摘要： A coupling device has two components which are rotatable relative to one another, a recess which is provided on the first component, and a locking element which is held movably on the second component and is movable relative to the components between a locking position in which the locking element engages in the recess and a release position in which engagement of the locking element in the recess is prevented. An actuating device is provided which is displaceable relative to the components and relative to the locking element and which has an actuating element formed from a first material, by which a movement of the locking element out of one of the positions into the other position can be effected by displacement of the actuating device. The actuating device has a main body which is formed from a second material which is different from the first material.

摘要： A pawl clutch may include a first member having at least one notch, and a second member. The first member and the second member may be configured to rotate relative to each other at a speed differential when the pawl clutch is disengaged. The pawl clutch may further comprise at least one pawl moveably retained to the second member and configured to engage the pawl clutch by engaging the notch of the first member. The notch of the first member may have one of a chamfered edge and a concave edge.

摘要： An electro-mechanical clutch apparatus includes a stationary member (22,122) having a center portion extending along an axis A and a stationary coil assembly (34,134) fixed about the center portion. A rotatable member (46,146) extends along the axis A and includes an annular projection (52,152) radially spaced from the coil assembly. A ratchet surface (29,129) presents a plurality of teeth disposed in axially aligned and radially spaced relationship with the annular projection. The rotatable member includes a magnetic pole piece (62,162) disposed in radially spaced and concentrically aligned relationship with said coil assembly. The rotatable member includes a locking member (58,158) pivotably attached to the annular projection and pivotable between an engaged position in engagement with one of the teeth in response to the coil assembly being de-energized and a released position displaced from engagement with the teeth and attracted towards the magnetic pole piece in response to the coil assembly being energized.

摘要： A selectable one-way clutch includes: a pocket plate including accommodating recess portions; a notch plate including engaging recess portions; a plate-shaped engaging piece; and a selector plate configured to switch between: a state in which the engaging piece rises toward the notch plate; and a state in which the engaging piece is accommodated in the accommodating recess portion. The notch plate includes a plane portion including a first inclined surface, and the first inclined surface provides the engaging piece with force in a direction into which the engaging piece is urged away from the notch plate, when the notch plate is rotated in an engaging direction into which the engaging piece rising toward the notch plate is engaged with the engaging recess portion, and one end portion of the engaging piece rises toward the notch plate and comes in contact with the plane portion.

摘要： A multi-mode clutch system (10) may include a cam slider (66) operatively associated with an actuator (82). A first cam profile (70) and a second cam profile may both be operatively associated with the cam slider (66). A first pawl (26) may be operatively associated with the first cam profile (70) and a second pawl may be operatively associated with the second cam profile (74) wherein the first cam profile (70) selectively acts on the first pawl (26), the second cam profile (74) selectively acts on the second pawl (30), and the multi-mode clutch system (10) is configured to allow multiple modes of operation between the first and second pawls (26, 30) and an inner race (14) according to different actuator (82) positions.

摘要： A structure of a ratchet type one-way clutch that enables a reduction of the installation space along the direction of the center axis and high torque setting. The structure includes a securing member arranged on the center axis of a ratchet type one-way clutch and having a holding portion opposed to the ratchet type one-way clutch in the axial direction. The outer race of the ratchet type one-way clutch is provided with a first fit portion including a plurality of through holes. The holding portion is provided with a second fit portion including a plurality of projections that is in fitting engagement with the first fit portions, respectively.

摘要： Overrunning coupling and control assembly and control system for use therein are provided. The system includes a control member mounted for controlled shifting movement between the coupling faces of first of second coupling members. A one-way locking member such as a detent is pivotally connected to the control member via a selector arm for movement between a disengaged position in which the control member is permitted to shift or rotate relative to the second coupling member and an engaged position between the control member and a locking member engaging portion of the second coupling member to lock the control member and the second coupling member together to prevent the control member from inadvertently shifting in a first direction relative to the second coupling member in the absence of an actuator command signal received by a bi-directional actuator subassembly including the selector arm connected to the control member.

摘要： A clutch system of the present invention executes, when switching a selectable one-way clutch from a lock mode to a free mode, an early mode switching control where while a selector plate is made go into a waiting state that a pawl member protruding from a fixed plate is abutting against a non-formation portion, a negative torque is made to act on a rotational plate in a negative rotational direction, and, by controlling the negative torque, the selector plate of the waiting state is made to rotate up to a release position.
