Abstract
A linear actuator comprising a shaft and a nut in engagement with the shaft such that the nut translates within a linear range of motion axially on a center axis relative to the shaft in response to relative rotation between the nut and the shaft, a stop positioned at a travel limiting position and having a rotational input portion and an axial output portion, the rotational input portion configured to rotate about the center axis relative to the shaft, the axial output portion constrained from rotating about the center axis relative to the shaft and configured to translate axially on the center axis relative to the rotational input portion in response to relative rotation between the axial output portion and the rotational input portion, and an axially compliant member configured to bias the axial output portion towards the travel limiting position.
