Description

Clutch control device using damper method

According to the present invention, a damper composed of an oil return pipe, a control valve, and a piston is attached to a clutch release spoke connected to a clutch pedal as an auxiliary means, and a damper (Damper) is added to facilitate operation to smoothly clutch in response to an improper operation of a driver. It relates to a clutch control device using the) method.

In general, a clutch is installed between a flywheel and an input shaft of a transmission to transmit and block power of an engine transmitted to the transmission.

In other words, when starting the engine or shifting gears of the transmission, the engine is disconnected from the engine, and when the engine is started, the engine is gradually connected.

In the conventional clutch system, as shown in FIG. 3, the release spoke 24 and the release lever 25 operate the pressure plate 26 due to the displacement change in which the clutch pedal 21 is operated. The flywheel 27 controls the transmission input shaft 23 to control the flywheel 27 and controls the connection / disconnection using micro displacement in such a situation. There was a problem such as turning off the start or a shock of the connection occurs.

Accordingly, the present invention has been made to solve the above-mentioned problems. When the clutch pedal is operated, the clutch disc quickly cuts power transmission from the flywheel to the transmission input shaft, and the clutch pedal is released quickly even if the clutch pedal is released rapidly. By controlling the operation of the spokes to gradually transmit power to the transmission input shaft to provide a clutch control device that can prevent overload and starting of the engine of each vehicle due to the connection shock.

In order to provide the above clutch control device, the control valve is acted unidirectionally by using a damper whose load characteristics are controlled according to the degree of opening and closing of the control valve so that the clutch pedal displacement, the displacement of the relief spoke, the engine speed (RPM) and the transmission The piston rod of the damper consisting of the control valve, oil return pipe and piston is connected to the relief spoke in connection with the controller that receives the input and output speed (RPM) of the input and output side. It is to provide a device that transmits the power of the input shaft of the transmission.

Hereinafter, the structure and operation of the present invention will be described in connection with the accompanying drawings.

1 is a conceptual diagram for explaining the operating structure of the present invention, Figure 2 is an operating characteristic diagram of the clutch pedal and the release spoke according to the embodiment of the present invention.

When the clutch pedal 1 is actuated and released, the release spoke 2, the release bearing 3 and the release lever 4 are operated so that the pressure plate 5 intercepts the clutch disc 6 from the flywheel 7 In the clutch structure for transmitting and interrupting power to the transmission input shaft (8),

A damper (D) consisting of a control valve (10), an oil return pipe (11), and a piston (12) operated by a controller (9) is connected to the tip of the relief spoke (2) and the rod (13) of the piston (12); It is a structure made by connecting.

According to the present invention, the process of disconnecting the power from the engine operates the clutch pedal 1 so that the release spoke 2 and the lever 4 release the pressure plate 5 to release the clutch disc 6 from the flywheel 7. It is the same as the conventional method of cutting off the power to the transmission input shaft 8 by disengaging, and when the power is transmitted, if the clutch pedal 1 is released quickly, a connection shock is generated by the return spring. Only when the power is transmitted, the ignition can be turned off or the vehicle can be eliminated. However, in the present invention, the clutch pedal 1 input from the controller 9 can be removed even if the driver is poorly operated or accidentally released from the clutch pedal 1 by mistake. Of the damper (D) by controlling the opening and closing amount of the control valve 10 by detecting the displacement of the displacement, the displacement of the release spoke (2), the engine speed and the input / output speed of the transmission. The process is to minimize the connection shock of the clutch by the rod 13 of the piston 12 to optimally control the release spoke (2) by the load characteristics of the damper (D).

And as shown in Figure 2 when looking at the operating state of the clutch pedal 1 and the release spoke (2) according to the embodiment is as follows.

[table]

As described above, in the present invention, even after the clutch pedal 1 is released, the lily spoke 2 exhibits different operating characteristics (corresponding to section C).

Therefore, the present invention applies a damper having an additional device, that is, a load characteristic to the relief spoke, so that the clutch can be smoothly controlled even when the clutch pedal is rapidly released by a novice driver and a mistake in operation, so that the start-off and the vehicle's shock due to the connection shock of the clutch are prevented. In addition to minimizing wandering, the impact of connection to each engine of the vehicle is eliminated.
