[Industrial applications]

 The present invention relates to a flywheel mounted on an output part of an internal combustion engine to stabilize the rotational fluctuation of the internal combustion engine and improve the performance of the internal combustion engine, and more specifically, to determine the weight of the flywheel and the state of the vehicle and the internal combustion engine. The present invention relates to a variable-capacity flywheel that changes in accordance with.

[0002]

[Prior art]

 Conventionally, a flywheel, which is attached to the output part of an internal combustion engine to stabilize fluctuations in the rotation of the internal combustion engine, has a fixed inertial weight, and the operating state during idling, acceleration, deceleration, etc. of the vehicle. It is not configured to adjust the inertial weight according to

[0003]

[Problems to be solved by the device]

 However, according to the conventional flywheel configuration of the internal combustion engine described above, a flywheel having a large inertial force is required in order to suppress the rotational fluctuation of the internal combustion engine at the time of idling when the vehicle is not running, for example. When a large driving force is required during driving, especially when accelerating, the inertial weight is not transmitted as the driving force and becomes a loss force, which reduces the power performance of the vehicle and the fuel consumption of the internal combustion engine. The problem is that it gets worse.

Therefore, in the present invention, it is necessary to solve the problem of improving the performance of the internal combustion engine by varying the weight of the flywheel attached to the output part of the internal combustion engine according to the state of the vehicle and the internal combustion engine. It is a specific subject.

[Means for Solving the Problems]

 A technical means for solving the above-mentioned problems is to provide a variable capacity flywheel, which is attached to an output portion of an internal combustion engine to stabilize a rotational fluctuation of the internal combustion engine, and a variable weight flywheel. And a control unit for changing the weight of the vehicle according to the state of the vehicle and the internal combustion engine.

[0006]

[Action]

 According to the variable displacement flywheel having the above structure, the control unit controls the weight of the variable weight flywheel attached to the output part of the internal combustion engine by the rotation of the internal combustion engine during idling when the vehicle is not running, for example. The control is performed to make it heavier in order to suppress fluctuations, while it is controlled to be lighter when a large driving force is required during running, especially during acceleration.

【Example】

 FIG. 1 shows an electromagnetic clutch type flywheel (weight variable flywheel) 3 mounted on a clutch cover-2 of a manual transmission clutch 1 of a vehicle built in a clutch housing CH, and the electromagnetic clutch type flywheel 3 is attached to the clutch cover-2. FIG. 3 is a cross-sectional view showing the configuration of a variable capacity flywheel that functions to enhance the stability of the engine by operating it according to the state of the internal combustion engine (engine). In the variable capacity flywheel, the drive plate 5 which receives the rotational force from the engine crankshaft 4 serves as a conventional flywheel. The rotational force from the engine crankshaft 4 received by the drive plate 5 is transmitted to the transmission main drive shaft 7 via the clutch disc 6.

The electromagnetic clutch coil 3A of the electromagnetic clutch type flywheel 3 rotates in the same manner as the drive plate 5 when an electric signal from the outside is applied. Therefore, the variable capacity flywheel becomes the total weight of the drive plate 5 and the electromagnetic clutch type flywheel 3 as a conventional flywheel, and the rotation fluctuation of the engine is caused when the vehicle is idling, for example. Suppress and stabilize engine operation. On the other hand, when an electric signal is not applied to the electromagnetic clutch coil 3A of the electromagnetic clutch flywheel 3, the electromagnetic clutch flywheel 3 is separated from the drive plate 5, so that the rotational force of the engine is the electromagnetic clutch. Regardless of the type flywheel 3, it is transmitted to the transmission main drive shaft 7 as it is, and a larger driving force is obtained.

FIG. 2 shows a microcomputer for controlling the variable capacity flywheel by outputting or interrupting the electric signal to or from the electromagnetic clutch coil 3A of the electromagnetic clutch type flywheel 3. The control circuit having the control unit 10 as a center is shown. As shown in FIG. 2, the output side of the control unit 10 is electrically connected to the electromagnetic clutch coil 3A of the electromagnetic clutch type flywheel 3. On the other hand, on the input side of the control unit 10, a vehicle speed sensor 12 which detects the vehicle speed of the vehicle 11 and outputs a vehicle speed signal, and a temperature of cooling water of the engine 13 which outputs an engine cooling water temperature signal. An engine cooling water temperature sensor 14, a throttle opening sensor 15 that detects the throttle opening of the engine 13 and outputs a throttle opening signal, and an engine speed that detects the engine speed and outputs an engine speed signal. A sensor 16, a clutch switch sensor 17 that detects the clutch switch state of the manual clutch of the vehicle 11 and outputs a clutch switch signal, and a gear position sensor 18 that detects the gear position of the transmission and outputs a gear position signal. Are electrically connected.

In the control circuit configured as described above, the control unit 10 includes the vehicle 11 and the engine 13 based on the signals output from the sensors 12, 14, 15, 16, 17, and 18 described above. The state of the variable capacity flywheel is controlled by determining the above state and outputting the electric signal to the electromagnetic clutch coil 3A of the electromagnetic clutch type flywheel 3 based on the determined state. That is, the operating condition of the vehicle 11 and the performance of the engine 13 can be improved by changing the weight of the inertial body of the variable capacity flywheel.
