In order at the end of the editing process when unloading cantilever plates to provide less or virtually eliminate springing or return to the initial position of the cantilever plates or segments cantilever plates, it is advantageous if at the expense of heat in the zone of deformation of the cantilever plates the strength of the material, at least in some places, reduced the strength of the material in the heated zone of deformation should be, therefore, decreased, at least in some places up to 0 N/mm2.

The preferred way diaphragm spring before you edit cantilever plates with respect to each other can be at least partially subjected to blasting. The heated zone of the cantilever plates can be positioned with the possibility of at least partial thermocalc diaphragm spring. This thermoacetica due to the heat being heated areas due to thermal conductivity of the material emit in the elastically deformable or springy areas of the diaphragm spring. These plots can be formed, for example, the annular body Belleville springs.

A preferred manner, the method may find application for disc springs with a circle, serving as a battery energy body, which at its radially inner and/or radially outer section of the periphery contains molded in one piece cantilever plate, for example in the form of reeds. These cantilever plate can be held in the radial direction or in the direction of the periphery. The preferred manner similar to the disc spring, or at least its annular body may at anapra who s directed radially inward tabs separated from each other radially through the slots in the form of slits.

The preferred way for mutual edit cantilever plates all console plate can be purposefully heated at a given site, i.e. in the restricted area, and deformed together. In particular, the Belleville springs for use in combination with a friction clutch can be especially beneficial if by editing console plates or reeds, at least their free end sections of at least approximately located in the plane perpendicular to the axis of rotation of the diaphragm or Belleville springs, or relate to such plane. In some cases it may be preferable if, at least, a separate console plate, at least one segment of their longitudinal extent have a configuration that is offset from the rest of cantilever plates, and this configuration can be obtained or adjusted by the method according to the invention.

For the method according to the invention it is expedient if the heating sections of cantilever plates are heated to a temperature of 600-950oWith predominantly to a temperature of approximately 850oC. the above temperatures are available for diaphragm springs made of steel. Depending on the material can be, however, reasonable and higher or lower temperatures.

The methods according to the invention can find application for the diaphragm spring, i.e., for individual parts, and diaphragm springs, each of which is installed in the node, such as a friction clutch. When using such a diaphragm spring in the friction clutch can be when using the appropriate method fully assembled or partially. For example, the diaphragm spring can be connected to the clutch cover only with the possibility of rotation. Particularly preferably, however, if an appropriate method is used for the fully assembled friction clutches. It is particularly preferred if in the process of editing diaphragm or disc p is and is installed on the vehicle clutch. This can be accomplished by appropriate positioning of the pressure disc with respect to the casing, because this spring is strained.

The preferred way heated areas can be heated inductively. Induction heating can be carried out while rotating part and/or the rotating coil. The coil generates at this alternating magnetic field induces in the details of eddy currents, which cause a rapid rise in temperature. Can be, however, implemented the so-called fire heating, i.e. heating flame.

Particularly useful may be, if required, at least two coils, one heats the parts to edit cantilever plates, and the other is used for heating and quenching of the free edges of the cantilever plates. Due to the very rapid cooling or quenching in the area of the edges of the cantilever plates can achieve a hardness exceeding that available in other parts of the cantilever plates and/or the entire diaphragm spring.

