Description
Technical Field
The invention relates to a wheel module comprising a spur gear or traction mechanism drive driven wheel which is rotatably mounted on a bearing bolt via a coaxial radial bearing, wherein the radial bearing has at least one row of rollers which are held by a radial bearing cage, said rollers rolling on the radially inner side directly on the bearing bolt or on a separate bearing inner ring of the radial bearing which is arranged between the rollers and the bearing bolt, and said rollers rolling on the radially outer side directly on the wheel, i.e. within a hub bore introduced therein, or on a separate bearing outer ring which is arranged between the rollers and the wheel.
The field of application of the invention extends in particular to motor vehicle transmissions. In particular, the spur gear arrangement may comprise a wheel module consisting of a gear wheel and an associated bearing, which wheel module serves as a swivel wheel or intermediate wheel and is rotatably mounted as a driven wheel relative to a bearing bolt fixed relative thereto. The bearing bolt itself can be formed in a stationary manner in the transmission housing and also in a relatively movable manner with respect thereto, for example in the form of a planetary bolt of a planetary transmission. In addition, the driven wheels of the wheel module of interest here can also be designed as a v-belt or as a sprocket wheel, which can be a component of the traction mechanism drive.
Background
From DE 10002026 a1, a spur gear in the form of a change gear of a motor vehicle is known, which comprises a gear intermediate gear, which is rotatably mounted on a bearing bolt via coaxial radial bearings. The radial bearing comprises two rows of rollers which are held by a radial bearing cage which can be inserted together and which roll on the radially inner side directly on the respective associated raceways of the bearing bolts. Radially on the outside, the rollers of the radial bearing roll directly on the intermediate gear, i.e. on the respective associated raceways within the hub bore of the intermediate gear. The intermediate gear is axially guided from the adjacent housing toward one side and is provided with a separate starting disk toward the opposite side, which starting disk corresponds to a bearing cap provided in the transmission housing.
Said axial guidance of the intermediate gear therefore requires the starter disk to be mounted outside the bearing component and the guidance with respect to the opposite housing to be at risk of wear, at least when lightweight metals, such as aluminum, are used as housing material.
Disclosure of Invention
The invention is therefore based on the object of further developing a wheel module of the type mentioned above, which can be combined with axially adjacent lightweight metal components of the transmission in order to increase the service life in the region of the rotational bearing.
The object is achieved on the basis of the features of the wheel module according to the preamble of claim 1 in combination with its characterizing parts. Claim 10 is directed to a spur gear transmission or a traction mechanism transmission comprising a wheel module according to the invention. The respective dependent claims describe advantageous developments of the invention.
The invention comprises the technical teaching that the radial bearings of the wheel module are associated at both end sides with specific axial bearings for combined radial/axial support, the respective rollers of which, which are held by the axial bearing cage, roll on the outer rolling disks on one side and on the axial rolling surfaces which are formed in the region of the hub bore directly on the respective rim side of the wheel on the other side. The bearing inner ring has at least one groove-like, radially outer recess which interacts with a corresponding formation of the radially inner leg region of the associated rolling disk to form a snap connection. The radial bearing is formed by a cage and rollers, in particular two rows of rollers. The cage extends axially beyond the recess in the direction of the rolling disk.
In other words, the invention proposes a special axial support instead of an axial guide, which is sufficient with a small number of active components. The rolling disks which are respectively on the outside have sufficient raceway quality for the interaction with the rollers and, in contrast to the starter disk which lacks relative movement, do not cause wear-induced wear to adjoining components, so that the wheel module according to the invention can be used in conjunction with adjoining lightweight metal components of the transmission, for example the transmission housing, itself. In the case of the driven wheel to be supported, it is therefore possible to dispense with an additional rolling disk, since the wheel is finally made of a sufficiently wear-resistant material, for example a hardened steel alloy, and the axial rolling surfaces formed thereon can be produced in a simple manner with sufficient raceway quality, for example by grinding. The support is thus compact. The free installation space available in each of the interior of the bearing is fully utilized. The cage of the radial bearing, the side edges of which require axial installation space, is therefore arranged in such a way that the side edges of the cage project axially in the direction of the rolling disk of the axial bearing and in this case project beyond the recesses provided for the snap connection on the inner ring, so as to simultaneously surround radially between the snap connection and the respective axial cage of the respective axial bearing.
According to a measure improving the invention, it is proposed that the outer rolling disks each have a substantially U-shaped cross section in order to enclose the axial bearing cage and the radial bearing cage via the leg regions formed thereby. The cross section of the U-shape is understood here in such a way that only a rough envelope geometry should result in the U-shape. In addition to this, there may be additional formations, for example for retention purposes. The connection between the axial bearing cage and the radial bearing cage thus achieved forms a self-retaining structural unit which also enables simple mounting on the wheel module as a pre-mounted component.
In addition, the rolling disk can form a snap connection with the bearing pin or the bearing inner ring via the respective radially inner leg region. The preassembled structural unit can thereby be fixed to the wheel module by simple plug-in connection, and the clip connection furthermore forms an effective anti-loss protection for the rolling disk. Depending on the mounting sequence, a one-sided clip connection is also sufficient.
In order to achieve a snap connection, for example, the bearing inner ring can be provided with at least one radially outer groove-like recess, which is preferably designed as a circumferential groove and interacts with a corresponding design of the radially inner leg region of the associated rolling disk in order to form a snap connection. For this purpose, the radially inner leg region can have, for example, a nose-like profile or the like.
