Definitions
- the invention relates to an automatic transmission in the form of a conical-pulley belt drive, as is known, for example, from DE 10 2004 015 215 and other publications, as well as a method for the production thereof and a vehicle equipped therewith.
- Identification transducers whose instantaneous transmission changes independently depending on current or expected operating conditions, such as partial load, thrust and environmental parameters, such as temperature, air pressure, humidity, gradually or continuously.
- identifier converters which are based on an electrical, pneumatic, hydrodynamic, hydrostatic principle or on a principle mixed up according to these principles.
- the automation relates to the most diverse functions, such as the starting, the translation choice, the type of translation change in various Be ⁇ drive situations, under type of translation change, for example, the switching of individual stages in succession, the skipping of switching stages and Geschwin ⁇ can be understood.
- the driver can intervene manually in the automatic sequence or limit it for individual functions.
- a starting unit in the form of a controllable clutch, for example a wet or dry friction clutch, a hydrodynamic clutch or a hydrodynamic converter.
- a hydrodynamic converter To a hydrodynamic converter is often connected a bypass clutch parallel to the pump and turbine part, which increases theides ⁇ degree by direct power transmission and attenuated by defined slip at critical speeds, the vibration.
- the starter unit drives a mechanical, continuously variable or stepped change gear that may include a forward / reverse unit, a main, range, split group and / or a variator.
- Gear transmission groups are, depending on the requirements of Laufru ⁇ he, space and transmission options designed in countershaft or planetary design with straight or helical teeth.
- the output element of the mechanical transmission drives directly or indirectly via intermediate shafts or an intermediate stage with a constant Koch ⁇ tion on a differential gear that can be designed as a separate transmission or is an integral part of the automatic transmission.
- the transmission is suitable for longitudinal and transverse installation in the vehicle.
- a hydraulic pump which operates according to the displacement principle supplies pressurized oil for the starting unit, in particular the hydrodynamic unit, for the hydrostatic adjusting elements of the mechanical transmission and for the lubrication and cooling of the system.
- gear pumps, screw pumps, vane pumps and piston pumps the latter being mostly of a radial design, are suitable.
- gear pumps and radial piston pumps have prevailed for this purpose, the gear pumps offering advantages because of their low construction costs and the radial piston pump because of the higher pressure level and better controllability.
- the hydraulic pump can be arranged at any point of the transmission on a continuously driven by the drive unit main or secondary shaft.
- Stepless automatic transmissions consisting of a starter unit, a planetary gear transmission as a forward / reverse drive unit, a hydraulic pump, a Va ⁇ riator, an intermediate shaft and a differential.
- the variator in turn consists of two conical disk pairs and a belt.
- Each conical disk pair consists of a second conical disk which can be displaced in the axial direction.
- Between these cones disc pairs runs the belt, for example, a push belt, a pull chain or a belt.
- the running radius of the Umschlingungsorgans and thus the transmission of the stepless Automat ⁇ transmission changes.
- Infinitely variable automatic transmissions require a high level of pressure in order to be able to adjust the variator's conical disks at the desired speed at all operating points and, moreover, to transmit the torque largely wear-free with a sufficient basic contact pressure.
- Toroidal friction vibrations are known, for example, as plucking at frequencies of 10 Hz from couplings. If the coefficient of friction under slip change is such that the coefficient of friction drops, plucking is excited. In the case of automatic transmissions, the steel-paper coefficient of friction is primarily relevant here.
- An object of the invention is to improve the acoustics of such a transmission and thus to improve the comfort in particular the noise comfort of a vehicle equipped with such a transmission.
- Another sub-task on which the invention is based is, after the analysis, higher-frequency, stronger CVT oscillations and the related clarification of the corresponding Wirk ⁇ mechanisms to represent appropriate countermeasures to minimize these vibrations, which are predominantly in the acoustic range in the order of 400-600 Hz, or possibly to prevent.
- a further sub-task of the invention is to increase the operating stability of components and thus to extend the service life of such an automatic transmission.
- a further sub-task of the invention is based on increasing the torque transmission capability of such a transmission or transferring larger forces through the components of the transmission. In addition - so a further Detail ⁇ task - such a transmission should be able to be manufactured economically.
- the object is achieved by a conical-pulley belt drive having drive-side and driven-side cone pulley pairs, each having a fixed disk and a washer, which are each arranged on a drive-side and an output-side shaft and connectable via a belt connection for torque transmission, wherein at least one of the factors listed in terms of Acoustics of the transmission is optimized:
- the invention relates to a vehicle with a transmission according to the invention.
- FIG. 1 is a partial view of a conical-pulley transmission
- Figure 2 is a substantially corresponding to Figure 1 representation of another
- FIGS. 5 and 6 show schematic design possibilities of windscreens.
- the conical-pulley belt transmission 1 has on its input side a shaft 3, which in the illustrated embodiment is formed integrally with a fixed conical disk or fixed disk 4. This axially fixed conical disk 4 is located in the axial longitudinal direction of the shaft 3 of an axially displaceable conical disk or disk 5 adjacent.
