The friction disk of the torsion damping device contains a hub 1 and a base 2 concentrically mounted on it with the possibility of oracularized angular rotation, spring-loaded relative to each other around the circumference by elastic elements 3 (springs). On the hub 1 teeth 4 are made. limit the relative angular rotation of the base and hub. Between teeth 4 and 5 in free state

there is a circumferential gap, which is determined by the uniform action of the elastic elements 3. The latter can be made in the form of tension springs, j, mounted at the ends of the pins of the hub 6 and the base 7, so that only the springs 3 work when the base 2 rotates clockwise the arrow, and others - when it is rotated10 by the SRI counterclockwise. Between the hub and the base, a blocking organ is installed that is sensitive to their angular displacement. FIG. 1 shows two such
15 of the body, installed diametrically. The blocking body is placed in the groove 8 of the base 2 and the slot 9 of the hub aligned with it. The blocking element can be made (Fig.1 and 3) in
20 as a lever 10 fixed through the hinge 11 on the hub 1 with respect to it.
For a swivel with an excitable part of the self-braking
25, the lever 10 comprises a cylindrical circular hinge 11 extending from its corresponding end and entering with a dovetail-type Coupling into the notch 12 of hub 1, along an axis parallel to the axis of the assembly.
The spring plate 13, resting on the base 2, pivots the self-braking lever 10 in the direction of the retracted waiting position at which it rests against
radial shoulder 14 of the hub 1, to transfer the self-braking of the lever lever 10 from the retracted waiting position to the working extended position (FIG. 3), a pusher is associated with it, capable of acting on it when interacting with the tooth. The pusher can be (Figs 1-3) pushing pin 15, which is mounted slid30

drilling in 16, performed in the hub 1, and capable of leaning
on the gear part 5 of the base 2 and on the shoulder 17 a self-brake of the lever 10, which is shifted in the lateral direction relative to its axis of rotation.
Thus, under the control of this pushing finger 15, the self-braking lever 10 is mounted to move with overcoming the force of the spring plate 13, which in this case plays the role of a return device, and with the possibility of reversing this movement between its retracted waiting position and the raised position .
In the retracted waiting position, the self-braking lever 10 is inactive, it provides free angular movement between the hub 1 and the base 2, therefore, the free action of the springs 3. And vice versa, in the extended working position, it provides a circumferential support for the hub and the base, while its free the end, i.e. the end, which is abusive of its hinge axis, abuts against the shoulder 18 provided for this purpose on the base 2 in the groove 8.
When retracted, standby
the circumferential stroke L between the shoulder 18 and the free end of the self-braking of the lever 10 corresponds to the angular gap 1 between the teeth 4 and 5. When the base 2 rotates in the direction of the arrow H (Figures 1 and 3) ca Rev. Ic, the lever 10 remains retracted the waiting position until the relative angular displacement between the base 2 and the hub 1 remains less than the angular play 1.
Conversely, somewhat earlier than the play of the gap 1, the pushing finger 15 moves in the direction of the self-brake of the lever 10 and causes it to turn around it. the axis of rotation in the direction of the arrow F (FIG. as a result, it comes into contact with the shoulder 18 of the base 2,
From now on, if the direction of relative movement becomes the opposite direction indicated by the arrow H (Fig. 3), all the angular movement between the hub 1 and the base 2 is excluded, since the self-braking arm 10 abuts the shoulder 18.
When the time between the base 2 and the hub 1 is reduced to a sufficiently small value so that the teeth and 5 are no longer engaged with each other, the brakes on the lever 10 under the influence of the spring plate 13 return to the standby position.

