DEPLOYABLE AND RETRACTABLE SHOCK STRUT

A shock strut for a vehicle includes a housing with a through channel and a motor mount, and a motor fixed to the housing. The cylinder of a shock strut is configured to define a lead screw on its outer surface. The cylinder extends through the housing. The piston of the shock strut is attached to a ground engaging assembly. A gear nut rotatably mounted in the housing threadably engages the threaded cylinder, and is configured to be driven by the motor. The housing is attached to the vehicle, and the gear nut is controllably rotated to extend and retract the shock strut. A sensor provided on the assembly monitors the position of the shock strut. A torsion link assembly reacts rotational forces on the cylinder. 种用于载具的减震支柱，其包括具有贯通通道和马达底座的壳体以及固定到壳体的马达。减震支柱的缸体配置为在其外表面上限定丝杠。缸体延伸穿过壳体。减震支柱的活塞附接到地面接合组件。可旋转地安装在壳体中的齿轮螺母螺纹地接合螺纹缸体，并且配置为由马达驱动。壳体连接到载具上，并且齿轮螺母被可控地旋转以延伸和缩回减震支柱。设置在组件的传感器监测减震支柱的位置。扭力杆组件在缸体上产生旋转力。
