COUNTER-ROTATING MOTORS WITH LINEAR OUTPUT

摘要

An actuator (100) includes a first rotary motor (102), a second rotary motor (104), and a transmission coupled to the first and second rotary motors. The transmission converts rotation of the first rotary motor (102) in a first direction and simultaneous rotation of the second rotary motor (104) in a second direction to linear motion of an output shaft (120) in a single direction The actuator is usable in an active automobile suspension.
