Description

Stator for camshaft adjuster with force receiving component formed thereon

The invention relates to a stator for a camshaft phaser of the vane type, comprising a stator base member and a stator base member on the outer side and fixed thereto for torque transmission force receiving member, wherein the force receiving member and the stator base are made of different materials, and wherein the force receiving member for torque absorption is prepared by a continuous drawing means, such as a chain or a belt.

Gas exchange valves of internal combustion engines can be actuated by cams of a camshaft. About the arrangement and shape of the cam, the opening and closing times of the gas exchange valves are specifically defined. The camshaft is usually actuated, driven and / or driven by the crankshaft of the internal combustion engine. The opening and closing times of the gas exchange valves of the internal combustion engine are usually specified by a relative rotational position or phase position or angular position between the cams and the crankshaft. By a relative change of this relative rotational position between the camshaft and the crankshaft, a variable adjustment of the opening and closing times of the gas exchange valves can be achieved. Due to the variable adjustment of the opening and closing times of the gas exchange valves, depending on the current operating state of the internal combustion engine, for example, the exhaust behavior can be positively influenced, the fuel consumption can be reduced, the efficiency can be increased, and / or the maximum torque and / or the maximum power of the internal combustion engine can be increased.

This variable adjustment of the opening and closing times of the gas exchange valves can be provided by a between the crankshaft and the camshaft hene camshaft adjusting device or device or such a camshaft adjuster be made or made possible.

For this purpose, usually a camshaft adjuster is provided between the crankshaft and the camshaft. A part of the camshaft adjuster, hereinafter referred to as stator, is rotatably connected to the crankshaft. Another part of the camshaft adjuster, hereinafter referred to as rotor, is rotatably connected to the camshaft. A gear is conventionally provided between the stator and the rotor. This gearbox is conventionally provided as a hydraulically actuated vane cell, or as a plurality of such vane cells, in a vane-type hydraulic camshaft phaser. By applying the vane with hydraulic pressure, the variable adjustment of the opening and closing times of the gas exchange valves can be achieved. This refinement may also be referred to as a rotary piston adjuster. It should be noted at this point, however, that the present invention is not limited to camshaft adjuster of the vane type, but in principle can be found in camshaft adjusters of a different type application. The crankshaft is connected to the stator usually by means of a continuous drawing means. This endless traction means transmits a rotary power driving the camshafts or a torque to the force receiving member. The present invention is concerned with the connection of the force receiving member to the stator.

A stator of the type mentioned is known for example from DE 101 43 862 A1. This describes a camshaft adjuster with a stator, a rotor and two axial side covers. The camshaft adjuster is used to change the timing of gas exchange valves of an internal combustion engine, and the stator is in drive connection with a crankshaft of the internal combustion engine, while the rotor is connected to a camshaft of the internal combustion engine. The stator and the axial side cover form a one-piece Stator unit. The stator unit may be an aluminum or magnesium die casting or a plastic injection molded part. A separate chain or belt ring made of steel may be attached to the stator unit.

For example, from DE 102 1 1 607 A1 further stators are known. One of them has a toothed belt wheel, which is made in one piece with a hood-shaped cover made of a heavy-duty plastic. In this cover is a

Stator main component made of a conventional material inserted and screwed to it. Another stator is formed integrally from the heavy-duty plastic and has the toothed belt wheel, the hood-shaped cover, a closing ring and the stator main component. As a highly resilient plastic while a material is proposed, which preferably has about 20% resin, about 20% glass fibers and about 60% minerals.

Bolting the force receiving member to the stator base member has the disadvantages of incurring additional costs for the material, manufacturing and assembly, and subjecting the bolted connection to a decrease in the strength of the threaded fastener during the life of the stator. The same applies to a fastening of a separate chain or belt ring made of steel. Furthermore, an assembly of a stator main component, equivalent to a Statorgrundbauteil, and other stator components, which are in contact with the vane, the disadvantage that for sealing the vane constructive effort is necessary, for example, even after a set of the materials involved leakage to avoid.

