outer ring 2 of tripping bearing 3, and tripping piece
4, which engages with at least three radially mounted rods
5, arranged at equal intervals around the circumference around the sleeve 6 of the diaphragm spring 7 of the coupling. One of the parts of the mechanism has a recess, the other part forms a protruding part, which should include
into the recess with relative axial movement of these parts. The recess has a first part extending from the edge of the part at an angle to the specified axis, and a second part under the shaft to the specified axis. The second part contains the surface of the retainer in order to keep the protruding part with the recess from uncoupling when axial forces of the coupling are applied, the dimensions of the second part are taken in such a way as to ensure in the transverse direction the disengagement of the protruding part to the second part of the recess and subsequent relative movement of the parts. 6 3.p. f-ly., 12 ill.
FIELD OF THE INVENTION The invention relates to automobile construction, in particular to designs of friction clutches.
The purpose of the invention is to increase the reliability of switching the clutch on and off.

The clutch release mechanism (Fig. 1) comprises a release fork part 1, which is fixed rigidly with the outer ring 2 of the release support 3, and the release piece 4, which engages with several, for example, three, radial rods 5, which arranged at equal intervals around the circumference around the sleeve 6 of the diaphragm spring 7 of the coupling.
The clutch release part 4 is formed from sheet metal, which is wound in a cylindrical shape: the sheet to be made is shown in Fig. 2. The part is stamped in the provided form and contains several grooves (recesses) 8-16 for accommodating the rods located between the guide fingers 17-25. Fingers 20-22 (FIG. 3) protrude from the remaining fingers. Finger 17 has two
guide surfaces 26 and 27 converging on guide end 28, which is inserted axially to the left (Fig. 1), in order to place the clutch release detail on Rods 5. Surface 26 enters recess 8, and surface 27 recesses 9. The recess 8 is bounded by the surface 26 and the surface 29 on the finger 25 when the sheet is rolled up in a cylindrical shape. The recesses 8-11 and 15, 16 are identical. The recess 9 is delimited by the guide surface 30 of the finger 18 and the guide surface 31 of the finger 17. Surface 31 lies on the axis of the finger 17 and ends at its guide end on the transverse surface 32 through which the disengagement forces of the coupling can be transmitted. Fingers 17-19, 23-25
are identical.
The finger 22 has two guide surfaces 33 and 34, a guide end 35 and a surface 36 parallel to the surface 33. The recess 14 is limited between the guide surface 37 of the finger 23 and the surface 38 on the finger 22. The surface 38 lies on the axis of the finger 24 and ends at the guiding end on the surface 39, which is bent so as to form part of the holding surface 40, as well as a surface through which the clutch release forces can be transmitted. The fingers 20 and 21 are identical to the finger 22.
The clutch release piece is formed by three equidistant holes 41, in which spacer parts 42 (FIG. 1) of the annular flange 43, which are used to rotate the release piece of the clutch 6 relative to the sleeve 6, are respectively positioned.
The assembly and operation of the clutch release mechanism is carried out as follows.
The clutch release part 4 is mounted on the bearing 3 (Fig. 1) and inserted into the spring hub 6. The device of three successive fingers 20-22 is such that one of them is always in engagement with the rod 5, when the release is moved to the left. In this case, the rod is engaged with the finger 22 so that the subsequent initial engagement of the rod is accomplished by sliding on the surface of the guide end 35 of the finger and sliding either along the surface 33 or the surface 34. If the contact rod 5 slips along the surface 33, the rod will come into the unclearly pronounced end of the recess 13, and the other two rods 5 will simultaneously enter the recesses 10 and 16. If the contacting rod slides along the surface 34, the rod will come to the indistinctly expressed end The depressions 14 and the other rods 5 will simultaneously enter the recesses 8 and 11. The axial movement of the uncoupling part 4 is combined with a slight rotational movement relative to the sliding movement between the surface 33 or 34 and the rod

