Abstract

An electrorheological clutch comprises drive and driven members that selectively engage by the application of a voltage to an electroheological fluid (ER) provided between the driven and driven members. The drive and driven members are formed with axially-oriented surfaces that define between then axially-oriented spaces for the ER fluid so as to minimize problems with settlement of the ER particles.
