Automated RV landing gear

摘要

An automated landing gear for an RV with a dual action mechanism that allows an automatic extension tube and attached ground engaging foot to fully extend and retract in telescoping fashion within and out the bottom of an open ended outer tube mounted to an RV. A reversible motor rotates a vertical jack screw which engages a threaded jack nut to extend and retract an open ended inner tube out the bottom of the outer tube. The jack screw extends through a bearing and has a drive nut on its lower end. The drive nut is slidably encased by a drive tube that rotates in conjunction with the jack screw. Male threads on a lower end of the drive tube engage female threads within the automatic extension tube causing the automatic extension tube to extend and retract.