5 to facilitate the entry of the rods into the recesses. By using three fingers, the release piece 4 is automatically installed with the automatic alignment of the remaining rods with their recesses.
As soon as the rods are located at the unclearly pronounced ends of the respective recesses, the axial movement of the part 4 in the direction of disengagement of the coupling causes the rods to contact the transverse surfaces 32 and 39 at the opposite ends of the recesses through which the disengagement forces can be transmitted to the rods.
The elasticity of the clutch spring 7 will normally hold the rods against the respective transverse surfaces. If any unusually high torque is transmitted through the clutch release mechanism, for example, unexpectedly, the release clutch will have a tendency for the rods 5 to move circumferentially relative to the 4 parts. To prevent the rods from leaving the recesses, the surface on the pin 22 or the like the surfaces on the fingers 20 and 21 prevent such relative movement around the circumference, when the corresponding rod must move in the axial direction with respect to the part 4, overcoming the spring shift of the coupling to free the retaining surface.
In order to remove the clutch release piece 4, the release fork is disconnected from part 1 and removed by spring bias (retracted). Then the release piece of clutch 4 is rotated relative to sleeve 6 by gripping the flange 43 manually, and part 4 after this moving axially so that the rods and recesses will come out of the engagement. The clutch release part 4 can then be completely removed.
The part 1 of the release fork (Fig, 7) is rigidly fixed to the axis with the outer ring of the release bearing 3. The inner bearing ring is fixed rigidly on the axis with the release part 4 of the coupling, which is limited to several recesses 44-46 (Fig, 8). In the recesses
There are several, for example, three radial rods 47, which are located at an equal distance around the circumference around the sleeve 48 of the clutch diaphragm spring (not shown) for an ejector-type clutch.
The upward directed arrow (Fig.8) is a projection of the direction of disassembly, and the location on the right and the downward direction arrow indicate the direction of interconnection and assembly.
The clutch release piece 4 is formed from sheet metal that twists in a cylindrical shape.
The recesses 44 and 45 are limited between the guide pins 49 to 51, each of which has two guide edges 52 and 53, which converge towards the guide end 54. The edge 53 of the finger 50 extends into the recess 44, which has axial direction of the edges 55 and 56, the concave edge 57 to accommodate the rod and the inclined edge 58, the concave edge 57 ends at the holding part 59 (pin 51), the edge 60 passes between the leading edge 52 and the holding part 59 in parallel with the leading edge 53, to limit entry 61.
The elastic guide part 62 is formed from a strip of sheet metal tape in a cylindrical shape and secured with rivets 63 to the inner surface of the cylindrical disengaging part 4. The guide part 62 (Fig. 7) has upwardly wedged parts 64, which protrude through the openings 65 in the disengaging part. The inner ring of the tripping bearing 3 is fixed between the bent edge 66 on the tripping piece 4 and the wedging part 64. The guide piece is formed of three elastically deforming sheets 67 with axial cuts 68 between them. Each sheet has a front surface formed by a sloping edge 69, ending with a locking edge 70, oi-

In use, the release piece 4 is inserted from the front (in the direction A) into the spring sleeve. The pins 49-51 are located on the disengaging part to provide a position in which one of them will engage with the core of the hub. Three sheets 67 are connected with three fingers. Accordingly, the axial movement of the decoupling part causes the rods 4 47 to enter the recesses, one of the rods 47 enter into the recess 44. The inner end of the rod 47 is directed to the slope of the inclined part 71 and the corresponding sheet 67 is deflected inward. Continuing forward movement of the release piece causes the edge 58 and the rod to come into contact with each other, thereby automatically turning the release piece clockwise. The rod engages with the edge 55 and the opposite axial movement in the direction of the unlatching part causes the concave edge 57 to move in the direction of the rod 47.
In order to remove the clutch release piece, the latter is pressed axially again forward, while the edge 69 of the sheet 67 engages with the rod 47. Continuing axial movement causes the edge 69 to be directed along the rod, while automatically rotating counterclockwise the arrows of the unlatching part until the rod and the locking edge 70 are in mutual engagement. The rod is in line with the edge 60 of the finger 49 so that the axial movement of the uncoupling part 4 backwards leads Toi, that the edge 60 strikes and goes along the rod i so that the rod passes through the inlet 60. The uncoupling part 4 can be then completely removed.
The guide piece 72 is formed from a strip of sheet metal rolled up in a cylindrical shape and attached with rivets 73 to the inner surface of the uncoupler.

