Abstract

The vehicle (1) comprises: - a chassis (2) comprising a substantially central crossmember (20); - two running gears (4) each comprising a front wheel (5) and a rear wheel (6), an arm (42) connected to the spindle of each wheel being mounted on a connection piece (50) so as to be able to pivot about a vertical or tilted pivot axis (A), the connection piece being mounted on the crossmember; - a seat (3) mounted so as to be able to rotate relative to the chassis about a longitudinal axis (A3), with return to neutral; - four coupling members (70), each connecting the seat and one of the arms connected to a wheel spindle, such that the rotation of the seat relative to the chassis pivots each wheel about the pivot axis (A); the vehicle (1) not having axles.
