in fig. 1 in the disconnected position of the ring element; in fig. 18 - clutch release bearing assembly (option), axial section.
The clutch release bearing assembly contains a release bearing 1 for disengaging the clutch (shown schematically with a dashed line in Fig. 1) in the form of the ends of the radial fingers of the diaphragm, which is part of the clutch disabling device 2 and contains a continuous circular peripheral part (not shown) that forms a disk springs for engaging this clutch, as well as the central part, which is divided into radial fingers by notches (not shown) to form levers capable of controlling its disengagement is
In order to connect the clutch release bearing 1 with the clutch release device 2, which is necessary for pulling the release bearing 1 onto the clutch release device 2, the joint part 4 is inserted through its central hole 3 into the latter.
On the side of the clutch release device 2 opposite to the release bearing 1, the docking piece 4 comprises a radial support flange 5 for acting on the clutch release device 2. The support flange 5 has a corresponding profile for this purpose. Integrally along the axis of the sleeve 6, which is connected to the support flange 5 by means of a smoothly rounded fillet and intersects the disengagement device 2 axially, the passage through its central opening 3 is integrally formed with the flange 5. On the other hand, at its outer peripheral part in separate places along it, the docking piece 4 has legs 7, which also intersect axially the clutch release device 2, each of the legs located between its two adjacent radial fingers (not shown). Each of the claws 7 is provided with circumferentially fastened fingers at the end of the foot 7 (to the right of the support flange 5 and parallel to it) holding fingers 8, providing axial mounting of the release bearing assembly on the clutch release device 2.
The installation on the site of the connecting part 4 on the clutch release device 2 is performed by mounting the bayonet type: after sufficient relative approaching of the joint part 4 and the clutch release device 2, axially relative deflection is ensured.
with respect to the other ends of each of the radial fingers of the clutch device 2, with which the holding finger 8 must come in contact with the circumference
legs 7 of the docking part 4. Then provide a relative rotation around the axis of the node of the docking part 4 with respect to the clutch deactivation device 2 in order to engage,
0 and then free the previously bent fingers.
The axial sleeve 6 of the docking part 4, which is made of sheet material, for example of a stamped sheet, has
5 in its middle zone between two cylindrical sections 9 and 10, section 11 of a conical shape. The cylindrical section 9, which is most distant along the axis from the support flange 5, has a smaller diameter than
0 another section 10.
At the free end of the cylindrical section 9 of smaller diameter along the inner peripheral part there is a beveled edge forming the conical surface of the inlet 12:
The release bearing 1 has an acting element 13, with which it can act on the clutch release device 2 by means of the docking part 4, a control element 14 by which the bearing 1 is mounted with axial sliding on any guide element (not shown) , made, for example, in the form of a pipe protruding on the carriage of the velocity box, as well as connecting means, which are fixed in the axial direction of the acting element 13c by the control element 14 and by means of
0 of which it can be actuated by a control body 15, made, for example, in the form of a clutch switch fork 16.
In the presented forms of implementation
5, the actuating member 13 comprises a ball bearing.
In order to interact with the docking part 4, it comprises a sleeve 17 - an actuating part.
0 The operating part 17 is connected to the inner ring of the ball bearing, and for this purpose this ring has a rather long axial continuation in the direction of the deactivation device 2
5 clutch.
The control element 14 contains in the axial direction a guide sleeve 18, with which it can be mounted with a clip on the corresponding guide element (not shown), and
in the transverse direction, at the end of the sleeve 18 opposite to the acting member 13, the member 14 comprises an annular flange 19 for interacting with it.
On the outer peripheral part of the ring flange 19 there is a protruding rim 20, which is located coaxially with the guide sleeve 18 and in the same direction around the outer ring 21 of the ball bearing of the acting element 13.
In the presented embodiments, a self-aligning release bearing with a constant self-centering is used, in which a free annular gap is left between the rim 20 and the ball bearing forming the acting element 13.
The connecting means that axially attach this acting element 13 to the controlling element 14 are made in the form of a casing 22, which with its skirt 23 is placed without a gap on the rim 20 of the controlling element 14.
At the axial end of the skirt 23, located on the side of the clutch release device 2, the casing 22 has a bent edge 24 in a radial direction to the axis of the assembly, on which the outer ring 21 of the ball-bearing of the acting element 13 rests with its respective end.
On the other axial end of the skirt is 23 casing
22 forms, for the action of the fingers of the control body 16 in the form of a sleeve 17, two brackets 25, which, in positions diametrically opposed to each other, project radially in the direction opposite to the axis of the assembly, i.e. to the periphery.
