WHEEL WITH QUASI GAS FILLER FOR LUNAR AND PLANETARY TRANSPORT AND METHOD FOR ITS ASSEMBLY Russian patent published in 2019 - IPC B60B19/00 B64G1/16 

FIELD: transportation.

SUBSTANCE: wheel contains a rim with mounting flanges, a rim disk, a tire made of a chainmail net, and the tire with the rim are rigidly interconnected by means of pressure rings with fasteners as a whole. Cavity formed by the inner surface of the tire and the rim is filled with quasi-gas filler in the form of solid spherical elements. In the rim there are filling holes with flange plugs on the screws. Rim profile is equidistant with respect to the tire profile made in the form of an arch inscribed in an oval, the length of the major axis of which is equal to the width of the tire profile, and the length of the minor axis is twice the height of the tire profile, taking into account certain ratios. Method of assembling a wheel with a quasi-gas filler is as follows: tire pattern is constructed taking into account the calculated parameters of the arched profile of the tire – width b and height h, the tire blank is cut out from at least two layers of chainmail mesh in the form of a rectangular cloth with dimensions π⋅D_t⋅L, where: π – mathematical constant; D_t – tire diameter; L is the arc length of the arch of the tire profile, then the cloth is rolled up and connected in the form of a shell, the resulting tire is tightly fitted onto the rim and rigidly connected to the rim by means of pressure rings with fastening elements around the rim of the landing flanges, forming a single unit. Next, in the cavity formed by the inner surface of the tire and the rim, a quasi-gas filler in the form of solid spherical elements is loaded through the filling holes in the rim, applying vibration loading, then the filling holes are closed with flange plugs on the screws.

EFFECT: improving the performance, maneuverability, reliability, shock-absorbing ability, as well as simplifying the tire removability of the wheel during operation in natural conditions of the surface of the Moon and planets, as well as improving manufacturability, performance of the assembly method and tire quality.
