Description

  The present invention relates to a clutch device for switching transmission of power to a transmission having two input shafts using hydraulic pressure.

  In general, in a motorcycle such as a motorcycle or a buggy, a clutch device is used to transmit or cut off power from an engine to a transmission. The clutch device includes a clutch housing connected to the crankshaft side of the engine, an output-side rotating body connected to the transmission side, a clutch portion for transmitting and shutting power between them, and a clutch portion. And a pressure plate for pressing. The clutch part has the 1st clutch plate supported by the clutch housing, and the 2nd clutch plate supported by the output side rotary body.

  These clutch plates are brought into pressure contact with a pressing member such as a spring through a pressure plate, whereby the rotation of the crankshaft is transmitted to the transmission side. When the clutch is turned off (power transmission is cut off), the release mechanism is operated by the driver holding the clutch lever. The release mechanism releases the pressing of the pressing member against the clutch plate. Power transmission between the two clutch plates is cut off.

  However, in the above-described clutch device, the transmission of power is temporarily interrupted when shifting, and this torque loss reduces operability.

Therefore, a twin clutch device having two clutch portions has been proposed as a clutch device.
JP 2007-177905 A

  In the conventional twin clutch device, when the hydraulic pressure is not supplied, the clutch portion is disconnected. For this reason, for example, when the engine is stopped, the two clutch portions are in an open state, and when starting the engine, a so-called pushing, in which the vehicle is forcibly moved in the clutch connected state and the engine is reversely driven cannot be performed. Therefore, it is necessary to provide a motor or the like for starting the engine, the number of parts increases, and the structure becomes complicated.

  Moreover, in the conventional twin clutch apparatus, since it is necessary to provide two clutch parts, there exists a tendency for an apparatus to enlarge.

  The subject of this invention is providing the clutch apparatus which can simplify the structure of a vehicle.

  Another object of the present invention is to reduce the size of the clutch device.

  A clutch device according to the present invention is a clutch device for switching transmission of power to a transmission having first and second input shafts using hydraulic pressure. The clutch device includes an input rotating body provided to receive power, a first clutch portion, a second clutch portion, a first operation mechanism, and a second operation mechanism. The first clutch portion can transmit power from the input rotating body to the first input shaft by a frictional force. The second clutch portion has an elastic member supported by the input rotator, and can transmit power from the input rotator to the second input shaft by a frictional force generated by the pressing force of the elastic member. The first operating mechanism is a mechanism that switches between transmission and interruption of power in the first clutch portion, and generates a pressing force that acts on the first clutch portion by hydraulic pressure. The second operation mechanism is a mechanism that switches between transmission and interruption of power in the second clutch portion, and changes the pressing force of the elastic member that acts on the second clutch portion by hydraulic pressure.

  In this clutch device, when the hydraulic pressure is not supplied, the second clutch portion is connected by the elastic force of the elastic member, so that the engine can be reversely driven when the engine is started. As a result, it is not necessary to provide a driving device such as an engine starting motor, so that the structure of the vehicle can be simplified.

  The clutch device according to the present invention is a clutch device for switching power transmission to a transmission having first and second input shafts using hydraulic pressure. The clutch device includes an input rotating body provided to receive power, a first clutch portion, a second clutch portion, a first operation mechanism, and a second operation mechanism. The first clutch portion can transmit power from the input rotating body to the first input shaft by a frictional force. The second clutch portion is disposed on the first axial side of the first clutch portion, and can transmit power from the input rotating body to the second input shaft by a frictional force. The first operating mechanism is a mechanism that switches between power transmission and shut-off in the first clutch part, and has a first intermediate member on which a tensile force acts when switching the state of the first clutch part. The second operating mechanism is a mechanism that switches between power transmission and shut-off in the second clutch portion, and has a second intermediate member on which a pulling force acts when switching the state of the second clutch portion.

  In this clutch device, a tensile force acts on the first intermediate member of the first operating mechanism, and a tensile force acts on the second intermediate member of the second operating mechanism. For this reason, compared with the case where compressive force acts on the 1st and 2nd intermediate member, the intensity | strength of a 1st and 2nd intermediate member can be set low, and the dimension of a 1st and 2nd intermediate member can be made small. be able to. That is, this clutch device can be miniaturized.

  Since the clutch device according to the present invention has the above-described configuration, the structure of the vehicle can be simplified.