The invention is explained in more detail using the drawings, which depict: - Fig.1 - section; Fig.2-4 - the individual steps of the method or process; - Fig. 5-7 - disc spring, Kotoba according to the invention consists of a bottom 2 and top 3 parts, which can be swapped placed in a closed frame (shown partially). From the entire frame is visible part of the upper plate 4, connected by tie-rods 5 with a bottom plate (not shown). On the top plate 4 is fixed to the upper part 3. The lower part 2 is installed with the possibility of axial movement relative to the upper part 3 by means of an actuator such as a hydraulic cylinder 6, which is only visible to the piston rod. The lower 2 and upper part 3 are connected through the guiding pillars 7 and guide bushings or guide bearings 8 are rigidly, but with the possibility of axial movement relative to each other. The lower part 2 contains the clamping plate 9, loaded by a hydraulic cylinder 6 and the bearing guides support 8. On the clamping plate 9 is installed bearing seat ring 10, which rests axially on the clamping plate 9 and holds the bearing 11, here in the form of a ball bearing. Through the bearing 11 on the clamping plate 9 with the possibility of rotation relative to it by means of a bearing 11 draws the clamping device 12. In the depicted example, perform the clamping device 12 includes at least one annular ring 13, which carries several distributed around the circumference of SAG the form of the centering pins 15, established primarily with the possibility of at least partial axial immersion in the clamping finger, namely, each against the action of the energy accumulator, which can be formed, for example, a spiral spring 16. On the clamping plate 9 or landing ring 10 is, in addition, referential device 17 with referential cylinder 18, which can axially move or load using this plug 19, is assembled from several parts. Using this punch 19 is installed with the possibility of axial movement in the guiding element 20 made here also collected from several parts, and passes without or almost without tipping over. The guide element 20 has a Cup-shaped part 21, which is at least partially placed or covered top referential cylinder 18 and which is firmly connected to the clamping plate 9.

The upper part 3 also contains the clamping plate 22, on which is fixed a bearing seat ring 23 which carries the bearing in the bearing 24 rolling. Through the bearing 24 on the clamping plate 22 axially with the possibility of rotation relative to it based carrier unit 25 consisting of several washers or rotate coaxially to each other. In the depicted example, the execution support device 25 includes a pulley 26 driven in rotation by the belt 27 and the driving motor 28. The device 1 also includes a heating device 29, which is at least partial heating of the cantilever plate parts, in particular a diaphragm spring, and due to the interaction of the heating device and the other parts of the device 1 is provided edit cantilever plates, as is described in more detail below.

In the depicted example, run the heating device consists of a ring-shaped induction coil 29.

The device 1 is used to edit individual cantilever plate diaphragm spring relative to each other, and in this case, the diaphragm spring is a Belleville spring 30 of the friction clutch 31. As can be seen from Fig.5-7, the Belleville spring 30 includes an annular body 32 from which depart directed radially inside the tabs 33, bounding the Central opening 34. Separate the tabs 33 Belleville springs are separated from each other by slots 35, which are radially inside communicated with the Central hole 34, and radially outside pass into the extension 36 in the form of holes, note the 30 corresponds to its fully unloaded state. In the depicted example, perform the tabs 33 Belleville springs bent and radially inner edge 37 of the reeds made dome.

As can be seen from Fig.7, the friction clutch 31 can be installed on the return compression disk, for example, the flywheel 38, and between the return pressure disc 38 and screw-down disk 39 of the friction clutch 31 closes the friction disk clutch 40. Pressure disc 39 load in a known manner by means of disc springs 30. Disc spring 30 in a known manner mounted on the casing 41 of the clutch can be rotated, namely, in the depicted example, the execution of type two shoulders of the lever. Such a friction clutch is known, for example, from US-PS 5301782 and DE-OS 4434019. The invention may, however, find application in the so-called drawing the clutches are known, for example, from US-PS 4909370 and DE-OS 4237623.

Below using Fig. 2-4 described method or process of editing reeds Belleville springs already installed in the friction clutch.

At the first stage of the friction clutch, comprising, at least, of the pressure disc 39, disc springs 30 and the casing 41, is placed in the device 1. In the depicted example, the execution of the friction clutch is placed in owenson 19. Radial positioning or centering of the friction clutch 31 in the example shown, the execution is carried out through the casing 41 of the clutch, provided at its outer edge 42 holes, which includes axially centering pins 15. It is advisable, if provided, at least two centering pins 15. May be envisaged, however, and more centering pins, and may be preferable, if there are three such centering pin, which, as already described, is placed in the clamping elements in the form of clamping fingers 14 with the possibility of axial movement. The number of clamping elements 14 should be at least three, and may be preferable, if there are six such clamping elements, which can be evenly distributed on the periphery.

