Description

Clutch {Clutch}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a clutch capable of arbitrarily regulating a constant power to the driving side, and more particularly, to a clutch in which a gear system provided on an shaft prevents friction loss during a power transmission process.

In general, the clutch is provided on a path that converts thermal energy and electric energy into kinetic energy and has a driving force, and has a power interruption function to control the driving force.

Clutch having such a function is roughly divided into friction type and fluid type by its structure and operation method.

However, the clutch according to the conventional type has a problem in that friction loss occurs in the process of controlling power.

That is, the friction clutch applied to the friction type is coupled between the flywheel and the pressure plate while the clutch disk is coupled to the clutch shaft as a spline, so that the rotation of the flywheel is transmitted to the transmission through the clutch shaft by the friction force.

Therefore, in the process of power interruption, odor caused by burnout caused by friction loss of the pressure plate, frequent parts replacement and power interruption are not certain.

In the case of the torque converter applied to the fluid type, the frictional resistance of the fluid is generated between the input shaft and the output shaft, resulting in energy loss.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and an object of the present invention is to provide a gear system on an axis that transmits a constant power to the drive side, and the gear system maintains a minimum resistance when the load system is not loaded. The present invention provides a clutch that minimizes friction loss by transmitting power with a gear system stopped.

The present invention for realizing the above object is connected to the input side to which a constant power is transmitted and the clutch housing having a receiving space, the clutch cover for covering the receiving space of the clutch housing to maintain the airtight, and is projected through the clutch cover Lubrication path between the main shaft gear provided with the main shaft to be freely accommodated in the clutch housing, the planetary gears freely accommodated in the clutch cover and the clutch housing by maintaining a constant interval in engagement with the main shaft gear, and the planetary gears and the main shaft gear. Lubrication holes are formed in communication with the planetary gear and the main shaft gear so as to achieve a lubrication hole embedded in the clutch housing, and the lubrication path between the main gear and the planetary gear formed by the lubrication hole of the lubrication hole is blocked or released. An intermittent valve that forms an intermittent feature is a characteristic configuration.

The technical idea of the present invention by the above-described configuration is that the clutch valve including the planetary gear and its organic connection part rotate in the same direction when the intermittent valve is open at no load, so that the flow path is free from lubrication between the planetary gear and the main shaft gear. Since the planetary gear and the main shaft gear is rotated attenuated power is not made.

In addition, when the intermittent valve is blocked under load, the lubricating oil is stagnated between the planetary gear and the main shaft gear to maintain the vacuum state. Therefore, the planetary gear and the main shaft gear rotate in the same direction as the clutch housing without frictional rotation to transmit power.

The lubricating hole 50 formed in the clutch housing 10 by forming a lubricating hole 51 communicating with the 30 is formed, and the main shaft 30 and the planetary gear 40 formed by the lubricating hole 51 of the lubricating hole 50. Intermittent valley to block or release the lubrication path (52) between the) to achieve the interruption of power through the main shaft gear (30) It is made into a characteristic structure.

The main shaft gear 30 and the planetary gear 40 are provided with shafts 38 and 41, respectively, and the shafts 38 and 41 are supported by the clutch cover 20 and the clutch housing 10. Shaft grooves 13 and 25 are formed.

In addition, the clutch housing 10 and the clutch cover 20 opposite thereto are formed with threaded holes 12 and 26 and are coupled with the screw through them. Coupling of the clutch housing 10 and the lubrication tool 50 is formed by forming a key groove 14 and a key protrusion 53 on the opposite surface.

In addition, the lubricating oil replenishing means filled between the main shaft gear 30 and the planetary gear 40 has a flow path 32 having an injection passage 33 and a discharge passage 34 penetrating in both directions downward through the upper side of the spindle 31. In addition, the lubricating oil discharged through the discharge path 34 is distributed between the planetary gears 40 and the main shaft gear 30 so that the discharge path 34 and the planetary gear ( 40 and a lubricant distribution channel 24 communicating the adjacent position of the main shaft gear (30).

In addition, the oil cover 22 is formed in the clutch cover 20 to extend the adjacent surface of the distribution channel 24 adjacent to the discharge path 34 to smoothly inject the lubricating oil. At this time, the flow path 32 forms an expansion space 35 extending a predetermined position of the flow path 32 as a non-return valve for preventing backflow of the injected oil, and the steel balls 36 are formed in the expansion space 35. In addition to the built-in, an elastic member 37 is provided to elastically support the steel ball 36 in the direction of the injection path 33 so that the steel ball 36 can tightly block the flow path 32.

