摘要： Disclosed is a plastic composite including a magnetic alloy material in an amount of about 20 % by volume or greater on the basis of the total volume of the plastic composite. Accordingly, weight of the clutch may be reduced by about 0.4 kg and weight of the pulley can be reduced by about 0.4 kg with the result that overall weight may be reduced by about 0.8 kg.

摘要： An electromagnetic connection device includes an armature (4), a rotor (3), an electromagnetic coil (14), and a spring member (24) that biases the armature (4) in a direction in which the armature (4) is separated from the rotor (3). The electromagnetic connection device includes a damping member (25) mounted on the armature (4) so as to face the rotor (3). The armature (4) includes a flat portion (22) and a tubular portion (8). The damping member (25) includes a damper cover (26) including an abutment portion along the flat portion (22) and an engaging portion along the tubular portion (8), and an elastic member (27) sandwiched between the abutment portion and the flat portion (22). The damper cover (26) is put on the armature (4) from the side of the rotor (3) and movably held on the tubular portion (8). The flat portion (22) includes a concave portion (35) configured to store the abutment portion of the damper cover (26). There is provided an electromagnetic connection device capable of obtaining a high damping effect and raising the productivity while preventing the elastic member from being exposed to a friction surface.

摘要： An electromagnetic clutch includes an armature to be attracted to a rotor, an armature hub formed on one end portion of a rotating shaft, and a leaf spring which connects the armature to the armature hub and biases the armature away from the rotor. The leaf spring includes a base fixed to the armature hub, a stopper connected to the base, and a connecting piece surrounding the stopper by projecting outside from the base, and fixed to the armature. A through hole into which a rivet for fixing the base to the armature hub is inserted is formed in the base. A low-strength portion having strength lower than that in the periphery of the through hole is formed in a boundary portion between the base and a connecting portion.

摘要： A rotation transmission device is provided in which a collision sound by an armature and a rotor is less likely to occur, and further the armature is stably attracted to the rotor. A buffer (50) is provided between the armature (30) and the rotor (31). The buffer (50) is constituted by a metal annulus (51) axially movably supported by the armature (30), and a rubber annulus (52) configured such that as the armature (30) approaches the rotor (31), the rubber annulus (52) is axially compressed by the metal annulus (51) and the armature (30). The rubber annulus (52) has different axial thicknesses at different circumferential locations thereof such that when the degree of axial compression of the rubber annulus (52) is large, the rubber annulus (52) is axially compressed in its longer circumferential area than when the degree of axial compression of the rubber annulus (52) is small.

摘要： A drive plate of an electromagnetic-fan clutch. A body of the drive plate is provided with magnetic-insulation air holes (103, 103a, 103b), connection ribs (104, 104a, 104b), and magnetic conductive layers. The magnetic-insulation air holes (103, 103a, 103b) and the magnetic conductive layers are arranged alternatively along a radial direction of the body of the drive plate. A friction-increasing groove (105) is opened on the magnetic conductive layer. The thickness of the magnetic-insulation air holes (103, 103a, 103b) and the thickness of the connection ribs (104, 104a, 104b) are less than the thickness of the magnetic conductive layers. Six connection ribs (104, 104a, 104b) are distributed uniformly between the magnetic conductive layers, and the connection ribs (104, 104a, 104b) at two sides of the magnetic conductive layer are distributed along the radial direction of the body of the drive plate at an interval of 30 degrees. A drive plate through hole (101) is opened in the body of the drive plate, and accommodation walls (107, 107a) are disposed on the magnetic conductive layers. The drive plate is made of an SPHE steel plate or SPHD steel plate, implements magnetic insulation effect of a solid magnetic insulation layer by using the magnetic-insulation air holes, reduces the weight of the plate body, and improves the transmission efficiency. The disposition of the connection ribs and the grooves on end surfaces satisfies the rigidity of the plate body while ensuring the friction effect of the end faces as friction surfaces. In addition, also disclosed are a method and mould for manufacturing the drive plate of the electromagnetic-fan clutch.

摘要： An electromagnetic clutch includes a rotation transmission member supported by an input shaft portion via a bearing. The rotation transmission member includes a movement regulating portion having abutment portions that abut against the bearing. The clutch further includes first and second spring members that bias an armature toward a braking member, and a connecting member overlaid on the movement regulating portion. The connecting member has first holes at portions facing the abutment portions, and second holes at portions facing regions between the abutment portions. One-end portions of the first and second spring members are attached to the armature. First fixing members inserted into the first holes fix the other-end portions of the first spring members to the connecting member. Second fixing members inserted into the second holes fix the other-end portions of the second spring members to the connecting member and fix the connecting member to the movement regulating portion.

摘要： A rotation transmission device includes a control retainer (16A) and a rotary retainer (16B) having bars (22 and 26) arranged circumferentially alternating with each other such that pockets (27) are defined between the adjacent pairs of bars (22 and 26). A pair of rollers (15) are mounted in each pocket (27) with an elastic member (20) disposed between the pair of rollers (15) such that the pair of rollers (15) are pushed by the respective bars (22 and 26) to their respective disengaged positions when the control retainer (16A) and the rotary retainer (16B) rotate relative to each other. A spring holder (33) is fitted on an input shaft (1) while abutting one axial end surface of an inner ring (13). The spring holder (33) has spring support pieces (37) provided on the outer periphery thereof and preventing radially outward movement of the elastic members (20). The spring support pieces (37) are plate-shaped members disposed radially outwardly of the elastic members to extend in the axial direction in parallel to the outer periphery of the inner ring (13).
