Wheel support assembly for propping up a motor vehicle, a caravan, a commercial trailer or a mobile home

The assembly (1) has a square shaped protruding structure (2) at an upper side, and a corresponding complementary recovered structure (3) at a lower side. The upper side is provided with a largely closed surface, and a core is provided with a strut structure such that an outer edge shape of implementation is partly formed as a repeated structure in the strut structure. The protruding structure is formed as a circular disk element, and the recovered structure is formed as a disk-shaped recess (4), where the assembly is made of wood, metal and plastic that contains reinforcing elements.
