Description
Technical Field
The invention relates to a belt pulley decoupler for suppressing rotational irregularities, comprising: a belt pulley having a belt receiving area for force-transferring contact with an endless traction element, such as a (toothed) belt; and a cover mounted on the pulley, wherein the pulley is prepared for introducing or discharging torque; a driving flange, preferably separate from the belt pulley, for the purpose of guiding out or introducing a torque, wherein the driving flange is arranged, for example, radially inside the belt receiving region; and an elastic element, such as a spring, arranged between the belt pulley and the driving flange, wherein the elastic element connects the driving flange to the belt pulley in a torque-transmitting and vibration-damping manner.
Background
Such a device is known from international publication WO 2012/075984 a 1. This publication discloses a pulley damper for damping torsional vibrations of a drive shaft, wherein the pulley damper has a pulley for driving a traction means and furthermore has an input flange which can be fixedly connected to the drive shaft, wherein the input flange has at least one fastening means for connecting the input flange to the drive shaft. In addition, this publication discloses a torsional vibration damper, in particular a decoupler for torsional vibrations, for transmitting a torque introduced via an input flange to a belt pulley. A support is formed between the belt pulley and the input flange for supporting the belt pulley on the input flange.
Also in this technical field is the international publication WO 2008/058499 a 2. This publication discloses a drive wheel having: at least one drive disc (in particular a belt disc); and a torsional vibration damper arrangement comprising an input part and an output part, the output part being rotatable relative to the input part against a damping effect of at least one torsional vibration damper element, in particular against a damping effect of a plurality of torsional vibration damper elements. The apparatus disclosed in the publication is characterized in that: the torsional vibration damper arrangement is optimized with regard to its service life and/or the production costs of the drive wheel.
Furthermore, international publication WO 2007/062620 a1 describes a torsional vibration damper. The device disclosed herein therefore relates to a torsional vibration damper, in particular a flywheel having at least two partial parts of a flywheel mass which can be rotated against the resistance of at least two deformable energy storage elements (in particular helical compression springs), which are coupled to one another by at least one coupling device, wherein the coupling device is relaxed, in particular, when a first energy storage element is deformed, to bring about a targeted driving of a second energy storage element, and the torsional vibration damper has at least one first driving device and one second driving device. In this way, undesired vibrations are prevented during operation of a motor vehicle equipped with the torsional vibration damper.
Belt pulley decouplers and dual mass flywheels with bow springs are known from the prior art. In the belt pulley decouplers known from the prior art, the cover is surface-hardened and pressed into the belt pulley which is not hardened. The cover therefore acts as an abutment surface for the bow spring and must therefore be hardened to limit wear. Furthermore, the cover must be constructed with a complete abutment surface for the bow spring. Because the cover and the pulley are compressed, their contact surfaces need to be manufactured with certain tolerance requirements. Therefore, raw materials, material handling and processing of the lid are significant cost drivers.
Primary plates connected to the cover by a weld seam are known in dual mass flywheels of the prior art
Bow springs and embedded shells. The weld seam is a secure connection, as a result of the high forces. However, the connection is costly if manufacturing and assembly tools are considered.
Different embodiments of torsional vibration dampers are therefore known from the prior art, which enable a vibration-damping connection of two components.
The prior art disclosed in these documents has the disadvantage that the manufacturing costs of the belt pulley decoupler are very high on the one hand and moreover cause high wear, i.e. high maintenance costs for the manufacture of the appliance. Furthermore, the belt pulley is a component with a complex geometry, which, according to the prior art, partially or completely carries out a hardening process. There is currently a bias to stiffen the cover but keep the pulley "soft".
Disclosure of Invention
The object of the invention is to eliminate the disadvantages of the prior art and in particular to enable economical manufacture and production of a belt pulley decoupler while at the same time minimizing wear.
This is solved according to the invention in such a device in that: between the belt pulley and the elastic element, for example radially inside the belt receiving region, preferably fixedly with the cover and/or fixedly with the belt pulley, a slide-guide housing separate from the cover and the belt pulley is arranged, which slide-guide housing is configured on one side, for example on its radially inner side, with a contact surface supporting the elastic element. The slide-guiding shell is therefore suitable for being connected to the elastic element and receiving possible friction forces and withstanding the expected wear. The slide guide housing is a structurally simple or non-luxurious solution, whereby it brings both economic advantages and a simplified assembly.