The present invention has the object to avoid the disadvantages mentioned and generally to improve the known stators. More specifically, a stator according to the invention should be inexpensive to produce, have a low weight, have a low rotational inertial mass, be easy to assemble, be tight, chemically resistant, be thermally stable, with the forces and torques without fatigue are permanently stressed that can occur transmit forces and torques, allow a combination of different materials and / or manufacturing technologies, and / or be suitable for use in the engine compartment of a motor vehicle.

This object is achieved in a generic stator according to the invention that on the outside of Statorgrundbauteils a prepared for Axialkraft- and / or torque absorption of the force receiving member outer contour is formed. This outer contour makes it possible to inexpensively connect the basic stator component with the force receiving component because of a possible omission of further fastening means, such as screws. This outer contour also allows a combination of different materials and / or production technologies for the stature basic component and the force receiving member.

If the outer contour is integrally formed on the outside of the basic stator component, this makes it possible in a particularly simple manner to produce the stator base component with the outer contour without further manufacturing steps.

Advantageous developments are claimed in the subclaims and are explained below.

Thus, it can be provided that one of the components of stator basic component and force receiving component made of plastic and the other is formed of metal. This enables the advantages of a metal, such as high strength, high thermal conductivity, and a variety of known low cost machining processes, with the advantages of a plastic, such as a variety of low cost manufacturing processes, light weight, electrical capability Isolation, a high damping effect or the like to combine. In particular, aluminum alloys, iron alloys, such as steels, and / or magnesium alloys should be considered as metallic materials. As plastics, all polymers, thermosets and, in particular, all matrix materials or composite materials should be used such as fiber composites be considered. By a suitable choice of the materials or the material combination can be achieved in particular a chemical resistance, thermal resistance, a particular suitability for transmitting the forces and torques, a special fatigue strength, and / or a particular suitability for an application in the engine compartment of a motor vehicle ,

If the force receiving member is integrally formed on the stator base member and / or cohesively, this ensures a particularly firm connection of stator base member and force receiving member. At the same time it is possible to dispense with any further attachment of the two components together.

As the basic stator component, in particular a vane cells defining

Statorhauptbauteil or the vane axial closing stator cover be thought. These two parts are conventionally separated for mounting a vane type camshaft phaser to mount a rotor in the stator base. Therefore, if one of these two components used as Statorgrundbauteil, can be dispensed with an intermediate part and a high density can be achieved. It should be noted at this point that the vane type is merely a preferred type of camshaft adjuster. The term "wing cell" can be replaced by the term "working space". For example, in a camshaft adjuster of an electrically operated type, in the working space of the electric drive, such as an electric motor and / or a transmission may be provided.

The outer contour may extend with prismatic cross section in the longitudinal direction of the stator base member. The longitudinal axis is the axis about which the camshaft adjuster is designed substantially rotationally symmetrical. Thus, by means of the prismatic cross-section in the longitudinal direction, an outer contour cooperating in a circumferential direction with the force-receiving component in a circumferential direction can be achieved. This allows a force and / or torque absorption of the force receiving member are designed to be particularly resilient on the stator base. Instead of the term "prismatic cross section", the term "polygonal cross section" can also be used. In this case, a multiplicity of prismatic cross sections arranged in the circumferential direction of the stator basic component can also be considered. It is particularly preferred if the same cross section repeats in the circumferential direction, because this results in a behavior which is approximately homogeneous in the circumferential direction, for example with respect to force and torque transmission.

It can be provided that the outer contour is at least two parts, wherein a first part of the outer contour at one axial end of the stator base member relative to another part of the outer contour at the other axial end of the

Statorgrundbauteils is offset by a predetermined angle in the circumferential direction. Thus, a positive connection between the force receiving member and the Statorgrundbauteil be achieved in the axial direction, so that slipping of the stator base member relative to the force receiving member is reliably prevented.

