The rate of the tilt of the steering post, towards the inside periphery of the turning curve, is proportionally related to the pivoting rate of the steering post, and configured to vary depending on speed. The scooter further includes a deck assembly having a standing board and a rear wheel assembly. An interface assembly interconnecting the deck assembly with the steering assembly. The scooter is foldable and may include a detachable bag.

Riding devices such as bicycles, scooters, and personal mobility devices include four rigid bodies, three revolute joints, and further include a front hanger and wheels that universally rotate around a front hanger pivot axis, a front truck assembly with twist steering, and a rear truck assembly with lean steering, where the twist steering is independent of the lean steering, and where a deck rotates about a longitudinal roll axis between a front virtual pivot point in the front hanger and a rear virtual point in the rear hanger.

A vehicle including a front wheel, a pair of left and right rear wheels disposed diagonally behind the front wheel on a left side and a right side, and a pair of left and right support members extending in a front-rear direction and including support portions rotatably supporting the pair of left and right rear wheels. The pair of left and right support members are disposed so as to be separated from each other by a predetermined distance so that a front wheel of another vehicle configured to have a same shape as the vehicle is insertable into a gap between the pair of left and right support members from a rear side.

A steering linkage assembly includes a support member; a connecting portion rotatably arranged on the support member and connected to an external steering member; a first steering linkage; a first ball head rod provided with one end connected to a ball head at a first end of the first steering linkage and the other end connected to the support member; a second steering linkage; and a steering rotating shaft mounted at a first end of the second steering linkage and rotatably connected to the support member. A rotating centerline of the steering rotating shaft is not parallel to that of the connecting portion. An included angle is formed between a connecting line of ball head centers of the first and second ball head rods and a connecting line of a rotating center of the steering rotating shaft and a ball head center of the third ball head rod.

A leaning vehicle including a braking mechanism, a linkage mechanism configured to cause a body frame of the leaning vehicle to lean leftward or rightward, a lean lock mechanism configured to restrict leftward leaning and rightward leaning of the vehicle body frame, and an interlocking mechanism configured to actuate the braking mechanism and the lean lock mechanism. The interlocking mechanism includes an operation input section configured to input a first operating force, a brake-operation-input section configured to input a second operating force, an operating force distributor configured to distribute the first operating force input by the operation input section to the lean lock mechanism and the braking mechanism, and a brake actuator configured to actuate the braking mechanism by the first operating force distributed to the braking mechanism by the operating force distributor, or by the second operating force input by the brake-operation-input section.

The invention concerns a wheeled vehicle (10) which is able to regulate its lateral tilt. In a preferred aspect the vehicle (10) comprises a seat (28) for supporting a rider, and a chassis (18) which carries the seat. A steerable wheel (12) is carried by the chassis and is operably coupled to a steering arrangement (30, 34) for turning the steerable wheel (12) to effect steering of the vehicle (10). A left wheel-bearing arm (66) carries a left wheel (14) and is pivotally coupled to the chassis (18), so that pivotal movement of the left wheel-bearing arm (66) provides up and down movement of the left wheel (12) relative to the chassis (18). A right wheel-bearing arm (68) carries a right wheel (16) and is pivotally coupled to the chassis (18) to be movable independently of the left wheel-bearing arm (66), so that pivotal movement of the right wheel-bearing arm (68) provides up and down movement of the right wheel (16) relative to the chassis (18). A left control line (76) is led from a left tether (79) on the left wheel-bearing arm (66) to an actuator (84) carried by the chassis (18), so that upward movement of the left wheel (14) relative to the chassis is restrained by the control line (18). A right control line (82) is led from a right tether (78) on the right wheel-bearing arm (68) to the actuator (84), so that upward movement of the right wheel (16) relative to the chassis (18) is restrained by the right control line (82). The actuator (84) is operable in a first direction to pay out the left control line (76) whilst drawing in the right control line (82), permitting the left wheel (14) to move up relative to the chassis (18) and causing the right wheel (16) to move down relative to the chassis (18), thereby causing the vehicle (10) to tilt toward the left. The actuator (84) is operable in a second direction to pay out the right control line (82) whilst drawing in the left control line (76), permitting the right wheel (16) to move up relative to the chassis (18) and causing the left wheel (14) to move down relative to the chassis (18), thereby causing the vehicle (10) to tilt toward the right.
