Description

Technical Field

[0001] The present invention relates to a shock absorber device. Background Art

[0002] There is known a shock absorber device that is clamped between a lock-up piston and a turbine hub in a torque converter to reduce torsional vibration in a state where the input side and the output side are directly connected, that is, during lock-up. The shock absorber device is sometimes applied outside the torque converter to other power transmission parts of a vehicle that does not use a torque converter. In the shock absorber device, input-side rotating components such as a retaining plate and output-side rotating components such as an output plate are arranged at the same relative angle and are connected via a spring in the circumferential direction.

[0003] In a state where no torque is input to the input-side rotating component, the spring is in an initial set state and is supported by both the input-side rotating component and the output-side rotating component. At this time, the outer peripheral surface of the end portion of the spring abuts against the end portions of the inner peripheral wall and the outer peripheral wall of the spring housing portion, and the end portion of the spring is positioned in the radial direction of the input-side rotating component. In addition, the inner peripheral surface of the end portion of the spring abuts against both side surfaces of a protrusion portion in the output-side rotating component, and the end portion of the spring is positioned relative to the output-side rotating component (for the above content, refer to Japanese Unexamined Patent Application Publication No. 2005-282651).

[0004] However, when the input-side rotating component and the output-side rotating component are arranged at the same relative angle, if the end portion of the spring does not contact both side surfaces of the input-side rotating component and the output-side rotating component flatly, circumferential play will occur in either the input-side rotating component or the output-side rotating component.

[0005] Specifically, when the end portion of the spring contacts the side surface of the input-side rotating component and separates from the side surface of the output-side rotating component, the input-side rotating component is supported by the spring, but the output-side rotating component is not supported by the spring. As a result, circumferential play occurs in the output-side rotating component. On the contrary, when the end portion of the spring contacts the side surface of the output-side rotating component and separates from the side surface of the input-side rotating component, the output-side rotating component is supported by the spring, but the input-side rotating component is not supported by the spring. As a result, circumferential play occurs in the input-side rotating component.

[0006] If the end portion of the spring can contact both side surfaces of the input-side rotating component and the output-side rotating component flatly, play between the input-side rotating component and the output-side rotating component can be avoided. However, since the input-side rotating component and the output-side rotating component are different components, the centering accuracy of aligning the central axes of the input-side rotating component and the output-side rotating component is low, and it is difficult to make the end portion of the spring contact both the input-side rotating component and the output-side rotating component flatly. Summary of the Invention

[0007] In view of the problems as described above, in the present invention, a shock absorber device is provided that suppresses the shaking of the input-side rotating member and the output-side rotating member.

[0008] The shock absorber device according to the present invention includes an input-side rotating member, an intermediate rotating member, an output-side rotating member, and an elastic body. The input-side rotating member is configured to be rotatable about a rotation axis. The intermediate rotating member is configured to be relatively rotatable independently of the input-side rotating member on the outside of the input-side rotating member about the rotation axis. The output-side rotating member is provided to be relatively rotatable with respect to the intermediate rotating member inside the intermediate rotating member. The elastic body is provided in a circumferential gap between each of a plurality of corresponding portions where the claw portions of the input-side rotating member and the output-side rotating member face each other and the intermediate rotating member. A part of the plurality of corresponding portions is a first corresponding portion configured such that the elastic body is separated from the output-side rotating member and contacts the input-side rotating member. Moreover, the remaining part of the plurality of corresponding portions is a second corresponding portion configured such that the elastic body is separated from the input-side rotating member and contacts the output-side rotating member.

[0009] In the shock absorber device according to the above aspect, the first corresponding portion may be a portion configured such that the elastic body is separated from the output-side rotating member and contacts the input-side rotating member in a stationary state where the rotation of the input-side rotating member has stopped. Moreover, the second corresponding portion may be a portion configured such that the elastic body is separated from the input-side rotating member and contacts the output-side rotating member in the stationary state.

[0010] In the shock absorber device according to the above aspect, the number of the first corresponding portions may be the same as the number of the second corresponding portions.

[0011] In the shock absorber device according to the above aspect, the first corresponding portion and the second corresponding portion may be arranged at equal intervals in the circumference of the shock absorber device.

[0012] In the shock absorber device according to the above aspect, the elastic body may include a first elastic body and a second elastic body. The first elastic body end of the first elastic body is located at a position where, in a rotating state where the input-side rotating member has rotated, the first elastic body main body portion of the first elastic body except for the first elastic body end contacts the output-side rotating member. The second elastic body end of the second elastic body is located at a position where, in the rotating state, the second elastic body main body portion of the second elastic body except for the second elastic body end contacts the input-side rotating member.

