Disadvantageously, because materials'use is a lot, the rotor of this structural type quite weighs, and due to the process step for introducing needed for pressure medium channel, such as, holes, and expends very much in the mill.
Summary of the invention
Task of the present invention is, the rotor of type described in a kind of introductory song is described, this rotor can as far as possible gently and manufacture as far as possible simply.In addition, the corresponding light of type described in a kind of introductory song is it also illustrated and the camshaft adjuster that can simply manufacture.
For the wheel hub had for holding camshaft there is the rotor of the overcoat being with some blade elements, wherein, pressure medium channel extends from the inner space of wheel hub to overcoat, first mentioning of task solves in the following way according to the present invention, namely, at least one pressure medium channel is interrupted by axial material recess, and wherein, the sleeve pipe of the pressure medium channel of disconnecting is inserted in this material recess.
At this, the present invention is first from following consideration: the region without supporting functions or sealing function can be vacated or hollowed out in principle on rotor.But the present invention recognizes in addition surprisingly, especially the region of pressure medium channel can be hollowed out, although make pressure chamber substantially interrupt to the connection in hydraulic system thus.Again set up by the sleeve pipe inserted with method in a straightforward manner because the flow technique hollowing out the pressure medium channel interrupted due to the material recess introduced in other words connects.
Compared to structural type up to now, rotor can be produced with obvious less weight by the material recess in a pressure medium channel region or in multiple pressure medium channel of not paying attention to up to now.The connection of the pressure medium channel interrupted by material recess is realized by being inserted into simply in unlimited material recess by corresponding sleeve pipe.This sleeve pipe especially can by being made of plastics without the molding mode cut.Such as, but by metal, it is also feasible for being manufactured by aluminium.
Connect in order to reliable flow technique and in order to fairly simple sealing, the inner diameter of sleeve pipe be chosen as the diameter being greater than the pressure medium channel docked respectively.Also sleeve pipe is made to become easy to the insertion in material recess thus, this is because the deviation of concentricity in particular range of sleeve pipe and the pressure medium channel docked inserted can be tolerated by this measure.Advantageously, sleeve pipe has positive element, installation that is that the shape acting in conjunction of these positive elements and epitrochanterian complementation only allows precise match or angular orientation.
According to preferred embodiment, the sealing function of the sleeve pipe of cross-over connection material recess is guaranteed in the following way, that is, sleeve pipe inserts under the press fit about pressure medium channel axis.If sleeve pipe is made up of the suitable plastics become that can flow, so thus achieve enough for the lasting sealing function of camshaft adjuster.If sleeve pipe is made up of fibre-reinforced plastics, so preferably select following material, it has the thermal expansion coefficient similar to the material of rotor.Such as, for rotor made of aluminum, the epoxy resin of glass fiber reinforcement can be used as the material of sleeve pipe.
In order to avoid imbalance, preferably material recess is incorporated in rotor in the mode of rotation-symmetric.Especially can arrange the material recess of multiple ring segment shape, the material recess of these ring segment shapes interrupts multiple pressure medium channel respectively.In favourable embodiment, material recess is substantially as providing the annular chamber that multiple pressure medium channel interrupts between wheel hub and overcoat, and wherein, the pressure medium channel interrupted to connect each respectively inserts a sleeve pipe.By this design proposal, the significant weight saving of rotor can be realized.At this, in order to the assembling of the simple angular orientation of sleeve pipe, aptly annular chamber is interrupted by least one radial contact pin.This contact pin is that the collar tube sub-assembly be inserted into provides backstop, installs thus and only can carry out in other words in the Angle Position limited precise match.Alternatively, in order to the assembling of the angular orientation of sleeve pipe, ridge or groove can be arranged in annular chamber, especially on periphery or on bottom.
Desirably, when the material recess of ring segment shape or annular cavity-like, on be arranged in by described or each sleeve pipe ring segment shape or annular inserting member, this inserting member is inserted in material recess.In such an implementation, especially all sleeve pipes are incorporated on unique inserting member, are inserted in material recess to assemble this inserting member is if desired in backstop to mentioned contact pin.At this, especially axial stop is formed on the bottom of rotor.By positive element or the installation of angular orientation carrying out inserting member given in advance especially by radial contact pin.
In the design proposal that another is favourable, inserting member comprises some axial bumps, thus the inserting member of insertion axially height is flushed with overcoat.Thus, ensure that in the mounted state and be arranged in sleeve pipe on inserting member and each pressure medium channel to be connected is arranged on an axial plane.Inserting member remains between the cover plate of camshaft adjuster, especially between the bottom of rotor and the locking cover plate of stator by its axial bump.Axial bump can be arranged on the side of inserting member.But axial bump also can alternately extend in circumferential direction on one and another axial side.
Advantageously, described or each sleeve pipe is arranged on an axial bump.This allow with the least possible material and thus easily design especially inserting member by the sleeve pipe matrix that connects of axial bump in other words.If axially staggered each other in the rotor for the pressure medium channel shifting to an earlier date conditioning chamber and delayed conditioning chamber, so following embodiment is preferred, in this embodiment, axial bump alternately extends in circumferential direction on one and another axial side, wherein, sleeve pipe for supplying conditioning chamber is in advance arranged in an axial bump, and the sleeve pipe for supplying delayed conditioning chamber is arranged in another axial bump.
Inserting member can be made single type or multi-part type.Inserting member especially can be made of plastics with without the mode of cutting.With metal, such as by sintering process without cut manufacture also be feasible.
In independently creative design proposal, the rotor of type described in introductory song comprises the ' locked ' zone of the boring had for holding movable stop door bolt, in order to the weight saving of this rotor specifies, this boring is all hollowed out except the axial wall region on bore entrance, wherein, to stop door bolt carry out against supporting supporting member opposed with bore entrance be inserted in the region hollowed out.
This design proposal of rotor can not rely on the characteristically enforcement of the pressure medium channel in rotor.At this, the present invention is from following consideration: because will meet the lockable with the machinery of stator, so epitrochanterian ' locked ' zone is relevant to the larger mass accumulation caused by the materials'use increased.When engine shutdown, such ' locked ' zone can realize rotor is locked with the Angle Position limited to each other relative to stator.Thus, ensure that when engine starting rotor can not move uncontrollably owing to not yet producing enough pressure in hydraulic system and may clash into the dividing element of stator, this can cause the less desirable noise explicitly of camshaft adjuster.
This independently creative solution also from following consideration: mass accumulation relatively large in ' locked ' zone can cause the imbalance of rotor to increase.Epitrochanterian ' locked ' zone arrange from rotation axis more away from, this imbalance is larger.But, the uneven wearing and tearing adversely causing the less desirable overburdening of bearing also therefore to cause the raising of camshaft adjuster.In addition, and also it is desirable that, subtract trochantinian weight on the whole.
As solution, the present invention specifies astoundingly, hollows out the boring for holding stop door bolt to the full extent, thus makes on bore entrance, only retain thinner wall region.The support for stop door bolt born by foot of hole up to now and supporting functions are fulfiled by the supporting member opposed with bore entrance.This supporting member can be configured to independent component and be inserted in the region hollowed out.But this supporting member also can be fabricated to a part for rotor and therefore be connected directly between on the edge in the region hollowed out.
