Rocker landing gear
The main feature of the rocker landing gear is that the wheel is connected to the piston rod of the shock absorber via a rotatable rocker arm. The shock absorber can also double as a bearing strut. This type of piston only bears the axial force and does not bear the bending moment, so the sealing performance is good, the initial pressure of the shock absorber can be increased to reduce the size of the reducer, and the disadvantage of the pillar type is overcome, on the modern aircraft. Has been widely used. The disadvantage of the rocker type landing gear is that the construction is complicated and the joint is subjected to a large force, so that it is also worn during use.
Float landing gear
The pontoon landing gear is used on amphibious aircraft. Because amphibious aircraft need to be able to land safely on water and on land, the pontoon landing gear has a special landing on the water, in addition to the ordinary retractable wheels. A pontoon that cannot be recovered. The wheel of the pontoon landing gear is retracted inside the pontoon. In order to facilitate the steering on the water surface, some pontoons have a tail rudder at the end.