[0013] In the shock absorber device of the above-described manner, the shock absorber device can be disposed inside a torque converter having a lock-up clutch, a lock-up piston, a clutch disc, and a turbine hub, and the shock absorber device is configured between any one of the lock-up clutch, the lock-up piston, and the clutch disc and the turbine hub.

[0014] According to the shock absorber device of the present invention, it is possible to suppress the swaying of the input-side rotating member and the output-side rotating member. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Hereinafter, with reference to the drawings, the manner for implementing the present invention will be described.

[0024] As Figure 1As shown, the shock absorber device 1 is disposed inside the torque converter 2. The shock absorber device 1 is provided in the torque transmission path between the internal combustion engine 3 and the transmission 4. The internal combustion engine 3 can be a gasoline engine or a diesel engine. The transmission 4 can be a stepped transmission with a stepped change in the transmission ratio or a continuously variable transmission with a continuously variable transmission ratio. The shock absorber device 1 reduces the vibration of the torque generated by the internal combustion engine 3 and transmits it to the transmission 4.

[0025] The torque converter 2 includes a housing 5. Oil for torque transmission is sealed inside the housing 5. The housing 5 includes a front cover 6 and a pump housing 7. The front cover 6 is connected to the output shaft 3a of the internal combustion engine 3. The pump housing 7 is integrally provided on the front cover 6. The torque converter 2 becomes a liquid-tight state through the front cover 6 and the pump housing 7.

[0026] A plurality of pump vanes 8 are installed on the pump housing 7. By installing a plurality of pump vanes 8 on the pump housing 7, a pump impeller 9 is formed. A turbine runner 10 is arranged opposite to the pump impeller 9. The turbine runner 10 rotates by receiving the oil flow generated by the pump impeller 9. The turbine runner 10 has a shape symmetrical to the pump impeller 9. The turbine runner 10 includes a turbine housing (not shown) and a large number of turbine blades 11 installed on the inner surface of the turbine housing. The turbine runner 10 is connected to the input shaft 4a of the transmission 4 via a turbine hub 12.

[0027] A stator 13 is arranged between the pump impeller 9 and the turbine runner 10. The stator 13 is installed on a fixed shaft (not shown) inside the torque converter 2 via a one-way clutch 14. In a state where the speed ratio between the pump impeller 9 and the turbine runner 10 is small, the stator 13 changes the flow direction of the oil flowing out from the turbine runner 10. On the other hand, in a state where the speed ratio is large, the stator 13 is rotated by being pressed by the oil flowing out from the turbine runner 10, and thus the flow direction of the oil is not changed. Therefore, the one-way clutch 14 engages and stops the rotation of the stator 13 in a state where the speed ratio is small, and rotates the stator 13 in a state where the speed ratio is large.

[0028] A lock-up clutch 15 is arranged inside the front cover 6 opposite to the inner surface of the front cover 6. The lock-up clutch 15 includes a plurality of clutch discs 16 and a plurality of clutch plates 18. That is, the lock-up clutch 15 is a multi-disc clutch. The clutch discs 16 are spline-fitted to a clutch hub integrated with the front cover 6. The clutch plates 18 are alternately arranged with the clutch discs 16. The clutch plates 18 are spline-fitted to the inner peripheral surface of a clutch drum 17 arranged to cover the outer peripheral side of the clutch hub.

[0029] The clutch driven plate 16 and the clutch plate 18 are alternately arranged between a locking piston (not shown) and a snap ring (not shown) mounted on the clutch drum 17. When the locking piston advances, the clutch driven plate 16 and the clutch plate 18 are clamped between the locking piston and the snap ring, so that the clutch driven plate 16 and the clutch plate 18 are in frictional contact with each other and torque is transmitted between them. That is, the lock-up clutch 15 becomes an engaged state for torque transmission.

[0030] In addition, although not shown, in the radial direction of the torque converter 2, a return spring is arranged in parallel with at least a part of the inner peripheral side of the lock-up clutch 15. The return spring presses the locking piston in the direction of releasing the lock-up clutch 15, that is, in the direction of separating the clutch driven plate 16 and the clutch plate 18. As described above, the torque converter 2 includes a lock-up clutch 15, a locking piston, a clutch driven plate 16, and a turbine hub 12.

