FIELD: transport.
SUBSTANCE: chassis contain a wheel assembly (trucks), a hydraulic shock absorber frame (bearing rod) for supporting the wheel assembly and retraction assembly, integrated with shock absorber frame. Wherein the retraction assembly includes a hinge pin strut integrated with the suspension frame and the fuselage to accommodate wheel assembly, shock strut frame and retraction assembly completely inside the fuselage in the retracted position. Retraction assembly comprises a retraction /chassis extension drive connected to the hinge pin strut to move the chassis from the extension position to a retracted position in which the retraction / extension drive connects the pivot points on the struts of the hinge pin and on the shock frame.
EFFECT: invention provides stability of chassis and prevents wagging the aircraft during ground maneuvering.
