SAFETY WHEEL FOR A TRANSPORT MEANS

摘要

The invention relates to the tyre industry , in particular to a structural design of tyres . The inventive transport means wheel comprises a rim and a hollow tyre, which is arranged therein and reinforced by an elastic frame, wherein the cavity formed by the tyre internal surface and the rim surface contains a damping device which is embodied in such a way that it is closed in the form of a multi-thread spring and whose cross-section fits in the cavity contour. The tyre elastic frame comprises rings which are interconnected, positioned along the tyre circumference on the side of a tyre thread and the outermost rings are attached by U-shaped elements to the pair of rings arranged along the tire beads, wherein the outermost rings and the rings arranged along the tire beads are additionally attached by means of zigzag-shaped elements fixed between the radial parts of the U-shaped element. Tubular elastic supporting elements coaxially mounted on both cylindrical surfaces inside the cavity are provided with equally spaced axial slots which are embodied on the face-to-face surfaces thereof and in which the threads of the damping device are arranged. The inventive transport means wheel is more reliable and has a longer service life.
