摘要： A method of controlling a pressure control valve assembly (69) to control a control pressure (43,71) in a system (11) including a source (47,49) of pressurized fluid. The control valve assembly is operable to vary the control pressure in response to variations in an electrical input signal (87) to an electromagnetic coil (81). The control valve assembly defines an inlet (77) in communication with the control pressure, an outlet (93) in communication with the low pressure, and a valve seat (89) disposed intermediate the inlet (77) and the outlet (93). A poppet valve member (91) is biased toward the valve seat by a biasing means including an armature (95), the biasing force being generally proportional to the input signal to the coil. The method comprises the steps of selecting a predetermined, minimum pressure for the control pressure corresponding to a minimum condition of the system. Next is selecting the biasing means to apply a biasing force to the poppet valve (91) corresponding to a fluid pressure less than the predetermined minimum pressure for the control pressure. The last step is selecting the electrical input signal (87) to correspond to the desired control pressure, an increasing input signal resulting in an increasing biasing force on the poppet valve member (91), but with no substantial movement thereof.

摘要： A differential assembly (20) including a rotatable casing (22) having an axis of rotation (23), a selectively energized electromagnet (44) proximal the casing, and a rotatable first clutch (54) disposed within the casing, the first clutch placed in operative engagement with the casing in response to the electromagnet being energized. Relative rotation between the first clutch and the casing is slowed by their being in operative engagement. A rotatable clutch hub (70) and a second clutch (76, 78) are disposed within the casing, and the casing and the clutch hub are rotatably coupled through engagement of the second clutch, which is operatively engaged in response to relative rotation between the first clutch and the casing being slowed. At least one rotatable pinion gear (106) is disposed within the casing and revolves about the axis of rotation. At least one side gear (94, 96) engaged with the pinion gear and rotatable about the axis of rotation is disposed within the casing, and is rotatably coupled to the casing through the second clutch during engagement of the second clutch. Neither of the first clutch and the second clutch is appreciably engaged with the casing in response to gear separating forces exerted between the pinion gear and the side gear.

摘要： An electronically controlled front wheel drive limited slip differential assembly that is designed to allow an operator to manually or automatically control the limited slip function. The differential control and actuation assembly is located external to the front transaxle (2) and differential case (1). The assembly includes an electric solenoid (5) that modulates hydraulic pressure produced by a gerotor pump (6). When the limited slip differential control is in the ON position, hydraulic pressure produced by the gerotor pump engages a friction clutch pack (8), which couples the differential case (1) to the front axle output shaft (9). When the limited slip function is in the OFF position, the electrical solenoid (5) does not allow the gerotor pump (6) to generate sufficient hydraulic pressure to actuate the clutch pack (8). When the differential control is in an intermediate position, the specific control setting, and the rotational speed of the front axle output shaft (9) relative to the rotational speed of the differential case (1) determine differential engagement. In addition to the ability to manually control the limited slip function, a computer processor/logic unit (13) can also electronically control the function.

摘要： An electromagnetic coupling apparatus interposed between a fixed housing (30) and a rotating member (22). The electromagnetic coupling apparatus includes a multiplate brake mechanism (74), a ringlike core member (90) fixed in the housing, an annular exciting coil (98) accomodated in an annular groove (96) of the core member, and a ringlike armature member (110) opposed to the annular groove of the core member. The armature member (110) has an outer diameter larger than the outer diameter of the core member. The electromagnetic brake further includes a cylindrical pressure member (120) having one end fixed to an outer circumferential portion of the armature member and the other end engaged with the multiplate brake mechanism. The cylindrical pressure member (120) surrounds the core member so as to be movable in a direction of applying a pressure to the multiplate brake mechanism as being guided by the core member. The opposed portion between the core member and the armature member is formed by tapered end surfaces (111,113) each having a predetermined tapered angle.

摘要： A differential (10) having a camming element (150) disposed between a first clutch (50) and a first side gear (24), the camming element has first (36) and second (152) camming portions coupling the camming element to each of the first clutch and first side gear, adapted to couple them together. An electromagnet (60) of variable strength urges the first clutch into engagement with an interior surface of the casing (12). Relative rotation between the camming element and the first side gear induces axial separation therebetween, urging a second clutch (101) attached to a second side gear (100) in abutting communication with the first side gear, into engagement with another interior surface of the casing. The axial force exerted on the second clutch by the camming element through the first and second side gears may be a fixed multiple of the axial force acting between the first clutch and the camming element.

摘要： A differential gear mechanism including a clutch assembly (35) for retarding rotation between a side gear (23) and a gear case (11,45), and a ball ramp actuator for actuating the clutch assembly. The ball ramp actuator includes an inner actuating plate (49) within the gear case, and an outer actuating plate (51) disposed external to the gear case. In order to initiate ramp up of the ball ramp device, an electromagnetic coil assembly (67) includes an annular coil (75) which is disposed in face-to-face relationship with the outer actuating plate (51). An annular drive plate (83) is disposed between the coil (75) and the outer actuating plate (51), and is drawn into frictional engagement with a layer of friction material (81) upon energization of the coil. The drive plate (83) is connected by pins (89) to be axially movable relative to the outer actuating plate, but fixed to rotate therewith, such that frictional engagement of the drive plate (83) retards rotation of the outer actuating plate (51).

摘要： The electromagnet positive clutch for interlocking connection between concentric drive shafts is slid, together with its enveloping external bushing (10), concentrically to a shaft (1) into a drive housing (2), whereby outside the bushing (10) in the region of the ring magnets (16) a gap which reduces stray flux is created and the sliding bushing (18), the armature disc (19) including the magnet (16) and any bearings (25) can be pre-mounted to ensure correct operation and protection from damage. A roller bearing (25) for the coupling part (24) carrying the counter toothing (22) on the other shaft can be provided at the outer end of the bushing (10). The low flux loss design and arrangement in the region of a seal space which in any case is present in the housing (2) permit operation with small couplings and, drive housings (2) of the same size, with or without inserted couplings as desired, can be used.

摘要： An electromagnetically locking clutch for motor vehicle differential gears with two concentrically-arranged annular coils (8, 21) integral with the housing one for a friction-type multiple disc clutch (14) and one for a positive-action claw-type clutch (26) arranged concentrically thereto. The two clutches (14, 26) connect a hub (2) with a bell-shaped element (3). The hub (2) and the bell-shaped element (3) are each linked with a connecting member of the differential to resist rotation. The multiple-disc clutch (140) is closed by a self-actuating system if a threshold value for a relative rotation speed is exceeded. The claw-type clutch (26) is closed arbitrarily and opened by self-actuation if a threshold value for an operating time is exceeded.