Optionally, the rolling disks can also form a snap connection together with the axial bearing cage via the respective radially outer leg region. For this purpose, the radially outer leg region can be provided, for example, with an inwardly bent edge region which surrounds the axial bearing cage.
According to a further development of the invention, it is provided that the bearing inner ring or the bearing pin, which is designed as a hollow pin, has at least two sections of different thickness, wherein at least one intermediate thickness section is designed to be wider than the two outer thickness sections. The targeted deviation of the inner bearing ring from a constant thickness design contributes to material savings and weight reduction. Furthermore, the thus formed larger outer diameter region of the bearing inner ring can be used as a sealing seat or the like.
It is proposed with respect to the intermediate-thickness section that it is arranged in the axial direction at least largely below at least one row of rollers of the radial bearing. Thereby, a stable support for the rollers can be maintained despite the above-mentioned material savings.
In addition, a circumferential groove-like lubricant duct with at least one connected radial bore can be introduced into the intermediate-thickness section for the lubricant supply of the combined radial/axial bearing. By such a central lubricant supply to the entire bearing region, the service life can be increased by means of the pressure lubrication to be connected thereto. The lubricant duct can be formed very flat for its function, so that the stability of the relatively thick section of intermediate thickness is not significantly impaired thereby.
According to a further refinement of the invention, it is provided that the radial bearing cage is guided in the axial direction between the two rolling disks. The solution with the functional integration makes it possible to dispense with an additional guide for the radial bearing cage.
According to a preferred embodiment, the radial bearing of the wheel module is designed as a double-row roller bearing or needle bearing, which is combined with two special end-side axial bearings.
Drawings
Further measures which improve the invention are indicated in detail below, jointly by the description of preferred embodiments of the invention, with the aid of the single figure. The figures show longitudinal sections through wheel modules with combined radial/axial support.
Detailed Description
According to the drawing, the wheel module is essentially formed by a driven wheel 1, in this case a gear wheel, which is rotatably mounted on a bearing pin, not shown in detail here, of the spur gear unit via a coaxial radial bearing 2. The radial bearing 2 is associated with an axial bearing 3a or 3b on both end sides in order to achieve a combined radial/axial support.
The combined radial/axial bearing 2 is a roller bearing and has two rows of rollers 5 arranged next to one another, which are held by a radial bearing cage 4. Each of the axial bearings 3a and 3b has a roller 7 held by an axial bearing cage 6.
With respect to the radial bearing 2, the rollers 5 roll on the radially inner side on a bearing inner ring 8, which is in turn fixed to a bearing pin, not shown in detail here. Radially on the outside, the rollers 5 of the radial bearing 2 roll on the hub bore of the wheel 1, so that a separate bearing outer ring is eliminated here.
With regard to the axial bearings 3a and 3b, the respective rollers 7 each roll on one side on an outer rolling disk 9a or 9 b. On the wheel side, the rollers 7 roll on axial rolling surfaces 10a and 10b, respectively, which are formed on the rim side of the wheel 1.
The outer rolling disks 9a and 9b each have a substantially U-shaped cross section, the leg regions of which comprise, in the manner shown, the respective axial bearing cage 6 together with the radial bearing cage 4 in order to connect them to form a held-together assembly.
Here, the U-shaped rolling disks 9a and 9b are releasably snapped onto the component for anti-loss protection. Furthermore, the radially inner leg regions of the two rolling disks 9a and 9b together with the bearing ring 8 form a further snap connection, so that the bearing inner ring 8 and the rolling disks 9a or 9b, the two axial bearing cages 6 and the radial bearing cage 4 are positioned in a fixed position relative to one another. In contrast, the rollers 5 of the radial bearing 2 enclosed by them and the rollers 7 of the two axial bearings 3a and 3b can be moved in rotation to fulfill the rolling bearing function. For this purpose, the bearing inner ring 8 is provided with a plurality of groove-like recesses 11 (as an example) which interact with corresponding radially outwardly directed formations of the respective rolling disk 9a or 9 b.
The inner bearing ring 8 of the rolling bearing 2 has two different thickness sections, wherein the middle thickness section 12 is thicker in material thickness than the two outer, thinner thickness sections 13a and 13 b. The intermediate-thickness portion 12 extends in the axial direction largely below the two rows of rollers 5 of the radial bearing 2 in order to ensure a stable rolling bearing.
Furthermore, the intermediate-thickness section 12 of the bearing inner ring 8 is provided with a flat, circumferential lubricant channel 14, which does not impair the stability, from which the radial bores 15 start in order to supply the combined radial/axial bearing with lubricant, which is delivered by a conventional, not further shown here, pressure-oil lubrication circuit.
The invention is not limited to the preferred embodiments described above. Rather, variants thereof are also conceivable which are encompassed by the scope of protection of the following claims. For example, it is also possible for the wheel 1 of the wheel module not to be designed as a gear wheel of a spur gear or the like, but rather as a triangle pulley or a sprocket wheel of a traction mechanism transmission. Furthermore, the radial bearing 2 and the axial bearings 3a and 3b can be formed as other rolling bodies, as long as they ensure the bearing function required here. The rolling disks 9a and 9b arranged on the outside on the axial bearings 3a and 3b should preferably be formed from hardened steel sheet, for example as punched and bent parts, in order to fulfill the usual function.
