads to a correspondingly higher fuel consumption, which accounts for up to 1%, for example, in a commercial vehicle with ten wheels.
• the invention has for its object to further develop a rolling bearing of the generic type so that its capacity and durability is optimized with minimum space requirements.
• Such a rolling bearing now combines the high load capacity of a tapered roller bearing with the long service life of a ball bearing, while minimizing the overall height.
• the available installation space can be kept relatively small in a wheel hub with the result of a weight saving, as it is constantly sought in vehicle construction.
• the rolling elements forming the inner bearing rows are smaller in their rolling radius than the balls of the associated angular contact ball bearings, wherein the rolling elements of the inner bearing rows can also be formed as balls, but also as barrel or cylindrical rollers.
• the inner bearing rows are designed in the sense of angular contact ball bearings, which are preferably present together with the associated outer angular contact ball bearings in tandem arrangement.
• the new rolling bearing as a whole forms a double-tandem angular contact ball bearing.
• each outer angular contact ball bearing and the associated inner bearing row on a common inner ring so that the rolling bearing is provided with a total of two inner rings.
• the rolling bearing can have a common outer ring for all four rows of bearings. It is also conceivable, each pair of rolling bearings, consisting of an inner and an outer bearing row to provide with an outer ring, depending on space or assembly requirement.
• the rolling radii of the inner roller bearings are preferably smaller than the rolling radii of the outer roller bearings.
• the running diameter of the inner bearing rows may be smaller than that of the outer angular contact ball bearings. It is also conceivable, however, to arrange the inner and the outer bearing rows on a same diameter of the running circle.
• the two bearing rows of each bearing pair can be positioned at different support angles. To achieve a maximum support width, the respective outer balls of the angular contact ball bearings are arranged in a large support angle, the two inner rows of bearings to achieve maximum radial load capacity with lower support angles.
• the inner bearing rows can also be designed as pure radial bearings. In this case, rolling bodies are used to minimize an axial space requirement in the form of said barrel or cylindrical rollers.
• a precisely fitting arrangement can be done by the end-side lying inner rings or by means of appropriately sized spacers.
• the connection of the two inner rings by means of a known inner ring-Stoßabdichtung.
• FIG. 1 shows a mounted rolling bearing according to the invention in a longitudinal section
• 2 to 4 each show a further embodiment of a rolling bearing according to the invention, also in a longitudinal section.
• 1 shows a built-in a wheel hub 1 of a commercial vehicle bearings 3 is shown, wherein on the wheel hub 1, a brake disc 2 is attached.
• the rolling bearing 3 consists of two pairs of bearings 4, which together form a compact rolling bearing.
• the new rolling bearing basically two inner rings 5 and that to each pair of bearings 4 a. These inner rings 5 are connected to each other by a shock seal 10, with the adjustment of the bearing clearance can be done.
• each bearing pair 4 has its own outer ring 6.
• the rolling bearing 3 is provided with two angular contact ball bearings 7 arranged in an O arrangement which each form an outer bearing ring.
• each angular contact ball bearing 7 is assigned a row of rolling bodies which face each other and form inner bearing rows 8.
• the inner rows of bearings 8 are also designed as angular contact ball bearings and arranged with respect to their support so that they together with the outer bearing row, ie the angular contact ball bearing 7 each form a so-called tandem arrangement.
• the rolling elements of the inner bearing rows 8 are formed as balls 9 whose diameter is smaller than the diameter of the balls 9 of the angular contact ball bearing 7th
• the divided outer rings 6 are supported with their mutually facing end faces on an annular shoulder 16 of the hub 1, while the opposite sides of the rolling bearing 3 are closed by a sealing ring 14 and a shaft seal 15.
• FIG. 2 of a roller bearing 3 which essentially corresponds to that of FIG. 1, a one-part outer ring 6 is provided, while the arrangement and configuration of the bearing pairs or bearing rings correspond to the figure 1.
• the rolling bearing 3 is mounted on a shaft 11.
• the support angle, with which the balls 9 abut against axial forces on the inner ring 5, is here designated by ⁇ .
• FIG. 3 shows an example in which the rolling bearings of the inner bearing rows 8 consist of barrel-shaped rollers 12 which are arranged in the manner of deep groove ball bearings and serve only to absorb radial forces.
• the barrel-shaped rollers 12, which may otherwise consist of flattened balls on both sides, are kept very small in their overall height, so that a total of the installation of the rolling bearing 3 results in a small footprint.
• the inner bearing rows 8 each have a cylindrical rollers 13 formed rolling elements, which also absorb radial forces.
• the outer ring 6 is designed in one piece.
• the new rolling bearing is also characterized by an extremely simple installation.
• the Kugein 9 of the angular contact ball bearings are preassembled on the respective inner ring 5 and the inner bearing rows 8 in the outer ring 6. Thereafter, the inner rings 5 are inserted into the outer rings 6 and the shock seal 10 is mounted.