- the link chain 2 on the drive-side cone pulley pair 4, 5 is shown in a radially outer position, which results from the fact that the axially displaceable conical disk 5 is displaced in the direction to the right and this displacement movement of the axially displaceable conical disk 5 leads to a movement of the La ⁇ chain 2 in the direction radially outward, resulting in a ratio change of the transmission in the fast.
- the axially displaceable conical disk 5 can also be displaced to the left in a manner known per se in the drawing plane, wherein in this position the link chain 2 in FIG a radially inner position (which is provided with the reference numeral 2a), in which results in a translation of the conical-pulley belt transmission 1 slow.
- the torque provided by a drive motor, not shown, is introduced into the drive-side part of the conical-disk belt transmission shown in FIG. 1 via a toothed wheel 6 mounted on the shaft 3, which receives on the shaft 3 via a roller bearing in the form of an axial and radial forces Bearing 7 is mounted, which is fixed on the shaft 3 via a disc 8 and a shaft nut 9.
- a torque sensor 10 to which a spreading disk configuration 13 provided with an axially fixed expanding disk 11 and an axially displaceable expanding disk 12 is assigned.
- a spreading disk configuration 13 provided with an axially fixed expanding disk 11 and an axially displaceable expanding disk 12 is assigned.
- rolling elements are arranged for example in the form of the balls 14 shown.
- the torque sensor 10 has two pressure chambers 15, 16, of which the first pressure chamber 15 is provided for acting on pressure medium as a function of the introduced torque and the second pressure chamber 16 is supplied with pressure medium, specifically as a function of the transmission ratio.
- a piston / cylinder unit 17 which accommodates two pressure chambers 18, 19.
- the first pressure chamber 18 is used for the translation-dependent change in the Beauf ⁇ suppression of the plate link chain 2 and the second pressure chamber 19 is used in conjunction with the torque-dependent controlled pressure chamber 15 of the torque sensor 10 to increase or decrease the contact force with which the link chain 2 between the conical disks 4, fifth is charged.
- the shaft 3 has to supply pressure to the pressure chambers three channels 20, is fed via the pressure medium from a pump not shown in the pressure chambers. About one outlet-side channel 21, the pressure medium can flow out of the shaft 3 and fed back to the circuit.
- the application of pressure to the pressure chambers 15, 16, 18, 19 leads to a torque- and translation-dependent displacement of the axially displaceable conical disk 5 on the shaft 3.
- the shaft 3 has 5 centering surfaces 22 for receiving the displaceable conical disk, which serve as a sliding seat for the displaceable one Conical disk 5 serve.
- the cone pulley belt transmission 1 has a respective noise damping device 23 in the region of the bearing points of the conical disk 5 on the shaft 3.
- the noise damping device can have a ring body and a damping insert or only one consist of damping insert.
- FIG. 1 also refer to the substantially comparable features of the further figures. The figures are therefore to be regarded as a unity. For the sake of clarity, only those reference symbols which go beyond those of FIG. 1 are used in the other figures.
- FIG. 2 the middle of the three channels 20 is now configured in a modified form compared to FIG. It can be seen that this hole 24 forming the central channel 20, which is produced as a blind hole bore from the side shown to the right on FIGS. 1 and 2, is made significantly shorter than in FIG. 1.
- Such blind holes are expensive to manufacture and require one very high degree of accuracy in production.
- Theticians ⁇ effort and the requirements in terms of process reliability increase overproportional with the length.
- the shortening of such a hole thus has a favorable z. B. on the manufacturing costs.
- the transverse bore 25 branches off, of which several can be arranged distributed around the circumference. In the case shown, this transverse bore 25 is shown as a radial bore; However, it can also be made at a different angle than Schräg ⁇ bore.
- the bore 25 penetrates the lateral surface of the shaft 3 at a location which is independent of the operating state, ie z. B. of the set translation, in an area that is always covered by the travel plate 5.
- the shaft 3 By laying the transverse bore 25 in the overlap region of the spacer plate 5, the shaft 3 can be made axially shorter, which space can be saved. In addition, the shortening of the shaft 3 can also result in a reduction in load.
- the mouth of the channel or the transverse bore 25 can be arranged, for example, in the region of the recess 26 which is adjacent to the centering surface 22 of the shaft. This can be particularly advantageous if the toothing 27, which axially displaceably connects the travel disc 5 to the shaft 3 in a manner that is displaceable axially, is subjected to high stress, for example by the torque transmission.
- the loading of the toothing 27 will not be the most critical design criterion, so that the mouth of the bore 25 can be placed in the region of this toothing, as shown in FIG.
- the area moment of inertia is greater at this point, while the critical fiber which is disturbed by the transverse bore 25, remains at approximately constant radius. This results in a significant reduction in the stresses in the critical Be ⁇ rich around the mouth of the transverse bore 25 between the teeth of the teeth 27.