Between the casing 22 and the control element 14, means are provided that are capable of fastening the casing 22 axially with the control element 14, such as snap-in means. Moreover, elastically deformable tabs are provided for this purpose in the rim 20 of the control element 14 for engaging with the holes also provided for this purpose in the skirt
23 housings 22.
In addition, since a self-centering release bearing with constant self-centering is used, elastic means with axial action are provided between the acting element 13 and the control element 14, for example, as shown in the drawing, the corrugated washer 26.
The corrugated washer 26 rests on the annular flange 19 of the control element 20 and acts on the corresponding end of the outer ring 21 of the ball bearing of the acting element 13, pressing the outer ring against the bent edge 24 of the case 22.
A rigid coupling means is installed between the acting part 17 of the release bearing 1 and the docking part 4 located on the clutch release device 2 for sensing forces capable of providing axial coupling between said parts in the axial direction, which is shown schematically in fig. 1 by the arrow, coming from the clutch release device 2 to the release bearing 1.
Since the docking part 4 contains in the axial direction of the sleeve 6 and it is located coaxial to the acting part 17, between the sleeve 6 and the acting part 17 there are installed means for creating a rigid connection for sensing the effort.
The actuating member 17 enters the inside of the sleeve 6 of the docking part 4 so that the means for creating a rigid connection for sensing forces act between the outer peripheral part of the acting part 17 and the inner peripheral part of the sleeve 6.
In the general case, they contain (Fig. 1 and 2) an annular communication element 27, which is located on one of the parts 4.17, intended to create a rigid connection, and is elastically deformed in the radial direction. The gripping shoulder 28, which is made in the transverse direction on another of the parts 4, 17, is arranged to interact with the annular connection element 27 in the axial direction, indicated by the arrow in FIG. one.
The annular communication element 27 is located at the docking part 4, and therefore the corresponding gripping shoulder 28 is formed on the acting part 17.
The gripping shoulder 28 is part of one of the lateral sides of the annular recess 29, which is formed on the outer surface of the acting part 17.
This side, which is straight, perpendicular to the axis of the assembly, is rotated towards the governing body 15 and, therefore, towards the annular flange 19 of the control element 14, goes near the end of the acting part 17 and has a recess 30 at the base.
At its end, the acting part 17 comprises a cylindrical portion 31 on the outer peripheral part.
a shoulder 28 and connected to a cylindrical portion 31, which extends axially, a tapered entry portion 32.
The diameter D4 of the cylindrical section 31 is somewhat smaller for assembly purposes than the diameter D2 of the inner peripheral part of the cylindrical section 9 of a smaller diameter of the sleeve b of the connecting part 4.
The annular communication element 27 may be made of round wire, respectively, twisted and formed.
For elasticity, this element is locally cut by a slot 33 extending in the radial direction (Figs. 10 and 11).
Locally, it contains at least two legs 34 and 35, each of which extends in a radial direction.
The tabs 34 and 35 are diametrically opposed to each other, and both of them run in the direction opposite to the axis of the entire assembly, i.e. to the periphery.
Each of the legs 34 and 35 is formed by a local deformation in the form of an arc of the ring element 27 of the connection and lies in the plane of the main ring part 36 of the element 27 of the connection.
Each of the legs 34 and 35 has a middle part, respectively, 37 and 38, which, being co-aligned with the main part 36 and shifted relative to its radius, passes around the circumference, as well as two straight end portions and 39 and 40 located each at the ends of the arcs middle parts 37 and 38 to ensure its communication with the main part 36, which, being parallel to one another, extend parallel to the median plane of the entire assembly passing through the middle zone of the middle parts 37 and 38.
Slot 33 is made in the middle part 37 of the arc, forming one of the legs 34, and dividing it into two sections 41 and 42, each of which extends as a cantilever, counting from the corresponding end part 39.
In addition, each of the sections 4.1 and 42 of the middle part 37 of the tab 34, cut by the slit 33, at its free end, i.e. at the end opposite to the corresponding end part 39, continued from - - bend 43, 44, which, together with another bend, may facilitate the application of a pushing force to the ring element 27.
The bends 43.44, which has a ring element 27, are arranged parallel to its axis and perpendicular to the plane of its main part 36, each of which has the shape of a half wave, and their depressions are facing one another.
The main part 36 of the annular communication element 27 is located inside the sleeve 6 of the connecting part 4.
The tabs 34 and 35, which, mainly radially, pass through each sleeve 6 of the connecting part 4 using the recesses 45 and 46 provided therein, can interact, resting at least one of their sections on
a guide portion 47.48 belonging to the guide surface 49 coaxially with the sleeve 6.
