Description

  The present invention relates to a clutch damper disk assembly having multiple friction members, and more particularly, to connect a first friction member in contact with a flange of a hub and a second friction member in contact with an intermediate disk member so as to rotate together. The present invention relates to a clutch damper disk assembly having multiple friction members that use a first pressure member.

  Power from the automobile engine is transmitted to the flywheel via the crankshaft, which is received by the disc pad of the clutch disc assembly, but the engine is operating even when the gear is in the neutral state, so the vibration caused by this causes the disc pad to vibrate. The noise is transmitted through the entire clutch disc assembly. In order to solve this problem, a structure that generates friction in the clutch disk assembly is adopted.

  FIG. 18 is a perspective view of a multiple friction member used in a conventional clutch damper disk assembly. As shown in FIG. 18, the multiple friction member 40 used in the conventional clutch damper disk assembly includes a second friction member 45 for connecting the first friction member 41 and the second friction member 45. A groove 46 is formed on the inner diameter side, and a protrusion 42 that engages and engages with the groove 46 is formed on the outer diameter side of the first friction member 41. Then, the first pressure member 50 is placed on the upper surface of the first friction member 41, and the second pressure member 52 is placed on the second friction member 45 via the protrusion 47 of the second friction member 45. Is arranged.

  This includes a first friction member 41 provided so as to be in friction with a hub flange engaged with and engaged with an output shaft that receives power from the clutch disc assembly, and an intermediate disc member provided inside the input side disc member. The second friction member 45 provided so as to rub is provided separately.

  In the damper disk assembly having such a multiple friction member 40, the torsional vibration having a small amplitude is attenuated by the friction of only the flange of the hub and the first friction member 41, and the vibration having a large amplitude is the same as that of the intermediate disk member. The two friction members 45 generate friction and perform a killing action.

  The first pressure member 50 provided on the first friction member 41 has a structure that is not limited in movement with respect to the first friction member 41 and can freely rotate. Therefore, when the torsional vibration is transmitted, there is a problem that the first pressure member 50 forms a friction surface while sliding with respect to the first friction member 41. As a result, it means that the originally intended friction between the first friction member 41 and the hub flange does not occur correctly.

  Thus, there has been a problem that the friction coefficient associated with the friction surface changes due to the change of the friction surface, and thus the torsional vibration transmitted from the engine cannot be properly reduced due to the reduction of the reduction effect.

  If such a situation continues, a problem arises in that a rattling noise called a neutral rattling sound is generated while teeth of the transmission gear and the like collide with each other with the vehicle gear positioned in a neutral position.

  In the manufacturing process of the clutch damper disk assembly, first, the multiple friction member 40 is assembled, and the assembled multiple friction member 40 is assembled to an input side disk member (not shown).

  The conventional multiple friction member 40 has a structure in which the first friction member 41 and the second friction member 45 are directly engaged with each other, and the protrusion 42 of the first friction member 41 has the structure of the second friction member 45. It was placed in a groove 46. However, since the protrusions 42 of the first friction member 41 are merely arranged in the grooves 46 of the second friction member 45 and are not fixed or constrained, the multiple friction member 40 is used as the input disk member. When an impact or vibration occurs during the assembly process, the protrusion 42 of the first friction member 41 easily disengages from the groove 46 of the second friction member 45, and the protrusion 42 of the first friction member 41 becomes the second friction. There has been a problem in that the member 45 is frequently detached from the groove 46 and assembled.

  The present invention has been devised to solve the above problems, and a first object of the present invention is to engage and engage the first pressure member with the first friction member, and The first pressurizing member is engaged with and engaged with the second friction member, and the first friction member and the second friction member are rotated together through the first pressurizing member. A clutch damper disk assembly having a friction member is provided.

  Further, it is more desirable that the engagement groove (27) formed on the inner diameter side of the first pressure member (25) is uniformly formed on the entire inner diameter.

  In addition, the insertion part (28) of the first pressure member (25) is spaced apart from the outer diameter of the first pressure member (25) by at least the width of the second protrusion (22). Most preferably, the guide pieces (29) are formed by protruding.

  Most preferably, the first and second friction members (11) and (20) are molded from synthetic resin, and the first and second pressure members (25) and (30) are made of a metal material.

  And as one viewpoint of this invention, it can adapt that the protrusion height of the 2nd protrusion (22) of a 2nd friction member is lower than the protrusion height of a 1st protrusion (21).

  The protrusion height of the second protrusion (22) of the second friction member is lower than the protrusion height of the first protrusion (21) and is equal to or greater than the thickness of the first pressure member (25). Is most desirable.