It can be provided that the outer contour is formed as a circumferential ridge. Thus, a positive connection between the force receiving member and the Statorgrundbauteil is achieved in the axial direction with simple means. If that for the

Statorgrundbauteil used material has a higher density than the material used for the force receiving member, it is for the purpose of lighter weight and less rotational inertia advantage if the web is designed partially circumferential. It is preferred for avoiding an imbalance when the bridge is designed to be symmetrical interrupted circumferentially.

If the outer contour has a Entformungsschräge, wherein the Entformungsschräge is tapered towards an axial end of the stator base or to both axial ends of the stator base, a clamping of the outer contour can be avoided in a production tool especially in urformend educated outer contour. It is preferred if the Entformungsschräge less than 10 °, more preferably less than 5 °, even more preferably less than 4 °, and most preferably between 2 ° and 4 °.

In order to prevent a (local) lifting of the force receiving component of the stator base member, it can be provided that the outer contour forms a distinction in the radial direction of the stator main body. An example may be a T-shaped web comparable to an I-beam, a web which has the shape of an inverted "L", and / or a prismatic cross-section in the manner of a dovetail groove.

The outer contour can thus, for example, a longitudinal direction of the

Statorgrundbauteils extending prismatic or polygonal cross section or be an at least partially circumferential ridge. The outer contour can also be a multiplicity of different prismatic / polygonal cross sections, which, for example, increase and / or decrease in the longitudinal direction in the manner of a staircase / step. The outer contour can also have several webs. The outer contour can also be any combination thereof.

The outer contour may have an axially oriented through hole and / or an axially oriented recess and / or a radially oriented recess and / or a combination thereof. In this case, a variety of different and / or similar such designs should be considered. Particularly preferred these designs are provided on a web. The same is also possible with other outer contours, such as the prismatic cross section. These outer contour configurations all have the advantage that they preferably represent at least one positive locking in the circumferential direction. However, it is also clear, for example on the basis of the axially oriented through-hole, that these outer contour configurations also enable a positive connection in the radial direction, so that a (local) lifting of the force receiving component from the stator base component can be prevented in an advantageous manner. The End loszug means may be a chain or a belt, such as a flat belt, a V-belt, a toothed belt or the like. The endless draw means may be dry-running, wet-running (eg, "belt in oil" construction) or lubricated The force-receiving member may be suitably referred to as a sprocket or as a pulley.

In other words, the invention has, inter alia, to reduce the objectives of the stator and thus in the entire camshaft adjuster the mass and inertia, spare items such as screws, and assembly costs, by a suitable connection method of Statorgrundbauteil and force receiving member Advantages of known manufacturing methods to combine to save by the connection method itself at least one assembly step and / or to avoid setting the material of the force receiving member at high voltages by the connection method. In an embodiment according to the invention, a component of the camshaft adjuster (camshaft adjuster component) is "overmolded", which preferably, but not exclusively, engages

Statorgrundbauteil or a (stator) cover is. It should be achieved by a suitable configuration of the outer contour / the connection geometry of the surfaces in contact, such as an outer surface of the stator base member and an inner surface of the force receiving member, that this compound can absorb axial forces and camshaft or drive torque, and that the camshaft Verstellerbauteil is structurally stiffened, so that a small deformation of the component, in particular in the radial direction, occurs, so that a relative movement between the Statorgrundbauteil and the force receiving member is reduced or avoided.

The figures are merely schematic in nature and are only for the understanding of the invention. Identical elements or comparable elements are provided with the same reference symbols and can be interchanged with one another. So they are interchangeable.

A first embodiment of the invention will be described with reference to FIGS. 1 to 2 described. Shown is a stator 1, more precisely, a stator base 2 of the stator. 1 The basic stator component 2 is essentially rotationally symmetrical with respect to a longitudinal axis L. The longitudinal axis L defines a radial orientation R and an orientation U in a circumferential direction.