[0031] The shock absorber device 1 is arranged between at least any one of the lock-up clutch 15, the locking piston, and the clutch driven plate 16 and the turbine hub 12. The shock absorber device 1 is arranged adjacent to the lock-up clutch 15 in the axial direction of the rotation center axis (hereinafter, simply referred to as the rotation axis) of the torque converter 2. A disc-shaped or ring-shaped piston plate 21 is connected to the clutch drum 17 of the lock-up clutch 15. A ring-shaped retaining plate 22 is connected and fixed to the piston plate 21 by rivets 23. The retaining plate 22 is an example of an input-side rotating member and can rotate around the rotation axis. Bolts can be used instead of the rivets 23. The piston plate 21 is located on the side closer to the lock-up clutch 15 than the retaining plate 22 in the axial direction of the rotation axis.

[0032] The piston plate 21 and the retaining plate 22 are arranged at a predetermined interval in the axial direction of the rotation axis. Since the piston plate 21 and the retaining plate 22 are connected, they rotate integrally while maintaining this interval. In this way, the piston plate 21 and the retaining plate 22 are arranged on the upstream side in the torque transmission direction. A ring-shaped intermediate plate 27 independent of the retaining plate 22 is provided on the outer peripheral portion of the retaining plate 22. The intermediate plate 27 is an example of an intermediate rotating member and can rotate independently relative to the retaining plate 22 outside the retaining plate 22 around the rotation axis.

[0033] An output plate 26 is arranged on the downstream side in the torque transmission direction of the piston plate 21 and the retaining plate 22 in the axial direction of the rotation axis. The output plate 26 is an example of an output-side rotating member and can rotate relative to the intermediate plate 27 inside the intermediate plate 27. The output plate 26 is connected to the intermediate plate 27 via a torsion spring 28 as an elastic body so as to be able to rotate relative to the retaining plate 22 and the intermediate plate 27 at a predetermined angle.

[0034] More specifically, as Figure 2As shown, the intermediate plate 27 surrounds the outer peripheries of the holding plate 22 and the output plate 26. A plurality of torsion springs 28 are circumferentially arranged inside the intermediate plate 27. The intermediate plate 27 elastically connects the holding plate 22 and the output plate 26 in the rotational direction through the plurality of torsion springs 28. The plurality of torsion springs 28 include a first torsion spring S1, a second torsion spring S2, a third torsion spring S3, a fourth torsion spring S4, etc. The first torsion spring S1 is an example of a first elastic body, and the second torsion spring S2 is an example of a second elastic body. The intermediate plate 27 causes the plurality of torsion springs 28 to work in series. The intermediate plate 27 can slide and relatively rotate independently of the rotational movements of the holding plate 22 and the output plate 26.

[0035] On the inner periphery of the intermediate plate 27, four inner peripheral protrusions including inner peripheral protrusion portions 27P and 27Q are provided at approximately 90-degree intervals from the rotation axis O. On both circumferential side surfaces of the inner peripheral protrusions, that is, the spring contact portions 27R, one end of the torsion spring 28 is supported. The inner peripheral side edge portion of the intermediate plate 27 other than the inner peripheral protrusions has an inner peripheral flange portion 27S.

[0036] On the outer periphery of the holding plate 22, four outer peripheral protrusions 22A, 22B, 22C, and 22D are provided as claw portions at approximately 90-degree intervals from the rotation axis O. For example, the outer peripheral protrusion 22A is arranged at a 45-degree interval with respect to the inner peripheral protrusion 27P. The remaining outer peripheral protrusions 22B, 22C, and 22D are also arranged at a 45-degree interval with respect to the inner peripheral protrusion. On both circumferential side surfaces of the outer peripheral protrusions 22A and 22C, that is, the outer peripheral spring contact portions 22E, the other end of the torsion spring 28 is supported. On both circumferential side surfaces of the outer peripheral protrusions 22B and 22D, that is, the outer peripheral spring contact portions 22F, the other end of the torsion spring 28 is separated from the outer peripheral protrusions 22B and 22D.

[0037] Each front end portion of the outer peripheral protrusions 22A, 22B, 22C, and 22D of the holding plate 22 has two-stage claws, a front upper claw and a front lower claw (also refer to Figure 4A and Figure 4B ). The outer peripheral protrusions 22A, 22B, 22C, and 22D are respectively located on the opposite sides with respect to the piston plate 21 (refer to Figure 1 ), and the inner peripheral flange portion 27S of the intermediate plate 27 is held slidably by the front upper claw and the front lower claw. The inner peripheral surface of the intermediate plate 27 other than the inner peripheral flange portion 27S supports the outer side surface of the torsion spring 28.