- control bores 30 are exposed, so that the thus connected in Ver ⁇ binding, with a stopper 31 axially sealed channel 20 and communicating with him via a channel, not shown pressure chamber 16 are depressurized or le ⁇ diglich ambient pressure exhibit. If the travel disc 5 is then moved toward the fixed disc 4, it passes over the control bores 30, the chamber 29 coming to lie above the mouths of the control bores 30 at a certain distance. In the chamber 29, however, there is a dependent on the moment high pressure, which is then brought via the Steuerbohrun ⁇ gene 30 and the channel 20 in the pressure chamber 16, so that there are also higher Pressure is applied. In this way, two switching states are realized, which control the contact force translation-dependent.
- FIG. 2 provides a disk spring 32 which, in the pressureless state of the transmission 1, brings the travel disk 5 into a predetermined axial position, whereby a transmission gear ratio 1 can be adjusted which causes excessive loading, for example during the operation Towing the vehicle, prevented.
- FIG. 3 shows two diagrams which show the coefficient of friction over the sliding speed as a function of the contact pressure.
- the sliding speed is shown in each case on the abscissa and the coefficient of friction on the ordinate.
- the coefficient of friction is a function of the sliding speed, which tends to decrease with increasing sliding speed.
- the respective distance of the curves in the ordinate direction represents the spread of the coefficient of friction as a function of the contact pressure or contact pressure.
- the lower line stands for low contact pressure and the upper one for a high contact pressure.
- FIG. 4 The diagrams in FIG. 4 are essentially constructed like those in FIG. 3, but do not show the dependence on the oil used, but on the surface characteristics. The interpretation given in relation to FIG. 3 also applies to FIG. 4, d. H. the lower diagram documents a significant improvement in the conditions.
- the upper diagram of FIG. 4 shows the conditions on a polished surface
- the lower diagram of the FIGURE represents the coefficient of friction as a function of sliding speed and contact pressure in the case of surface characteristic values according to the invention.
- These surface area characteristics are z. B. produced by a finishing process, the Reibparame ⁇ ter have the right course and keep this over a longer period. For example, noise phenomena occur on smoother surfaces immediately, while at rougher surfaces later, at best, never occur. Such an improvement with regard to the noise behavior can also be achieved by reducing the contact pressure or contact pressure.
- FIGS. 5 and 6 schematically show profiles of a travel disc, wherein in each case only the upper half of the rotationally symmetrical profile is shown.
- FIG. 5 shows in each case a stiffening of the disk itself.
- a part of the driven-side, axially movable disk or travel disk 33 is shown schematically in FIGS. 5 and 6, comparable Designs can also be transmitted to the drive-side path plate 5.
- the spacer disk 33 shown in FIG. 5a has, in its region facing away from the belt 2, a plurality of stiffening ribs distributed over the circumference, which reduce or at best prevent axial displacement of the radially outwardly projecting part of the disk 33, thereby counteracting opening up of the disk pair becomes.
- the spacer disk 33 according to FIG. 5b has a configuration in which the region of the spacer disk 33 projecting radially outwards is reinforced such that its wall thickness increases radially outward. This is achieved by means of a corresponding design of the contour of the disk facing away from the looping means 2. The course of this contour, which is shown continuously here, can also be modified in such a way that the wall thickness increases in several stages.
- a stiffening collar 35 can also be attached radially on the outside, as shown in FIG. 5c.
- FIG. 5 d shows, in addition to the radially outwardly disposed stiffening collar 35, a further stiffening collar 36, which is arranged radially further inwards and thus can optionally also serve as a separation between two pressure chambers. - IO -
- FIGS. 5c and 5d the stiffening collars 35 and 36 are shown as separate parts or circular rings which are to be connected to the travel plate 33.
- FIG. 5e now shows a possibility of integrally embodying the reinforcing collar 35 and / or the reinforcing collar 36 with the spacer disk 33, whereby a design suitable for production can be taken into account in an advantageous manner.
- FIGS. 5f and 5g show a stiffening of the connection of the disk to the shaft.
- the hub 37 of the spacer disk 33 is connected to the radially outwardly projecting part of the spacer disk 33 via a stiffening ring 38, so that a deformation of this region is at least reduced.
- stiffening ribs 34 are again provided which are connected, on the one hand, to the stiffening ring 38 and, on the other hand, to the hub 37 of the travel disc 33.
- FIGS. 6a to 6e principal damping possibilities for the output-side, axially movable disk or travel disk 33 are shown, which, however, are also applicable to the drive-side, axially movable disk or travel disk 5.
- FIG. 6a initially shows a subdivision of the hub 37 into individual lamellae, wherein this lamella packet is compressed by the contact pressure which is applied via the hydraulic medium and thus causes a damping.
- the stiffening collar 35 is additionally designed as a plate pack, which in turn is pressed together by the contact pressure.
- the stiffening collar 36 located radially further inward can also be designed as a disk set, wherein this stiffening collar 36 can again be used as a separation between different pressure chambers.
- the hub 37 can also be subdivided into individual lamellae.
- FIGS. 6f and 6g another approach is shown which consists in changing the direction of tilting of the path plate.
- Disc over its radially inner region or via its hub 37 shows the radially outer Be ⁇ rich this distance disc the largest deflection in the tilting direction.
- tilting or distortion of the spacer disk 33 between the guides is avoided.
- Torque sensor axially fixed expansion disc axially displaceable expansion disc
