  In a multi-plate clutch as described in Patent Document 1, in order to ensure a predetermined torque capacity, it is necessary to include a plurality of friction engagement plates and engagement hydraulic mechanisms. As it increases, there is a problem that drag torque increases between the friction engagement plates at the time of non-engagement. In order to reduce such drag torque, a contrivance has been made such that the shape of the friction engagement plate is changed to a wave shape, but a sufficient effect has not been obtained. Moreover, in order to maintain the engagement state of the friction engagement plate, it is necessary to always apply hydraulic pressure, and there is a problem that it is necessary to provide a pressurizing mechanism for that purpose.

  In the dog clutch as described in Patent Document 2, since the rotational drive is transmitted by the engagement between the dog tooth and the dog tooth engaging portion, the drag torque as described above is not generated. There is a problem that it is necessary to secure a space for moving the engaging portion in the rotation axis direction, and it is difficult to downsize the apparatus in the axial direction. Further, when the dog teeth and the dog tooth engaging portion are engaged, it is difficult to absorb the rotation difference between the two, and there is a problem that damage and impact sound are unavoidable when engaged.

  Therefore, the present invention has a function of reducing drag torque and can reduce the rotation difference during engagement to smoothly realize the engaged state and prevent the apparatus from being enlarged in the direction of the rotation center axis. An object of the present invention is to provide a transmission device for rotational drive that can be used.

And an engaging portion that transmits rotational power from the input side member to the output side member by setting the engaging operation member and the engaging member in an engaged state. Furthermore, the operation part includes a position setting mechanism that rotates the engagement operation member to set the operation position or the release position. Further, the position setting mechanism includes a rotating member that reciprocally rotates in the circumferential direction by hydraulic pressure, and the engagement operating member is moved to the operating position or the release in conjunction with the reciprocating rotating operation of the rotating member. Set to position. The rotary friction clutch further includes a friction plate connected to one of the input side and the output side and a friction disk connected to the other, and the input side member and the output are brought into contact with the friction plate and the friction disk. The rotational difference between the side members is reduced. Furthermore, the engagement operation member includes a pressing portion that presses the friction plate and the friction disk so as to be in contact with each other, and a locking portion that engages with the engagement member in conjunction with a pressing operation of the pressing portion. And. Further, the rotary friction clutch includes the friction plates arranged alternately and an operation plate that is set to move in a direction to bring the friction plates into a contact state and has a tapered operation surface. The operating portion is set such that when the engagement operating member is set to the operating position, the pressing portion contacts the operating surface to move the operating plate.

  The clutch device according to the present invention is set so as to be interlocked with one of the input side member or the output side member, and is interlocked with the other of the input side member or the output side member, and the operating portion having the engagement operating member. The input side member by setting the engagement operating member and the engagement member in an engagement state that rotates about a rotation center axis. In the clutch device that transmits the rotational power of the output side member to the output side member, the engagement actuating member is notched to a position including the rotation axis in a direction orthogonal to the rotation axis along the rotation center axis and extends along the rotation center axis An engaging portion having an engaging surface is provided as described above, and the engaging member is provided with an engaging protrusion that protrudes in the radial direction of the rotation center shaft.

  The present invention has the above-described configuration, and reduces the rotational difference between the input side member and the output side member by operating the rotary friction clutch by the engagement operating member while having the function of reducing the drag torque. At the same time, the engagement actuating member is engaged with the engagement member to transmit power from the input side member to the output side member, so that the engagement state is smoothly set in a state where the rotation difference is reduced. It becomes possible.

  In addition, since the engagement actuating member is rotated and set in the engaged state with the engagement member, the stroke length can be shortened, the space in the rotation center axis direction can be reduced, and the rotation center The size of the apparatus can be reduced by avoiding an increase in the size of the apparatus in the axial direction.

