摘要： A clutch (140) (e.g. multiple disc) includes a pilot magneto-rheological operator (174,198) which controls operation of an associated ball ramp operator (142,150,152) which, in turn, compresses a clutch pack (222A,222B) to selectively transfer torque between and input member (60) and an output member (244). The pilot operator includes an electromagnetic coil (174) disposed proximate a magneto-rheological fluid (198) contained within a chamber of a pilot clutch (160). Activation of the electromagnetic coil (174) creates a magnetic flux which travels through the magneto-rheological fluid (198) and couples the fluid clutch members, creating drag and relative rotation between members of the ball ramp operator (142,150,152). Such relative rotation of the ball ramp operator (142,150,152) selectively compresses the clutch pack (222A,222B) and transfer torque from the input member (60) to the output member (244).

摘要： An electrorheological fluid torque transmission and conversion system provides for variable control of torque in clutch and brake applications. Communication of mechanical energy between the drive elements (30,18) is accomplished by magnetic coupling to eliminate the need for a dynamic fluid seal for interface of moving parts to the interior portion of the electrorheological fluid containment chamber (16). Permanent magnets (44,46) are associated respectively with each of a first member (36) and a second member (38) which are magnetically coupled through a surface (34) with low magnetic permeability such that the first member (36) and second members rotate (38) in unison. A variety of permanent arrangemnets may be utilized. Further, the drive element (42) internal to the electrorheological fluid chamber (16) may be both mechanically and electrically decoupled. A floating electrode may be capacitively coupled through the fluid to the power supply. Inner and outer conductive plates (56,58) are provided for increased fluid surface contact area. Spacing between the inner and outer plates (56,58) is determined by the thickness of inner and outer ring members (60,62) therebetween, which may be easily removed and replaced for simplified assembly and adjustment. Condition responsive control of the electrorheological fluid torque transmission and conversion system is provided by closed-loop feedback of a signal indicative of rotational speed between the drive elements to the control system. The control system (12) may also incorporate internal power generation (80) to provide a self-contained system which does not require an external power source.

摘要： The present disclosure is a high-stability and large-torque magnetorheological fluid clutch. Firstly, in order to prevent sedimentation of the magnetorheological fluid, blades are installed on the disc body of an input disc. When the clutch operates in a power interruption mode, the blades can stir the magnetorheological fluid, so that the sedimented magnetorheological fluid is uniformly mixed. Secondly, in order to improve the maximum transmission torque of the magnetorheological fluid clutch, an excitation magnetic field is increased in a mode that a permanent magnet and an electromagnet are connected in series. Meanwhile, a third electric push rod is used for pushing the input disc, and the magnetorheological fluid works in a shearing-extruding working mode, so that the yield stress of the magnetorheological fluid is improved. Therefore, the maximum transmission torque of the magnetorheological fluid clutch is improved.

摘要： Systems and methods relating to a clutch system for use in controllably transmitting torque from an input shaft to an output shaft. The clutch system has a torque transmission fluid that has a viscosity that changes based on the strength of an electromagnetic field passing through the fluid. A number of sensors are placed at different radial locations on the torque transmission disks to detect the strength of the electromagnetic field. Based on the strength of the electromagnetic field, the amount of torque being transmitted from the input shaft to the output shaft can be adjusted. Also disclosed is a distributed actuation architecture that uses this clutch system. The distributed actuation architecture allows for the use of a single drive motor in conjunction with multiple instances of the clutch system to actuate a mechanical linkage, such as a robotic arm.

摘要： Disclosed is a magnetorheological clutch comprising a stationary part (1), a rotating primary part (2) with primary lamellae (7), and a coaxially rotating secondary part (3) with secondary lamellae (20). An adjustable magnetic field acts upon the magnetorheological fluid. In order to be able to transmit the greatest possible torque in a minimum of space and at minimal power consumption, at least one magnet coil (25) encompassing a first yoke (24a, 24b) is disposed such that primary lamellae (7, 7′) and secondary lamellae (20, 20′) are located on both sides thereof. The lamellae are made of a material which is provided with moderate magnetic permeability and allows limited short-circuit flux. A second yoke (27, 27′) having a face (32, 32′) that extends parallel to the lamellae adjoins the outermost lamella on both sides, “outermost” being in relation to the axial direction.
