磁流变流体离合器设备和控制系统
摘要：
一种磁流变流体离合器设备，包括输入转子，适于耦接到动力输入件，输入转子具有第一组至少一个输入剪切面和第二组至少一个输出剪切面。输出转子可旋转地安装在输入转子周围，以围绕与输入转子的公共轴线旋转，输出转子具有第一组至少一个输出剪切面和第二组至少一个输出剪切面，输入转子和输出转子的第一组由至少第一环形空间隔开并形成第一传动组，输入转子和输出转子的第二组由至少第二环形空间隔开并形成第二传动组。磁流变流体位于每个环形空间中，MR流体配置为当经受磁场时在输入转子和输出转子的组之间产生可变量的扭矩传递。一对电磁铁配置为通过MR流体传递磁场，电磁铁配置为改变磁场的强度，由此驱动这对电磁铁中的至少一个使得扭矩从至少一个输入转子传递至输出转子。
摘要（英）：

In some embodiments, a rotorcraft flight control actuator includes a driving member configured to receive mechanical energy from a power source, a driven member, a magnetorheological (MR) fluid disposed between the driving member and the driven member and configured to transmit a variable amount of mechanical energy from the driving member to the driven member, an output member configured to be coupled between the driven member and a flight control device of a rotor system, and a magnetic circuit configured to deliver a magnetic field towards the MR fluid, the magnetic circuit configured to vary the strength of the magnetic field in response to inputs.
