- the camshaft consists in this area of an outer shaft 1 and a Concentric in this mounted inner shaft 2. Slid on the outer shaft 1 and firmly connected to this example by a shrink fit, a bearing ring 3, via which the camshaft is rotatably mounted in ' a stationary abutment 4.
- adjustable camshafts of an internal combustion engine of a motor vehicle.
- adjustable camshafts are located on the outer shaft 1 each firmly connected to this first cam.
- Second cams are fixedly connected to the inner shaft 2 in a rotatable mounting on the outer shaft 1.
- the fixed connection between the second cam and the inner shaft 2 takes place through recesses in the outer shaft 1 therethrough.
- This adjusting device 5 comprises two relatively mutually rotatable adjusting elements, namely a first adjusting element 6 and a second adjusting element 7.
- first adjusting element 6 with the bearing ring 3 and the second adjusting element 7 with the inner shaft 2 are respectively firmly connected.
- the connection is such that in both control elements 6, 7 is a contact with an end-side end portion of the inner shaft 2, the outer shaft 1 and the fixedly connected to this bearing ring 3 is given.
- end face connecting surfaces which are defined together as the connecting surface 8.
- feed channels 9 to 12 To supply the hydraulic adjusting device 5 a total of four feed channels 9 to 12 are provided in the illustrated embodiment.
- the areas of these feed channels 9 to 12, which are located outside of the adjusting device 5, are each indicated without a dashed index, while the portions which are located within the actuator, each with a bleed index are occupied.
- the number of feed channels 9 to 12 depends on the structure and the function that an adjusting device 5 is to exercise.
- Four feed channels 9 to 12 are required in particular in known embodiments of adjusting devices 5, if in addition to a relative movement between the inner and outer shaft 2, 1 and the entirety of both shafts 1, 2 against a stationary storage should be adjustable in angle.
- the feed channel 9 extends outside of the adjusting device 5 exclusively in the bearing ring 3 and communicates from there
- the feed channel 9 opens at one end axially parallel to the camshaft into the connecting surface 8 and at the other end radially into an annular channel 9 '' in the outer circumferential surface of the container Bearing ring 3.
- the production of this feed channel 9 takes place by intersecting blind holes from one side of the connecting surface 8 and on the other hand from the annular channel 9 '' starting.
- the annular channel 9 "is supplied with hydraulic fluid from an inlet channel 9"'associated with the abutment 4, that is to say here with lubricating oil under pressure in the described embodiment.
- the supply of lubricating oil to this feed channel 10 takes place in the same way as that described above Feed channel 9.
- the feed channel 10 is not composed of blind hole bores crossing within the bearing ring 3. Rather, the feed channel 10 consists of a radial bore, which passes through the entire radial thickness of the bearing ring 3 and a radial annular gap 10 IV between the outer shaft 1 and the bearing ring 4.
- the annular gap 10 IV is on the connecting surface 8 and through it within the encryption Setting device 5 a Zuzhoukanal 10 'fluid communicating associated. Through the annular gap 10 IV , the bearing ring 3 sits firmly on the outer shaft 1 exclusively via its axially adjacent this annular gap 10 IV area.
- the feed channel 11 is similar in construction and course to the feed channel 10 described above. Also, this feed channel 11 opens via an annular channel 11 IV in an associated feed channel 11 'on the connecting surface 8 away in the adjusting device 5 inside. To connect the annular channel 11 IV to the radially extending region of the feed channel 11, a radial bore 11 v guided through the outer shaft 1 is used.
- the feed channel 12 has, like the feed channel 11 within the bearing ring 3, a radial bore which opens into an intersecting blind hole bore within the inner shaft 2 via an associated radial through hole 12 V of the outer shaft 1.
- the axially extending region of these blind bores of the feed channel 12 opens via the connection surface 8 into a corresponding feed channel 12 'within the setting device 5.
- the inner shaft 2 can be provided up to its axial end within the camshaft with a large outer diameter, whereby a good torsional rigidity is obtained.
- a plurality of feed channels can be provided, each of which can be controlled individually. The arrangement of the feed channels in particular enables an axial force-free row of hydraulic fluid supply to the actuating device 5.
- the difference in the design of the feed channel 209 results exclusively from a different design of the associated end portion of the camshaft, in which the inner shaft 2 extends axially beyond the associated end of the outer shaft 1 on the one hand axially and on the other hand diameter-stepped to a section with a smaller diameter.
- the axial from one to the Ring channel 109 '' axially adjacent annular channel 209 '' must be supplied, space-related with respect to its radial course within the bearing ring 3 relative to the respective region of the feed channel 109 are circumferentially offset. Furthermore, the radial portion of this feed channel 209 must be passed through the outer shaft 1. In this case, the radial region of the feed channel 209 can open into an annular channel 13, which is formed by the diametrically reduced end portion of the inner shaft 2.
- this embodiment is also suitable for more than two feed channels, that is to say in particular for four feed channels according to the embodiment in FIG. 1.
