Embodiment Construction

[0028] figure 1 A diagram or a Cartesian coordinate system is shown, in which the separating force in Newtons is plotted on the ordinate and the values ​​of the restoring system 1 , not shown here, are plotted on the abscissa. Separation stroke in millimeters. A first characteristic curve 15 shown with a dashed line shows the disengagement force characteristic curve of friction clutch 2 , not shown here, without compensating spring 5 and smoothing spring 7 . A second characteristic curve 16 shown with a dotted line shows the disengagement force characteristic curve of a friction clutch 2 , not shown here, with compensating spring 5 but without smoothing spring 7 . It can be seen here that the second characteristic curve 16 has a “bump” between the operating point 10 and the disengagement point 11 of the restoring system 1 , not shown here, which is negatively affected by the user of the restoring system 1 . aware. The characteristic curve 9 shows the disengagement force cha...

Abstract

Disclosed is an engagement / disengagement system for a friction clutch, comprising an engagement spring for generating an engagement force on friction plates of the friction clutch, a compensation spring for generating a compensation force acting in the direction opposite the engagement force, and a smoothing spring having a progressive load-deflection curve; the smoothing spring is connected in series to the compensation spring so that a characteristic curve of a resulting force has no more than one point of inflection between an operating point of the engagement / disengagement system and a disengagement point of the engagement / disengagement system.

Description

technical field [0001] The invention relates to a return system for a friction clutch for engaging and disengaging the friction clutch. Background technique [0002] Friction clutches are known in the prior art, in which disc springs provide the necessary pressing force between the friction elements so that sufficient torque can be transmitted via the friction elements. As the magnitude of the required torque increases, so do the demands placed on such disk springs. This means that the friction elements have to be pressed against each other with greater force. As a result, it is more difficult or at least less comfortable for the user of the friction clutch to actuate the disc spring because the disengagement force is greater. Furthermore, in the transition region from the disengaged state to the fully engaged state (operating point of the friction clutch), the forces acting on the friction elements of the friction clutch are significantly greater at high torques to be tra...
