Clutch Using Fluid Pressure {An Oil Clutch}

The present invention relates to a clutch using a fluid, and more specifically, to prevent noise and breakage occurring in a conventional clutch, as well as ensuring stability during operation of the clutch, the transmission rate of the drive shaft torque can be maximized. It relates to a clutch using a fluid.

Conventional clutches include gear clutches using gears, friction clutches, and fluid clutches using vortex phenomena of fluid. These clutches have different applications depending on the application.

However, the engagement clutch is to use the gear meshing, the transmission rate of the drive shaft torque is high, but the noise is generated during operation of the clutch, as well as the tooth is easily damaged.

In addition, the friction clutch is to use the friction force of the disk constituting the clutch, the noise generated during the operation of the clutch, but had a problem of low transmission rate of the drive shaft torque.

In addition, the fluid clutch rotates the impeller mounted on the driven shaft by using the vortex phenomenon of the fluid, and has a problem that the drive shaft torque is not completely transmitted to the driven shaft due to the vortex loss of the fluid during torque transmission. .

Accordingly, the present invention is invented to solve the above problems, by installing a clutch using the pressure of the fluid between the drive shaft and the driven shaft, to prevent noise and breakage generated in the conventional clutch, as well as the drive shaft torque It is an object to provide a clutch using the pressure of the fluid that can maximize the delivery rate.

In order to achieve the above object, the present invention provides a housing in which a driven shaft is fixed and an inner side of which is formed a gear chamber and a fluid chamber, and a main gear mounted to the gear chamber and connected to a drive shaft and both sides thereof. It is characterized in that it is composed of an auxiliary auxiliary gear, a pressing plate mounted on the fluid chamber and moved left and right to open and close the gear chamber, and moving means for moving the pressing plate.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

1 illustrates a clutch of the present invention, the configuration of which is as follows.

The driven shaft 200 is fixed and the housing 1 is formed therein the gear chamber 111 and the fluid chamber 121, and the main gear is mounted to the gear chamber 111 and connected to the drive shaft 100 ( G1) and an auxiliary gear G2 engaged to both sides thereof, a presser plate 2 mounted on the fluid chamber 12 to control the fluid in the gear chamber 111, and the presser plate 2 by the control unit or It is characterized by consisting of a moving means (3) for moving manually.

This will be described in more detail as follows.

FIG. 2 is a cross-sectional view taken along line AA of FIG. 1, and FIG. 3 is a cross-sectional view taken along line BB of FIG. 1, wherein the housing 1 includes a gear chamber 111 including a main gear chamber 111a and an auxiliary gear chamber 111b. A first housing 11, a second housing 121 mounted on one side of the first housing 11 and having a fluid chamber 121 therein, and closing the fluid chamber 121 in the center thereof. The third housing 13 is formed with a hole 131 into which the drive shaft 100 is inserted.

In addition, a through hole 21 into which the drive shaft 100 is inserted is formed at the center of the pressing plate 2 mounted on the fluid chamber 121. The diameter of the through hole 21 is the diameter of the drive shaft 100 inserted therein. By forming the fluid passage 211 to be relatively larger, it is to facilitate the movement of the fluid in the gear chamber 111 and the fluid chamber 121 during the movement of the pressing plate (2).

4 shows a moving means according to the present invention, wherein the moving means 3 is mounted on an outer side of the pressing plate 2 and has a horizontal axis 312 on which an eccentric cam 311 is mounted and a vertical axis located on both sides thereof. Cam shaft 31 composed of 313, and is inserted into the outer side of the housing 1 and moved to the left and right, the horizontal axis 312 and the vertical axis 313 of the cam shaft 31 is inserted into both the upper and lower portions of the inner hole It consists of a moving plate 32 is formed with a groove 321 so that. That is, after the horizontal axis 312 and the vertical axis 313 positioned at both ends of the horizontal axis 312 are inserted into the groove part 321, the vertical axis 312 passes through the groove part 321 horizontally. It is fixed through. Accordingly, as the movable plate 32 is moved, the vertical axis 313 of the cam shaft 31 is rotated, thereby causing the horizontal shaft 312 to be rotated so that the eccentric cam 311 mounted on the horizontal shaft 312 is rotated. , The pressing plate 2 is moved.

Hereinafter, the operational relationship of the present invention configured as described above are as follows.

2A shows the non-connected state of the drive shaft and the driven shaft. The eccentric cam 311 fixed to the cam shaft 31 is maintained by moving the moving plate 32 constituting the moving means 3 to the left. The pressing plate 2 mounted to the fluid chamber 121 opens one side of the gear chamber 111. Therefore, as the fluid in the gear chamber 111 is freely moved through the fluid chamber 121, the main gear G1 connected to the driving shaft 100 is rotated and the auxiliary gears (mounted on both sides of the main gear G1) ( G2) is idle due to the movement of the fluid.

That is, the housing 11 equipped with the auxiliary gear G2 engaged with the main gear G1 maintains a stationary state such that only the drive shaft 100 is rotated and the driven shaft 200 connected to the housing 11 is not rotated. It is to keep the clutch disconnected.

On the contrary, FIG. 2B shows a connection state between the drive shaft and the driven shaft. When the moving plate 32 constituting the moving means 3 is moved to the right through the control unit, the eccentric cam 311 fixed to the cam shaft 31 is shown. ) Moves the pressing plate 2 mounted to the fluid chamber 121 to the right through the rotation of the cam shaft 31 to close one side of the gear chamber 111. Therefore, the fluid entrained in the gear chamber 111 maintains a solid state, and the auxiliary gears which are mounted on the gear chamber 111 and connected to the drive shaft 100 and are rotated at the same time as the main gear G1 connected to the driving shaft 100 ( As G2 is revolved about the main gear G1 and the housing 1 is also rotated together, the driven shaft 200 connected to the housing 1 rotates in association with the driving shaft 100.

That is, the housing 11 equipped with the auxiliary gear G2 meshed with the main gear G1 maintains the rotational state, so that the driven shaft 200 connected to the housing 11 is simultaneously connected with the rotation of the drive shaft 100. It is to maintain the connection state of the rotating clutch.