Radial outside of the stator base 2 is an outer surface 3. Radially inside of the stator base 2 defines this a working space 4 for a wing cell (not shown). In the axial direction, the basic stator component 2 is bounded in each case by an end face 5, the end faces 5 each represent an axial end or an axial end side of the main stator component 2.

On the outer surface 3, an outer contour 6 is formed. The outer contour 6 is also referred to as connection geometry. The outer contour 6 serves to transmit axial forces and / or torques between the basic stator component 2 and a force receiving component (not shown). In the first embodiment, the outer contour 6 has the shape of a plurality of prismatic cross-sections 7. th embodiment, the prismatic cross section 7 is a triangle. The prismatic cross-section 7 is shown in dashed lines in Fig. 2. The individual prismatic cross-sections 7 each extend along the longitudinal axis L. A single prism 8 thus has the shape of a roof 9. In the first embodiment, the prisms 8 are arranged directly next to each other, so that the outer contour 6 is generally similar to a toothing.

The Statorgrundbauteil 2 is formed from steel. This is preferred

Stator basic component sintered. In this case, the outer contour 6 has been formed primitive. In a second production step, the force receiving component is formed on the outer contour 6. Preferably, the force receiving member is made of plastic and is preferably formed by means of an injection molding process or a core embossing process priming the formed outer contour 6. It is particularly preferred if the outer contour 6 is already formed ready for operation, that is already sintered, hardened or the like, before the force receiving member is formed on the outer contour 6. It can also be said that the basic stator component 2 is "overmolding" the force-receiving component Thus, the force-receiving component is formed on its radially inner inner surface complementary to the outer surface 3 of the stator main component 2. A radially outer surface of the force-receiving component is for receiving an axial force and / or a torque of a endless traction means (not shown) is formed.

By dividing the stator 1 into the basic stator component 2 made of metal and the force receiving component made of polymer, a reduced weight and a reduced rotational inertia are achieved. In particular, the design of a radially outer lower density (plastic or polymer) than the radially inner density (metal), a particularly reduced rotational inertia of the stator 1 is achieved around the longitudinal axis L. The hereby used for the prototyping of the stator main component 2 and the force receiving component manufacturing techniques, namely sintering and injection molding or core embossing, make it possible, with only a small Finishing effort to obtain the finished stator 1, since both manufacturing techniques allow complex three-dimensional shapes.

In a further development, it can be provided in the first embodiment that the outer contour 6 is slightly beveled along the longitudinal axis L and thus a

Entformungsschräge (not shown). Most preferred is one

Entformungsschräge which is inclined to a longitudinal axis parallel by 2 ° to 4 °.

Other manufacturing techniques than sintering can be used, such as a stamping process or a forming process. All these production techniques have in common that can be produced by simple means in the longitudinal direction of the stator extending geometries.

A second embodiment of the invention will be discussed with reference to FIG. The same elements or comparable elements as in the first embodiment are provided with the same reference numerals and will not be described again.

In the second embodiment, the outer contour 6 of the stator main component 2 is again formed from prisms 8. In this case, the prismatic cross section 7 is formed alternately from subsections which are oriented either essentially in the radial orientation R or substantially in the circumferential direction U. This results in an outer contour 6 which has the shape of successive elevations 10 and recesses 11.

The outer contour 6 according to the second embodiment has the advantage that a

Forming connection between the stator base member 2 and the force receiving member is generated without a force component in the radial direction, so that a lifting of the force receiving member of the stator base member 2 is less likely. A third embodiment of the invention will be described with reference to FIGS. 4 and 5 explained. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again.

