Abstract

In neutral position, the scooter (1) has a longitudinal plane of symmetry and comprises: - a steering column (2) which is generally vertical and mounted for pivoting in relation to a baseplate (11) about a steering axis (A2) to enable steering of a front wheel (4); - two side rails (3) on which the feet of the user are supported, each side rail comprising a front part which is assembled on the baseplate (11) so as to pivot about an oblique pivoting axis (A3); - two back wheels (5), each one being assembled on a support (19) in a manner rotating about the axis (A5) thereof, said support (19) being assembled for pivoting in relation to the rear part of the corresponding side rail (3) about an articulation axis (A19) which is tilted towards the front, in relation to the vertical, at an angle γ of between 0° and 30°.

Abstract

The vehicle (1) comprises: -a chassis that comprises a front crossmember (2) and a rear crossmember (3); - a nacelle (10) receiving a person or a load, mounted pivoting relative to the central part of the crossmembers (2, 3) about a substantially longitudinal articulation axis (6), the centre of gravity of the nacelle being located beneath said articulation axis (6); -a front axle and a rear axle each comprising two movement supports (4, 5) for moving on the ground, each movement support being connected to the end part of the corresponding crossmember by a link system (17); the crossmembers, located in the top part of the nacelle, being separate parts linked to each other only by the nacelle, via the articulation axis, so as to be able to pivot about the articulation axis (6) independently of one other.
