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 glide 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.

The invention concerns an apparatus comprising a piston fixed by circumferential tabs (26) to a transverse wall (11), the piston (20) or the wall (11) having through holes for fixing the tabs (26), said holes being finally closed by shutters. The invention is applicable to motor vehicles.
摘要:
A hydrokinetic coupling device having a transversely extending wall with a guide ring securely fastened thereto. A moveable piston is sealingly slidable along the guide ring and rotationally linked to the transverse wall while being moveable via tangential resilient blades secured to a driving member. The driving member is welded to the wall and the blades are attached to the piston by attachment members including a first member secured to the blades and a second member engaging the first member.
摘要:
A lock-up clutch for a fluid coupling has a rotating casing having a radial wall which is releasably coupled by the clutch to a piston. The wall is in a fixed axial position; the piston is arranged for relative axial displacement and is coupled to the wall by tongues. Fastening shanks extend through holes in the piston and holes through the ends of the tongues. A friction wedge is interposed between each tongue and the piston, thus preventing radial displacement of the tongue with respect to the piston after the piston has been secured on the fastening shanks (by means of fastening sleeves).

The power actuator comprises a housing in which are mounted a motor-driven worm gear and an actuating shaft for controlling the operative condition of a machine element. Rotary motion of the worm gear is transmitted to the actuating shaft by one or more gear wheels and a sector gear which is fixed for angular movement with the actuating shaft. The gear wheel meshes with the sector gear. A force moderating spring is disposed inside and is attached to the housing. The force moderating spring is attached to a link which extends alongside a portion of the sector gear and which is connected to the gear wheel for transmitting the spring force thereto.