  Since the clutch device according to the present invention has the above-described configuration, it can be downsized.

The diaphragm spring 62 is compressed between the flywheel 21 and the second pressure plate 61.

  The second clutch portion 6 has a back torque limiter 69 (BTL) that limits the transmitted power. Specifically, the back torque limiter 69 is a mechanism that mechanically operates when the transmitted power exceeds a predetermined value when power is transmitted in the reverse direction from the second input shaft 4 to the input rotating body 2. The back torque limiter 69 limits the transmission power during reverse driving.

  In FIG. 1, power is transmitted from the input rotating body 2 to the second input shaft 4 by the second clutch portion 6. In FIG. 3, power transmission from the input rotating body 2 to the second input shaft 4 is interrupted by the second clutch portion 6.

The drive rod 84 is inserted into a hole 22 a formed in the support member 22 and can come into contact with the outer peripheral portion of the second operation plate 83.

<Basic operation of clutch device>
The basic operation of the clutch device 1 will be described with reference to FIGS.

(1) When the engine is started Since the hydraulic device is not driven when the engine is stopped, no hydraulic pressure is applied to the first actuator 9 and the second actuator 10. For this reason, as shown in FIG. 1, the input rotor 2 is not connected to the first input shaft 3 by the first clutch portion 5, and the input rotor 2 is connected to the second input shaft 4 by the second clutch portion 6. It is connected.

  In the clutch device 1, when the engine is started, the input rotor 2 is connected to the second input shaft 4 by the second clutch portion 6. Therefore, if the transmission is switched to the second speed state, for example, the clutch lever The engine can be reversely driven (so-called pushing) while holding

  Since the clutch lever is held after the engine is started, the hydraulic oil is supplied from the hydraulic device to the second actuator 10 and the connected state of the second clutch portion 6 is released. Specifically, when hydraulic oil is supplied to the second actuator 10, the second cylinder 102 moves to the first side in the axial direction. Accordingly, the second rod 81 and the second operation plate 83 move to the first axial direction, and the second pressure plate 61 is pushed to the first axial direction via the drive rod 84. As a result, the second input friction plate 64 and the second output friction plate 63 can be rotated relative to each other, and the second clutch portion 6 is in a disengaged state.

(2) At the time of start When the vehicle starts at the first speed, power transmission at the first clutch portion 5 is started. Specifically, for example, when the driver selects the first speed, hydraulic oil is gradually supplied to the first actuator 9, and the first cylinder 92 moves to the first side in the axial direction. Accordingly, the first rod 71 and the first operating plate 73 move to the first axial direction, and the disk lever 52 is pushed to the first axial direction by the first operating plate 73. As a result, the disc lever 52 comes into contact with the first pressure plate 51, and the pressing force is gradually transmitted from the first operating plate 73 to the first pressure plate 51 via the disc lever 52. The first input friction plate 54 and the first output friction plate 53 are gradually sandwiched between the second output member 33.

  Thereby, power is gradually transmitted from the input rotating body 2 to the first input shaft 3 by the frictional force generated between the members. For example, the pressure of the hydraulic oil is controlled by a control device (not shown) according to the engine speed, and the pressing force applied from the first operating mechanism 7 to the first clutch unit 5 is adjusted.

  Thus, in this clutch apparatus 1, since the 1st clutch part 5 which can adjust the transmitted motive power comparatively easily with oil_pressure | hydraulic is used at the time of start, smooth start is attained.

  Further, as shown in FIG. 4, at the time of starting, the pressure of the hydraulic oil supplied to the first actuator 9 is limited by the control device, and is transmitted from the input rotating body 2 to the first input shaft 3 by the first clutch unit 5. The power is smaller than the required maximum torque. Thereby, rapid power transmission can be suppressed, and a smoother starting operation is possible.

  Here, the first vertical axis of the graph shown in FIG. 4 indicates the torque (clutch torque) transmitted by the first clutch unit 5 or the second clutch unit 6, and the second vertical axis indicates the diaphragm spring 62. The pressing force is shown. The horizontal axis indicates the stroke and operating time of the first operating plate 73 and the second operating plate 83.

  During the first speed travel, the transmission is switched to the second speed state in the system on the second input shaft 4 side.

