本発明は自動車用クラッチ装置等に利用できるフライホ
イール装置に関するものである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a flywheel device that can be used in automobile clutch devices and the like.

に渦巻バネ５が設けられている。FIG. 1 shows a conventional automobile clutch device proposed in Japanese Patent Publication No. 54-21, in which a first flywheel 2 is fixedly connected to an input shaft 1, and the power of the flywheel 2 is transmitted to a clutch cover 3. A spiral spring 5 is provided to connect the first and second flywheels 2 and 4.

クラッチを接続すると、入力軸１からの動力は直接第１
フライホイール２に伝達され、第１フライホイール２が
回転する。This spiral spring 5 is interposed between the first and second flywheels 2 and 4, and although not shown, its outer peripheral end is connected to the first flywheel 2.
The two flywheels are connected by being engaged with the second flywheel 4 and having the inner peripheral end thereof engaged with the second flywheel 4. If the clutch is connected here, the power from the input shaft 1 will be directly transferred to the first
The signal is transmitted to the flywheel 2, and the first flywheel 2 rotates.

る大きなショックを吸収するだけの容量はない。This rotation is then transmitted to the second flywheel 4, clutch cover 3, clutch disc 6, and drive input shaft 7. At this time, the clutch shock is absorbed while the power is transmitted from the first flywheel 2 to the second flywheel 4. 8 is a torsion spring which absorbs a certain amount of shock when the clutch is engaged, but does not have enough capacity to absorb the large shock caused by sudden engagement.

供せんとするものである。Therefore, the spiral spring 5 absorbs the clutch shock, and this spiral spring 5 is connected to the first and second flywheels 2,
Since there is insufficient force to keep the parts 4 connected together during driving, it has not been possible to obtain a large vibration absorption effect at all times. The present invention was proposed to solve the above-mentioned conventional drawbacks,
By applying a force in the direction in which the first and second flywheels approach each other using a spiral spring and using a friction member,
It is an object of the present invention to provide a flywheel device that can obtain stable hysteresis and always obtain a large vibration absorption effect.

A fixing hole 12 is provided.

Furthermore, the friction member 13 is attached to the second flywheel 10 by the bolt 1.
5 is pressed by a presser member 16 fixed by. 17 is a spiral spring, the outer peripheral end of which is connected to the first
It is locked to a flywheel 9, and the inner peripheral end is locked to a second flywheel 101 via a pin 19.

外周端１７ａは矢印×方向に中心より変位し、内周端１

にはなっていない。The spiral spring 17 is the main point of the present invention, and has the shape shown in FIG. 4 in the front view, but as can be seen from the side view in FIG.
The outer circumferential end 17a is displaced from the center in the arrow x direction, and the inner circumferential end 1
7b is displaced from the center in the direction of arrow Y and is not on the same plane.

ルは互に接近する状態で組付けられることになる。In order to incorporate this spiral spring 17 between the first flywheel 9 and the second flywheel 10, a force is applied to the pin 18 in the direction of arrow Z, and a force is applied to the pin 19 in the direction of arrow W. The spring 17 is installed in the same plane. Therefore, after assembly, a force in the direction of arrow X is generated at the outer peripheral end 17a of the spiral spring 17, and a force in the direction of arrow Y is generated at the inner peripheral end 17b. Therefore, the outer circumferential portion of the first flywheel 9 is pulled toward the second flywheel 10 by the outer circumferential end 17a of the spiral spring 17, and the inner circumferential portion of the second flywheel 10 is pulled from the inner circumferential end 17M of the spiral spring 17 to the first flywheel. Since it is pulled in the direction of the wheel 9, the first and second flywheels are assembled in a state where they are close to each other.

ク吸収効果が失なわれるようなことはない。In addition, although four spiral springs 17 are shown in FIG. 2, the number of spiral springs 17 may be two, three, or five or more. Furthermore, the flywheel device shown in FIG. 3 is explained in the case where it is applied to an automobile clutch, and the C side is the engine side and the D side is the clutch disk, but the present invention is not limited to this. It goes without saying that the present invention can also be applied to other rotational torque transmission devices. The present invention is constructed as described in detail above, and since the first and second flywheels receive force in the direction of approaching each other due to the spiral wheels, both flywheels do not separate during driving. , the shock absorption effect during rotational force transmission is not lost.

FIG. 6 is an explanatory diagram showing hysteresis F due to a spiral spring and hysteresis G due to a friction member, where T is torque and 8
indicates the marriage angle. The left half of Fig. 6 shows the case of engine braking (when force is applied from the opposite direction), and the spiral spring is in an expanded state.

ライホイール装置。1. A spiral spring is interposed between the first and second flywheels so that the outer circumferential end is engaged with the first flywheel, and the inner circumferential end is engaged with the second flywheel to connect the two flywheels. In a device that transmits rotational torque to a wheel through a second flywheel and absorbs shock during power transmission by the spiral spring, the spiral spring has an outer peripheral end and an inner peripheral end. When assembling the spiral spring, press the inner and outer circumferential ends inward, deform it so that it becomes coplanar, and install it between the two flywheels. The second flywheel is brought into contact with the other surface of the friction member disposed such that one surface is in contact with the inner surface of the first flywheel, and the first and second flywheels are brought close to each other. A flywheel device characterized by being connected via a spiral spring.
