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： The present invention relates to a linear drive with a stator, a runner, and two rotative drive units provided for driving the runner. It is provided according to the invention that the linear drive comprises two magnetorheological clutches, wherein the first drive unit can be coupled to the runner using a first magnetorheological clutch and the second drive unit can be coupled to the runner using a second magnetorheological clutch. The output torque of the first drive unit acts upon the runner in the opposite direction to the output torque of the second drive unit.

摘要： A transmission apparatus has two components that move in translation relative to one another and a coupling gap between the components containing a magnetorheological medium. The gap is formed and sealed outwardly at first and second ends so that the magnetorheological medium remains in the coupling gap as a sort of controllable friction lining, irrespective of a coupling between the components, in accordance with the magnetic field applied in the coupling gap. One of the components has plurality of radially extending arms that carry a magnetic field generation device. Each magnetic field generation device has an electric coil with a least one winding extends completely beside the central axis and at a distance therefrom. Different poles of the magnetic field generation devices are provided at the adjacent ends of adjacent arms of a component. The coupling gap is connected to a reservoir of magnetorheological medium.
