Patent ID: 11084549

Abstract:
The invention describes a vehicle (100) having three or more tilting wheels comprising a main frame (2) provided with a suspension group (3) for at least two wheels (25). The suspension group (3) is joined to the main frame (2) through a hinge (8) that allows the free rotation of the main frame (2) with respect to the suspension group (3) along the axis of the hinge (8). The suspension group (3) comprises a pivoting arm (6) for each wheel (25). Each pivoting arm (6) is constrained to the suspension group (3) through the interposition of one or more elastic elements (9) consisting of elastomers. The elastic elements (9) operate as suspension or damping means, or with both of the associated functions. Each elastic element (9) is compressed and works under pressure inside a cavity obtained between one or more pins (7) having a closed polygonal section, operatively associated with the hinge (8), and one or more channels (32) having a closed polygonal section, obtained in the suspension group (3). The closed polygonal section of each channel (32) has a compatible shape and has a larger surface with respect to the closed polygonal section of each pin (7) that rotates inside such a channel (32) having a closed polygonal section.
