摘要:
A hydrokinetic coupling device includes a lock-up clutch having at least one friction disc mounted such that it can slide axially with respect to a first rotary shaft, at least one first backing disc rotating as one with a secondary rotary shaft and a support ring to support the backing disc. The support ring has at least one axial groove circumferentially delineated by an upstream face and by a downstream face. A radial guide tooth of each backing disc is housed such that it can slide axially in the groove. Elastic preload elements are provided which are able to exert a preload torque to clamp the guide tooth of each braking disc circumferentially against one of either the upstream or downstream faces of the guide groove.

摘要:
A locking clutch has a piston which is movably mounted axially in relation to a fixed wall and rotationally connected to the wall by tongues. For coupling the tongues to the piston, an attachment has a first portion, which is fixed to the side of the tongues that is opposite to the piston, and a second portion, which to engage the first portion, only requires attachment action on the side of the piston.
摘要:
A device for maintaining a clutch release bearing in contact with a clutch cover assembly at all times comprises a clutch release bearing operating shaft, a motorized actuator and coupling devices coupling the actuator to the shaft. These coupling devices incorporate a gear unit driven by the actuator and a toothed sector meshing with the gear unit and rotating freely on the shaft. The toothed sector cooperates with a lever fastened to the operating shaft through the intermediary of a thrust device which is implemented with play. An elastic device for presetting the force with which the clutch release bearing bears on the clutch cover assembly when the clutch is engaged, is disposed between the toothed sector and the lever and operates to increase the play of the thrust device.
