Abstract

two rear wheels, each one being rotatably mounted on a support about its axis, the support being pivotally mounted relative to the rear portion of the corresponding spar about a hinge axis which is inclined forwards, with respect to the vertical, by an angle γ comprised between 0° and 30°.

Abstract

The vehicle includes: a chassis which includes a front cross-member and a rear cross-member; a nacelle receiving a person or a load, pivotally mounted relative to the central part of the cross-members about a substantially longitudinal hinge axis, the center of gravity of the nacelle being situated below said hinge axis; a front train and a rear train, each including two movement supports on the ground, each movement support being connected to the end part of the corresponding cross-member by a connecting system; the cross-members, situated in the upper part of the nacelle, being separate pieces linked together only by the nacelle, via the hinge axis, so as to be able to pivot about the hinge axis independently of one another.
