Wheel thruster

FIELD: transport.

SUBSTANCE: wheel thruster comprises air tire, wheel tread, disk, rod-type grousers, each pivoted to pins concentrically arranged with respect to disk center at distance "a" from thruster outer circumference. Grouser rod length exceeds "a". Each grouser functions as pusher and is furnished with backup shoe. It is spring loaded with respect to disk and has only one its end pivoted at an angle to wheel axial lines to turn in the wheel plane. Backup shoe represents a flat with grouser rigidly fitted thereon, perpendicular to aforesaid flat, and pivoted on grouser-pusher free end to turn in the disk plane.

EFFECT: reduced harmful effects on soil.

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

Technical challenge is the reduction of harmful effects on the soil wheeled vehicles due to the exclusion of vikorchovuvaly upper bearing layer of soil elements wheeled propulsion.

Known wheel propulsion, containing a pneumatic tire, rim, disc symmetrically arranged on its circumference fingers are pivotally installed additional lug is 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 disadvantages of these devices are their passivity in the implementation of the traction wheel mover and a short period holding force of the lug.

A prototype of the selected wheel propulsion (patent No. 2265526), which contains the 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 "a" from the outer circumference of the mover, the length of the rod lug more than the value "a". Each of the lugs is endowed with the properties of pushing is his 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. The disadvantage of this thruster is the uprooting soil lugs-pusher return it in an inactive state.

Technical challenge is the exception vikorchovuvaly soil by changing the position of the support Shoe in the active state.

1 shows a wheeled mover in an inactive state, side view; figure 2 shows a wheeled mover in the movement kabonesa ground, side view.

To solve this technical problem is proposed wheel propulsion, which 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 support Shoe, which contains plate 8 rigidly mounted perpendicularly thereto, a plate-pochodzace 9 and earring 10 for pivotally mounting the free end of the rod 7 by means of the finger 11. Support Shoe can be rotated in a plane parallel to the plane of the disc 4. The lug-t is lately 3 are arranged at an angle 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 disk 4 by means of a spring 12 and is rotatable relative to the finger 5 in the plane of the disc 4 on the angle, the magnitude of which is limited to the return action of the spring 12.

Wheel propulsion works as follows. When driving on a hard surface road surface every lugs-plunger 3 by means of a spring 12 is in an inactive state so that the support Shoe is not in contact with the surface and apart in the face of the disk 4. When driving off-road wheel propulsion sinks into the soil to a certain depth so that when you turn the wheel plate pochodzace 9 buried by the disk 4 and the pressure plate 8 is horizontal supporting surface of the soil, due to the swivel with the rod 7. In case of slippage by increasing the peripheral speed of the wheel propulsion the lugs-plunger 3 receives an additional point, which leads to pressure on the soil support platform 8. Upon further rotation of wheel mover soil is compacted under the reference area 8, and the plate - pochodzace 9 prevents slippage of the support Shoe, thus creating the necessary support for the clamping action of the rod 7, which received the vehicle due to the action of the mountains of the horizontal component of the force R 1stops slipping and moving forward.

Upon further rotation of wheel mover due to the fact that the lugs-plunger 3 can be rotated relative to the finger 5 in a plane parallel to the plane of the disc 4, the force P1lasts as long as the following lugs-plunger 3 will not receive support. Then comes the moment when the action of the holding force is weakened so that the force of the return action of the spring 12 causes the lugs-plunger 3 to return to the inactive state, not wykonczenia ground support Shoe as support Shoe, due to the swivel with a barbell 7 was located horizontally and was not buried.

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 "a" from the outer circumference of the mover, the length of the rod lug more than the value "a", and 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, wherein the support Shoe is made in the form area of the DKI is rigidly installed perpendicular to her plate focusarea and hinged to the free end of the rod lug-pusher can be rotated in the plane of the disk.

FIELD: agriculture.

SUBSTANCE: invention relates to vehicles, used mainly for agricultural works. The method includes application of additional supports by inserting them into the more compact layer of subsurface soil in closed state. Then supports are opened extending thereby the area of contact and reducing pressure of the wheeled propelling device tires to the top layers of soil. The associated device consists of an axle fixed in the wheel crown disc. The above axle fixes position of the guiding bracket. There is a movable rack inside the above guiding bracket. The device is also provided with jaw having ellipse-shaped working surface. The jaw is installed on a fixed axle so that it can rotate. Besides, the rotation axis is shifted from ellipse symmetry axis by the value of rack advancing. There is a support with triangle-shaped working surface in the lower part of the rack. The support is hinge installed on its axis. There is a roller in the upper part of the rack. The roller can roll over the above jaw surface.

EFFECT: improved functional properties of propelling device due to reduction of adverse effect to ground and improvement of pulling and coupling properties of vehicle wheel.
