Damping end-stop of electric braking apparatus

摘要

An electric braking apparatus is provided and includes an electromechanical actuator (EMA) configured to apply an axial load on a brake stack and a damping end-stop. The damping end-stop is configured to transmit torque into the EMA and includes an end cap, a screw disposed such that a longitudinal axis about which the screw is rotatable extends through the end cap, a nut threadably engaged with the screw and movable with the end cap relative to the screw with screw rotation and a spring element anchored on the end cap to resist the screw rotation beyond a predefined position.

1. An electric braking apparatus, comprising:
an electromechanical actuator (EMA) configured to apply an axial load on a brake stack; and a damping end-stop configured to transmit torque into the EMA and comprising: an end cap comprising first, second and third bosses; a screw disposed such that a longitudinal axis about which the screw is rotatable extends through the end cap; a nut threadably engaged with the screw and movable with the end cap relative to the screw with screw rotation; and a spring element anchored on the first boss, biased by the second boss to resist the screw rotation beyond a predefined position and pre-loaded by the third boss against the second boss.
