になつている。 First, the hydraulic clutch shown in FIG. 1 sucks hydraulic oil from an oil pan 1 of a marine engine (not shown) using a gear pump 2, and increases the pressure as indicated by arrow I from an oil supply path 5 through which a pressure regulating valve 3 and an oil filter 4 are interposed. Alternatively, the pressure-regulated hydraulic oil is introduced into the pressure regulating valve 6 that operates in the pressure reduction direction of arrow D, and the pressure-regulated hydraulic oil is passed from the port 16 to the oil supply path 7.

A pilot valve 18 that can be electrically switched is provided in the clutch hydraulic direction switching device 12 surrounded by a dashed line, and this pilot valve 18 is indicated by the arrow F.
By moving forward in the forward direction or in the backward direction of arrow R, the hydraulic oil from the oil supply passage 5 is routed through the pilot valve 18 to either the forward switching valve 8 or the reverse switching valve 9, depending on the position. By pressing the valve ends of the valves against the spring force of the springs 19 provided respectively, either the forward switching valve 8 or the reverse switching valve 9 is opened, and as a result, the clutch is actuated.

出が可能となる。 Here, there is a difference between the reading of the potentiometer 21 and the hydraulic pressure P of the hydraulic oil regulated at the port 16.
There is a unique relationship as shown in the diagram shown in Figure 2,
The pressure P can be detected by reading the potentiometer 21.
次に、上記の構成からなる油圧クラツチの動作
及び制御について、その制御装置２４を示す第３

御のフローチヤートを参照しながら説明する。 Next, regarding the operation and control of the hydraulic clutch constructed as described above, the third section showing the control device 24 will be explained.
The explanation will be given with reference to the block diagram in the figure and the flowchart of control by the control device 24 in FIG.

No pressure is supplied to the forward cylinder 10 and the reverse cylinder 11, and the hydraulic pressure regulated at the port 16 is closed before the forward switching valve 8 and the reverse switching valve 9. At this time, the pressure regulating valve 6 maintains the high pressure P 1 with the servo valve 17 pushed out.
is held.
なお、この高圧P1はあらかじめ決められた圧

Ｄ変換器２５でＡ／Ｄ変換された値として制御装
置２４内の記憶装置２６に記憶されている。 Note that this high pressure P1 is a predetermined pressure and the output of the potentiometer 21 is adjusted to A/A in Fig. 3.
The value is A/D converted by the D converter 25 and stored in the storage device 26 in the control device 24.
また、制御装置２４内の演算装置２９は、中立
時にこの記憶値になるようにリレー(1)２７及びリ
レー(2)２８を介して圧力調整弁６を制御してい
る。 Further, the arithmetic unit 29 in the control device 24 controls the pressure regulating valve 6 via the relay (1) 27 and the relay (2) 28 so that the stored value is maintained at the neutral time.
次に、嵌入時には、手操作によりクラツチ位置
切換スイツチ３０により、前進用シリンダ１０ま
たは後進用シリンダ１１側にそれぞれ嵌入する入
力が制御装置２４に入ると、以下の動作を行な
う。 Next, at the time of fitting, when an input for fitting into the forward cylinder 10 or reverse cylinder 11 side is entered into the control device 24 by manual operation using the clutch position changeover switch 30, the following operations are performed.
即ち、制御装置２４は入力のあつた前進方向

