Description

Technical area

The present invention relates to a control rod and an actuating arrangement with such a control rod. Furthermore, the invention relates to a charging device with such an adjusting arrangement, as well as a method for producing the control rod according to the invention.

background

More and more vehicles of the newer generation are being equipped with charging devices in order to meet the requirements and legal requirements. When developing charging devices, it is important to optimize both the individual components and the system as a whole in terms of their reliability and efficiency.

Known charging devices usually have at least one turbine which is driven by exhaust gas from an internal combustion engine. The turbine is connected to a compressor via a common shaft, with the compressor compressing fresh air that is sucked in. This increases the amount of air or oxygen that the engine has available for combustion to react. This in turn leads to an increase in the performance of the internal combustion engine.

Modern charging devices are equipped with a power setting device, with the aid of which the power generation of the charging device can be set or changed. Known power adjustment devices are, for example, a variable turbine geometry or a wastegate flap. A variable turbine geometry is an adjustable guide device for changing an inflow to a turbine wheel of the turbine. By changing the inflow, in particular the flow velocity of the exhaust gas flow fed to the turbine wheel can be changed, which leads to a corresponding change in the performance of the turbocharger. In contrast to this, a wastegate flap essentially corresponds to an adjustable bypass through which exhaust gas can bypass the turbine wheel. By changing the cross-section of the bypass through which a flow can flow, the pressure difference between an inlet and an outlet of the turbine wheel can be changed, which has a corresponding effect on the performance of the turbine and thus on the performance of the supercharging device. An actuating arrangement is used to actuate such a power setting device. In addition to the power setting device, the setting arrangement comprises an actuator and a control rod, with the control rod being able to transmit setting movements of the actuator to the power setting device.

Due to the environmental conditions that prevail in the area of the charging device, there is an increased risk of wear and tear on the control rod. Due to the high exhaust gas temperatures in the turbine, high temperatures can also be transferred to the control rod. In addition, there are strong vibrations in the area of the control rack, which can lead to noise and wear and, together with the numerous load cycles to be completed, to fatigue and corrosion of the control rack. Above all, the vibrations and the associated disadvantages are increased by poor tribological properties in the respective coupling points to the power setting device and actuator device. In order to counteract the wear problems mentioned, control rods are often proposed in the prior art, which have a more complex and larger-sized system, which, however, often leads to a higher weight of the control rod. This results in a larger dimensioning of the actuator device and as a result of which the entire charging device becomes more inefficient. A more complex design of the control rod in turn leads to greater assembly costs, which on the one hand can lead to design restrictions and on the other hand to increased costs for the manufacture of the control rod.

The object of the present invention is to provide an inexpensive and wear-resistant control rod for an actuating arrangement of a charging device.

Summary of the invention

The present invention relates to a control rod according to claim 1. Furthermore, the invention relates to an adjusting arrangement with such a control rod according to claim 10, a charging device with such an adjusting arrangement according to claim 11, and a method for producing such a control rod according to claim 12.

The control rod comprises a rod section, a first end piece and a second end piece. The rod section has a first end region and a second end region, the first end piece being connected to the first end region of the rod section and the second end piece being connected to the second end region of the rod section. The first end piece is made of plastic and the second end piece is made of metal. This advantageous embodiment of the control rod enables reliable coupling between an actuator device and a power setting device of a charging device. As a result of that the first end piece is made of plastic, costs can be reduced through a simplified manufacturing process, a smaller number of components, lower material costs and functional integration. At the same time, by making the first end piece made of plastic, the total weight of the control rod is reduced, which in turn means that components, such as the actuator device, can be made smaller. This enables an advantageous reduction in the installation space of the charging device. At the same time, the control rod can be made wear-resistant. Since the first end piece, which can be coupled to the actuator device, is made of plastic, tribological properties can be specifically influenced for the coupling and required temperature properties of the materials used can be determined in a targeted manner. By choosing plastic instead of metal, additional damping is achieved. The second end piece, which can be coupled to the power setting device and is made of metal, is resistant to high exhaust gas temperatures which are transmitted to the power setting device by the turbine. In addition, the second end piece has a high level of wear resistance, since the limitation of play reduces vibrations which can be transmitted from the turbine to the power setting device and thus to the second end piece. Noise is also reduced by the vibration reduction.