The clutch damper disk assembly having multiple friction members according to the present invention is further arranged on the inner side of the input side disk member (1) to which torque is inputted and the input side disk member (1), and on the outer periphery with the flange portion (6 ) Formed on the hub (5), the intermediate disk member (7) disposed on the outer periphery of the hub (5), and the rotation between the intermediate disk member (7) and the flange portion (6). A first elastic member (9) arranged to restrict and a second elastic member (9) arranged to restrict relative rotation between the input side disk member (1) and the intermediate disk member (7). In a clutch damper disk assembly having a multiple friction member comprising an elastic member (8),
A first friction member (11) disposed in contact with one side surface of the flange portion (6) and having a plurality of engagement protrusions (14) formed on the outer periphery upper end;
A second friction member (20a) which is disposed in contact with one side surface of the intermediate disk member (7) and has a protrusion (21) which engages with the input side disk member (1) on the upper surface;
A plurality of insertion portions (28) that engage with the protrusions (21) of the second friction member (20a) from the side are formed on the outer periphery, and the engagement protrusions (14) of the first friction member (11) are engaged. A plurality of engaging grooves (27a) are formed on the inner periphery, the outer periphery is supported by the input disk member (1), and the inner periphery is a cone spring supported by the first friction member (11). A first pressure member (25a);
A second pressure member (30a) which is a cone spring disposed on the upper surface of the second friction member (20a) and supported up and down by the input side disk member (1) and the second friction member (20a). )
The protrusion (21) of the second friction member (20a) engages with the insertion portion (28) of the first pressure member (25a), and the second friction member (20a) and the first pressure member ( 25a) and the first pressurizing member (25a) and the engaging groove (27a) are engaged with the engaging protrusion (14) of the first friction member (11). The pressure member (25a) and the first friction member (11) rotate integrally.

  Then, in order to prevent the first pressure member (25a) from being detached, the engaging protrusions (14) of the first friction member (11) are further formed with locking protrusions (15) protruding outward. The engagement groove (27a) of the first pressure member (25a) can be disposed below the locking projection (15).

  Note that the insertion portion (28) may be bent so that the outer periphery of the first pressure member (25a) contacts the input-side disk member (1).

  According to the clutch damper disk assembly having the multiple friction member having the above-described configuration, the first pressure member engages with the first friction member and moves integrally without relative movement. A friction surface is not formed between the first pressure member and the first friction member. Therefore, there is only one friction surface between the first friction member and the hub flange. Such a friction between the first friction member and the flange surface of the hub promotes a smooth decrementing action, thereby canceling the torsional vibration transmitted from the engine and reducing gear noise generated in the transmission. There are advantages.

  In addition, because the first friction member is engaged with the projection, the first pressure member engaged therewith does not flow separately, and even if an impact or vibration occurs during the assembly process of the clutch damper disk assembly, it is assembled first. There is an advantage that there is no risk of losing the first pressure member from the multiple friction member. On the other hand, the first friction member is engaged with the first pressure member via the locking projection, It is possible to prevent the first friction member from falling down and being lost.

  Since the protrusion of the second friction member used for the engagement between the input side disk member and the second friction member can also be used when the second friction member and the first pressure member are engaged. There is an advantage that it is not necessary to form an additional engagement structure.

  A large frictional force is generated by setting the pressing force of the second pressing member to be larger than the pressing force of the first pressing member. At this time, the torsional vibration having a large displacement angle is generated due to the characteristics of large rigidity and large frictional force. Effectively diminish. Here, when a large frictional force is generated, the wear of the second friction member becomes relatively faster than that of the first friction member. Accordingly, the first friction member and the second friction member need to move relative to each other in the axial direction. In the present invention, such relative movement in the axial direction is enabled by the engagement between the protrusion of the second friction member and the insertion portion of the first pressure member.

  The present invention has a structure in which the first protrusion of the second friction member is connected to the input side disk member, and the insertion portion of the first pressure member is restrained by the second protrusion of the second friction member. Therefore, even if the first friction member moves in the axial direction with respect to the second friction member, the first friction member does not move in the circumferential direction with respect to the second friction member. The friction member and the second friction member have an effect that the original position is not always removed.

  The insertion portion of the first pressure member is inserted into the second protrusion on the upper surface of the second friction member and disposed horizontally on the upper surface of the second friction member, and the outer diameter of the first pressure member is There is an effect of generating sufficient pressurizing force without causing almost any deformation by contacting the input side disk member.