  Hereinafter, embodiments according to the present invention will be described in detail. The embodiments described below are preferable specific examples for carrying out the present invention, and thus various technical limitations are made. However, the present invention is particularly limited in the following description. Unless otherwise specified, the present invention is not limited to these forms.

  FIG. 1 is an external perspective view of an embodiment of the present invention, and FIG. 2 is a cross-sectional view in a direction along the rotation center axis. In FIG. 2, since the same cross section appears symmetrically around the rotation center axis, only one cross section is shown. In this example, a clutch device will be described as an example of a rotational drive transmission device. The clutch device includes a plurality of rotating members that are rotatably mounted about a rotation center axis T. In the following description, the direction along the rotation center axis T is referred to as “axial direction”, the direction orthogonal to the rotation center axis T is referred to as “radial direction”, and the circumferential direction around the rotation center axis T is referred to as “circumferential direction”. explain.

  The clutch device 1 is configured to transmit or disconnect power between the sleeve 2 and the hub 3, one being an input side member for rotational power and the other being an output side member. The sleeve 2 is formed in a disc shape, and has a central portion opened and a cylindrical portion 2a extending in the axial direction. The hub 3 is formed in a cylindrical shape, and a shaft member corresponding to the rotation center axis T is inserted into the center portion. A cylindrical portion 2 a of the sleeve 2 is attached to the outer peripheral surface of one end portion of the hub 3, and the sleeve 2 is rotatably attached around the hub 3.

  The clutch device 1 is related to a rotational friction clutch 10 that is a rotational operation unit that reduces a rotational difference between the sleeve 2 and the hub 3, an operating position where the rotational friction clutch 10 is in an operating state, or a release position where the operating state is released. Power is transmitted between the sleeve 2 and the hub 3 by setting the actuating portion 20 for setting the combined actuating member 21 and the engaging actuating member 21 and the engaging member 31 in the actuated state to be in the engaged state. And an engaging portion 30.

  The rotational friction clutch 10 follows the rotational operation of the input side member that rotates when the rotational power is transmitted, and rotates the output side member to reduce the rotational difference so that the rotational operation between them is synchronized. In this example, the rotary friction clutch 10 includes a plurality of friction plates 11 and a friction disk 12 that are used in a known wet multi-plate clutch.

  The friction plate 11 is attached to a drum member 13 fixed to the other side edge with respect to the ring-shaped cover 4 having one side edge fixed to the outer peripheral edge of the sleeve 2. The outer peripheral edge of the sleeve 2 and the outer peripheral edge of the drum member 13 are overlapped on both side edges of the cover 4, bolts are inserted, and nuts are screwed onto the bolts to fasten and fix each member. The cover 4 and the sleeve 2 are integrally rotated about the rotation center axis T. A plurality of engagement grooves 13a are formed on the inner peripheral surface of the drum member 13, and a plurality of engagement protrusions formed on the outer peripheral portion of the friction plate 11 are fitted into the plurality of engagement grooves 13a to form splines. By being engaged, the friction plate 11 is regulated and attached so as to be movable in the axial direction and not to move in the circumferential direction.

  The friction disk 12 is attached to a hub member 14 that is fastened and fixed by bolts and nuts to an engaging portion 30 that extends in the radial direction from the hub 3, and the hub 3 and the hub member 14 have a center of rotation. The shaft T is integrally rotated around the axis T. A plurality of engagement protrusions 14a are formed on the outer peripheral surface of the hub member 14, and a plurality of engagement grooves formed on the inner peripheral portion of the friction disk 12 are fitted to the plurality of engagement protrusions 14a to form splines. By being engaged, the friction disk 12 is regulated and attached so as to be movable in the axial direction but not in the circumferential direction.

  The friction plates 11 and the friction disks 12 are alternately arranged. A friction plate 15 formed thicker than the friction plate 11 is disposed on the opposite side of the sleeve 2, and the friction plate 11 is thicker than the friction plate 11 on the sleeve 2 side. The formed actuating plate 17 is arranged. The friction plate 15 and the operation plate 17 are spline-engaged with the drum member 13 in the same manner as the friction plate 11, and are attached so as to be movable in the axial direction and not to move in the circumferential direction.