In the third embodiment, the outer contour 6 of the stator main component 2 is formed from prisms 8, which project alternately and successively in circumferential orientation U as projections 10 in the radial orientation R. As is particularly clear from Fig. 5, a radially outer extent 12 of the prismatic cross section 7 in circumferential orientation U is greater than a radially inner extent 13 of the prismatic cross section 7 in circumferential orientation U. The resulting between the elevations 10 recesses 1 1 have approximately the shape of a dovetail groove 14. This shape leads per recess 1 1 to two undercuts 15 by these undercuts 15 lifting of the power receiving component of the stator base 2 is prevented.

A fourth embodiment of the invention will be described with reference to FIG. 6. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again.

The stator main body 2 according to the fourth embodiment has a three-part outer contour 6. On the one hand, a multiplicity of prismatic cross sections 7 or prisms 8 extend in the direction of the longitudinal axis L from each end face 5. However, these prisms 8 do not extend that far that they come into contact with each other, but it is, on the other hand, formed between the prisms 8 a circumferential ridge 16. This tripartitioning is illustrated in FIG. 6 by dashed lines.

The prisms 8 per se are merely exemplified as formed in the second embodiment, and have the advantage that a positive connection between the Statorgrundbauteil 2 and the force receiving member is generated without a force component in the radial direction. The web 16 has the advantage that there is a form fit between the stator base component 2 and the force receiving component along the longitudinal axis L, so that a high force in the axial direction can be transmitted between the stator base component 2 and the force receiving component. The web 16 thus acts as an axial securing between the force receiving member and the

Statorgrundbauteil 2. The web 16 has the further advantage that he the

Statorgrundbauteil 2 stiffening acts, so that the Statorgrundbauteil 2 with less material use and therefore lighter, cheaper and / or can be constructed more efficient.

The fourth embodiment shows a further configuration of the outer contour 6, namely the prisms 8 on the side of the one end face 5 with respect to the prisms 8 offset on the side of the other end face 5 by an angle α in circumferential orientation U. It is particularly preferred in this case if the angle α corresponds to half the pitch of the prisms 8. This design leads to a particularly uniform distribution of the form-fit connections in circumferential orientation U and therefore to an overall particularly homogeneous force course between the force-receiving component and the stator base component 2.

It should be noted at this point that a particularly homogeneous force distribution between the force receiving member and the basic stator component 2 can additionally or alternatively also be achieved by reducing the size of the individual prisms 8 and at the same time increasing the number of prisms 8. This represents an optimization between size of the prisms, material properties such as modulus of elasticity or the like, production costs and / or component loads.

A fifth embodiment of the invention will be described below with reference to FIG. 7. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again. In the fifth embodiment, the outer contour 6 is formed as a circumferential web 16, which is raised in relation to an otherwise exemplary cylindrical surface 17. The web 16, as in the fourth embodiment has the advantages that this acts as an axial securing between the force receiving member and the stator base 2 and the Statorgrundbauteil 2 stiffening.

A sixth embodiment of the invention will be described below with reference to FIG. 8. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again.

The outer contour 6 according to the sixth embodiment differs from the outer contour 6 according to the fifth embodiment in that the web 16 is designed to be circumferentially interrupted. This offers over the outer contour 6 according to the fifth embodiment, the advantage of further weight savings.

Even if it does not result from the illustration of FIG. 8, that is

Statorgrundbauteil 2 according to the sixth embodiment provided with a plurality of web portions 18 which are dimensioned and arranged so that the center of mass of the stator main component 2 and the center of mass of the stator 1 lie on the longitudinal axis L, so that upon rotation of the stator 1 about the longitudinal axis L no unbalance effects occur.

A seventh embodiment of the invention will be described below with reference to FIGS. 9 and 10 described. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again. The outer contour 6 according to the seventh embodiment also has a web 16 which is raised relative to a cylindrical surface 17. On the web 16 axially oriented recesses 18 are formed. The axially oriented recesses 18 are present on the end faces 5 facing flanks 19 of the web 16. Furthermore, 16 radially oriented recesses 20 are formed on the web. The radially oriented recesses 20 are present on a substantially cylindrical outer surface 21 of the web 16.