It is sectional drawing which shows the part incised. As shown in FIGS. 9 and 10, the first pressurizing member 25 of the multiple friction member 10 according to the present invention has a truncated cone spring portion 26 and an equal interval on the inner diameter side of the cone spring portion 26. And a plurality of semicircular engagement grooves 27 formed. In particular, the engagement groove 27 is uniformly formed over the entire circumference of the inner diameter in order to reduce the ease of assembly, that is, the necessity of accurately adjusting the rotational position. For example, 16 engagement grooves 27 can be formed for an inner diameter of about 40 mm.

  A plurality of insertion portions 28 extending outward are formed at equal intervals on the outer diameter side of the cone spring portion 26. The insertion portion 28 is provided so as to be spaced apart by a pair of guide pieces 29, and the pair of guide pieces 29 are formed by bending the outer diameter side of the cone spring portion 26, whereby the input side It contacts the disc member 1 horizontally.

  FIG. 11 is a plan view of the second pressure member 30 of the clutch damper disk assembly having multiple friction members according to the first embodiment of the present invention, and FIG. 12 is taken along the line EE of FIG. It is sectional drawing which shows the part incised. As shown in FIGS. 4, 11 and 12, the second pressure member 30 of the multiple friction member 10 of the present invention has a truncated cone spring shape and is radially outward on the outer diameter side. A plurality of projecting pieces 31 extending to are formed. There are about 16 such protruding pieces 31 when the outer diameter is about 5.5 cm.

  Hereinafter, the assembly and the mutual force transmission relationship of the first embodiment configured as described above will be described.

  As shown in FIG. 4, with respect to the first pressure member 25 of the multiple friction member 10, the engagement groove 27 of the first pressure member 25 engages with the engagement protrusion 14 of the first friction member 11. The upper surface of the engaging groove 27 of the engaging and first pressing member 25 is restrained by the locking protrusion 15 of the engaging protrusion 14. The first pressure member 25 is engaged with the second friction member 20 by engaging the pair of guide pieces 29 of the insertion portion 28 on both sides of the second protrusion 22 of the second friction member 20. The second pressure member 30 engages with the second friction member 20 while the first protrusion 21 of the second friction member 20 is inserted between the protruding pieces 31 of the second pressure member 30. .

  Next, the operation of the clutch damper disk assembly having the multiple friction member according to the first embodiment of the present invention having the above-described configuration will be described in detail.

  Since the insertion portion 28 of the first pressure member 25 is disposed horizontally on the upper surface of the second friction member 20, the outer diameter side portion of the first pressure member 25 is in contact with the input side disk member 1, Thereby, almost no deformation occurs, and a sufficient pressure can be applied.

  Since the first pressure member 25 engages with the first friction member 11 in such a manner that the relative rotational movement with the first friction member 11 is limited, the first pressure member 25 and the first pressure member 25 are engaged with each other. There is no friction between the upper surface of the friction member 11 or between the first pressure member 25 and the input side disk member 1. As a result, the frictional action is generated between the flange portion 6 surface of the hub 5 and the first friction member 11, thereby causing a smooth destructive action and canceling the torsional vibration transmitted from the engine. . Therefore, it is possible to reduce the noise generated by the collision of gear teeth generated in the transmission.

  The first protrusion 21 formed on the second friction member 20 has a function of engaging the second friction member 20 and the input side disk member 1, and the second protrusion 22 is the first addition member.

  The present invention does not adopt a structure in which the first friction member 11 is placed on the second friction member 20, and the insertion portion 28 of the first pressure member 25 with which the first friction member 11 is engaged. Since the structure that engages the second protrusion 22 of the second friction member 20 is adopted, it is possible to prevent the first friction member 11 from being disposed away from the second friction member 20.

  Further, since the insertion portion 28 of the first pressure member 25 is engaged and restrained by the second protrusion 22 of the second friction member 20, the assembled multiple friction member 10 is connected to the input side disk member 1. Even when an impact or vibration occurs when the first protrusion 21 of the second friction member 20 is engaged with the groove of the input side disk member 1 in the process of engaging with the first pressure member, Since the movement of 25 is restricted along the second protrusion 22, it can be prevented from being disposed out of the second friction member 20.

  Further, since the first pressure member 25 and the first friction member 11 do not generate friction, the upper surface of the first friction member 11 is worn and the first pressure member 25 and the first friction member 11 are worn. It can prevent that the pressurization force of the 1st pressurization member 25 falls because the clearance gap between the upper surfaces of this becomes large.

(Second Embodiment)
FIG. 13 is a perspective view showing a multiple friction member of a clutch damper disk assembly having multiple friction members according to a second embodiment of the present invention. As shown in FIG. 13, the multiple friction member 10 a includes a first friction member 11 disposed on the flange portion 6 of the hub 5 and a second friction member disposed on the intermediate disk member 7. 20a, a first pressure member 25a that engages with the first friction member 11, and a second pressure member 30a disposed on the second friction member 20a.