(3) Operation at the time of up-shifting For example, when shifting up from the first speed to the second speed, the power transmission by the first clutch unit 5 is released, and at the same time, the power transmission by the second clutch unit 6 is started. The Specifically, the hydraulic pressure acting on the first actuator 9 is released, and the pressing force applied from the first operating mechanism 7 to the first clutch portion 5 is released. Thereby, the power transmission by the 1st clutch part 5 from the input rotary body 2 to the 1st input shaft 3 is interrupted | blocked.

  At substantially the same time, the hydraulic pressure acting on the second actuator 10 is released, and the pressing force applied from the second operating mechanism 8 to the second pressure plate 61 and the diaphragm spring 62 is released. As a result, the diaphragm spring 62 presses the second pressure plate 61, and power is transmitted from the input rotating body 2 to the first input shaft 3 by the second clutch portion 6.

  Since the system on the second input shaft 4 side is switched to the second speed, switching from the first speed to the second speed can be performed instantaneously by the above operation.

  Further, when shifting up from the second speed to the third speed, the power transmission by the second clutch portion 6 is released, and at the same time, the power transmission by the first clutch portion 5 is started. Specifically, hydraulic oil is supplied from the hydraulic device to the second actuator 10, and a pressing force is applied from the second operating mechanism 8 to the second pressure plate 61 and the diaphragm spring 62. As a result, the second pressure plate 61 moves toward the first side in the axial direction against the elastic force of the diaphragm spring 62, and the power transmission in the second clutch portion 6 is interrupted.

  At substantially the same time, hydraulic fluid is supplied from the hydraulic device to the first actuator 9, and a pressing force is applied from the first operating mechanism 7 to the first clutch unit 5. Thus, power is transmitted from the input rotating body 2 to the first input shaft 3 by the first clutch unit 5.

  Since the system on the first input shaft 3 side in the transmission is switched to the third speed, the switching from the second speed to the third speed can be instantaneously performed by the above operation.

(4) Operation at the time of downshifting For example, when shifting down from the third speed to the second speed, the power transmission by the first clutch unit 5 is released, and at the same time, the power transmission by the second clutch unit 6 is started. The Specifically, the hydraulic pressure acting on the first actuator 9 is released, and the pressing force applied from the first operating mechanism 7 to the first clutch portion 5 is released. Thereby, the power transmission by the 1st clutch part 5 from the input rotary body 2 to the 1st input shaft 3 is interrupted | blocked. In the transmission, the system on the second input shaft 4 side is switched to the second speed in accordance with the shift change operation of the driver.

  At substantially the same time, the hydraulic pressure acting on the second actuator 10 is released, and the pressing force applied from the second operating mechanism 8 to the second pressure plate 61 and the diaphragm spring 62 is released. As a result, the diaphragm spring 62 presses the second pressure plate 61, and power is transmitted from the input rotating body 2 to the first input shaft 3 by the second clutch portion 6.

  With the above operation, switching from the third speed to the second speed can be performed instantaneously.

(5) Back torque limiter During the downshift described above, power may be transmitted from the second input shaft 4 to the input rotating body 2 by engine braking. When this power is large, for example, the tire may slip, but the torque transmitted to the input rotating body 2 by the back torque limiter 69 of the second clutch portion 6 is limited to a predetermined value. Specifically, as shown in FIG. 4, when the transmission power in the second clutch portion 6 is indicated by a one-dot chain line, during positive driving (when power is transmitted from the input rotating body 2 to the second input shaft 4). However, during the reverse drive (when power is transmitted from the second input shaft 4 to the input rotating body 2), a back torque limiter can be transmitted. Only the optimum torque set by 69 is transmitted. Thereby, the slip at the time of downshifting can be prevented.

  In the clutch device 1, a back torque limiter can be realized also in the first clutch portion 5. Specifically, in the clutch device 1, the power transmitted by the first clutch unit 5 is limited by adjusting the amount of hydraulic oil supplied to the first operating mechanism 7.

  As shown in FIG. 4, at the time of deceleration, the power transmitted by the first clutch unit 5 is supplied to the first actuator 9 so that the allowable transmission torque of the back torque limiter 69 of the second clutch unit 6 becomes substantially the same. The hydraulic oil pressure is adjusted. Thereby, the slip at the time of downshift can be prevented like the case of the 2nd clutch part 6. FIG.

<Features>
The features of the clutch device 1 are as follows.

(1)
In this clutch device 1, the second clutch portion 6 is connected by the elastic force of the diaphragm spring 62 when hydraulic pressure is not supplied, so that the engine can be reversely driven when the engine is started. As a result, the engine can be started even if the hydraulic device is out of order. In addition, since it is not necessary to provide a driving device such as an engine starting motor, the structure of the vehicle can be simplified.