Advantageous embodiments are set forth in the dependent claims and are set forth in detail below.
It is therefore advantageous to harden the slide-guiding shell at least in the region of the contact surface, in particular to form it partially from a material which has already undergone a separate technical hardening process. In this way, it is ensured that the slip-conducting housing has a strength which also compensates for the high friction forces on the spring element side. This results in a constant contact surface between the slip-guiding shell and the spring element, since the formation of furrows (Furche) is avoided due to the high material quality which is produced by the technical hardening process.
A further advantageous embodiment is characterized in that the slide guide shell is designed as a complete and/or slotted ring in the circumferential direction or as a partial shell, for example a half shell or a circular shell segment. This results in: at least one contact line is always present between the sliding guide housing and the spring element, which contact line enables a continuous force closure from the spring element to the sliding guide housing. Furthermore, it is useful: the radially outer region of the spring element does not rest against the belt pulley but against the slide guide housing. This results in: the material and surface properties of the slide guide housing are configured in such a way that the slide guide housing is optimally adjusted to the conditions determined by the sides of the spring element.
This also has positive aspects if the slide guide housing is connected in a rotationally fixed manner to the belt pulley in a non-positive, form-fitting and/or material-fitting manner (for example by means of a press fit). The press fit thus enables the slide guide housing to rest in the belt pulley without play, thereby resulting in a high degree of certainty. Furthermore, the press fit is a structurally simple solution which is reliable and cost-effective.
This is a positive aspect as long as the projections extending from the cover and/or from the belt pulley, which define the bow spring abutment faces, serve for positioning and/or holding the slide-guide housing in one piece, or for positioning and/or holding the slide-guide housing constructed from a plurality of segments. Since the securing of the slide-guiding housing is ensured by the driving/abutment surfaces provided for this purpose. The contact surface can be adapted to the requirements set on it, since its function is to create a reliable press fit between the slide guide housing and the spring element. This embodiment therefore ensures that the fitting itself is subjected to the highest loads. The assembly is also associated with only a small outlay because of the advantageous configuration of the abutment surfaces.
It is also advantageous if a rotationally fixed connection is produced between the cover and the belt pulley merely or additionally by a press fit. Such a press fit improves the stability of the unit without introducing complicated and expensive structural complications. The press fit is therefore ideally suited for establishing/supporting the torsion-resistant connection.
A further advantageous embodiment is characterized in that the cover covers the volume defined by the belt pulley, or the interior of the belt pulley receiving the elastic element, and/or that the cover is connected to the belt pulley solely or additionally by means of a press fit. This is therefore caused by the assembly with the cover: the belt pulley decoupler is partly delimited unambiguously by the other components. The other member is also connected with the pulley by means of a press fit, thereby causing the cover to be securely attached to the pulley.
It is also advantageous if the belt pulley has a stop on its side facing the cover, which stop is directed in the axial direction, and a stop which is directed radially inwards, wherein these two stops produce a press fit with the cover. This results in a geometric certainty for the cover, since the cover is determined both in the axial direction by the axial stop and in the radial direction by the radial stop. This brings advantages in the assembly, since the place where the cover abuts is clearly defined. Furthermore, an assembly having the two stops enables an efficient press fit, since the press fit has an axial surface in addition to the radial abutment surface required for this purpose. The complexity of the device is thus reduced, while at the same time the operational safety of the device is increased.
A further advantageous embodiment is characterized in that the spring element is configured as an arcuate helical spring. The bow coil spring is a standard component and therefore brings economic advantages. Furthermore, the bow coil spring has been operated in many applications, thereby causing a positive scale effect.
A further advantageous embodiment provides that an auxiliary drive of the internal combustion engine, which has the belt pulley decoupler disclosed above, is in active relationship with the belt motor generator. This enables interaction between the belt motor generator and the pulley decoupler. Thus, for example, the auxiliary drive/auxiliary mechanism can be started by the belt engine generator side, thereby increasing the application versatility of the device according to the invention.
It is also advantageous if the slide-guiding housing has, at least in the region of the contact surface, a profile in a cross section along the rotational axis of the belt pulley decoupler, which profile in said cross section is at least partially, preferably over a large area or completely complementary to the radially outer contour of the spring element. This makes it possible to achieve an efficient fit, since in operation, in the event of possible relative movements between the sliding guide housing and the spring element, loosening of the contact line is not likewise caused. Furthermore, installation space is thereby utilized optimally.
