    摘要: A magnetorheological fluid clutch apparatus comprises an input rotor adapted to be coupled to a power input, the input rotor having a first set of at least one input shear surface, and a second set of at least one output shear surface. An output rotor is rotatably mounted about the input rotor for rotating about a common axis with the input rotor, the output rotor having a first set of at least one output shear surface, and a second set of at least one output shear surface, the first sets of the input rotor and the output rotor separated by at least a first annular space and forming a first transmission set, the second sets of the input rotor and the output rotor separated by at least a second annular space and forming a second transmission set. Magnetorheological fluid is in each of the annular spaces, the MR fluid configured to generate a variable amount of torque transmission between the sets of input rotor and output rotor when subjected to a magnetic field. A pair of electromagnets are configured to deliver a magnetic field through the MR fluid, the electromagnets configured to vary the strength of the magnetic field, whereby actuation of at least one of the pair of electromagnets results in torque transmission from the at least one input rotor to the output rotor.

    摘要: A torque transfer mechanism is provided for controlling the magnitude of a clutch engagement force exerted on a multi-plate clutch assembly that is operably disposed between a first rotary and a second rotary member. The torque transfer mechanism includes an actuator having a first segment fixed for rotation with the first rotary member and a second segment having a screw thread formed thereon which is rotatably and slidably disposed within a chamber filled with magnetorheological fluid. An electromagnetic coil is disposed in proximity to the chamber and is selectively energized for varying the viscosity of the magnetorheological fluid so as to induce axial movement of the actuator for engaging the multi-plate clutch assembly.

    摘要: A vehicle differential includes a case which is rotatably supported within an axle housing. The case is formed having a center wall which divides the interior of thereof into first and second fluid chambers. The ends of a pair of axle shafts extend into the case and respectively within the fluid chambers. Each of the fluid chambers is filled with a rheological fluid. Respective electromagnetic coils are disposed within or adjacent to each of the fluid chambers. An electronic controller is provided for supplying electrical current to each of the electromagnetic coils in response to sensed operating conditions of the vehicle, such as rotational speed and torque of the axle shafts. By varying the magnitude of the electrical current supplied to the electromagnetic coils, the strength of the magnetic field applied to the rheological fluid contained in each of fluid chambers can be varied. As a result, the resistance to flow or shear of the rheological fluid, which affects the amount of torque which is transmitted from the rotatably driven case to each of the axe shafts, can be varied in response to the operating conditions of the vehicle.