In refinements of the control rod, the first end piece can comprise a first coupling section and a first receptacle. The first end piece can be connected to the rod section via the first coupling section of the first end piece. The first receptacle enables the control rod to be coupled to the actuator device. The first end piece can comprise a plastic ring which forms the first receptacle. The plastic ring of the first end piece can consist of more wear-resistant material than the first coupling section of the first end piece. In particular, the first end piece and the plastic ring can be integrally connected to one another by a composite casting process. The coupling section of the first end piece can consist of more temperature-resistant plastic than the plastic ring. Since the first end piece is connected to the actuator, the plastic ring which forms the receptacle experiences a lower temperature load than the coupling section, which extends in the direction of the turbine side and is connected to the rod section. Alternatively, the first end piece and the first receptacle can be formed in one piece from the same material.

In configurations of the control rod that can be combined with all of the preceding configurations, the second end piece can comprise a second coupling section and a second receptacle. The second end piece can be connected to the rod section via the second coupling section of the second end piece. The second receptacle enables the control rod to be coupled to the power setting device.

In configurations of the control rod that can be combined with all of the preceding configurations, the second end piece can comprise a metallic compensation ring which forms the second receptacle. In particular, the second end piece and the compensation ring can be connected to one another in a form-fitting manner. In this way, when coupling to the power setting device, an angle compensation can be achieved and play can be limited. It follows from this that manufacturing tolerances can be designed more precisely, which means that vibrations and thus wear are reduced due to reduced play. In refinements, the compensation ring can have a circumferential groove on its inner circumference, into which a snap ring, which is at least partially open in the circumferential direction, can be inserted. This arrangement makes the installation easier for the concealed installation of the power adjustment device.

In configurations of the control rod that can be combined with all of the preceding configurations, the second end piece can have two metallic halves that can be connected to one another by a joint connection, in particular a welded connection. The two metallic halves can each have a half shape of the end piece. The two metallic halves can be connected to one another, in particular by laser welding or resistance welding.

In configurations of the control rod that can be combined with all of the preceding configurations, the rod section can have a bent, angled or curved shape. As a result, an offset between the power setting device and the actuator device can be compensated for.

In configurations of the control rod that can be combined with all of the preceding configurations, the second coupling section can at least partially surround the second end region. In particular, the second coupling section can completely surround the second end region.

In configurations of the control rod that can be combined with all of the preceding configurations, the second coupling section can be designed in the form of a sleeve.

In configurations of the control rod that can be combined with all of the preceding configurations, the first coupling section can be connected to the first end region in a form-fitting and / or force-fitting manner.

In configurations of the control rod that can be combined with all of the preceding configurations, the first coupling section can be positively connected to the first end region by a composite casting process, with at least one undercut that can be formed between the first coupling section and the first end region preventing loosening can be.

The invention further relates to an actuating arrangement which comprises an actuator device, a power setting device and a control rod according to any one of the preceding embodiments. The control rod is coupled to the actuator device at the first receptacle and to the power setting device at the second receptacle.

The invention further relates to a supercharging device which comprises a turbine and an actuating arrangement of the preceding embodiment.

In refinements of the charging device, the power setting device can be designed as an adjustable guide apparatus for changing an inflow to a turbine wheel of the turbine, or as an adjustable bypass device for bypassing a turbine wheel of the turbine.

The invention further relates to a method for producing a control rod, the method comprising the following steps: providing a rod section and inserting a first end region of the rod section into a casting mold; Producing a first end piece and connecting the first end piece to the first end region of the rod section; Manufacturing and connecting a second end piece to a second end region of the rod section; wherein the first end piece is made of plastic and the second end piece is made of metal.