(2)
In this clutch device 1, the magnitude of power transmitted by the first clutch portion 5 can be directly adjusted by hydraulic pressure, so the magnitude of power is indirectly adjusted by adjusting the pressing force of the diaphragm spring 62. Compared to the configuration, the transmitted power can be finely adjusted. For this reason, for example, the 1st clutch part 5 is used at the time of start, and a smooth start is attained.

(3)
In the clutch device 1, a tensile force acts on the first rod 71 when the first operating mechanism 7 transmits a pressing force to the first clutch portion 5. A tensile force acts on the second rod 81 when the second operating mechanism 8 changes the pressing force of the diaphragm spring 62. For this reason, compared with the case where a compressive force acts on the 1st rod 71 and the 2nd rod 81, the intensity | strength of the 1st rod 71 and the 2nd rod 81 can be set low. Thereby, the dimension (more specifically, outer diameter or thickness) of the 1st rod 71 and the 2nd rod 81 can be made small, and the size reduction of the clutch apparatus 1 is attained.

  In particular, since the first rod 71 has the cylindrical portion 71a and the second rod 81 is inserted into the cylindrical portion 71a, the clutch device 1 can be further downsized.

(4)
In this clutch device 1, since the first actuator 9 and the second actuator 10 are arranged on the first axial side of the first clutch portion 5 and the second clutch portion 6, the two actuators are integrated into one place. Therefore, downsizing of the entire apparatus can be expected.

(5)
In this clutch device 1, since the drive rod 84 is inserted into the hole 22 a provided in the support member 22, it is possible to prevent the outer dimensions of the clutch device 1 from being increased by the drive rod 84.

(6)
In the clutch device 1, in addition to the second clutch portion 6 having a mechanical back torque limiter 69, the back torque limiter is also realized by controlling the hydraulic pressure in the first clutch portion 5. . As a result, transmission of excessive torque during reverse driving can be prevented at any shift speed, and tire slipping and the like can be prevented.

  In particular, since the allowable transmission torque of the back torque limiter can be freely adjusted by hydraulic control, it is possible to set an appropriate allowable transmission torque according to the traveling state of the vehicle.

<Other embodiments>
The specific configuration of the present invention is not limited to the above-described embodiment, and various changes and modifications can be made without departing from the spirit of the present invention.

(1)
In the above-described embodiment, the material of the first input friction plate 54, the first output friction plate 53, the second input friction plate 64, and the second output friction plate 63 is a carbon composite material, but other materials may be used. Good. For example, the material of these friction plates may be a metal or organic material. Moreover, the number of these friction plates is not limited to the quantity of the above-mentioned embodiment, What is necessary is just one at least.

(2)
In the above-described embodiment, a clutch device used for a motorcycle is assumed, but a clutch device for other purposes may be used.

(3)
The second clutch portion 6 may be a hydraulic clutch in the same manner as the first clutch portion 5. Here, a clutch device 101 according to another embodiment will be described with reference to FIG. In addition, the same code | symbol is attached | subjected to the structure which has the substantially same function as the above-mentioned embodiment, and the detailed description is abbreviate | omitted.

  In the clutch device 101 shown in FIG. 5, the second clutch portion 106 has a second disc lever 162 instead of the diaphragm spring 62. The second disc lever 162 is supported by the support member 22 so as to be elastically deformable. The outer peripheral portion of the second disc lever 162 can contact the drive rod 84. When the drive rod 84 is pushed to the first axial side by the second operating plate 83, the outer peripheral portion of the second disc lever 162 is pushed to the first axial side via the drive rod 84. As a result, the contact point between the flywheel 21 and the second disc lever 162 serves as a fulcrum, and the second pressure plate 61 is pushed to the second axial side by the second disc lever 162. Thereby, the 2nd clutch part 106 will be in a connection state.

  In this case, the power transmitted by the second clutch unit 106 can be adjusted by the pressure of the lubricating oil supplied to the second actuator 10. Thereby, similarly to the 1st clutch part 5, a back torque limiter is realizable by hydraulic control.

  Further, since the allowable transmission torque of the back torque limiter can be freely adjusted by hydraulic control, it is possible to set an appropriate allowable transmission torque according to the traveling state of the vehicle.
