Problems solved by technology

In fact, in the case of a dual clutch arrangement, simultaneous closing of both clutches is mechanically impossible, since the dual clutch allows alternate coupling of the engine shaft of the vehicle with two coaxial input shafts of different gearbox ratios. Compatible

Embodiment Construction

[0041] exist figure 1 A clutch device is shown above, which is identified by the numeral 10.

[0042] The clutch device 10 comprises a clutch comprising a diaphragm 12 which is pivotable between a rest position in which the clutch is disengaged and an active position in which the clutch is engaged. For example, the clutch is equipped with a double clutch unit.

[0043] When the diaphragm is in the active position, the diaphragm 12 tightly surrounds the friction plate, which is connected to the driven part in rotation, and is located between the pressure plate and the reaction plate, which are connected to the driving part in rotation.

[0044] When the diaphragm is in the rest position, the diaphragm 12 no longer tightly surrounds the friction plate between the pressure plate and the reaction plate. The friction disk is thus no longer rotationally connected to the pressure plate and the reaction plate.

[0045] A thrust should be applied to place the clutch in the active po...

Abstract

The device comprises a clutch comprising a diaphragm (12) toggling between a disengaged rest position and an engaged active position. It is returned to its rest position such that it has to be pushed in order to bring it into the active position. It also comprises an operating device (14) comprising: - an actuating member (16) that can be moved over a theoretical total travel between first and second positions. The diaphragm reaches its rest position when the actuating member is still some distance away from the first position; and - movement-assistance means (26) intended to apply an assistance force opposing a return force on the diaphragm (12). Over the theoretical total travel towards the first position, the assistance energy is greater than or equal to the return energy which means that the actuating member, in operation, always remains some distance away from the first position.

Description

technical field [0001] The invention relates to a clutch device, in particular for a motor vehicle, comprising a power booster group control device. Background technique [0002] In the prior art, in particular according to the control device known from patent document FR-A-2 896 288 for connection to a clutch of a motor vehicle, the clutch can be swiveled between a rest position and an active position, in the rest position In the active position the clutch is engaged and in the engaged position the clutch is disengaged. The clutch elastically returns to its rest position. [0003] The control device comprises an actuating member of the clutch, which is connected directly or indirectly (for example by means of a hydraulic circuit) to the clutch. The actuation member is movable between a position in which the clutch is in its rest position, and another position in which the actuation member and the clutch cooperate to maintain the clutch in the active position. [0004] Th...
