Title (EN) ROTATING ELECTRICAL WEDGE TORQUE TRANSMITTING DEVICE
(FR) DISPOSITIF DE TRANSMISSION DE COUPLE À CALE ÉLECTRIQUE ROTATIVE
Abstract:
(EN) A torque transmitting device (10) includes a clutch housing (14) rotatable about an axis (A), a first set of clutch plates (20A) splined to the clutch housing (14), and a second set of clutch plates (20B) interleaved with the first set and rotatable about the axis (A) of rotation. A push plate assembly (28) is splined to the clutch housing (14) for rotation therewith. A roller assembly (42) includes a roller housing (48) splined to the clutch housing (14), a roller supporter (54) housed in the roller housing (48), and a roller element (62) supported by the roller supporter (54). A wedge assembly (12) includes a wedge housing (64) connected to a wedge block (24). The wedge housing (64) includes a ramp member (70) defining a ramp surface (16) with the roller element (62) contacting the ramp surface (16). A motion converter (71) is disposed between the push plate assembly (28) and the wedge housing (64) such that axial movement of the push plate assembly (28) causes rotation of the wedge assembly (12) relative to the roller assembly (42).
(FR) L'invention concerne un dispositif de transmission de couple (10), lequel dispositif comprend un carter d'embrayage (14) pouvant tourner autour d'un axe (A), un premier ensemble de plaques d'embrayage (20A) cannelées sur le carter d'embrayage (14), et un second ensemble de plaques d'embrayage (20B) entremêlé avec le premier ensemble et pouvant tourner autour de l'axe (A) de rotation. Un ensemble plaque de poussée (28) est cannelé sur le carter d'embrayage (14) pour tourner avec ce dernier. Un ensemble rouleau (42) comprend un boîtier de rouleau (48) cannelé sur le carter d'embrayage (14), un élément de support de rouleau (54) contenu dans le boîtier de rouleau (48), et un élément de rouleau (62) supporté par l'élément de support de rouleau (54). Un ensemble de cale (12) comprend un boîtier de cale (64) relié à un bloc de cale (24). Le boîtier de cale (64) comprend un élément de rampe (70) délimitant une surface de rampe (16), l'élément de rouleau (62) venant en contact avec la surface de rampe (16). Un convertisseur de mouvement (71) est disposé entre l'ensemble plaque de poussée (28) et le boîtier de cale (64), de telle sorte qu'un mouvement axial de l'ensemble plaque de poussée (28) provoque la rotation de l'ensemble de cale (12) par rapport à l'ensemble de rouleau (42).
