Abstract

PURPOSE: To provide a power clutch capable of simply connecting or disconnecting power via a switch action by fitting a compressing device to a high-speed rotation section, converting the driving force generated by the revolving speed difference between a drive shaft and a driven shaft into the compressed pressure, and adjusting the pressure via an electric motor. CONSTITUTION: When an electric motor 56 is started, a worm 54 drives a worm wheel 55, a needle valve protector 34 is pushed to open a needle valve, and the high-pressure air in a pressure adjusting chamber 51 is relieved. When an interlocked piston 21 is rotated, a planetary gear 6 is rotated and revolved on the sun gear 3 of a driven shaft 49, and the driving force of a drive shaft 2 is not transmitted to the driven shaft 49. When the electric motor 56 is reversely rotated, the needle valve is closed, and the planetary gear 6 is continuously rotated by the driving force generated by the revolving speed difference between the drive shaft 2 and the driven shaft 49. The piston 21 is operated, and the rotation of the planetary gear 6 is stopped when the pressure of the pressure adjusting chamber 51 is increased until the moment around the planetary gear 6 and the moment around the action point of the piston 21 are balanced. The sun gear is rotated at the same speed as the drive shaft 2, and the output of a prime mover is completely transmitted to the driven shaft 49.

A closure lid divided into two parts with a diameter for closing and protecting it is attached to the flywheel body with screws.

Then, a planetary gear drive shaft is provided inside the flywheel, the planetary gear is fitted and combined with the sun gear of the slave shaft, and a piston is attached through a crank pin provided in the planetary gear. The cylinder with the piston inserted is attached to the closing lid of the flywheel via the cylinder-rotating shaft.

Further, a high-pressure flexible pipe is connected to the exhaust valve mounted on the top of the cylinder, and is connected to a pressure adjusting chamber penetrating the closing lid of the flywheel with a mounting cap. Since this exhaust valve makes a swinging motion around the cylinder-rotation shaft, it is desirable that the position of the cylinder-rotation shaft is at the connection point between the exhaust valve and the high-pressure flexible pipe.

Further, the pressure adjusting chamber is formed in a cylindrical shape orthogonal to each other, a cylindrical annular air tank is provided in the circumferential direction centering on the driven shaft, and is attached with a screw and a nipple, and in the axial direction.

The tip moves only in the axial direction with respect to the mount,
A spring is pressed against the needle valve protector so that it can follow the rotation, and the mounting ball is fitted into the sudden closing prevention hole.

Further, regarding the drive of the needle valve protector for pressure adjustment, a worm wheel combined with a propelling screw independent of the driven shaft and fixed to another wall is used as an electric motor.
A worm gear directly connected to the turret drives it back and forth in the axial direction, and in order to avoid sudden closing of the needle valve, a half-clutch state is automatically created at the break of the operation, and a sudden blockage hole is created. Is installed in the needle valve mounting ball storage part of the needle valve protector.

Since the worm wheel is moved back and forth in the axial direction, the width of the worm wheel is widened by the amount of movement. Also, since it moves integrally with the needle valve protector in the axial direction while making contact,
A slip prevention groove is provided on the inside of the wheel, and the slip prevention projection of the needle valve protector is fitted into this groove.

Further, a flexible pipe connected to the screw portion of the air cleaner penetrating the closing lid of the flywheel with a mounting cap is connected to an intake valve mounted on the top of the cylinder to supply air. To do.

The compression device mounted on the high-speed rotating part has an even number of compression devices and has free ends. The piston is a connecting rod through a crank pin, and the cylinder is a connecting ring through a mounting flange. Connect to each other to straddle,

[0015]

The power clutch constructed as described above is
When the switch in the driver's seat is turned off, the electric motor starts, the worm gear drives the worm wheel, the needle valve protector is pushed, the needle valve is pushed open, and the pressure is released. When the high pressure air in the adjustment chamber is released from the exhaust hole to reduce the pressure and the piston of the interlocking compressor rotates, the planetary gear rotates and rotates on the sun gear of the driven shaft, so that the driving force of the original shaft is reduced. It is not transmitted to the shaft and the clutch is released.

When the switch is turned on, the electric motor reversely rotates, the needle valve is closed, and the planetary gear continues to rotate due to the driving force due to the difference in rotational speed between the original shaft and the slave shaft. ,
The piston acts and the pressure in the pressure regulation chamber increases until the moment around the planet gear due to the difference in the driving force between the original shaft and the slave shaft balances the moment around the action point of the piston. -The rotation of the sun stops and the sun gear of the slave shaft-
Starts rotating at the same speed as the original shaft, and the clutch is connected so that the output of the original power is completely transmitted to the secondary shaft.

When connecting the clutches, one of the needle valves of the interlocked even number of pressure adjusting chambers is different in depth of the sudden closing prevention hole so that sudden connection does not occur.
It is closed later, and the half-clutch state is maintained during this period, and smooth clutch engagement is performed.
