The invention relates to wheeled propulsion vehicles terrain intended for movement on different soils in off-road conditions.

Known active wheel containing the hub, the sectional rim, force elements made in the form of one or more cylinders and acting on the rim to create traction, as well as the distributor for alternately supplying fluid power elements (author's certificate of the USSR No. 441176, CL 60 In 19/00, 1971 and No. 1641652, CL 60 In 19/00, 1985).

However, due to the use of flowable substances in hydraulic or pneumatic devices, which creates a pulling force that is similar to the active wheel develop low speed, hampered their movement is on the rise, and the backward motion is impossible.

Known wheel propulsion, containing a pneumatic tire, rim, disc symmetrically arranged around the circumference of additional lugs, or which is rigidly fixed to the drive, or is able to move in the direction of the axial line of the wheel propulsion (magazine Tractors and agricultural machines", 2002, №2, p.31, Fig. "Removable anti-skid device, a), b), C), d), e), f) "). Known wheel propulsion, containing a pneumatic tire, rim, disc symmetrically arranged on its circumference fingers, on which the ball is IRNA installed additional lug able to rotate in the plane perpendicular to the plane of the disk (the journal of Tractors and agricultural machines", 2002, №2, p.31, Fig. "Removable device, anti-skid, d) ").

The disadvantage of such devices is their passivity in the implementation of the traction wheel mover and a short period holding force of the lug.

An object of the invention is to improve traction properties propulsion by increasing the efficiency of the lug by giving its active properties of the feeding mechanism.

Figure 1 shows the wheel propulsion device in an inactive state, side view; figure 2 - wheeled mover in the movement lebanesse soils, side view.

Wheeled mover contains the pneumatic tire 1, the rim 2, the lug-pushers 3, disc 4, the surface of which is concentric with respect to the center distance "a" from the outer circumference of the propulsion symmetrical fingers 5. Each of the lugs-the pusher consists of earrings 6 for pivotally mounting the finger 5, the rod 7 and the Shoe for engagement with the ground 8. The lug-pushers 3 are angled β to the axial line of the wheel and have a length greater than the value "a". Each of the lugs-plunger 3 is spring-loaded relative to the drive wheel by means of a spring 9 and can cooks ivalsa relative to the finger in the plane of the disk at an angle the value of which is limited to the return action of the spring.

Wheel propulsion works as follows.

When driving on a hard surface road surface every lugs-plunger 3 by means of a spring 9 is in an inactive state so that the Shoe 8 is not in contact with the surface. When driving off-road wheel propulsion sinks into the soil to a certain depth so that when you turn the wheel, the Shoe 8 is also immersed in the soil. In case of slippage by increasing the peripheral speed of the wheel propulsion the lugs-plunger 3 receives an additional moment and immersed to a greater depth. Upon further rotation of wheel mover soil under the Shoe 8 is sealed and prevents further movement of the lug 3, thus creating the necessary support for the clamping action of the lug, which received the vehicle due to the action of the horizontal component from the power of the P1stops slipping and moving forward. Upon further rotation of wheel mover due to the fact that the lugs-plunger can be rotated relative to the finger in a plane parallel to the plane of the disc, the force R1lasts as long as the following lugs-plunger will not receive support. After this nastup the t moment when the action of the holding force is weakened so that the force of the return action of the spring 9 causes the lugs-plunger 3 to return to the disabled state.

Wheel propulsion, containing a pneumatic tire, rim, disc, rod lugs, each of which is pivoted to the fingers, concentrically located relative to the center of the disk at a distance from the outer circumference of the mover, the length of the rod lug more value and, wherein each of the lugs is endowed with the properties of the feeding mechanism, equipped with a support Shoe, spring-loaded relative to the disk, and only one of its end hinged to the finger at an angle to the axial line of the wheel can be rotated in the plane of the disk.