  FIG. 14 is a plan view of the second friction member 20a of the clutch damper disk assembly having multiple friction members according to the second embodiment of the present invention, and FIG. 15 is taken along line FF in FIG. It is sectional drawing which shows the cut | disconnected part. As shown in FIGS. 14 and 15, the second friction member 20a is different from the second friction member 20 in that there is no second protrusion 22 and the first protrusion 21 is located in close contact with the inner diameter. That is the point.

  FIG. 16 is a plan view of the first pressure member 25a of the clutch damper disk assembly having multiple friction members according to the second embodiment of the present invention. As shown in FIG. 16, the first pressure member 25a is different from the first pressure member 25 in that the engagement grooves 27a are formed at equal intervals on the circumference of the inner diameter at four locations. It is. For example, four engagement grooves 27 are formed at 90 ° intervals with respect to an inner diameter of about 40 mm.

  FIG. 17 is a plan view of the second pressure member 30a of the clutch damper disk assembly having multiple friction members according to the second embodiment of the present invention. As shown in FIG. 17, the second pressure member 30a differs from the second pressure member 30 in that a plurality of protruding pieces 31a protrude inward on the inner diameter side.

  The assembly and mutual force transmission relationship of the second embodiment configured as described above will be described below.

  As shown in FIG. 13, with respect to the first pressure member 25 a of the multiple friction member 10 a, the engagement groove 27 a of the first pressure member 25 a is engaged with the engagement protrusion 14 of the first friction member 11. . The first pressure member 25a is engaged with the second friction member 20a by engaging the pair of guide pieces 29 of the insertion portion 28 on both sides of the first protrusion 21 of the second friction member 20a. The second pressure member 30a is engaged with the second friction member 20a when the first protrusion 21 of the second friction member 20a is inserted between the protruding piece 31a of the second pressure member 30a. Is done.

  Hereinafter, the operation of the clutch damper disk assembly having the multiple friction member according to the second embodiment of the present invention having the above-described configuration will be described in detail.

  Since the insertion portion 28 of the first pressure member 25a is horizontally disposed on the upper surface of the second friction member 20a, the outer diameter side portion of the first pressure member 25a is in contact with the input side disk member 1. As a result, it is possible to apply a sufficient pressing force with almost no deformation.

  Since the first pressure member 25a engages with the first friction member 11 in a manner that the relative rotational motion with the first friction member 11 is limited, the first pressure member 25a and the first pressure member 25a are engaged with each other. The friction between the upper surface of the friction member 11 and the friction between the first pressure member 25a and the input side disk member 1 does not occur. As a result, the frictional action is generated between the flange portion 6 surface of the hub 5 and the first friction member 11, thereby causing a smooth destructive action and canceling the torsional vibration transmitted from the engine. Therefore, it is possible to reduce the noise generated by the collision of gear teeth generated in the transmission.

  The first protrusion 21 formed on the second friction member 20a functions to engage the second friction member 20a and the input side disk member 1, and the first pressure member 25a and the second pressure member 25a. The friction member 20a is engaged with the friction member 20a so as to rotate together.

  The present invention does not adopt a structure in which the first friction member 11 is placed on the second friction member 20a, and the insertion portion 28 of the first pressure member 25a with which the first friction member 11 is engaged is used. Since the structure that engages with the first protrusion 21 of the second friction member 20a is adopted, it is possible to prevent the first friction member 11 from being disposed away from the second friction member 20a.

  Further, since the insertion portion 28 of the first pressure member 25a is engaged and restrained by the first protrusion 21 of the second friction member 20a, the assembled multiple friction member 10a is connected to the input side disk member 1. When engaging with the first protrusion 21 of the second friction member 20a aligned with the groove of the input side disk member 1 in the process of engaging with the first pressure member, even if an impact or vibration occurs. Since movement of 25a is restrained along the first protrusion 21, it is possible to prevent the 25a from being disposed away from the second friction member 20a.

  Further, since the first pressure member 25a and the first friction member 11 do not generate friction, the upper surface of the first friction member 11 is worn and the first pressure member 25a and the first friction member 11 are worn. A gap between the upper surface of the first pressure member 25a and the first pressure member 25a can be prevented from decreasing.

  Although the preferred embodiments of the present invention have been described above, the present invention can be modified and modified in various ways without departing from the spirit and scope of the present invention. Accordingly, it is intended that the appended claims include such modifications and variations as fall within the spirit of the invention.
