The scooter is seen mainly in children's sports games transport, and toys.

Known scooters, which are, in General, two-wheeled cart with a platform for the feet, the front wheel which is a driven wheel, and the movement of which is produced by repulsion from the road surface by the foot, roll and elevation /JP 2002-790 A/.

Inertial character of the motion of such scooters limits their games and transport opportunities, and they often prefer bikes despite a number of advantages inherent to scooters, such as a convenience store.

The problem to which the invention is directed, is to increase gaming and transportation opportunities for the scooter.

Technical results of the invention are the absence of the constant need for the rider to push off from the road and the possibility of achieving a higher speed and achieved while maintaining the compactness of the scooter.

The aforementioned problem is solved and results are provided so that the front driven wheel scooter is equipped with a belt drive consisting of one or two functionally equivalent devices, in each of which one end of the exhaust /drive/ belt associated with the mobility of the “up-down” from the mentioned wheels rule the m scooter, and second coils on the drum or spool, connected or associated with the driving member of the overrunning clutch, which is connected with the axis of the wheel and one end of a return spring, the other end of which is connected with a plug or equivalent element of the wheel suspension.

The working stroke of the actuator is a steering movement “over”, in which works the entire body of the rider and the power that can be transmitted to the wheel, greatly exceeds the capabilities of the hands.

Paired drive option /two belts, clutches and springs/ excludes perekashivayutsya moments on the steering wheel and the wheel.

The actuator is also applicable in embodiments, non-rigid, for example, hinge, pair suspension front wheel trolley aircraft. The ability to move the steering wheel scooter upward and downward from the controlled wheel is characterized at the functional level. In private versions of the devices are used, known in the art methods.

In one embodiment, the execution of his scooter wheel having a slot, with the possibility of forward movement planted profiled on the steering shaft front steering wheels. The device is easy.

In another preferred embodiment of the device for convenience with mobility wheel scooter this wheel is provided with elements to control the effect of the position lock steering degree of freedom “up-down”. The preferred location is the steering arm. The latch and its controls described at a functional level and are known devices of this destination. Preferred are bystrorastvorimye tabs.

To clarify the essence of devices attached drawing, which shows an example of executing a scooter.

Scooter /see the drawing is a two-wheeled, provided a platform for the feet of the truck, the front wheel 1 which is controlled by the steering wheel 2. A wheel, having a slot, with the possibility of forward movement planted on the shaped /square section/ steering shaft 3 fork 4 wheels. The wheel has a belt drive, one end of the exhaust belt 5 which is connected with the wheel, and the second coils on the drum 6, which is connected with the driving member overrunning clutch, slave link which is connected with the axis 7 of the wheel. The drum is connected with one end of the return spring 8, the other end of which is connected with the fork of the wheel. On the handles of the steering wheel scooter has the levers 9, through which is controlled by the latch regulating the ability of the translational movement of the steering wheel on the shaft /friction type/. The steering wheel is locked on the shaft is available at the end of the last limiter 10, which also has a protective function /protection rider from naprawianie on the shaft/. RA is a by the actuator stroke is the movement of the steering wheel. Outside the operating mode of the drive wheel is on the latch.

Scooter, containing two-wheeled provided a platform for the feet of the truck, the front wheel which is controlled by steering, characterized in that its front wheel has a drive consisting of one or two functionally equivalent devices, any of which one end of the exhaust belt associated with having mobility up and down the wheel of the scooter, planted the corresponding socket on the shaped steering shaft fork or her equivalent of an element of the suspension of the front wheel and the second coils on the drum or reel of the leading link overrunning clutch connected with the axis of the wheel and provided with a return spring, and the wheel is locked mentioned the shaft limiter, which also has a protective function, and on the arms of the steering wheel has controls for the release of its position on the steering shaft.