  A stopper 16 is provided on the friction plate 15 to prevent the friction plate 15 from coming off in the axial direction. On the inner peripheral side of the working plate 17, a working surface 17 a that is notched and formed in a tapered shape is formed on the sleeve 2 side, and the working surface 17 a is an engagement working member 21 described later. Is disposed opposite to the shaft portion 21a formed at the tip of the shaft.

  Since the rotary friction clutch 10 is configured as described above, when the operating surface 17a is pressed by the shaft portion 21a so as to be displaced in the axial direction, the operating plate 17 moves in the axial direction and the friction plate 11 and The friction disk 12 comes into contact. The friction plate 11 is connected to the sleeve 2 so as to be regulated in the circumferential direction, and the friction disk 12 is connected to the hub 3 so as to be regulated in the circumferential direction. The contact of the disk 12 causes the sleeve 2 and the hub 3 to follow one rotational operation that transmits rotational power and the other to rotate, so that the rotational difference between the two is reduced.

  In this case, it is not necessary to bring the friction plate 11 and the friction disk 12 into close contact so that the sleeve 2 and the hub 3 rotate in synchronism, and when an engagement member 31 and an engagement actuating member 21 described later are engaged. It is sufficient that the rotational difference between the two is reduced to such an extent that no impact is generated. Therefore, the number of the friction plates 11 and the friction disks 12 may be small, and the pressing force against the operation plate 17 can be reduced. Therefore, it is possible to ensure the space between the friction plate 11 and the friction disk 12 and reliably prevent the generation of drag torque. Note that hydraulic oil or the like can be interposed between the friction plate 11 and the friction disk 12 as necessary.

  The operating portion 20 rotates the engagement operating member 21 to operate the operating plate 17 and engages with the engaging member 31 of the engaging portion 30. The engagement actuating members 21 are arranged at a plurality of positions on the outer peripheral portion of the sleeve 2 at equal intervals, and are rotatably supported between the outer peripheral portion of the sleeve 2 and the inner peripheral edge portion of the cover 4. It rotates around a rotation axis along T. The engagement actuating member 21 includes a pinion gear portion 21 b having a gear train formed in the axial direction on a cylindrical outer peripheral surface between the sleeve 2 and the cover 4, and is supported by the cover 4. A shaft portion 21 a is provided so as to project from the portion toward the operation plate 17.

  FIG. 3 is a partially enlarged perspective view of the shaft portion 21a. The shaft portion 21a is formed in a columnar shape, and a locking portion 21c is formed along the axial direction by notching a portion facing the engaging member 31 at the tip portion. The locking portion 21c is formed by cutting out to a position including the rotation axis in a direction orthogonal to the rotation axis of the shaft portion 21a. At the tip of the locking part 21c, a pressing part 21d protruding in the axial direction by cutting out a portion facing the operating plate 17 is formed, and the tip surface of the pressing part 21d is a narrow pressing surface, and the pressing surface is The operating plate 17 is set to face the operating surface 17a. Therefore, in FIG. 3, the distal end portion of the shaft portion 21 a and the locking portion 21 c are set at a release position where the operation plate 17 and the engaging member 31 are not contacted.

  In this example, as a position setting mechanism that operates by rotating the engagement operation member 21 to the operation position or the release position, the engagement operation member 21 is operated in conjunction with a rotation member that reciprocally rotates in the circumferential direction by hydraulic pressure. It has a mechanism. The position setting mechanism is a hydraulic chamber forming member 22 fitted around the cylindrical portion 2a of the sleeve 2 and a rotating member that is disposed on the outer peripheral side of the hydraulic chamber forming member 22 and is rotatably attached in the circumferential direction. A sun gear member 23 is provided. The hydraulic chamber forming member 22 and the sun gear member 23 are provided with the sleeve 2 and the regulating member 24 in close contact with each other on both sides in the axial direction so that the hydraulic oil supplied to the hydraulic chamber does not leak as will be described later. It has become. The oil pressure forming member 22 is attached so as to rotate together with the sleeve 2, and the sun gear member 23 is rotatable between the sleeve 2 and the regulating member 24 in the circumferential direction with respect to the oil pressure chamber forming member 22. It is attached so as not to move in the direction.

