Abstract

A wheel hub bearing comprising at least one inner bearing member 510 arranged to be fixed to a shaft, at least one outer bearing member 501, a first intermediate bearing member 509 positioned radially between the inner bearing member and the outer bearing member and a second intermediate bearing member 508 positioned radially between the inner bearing member and the outer bearing member. Each intermediate bearing member is freely rotatable relative to the other bearing members. Preferably the wheel hub bearing comprises one or more rows of rotating elements (fig 3, 307, 303) positioned radially between the inner and outer bearing members, separated by the intermediate bearing members. The rotating elements may be cylindrical or spherical.

Description

The present invention relates to the field of wheel hub bearing assembly and can be used where there is a need for a wheel hub bearing assembly between a fixed body and a wheel. The wheel hub bearing assembly is especially suitable for high rotational speeds and/or where it is desirable with low friction.
Background
The present invention relates to any wheel hub bearing assemblies, but especially wheel hub bearing assemblies applied between a fixed body and a wheel. In a wheel hub bearing assembly between a fixed body and a wheel it is difficult to combine low friction with high rotational speed and high load. High friction leads to high temperatures, and high temperatures might damage the lubricant and this yield shorted service life for the wheel hub bearing.
Known wheel hub bearing assembly have a relatively short lifetime due to friction and wear. It is desirable with extended service life and a more energy efficient solution.
Patent US1494695 (A) and US2475493 (A) utilizes a low friction roller- and ball bearing with parallel rows of rotating elements. Patent US7954600 B2 has the aim to reduce power losses in an internal combustion engine. Patent US1494695 (A) and US2475493 (A) utilizes a low friction roller- and ball bearing with parallel rows of rotating elements. Patent US 2012051679 A utilizes an aircraft spherical bearing assembly comprises a first part which is in sliding contact with an intermediate part for sliding therebetween to form a spherical joint.
Patent GB 2284237 A utilizes A spherical bearing comprises an outer housing having an inner concave surface, an inner sleeve, and an intermediate ball composed of a substantially soft compressible composite material.
Patent GB 230974 A utilizes Self - aligning bearings, such as that between a crank pin and tihe sleeve valve A of an internal combustion engine.
GB 330900 A describes self-aligning spherical joints or bearings. Patent WO 2016188526 A relates to a method for producing a spherical bearing, comprising an inner ring, which has a convexly curved spherical sliding surface, and an outer ring, which surrounds the inner ring.
The design of today's wheel hub bearings makes it difficult to preform condition monitoring.
An object of the present invention is to deal with the previously mentioned disadvantages.
A further object with the present invention is to provide a wheel hub bearing assembly suitable for high rotational speed.
It is a particular object of the present invention to provide a wheel hub bearing assembly that reduces friction.
A second particular object with the present invention is to provide a wheel hub bearing assembly where the different bearings rows can be condition monitored when the wheel hub is both in and out of service.
Short summary of the invention
This invention reduces friction, wear and tear through a wheel hub bearing assembly comprising inner and outer wheel hub bearing members wherein the wheel hub mearing members are rotatable with respect to each other. This yields a reduced relative motion at the bearing interface. This leads to an extended service life, a reduction in friction and enables higher rotational speeds.
An object of the present invention is to deal with the previously mentioned disadvantages.
It is a particular object of the present invention to provide a wheel hub bearing assembly with improved friction, wear and tear properties and an extended service life.
The invention is a wheel hub bearing comprising:
- at least one inner wheel hub bearing member (510), and
- at least one outer wheel hub bearing member (501), wherein said inner wheel hub bearing member is arranged to be fixed to a shaft, wherein the wheel hub bearing comprises a first intermediate wheel bearing hub member (509) that is radially stacked between the inner and outer wheel hub bearing members (510, 501), wherein the first intermediate wheel hub bearing member (509) is rotatable relative the inner and outer wheel hub bearing members.
Figure captions
An illustrative and non-limiting embodiment of the present invention will be described below in detail with reference to the appended drawings, in which:
Figures 1-5 illustrates the wheel hub bearing assembly comprising inner, outer and intermediate wheel hub members.
Embodiments of the invention
An embodiment of the invention illustrated by figure 1 is a partial cross section view of a wheel hub bearing assembly comprising inner 106, outer 102 and intermediate 104 wheel hub members to be used between a fixed body and a wheel, such as a bicycle fork and a bicycle wheel. The first inner wheel hub assembly member 102 is configured to be in contact with an inner row of rolling elements 105 and arranged to be fixed to a shaft. The intermediate bearing hub member 104 is radially stacked between an inner 105 and outer 103 row of rolling elements and rotatable relative the outer and inner bearing hub members. The outer bearing hub member 102 is in contact with outer row of rolling elements 103 and the wheel hub member in contact with the wheel. The inner and outer rows of rotating elements should have a substantially common frictional moment so that the circumferential speeds of the rows of rotating elements are substantially the same. If the frictional moment increases from the inner to the outer rows of rotating elements the circumferential speed decreases from the inner to the outer rotating elements.