[0038] On the outer periphery of the output plate 26, four outer peripheral claws 26A, 26B, 26C, and 26D are provided as claws at intervals of approximately 90 degrees from the rotation axis O. The four outer peripheral claws 26A, 26B, 26C, and 26D are provided corresponding to the four outer peripheral protrusions 22A, 22B, 22C, and 22D of the retaining plate 22, respectively. That is, the four outer peripheral claws 26A, 26B, 26C, and 26D are provided at the same relative angle as the four outer peripheral protrusions 22A, 22B, 22C, and 22D, and their relative angles are consistent. A torsion spring 28 is provided in the circumferential gap between each corresponding portion 1A, 1B, 1C, and 1D where the four outer peripheral claws 26A, 26B, 26C, and 26D and the four outer peripheral protrusions 22A, 22B, 22C, and 22D are respectively opposed and each inner peripheral protrusion of the intermediate plate 27. For example, a first torsion spring S1 is provided in a gap in the circumferential direction between the corresponding portion 1A and the inner peripheral protrusion 27P, and a second torsion spring S2 is provided in a gap in the circumferential direction between the corresponding portion 1A and the inner peripheral protrusion 27Q.

[0039] In the first corresponding parts 1A and 1C, which are part of the corresponding parts 1A, 1B, 1C and 1D, the torsion spring 28 is separated from the outer peripheral claws 26A and 26C of the output plate 26 and is in contact with the outer peripheral protrusions 22A and 22C of the holding plate 22. For example, in the first corresponding part 1A, the other end of the first torsion spring S1 and the other end of the second torsion spring S2 are separated from the outer peripheral claw 26A and are in contact with the outer peripheral protrusion 22A of the holding plate 22. In this way, in the first corresponding part 1A, even if the circumferential side surfaces of the outer peripheral protrusion 22A and the outer peripheral claw 26A are not flat, the holding plate 22 can be sandwiched by the first torsion spring S1 and the second torsion spring S2 in contact with the outer peripheral protrusion 22A. The first corresponding part 1C is also the same as the first corresponding part 1A. In this way, since the outer peripheral protrusions 22A and 22C are respectively supported by the two torsion springs 28 , it is possible to suppress the circumferential play of the holding plate 22 .

[0040] On the other hand, in the second corresponding portions 1B and 1D, which are the remaining portions of the above corresponding portions 1A, 1B, 1C, and 1D, the torsion springs 28 are separated from the outer peripheral protrusions 22B and 22D of the holding plate 22 and come into contact with the outer peripheral claws 26B and 26D of the output plate 26. For example, in the second corresponding portion 1B, the other ends of the ends of the third torsion spring S3 and the other ends of the ends of the fourth torsion spring S4 are both separated from the outer peripheral protrusion 22B of the holding plate 22 and come into contact with the outer peripheral claw 26B of the output plate 26. Thus, in the second corresponding portion 1B, even if the circumferential sides of the outer peripheral protrusion 22B and the outer peripheral claw 26B are not flat surfaces, the output plate 26 can be clamped by the third torsion spring S3 and the fourth torsion spring S4 that are in contact with the outer peripheral claw 26B. The same applies to the second corresponding portion 1D. Thus, by supporting the outer peripheral claws 26B and 26D by two torsion springs 28 respectively, the circumferential wobbling of the output plate 26 can also be suppressed.

[0041] That is, even if the circumferential sides of the outer peripheral protrusion 22A and the outer peripheral claw 26A, the circumferential sides of the outer peripheral protrusion 22B and the outer peripheral claw 26B, etc. are not flat surfaces, the circumferential wobbling of both the holding plate 22 and the output plate 26 can be suppressed. The same applies to the remaining outer peripheral protrusions 22C, 22D and outer peripheral claws 26C, 26D.

[0042] When no torque is input to the piston plate 21 and the holding plate 22 is in a stationary state of rotational rest as shown in Figure 2 and Figure 3A if torque is input to the piston plate 21, then as shown in Figure 3B it moves to a rotational state in which the holding plate 22 rotates. When it moves to the rotational state, the outer peripheral protrusion 22A of the holding plate 22 moves circumferentially as shown by the arrow R. Thereby, the outer peripheral protrusion 22A presses the second torsion spring S2. In addition, as the outer peripheral protrusion 22A moves, the other end of the end of the first torsion spring S1 that is in contact with the outer peripheral protrusion 22A comes into contact with the outer peripheral claw 26A. Among them, in Figure 3A and Figure 3B for the sake of easy understanding of this operation, the detailed illustrations of the first torsion spring S1 and the second torsion spring S2 are omitted.