The guide surface 49 can be made conical and belongs to
the surface of the sleeve 6 of the docking part 4, opposite to that along which the main part 36 of the annular communication element 27 extends circumferentially.
The surface 49 is the outer surface of the sleeve 6 and is formed by the outer surface of its conical portion 11.
Since the docking part 4 has a constant thickness, in the presented embodiments, the taper of the guide surface 49 is equal to the taper of the corresponding inner surface 50 of the conical section 11 of the sleeve 6 of the docking part 4, which is its surface,
with which the main part 36 of the annular communication element 27 should interact.
The middle portion 37, 38 of the tabs 34, 35 of the ring element 27 interacts with the guide surface 49, more precisely with the corresponding guide portions of this surface 47, 48.
For each of the tabs 34, 35 of the annular element 27, the EI of the sleeve 6 of the connecting part 4 contains two notches 45 and 46, each of which is located respectively on one and the other side of the respective guide section 47 and 48 and extends axially parallel to it. one notch
for each of the end portions 39 and 40 of the tabs 34 and 35.
The notches 45 and 46, mainly made in the conical (main) section 11 of the sleeve 6.
For the foot 34, i.e. For the one that is cut by the slit 33, there are two separate recesses 45, which are extended not only along the axis, but also along the circumference.
In addition, each of the grooves 45 on
the end of the arc opposite to the guide section 47, to which they are adjacent, is extended by an axial section 51, which extends not only to the cylindrical section 10 of a larger sleeve diameter
b, but also extends onto the support flange 5, which is a continuation thereof;
For the tab 35 of the ring organ 27, i.e. For that of the legs, the middle part 38 of which is continuous, two notches 46 of the sleeve 6 of the connecting part 4 are connected to one another in the form U at the end of the guide section 48 to which they adjoin the common rounded part 52 for them.
They also extend onto the cylindrical area of larger diameter 10 of the sleeve 6 of the connecting part 4 in the axial direction to the area adjacent to its supporting flange 5, but do not exit from it.
The guide portion 48, with which the middle part 38 of the tab 35 of the ring element 27 communicates, belongs to the tab 53, which is cut in the sleeve 6 of the joining part 4 and extends in the form of a cantilever, counted from its supporting flange 5.
The guide surface 49 continues with a cylindrical rest surface 54 capable of supporting the annular connection element 27 in the separation configuration and being the outer surface of a cylindrical portion of larger diameter 10 of the sleeve 6 of the connecting part 4 having an OB diameter (see Fig. 2).
The axial extent of the cylindrical rest 54, associated with the surface of a cylindrical section of a larger diameter 10 of the sleeve 6, is explained by a smooth rounding (fillet), by which it is connected to the supporting flange 5.
The annular communication element 27 is installed in advance on the docking part 4, which itself is intended to be pre-installed on the controlled clutch release device 2.
For installation on the docking part 4, an annular communication element 27, set obliquely, from the side of the supporting flange 5, first with its foot 35 is inserted into the middle circular connecting part 52 of the notches 46 of the sleeve 6 with the Lagsy 35 engagement for the corresponding tongue 53. Then it rises again and The bends 43, 44 of its legs 34, one after another, are inserted into the corresponding recesses 45 of the sleeve 6.
From this moment on, the annular element 27 of the connection with the middle part 37, 38 of its legs 34, 35 acts on the guide portions 47, 48 of the connecting part 4.
Due to the taper of the guide surface 49 and the intrinsic elasticity of the element 27, the latter, being released, moves along the corresponding conical section 11 of the sleeve 6 of the connecting part 4 until it reaches in position
the rest (Fig. 12) of the region near the end of the conical section 11 adjacent to the cylindrical section of smaller diameter 9 of the sleeve 6.
For a corresponding configuration 5 of the rest, the ring element 27 of the communication, moreover, elastically acts by the middle part 37, 38 of its legs 34, 35 on the corresponding guide portions 47.48 of the connecting part 4, more precisely its sleeves 6.
0 At the same time, with its main part 36, it is in contact with the inner surface 50 of the corresponding conical section 11 of the sleeve 6 or at least close to it, with the end
5 plots 39.40 paws 34, 35 were installed respectively.
Due to the support of the middle part 37, 38 of the tabs 34, 35 of the annular element of the communication 27 to the guide portions 47, 48 coaxial with
0 by the sleeve 6 of the docking part 4, the annular communication element 27, or rather its main part 36, is correctly centered relative to the sleeve 6, taking into account the gap necessary for its installation.
