    专利说明:

    The invention relates to mechanical engineering, in particular, to devices for transmitting rotation.
    A car clutch is known, comprising a lid mounted on a thrust disk and a friction disk located therein, compressed by a diaphragm spring mounted through supports fixed with rivets on the lid 1,
    The disadvantage of this coupling is the difficulty of fastening the supports with rivets.
    Closest to the invention to the technical essence and the achieved result is a car clutch, comprising: a cover mounted on a stop disk and a pressure disk located in it with axial movement, in contact with a diaphragm spring fixed against axial displacement by a ring mounted on integral with a cover legs containing axial and radial sections, while the lid and ring are made with onopaiMH rings, and the diaphragm spring is located between them. and fixed against radial displacement by the axial sections of the legs 2}. However, the known adhesion has low reliability due to insufficient ring stiffness and high friction in the supports. The purpose of the invention is to increase reliability by increasing ring stiffness and reducing friction in the supports. . The goal is achieved by the fact that in the automobile clutch, which contains a circular wing fixed on the thrust disk and axially displaced the pressure disk in contact with the diaphragm spring, is fixed from axial displacement by a ring mounted on the narrow legs that are integral with the lid, containing axial and radial sections, while the cover and ring are made with annular supports, and the diaphragm spring is located between them and fixed to the axial section from the radial displacement The legs of the legs, the diaphragm spring is located between the supports with a gap, and the axial section of the legs is made with an emphasis, while the ring is fixed between the radial section, the legs and the emphasis.The emphasis is made in the form of projections on the axial section of the legs, and the ring with end-to-end the grooves for the paws. The stop is made with an inclined face, and the ring is with a bent tongue in contact with the said inclined face. The stop is made in the form of a groove in the foot section, and the ring is with a protrusion located in the aforementioned shoulder of the foot.
    The ring is made with stiffeners.
    The ribs are made in the form of consecutive convex and concave sections.
    FIG. 1 shows the clutch according to the G variant; in fig. 2 - partial
    type of ring; in fig. 3 - the same in the future; in fig. 4 is a section A-A in FIG. 3; in FIG. 5 is a section BB in FIG. 3; in fig. 6 shows a section B-B in FIG. 3; in fig. 7 - section G-Y in FIG. 3; in FIG. 8, node I in FIG. 1 5 with clutch engaged; in Fig.9, the same is with the clutch disengaged; on .fig. 10-1 version of the design; on fi. 11 is a perspective view of a part: a lid; according to variant I, one of the lid of the lid is shown up to the bend, its radial part; in fig. .12 - II version of the design; in fig. 13 is a perspective view of a part of the lid according to the P variant, in which one of the tabs of the lid is shown after bending its radial part; in fig. 14.- W option.constructions; in fig. 15 is a perspective view of a portion of the ring according to the W variant; in fig. 16 -: .. 1U variant of the structure) in FIG. 5 17 is a perspective view of a 3/4 ring according to the 1st version; in fig. 18 - 3/4 rings according to the 1U version, rear view; in fig. .19 - U. design variant; in fig. 20 is a perspective view of a part of the lid and ring according to the U. variant, which shows one of the tabs and the linking of the ring with this foot; on. 21 - HS version design; .on FIG. 22 - view in the lane. . From the perspective of a part of the ring, according to the U1, it brews anto which shows a convex zone. of this., is provided at the location of one of the tabs of the lid ...... . . On the peripheral surface of the cover 1 there is a flange 2, with which the cover 1. is fixed to the flywheel 3, by the flange 4 the cover 1 is connected through plates 5 to the pressure disk 6. The plates 5 are rigidly connected. The disk b is attached to the cover in the direction of rotation and is allowed. the disk 6 should have a mobility in the axial direction sufficient for it to operate under the diaphragm. 