[0043] Here, the winding end and the ground end of the first torsion spring S1 according to the present embodiment are located at positions where the spring body portion of the first torsion spring S1 except for the winding end and the ground end comes into contact with the outer peripheral claw 26A of the output plate 26 in the above rotational state. The ground end according to the present embodiment is a surface obtained by grinding the end face of the torsion spring 28 into a plane perpendicular to the axis.

[0044] Specifically, as shown by the arrow ⅣA in Figure 3B when the outer peripheral claw 26A is observed from the side, as shown in Figure 4AAs shown, the outer peripheral claws 26A of the output plate 26 are bent in the direction of the outer peripheral protrusion 22A. The winding end E1 and the grinding end E2 of the first torsion spring S1 are located at the first specified position, and this first specified position enables the spring body portion Sb of the first torsion spring S1 to contact the claw edge 26N at the front end of the bent outer peripheral claw 26A. Thus, even when moved to the rotating state, as shown by the dashed circle C1, the spring body portion Sb stably contacts the claw edge 26N, and compared with the case where the winding end E1 and the grinding end E2 are not located at the first specified position, the positions of the holding plate 22 and the output plate 26 can be stabilized. Here, the spring body portion Sb of the first torsion spring S1 is an example of the first elastic body main portion, and the winding end E1 and the grinding end E2 are examples of the first elastic body ends.

[0045] In addition, the winding end and the grinding end of the second torsion spring S2 according to the present embodiment are also located at positions that enable the spring body portion of the second torsion spring S2 to contact the outer peripheral protrusion 22A of the holding plate 22 in the above rotating state.

[0046] Specifically, as Figure 3B shown by the arrow IVB, when the outer peripheral protrusion 22A is viewed from the side, as Figure 4B shown, a part of the outer peripheral protrusion 22A of the holding plate 22 is bent in a U shape. The winding end E3 and the grinding end E4 of the second torsion spring S2 are located at the second specified position, and this second specified position enables the spring body portion Sb of the second torsion spring S2 to contact the U-shaped piece 22N of the outer peripheral protrusion 22A that is closer to the rotation axis side than the claw edge 26N. Thus, even when moved to the rotating state, as shown by the dashed circles C2 and C3, the spring body portion Sb stably contacts the U-shaped piece 22N, and compared with the case where the winding end E3 and the grinding end E4 are not located at the second specified position, the positions of the holding plate 22 and the output plate 26 can be stabilized. Here, the spring body portion Sb of the second torsion spring S2 is an example of the second elastic body main portion, and the winding end E3 and the grinding end E4 are examples of the second elastic body ends.

[0047] For example, as Figure 5 shown in the comparative example, when the winding end E1 and the grinding end E2 are not located at the first specified position and the winding end E3 and the grinding end E4 are not located at the second specified position, the positions of the holding plate 22 and the output plate 26 are unstable according to the number of measurements, and the imbalance (rotational balance) phase of the holding plate 22 and the output plate 26 changes.

[0048] However, as Figure 5As shown in the embodiment, when the winding end E1 and the grinding end E2 are located at the first specified position and the winding end E3 and the grinding end E4 are located at the second specified position, regardless of the number of measurements, the positions of the holding plate 22 and the output plate 26 are stable, and it is only necessary that the imbalance (rotational balance) phase between the holding plate 22 and the output plate 26 does not change.

[0049] The preferred embodiments of the present invention have been described in detail above, but the present invention is not limited to the above specific embodiments, and various modifications and changes can be made without departing from the gist of the present invention described in the technical solution.

[0050] For example, in the above embodiment, two first corresponding portions 1A, 1C and two second corresponding portions 1B, 1D are described, but six outer peripheral claws and six outer peripheral protrusion portions may also be provided in association. In this case, the outer peripheral claws and the outer peripheral protrusion portions can be arranged at intervals of 60 degrees, and the number of the first corresponding portions and the second corresponding portions can be three each. In addition, in the above embodiment, the shock absorber device 1 is provided inside the torque converter 2, but for example, the shock absorber device 1 can also be provided outside the torque converter 2 or in other power transmission parts of a vehicle that does not use the torque converter 2.
