Abstract

The invention relates to an operating assist device for vehicle clutch comprising: a movable component movable synchronously with an operating element; a rotatable component; an auxiliary elastic member applying a pushing force to rotate the rotatable component; a cam component capable of being arranged between the movable component and the rotatable component, used for transmitting the pushing force applied to the rotatable component to the movable component, wherein when the operating element is operated in a direction of disengaging a friction clutch, the auxiliary elastic member urges themovable component in the direction of disengaging the friction clutch, while the operating element is shifted from a disengage start position, where the operating element receives the reactive force of the clutch spring, to a disengage position where the disengagement of the friction clutch is completed.

Description

[0001] This application is a divisional application of the Chinese patent application with the application number 200610003655.X, the application date is January 9, 2006, and the invention title is "clutch operation booster device and vehicle equipped with the device". technical field [0002] The present invention relates to a clutch operation boosting device capable of reducing the force required to operate a friction clutch to break torque transmission of the friction clutch, and a vehicle equipped with the clutch operation boosting device. Background technique [0003] For example, a motorcycle's engine is equipped with a friction clutch that connects and disconnects torque transmission from the crankshaft to the gearbox. The friction clutch has friction plates and clutch plates arranged alternately with one another. The friction plate is constantly pressed against the clutch plate by the clutch spring, and maintains a state capable of transmitting torque. [0004] The ...
