摘要： A torsional damping mechanism (22) adapted to be disposed between an engine (10) and a transmission (12) operative to drive ground wheels (16) of a vehicle. The mechanism includes a viscous damping device (30), an idle rattle assembly (32), a torque transmitting torsion spring bar (28) disposed in series with the idle rattle assembly and in parallel with the viscous damping device, and a mechanical friction assembly for connecting the mechanism to the engine. Mechanism (22) is structurally configured to have a low inertia. The viscous damping device includes lost motion means (48k, 50c) which allows attenuation of low amplitude torsionals without damping.

摘要： An improved differential gear mechanism is disclosed of the type including a clutch pack (35) operable to limit differentiating action of a pair of side gears (23,25) relative to a differential case (11). The clutch pack (35) is engaged by a cam means (41) including a pair of cam members (23,43) having engaging cam surfaces (45,47). Initiation of engagement of the clutch pack (35) may occur in response to an external signal (83) by means of a pair of actuation members (53) which engage one of the cam members (43). The actuation members include terminal portions (57) which extend to the exterior of the gear case and engage a cam surface (77;101) of an actuating cam member (71;91). The actuating cam member has an outer peripheral retarding surface (79) which may be engaged by a plunger (85;113) of an electromagnetic actuator (81;107) in response to the external signal (83). Engagement of the retarding surface (79) by the plunger causes ramping of the terminal portions (57) on the cam surface, and resulting axial movement of the actuation members (53), thus initiating ramping of the cam means (41) and engagement of the clutch pack (35), with relatively little axial force involved, and utilizing a differential structure which is modified only slightly from those now commercially available.

摘要： A modulating limited slip differential is disclosed of the type including a gear case (11; 111; 211) an actuating mechanism (51; 151; 251) being operable to apply a force to a clutch pack (41; 141; 241) to retard rotation between a side gear (25; 125; 225) and the gear case. The actuating mechanism includes an outer actuating plate (55; 155; 255) which normally rotates at the same speed as the gear case. The differential includes an electromagnetic actuator (81; 181; 281) which is operable to cause rotation of the outer actuating plate relative to the gear case resulting in ramping of a plurality of cam balls (79; 179; 279) and axial movement of an inner actuating plate (53; 153; 253) to load the clutch pack.

摘要： An electroviscous fan clutch (10) is employed as an accessory drive mechanism within a truck or automobile. A shaft (36), either driven by the engine or driving a load (31), carries a clutch member (14) arranged for fluid engagement with a body member (12) for the transmission of torque therebetween when electroviscous fluid is disposed in an operating chamber (45) defined by complimentary shear surfaces (40 and 44) in the clutch and body members. The clutch and body members are electrodes, connected to a source of high voltage potential (86), which establish an electrostatic field within the operating chamber to selectively vary the characteristic viscosity of fluid flowing therethrough.