After placing the friction clutch 31 in the device 1 of the lower part 2 by means of the actuator or cylinder 6 is moved upward, and at first in the upper part 3 of the elastic pressure plate 39 and the centering fonts 15. The emphasis of the individual parts 39, 15 in the upper part 3 can occur virtually simultaneously, or be separated by time. Corresponding to the position shown in Fig.3. When the outlying elements 14, and after passing a certain way these clamping elements 14 rest against the casing or the cover 41 of the clutch. At least then the casing 41 is axially moved in the direction of the fixed pressure to drive until the casing 41 abuts the adjusting element in the form attached to the upper side 3 of the adjusting ring 43. After this, the outer edge 42 of the casing 41 is clamped between the ring 43 and the clamping elements 14. This is the position shown in Fig.4.

It should be noted that the described processes may be fully extended to the desired position using this cylinder 18 or referential punch 19. In this case, when moving the lower part 2 up as soon as the clutch disk 39 is axially rely on the upper part 3, the disc spring 30 is rotated, because it is supported radially on the outside by an axially fixed then the pressure plate 39 and the radially inside in the area of the edges 37 of the reeds loaded using this punch 19. According to other variant when you move the bottom part 2 is up referential cylinder 18 or referential plug 19 may be, however, and in a laid back position and only after the descent of the bottom 2 and top 3 parts referential cylinder 18 or referential point the em to judge the operating condition of the friction clutch.

The final position of the device 1, is necessary to edit the height of the spikes 37 reeds Belleville springs shown in Fig.4. In this operating condition of the friction clutch 31, the tabs 33 of the Belleville springs are pre-strained in comparison with the nominal value of the desired height of the reeds disc springs for a certain amount of about 1.5 mm, This value may be selected, however, more or less. The initial tension should occur, however, in such a way as to ensure the correction of the reeds created by reducing them to Flexural stresses.

In the depicted exemplary embodiment, as already described in connection with Fig.1, the clamping 12 and the base 25 of the device result in rotation of the actuators 27 and 28, and simultaneously or shortly before or immediately after that, activate the induction coil 29, resulting in the neighboring areas 44 of the reeds 33 Belleville springs, at least in some places are heated to the desired temperature, component preferably about 850oC. In the heating strength of the respective plots is very sharply reduced, so that with both of these sections 44 of the segments of the reeds 33 can be lifted to a height between individual spikes 37 reeds or reduce it, at least to an acceptable value. After heating sections 44 and stress relieving with reeds 33 Belleville springs areas 44 can be purposefully cooled, resulting again is hardening sections 44. Cooling sections 44 may be, for example, by using a turbine, directly integrated in the device 1, for example, in the items area, driven in rotation by the actuator 27 and 28. May also be provided a blower or turbine that pumps the cooling air, for example, through the hole 4A in the area of the upper part 3.

In the depicted example, perform an induction coil 29 is turned on from the lid side of the disc springs 30, however, may be located on the other side of the disc springs 30, or on both sides of the disc springs 30 may be provided on one side of the coil.

When performing the above steps, the tabs 33 Belleville springs are pre-tensed in the beginning of the heating sections 44. According to another variant, this is a preliminary voltage may occur, however, only during or immediately after heating sections 44. Depending on the time of loading of the edges 37 of the reeds there is no or p is drop the preset temperature sections 44 have only a very low strength or practically do not have it. A similar result can be achieved, for example, due to the fact that at the beginning of the heating sections 44 referential cylinder 18 or referential plug 19 are retracted position and only after reaching or shortly before reaching the desired temperature deformation him again move up to the position necessary to edit the edges 37 of the reeds.

At the end of the process of editing the rotating parts slow down or stop and the device 1 open, after which the friction clutch 31 can be extracted.