Detailed description

In the context of this application, the longitudinal axis means the axis which extends in the longitudinal direction of the control rod 10 extends which in 2 is indicated. The axial direction of the first and second end pieces means the directions which point in the direction of their coupling axis, orthogonal to the longitudinal axis of the control rod. This is done in 3rd and 4th indicated. A radial direction and a circumferential direction each relate to the longitudinal axis of the control rod or the axial direction of the first and second end pieces.

The positioning arrangement 30th comprises an actuator device 400 and a power adjuster 500 . A control rod 10 is designed to the actuator device 400 with the power setting device 500 to pair.

In 2 is the control rod 10 shown as a top view. The control rod 10 comprises a rod section 200 , a first end piece 100 and a second end piece 300 . The rod section 200 has a first end region 210 and a second end region 220 on, with the first end piece 100 with the first end area 210 of the rod section 200 is connected, and the second end piece 300 with the second end area 220 of the rod section 200 connected is.

The first end piece 100 is made of plastic and the second end piece 300 is made of metal. The rod section 200 is preferably also made of metal. The phrase “consists of” is to be interpreted in such a way that, for example, the first end piece 100 does not necessarily have to be made of 100% plastic. It can be the case, for example, that certain partial areas are formed from other materials, such as metal or ceramic, for example. However, the majority of the first end piece is made of plastic. So can the first end piece 100 consist of more than 70% plastic, preferably consist of more than 85% plastic and in particular consist of more than 99% plastic. The same applies to the second end piece 300 , also means that this does not necessarily have to be made of 100% metal.

• Die Zugfestigkeit des Kunststoffs kann nach ISO 527 im Bereich von 150 MPa bis 300 MPa, insbesondere von 200 MPa bis 270 MPa liegen. Die Wärmeformbeständigkeit (1,8 MPa) nach ISO 75 kann im Bereich von 250 °C bis 330 °C, insbesondere von 270 °C bis 310 °C liegen. Zudem weist der Kunststoff vorzugsweise einen linearen Wärmeausdehnungskoeffizienten nach ISO 11359 im Bereich von $\mathrm{1,3}\cdot {10}^{-5}\frac{1}{K}$
  
  bis $\mathrm{1,9}\cdot {10}^{-5}\frac{1}{K},$

The plastic from which the first end piece 100 exists, can preferably have the following properties:

• According to ISO 527, the tensile strength of the plastic can be in the range from 150 MPa to 300 MPa, in particular from 200 MPa to 270 MPa. The heat resistance (1.8 MPa) according to ISO 75 can be in the range from 250 ° C to 330 ° C, in particular from 270 ° C to 310 ° C. In addition, the plastic preferably has a coefficient of linear thermal expansion according to ISO 11359 in the range of $1.3\cdot {10}^{-5}\frac{1}{K}$
  
  to $1.9\cdot {10}^{-5}\frac{1}{K},$
  
  especially from $1.4\cdot {10}^{-5}\frac{1}{K}$
  
  to $1.8\cdot {10}^{-5}\frac{1}{K}$
  
  on.

The first end piece 100 is designed to work with the actuator device 400 to be coupled and the second end piece 300 is designed to work with the power setting device 500 to be paired. This advantageous embodiment of the control rod 10 enables safe coupling between actuator devices 400 and power adjustment device 500 . By having the first end piece 100 consists of plastic, costs can be reduced through a simplified manufacturing process, a smaller number of components, lower material costs and functional integration. At the same time, the execution of the first end piece 100 made of plastic, the total weight of the control rod 10 be reduced, which in turn leads to components such as the actuator device 400 , can be made smaller. This enables an advantageous reduction in the installation space of the charging device 40 .

At the same time, the control rod 10 provided in a wear-resistant manner. As the first end piece 100 , which with the actuator device 400 can be coupled, consists of plastic, tribological properties can be specifically influenced for the coupling and required temperature properties can be determined in a targeted manner. By choosing plastic instead of metal for the first end piece 100 additional damping is also achieved. The second end piece 300 , which with the power setting device 500 can be coupled and is made of metal, is resistant to high exhaust gas temperatures generated by the turbine 600 on the power setting device 500 be transmitted. In addition, the second end piece 300 A high level of wear resistance, as the limitation of axial and radial play reduces vibrations generated by the turbine 600 on the power setting device 500 and thus on the second end piece 300 be transmitted. Noise is also reduced by the vibration reduction.

