Vehicle having three or more tilting wheels with reactive constraint suspension
11084549 · 2021-08-10 · ·

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.

IMPROVED TILTING SUSPENSION FOR A VEHICLE

A tiltable vehicle (100) is described comprising a vehicle frame (102, 108), one front wheel (124), two rear wheels (112A, 112B) and two swing arms. The swing arms are pivotably coupled to a pivot point (121) on the vehicle frame at a first end, and to one of the rear wheels at an opposing end. A swing arm (41) is rotatable around a rotational axis (42) lying in a plane of symmetry of the vehicle frame (102, 108). Each of two linkages (63, 64) is coupled at a first end to one of the swing arms at the pivot point. The vehicle comprises two connection arms (53, 56) arranged between the linkages (63, 64) and one outer end of the rocker arm (40). The connection arms comprise resilient members (61, 62) comprising a number of Belleville springs arranged in at least two groups of rings so as to create a non-linear spring characteristic.

Three-wheeled tilting vehicle

A tiltable vehicle is configured to transform between an autonomous mode and a rideable mode by pivoting the handlebars and steering column of the vehicle about a pitch axis. In the autonomous mode, the steering column is folded back toward the chassis and a tiltable chassis of the vehicle is prevented from tilting. In the rideable mode, the steering column is unfolded and the chassis is free to tilt. In some examples, a tiltable vehicle includes features beneficial for vehicle-sharing, such as parking devices or a basket. These features may be included on any suitable vehicle and are not limited to use on transforming vehicles.

NARROW THREE WHEELED VEHICLE WITH STABILIZING AND MODULAR MECHANISMS

A three-wheeled vehicle includes a vehicle frame supported by a single wheel engaging the ground in the front and two wheels engaging the ground in the rear. The operator area of the vehicle may include seating for a driver and a passenger, one in front of the other. The three-wheeled vehicle is uniquely designed so that it can be easily modified by addition or removal of additional structures after it is purchased. The vehicle is ultra-narrow but achieves stability by unique mechanisms.
