Four-wheeled scooter-type vehicle

A scooter-type vehicle, defining a longitudinal direction, a transverse direction and a vertical direction in a neutral position, the vehicle comprises:

• a frame which includes a crossmember located in the vicinity of a median vertical transverse plane of the vehicle;
• a platform, the platform being mounted on the crossmember of the frame in a pivoting manner about a first inclination axis which is longitudinal and median, the vehicle including means for returning the platform in the neutral position, in which the platform is substantially horizontal;
• a right running gear and a left running gear, each including a front wheel and a rear wheel, the front wheel of the right running gear and the left running gear and/or the rear wheel of the right running gear and the left running gear being steered, the right running gear and the left running gear each including, for each front wheel and each rear wheel, at least one arm which is arranged substantially parallel to a mid-plane of the front wheel and the rear wheel, the at least one arm having one end linked to an axis of the front wheel and the rear wheel and another end mounted on a connecting piece, the at least one arm being mounted on the connecting piece in a pivoting manner about a steering axis which, in the neutral position, is disposed substantially in a plane of the front wheel and the rear wheel and is inclined downwards in a direction of the front wheel and the rear wheel, the connecting piece being mounted on the crossmember of the frame in a pivoting manner about a second inclination axis which is longitudinal and lateral;
• a steering column, the steering column being mounted orthogonally on the platform, substantially vertically in the neutral position, and in a pivoting manner about its axis relative to the platform;
• a transfer device connecting the steering column and the at least one arm, so that rotation of the steering column about its axis causes the turning of the front wheel of the right running gear and the left running gear and the rear wheel of the right running gear and the left running gear by pivoting the front wheel of the right running gear and the left running gear and the rear wheel of the right running gear and the left running gear about the steering axis;
• two coupling members, each connecting the platform and the connecting piece, so that inclination of the platform relative to the crossmember, by pivoting the platform about the first inclination axis, causes inclination of the right running gear and the left running gear relative to the crossmember, by pivoting the connecting piece about the second inclination axis;
• and
• wherein the vehicle is devoid of axles.
