るものである。DETAILED DESCRIPTION OF THE INVENTION According to the present invention, the clutches of two-wheeled motor vehicles, which are always engaged by a pressing spring, are always engaged by a suppressing spring and released by a clutch lever when changing gears. In large two-wheeled motor vehicles, it is necessary to increase the clutch capacity accordingly, but there is a limit to how much the pressing force of the pressing spring can be increased for this purpose. That is,
This is because manual operating force of the clutch lever cannot be forced, and when the lever ratio is increased, the operating stroke increases, which may even cause inconvenience. Therefore, the clutch capacity is increased by increasing the number of multi-disc clutches, and the force of the suppression spring is kept at an appropriate level. The disadvantages of this method are that it causes problems with clutch disengagement, increases the width of the engine, and increases costs. In view of these shortcomings, the clutch capacity was increased by strengthening the suppression spring without increasing the number of clutch plates, and in addition, the operating stroke and operating force of the clutch Leno ζ- were appropriately suppressed to enable sensitive control of this clutch. The present invention aims to provide a clutch operating device for a two-wheeled motor vehicle.
上記の目的を達成するため、この発明の自動2輪車のク

構が可動部材に係合すると同時に油圧駆動機構が駆動を
開始するようにする。In other words, the movable release member for opening the clutch, which is always connected by a pressing spring, is provided with a hydraulic drive mechanism for hydraulic pressure weaker than the elasticity of the pressing spring, while the release driving mechanism by the manual clutch lever and the movable A play stroke is provided between the member and the movable member, and this play stroke controls the valve device of the hydraulic drive mechanism, and the hydraulic drive mechanism is driven at the same time as the release drive mechanism engages the movable member. to start.

してフルクラッチに戻る。With this configuration, when the manual Kujich lever is slightly operated to exceed the amount of play, the hydraulic drive mechanism is activated, and the manual operating force and hydraulic pressure work together to act on the clutch. The hydraulic pressure is constant, and the clutch can be controlled at will by increasing or decreasing the manual operating force by subtracting that amount. Also, since the hydraulic pressure is weaker than the suppression spring, if the operating force is weakened, the clutch will immediately return to engagement. In this case as well, the amount of torque transmitted in the half-clutch state can be controlled according to the adjustment of the operating force, and when the release drive mechanism separates from the movable member, the hydraulic pressure stops and the state returns to the full clutch state.

である。As described above, by using the clutch operating device for a two-wheeled motor vehicle according to the present invention, a considerably large force can be controlled by a force adapted to manual operation, so the number of clutch plates can be reduced by increasing the size of the suppression spring. Therefore, the clutch can be easily disengaged, and the engine width can be made more compact to reduce weight, which helps reduce costs. The hydraulic drive mechanism only needs to obtain a constant hydraulic pressure, and the valve device only needs to have a simple function of opening and closing, so unlike a mechanism that controls hydraulic pressure, it has a simple structure and is easy to install. It is particularly suitable as a clutch operating device for two-wheeled motor vehicles that require a large and large-capacity clutch.

ズ部材を駆動する。FIG. 1 illustrates a clutch mechanism and a release mechanism of a two-wheeled motor vehicle. The clutch mechanism 1 is equipped at the end of a shaft 2, has a driving friction plate 3 and a driven friction plate 4 stacked on each other, and is pressed by a bushing plate 6 elastically loaded with a clutch spring 5.
Always connected. A bushing rod 7 is slidably inserted into the axis of the shaft 2, and its tip engages with the center of the bushing plate 6 via a bushing pin 8. When the bushing rod 7 is pushed, the bushing plate 6 moves away from the friction plate against the clutch spring 5, and the clutch mechanism 1 is released. A release drive mechanism 9 is provided on the opposite side of the shaft 20. This release drive mechanism 9 is fixed to a case or the like, and has a bushing screw 11 screwed into an internal thread 10. The bushing screw 11 is swung by a lever 12 that is linked to a clutch lever ζ-, and its axial displacement causes the release. Drive the member.

Waを越ないように設定する。A cylinder 14 is provided concentrically with the shaft 2, and the tip of a two-stone rod 15a of a bushing piston 15 housed in the cylinder 14 is brought into contact with the tail end of the bushing rod 7. A piston valve 16 is housed in the cylinder 14 behind the bush piston 15. The gusset valve 16 is urged rearward by the return spring 17, and the bushing member 18'i<

A hydraulic inlet 19 opens into the cylinder 14 at the rear end of the bushing 6, while a hydraulic outlet opens at the tail end of the bushing stone 15. The gas cylinder valve 16 has a communication hole 2 that communicates with the front and rear.
There is 1. Further, the cylinder 14 is provided with a relief valve η, and its pressure spring η controls the cylinder internal pressure to a constant level. The magnitude of the oil pressure is set so that the pressing force wb generated on the bushing piston 15 does not exceed the force Wa of the clutch spring 5.

b+Weになるとブツシュピストン15がブツシュロッ
ド7を押し出してクラッチ機構1が開く。When the clutch lever is pulled and the release drive mechanism 9f is activated, the pistol valve 16 presses the return spring 17 and moves forward. The operating force at this time is extremely light. The piston valve 16 comes into contact with the bush piston 15 and presses it, making operation difficult. At this time, the hydraulic inlet 19 is opened, the hydraulic pressure output is closed (FIG. 2), and the hydraulic pressure wb, which is controlled at a constant level by the relief valve U, is applied to the bush piston 15. clutch spring 5
Since 0 force Wa>wb, the bushing piston 15 does not move, but the piston valve 16 continues to be released from the release drive mechanism 9.
A force Wc is added to the , which becomes larger and becomes Wa(W
When b+We is reached, the bushing piston 15 pushes out the bushing rod 7 and the clutch mechanism 1 opens.
