A frame type landing gear comprises a frame; the frame is connected with a force bearing strut; at least two wheel axles are arranged on the frame; and an airplane wheel is mounted on each wheel axle.The frame type landing gear further comprises an automatic sliding device, wherein the automatic sliding device comprises a driving mechanism and a clutch mechanism, wherein the driving mechanism isfixedly mounted on the frame and comprises a first output shaft and a second output shaft, wherein the first output shaft and the second output shaft can synchronously move; first and second transmission mechanisms are correspondingly connected to the first and second output shafts so as to transmit output rotation to the first and second airplane wheels; and the clutch mechanism is used for enabling the first transmission mechanism and the second transmission mechanism to be able to move between a first position and a second position so that the first transmission mechanism and the second transmission mechanism are linked with or separated from the first airplane wheel and the second airplane wheel. In the structure of the frame type landing gear, by using an improved automatic sliding device structure, the automatic sliding operation of the frame type landing gear is realized. The invention further discloses an aircraft including the frame type landing gear.