As in 2 and 3rd can be seen includes the first end piece 100 a first coupling section 110 and a first shot 120 . This is the first coupling section 110 designed to end with the first 210 of the rod section 200 to be paired. Consequently, the first coupling section 110 the area of the first end piece 100 represents the one with the first end region 210 enters into a firm operative connection. The first shot 120 is designed with the actuator device 400 to be coupled and thus constitutes the area of the first end piece 100 represents the one with the actuator device 400 comes into operative connection. The second end piece 300 comprises a second coupling section 310 and a second shot 320 . This is the second coupling section 310 designed to match the second end region 220 of the rod section 200 to be paired. Consequently, the second coupling section 310 the area of the second end piece 300 represents the one with the second end region 210 enters into a firm operative connection. The second shot 320 is designed with the power setting device 500 to be coupled and thus constitutes the area of the second end piece 300 represents the one with the power setting device 500 comes into operative connection.

In the in 2 to 4th The embodiment shown comprises the first end piece 100 a plastic ring 130 which the first recording 120 for coupling with the actuator device 400 forms. The first end piece 100 and the plastic ring 130 are integrally connected to one another using a composite casting process. The coupling section 110 Made of more temperature-resistant plastic than the plastic ring 130 consist. This is advantageous because the coupling section 110 towards the turbine 600 extends and heat through the hot exhaust gas via the power adjustment device 500 , the second end piece 300 and the rod section 200 on the first end piece 100 can be transferred. The plastic ring 130 on the other hand, which is the first recording 120 forms, experiences a lower temperature load than at least parts of the first coupling section 110 . The control rod 10 is over the plastic ring 130 which the first recording 120 forms, with the actuator device 400 connectable, the plastic ring 130 Made of more wear-resistant material than the first coupling section 110 of the first end piece 100 consists. This allows tribological properties for the coupling to the actuator device 400 can be specifically determined, whereby the wear can be reduced. Since only the first shot 120 (and with it the plastic ring 130 ) consists of wear-resistant material and only the first coupling section 110 consists of more temperature-resistant plastic, the entire first end piece does not have to be 100 meet both properties, which can lead to lower material costs with appropriate selection. Alternatively, the first end piece 100 and the first shot 120 be formed in one piece from the same material. A plastic ring 130 does not have to be with the first end piece in this version 100 be integrally connected by a composite casting process. This leads to a lower number of components and simpler manufacture.

As in the 3rd and 4th can be seen, the second end piece 300 a metallic compensation ring 330 include, which is the second recording 320 forms. The compensation ring 330 has a cylindrical base body which has a spherically rounded outer circumference around its axial direction. This outer circumference is on an inner circumference of the second end piece 300 , which also has a spherical shape around its axial direction. The second end piece 300 and the compensation ring 330 are therefore positively connected to each other and the compensation ring 330 can move freely on the spherical path given in this way. Through the compensation ring 330 is the control rod 10 with the power setting device 500 connectable. Due to the freedom of movement of the compensation ring 330 on the spherical path becomes the power adjustment device during coupling 500 enables angular compensation and restricts axial and radial play. As a result, manufacturing tolerances can be designed more precisely, which reduces vibrations and thus wear.

In the in 2 to 4th The embodiment shown has the compensation ring 330 on its inner circumference 370 a groove 380 into which a snap ring 360 is used. The groove 380 is centered over the entire inner circumference 370 of the compensation ring 330 arranged. The snap ring 360 has an at least partially open scope. This is the snap ring 360 compressible or compressible, with its outer circumference changing temporarily. The snap ring can be inserted into the groove by compressing and thus temporarily reducing the outer circumference 380 can be used. After inserting the snap ring is 360 form-fitting in the groove 380 secured, with the snap ring 360 however, can move in the radial direction and in the circumferential direction through radial play. When assembling the control rod 10 with the power setting device 500 can be a bolt of the power adjustment device 500 be provided with a groove on its outer circumference. Will the bolt in the inner circumference 370 of the compensation ring 330 inserted, so is the snap ring 360 pushed apart by its at least partially open circumference, which temporarily expands its outer circumference until the snap ring 360 can snap into the circumferential groove on the bolt. This type of concealed assembly makes assembly easier. Through the snap ring 360 becomes the bolt in the compensation ring 330 axially secured without the need for additional fastening means for axial securing (such as two securing rings, each of which is attached to the bolt on the two end faces of the compensation ring). This leads to a reduction in the contact area for Vibrations, which also reduces wear.

