Design of the clutch pedal and the torsion coil spring assist system

The present invention provides a method and a clutch pedal torsion coil spring assisted design system, the torsion spring clutch pedal assist system design method comprising: determining the geometrical principle of the torsional deformation of the spring 1 expression; torsional force analysis to establish the torsion spring spring biasing force Fn expression its mounting point B on the pedal 2; establishment of a torsion spring on the pedal arm pivot point O on its mounting biasing force Fn point B on the pedal in accordance with geometric principles Ln expression 3; expression 1, expression 2, expression 3 based on torque balance principle and equation 1 is determined, according to the established model expression torsion spring assisted 4; torsion spring assistance system according to the torsion spring 4 assisted design model expression clutch pedal. The clutch pedal torsion spring assist system design method, the conventional method corrects a torsion spring defined direction of force on the wrong problem pedal, the clutch pedal to avoid torsion spring assist system large errors.