Radial zone, where the heated segments 44 may be selected so that the heating of these segments or sections 44 is at least partially precipitate disc springs 30. This sediment is due to the fact that presented in sections 44 heat effect, at least on the inner edge of the annular body 32 Belleville springs 30. In the process according to the invention can simultaneously occur, therefore, the similarity thermocalc Belleville springs.

According to a not shown in the drawings variant implementation or improvement of the invention, the device 1 may be provided with additional the service hardening of the tip 37 of the reeds Belleville springs get higher hardness, than the hardness of the other sites Belleville springs. Such a coil is shown in Fig.4 and denoted by POS.45. Cooling of the edges of the reeds can be done again by air or otherwise (for example, liquid cooling). Hardening of the edges 37 of the reeds may occur simultaneously with the heating and quenching sections 44 or after or before. Since the hardening of the edges 37 of the reeds using this punch 19 rests on them, especially expedient if this referential punch 19 contains at least one item, for example in the form of washers 19a, from a non-conductive or namagnichivaemost material such as ceramic. The material must have a very low conductivity.

According to one variant of the method or inventions edit reeds 33 relative to each other may also be provided only on a diaphragm or Belleville spring 30 by itself by an appropriate modification of the device 1.

Although the invention is described in connection with the description of figures mainly in relation to the disc springs 30, which has all the edge 37 of the reeds, at least partially provided on the same axial height, the method according to the invention can also be applied to the diaphragm is the tenant, or the edge of the reeds have different heights, i.e. displaced with respect to each other. Such diaphragm spring is known for example from DE-OS 19524827, DE-PS 3643781, DE-OS 3528660, DE-OS 3513315 and DE-OS 2460963.

Research conducted in connection with the invention showed that the hardness of the reeds 33 Belleville springs on inductively heated area 44 can be increased due to a sharp cooling, and may occur a transition zone to the other segments of the reeds 44, which indicates the decrease in the hardness.

Thanks to the method according to the invention separate the edge 37 of the reeds can be displayed on the height with the maximum error0.3 mm relative to the desired reference height. Tests conducted in connection with the invention have shown that can be sustained uncertainty0.2 mm or less.

Because the remaining, possibly, the difference in height or offset edges 37 of the reeds is very small, for example about 0.1-0.3 mm, it is possible according to the improvements of the invention to reduce this bias by mechanical processing such as grinding of the edges 37 of the reeds. This ensures in a friction clutch that when you bring it into action is achieved more uniform input Wuxi, asdastweika on the edge 37 of the reeds of the lever, which is necessary to bring the friction clutch 31 in the action since the bearing is loaded more evenly, and thus the lever is almost no effect of tipping efforts.

Disc springs 30 are subjected to the edit edges 37 of the reeds can especially preferred way to find application in combination with a friction clutch, which contain compensating the wear of the friction lining adjusting device. Such a friction clutch is known, e.g. from DE-OS 4239291, DE-OS 4306505, DE-OS 4239289, DE-OS 4322677 and DE-OS 4412107.

In the described exemplary embodiment the device 1 is so designed that the friction clutch or disc spring rotates, at least during the heating of the relevant sections of the reeds. The device 1 may, however, be so designed that, with appropriate heat treatment of the clutch or disc spring does not rotate, but instead rotate the coil 29 and/or the coil 45, i.e., the heating means.

According to the improvement of the invention when the edit reeds Belleville springs on their edges 37 cannot be installed a pressure element (known, naprimer see the example running. On the contrary, in the framework of the invention, numerous possible variations and modifications, in particular such variants, elements and combinations and/or materials that are inventive, for example, by combination or modification of individual features or elements or process operations described in conjunction with those contained in the General description and the forms of execution, as well as in the claims, and illustrated on the drawings, and through combinable features lead to a new object or to new process steps or the sequence of technological operations, regarding methods of manufacture, and control of technological processes.