Friction devices are provided between the self-braking arm 10 and its axis of rotation for delaying the return to the standby position and for
avoiding undue reverse rotation.
For example, between the hinge 11, which is the axis of rotation of the self-brake of the lever 10, and the notch 12 in which this hinge is rotatably mounted, a friction gasket can be inserted.
The actuation of each self-brake of the lever 10 takes place in an analogous manner.
The self-braking levers 10 are triggered when selecting a corner play 3. In some cases, at least one self-braking lever 10 can be provided to operate when the angular play l is selected.
Referring to Figures 4 and 5, the pusher pin 15 enters into the dead end in the corresponding self-braking lever 10 and is elastically deformed. Thus, it is itself a reciprocating device associated with this self-locking lever.
With the operating position of the self-locking lever 10, the pusher pin 15 is subjected to elastic deformation, so that when the lever 10 is released, it elastically returns it to the upward waiting position.
Springs 19 can be used as elastic devices of circumferential action (Figs. 6-12). In this case, the self-braking lever 10 contains two arms 20 located respectively on one and the other side of one of the teeth 4 or 5.
The shoulders 20 (FIGS. 6-9) are separate parts connected to each other by the same rotation axis 21, which intersects the tooth 4, and the self-braking lever 10 also acts on the roller 22 installed in the cutout 23, with its opposite end provided for this purpose, on the periphery of the tooth 4, and capable of being wedged between two shoulders: a beveled 24, made on the tooth 5, and a straight 25, formed by the corresponding profile of the tooth 4, the pusher connected to the self-braking arm 10 is not separable part of it, each of shoulders 20 comprises at a position eccentric relative to the pivot axis 21, the projection 26.
The prong 5 is able to act on the protrusions 26 of the self-braking lever 10 slightly earlier than the choice of the angular play If, since the protrusions 26 in the circumferential direction are slightly ahead of the hubs 1. On the base 2, a bracket 27 is fixed with shoulders that interact with the projections 26 of each of the shoulders 20.
The return devices contain two metal plates 28 forming spring plates attached at one of their ends to the tooth 4 and having a bend at the other end with which they can act on the self-braking arm 10.
The self-braking lever 10 is normally held in the retracted waiting position (Fig. 6). Somewhat earlier, choose the corner play 1, the base 2 by means of the plate 28 begins to act on the protrusions 26 and thereby cause the transition of the braking lever 10 to the extended working position (FIG. 9), in which the roller 22 moving in the notch 23 is wedged between the shoulders 24 and 25 and the base is in a position fixed circumferentially with respect to the hub 1, then the plates 28 retract the self-braking lever 10 to the standby position when the moment is sufficiently small.
The self-braking arm 10 may consist (FIGS. 10-12) of a wire bent into a loop. In addition to the two side arms 20, the wire contains a cross member 29, connecting the side arms 20 and a replacement roller 22,
At the end of the side arms 20, the self-braking lever 10 also comprises two elbows 30, which are simultaneously a protrusion forming a pusher, allowing the self-braking of the lever 10 to swing from the intated waiting position (FIG. 10) to the working extended position (FIG. .eleven).

Each of the knees 30 has at its end angular limb 31, facing one another and forming a rotary axle, providing
5 installation with the ability to rotate the self-locking lever of the lever 10 in the tooth 4.
The middle cross member 29 is an inseparable part of the self-braking device 10 from the rod 10, the latter may abut against the shoulder 18 with its end.
The base (figs. 13-20) is made in the form of a friction disk 32 with two guide washers 33 placed on both sides of the ring 34. The disk 32 of the washers 33 and the ring 34 have aligned windows in which the springs acting in the circumferential direction are installed 35. Stupi2Q ca 1 bears a radial flange 36 associated with it and containing radial grooves and sliders 37 located in them. The grooves are cut-outs 38 in flange 36,
25 and the sliders 37 are slidably mounted in the notch.
In order to radially hold the slide 37, two plastics 39 are attached to it, attached, for example, by welding on both sides of the flange 36,
At the end of each cutout 38, the flange 36 contains a retaining, an emphasis 40.
Against the stop 40, there is a stop 41, which is integrally formed with an axial foot 42, which is attached to the ring 34, the Slider 37 has a surface 43, which limits its radial movement when interacting with the stop 40.
Both sliders 37 have common returning devices associated with them and consisting of a torsion spring 44. The middle part of the spring 44 is designed as a loop 45 located in the plane that surrounds the hub 1. Each branch 46 of this spring is respectively aligned by axial limb 47 (not shown) with sliders 37. 0t- gig 47 enters the channel provided for this in the slide, and passes its end through it.
40
The torsion spring 44 is located 55 on the outer surface of the flange 36. It can also be located between the flange 36 and the friction disk 32.
The torsion spring 44 is located 55 on the outer surface of the flange 36. It can also be located between the flange 36 and the friction disk 32.

