A suspension for a skateboard, comprising a pair of steering knuckles on opposite sides of a chassis frame of the skateboard, a pair of upper control arms connected between the pair of steering knuckles and the chassis frame, a pair of lower control arms connected between the pair of steering knuckles and the chassis frame, and a first spring damper connected between the pair of upper control arms.

The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not proportionally responsive to tilting over the expected range of tilting.

The wheeled riding device employs a frame system mounted to the bottom of the deck, independent suspension links pivotally connect to the wheel assemblies enabling four wheel independent suspensions. A centrally mounted steering and suspension pivot, provides both steering control and suspension attachment for the shock and spring. The device is controlled by the rider using body movement, and a hand held remote when electrically driven. Whether manually or electrically propelled the invention brings improvements in both steering and ride stability while riding over adverse terrain.

A stroller-attachable skateboard apparatus comprises a skateboard, a connection rod and and an adjustable mounting bracket. The connection rod includes a board engagement portion, a stroller engagement portion and a rod axis. A rod securement interface of the skateboard receives the board engagement portion and rigidly retains it therein by way of an actuatable locking pin such that the rod axis extends laterally of the skateboard's longitudinal axis. The stroller engagement portion is axially receivable by a rod receiving element and releasably axially locked therein by way of a first spring-biased actuator element. The rod receiving element may be provided as part of the adjustable mounting bracket or as a pre-existing wheel axle end from which a stroller wheel has been removed. The mounting bracket facilitates highly-adjustable mounting of the skateboard to a frame member of a standard, unmodified stroller. The connection rod may also be adjusted for extension length.

A standing-ride type moving device includes: a board; wheels that are disposed on right and left sides of a front side and a rear side in a traveling direction of the board; drive units that is configured to independently rotationally drive the wheels disposed on the front side in the traveling direction of the board; a first sensor that is configured to detect a shift in the center of gravity of the rider riding the board; a steering board that is disposed on the front side in the traveling direction of the board; a second sensor that that is configured to acquire rotation information of the steering board; and a control unit that is configured to control the drive units.

The present steerable wheel assembly incorporates a lean-to-steer mechanism into an inner race of a roller bearing, while a wheel is mounted to an outer race of the roller bearing. A shaft extending from the mechanism is attached to a body, and the mechanism acts to steer the outer race and the wheel about a vertical steering axis when the shaft is tilted about a horizontal axis. The mechanism can be a pivot joint, providing a linear steering response, or can be a lean-to-steer mechanism that provides a non-linear response where the steering action is not consistently responsive to tilting over the expected range of tilting. The present non-linear lean-to-steer mechanisms can also be incorporated into alternative lean-to-steer devices, and alternative mechanisms can employ tracking structures to coordinate tilting motion of a first moving element with steering motion of a second moving element to provide a non-linear lean-to-steer response.

A skateboard axle assembly is described, having a connection plate for mounting the axle assembly to a skateboard deck and a wheel axle. The wheel axle has two ends, to each of which a wheel can be mounted. The wheel axle is movably coupled to the connection plate by two articulated arms. In addition, a skateboard having at least one skateboard axle assembly is described.

A skateboard comprising a board having an independent suspension and steering assembly connecting two wheels to the board. The suspension assembly comprises a support frame rotatably coupled to an underside of the board. The steering assembly comprises a steering crank fixed to and extending from an underside of the board. The suspension assembly further comprises for each wheel: a spindle for rotatably supporting the wheel; a knuckle for holding the spindle; an upper and a lower suspension arm pivotably coupled to the support frame at an upper and at a lower point of the support frame, respectively, and also pivotably coupled to the knuckle at an upper and at a lower point of the knuckle; and a spring for resiliently holding the knuckle against the board. The steering assembly further comprises for each wheel: a tie rod coupled by a ball joint to the steering crank and to the knuckle.

A scooter with a footboard providing a contact surface for a user of the scooter, with a front axle including a first front wheel and a second front wheel and a rear axle comprising a first rear wheel and a second rear wheel, and with a steering column for steering at least the front wheels. Inclination of the footboard about a roll axis of the footboard effects a steering angle of the two front wheels in a first direction and, at the same time, a steering angle of the two rear wheels in a second direction opposite the first direction. The disclosure further relates to a method for operating such a scooter.

A motorized or non-motorized multi-wheeled skateboard assembly including a board deck to support the user, a board having a top side, a bottom side, a flat and a rounded end, linkages, hinges, a steered wheel assembly, an input device and a drive assembly. The steered wheel assembly improves maneuverability, turn radius, and stability. The user steers the skateboard assembly by altering pressure between the top side first end and the top side second end causing the steered wheel to turn, thus manually steering the board. This change in pressure is also altered between the first linkage and second linkage in direct or inverse relation to altering pressure between the top side first end and the top side second end of the board deck.
