Embodiment Construction

[0084] refer to figure 1 , shows an exemplary embodiment of an elastic return device 800 according to the first aspect of the invention. Such elastic return means 800 are configured to be able to generate an opposing force against the piston 105, 205 placed to move by the actuation system 300 of the clutch 100, 200 of the clutch mechanism. To this end, the elastic return means 800 includes:

[0085] - a first ring 810A designed to bear against the bearing surface of the clutch mechanism;

[0086] - the second ring 820A designed to bear against the piston 105, 205 of the clutch mechanism;

[0087] - A plurality of elastic elements 830A extending between the first annular member 810A and the second annular member 820A. exist figure 1 In the example shown, the plurality of elastic elements 830A are of the helical spring type distributed at regular angles with respect to the axis of symmetry S of the elastic return means 800 .

[0088]In particular, the second annular member ...

Abstract

The invention relates to an elastic return device including a gasket and a clutch mechanism (10) whose actuating system (300) includes a control chamber (750) designed to receive a pressurized fluid,a piston (105) which is axially movable in the control chamber (750) so as to engage or disengage the corresponding clutch (100), a balancing chamber (700) situated opposite the control chamber (750)in relation to the piston (105), and an elastic return device (800) housed in the balancing chamber and designed to exert an axial force against the piston (105). According to the invention, the elastic return device (800) includes, on one of its faces bearing against the piston, an internal peripheral end which extends radially beneath the piston (105) and which carries a gasket in order to sealoff the balancing chamber (700) from the control chamber (750). The invention likewise relates to a transmission system (1) including such a dual clutch mechanism (10).

Description

technical field [0001] The invention relates to an elastic return device capable of generating a force opposing an element enabling the engagement or disengagement of a clutch such as wet clutch mechanisms used in the automotive sector. The invention also relates to a clutch mechanism comprising such an elastic return device, and a transmission system integrating such a clutch mechanism. Background technique [0002] Clutch mechanisms are known which comprise a clutch rotating around an axis of rotation and a force generator designed to configure the clutch into a so-called disengaged or engaged configuration by means of a movable member called a piston, so that the The force generated in the area of ​​the clutch is transmitted to the clutch. [0003] As is known, the actuation system can be formed by a hydraulic pressure generator comprising (i) a control chamber designed to receive pressurized fluid, (ii) a piston, which is axially movable in the control chamber and exte...