The intermittent valve has a clutch housing 10 and a clutch cover on the lubrication path 52 in the lubrication hole 51 in a state in which an arc-shaped mating surface 61 is formed on one side and the other side is in close contact with the main shaft gear 30. 20 and a shielding film 60 mounted in a supported state, and having a predetermined diameter to be joined to the mating surface 61 of the barrier film 60, and facing the mating surface 61 at a predetermined position of the outer diameter. Forming the cutting surface 71 is supported by the clutch housing 10, the upper side of the rotary holes 70 protruding through the clutch cover 20, the outer diameter and the cutting surface 71 of the rotary hole 70 Located on the mating surface 61 of the blocking film 60, it consists of operating means for rotating the rotary sphere 70 so that the lubrication path 52 is intermittent.

And the operation means enters the lifting plate 80, which is lifted by the external operation to freely lift the tubular body 21, which is discharged from the clutch cover 20, and penetrates the rotary hole 70 through the lifting plate 80 To form a helical guide groove 72 in the outer diameter of the rotary ball 70, and to enter the guide groove 72 to provide a rotational force to the rotary ball 70 in accordance with the lifting of the elevating plate 80 It is made by forming a guide projection 82 in the through-hole 81 of the elevating plate 80 through which the rotary hole 70 passes.

Guide pipe 82 is formed on the outer diameter of the tubular body 21 and is fitted to the fixing protrusion 23 on the opposing surface of the elevating plate 80 fitted to the tubular body 21 so as not to cause free lifting or transverse flow. The fixing groove 73 is formed.

Referring to the operation of the present invention by the above configuration as follows. First, the non-return valve is a steel ball 36 is elastically supported by the elastic member 37 in the injection path 33 direction through the flow path (32) Backflow of the lubricating oil toward the injection passage 33 side is prevented.

2 and 4, the intermittent valve is in an open state.

That is, the elevating plate 80 is positioned above the rotary tool 70 by the operation means, so that the lubrication path is opposed to the cut surface 71 of the rotary tool 70 and the mating surface 61 of the blocking film 60. 52 is in an open state.

In this state, when the clutch housing 10 rotates by a constant power, all members including the clutch housing 10, the clutch cover 20, the lubrication tool 50, and the planetary gear 40 rotate similarly.

The planetary gear 40 rotates by rotating the main shaft gear 30 while the lubrication path 52 is opened, whereas the main shaft gear 30 has no rotational force with respect to the planetary gear 40. Will not rotate. The power is cut off. That is, the incision surface 71 of the outer diameter of the rotation hole 70 faces the mating surface 61 of the blocking film 60 to have a predetermined distance between the rotation hole 70 and the blocking film 60. Lubricating oil flow is made through this. The planetary gear 40 embedded in the clutch housing 10 rotates while rotating against the rotation of the clutch housing while being bitten by the main shaft gear 30 by the lubricating action of the lubricating oil. At this time, the main shaft gear 30 is rotated in a state in which the planetary gear 40 is bitten by the main shaft gear 30 about the shaft 41, thereby making a stationary state or a slight rotation to clutch the clutch housing 10 as much as the rotational speed. Power transmission to the main shaft 31 through the housing 10 is not made.

3 and 5 in this state, the lifting plate 80 is lowered by the operation means.

The rotary ball 70 is supported by the guide groove 72 in the guide projection 82 is rotated so that the outer diameter of the rotary ball 70 is in close contact with the mating surface 61 of the blocking film 60, the lubrication path 52 To block.

Accordingly, the lubricating oil on the lubrication path 52 is maintained in a vacuum state without being rotated. The main shaft gear 30 including the planetary gear 40 transmits the rotational force while rotating in the same direction as the clutch housing 10. That is, the three planetary gears 40 are embedded in the clutch housing 10. In the process of changing the position according to the rotation of the low clutch housing 10 maintains a vacuum state in which lubricating oil does not flow between the main shaft gear (30). Therefore, the main shaft gear 30 and the planetary gear 40 have a rotation speed that rotates integrally with the clutch housing 10 without rotating about the shafts 38 and 41, so that the rotation of the clutch housing 10 Power is transmitted through the main shaft 31. In addition, when the lifting plate 80 is raised, the rotary ball 70 moves as described above to cut the mold mating surface 61 and the rotary ball 70 of the blocking film 60. Surface 71 is opposed to have a flow of lubricating oil, the power is cut off. On the other hand, the operation means for achieving the rise and fall by operating the elevating plate 80 can be realized through a connection structure of a known clutch, which is a manual vehicle In the case of the lifting plate 80 may be made by connecting the clutch pedal, in the case of the vehicle amount may be electronically controlled by an automatic transmission.

The present invention includes a gear system on the shaft for transmitting a constant power to the drive side, and the gear system maintains a minimum resistance when the gear system is unloaded, and transmits the power in a state in which the gear system is stopped at the time of loading, thereby reducing the frictional loss. There is an effect that the power is cut off and transmitted accurately without power loss.

In addition, there is a common advantage in gear and electronic.
