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.

Disclosed is a forecarriage of a rolling motor vehicle with three or four wheels, comprising:a forecarriage frame;at least a pair of front wheels kinematically connected one to each other and to the forecarriage frame by means of a first kinematic mechanism which enables the front wheels to roll in a synchronous and specular manner, each wheel being connected to said rolling kinematic mechanism by means of a respective axle journal, the latter being mechanically connected to a rotation pin of the wheel in order to support it rotatably around an axis of rotation;means of suspension which provide each axle journal at least one spring suspension movement with respect to said rolling kinematic mechanism;a steering device which kinematically connects the axle journals to each other so as to command the rotation of the axle journals around respective steering axes of each front wheel

The present invention discloses a three-wheeled motor vehicle having a lockable tilting mechanism. The tilting mechanism is configured to tilt the vehicle at any angle without the need for a driver to put their feet on the ground outside the vehicle. The tilting mechanism is further configured to lock the tilting of the vehicle at any desired angle by the driver. The present invention enables the driver to alter the lean from within the vehicle if the lean is locked in an undesirable position. The tilting mechanism is further configured to enable the driver to lock or unlock the lean of the vehicle in a manner that allows the driver to intuitively switch between steering and counter-steering.

A vehicle is configured to travel, when a vehicle velocity is within a velocity range from not less than a first velocity of at least zero to not more than a second velocity larger than the first velocity, in a mode in which a vehicle body is leaned by a lean mechanism according to an input into an operation input unit, and a wheel angle of a turn wheel changes following a lean of the vehicle body. A natural frequency of roll oscillation of the vehicle body is either within a range of smaller than a reference frequency or within a range of larger than the reference frequency, the reference frequency being a frequency at which oscillation of the wheel angle of the turn wheel has phase delay of 90 degrees relative to the roll oscillation of the vehicle body in its width direction.

A motor vehicle forecarriage comprises a forecarriage frame, a pair of front wheels kinematically connected to the forecarriage frame by means of an articulated quadrilateral, said articulated quadrilateral comprising a pair of cross members, hinged to the forecarriage frame in correspondence of middle hinges, said cross members being connected together, in correspondence of opposite transverse ends, by means of uprights pivoted to said transverse ends in correspondence of side hinges, the cross members and the uprights defining said articulated quadrilateral. Each of the uprights guides and supports a stub axle of a front wheel, each upright extending from an upper end to a lower end, wherein the left and right uprights rotatably support the left and right front wheels, respectively, around respective steering axes parallel to each other.
