F16D37/008 - CPC Classification

Classification description:

Clutches in which the drive is transmitted through a medium consisting of small particles, e.g. centrifugally speed-responsive the particles being carried by a fluid, to vary viscosity when subjected to electric change, i.e. electro-rheological or smart fluids