It is also advantageous if the belt pulley has a penetration ramp which enables the centering of the cover. This gives a significant time advantage in assembly, since the cover can be connected to the belt pulley without great difficulty. Thereby improving the overall system economy.
A further advantageous embodiment is characterized in that, in addition or alternatively, the connection between the belt pulley and the cover is established in a material-locking manner, in particular by means of a welded connection. Thus increasing flexibility. Furthermore, a material-locking connection, in particular a welded connection, has the following advantages: the connection itself is subjected to the highest loads without play.
Another advantage is that a lubricating material is present in the inner volume defined by the cover and the pulley disc, wherein the additional sealing body keeps the lubricating material in the inner volume. The cooperation of the cover and the belt pulley ensures therefore that: the internal volume is fluidly sealed from the external volume/environment.
It is also advantageous to provide for this purpose a driving flange connected to the rotating element, in particular to the crankshaft of the internal combustion engine. This results in a further range of applications of the device according to the invention. On the one hand, it is thus possible to implement an auxiliary unit for driving the internal combustion engine, while the following variants remain: the internal combustion engine in the transition state is brought/started into the steady state by means of the belt drive.
It is also advantageous if the press fit is caused by the pretensioning of the slotted guide shell. The sliding guide housing is thus responsible for a fixed connection between it and the elastic element. The friction-locking variant produced by press fitting can thus be easily adjusted by pretensioning the slide guide housing. Thereby increasing the flexibility of the overall assembly.
In other words, it can be expressed as: the device according to the invention assumes its use in drive trains, transmissions, motors, belt drives and chain drives and other fields of application. In this case, the device is always combined with a decoupling function (Entkoppelung) of the input element and the output element.
Advantageously, the length of the press fit measured in the axial direction, which length is between the cover and the belt pulley, is smaller than or equal to the thickness of the cover, can also be referred to as the press-in length.
There are therefore the following solutions: in this solution, the disadvantages mentioned at the outset are reduced and implemented in a belt pulley decoupler. This means that manufacturing costs are optimized by reducing raw materials, material handling and processing.
For this purpose, the two (side) sheet materials covering the bow spring are held soft, i.e. not hardened, the press-in length between the cover and the pulley is changed, and the position of their abutment faces is moved in the axial direction towards the cover, and, in addition, one or more slide-guide shells are used.
The belt pulley and the cover constitute a housing and are not hardened. The cover is pressed against the belt pulley. The penetration ramp and the stop contour are on the belt pulley, the cover being pressed onto said stop contour. It is also conceivable to press the cover in place. The retention force required for a press-fit bond (Pressverband) can be adjusted as a function of the overlap between the outer diameter of the cover and the inner diameter of the contact surface of the pulley. The force range transmitted (Kraffland) is additionally adjusted by tolerances. Care must of course be taken to the deformation of the pulley and the cover due to said press-fit engagement. In order to increase the forces to be transmitted between the cover and the belt pulley, it is possible to selectively wedge partially, over a large area and over the entire circumference of the cover. For this purpose, the penetration ramp can be used, for example.
In very high loads, for example in the case of a bursting rotational speed, a weld seam between the belt pulley and the cover is also conceivable. As already indicated, the belt pulley must match the load due to the bow spring.
If the lubricant material would escape as a result of the load, it can be prevented in a targeted manner by a wedging device or by a sealing body (e.g. a sealing foil/paper or an O-ring). The sliding guide housing as a friction surface for the bow spring can be designed as a complete ring or also as a half-shell or as a partial housing. In the case of a partial housing, it is expedient for the housing to be positioned and held by, for example, a bow spring abutment face. The shell must be constructed such that: so that the movement of the bow spring is not hindered and wear is kept small.
In a specific application, a decoupler is provided which is connected to the crankshaft and can transmit a force from the internal combustion engine via its spring element and its pulley to the belt drive and can transmit it via the belt drive to the auxiliary mechanism. In combination with a belt starter generator, a force can be transmitted in return from the belt drive to the internal combustion engine. The spring element decouples vibration irregularities from the internal combustion engine to the belt drive. It is also conceivable to implement this solution in a dual mass flywheel in a manner corresponding to the requirements, in particular when a rotationally fixed connection is to be produced by means of a press-fit connection between the cover and the belt pulley only.