  FIG. 4 is a view of the hydraulic chamber forming member 22 and the sun gear member 23 as seen from the axial direction. The hydraulic chamber forming member 22 includes an annular shaft support portion 22a and four support portions 22b extending in the radial direction from the outer peripheral side of the shaft support portion 22a, and the support portions 22b are arranged at equal intervals. A gap is formed in each. The sun gear member 23 includes an annular gear portion 23a having a tooth row formed on the outer peripheral portion, and a partition portion 23b extending in the radial direction from the inner peripheral side of the gear portion 23a. The chamber forming members 22 are disposed between the support portions 22b.

  The outer peripheral side end surface of the support portion 22b is in contact with the inner peripheral surface of the gear portion 23a and is liquid-tightly adhered to both sides in the circumferential direction by the circumscribed seal member 22e, and the inner peripheral side end surface of the partition portion 23b is the outer periphery of the shaft support portion 22a. It is in contact with the surface and in close contact with the inner seal member 23c. Therefore, hydraulic chambers are respectively formed between the support portion 22b and the partition portion 23b in the circumferential direction, and the inlet 22c that introduces hydraulic oil into the hydraulic chamber on one side of the partition portion 23b is provided in the shaft support portion 22a. An inlet 22d for introducing hydraulic oil into the hydraulic chamber on the other side is formed. The inlets 22c and 22d communicate with supply passages 2b and 2c formed inside the cylindrical portion 2a of the sleeve 2, respectively, from an external hydraulic oil supply mechanism (not shown) to the hydraulic chamber via the supply passage. Supply operations such as introduction and discharge of hydraulic oil are performed.

  In FIG. 4, hydraulic fluid is introduced into the hydraulic chamber on one side of the partition portion 23b from the introduction port 22c and discharged from the hydraulic chamber on the other side, so that the partition portion 23b is moved to the hydraulic chamber on the other side. It is turning toward. In FIG. 5, hydraulic oil is introduced from the inlet 22d into the hydraulic chamber on the other side of the partition 23b and discharged from the hydraulic chamber on one side, so that the partition 23b is moved to the hydraulic chamber on one side. It is turning toward. Abutting portions projecting in the circumferential direction are formed on both side surfaces of the partition portion 23b in the circumferential direction, and the abutment portions abut on the side surfaces of the support portion 22b, so that the partition portion 23b is within a predetermined range. Will turn.

  Thus, by rotating the partition portion 23b in the circumferential direction, the sun gear member 23 is rotated in the circumferential direction, and the pinion gear portion 21b of the engagement operating member 21 that meshes with the sun gear member 23 is rotated. become. In the state shown in FIG. 4, the locking portion 21 c of the engagement actuating member 21 is set at a release position where it is not engaged with the engagement member 31. In the state shown in FIG. 5, the engagement actuating member 21 is rotated by the rotation. The stopping portion 21c is set to an operating position that engages with the engaging member 31 from the release position.

  In the example described above, the sun gear member 23 is rotated by introducing hydraulic oil into the hydraulic chambers on both sides in the circumferential direction of the partition portion 23 b, and the engagement operating member 21 is rotated by the rotation of the sun gear member 23 to be released. The position and the operating position are set, but an elastic member such as a spring is built in one hydraulic chamber, the hydraulic oil is introduced into the other hydraulic chamber, and the hydraulic oil is discharged from the other hydraulic chamber. The sun gear member 23 can also be rotated by the repulsive force of the elastic member.

