CLUTCH CONTROL DEVICE

PURPOSE:To facilitate countermeasure against abrasion of a clutch plate and attachment process of a device by driving the hydraulic piston of a master cylinder by the use of an electric driving means and providing a compensator which offsets clutch reaction by acting on the hydraulic piston. CONSTITUTION:The pinion 19 of an electric driving device 12 which is formed of an electric motor 13 and a gearing 14 is engaged with a rack part 20 which is formed in a hydraulic piston 4. And a compensator 21 is formed of a spring 23 and a lever 22 fixed on the rotating and moving shaft 18 of the gearing 14, and an elastic force for offsetting a clutch reaction is acted on a hydraulic piston 4. The hydraulic piston 4 is moved from the top dead point A to the direction toward the bottom dead point B and the oil pressure of an oil pressure chamber 6 is lowered when a motor 13 is driven thereat, and when the piston 4 moves further oil is supplied in the oil pressure chamber 6 from an oil tank 8 and the hydraulic piston 4 is moved down the bottom dead point B to be connected to a clutch. Accordingly, a clutch plate is easily protected from being worn and a device is easily attached.
