The invention relates to a transport engineering, more specifically to the undercarriage parts of vehicles.Known wheel propulsion with two wheels, recorded from bokovo the LCD of the wheels, and the drive to move the rollers on the inner tracks, made coaxial to the axis of the wheels, and wheel rotation.The lack of such wheel movers that when moving on the road of the outer wheel bearing is shifted with respect rollers, which leads to changes in torque and tractive effort. In addition, variables fulcrum wheels on the road lead to the slipping of the wheels, which reduces the cross.Known wheel propulsion, containing two wheels are fixed against lateral displacement, a rack connected to the upper sides and planted lower sides of the rollers on the inner tracks, made eccentric to the axis of the wheels, and the actuator for moving the rollers on the inner tracks and the rotation of the wheels, and the wheels are straight sections of the outer supports and associated with the alternate rotation.This wheeled vehicle when moving rollers on the inner track and support wheels straight section of the outer poles on the road traction power has a positive value. However, when you move the rink on the inner track and the rolling wheel on another straight line segment of the outer wheel bearing will be located sparable close on the technical nature of the claimed device is wheeled mover, containing two parallel spaced wheels fixed against lateral displacement relative to each other, two hours, interconnected upper parts, each of which communicates with the respective wheels through mounted on the axis at the bottom of the roller, obkatyvalisj executed on the inner part of the wheel eccentric to the axis of the ring track and the drive wheel rotation, the track wheels are interconnected in antiphase relative to their eccentricities.In such a wheeled vehicle when moving rink on the inside track, an inclined towards the outer bearings of the wheel, traction power and torque have a positive value. However, when you move the rink on the inside track, receding from the outer bearings of the wheel, traction power and torque are negative. The fence one stands on one wheel to rotate the other pole of the other of the wheel causes rotation of both wheels in different directions.These factors reduce the maneuverability and traction wheels when moving on the road, which is a disadvantage of such wheel movers.The aim of the invention is increased the Olesno propeller containing two parallel spaced wheels fixed against lateral displacement relative to each other, two hours, interconnected upper parts, each of which communicates with the respective wheels through mounted on the axis at the bottom of the roller, obkatyvalisj executed on the inner part of the wheel eccentric to the axis of the ring track and the drive wheel rotation, the track wheels are interconnected in antiphase relative to their eccentricities, each wheel is equipped with two anchor pads, made in the form of grooves in the body of the wheel, and two clamps for engagement with the supporting platforms other wheels at the moment when the site of one of the wheels and lock the other wheel are located opposite each other and are at the bottom of the wheels when they are rolling.In Fig. 1 schematically shows a wheel propulsion, side view; Fig. 2 - section a-a in Fig. 1; Fig. 3 - section b-B in Fig. 1.Wheel propulsion contains two wheels, right 1 and left 2, two racks 3 associated upper sides movably with the hard center of the wheels and planted lower sides of the rollers 4 on the inner tracks, made eccentric to the axis number is olaso provided with two support pads 7, located in the body of the wheel, and clamps 8, located between the reference sites. The lower portions of wheels movably connected to the at least one latch that is located ahead in the direction of motion, and reference platform for wheel rolling on the supporting surface of the latch and other parts of wheels have the same connection through the bevel 9, performed on the latch, and a spring 10 that is associated with the wheel lock.Wheeled mover includes a foot actuator for moving the rollers on the inner tracks and wheel rotation, to install the passenger's feet on rack coaxially to the axis of rotation of rollers mounted pedal 11.Wheel associated with the opportunity for independent rotation in the plane of the wheel and secured against lateral displacement by a washer 12, which connects the hard centers of the wheels.For fixing the mutual position of the reference areas on the road both wheels lock has a cylindrical part 13, and in the area of foothold performed guides 14.The left and right rack loaded with a weight of a passenger due to the installation of his feet on the pedals. Rollers mounted on the supporting areas on the road where the inner track as close as possible to the outer supports of the wheels, and kartirovanie release the left wheel with the base platform of the right wheel.Wheeled mover may contain two or more wheels.Wheels can have a circular outer rim, can be oval, with straight sections, etc.The inner tracks may be cylindrical in shape, with straight sections, etc.Reference sites can be made in the form of a closed groove in which is located the latch.Wheel propulsion works as follows.To move the wheel propulsion in the direction of movement of the left leg with the pedal 11 is moved left rack 3 and rink 4 forward reference to section 6 on the adjacent wheel, on its upper part, and wheel left wheel 2 around its retainer 8 on its support surface to lock the upper support section 5 on the road, on the road surface.Torque of the left wheel to form the left leg with a focus right foot on the right wheel 1, is blocked from turning back, focusing the left wheel through the clip on the support platform 7 right wheel. This provides a positive torque, independently from the support of the left wheels on the road.At the end turn left bevel wheel 9 is located in the reference area is received from the springs 10 and axial displacement of the retainer in the body of the wheel is located on the frame of the left wheel, and it is locked from turning back.Right wheel rotates similarly to the left.At the time of the release of one wheel and the setting of the other latch on the other of the supporting ground wheels secured against mutual displacement contact sections 5 on the road cylindrical part 13 and the guide 14.The wheels are fixed against lateral displacement by a washer 12, planted on the hard centers of wheels rotatably.