  In addition, a drive mechanism such as a motor that rotates the engagement operation member 21 may be attached to the sleeve 2 so that the engagement operation member 21 is electrically rotated. Any other rotation method can be adopted as long as it can be rotated, and is not particularly limited.

  As shown in FIG. 2, the engaging portion 30 includes a disk-like engaging member 31 extending in the radial direction from the hub 3, and a plurality of engaging protrusions are formed on the outer peripheral portion of the engaging member 31. 31a is projected in the radial direction. FIG. 6 is a view of the engaging portion 30 as viewed from the axial direction. Engaging members 31 extending radially on the outer peripheral side of the hub 3 are provided with engaging protrusions 31a at equal intervals on the outer peripheral portion. In the state shown in FIG. 6, the engagement operation member 21 is set to the release position, and the locking portion 21c of the engagement operation member 21 is not in contact with the engagement protrusion 31a. In the state shown in FIG. 7, as shown in FIG. 5, the engagement actuating member 21 is rotated and set to the actuated position, and is engaged with the engagement protrusion 31a by the rotation of the locking portion 21c. Yes.

  8 to 10 are explanatory views showing the operation process of the operating unit 20. In each figure, FIG. (A) is an axial sectional view similar to FIG. 2, and FIG. (B) is an explanatory view of the operating state of the shaft portion 21a viewed from the axial direction. In the figure, the rotation axis S of the engagement actuating member 21 (shaft portion 21a) is shown, and the pressing surface of the pressing portion 21d is indicated by hatching.

  In FIG. 8, the engagement operation member 21 is set to the release position, and the pressing portion 21 d formed at the tip portion of the shaft portion 21 a is the operation surface formed on the sleeve 2 side on the inner peripheral side of the operation plate 17. Opposed to 17a. The working surface 17a is formed so as to taper toward the inner peripheral side with a predetermined thickness in the radial direction and reduced in thickness over the entire periphery. It is set so that the interval between the two terminals 21d increases. Therefore, in the state where the engagement operation member 21 is set to the release position, the pressing portion 21d is set so that the longitudinal direction thereof is along the circumferential direction, and the tip of the pressing surface 21a is formed on the thin portion on the inner peripheral side of the operation surface 17a. The pressing surfaces are arranged opposite to each other so that there is an interval so as not to contact each other. In addition, since the engaging surface of the locking portion 21 c is also set along the circumferential direction, the locking portion 21 c is set so as not to contact the engaging protrusion 31 a of the engaging member 31.

  In the example shown in FIG. 8, the engagement member 31 rotates clockwise as indicated by an arrow. However, when the engagement operation member 21 is set at the release position, the operation surface 17a of the operation plate 17 is engaged. It is not pressed in the axial direction by the pressing portion 21d of the combined operation member 21. Therefore, the rotary friction clutch 10 is not operating, and the locking portion 21c is not engaged with the engagement protrusion 31a, so that the input side (hub 3 interlocked with the engagement member 31) and the output side (engagement operation) The sleeve 2) interlocked with the member 21 is in a disconnected state, and no rotational power is transmitted from the input side to the output side.

  FIG. 9 shows a state in which the engagement operation member 21 has started rotating due to the operation start of the operation unit 20. By starting the rotation of the engagement actuating member 21, the pressing portion 21d at the tip of the shaft portion 21a is rotated, and the pressing portion 21d is inclined with respect to the circumferential direction. Therefore, in the pressing portion 21d, one end portion side in the circumferential direction rotates toward the outer peripheral side to move the operating surface 17a, and accordingly, the inner peripheral side from the inner peripheral side where the thickness of the operating surface 17a is thin is changed to the outer peripheral side. The operation plate 17 is pressed so as to gradually move in the axial direction while coming into contact with the tapered slope. On the other hand, at the stage where the pressing portion 21d starts to be inclined with respect to the circumferential direction, the other end portion side rotates toward the inner peripheral side, but it is avoided that it contacts the tip of the engaging protrusion 31a. Since it is set, it is not in the engaged state between the engaging protrusion 31a and the locking portion 21c. Therefore, the rotary friction clutch 10 is operated by the pressing operation by the pressing portion 21d against the operating plate 17, so that the sleeve 2 and the hub 3 start the rotating operation in conjunction with each other, and the rotational difference therebetween is reduced. Although the rotation operation is started, the engagement protrusion 31a and the locking portion 21c are not engaged, and the sleeve 2 and the hub 3 start a smooth rotation operation via the rotating friction clutch 10. Is done.

