Patent ID: 7401794

Claim:
A vehicle comprising: a suspended body, at least two wheels each mounted on a wheel support, each wheel support being mounted on a suspension device comprising a suspension support and means for guiding the wheel support relative to the suspension support, the suspension device allowing a vertical displacement of the wheel support relative to the suspension support, the size of the displacement being sufficient to produce a vertical suspension movement required, and at least one first wheel of the at least two wheels being arranged transversely on one side of the suspended body and at least one second wheel of the at least two wheels being arranged on the other side of the suspended body, wherein for each of the first and second wheels, each suspension support is connected to the suspended body by a height variation mechanism which allows the relative height of the each suspension support relative to the suspended body to be varied, each height variation mechanism is actuated by a height control means, the vehicle centralized further comprises centralized control means controlling the height control means, wherein control of the height control means on each side of the suspended body is coordinated so that on that side of the suspended body, the relative height of each suspension support is varied simultaneously, and each height variation mechanism comprises a device having four pivot points that form a deformable parallelogram in the median plane of the vehicle, said parallelogram receiving on one side the respective suspension support and being permanently attached on the other side to the suspended body, the height control means enabling said parallelogram to be deformed.