- the difference compared to the embodiment of FIG. 2, in which also only two feed channels are drawn and described, consists merely in that in the embodiment of FIG. 3 a radially split bearing ring 3 is ⁇ sets, which consists of an inner ring portion 3 'and an outer deferred outer ring 3''.
- the outer ring 3 '' can be shrunk onto the inner bearing ring 3 ', for example, whereby a firm connection is created between the two bearing ring parts 3', 3 ''.
- the feed channel 409 Due to the division of the bearing ring 3 into an inner region 3 'and an outer ring 3'', the feed channel 409, which is axially further away from the end of the camshaft than the feed channel 309, can be deflected within the inner bearing ring region 3' such that the feed channel 409 can be performed together with the other feed channel 309 in the radially inner region of the bearing ring outside the outer shaft 1, that is, that the outer shaft 1 need not be radially excluded. How this is possible in terms of production is shown in section f of FIG. 3 quite clearly recognizable angular course of Zu Industriesbohrung 409. Such an angular course can be in a split bearing ring 3 ', 3 "" extremely easy to produce, but not in a one-piece bearing ring. 3
- the outer bearing ring 3 '' and the inner bearing ring 3 ' may be made of different materials and that in each case adapted to the requirements placed on these areas. So can for example, the outer bearing ring 3 '' made of tribologically particularly suitable material, while the inner bearing ring portion 3 'can be formed of high strength material to absorb the driving forces and transmitted.
- the feed channels can be executed milled in a split bearing ring design, at least in some areas, which can be compared to purely drilled feed channels easier to produce direction-changing courses. In particular, a large number of small holes can be combined to form a necessary larger flow cross-section, if a larger diameter hole can not be realized in terms of space.
- the bearing ring 3 may be finished prior to assembly on a camshaft, that is, the outer shaft 1, which has a positive effect on the manufacturing time, cost and quality.
- This drawn embodiment illustrates how 3 milled oil supply cross-sections can be realized in a radially divided bearing ring and that by the example of the feed channel 409 in FIG. Third
- bearing ring designs which are described in detail below, are those which can be used particularly advantageously in the context of the present invention. Basically, these are, however, gerringaus entryen that can be used anywhere regardless of an adjustable camshaft according to the present invention in such cases in which liquid from lying on the outer circumference of a bearing ring ring channels through the bearing ring is to be performed at axially adjacent ring channels and a possible axially short Training of the bearing ring.
- a bearing ring 30 has on its outer circumference axially adjacent annular channels 31, the functionally correspond to the annular channels 9 ", 10", 11 “and 12" in the embodiment of the bearing ring 3 of FIG. 1.
- radial bores 32 lead into the inner circumferential surface of the bearing ring 30.
- Individual of the annular channels 31 contain sealing rings 33, of which in each case one abuts one of the two axial flanks of these annular channels 31.
- the sealing rings 33 provide for a bearing of the bearing ring 30 in an abutment in, for example, an embodiment according to that of the abutment 4 in FIG. 1 for a mutually dense delimitation of the annular channels 31.
- By the above-described arrangement of the sealing rings 33 can at a plurality of axially adjacent annular channels 31 an axially short construction of the bearing ring 30 can be achieved.
- axially adjacent annular channels 31 may be located axially between these annular channels 31, a further annular channel 31, which in itself is not lined with sealing rings 33.
- the adjacent sealing rings 33 take over the function of axial boundary walls for the sealing ring-free annular channel 31st
- this bearing ring design has, in principle, one with that of FIG. 5 matching alternative on.
- the alternative consists exclusively in that for stabilizing the position of the sealing rings 33 on the adjacent groove flanks of the annular channels 31, no anchors 34 fixed in the base of these annular channels 31 are provided.
- the position assurance takes place here rather by retaining means which are integrated in the sealing rings 33 themselves.
- These holding means can be of various types and basically only serve to secure the sealing rings 33 in their position on the side flanks of the annular channels 31, without obstructing a fluid flow through the respective annular channels 31 excessively.
- the exploded view in Figure section b shows two sealing rings 33, which are combined to form a so-called tandem ring.
- the bearing ring according to this embodiment has an outer circumference with a constant diameter. In this outer wall open the radial bores 32 of the bearing ring 30th
- the annular channels 31 are formed by sealing rings 33, which in each case have a radial axis between them. Ie bore 32 are inserted into receiving grooves in the outer wall region of the bearing ring 30 in a form-fitting manner. Since these sealing rings 33 are in each case journalled over practically the entire circumference of the bearing ring 30 in continuous bearing ring material and only directly or indirectly adjoin the radial bores 32, an axially short design of the respective bearing ring 30 can also be achieved here.
- the bearing rings can be outwardly exciting, circumferentially slotted rings in the nature of piston rings and made of metal or plastic.
- closed sealing rings made of elastically extensible material. These may have the cross-section of about an H.
- the upstanding legs serve as sealing rings 33 of a sealing ring tandem and the central web as a spacer.
- the middle bar must of course be provided with flow openings.
