ローリング制御部を備えたローリング式モータビークルの前部キャリッジ

Japanese Patent JP7121008

B2

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; a roll control 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″; 102′, 102″) a first (60) and a second anchoring portion (60) of forecarriage (8) directly to each other. At least one of said first and second anchoring portions is subject to roll movements of said two front wheels. The hinging means are configured to passively follow the movements of the two anchoring portions. The hinging means (101′, 101″) at the first end 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. The roll control system comprises a first damper device suitable to dampen—in a predetermined angular range—the rotation movements of the rod with respect to the first roll hinge at the first end (111). The above angular range corresponds to the angular roll range of the rod.