7. A friction disk 8 located between the flywheel 3. and.nazhimnom.diskom.b, could be sandwiched between them ... ... The diaphragm 7 has a peripheral part 9, which is a spring washer such as a disc spring, in contact with the pressure disk B.J-The central part of the diaphragm 7 is divided into radial fingers 10 slots.11 running from passages 12. to the center. . The release bearing 13 acts on the radial fingers of the radial fingers .10, located in close proximity to the axis of rotation. ... For fastening the diaphragm 7 to the cover 1, an annular support 14 is provided, which in this case is a stamped protrusion, n. cover 1. In the example shown in FIG. 1-9, the means for fastening the diaphragm 7 include a group of circularly arranged with intervals 15 legs, which are integral with the cover 1, the axial section 16 of which passes through the diaphragm 7, through holes 12, and the radial section 17 is located radially and forms a jammed bend 18. The flat and thin legs 16 are cut out in the body of the lid 1 and are properly bent. The fastening means also includes a ring 19, which is formed for the diaphragm 7 by a second bearing surface 20 and located opposite to the bearing surface 14. a cover 1. Support surfaces 14 and 20 are located on a larger radius than apki 15. Support surfaces. 1 and 20 can be formed with intermediate parts. The ring, 19 may have a V-shaped cross section / has a flange 21, which is a continuation of the ring and has a concave shape. In place of each foot 15 on the ring 19 there is a hole 22, through which its axial section 16 passes. The ring 19 has stiffening ribs 23, so as to have good rigidity with a very large thickness. On the ring 19, the flat pad 24 in which the holes 22 are made, the convex portion 25 in the direction of the diaphragm, the concave portion 26 in the direction of the SRI from the diaphragm, the convex portion are also located successively around the circumference. 27 in. Towards the diaphragm, flat again, etc. The axial portion 16 of each tab 15 may have a resistant, stamped protrusion 28 located so. A 4TQ ring 19 is clamped between the zaklin zing 18 and the protrusion. 28 .. This gives the ring 19 greater rigidity and strength, with the result that the supporting surface 20 is fixed, despite the fact that the crown has a small thickness,. . , There is a small gap between the support surfaces of the ring and the diaphragm. The magnitude of this gap J is about one-tenth of a millimeter. When assembling, first cover 1 with unbugs legs 15 is attached. Diaphragm 7 and ring 19 are put on these legs. Diaphragm 7 rests on ring support 14, and veins, tip 19- on projections 28. Section 17 of tabs 15 bends and becomes radial BPL, as a result, the crown 19 is clamped between the resulting - at the same time a wedging bend 1B and a protrusion-ear 28 ... i On the opposite diaphragm, the surface of the crown 19 is clamped. With this clamp, the ring 19 fc is brought together by the diaphragm 7, bringing the gap to its final size and at the same time deforming the legs 15 of the curb 1, bending them. This deformation takes place on a rounding which lies between the annular support 14 and the axial portion 16 of the legs. When the clutch is engaged, the diaphragm 7 is pressed against the annular support 14. When the thrust bearing 13 presses the fingers 10 of the diaphragm 7 in order to disengage the clutch, the diaphragm 7 moves away from the support 14 and presses against the support 20. The gap gives the diaphragm 7 (free adhesion. The protrusion of the axial portion 16 of the tabs 15 can be formed by the shoulders 29 of the axial portion 16. In the second embodiment, the protrusion of the axial portion 16 of the tabs 15 is formed by a notch 30. In 111 of the invention, the protrusion is formed by the inclined face 31 of the axial portion 16 into which a bent tongue 32 of the ring 19 is abutted. In the first embodiment of the invention, the protrusion of the axial portion 16 of the legs 15 is formed by a longitudinal groove 33 in which the protrusion 34 of the ring 19 is located. In the variant of the invention, the protrusion of the axial portion 16 of the tabs 15 is formed by the shoulder 35 19. In this case, the ring 19 is clamped between the jamming bend 18 and the shoulder 35. In the U1 embodiment of the invention, there are extruded portions 36 in the holes of the nozzle position 15. On the crown, the primary support of the lid can be formed by stamping, as shown. .On the drawings as well. also a closed or open ring which is inserted into a groove made in a crown.