An embodiment of the invention illustrated by figure 2 is a partial cross section view of a wheel hub bearing assembly comprising inner 205, outer 201 and intermediate 203 wheel hub members to be used between a fixed body rotating body, such as a railroad wheel axle and a railway axle box. The first inner wheel hub assembly member 205 is configured to be in contact with a double inner row of rolling elements 204 and 206.The inner wheel hub member is arranged to be fixed to an axle. The intermediate bearing hub member 203 is radially stacked between a double inner row 204 and 206 and a double outer row 202 and 207 of rolling elements. The intermediate bearing hub member is rotatable relative the outer and inner bearing hub members. The outer bearing hub member 201 is in contact with double outer row of rolling elements 202 and 207 and the wheel hub member in contact with the railway axle box.
There are different configurations of the wheel hub bearing, in one configuration the inner ring rotates and the outer ring is fixed. In the other configuration, the outer ring is rotating and the inner is fixed.
The inner and outer rows of rotating elements should have a substantially common frictional moment so the circumferential speeds of the rows of rotating elements are substantially the same. If the frictional moment increases from the inner to the outer rows of rotating elements the circumferential speed decreases from the inner to the outer rotating elements.
An embodiment of the invention illustrated by figure 3 is a partial cross section view of a wheel hub bearing assembly comprising inner 308, outer 302 and intermediate 305 and 309 wheel hub members to be used between a fixed body rotating body, such as a vehicle wheel axle and a suspension. The first inner wheel hub assembly member 308 is configured to be in contact with a double inner row of rolling elements 306 and 307.The inner wheel hub member is arranged to be fixed to an axle. The intermediate bearing hub member 305 and 309 is radially stacked between a double inner row 306 and 307 and a double outer row 303 and 304 of rolling elements. The intermediate bearing hub member is rotatable relative the outer and inner bearing hub members. The outer bearing hub member 302 is in contact with double outer row of rolling elements 303 and 304 and the wheel hub member in contact with the vehicle suspension.
There are different configurations of the wheel hub bearing, in one configuration the inner ring rotates and the outer ring is fixed. In the other configuration, the outer ring is rotating and the inner is fixed.
The inner and outer rows of rotating elements should have a substantially common frictional moment so the circumferential speeds of the rows of rotating elements are substantially the same. If the frictional moment increases from the inner to the outer rows of rotating elements the circumferential speed decreases from the inner to the outer rotating elements.
An embodiment of the invention illustrated by figure 4 is similar to the embodiment illustrated in figure 3 with the exception that the rotating elements are balls instead of rollers.
An embodiment of the invention illustrated by figure 5 is similar to figure 2 with plain bearings instead of roller bearings. The figure is a partial cross section view of a wheel hub bearing comprising inner 510, outer 501 and a multiple of intermediate 502-509 wheel hub bearing members to be used between a fixed body and a wheel. The first inner wheel hub bearing member 110 is configured to be in contact with the first intermediate wheel hub bearing member and arranged to be fixed to a shaft. The first intermediate wheel hub bearing member 509 is radially stacked between the inner wheel hub bearing member and a second intermediate wheel hub bearing member 508. The following (507-502) intermediate wheel hub bearing members are radially stacked between the second intermediate and outer wheel hub bearing members. The intermediate wheel hub bearing members are plain bearings and should have a substantially common frictional moment so that the circumferential speeds of the plain bearings are substantially the same. If the frictional moment increases from the first to the last of the plain bearing the circumferential speed decreases from the first to the last of the plain bearings.
It should be noted that the embodiments illustrated and described were given merely by way of non-limiting indicative examples and that modifications and variations are possible within the scope of the invention as defined by the appended claims. Thus, the invention applies not only to rollers but also other rotational elements, such as balls. It should also be easily understood that the rotating elements are kept separated by a cage and that the bearing hub comprises seals.
The described wheel hub bearing reduces friction, wear and tear by the use of a wheel hub bearing comprising inner and outer wheel hub bearing members wherein the wheel hub bearing members are rotatable with respect to each other. The wheel hub bearing further comprises a first intermediate wheel hub bearing member that is radially stacked between the inner and outer rotating elements and rotatable relative the inner and outer wheel hub bearing members. This results in a reduced relative motion between two adjacent wheel hub bearing members. This leads to an extended service life, a reduction in friction and enables a higher maximal speed. The definition parallel connected wheel hub bearing members means, that the wheel hub bearing has at least two wheel hub bearing members that are rotatable relative each other.
Parallel connected wheel hub bearing members:
The frictional moment (Equation 1) for n parallel connected wheel hub bearing members can be expressed by M (Eq.l):
111 1 — = — + — H— — (Equation 1) M M2 Mn n
As follows from Equation 1, the frictional moment is inversely proportional to the sum of the individual frictional moment components in a device with parallel connected wheel hub bearing members. Lowest frictional moment occurs when; Mi = M2 = Mn.
If one of the individual rotating wheel hub bearing members during use has higher friction than any of the others, it results in a lower relative speed for that individual wheel hub bearing member and higher relative speeds for the other individual rotating members. The friction loss will be substantially the same for all relatively individual rotating wheel hub bearing members (Eq.2).
