Abstract:
The present invention relates to a forecarriage of a rolling motor vehicle with three or four wheels, comprising: a forecarriage frame (16); at least one pair of front wheels (10′, 10″) kinematically connected to each other and to the forecarriage frame by a kinematic roll mechanism (20) which enables the same to roll in a synchronous and specular manner; an anti-roll system (100) comprising a rod (110) having a first (111) and a second end (112) opposite each other which connect by means of hinging means (101′, 101″ and 102′, 102″) a first (60) and a second anchoring portion (60) of forecarriage (8) directly to each other. At least one of said first (60) and second anchoring portions (60) is subject to roll movements of said two front wheels (10′, 10″). The hinging means (101′, 101″ and 102′, 102″) are configured to passively follow the movements of two anchoring portions. The hinging means (101′, 101″) at the first end (111) of the rod comprise at least a first roll hinge (101′) which has its hinge axis substantially orthogonal to a rolling plane of the two front wheels and is connected to the first anchoring portion (60). The anti-roll system comprises a first blocking device suitable to reversibly block a rotation angle α of rod (110) with respect to the first roll hinge 101′ at the first end (111). Such an angle of rotation a corresponds to the roll angle of the rod.