In the in 2 to 4th The embodiment shown has the second end piece 300 a first metallic half 340 and a second metallic half 350 which are connected to one another by a joint connection, in particular by a welded connection. Alternatively, the two metal halves 340 , 350 be connected to one another by a rivet connection or a flanged connection. The two metallic halves 340 , 350 each have a particularly symmetrical half shape of the end contour of the second end piece 300 on. The two metallic halves are particularly preferred 340 , 350 connected to one another by laser welding or resistance welding. Thereby the two metallic halves 340 , 350 at at least two mutually spaced locations 390 connected. Alternatively or additionally, the two metallic halves 340 , 350 in the area of the second coupling section 310 connected with each other.

The rod section 200 the control rod 10 has a linear shape. Alternatively, the rod section 200 have a curved, angled, or curved shape. This makes it possible to have an offset between the power setting device 500 and the actuator device 400 balance. The second coupling section 310 has a hollow cylindrical shape that has the second end region 220 of the rod section 200 at least partially surrounds. In special designs, the second coupling section can be in the hollow cylindrical shape 310 at least one recess can be provided which, for example, can have a rectangular shape, a circular shape and / or an elongated hole shape. This recess can be used, for example, after the second coupling section has been pushed on 310 on the second end area 220 to weld these two components together. Alternatively or additionally, the second coupling section 310 and the second end region 220 on an end face of the second coupling section 310 are welded together. Alternatively or additionally, for example by means of laser welding, the material of the hollow cylindrical shape of the second coupling section 310 at any point in the area of the second end section 220 welded, the second coupling section 310 with the second end area 220 is connected. Alternatively, the second end area 220 with the second coupling section 310 connected by a screw connection, a clamping ring, a rivet connection or a flanged connection.

In some embodiments, the second coupling section 310 the second end area 220 completely surrounded. This is the second coupling section 310 sleeve-shaped.

As in the 2 and 3rd can be seen, the first coupling section 110 and the first end region 210 positively and / or non-positively connected to one another. The non-positive connection is based on an adhesion of the plastic material of the first end piece 100 on the first end area 210 generated. The first coupling section 110 can with the first end area 210 be positively connected by a composite casting process, with at least one undercut between the first coupling section 110 and the first end region 210 can be trained (see 2 ), loosening is prevented. The first end area 210 can for it, as in 2 indicated, have a section in the form of a parallelepiped, the cuboid having a length 1 along the longitudinal axis of the rod section 200 , a width b in a first plane in the radial direction to the longitudinal axis and a thickness d in a second plane in the radial direction to the longitudinal axis, orthogonal to the first plane. In one embodiment, the cuboid width b is greater than a diameter D of the rod section 200 . The cuboid thickness d is smaller than the diameter D of the rod section 200 . In order to generate a larger undercut area, the cuboid can have a geometric shape on at least one outer contour along the longitudinal axis which comprises at least one of a wave shape, a corrugated shape or a serrated shape.

In the composite casting process, the first end area 210 of the rod section 200 via a through hole 240 be fixed for positioning. After positioning, the first end area 210 encapsulated with plastic. In the composite casting process, the plastic material engages at least one of the through hole, the wave shape, the corrugated shape, the serrated shape or an attachment through the cuboid width b or cuboid thickness d, creating an undercut and thus a form-fitting connection. The first end area 210 is overmolded in such a way that the resulting first coupling section 110 across the length of the cuboid 1 out along the rod section 200 extends.

