A caster board can include a front platform section connected by a torsion bar or other neck portion to a rear platform section. The caster board can be convertible between a first configuration in which the caster board has three wheels, and a second configuration in which the caster board has two wheels. In the first configuration, the rear platform section can be supported by two wheels laterally offset from a longitudinal axis of the caster board. In the second configuration, the rear platform section can be supported by one wheel aligned with a longitudinal axis of the caster board. The rear platform section can include at least three mounting locations configured to have caster assemblies installed therein.

A motorized skateboard has a maneuverable rear truck. The riding platform on which the user stands includes a rotatable steering platform that the rider can step on with his rear foot. In the nominal position the steering platform extends slightly above the rest of the riding platform and is locked from rotating. When a user steps on the steering platform, the steering platform gets pushed downward against a spring. The downward movement causes a wedge to force apart two pawl level arms, thus disengaging respective pawls from a ratchet thereby unlocking the steering. In this position the steering platform is rotationally coupled to the rear truck through two spur gears acting in serial such that as the user pivots his foot clockwise, the rear truck turns counterclockwise, and vice versa. The result is a steering motion that is similar to turning a snowboard.

A multi-link wheel base includes a main body composed of a plurality of links connected in series and wheels provided on the main body, and the wheels are provided on the link assembly the link assembly includes an intermediate link and an end link, wherein both sides of the intermediate link are provided with a rotational connection position, one side of the end link is provided with a rotational connection position, and the rotational connection positions on the adjacent link assemblies are rotationally connected by means of a connecting device.

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.

A skateboard includes a board body having a first section and a second section, at least a first wheel set connected to the first section, and at least two second wheel sets connected to the second section. The first wheel set includes a first base protruding from the first section. Each second wheel set includes a second base protruding from the second section and defines a reference line passing through a center of the second base. Both of the bases slope at an angle of 5 to 35 degrees respectively. An angle of not more than 60 degrees is formed between the reference line and a baseline passing axially through a center of the board body. The skateboard moves forward when the wheel sets are triggered by twisting a body of a user and a moving direction is changeable by shifting a center of gravity of the user.

A vehicle for transporting a passenger in a standing position includes a frame, a rear axle assembly disposed at a rear end of the frame, a front suspension assembly disposed at a front end of the frame, a rear deck attached to the frame to accommodate a trailing foot of the passenger, a front deck attached to the frame to accommodate a leading foot of the passenger, and a driveshaft extending forward from the rear axle assembly such that the driveshaft transmits power to the rear axle assembly.

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 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.