It is emphasized that: the concept of the presented slip-guide shell can be used, on the one hand, as explained in the context of a belt pulley decoupler, and, on the other hand, the concept with all of its presented features can also be used in a dual mass flywheel.
Summarizing, it can be stated that the manufacturing costs are reduced in this way: in a belt pulley decoupler, the slip guide housing is used as a friction pair for the bow spring. This eliminates the need to harden the side metal sheet, thereby eliminating the hardening process. The material sandwich below/radially inside the belt pulley is additionally eliminated and replaced by a short press-fit bond between the belt pulley and the cover. Furthermore, it is possible to provide a wedging device in order to increase the maximum transmissible force.
Drawings
The invention is explained in detail below with the aid of the figures.
It shows that:
fig. 1 shows a longitudinal section through a radial end of a belt pulley decoupler according to the invention along the axis of rotation, wherein only the elements relevant to the invention are shown.
The drawings are merely schematic in nature and are used only for the understanding of the present invention. Like elements are provided with like reference numerals.
Detailed Description
Fig. 1 shows a belt pulley decoupler 1 constructed from a plurality of elements. The belt receiving area 2 is characterized in that it is the radially outer area of the pulley 3. The belt pulley 3 is adapted to receive a ring. A driving flange 4 is arranged radially inside the belt receiving region 2. Between the driving flange 4 and the belt pulley 3, an elastic element 5, i.e. a spring, is arranged. The spring element 5 connects the driving flange 4 to the belt pulley 3 in a torque-transmitting and vibration-damping manner.
The other core component of the assembly is the slip-on shell 6. The slide guide housing 6 has a defined contact surface 7 which is in contact with the spring element 5. The assembly of the cover 8 is of central significance as well. The cover 8 relates to a means of spatially isolating the pulley decoupler 1 from the environment. By means of the cover, a lubricating material, for example grease, can be provided in the belt pulley decoupler, without said lubricating material coming into contact with surrounding components in the drive train.
In one embodiment, the slide-guide housing 6 arranged in the belt pulley 3 so as to be rotationally fixed is fixed by means of a press fit. In another embodiment, the press fit can be bypassed. For this purpose, the assembly has a cover projection 9 and a pulley disc projection 10. These two abutment surfaces are suitable for fixing the slide guide housing 6 in such a way that relative movement is no longer possible between the slide guide housing and the pulley 3.
Another feature of the invention is the abutment surface between the pulley 3 and the cover 8. Said abutment surface is characterized by an axial shoulder 11 and a radial shoulder 12. Said shoulders, i.e. the axial 11 and radial 12 shoulders, enable the cover 8 to be brought into a press fit with the pulley 3. The press fit ensures that the cover 8 is connected to the pulley 3 in a rotationally fixed manner. In addition, in another embodiment, the belt pulley 3 can be fixed to the cover 8 by means of an additional material connection (for example a welded connection) in the event of forces occurring during operation which are too great to be absorbed by the frictional force closure.
A so-called lead-in ramp 13 is provided on the belt pulley 3 for centering the cover 8 on the belt pulley 3. The advantages of the lead-in chamfer 13 are particularly apparent during assembly. Since this lead-in chamfer enables the centering of the cover 8 on the belt pulley 3.
In fig. 1, the elastic element 5 is represented as a bow-shaped helical spring 14. The bow coil spring has a circular profile in longitudinal section along the axis of rotation of the pulley decoupler 1. It is obvious here that the axis of symmetry, which extends precisely in the radial direction, extends in the axial middle of the driving flange 4. As a result, a very efficient force or torque transmission between the driving flange 4 and the spring element 5 (in this case the bow coil spring 14) can be achieved.
Furthermore, the invention is characterized by a friction surface 15. The friction surface is the position at which the elastic element 5 and the sliding guide housing 6 are connected. The spring element 5 has already been reworked in a separate technical hardening process, and the friction surface 15 enables a relative movement of the parts in contact there without causing permanent damage to the material. Furthermore, the formation of grooves in the slide guide housing 6 is avoided. The linear friction surfaces extending in the circumferential direction between the sliding guide housing 6 and the spring element 5 can be realized: the participating components are optimally adapted to the operating conditions with regard to their material and surface properties. The belt or test roller is partially designated by reference numeral 16.