In use, the release piece 4 is inserted from the front (in the direction A) into the spring sleeve. The pins 49-51 are located on the disengaging part to provide a position in which one of them will engage with the core of the hub. Three sheets 67 are connected with three fingers. Accordingly, the axial movement of the decoupling part causes the rods 4 47 to enter the recesses, one of the rods 47 enter into the recess 44. The inner end of the rod 47 is directed to the slope of the inclined part 71 and the corresponding sheet 67 is deflected inward. Continuing forward movement of the release piece causes the edge 58 and the rod to come into contact with each other, thereby automatically turning the release piece clockwise. The rod engages with the edge 55 and the opposite axial movement in the direction of the unlatching part causes the concave edge 57 to move in the direction of the rod 47.
In order to remove the clutch release piece, the latter is pressed axially again forward, while the edge 69 of the sheet 67 engages with the rod 47. Continuing axial movement causes the edge 69 to be directed along the rod, while automatically rotating counterclockwise the arrows of the unlatching part until the rod and the locking edge 70 are in mutual engagement. The rod is in line with the edge 60 of the finger 49 so that the axial movement of the uncoupling part 4 backwards leads Toi, that the edge 60 strikes and goes along the rod i so that the rod passes through the inlet 60. The uncoupling part 4 can be then completely removed.
The guide piece 72 is formed from a strip of sheet metal rolled up in a cylindrical shape and attached with rivets 73 to the inner surface of the uncoupler.
a snap ring 74 which is in contact with the inner ring of the support 3. The guide part 72
formed with three elastically deformable sheets 75-77, each of which contains two independently elastically deformable sections, which are separated from one another by axial 78 and transverse 79 notches. The first section has an inclined portion 80 bent inward and a concave portion of the edge 81. The second section has an inwardly inclined portion 82 bent in and an edge 83 guiding the rod outwards. The concave part of the notch 79 and the concave part of the edge 83 represent arcs of equal radius relative to a common center.
In operation, three sheets 75-77 are connected with three fingers (two fingers 84 and 85 shown in Fig. 10) with guide edges 83 located in line with the edges of the fingers 86. When the coupling release part 4 is inserted in direction A into the spring sleeve 48, the rod 47 enters one of the recesses, for example, the recess 87, through the inlet between the fingers 84 and 85. The engagement of the inclined edge 88 of the finger 85 with the rod 47 causes the that part 4 rotates clockwise as it moves forward. The rod is guided along the inclined part 80 of the first section, deflecting the last inward until it engages with the concave edge 89 of part 4. The release part 4 then moves in the direction of release of the coupling, as a result of which the rod disengages from the first section, and the latter falls back to its non-deflected position and is directed upwards along the inclined part 82, thereby deflecting the second section inward. The rod engages with the holding rod by the concave edge 90 of the finger 84. The decoupling forces can m transmitted disengaged from the guide member 4 to the sleeve 48 via rods 47.
To remove the clutch release part, the latter moves again in direction A, with the second section sliding under the rod until the latter comes into engagement with the concave edge 81 of the first section. The edge 81 removes the rotation of the uncoupling part 4 in the counterclockwise direction when the latter moves further in the direction of

The SRI A, wherein the rod slides over the guide edge 83 of the second section of the sheet 75. Then the tripping piece 4 moves in the direction opposite to the original one, and the guide lip 83 causes the tripping piece to rotate counter-clockwise, thereby directing the shaft 47 along the edges 83 and 86 to release the finger 84. The release part 4 can then be completely removed.
The first part 91 or 92 of each notch protrudes from one edge of the element defining the notch, n, an angle to the axis of the coupling into which the friction plate is pressed, disengaged from the rotary part of the engine drive, and the second part of the notch 93 including the stopper surface 32, which prevents the protrusion from disengaging from the notch, is angled to an axis larger than the first angle. The end 28 of the part (FIG. 3) usually lies in the same plane as the surface 31.