リレー(2)２８を介し、圧力調整弁６を作動させ、
これもあらかじめ設定された低い圧力P2にポテ
ンシヨメータ２１の出力を読みながら下げる。 That is, the control device 24 operates the clutch hydraulic direction switching device 12 in the forward direction F or the reverse direction R where the input is received, and then waits for a waiting time T 2 preset according to the rotation speed of the marine engine and then switches the relay. (2) Activate the pressure regulating valve 6 via 28,
This is also lowered to a preset low pressure P2 while reading the output of the potentiometer 21.
なお、上記の待ち時間T2は嵌入時間T1を遅ら
せず、加えて舶用機関の場合の例えばプロペラ回
転の立上りが滑らかになるような嵌入シヨツクの
ない最適な時間が機関の回転数によつて得られる
ものである。 Note that the above waiting time T 2 does not delay the fitting time T 1 , and in addition, in the case of a marine engine, for example, the optimal time without a fitting shock, which smooths the rise of propeller rotation, depends on the engine rotation speed. That's what you get.
次に、あらかじめ設定された待ち時間T3だけ
待つてリレー(1)２７を介し圧力調整弁６を動作さ
せ、その油圧をポテンシヨメータ２１の出力と比
較しながら高圧P1に上昇する。 Next, after waiting for a preset waiting time T 3 , the pressure regulating valve 6 is operated via the relay (1) 27, and the oil pressure is increased to the high pressure P 1 while being compared with the output of the potentiometer 21.
なお、待ち時間T3は立上り時間T4を最適にす

数によつてあらかじめ得られているものである。 Note that the waiting time T3 is a value that optimizes the rise time T4 , and like the waiting time T2 , this value is also obtained in advance based on the engine speed.
また、第５図の上部に示すように油圧制御をし

速いので嵌入時のシヨツクが大きくなるのに対
し、一方、本発明のごとく制御装置２４で油圧を
調整する時は立上りが遅いので嵌入時のシヨツク
が少なくなる。 Moreover, as shown in the upper part of FIG. 5, when hydraulic control is not performed, the rise time is T 4 ', and the rise is fast, so the shock at the time of insertion is large. When adjusting the hydraulic pressure, the start-up is slow, so there is less shock when fitting.

を下げる。 That is, after waiting for a preset and memorized waiting time T2 depending on the engine speed, relay (2)2 is activated.
8, the pressure regulating valve 6 is operated, and the hydraulic pressure is immediately lowered to a low pressure P2 , which is also set and stored in advance, while comparing it with the output of the potentiometer 21.
なお、待ち時間T2は、嵌入時間T1を遅らせず、
加えてガラ音を発生させない最適な値が機関の回
転数によつて得られるものである。 Note that the waiting time T 2 does not delay the insertion time T 1 ;
In addition, the optimum value that does not generate rattling noise can be obtained by changing the engine speed.
また、低い圧力P3は、ガラ音が出ないために
下げねばならない圧力で、これもクラツチにより
前もつて得られている。 Also, the low pressure P 3 is the pressure that must be reduced in order to avoid rattling noise, and this is also already achieved by the clutch.

の動作にそなえることになる。 On the other hand, when an operation to return to neutral is input, the control device 24 operates the clutch hydraulic direction switching device 12 to neutral, and also switches the pressure regulating valve 6 to the relay (1) 27.
The pressure is quickly returned to the neutral state, high pressure P 1 , to prepare for the next operation.
従つて、本発明の油圧クラツチの嵌入シヨツク

ク防止装置。1 Consists of a clutch hydraulic direction switching device 12, a pressure regulating valve 6, a hydraulic pressure detector 22, and a control device 24, and the clutch hydraulic direction switching device 12 is connected to the oil supply path 5.
A forward switching valve 8 is energized so that the port 16 of the pressure regulating valve 6 can selectively communicate with the forward cylinder 10 or the reverse cylinder 11 depending on the switching of the pilot valve 18. and a reverse switching valve 9, the pressure regulating valve 6 is connected to a drive device so as to pressure-regulate the hydraulic pressure from the oil supply path 5 to the forward switching valve 8 or the reverse switching valve 9 from a port 16. 14, the hydraulic pressure detector 22 works in conjunction with the servo valve 17 to output the position of the servo valve 17 to the control device 24 as an actual hydraulic pressure signal, The control device 24 compares the signal from the set pressure storage device 26 and the signal from the oil pressure detector 22 according to the setting of the clutch position changeover switch 30, and controls the pressure regulating valve 6 to the drive device 14 so as to approach the set pressure. A device for preventing jamming of a hydraulic clutch which is driven by twisting.