Both the axially oriented recesses 18 as well as the radially oriented recesses 20 form a positive connection between the force receiving member and the stator base 2. The outer contour 6 according to the seventh embodiment therefore has the advantages that the web 16 offers, namely that between the force receiving member and axially securing the stator base 2 and that

Statorgrundbauteil 2 stiffening acts, as well as the benefits of a positive connection between see the force receiving member and the stator base 2 in Umfangsorientie- U, namely a particular suitability for transmitting torque between the force receiving member and the stator base 2. Another advantage is that the radially oriented recesses 20 and the axially oriented recesses 18 increase the surface of the outer surface 3, so that more material is available for a material connection between the force receiving member and the stator base 2.

The radially oriented recesses 20 open in the present case also in the flanks 19, therefore, these can also be described as substantially radially oriented or described as radially and axially oriented. The same also applies correspondingly to the axially oriented recesses 18, which open into the cylindrical outer surface 21 in the present case. This design increases the strength of protrusions of the force-receiving component engaging in the recesses 18, 20 and therefore leads to an even greater ability to transmit torque between the force-receiving member and the stator base component 2. The positive-locking surfaces of the outer contour 6 are preferably either substantially radially or substantially axially oriented, so that in the seventh embodiment, as in the second embodiment, there is the advantage that no force component is generated in the radial direction, so that lifting the force receiving member of the stator base 2 is less likely.

An eighth embodiment of the invention will be described below with reference to FIGS. 1 1 and 12 described. The same elements or comparable elements as in the preceding embodiments are provided with the same reference numerals and will not be described again.

As can be seen particularly clearly from the sectional view of FIG. 12, the web 16 of the outer contour 6 according to the eighth embodiment has a T-shaped cross section which extends in circumferential orientation U. This means that a radially inner flank section 22 of the web 16 is retracted relative to a radially outer flank section 23 of the web 16 along the longitudinal axis L, or that the radially outer flank section 23 in the direction of the respective end face 5 via the respective radially inner flank section 22 sticks out. Between the radially outer flank section 23 and the cylindrical surface 17, an undercut 15 is therefore formed in each case.

The design of the outer contour 6 according to the eighth embodiment has the advantages of the web 16, namely that it axially securing between the force receiving member and the stator base 2 and the Statorgrundbauteil 2 stiffening, and the advantage of the undercut 15, namely that a lifting of the force receiving member of the Statorgrundbauteil 2 is prevented.

A ninth embodiment of the invention will be described below with reference to FIG. Same elements or similar elements as in the previous The embodiments are provided with the same reference numerals and will not be described again.

The design of the outer contour 6 according to the ninth embodiment has the web 16, which is raised relative to the cylindrical surface 17. In the web axially oriented through holes 24 are formed, which extend from one edge 19 to the other edge 19 through the web.

This design has the advantages of the web 16, namely that this axially locking between the force receiving member and the stator base 2 and the

Statorgrundbauteil 2 stiffening acts, as well as the advantage that the through holes 24 a positive connection between the force receiving member and the

Stator basic component 2 with appropriate suitability for transmitting torque between the force receiving member and the stator base 2, the advantage of an undercut, namely that lifting of the force receiving member is prevented by the stator base 2, the advantage that during the formation of the force receiving member to the stator base 2 a The material forming the force receiving component can flow through the through holes 24 and thus a particularly uniform distribution of material is achieved, and the advantage that the through holes 24 reduce the mass of the stator main component 2.

Finally, it should again be pointed out that although the above embodiments all show, by way of example, the basic stator component 2 as basic stator component, the invention is not restricted thereto. In particular, by means of the outer contour 6, the force receiving component can be connected to a (not shown) stator cover. In particular, in the stator cover the web 16 can be replaced by a board.