From the middle torsion part of the spring YES (Fig. 17), its branches 46 depart.
Each branch 46 of spring 44 forms knee 48, Plastin; 49, for example, are welded to the hub 1 to hold the torsion spring 44 (FIGS. 13 and 14).
To move to the extended position of the sliders 37 (Figures 13-18), the middle torsion portion 45 of the spring 44 is angularly blocked on the hub 1, which it surrounds. Each of the branches 46 of this torsion spring is associated with a shoulder 50, which is designed integrally with the base, with the loop 45 located above the corresponding shoulder 50.
The rigid connection of the hub 1 with the loop 45 of the spring 44 is carried out by fastening it on one side with two protrusions 51 located diametrically and legs (52) (welded to the protrusions),
Each shoulder 50 is made at the end with a foot 53 welded, for example, to a corresponding guide washer 33.
In the absence of blocking bodies, a graph illustrating the action of the clutch corresponds to the graph shown in FIG. 19 (on the abscissa axis is the angular displacement D, on the ordinate axis is the moment C transmitted between the friction disk 10 and the hub 1).
At small values of the moment C, namely at. the dead point, when the car stops, only springs 19 act, which have low rigidity and represent the first degree of depreciation, which can eliminate the dead point noise.
As the torque increases with the implementation of the thrust mode, this first degree of depreciation becomes saturated, and since corner play is selected, the hub ring 34 is directly aligned with the hub 1 at a mixing value DE corresponding to that corner play.
Then the first group of springs 35 comes into play, installed between the guide washers 33 and the hub ring 34, and then successively at D2 values. D3
65 o
the second and third groups of these springs come into effect, right up to the second depreciation stage, formed by a set of springs 35.
For the reverse rotation mode, the CPS / Exists a similar process, only the springs 35 are activated at the same time. However they can
take action sequentially. The springs 19 of the first damping stage act in the dead-point noise filtering zone P, from the angular displacement P1 at the thrust mode to
angular mixing b L with reverse rotation.
When stopping (Fig. 13), the crawlers 37 occupy an inactive standby position at which they are inactive, thus ensuring the freedom of action of the springs 19, and everything happens as if I had an angle offset DJ, D schedule, reproducing action
friction, also included the angular displacement (Fig.19, a solid line - in the filtration zone P, the dotted line - outside).
For operation in the pull mode and as the corresponding angular mixing between the hub 1 and the friction disk 32, the shoulders 50 push off the knees 48 of the branches 46 of the spring 44, and under the influence of this force the branches gradually cause the radial movement of the sliders 37 along their guides.
At an angular displacement, the DJ sliders 37 occupy an extended working position, in which (FIG. 18) they radially abut their surface 43 against the holding stops 40 and lie between the stops 41,
If the device moves from the pull-in mode to the reverse-rotation mode, the stops 41 overlap the sliders 37 and the hub ring 34 is thus fixed in the circumferential direction through the axial stops 41, the sliders 37 and the flange 36 without reverse angular displacement between the ring 34 and the hub, and therefore without noise. In this case, the springs 19 of the stage of low severity are inactive;
On the graph, which reproduces the corresponding action (Fig. 20), the filtering zone P of the dead point noise is excluded.
Thus, everything happens as if only the springs 35 of the first friction stage would act to filter the draft or reverse rotation.
If the circumferential distance L corresponds exactly to the angular backlash 1, the springs 35 are released during reverse rotation at the abscissa point Df, if the distance L corresponds in an angular ratio to a value less than the angular displacement I, it is at the abscissa point below the point Dt.
In this case, the play can exist in the circumferential direction between the sliders 37 and the stops 40, the sliders 37 are supported on the flange 36 due to the clearance in the cut-out 38 of the flange 36. The sliders 37 can contact in the circumferential direction with the stops 40, which in this case are double function of circumferential and radial restriction of plate movement.
At small moments, when the angular displacement between the hub 1 and the disk 32 again becomes less than the angular displacement corresponding to the point on the abscissa DE, the sliders 37 emerge from the axial legs 42, move away from contact with the stops 41 and gradually stand to the standby position through the branches 46 of the torsion spring 44, with which they are coupled.
The slides 37 are supported on the flange 36 through the side surface of the corresponding notch 38.
Between the sliders 37 and the notches 38 in which they slide, friction devices are provided to delay the return of the plates to the standby position (not shown).
Between the sliders 37 and the base can be made cam with. 21-23, which comprise a finger 54 fixed on an angle 55, rigidly connected to the stop 41, and an opening 56 with a beveled side 57 made in the slider 3. A finger 54 is placed in the opening 56, resting on the bevelled side 57 of this hole.
Hole 56 has a circumferential pad 58 at the end of its bevelled side 57.
17265 12
As the angular displacement is associated with the sliders 37. the fingers 54 cause the latter to radially move, guiding them to choose 5 nN-angle play 1 in the position in which they enter between the stops 40 and 41 (Fig.22).
If the angular misalignment continues, the fingers 54 follow the circumferential pads 58, not interfering with the device.
On Fig and 25, the base 2 and the hub 1 is shown only approximately. The blocking body is a slider 59, mounted with the possibility of radial sliding in the guides 60 rigidly connected to the base 2. The rim 61 is connected to the hub 1 and has an opening 62. On the 20th surface of the step, s1 has a cam profile 63, capable of pressing the slider 59 in the direction of the hole 62.
The guides 60 (Figs. 26 and 27) 25 are connected to the hub 1, while the rim 61 is fixed to the base 2.
The guides 60 and slider 59 (Figures 24 and 26) are at some angular distance from the hole 62 and from the cam profile 63.
When the angular displacement between the hub 1 and the base 2 slider 59 is against the hole and pushed by the cam profile 63, which is a practically simple bevel, it enters this hole (Figure 25).
From this moment on, the hub 1 and the base 2 are fixed relative to each other circumferentially through the guides 60, the slider 59 and the rim 61.

In order to retract the slide 59 into the resting position when the angular displacement between the hub 1 and the base 2 again becomes smaller than the value of DJ, the return means are provided.
Between the slider 59 and the guides 60, friction devices are provided to delay the return of the slider to the rest position.
In all the described embodiments, the blocking organ or organs are sensitive to centrifugal force, and this force can have a positive effect on them at sufficiently high speeds, in particular, to maintain them in the working position.
13
Their transfer from the retracted waiting position to the retracted working position is carried out irrespective of the speed of rotation. It can be carried out at speeds that are insufficient for centrifugal force to have a noticeable effect.
The device can be put into operation not only during the transition from
/ -X /
21726514
press gi to reverse rotation mode, but also in the transition from reverse rotation to thrust mode.
5 The use of the device will improve the operating conditions of torsional shock-absorbing elements by reducing shocks during reversal and rotation and low torques.
