The invention specifically discloses a simple sleeve strut type undercarriage. The simple sleeve strut type undercarriage comprises a shock absorber and a retractable system, wherein the shock absorber comprises a shock absorber outer cylinder, a shock absorber inner cylinder, a torque arm and an airplane wheel; the folding and unfolding system comprises a folding and unfolding actuating cylinder, a walking beam, a trunnion connecting rod, a reaction connecting rod, a side supporting rod and a resistance rod; and wherein the upper end of the shock absorber outer cylinder is hinged to one end of the retractable actuating cylinder, one end of the walking beam, one end of the reaction connecting rod and one end of the resistance rod through the upper end of the trunnion connecting rod, and the lower end of the shock absorber outer cylinder is hinged to the lower end of the side supporting rod; one end of the shock absorber inner cylinder is slidably connected in the shock absorber outer cylinder, the other end of the shock absorber inner cylinder is fixedly installed at the upper end of an airplane wheel, and the shock absorber inner cylinder and the shock absorber outer cylinder are hinged through a torsion arm. According to the invention, folding and unfolding functions of the undercarriage can be realized, wherein the folding and unfolding functions of the undercarriage can be achieved by folding and unfolding the actuating cylinder, the lower locking mechanism, the upper locking mechanism, the side supporting rod and other mechanisms.
