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： A magnetorheologic clutch includes a stationary part, a rotatable primary part having primary discs, a secondary part having secondary discs, and a chamber containing magnetorheologic fluid formed between the primary and secondary parts that is exposed to an adjustable magnetic field. To make a magnetorheologic clutch as small as possible which is capable of transmitting a peak torque at a minimum power consumption and which is easily controlled, at least one magnet coil is axially arranged before or after the discs and encompasses a first U-shaped cylinder head whose two surfaces are arranged on the side of the discs in a parallel thereto. A second cylinder head is disposed on the side of the discs opposite with respect to the first cylinder head. Areas of the secondary part are radially disposed inside and outside the discs which are made of a low-permeability magnetic material.
