FAILSAFE SMART BAR ACTUATOR

摘要

A failsafe actuator (102) for returning an actuator driven element (318) to a failsafe position in case of a failure condition is provided. The failsafe actuator may include mechanical (300) or electrical (500) means to provide a failsafe function. Such a failsafe actuator may be used in a stabilizer bar system (206) of a vehicle to ensure that at least one stabilizer bar (110a, 110b) is returned to a failsafe or engaged condition should a failure condition occur when the stabilizer bar is disengaged. Various failure conditions can include loss of electrical power to the actuator or some internal actuator failures.