The invention also relates to an actuating arrangement 30th who have the actuator device 400 , the power setting device 500 and the control rod 10 includes. The control rod 10 is at the first recording 120 with the actuator device 400 coupled and attached to the second recording 320 with the power setting device 500 coupled. The actuator device 400 generates a rotary movement, which is due to the coupling to the first end piece 100 , for example via a lever arm, in a translational movement of the control rod 10 results. The translational movement of the control rod 10 is in turn by the corresponding coupling of the second end piece 300 with the power setting device 500 on the power setting device 500 transferred, in particular via a further lever arm again in the form of a rotary movement.

How out 1 As can be seen, the invention further relates to a charging device 40 who have favourited the turbine 600 and the actuator assembly 30th includes. The power adjustment device 500 can be used as an adjustable diffuser to change an inflow to a turbine wheel of the turbine 600 or as an adjustable bypass device for bypassing a turbine wheel of the turbine 600 be designed.

The invention also relates to a method for producing the control rod 10 . First the rod section 200 provided. The first end piece 100 is made and with the first end area 210 of the rod section 200 connected. The second end piece 300 is also made and with the second end region 220 of the rod section 200 connected. The first end piece 100 is made of plastic and the second end piece 200 is made of metal.

During manufacture, the first end area 210 of the rod section 200 be placed in a mold so that the first end area 210 of the rod section 200 can then be encapsulated with plastic to the first end piece 100 to form and at the same time the first end piece 100 form-fitting and / or force-fitting with the first end region 210 connect to.

The two metallic halves 340 , 350 are then connected to one another by a joint connection, in particular by a welded connection, so that the second end piece 300 is formed. Thereby the two metallic halves 340 , 350 welded.

Alternatively or additionally, the two metallic halves 340 , 350 with each other in the area of the second coupling section 310 welded. The two metallic halves 340 , 350 are in at least two spaced apart locations 390 welded together. As an alternative to the welded connection, it is possible to connect the two metal halves 340 , 350 a riveted connection or a flare connection can be used.

The metallic compensation ring 330 is between the first metallic half 340 and the second metallic half 350 , spaced from the second end area 220 , inserted. When connecting the two metallic halves 340 , 350 becomes the metallic compensation ring through the joint connection, in particular the welded connection 330 between the two metallic halves 340 , 350 positively secured, the second recording 320 of the second end piece 300 arises. This is done by the two metallic halves 340 , 350 the compensation ring 330 so positively secured that it can move freely on a spherical path.

The weld joint for connecting the second end region 220 with the second coupling section 310 can by welding through the material of the second coupling section 310 respectively. Alternatively or additionally, the welded connection is made on an end face of the second coupling section 310 intended. Alternatively or additionally, the welded connection is attached in a recess, the recess on a circumferential surface of the second coupling section 310 is appropriate. The recess has a rectangular shape, circular shape or elongated hole shape. Alternatively, the second end area 220 with the second coupling section 310 connected by a screw connection, a clamping ring, a rivet connection or a flanged connection.

The groove 380 is on the inner circumference 370 of the compensation ring 330 intended. During manufacture, it is then inserted into the groove 380 an at least partially open snap ring 360 used. The groove 380 is preferably in the middle of the inner circumference 370 of the compensation ring 330 intended. The snap ring 360 is positively locked in the groove 380 used. This is possible because of the partially open circumference of the snap ring 360 is radially compressible prior to insertion, so that its outer circumference is temporarily reduced during compression. When assembling the second recording 320 with the power setting device 500 becomes the bolt of the second power adjustment device 500 provided with a groove on its outer circumference. Will the bolt in the compensation ring 330 inserted, so the snap ring snaps 360 into the groove, whereby the bolt axially and radially in the compensation ring 330 is secured. This enables simple assembly of the actuating arrangement or the charging device. Through the snap ring 360 becomes the bolt in the compensation ring 330 axially secured without the need for additional fastening means for axial securing (such as two securing rings, each of which is attached to the bolt on the two end faces of the compensation ring). This leads to a reduction in the contact surface for vibrations, which also reduces wear.
