Technical Examples

A vehicle with protection against the effects of an exploding land mine is provided, in which a military wheeled vehicle is provided with wheel axels and drives built into front and/or rear building blocks. The vehicle is divided into multiple building blocks, although a three block construction is desirable (i.e., a front building block, a rear building block, and a main building block). A residual mobility of a remaining portion of the vehicle is preserved, even though one of the front building block or the rear building block is separated from the main building block due to the explosive shock wave generated by driving over and detonating a land mine, because each of the front building block and the rear building block has a drive for rotating the wheel axel connected to the block.
