ROLLING MOTOR VEHICLE

This invention relates to a rolling motor vehicle with three or four wheels, comprising a frame that extends from a forecarriage , which supports at least two front wheels ″, to a rear which supports one or more rear wheels . The frame defines an accommodating area for a driver P. The forecarriage in turn comprises: —a forecarriage frame ; —at least one pair of front wheels ″ kinematically connected to each other and to the forecarriage frame by means of a rolling 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 , said axle journal being mechanically connected to a rotation pin of the wheel in order to support it rotatably around an axis of rotation R′-R′, R″-R″; —a roll control system of the motor vehicle; —suspension means which guarantee each axle journal at least one spring suspension movement with respect to said rolling kinematic mechanism . The roll control system comprises a rod , which connects the two front wheels directly to each other at the respective axle journals at its two ends by means of hinging means which enable said rod to passively follow the movements of the axle journals , the roll movements of the two front wheels and of the respective axle journals causing changes in the lying position of said rod with respect to a vertical projection plane, which is transverse to a centre line plane M-M of the motor vehicle. The rod is usable directly or indirectly by the driver P as a command element of the roll control system to control the rolling movements of the two front wheels without having to put his feet on the ground, adjusting the lying position of the rod itself with his own body. Said command element is disposed so as to be accessible and maneuverable by the driver P from the accommodating area