  As shown in FIG. 9, since the hub 3 on the input side and the sleeve 2 on the output side start to rotate in synchronization with the operation of the rotary friction clutch 10, the pressing of the engagement operating member 21 interlocked with the sleeve 2 The portion 21d starts rotating operation in synchronization with the engaging member 31 as indicated by the arrow, and the rotational difference between the two portions is reduced.

  FIG. 10 shows a state in which the engagement operation member 21 is rotated and set to the operation position. When the engagement actuating member 21 further rotates from the state shown in FIG. 9, the pressing portion 21 d is in a state where the inclination angle with respect to the circumferential direction is increased and the actuating plate 17 is pressed, and the locking portion 21 c is the engaging protrusion. It will be in contact with the corner | angular part of 31a. Therefore, the sleeve 2 and the hub 3 are rotated at the same rotational speed in conjunction with the circumferential direction via the engagement actuating member 21 and the engagement member 31 while the rotational difference is further reduced by the rotational friction clutch 10. . When the engagement operation member 21 is set to the operation position, the engagement surface of the locking portion 21c is in close contact with the circumferential end surface of the engagement protrusion 31a, and the engagement state is set. 2 and the hub 3 are in a state in which the rotational power is stably transmitted by the engagement of the engagement actuating member 21 and the engagement member 31. Since the locking portion 21c is formed by cutting out to a position including the rotation axis S in a direction orthogonal to the rotation axis S of the engagement operating member 21, the rotation axis S is closer to the engagement protrusion 31a than the engagement surface. Therefore, the engagement actuating member 21 is prevented from being inadvertently rotated by being pressed by the engagement member 31, and a stable engagement state can be maintained.

  When the engaging portion 21c and the engaging protrusion 31a are set to the engaged state, the sleeve 2 and the hub 3 have already started to rotate so that the rotational difference is reduced. The engagement state can be smoothly realized without occurrence. Further, the rotational power is efficiently transmitted between the input side and the output side depending on the engaged state, and a stable engaged state can be maintained. When releasing the engaged state, the rotation friction clutch 10 is released while maintaining the rotation, so that a smooth releasing operation can be performed.

  Further, since the rotational friction clutch 10 can be operated by the rotation operation of the engagement operation member 21 and the engagement operation with the engagement portion 30 can be performed, the member such as a piston is pivoted like a conventional clutch device. A space for moving in the direction becomes unnecessary, and the apparatus can be configured compactly.

  The operating part 20 having the engaging operating member 21 and the engaging part 30 having the engaging member 31 may be provided on either the input side member or the output side member for transmitting rotational power. Is provided on one of the input side member and the output side member and is set so as to be linked to the rotation operation around the rotation center axis, and the engaging portion 30 is provided on the other of the input side member or the output side member and is the center of rotation. What is necessary is just to set so that it may link with the rotation operation | movement centering on an axis | shaft.

  In the above-described example, the description has been made based on the clutch device. However, the rotating device includes a plurality of rotating members that are rotatably mounted around the rotation center axis, and transmits the driving force of the rotation drive shaft via these rotation members. The present invention can be applied to any apparatus. For example, it can be applied to devices such as a transmission, a torque converter, a starting clutch device, and a braking device such as a brake.