5 The main part 36 of the ring element 27 is therefore appropriately centered about the axis of the entire assembly, in particular with respect to the acting part 17 of the release bearing 1.
In addition, with their paws 34, 35, the ring element 27 is properly held axially within the axial deflection of the connection piece 4 and is not
5 need to provide for some other design to limit its axial deflection on this part.
DI and DI - respectively, the outer and inner diameters of the main part 36
0 of the annular element 42 in its resting position (Fig. 12).
The diameter DI is greater than the diameter Da of the inner peripheral part of the cylindrical section 9 of a smaller diameter of the sleeve
5 6 docking part 4, the diameter DI is smaller than the diameter DS of the cylindrical section 31 of the acting part 17 of the release bearing 1.
Therefore, if (see Fig. 12 and 13)
0 The release bearing 1, under the action of, for example, the control body 15, enters with its acting part 17 into the sleeve 6 of the docking part 4, then it is the conical insertion section 32 with its acting
5, the part (sleeve) 17 is joined (FIG. 13) with the annular communication element 27, more precisely with its main part 36.
However, during this docking, the annular communication element 27 is correspondingly centered relative to the acting
parts 17, and docked around the circumference without the risk of skewing.
Since the insertion movement of the release bearing 1 continues (Fig. 14), the annular coupling element 27 is simultaneously entrained in the axial direction by the acting part 17 and deformed by it in the radial direction under the action of its insertion portion 32, which is made conical for this purpose.
The radial direction of the main part 36 of the annular element 27 is pushed against the inner surface 50 of the conical section 11 of the sleeve 6 of the connecting part 4, following this surface in the direction of its supporting flange
five.
At the same time, with its middle part 37, 38, the tabs 34, 35 of the ring element 27 remain substantially in contact with the respective guide portions 47, 48 of the connecting part 4.
When (Fig. 15) the insertion of the release bearing 1 is sufficient for the gripping shoulder 28 located on its acting part 17 to cross the main part 36 of the annular communication element 27, then it itself tends to return to its initial rest configuration and enters in the radial direction the main part 36 in the annular recess 29 of the acting part 17 of the release bearing 1.
Consequently, if (see arrow in Fig. 16) an axial movement is applied to this bearing 1, the opposite of the one discussed above, using, for example, the control member 15, then the annular coupling element 27, or rather its annular main part 36, is trapped between gripping shoulder of the acting part 17 of the release bearing 1 and the inner conical surface 50 of the sleeve 6 of the docking part 4.
The required connection or grip is provided if, according to the arrow in FIG. 1, which corresponds to the arrow in FIG. 16, the thrust action is applied to the release bearing 1 by the control body 15, this thrust action is transmitted to the disengagement device 2 sequentially through the annular coupling element 27, the engaging shoulder 28 and the docking part 4, the inner conical surface 50 of the sleeve 6.
A sufficient mounting gap (not shown) is provided between the annular communication element 27 and the docking part 4 so that, during operation, this part can effectively follow the deactivation device 2 in its possible deformations.
To disengage, the clutch can be operated manually by, for example, a tool allowing the bends to be spread out 43.44 of the ring 27. As shown in FIG. 17, the annular communication element 27 is then located on the cylindrical rest surface 54,
provided for this at the docking part 4, and for the disclosed configuration, which it then adopts and which forms for it a clutch release configuration, the detail 17 can move away from the main annular part 36 of the element 27.
To disengage the clutch, as an option, an annular clutch disengaging element 55 capable of causing the annular element 27 to be implemented
connection, go from its configuration of the connection, or configuration of rest, to the configuration of separation, allowing it to release the acting part 17 of the release bearing 1.
As shown in FIG. 18, this annular separation element 55 is mounted axially movable in the annular recess 29 of the actuating member 17. The actuating member 17 of the release member
The bearing can be formed both by the inner ball bearing ring that is contained in this release bearing and by the outer ball bearing ring.
In addition, the acting part 17 may not be integral with the ball bearing ring, but also simply connected axially to it.
The annular communication element 27 preferably contains only two legs 34 and 35, but may also be provided with a large number of such legs.
The tabs 34 and 35, which contain the ring element 27, are not necessarily the result of its local deformation along an arc, but may, for example, attach to its core and / or have some other configuration or composition.
The tabs 34 and 35 may also interact with the guide surface 49 coaxially with the sleeve of the connecting part 4, not the middle part, but another part that is adjacent to the middle or not adjacent.
The guide surface 49, alternatively, may be not conical, but, for example, cylindrical, in which case it is preferable to have a shoulder 28 on the side of the supporting flange 5 for limiting
in this direction the possibility of axial movement of the ring element 27 of the communication.
