アクチュエータアッセンブリおよびクラッチアッセンブリ
Document Type and Number:
Japanese Patent JP6639730
Kind Code:
B2
Abstract:
An actuator assembly for being operated in the driveline of a motor vehicle comprises a drive unit for generating an operating force and a ramp unit drivable by the drive unit. The ramp unit comprises an abutment element, a first ring and a second ring. The first ring is drivable by the drive unit so as to rotate around a rotational axis (A) and a plurality of circumferentially distributed axial through-openings. In each of the axial through-openings two rollers are arranged of which respectively a first roller is axially supported against the abutment element and a second roller is axially supported against the second ring The second ring is configured to be held in a stationary component in a rotationally fixed and axially movable way and comprises a plurality of circumferentially distributed ramps which each cooperate with an associated roller. The ramps are configured such that rotatingly driving the rotatingly drivable first ring by the drive unit generates an axial movement of the second ring relative to the first ring. A clutch assembly can have such an actuator assembly.
