Abstract
A clutch operating system includes a clutch pedal; a clutch master cylinder that generates hydraulic pressure by operation of the clutch pedal; a clutch release cylinder that operates the clutch by the hydraulic pressure; and a clutch fluid reservoir that stores fluid. The clutch master cylinder includes a cylinder with a wide section, an intermediate section, and a narrow section; a piston in the cylinder, with an intermediate section that fits in the intermediate cylinder section, and a narrow section that fits in the narrow cylinder section; a reservoir fluid line fluidly communicating the clutch fluid reservoir and the clutch master cylinder; an operating fluid line fluidly communicating the clutch release cylinder and the clutch master cylinder; a return spring providing a restoring force to the piston; and a piston rod that delivers movement of a clutch pedal to the piston.
